Press Release (September 13th, 2010)

New versions: cFosSpeed v6.0 with major features!

cFosSpeed is a network driver which attaches itself to existing Internet connections. It optimises data transfer by means of Traffic Shaping. Traffic Shaping is a method for optimizing Internet traffic that allows maximum transfer speed while ensuring minimal ping time.

cFosSpeed supports a wide variety of connection types like DSL, cable, UMTS, ISDN, etc.

The most important features about this version are:

• Decisive Traffic Shaping improvements:

  cFosSpeed Traffic Shaping now also optimizes mobile connections. UMTS, WCDMA, CDMA 2000, etc. have highly varying ping times. Under normal conditions this can lead to high latency and/or low throughput rates. Therefore cFosSpeed determines the "normal" ping time and its statistical deviation. These additional statistics are used for the speed regulation in Traffic Shaping, so that the transfer rate will remain high, even if ping times are higher for a short time. This gets the maximum out of mobile connections.

  For fixed-line connections, like DSL and cable, cFosSpeed uses these statistics for sharper limits of the allowed ping time and can therefore reduce the latency by ca. 20 msec. The effect particularly shows with today's fast Internet connections, for example with games, VoIP and today's Web 2.0 pages with their frequent and small HTTP packets (interactive traffic).

  By improving the ping engine cFosSpeed can now be used with connections which already employ other prioritization techniques, such as ACK- and ping-prioritizing routers. The benefit is a drastically reduced latency, as well as cFosSpeed's unique RX-shaping and protocol-prioritization. Without these functions a single data stream can congest the connection and impair the quality of other applications.

  The TCP window auto-tuning used in Windows Vista and Windows 7 accelerates the regulation of RX-shaping, because the initial TCP windows size has far lower (more realistic) values and therefore does not need to be corrected so heavily. A luxury only available when you already have nice, low latency.

• The new status windows now illustrate how cFosSpeed Traffic Shaping works. The "ping variance" display informs you about the current ping time variation and the reliability of the statistical data. These statistics will be re-evaluated every few minutes, as for mobile connection these values can change quickly during movement (travelling) or by changing utilization of radio cells.

  The "Traffic Shaping Indicator" notifies you whenever cFosSpeed re-orders packets (which is one of the most important actions of Traffic Shaping). "Small blip - big change". The ping time is another indicator by which you can verify that the reaction time is nice and low even when your connection is heavily used.

  In addition the configurable real-time analysis shows which protocols and programs currently use which amount of bandwidth.

• Further Traffic Shaping optimizations:

  Net Talk is a new feature, which allows you to use Traffic Shaping with several PCs in a LAN. With Net Talk all PCs inform each other about their respective send and receive statistics and use this information to control Traffic Shaping far more precisely. With simultaneous use of the ping variance statistics, it can help to detect rising ping times quickly and then counter it.

  Based on the shared statistics Traffic Shaping works more accurately, since every member of the LAN knows about the traffic of all others.

  The priority queues have been optimized (reduced) with regard to Compound TCP, now used in Windows Vista and Windows 7. Compound TCP is designed to detect early congestion and then reduce the send speed. Now cFosSpeed and Compound TCP work hand in hand: Compound TCP ensures a fast maximum sending speed while cFosSpeed meanwhile keeps the latency low.

• New NDIS 6 driver:

  cFosSpeed now contains a NDIS 6 driver for Vista. It automatically switches to NDIS 6.20 for Windows 7 and supports all the "speed-features" available in Microsoft's new network architecture, like dispatch-level tracking, data copy avoidance, early packet classification, etc. These features reduce the CPU load caused by network activity.

  The new NDIS 6.20 driver also supports the Windows 7 Mobile Broadband Platform, the new driver architecture for mobile connection sticks.

• WLAN: Our tests have shown that with only moderate signal strength not only the transfer rate can by degrade 10% or more, but also the ping time begins to vary more than 50 msec, depending on WLAN utilisation. In this case cFosSpeed's new ping variance detection also helps to keep transfer speeds and pings in comfortable ranges.
• The new "Adapter Info" dialog makes all important parameters of the network adapters visible, especially for WLAN and WWAN (Mobile Broadband). For WLAN cFosSpeed also produces a channel recommendation. cFosSpeed calculates it by the number and signal strength of other WLAN access points in the vicinity and then selects the channel with the currently lowest frequency utilisation. You can use this as a hint to switch your WLAN access point to this channel, minimizing the risk of packet collisions.
• New dialogs for the configurable TX limits for individual programs and protocols.
• The new DivX webplayer as well as Teredo for IPv6 tunneling (for example used by Bittorrent) are now detected by cFosSpeed's layer-7 analysis and prioritized accordingly.
• Support for the Microsoft's security functions Data Execution Prevention (DEP) und Address space layout randomization (ASLR) for protections against attacks.
• Tons of other improvements and bugfixes, for details see WHATSNEW.TXT or http://www.cfos.com/cfosspeed/whats-new.htm

Press Release (March 18th, 2010 )

New cfos IPv6 Link v2.50 with major features!

Connectivity with the new IPv6 network.

cfos IPv6 Link allows dial-up with IPv6 for Windows XP and Vista. Simply configure the dial-up connection to your ISP and you're IPv6-ready! Not only does cfos IPv6 Link connect to the new IPv6 network, but it also configures routing and IP and DNS addresses automatically.

Major features of the new version are:

• NAT46 mapping. This allows IPv4-only software to be used with IPv6. To accomplish this, cfos IPv6 Link maps the IPv4 addresses to IPv6 addresses (and vice-versa). cfos IPv6 Link supports NAT46 for outgoing as well as incoming connections. This allows easy migration from IPv4 to IPv6.
• cfos IPv6 Link now supports multiple address prefixes, e.g. by Router Advertisement or DHCPv6 (prefix delegation), as well as statically assigned prefixes. Also cfos IPv6 Link now supports policy table updates according to RFC 3484 by means of DHCPv6 option OPTION_DASP.
• cfos IPv6 Link now supports DHCPv6 custom options. Third party applications, like ISPs dial-up software, can now query cfos IPv6 Link for DHCPv6 options (stateful and stateless) and use them to configure the system.

You can find artwork, screenshots and boxshots which may be used for free by journalists here .

cfos IPv6 Link is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.com/download/download.htm ) or as the full version for €29,90.

Press Release (October 28th, 2009)

cFosSpeed, new Version 5.00, now with real-time Traffic Analysis & new Pinger!

cFosSpeed is a network driver which attaches itself to existing Internet connections. It optimises data transfer by means of Traffic Shaping. Traffic Shaping is a method for optimising Internet traffic that allows maximum transfer speed while ensuring minimal ping time.

cFosSpeed supports a wide variety of connection types like DSL, cable, UMTS, ISDN, etc.

The most important improvements of this version are:

• Real-time Traffic Analysis: cFosSpeed can analyse traffic for different protocols and used programs and visualize these different traffic streams graphically in real-time. To do that there are two new status windows and a new dialog, by which the user can setup the assignment of different traffic streams to the respective graphs. This allows detailed analysis and thus comprehensive knowledge which traffic streams use how much bandwidth.
• New dynamic Ping Engine: for traffic shaping to function properly, cFosSpeed must know when the Internet connection begins to congest, i.e. when the ping time to the next hop begins to increase. This is now probed in a much more reliable and much more precise way. cFosSpeed can now simultaneously use up to 5 different ping variants, each for different hops respectively: ICMP, UDP and TCP in kernel-mode and ICMP, UDP in user-mode. Thereby the pings can pass common firewalls and filters in routers more reliably. cFosSpeed can even switch from one pinger to another dynamically during normal operations.
• cFosSpeed is Windows 7 compatible.
• Complete optical overhaul of the user interface; adapted to Vista / Windows 7.
• More improvements of the Layer-7 Protocol Analysis, especially the RTP (Voice over IP) and SSL / SSH (Bulk Mode) detection.
• IP filter-lists now support the Protowall / Peerguardian format.
• Lots of further improvements, see WHATSNEW.TXT.

Press Release (February 11th, 2009)

cFosSpeed, new Version 4.50 now with prioritisation for web-surfing.

cFosSpeed is a network driver which attaches itself to existing Internet connections. It optimises data transfer by means of Traffic Shaping. Traffic Shaping is a method for optimising Internet traffic. It allows maximum speed while ensuring minimal ping..

cFosSpeed supports a wide variety of connection types, like DSL, cable, ISDN, UMTS, etc.

Important feature of this version is the differentiation between HTTP web-surfing and HTTP downloads. Thereby cFosSpeed can give web-surfung precedence and limit the bandwidth for HTTP downloads. Web-surfing is an interactive Internet use and needs a responsive connection while HTTP downloads can usually be limited, if the available bandwidth is required for more important tasks. With the dialog for protocol prioritisation the user can adjust the precedence of HTTP accordingly.

cFos IPv6 Link is available either as a 30-day trial version (which can be downloaded for free at our download page ) or as the full version for €14,90 .

Press Release (July 23rd, 2008)

cFos IPv6 Link, Connectivity with the new IPv6.

cFos IPv6 Link allows Dial-Up with IPv6 for Windows XP und Vista. While Vista partly supports PPP Dial-Up into the IPv6, Windows XP has no PPP stack capable of IPv6 dial-up. In this case cFos IPv6 Link offers users of Windows XP to connect to the IPv6 network. Also under Windows Vista there are great advantages. For example it handles the automatic configuration of all connection parameters and is much faster than the driver shipped with Vista.

Everyone who wants to try cFos IPv6 Link, can use it with a DSL modem or an IPv4 router, which supports PPPoE-Passthrough.

cFos IPv6 Link supports the typical IPv6 address- and routing auto-configuration with

• Pv6 Neighbor discovery (ND) + DAD
• IPv6 Router Advertisement
• IPv6 DHCP (DHCPv6) statefull & stateless
• IPv6 Router Solicitation with ISP
• DHCPv6 with ISP

In addition cFos IPv6 Link has a DNS mapper, which translates IPv4- and IPv6 DNS queries into queries for the IPv6 and into IPv4 if no IPv6 DNS server is known.

cFos IPv6 Link is available either as a 30-day trial version (which can be downloaded for free at our download page ) or as the full version for €29,- .

Press Release (March 28th, 2008)

cFos Broadband Connect, new PPPoE dial-up driver for high-speed Internet.

cFos Broadband Connect is a network driver for very fast PPPoE Internet access, like DSL and Cable. While the driver shipped with Windows can only transfer up to 4.5 Mbyte/s (= 36 Mbit/s), cFos Broadband Connect sends up to 50 Mbyte/s (= 400 Mbit/s), tested with Gigabit LAN, Pentium 4 (3GHz).

cFos Broadband Connect is designed for maximum throughput under minimum CPU load. This leaves your CPU power to the actual Internet application, like media players, etc. At full speed cFos Broadband Connect needs only 3% CPU time.

cFos Broadband Connect supports all important PPPoE parameters. These can easily be configured with the phone number used for the Dial-Up connection. With Auto-Detect cFos Broadband Connect finds all Internet access points connected to your system.

cFos Broadband Connect can also accept incoming calls. This way, you can set up your own PPPoE server.

cFos Broadband Connect allows multiple PPPoE sessions simultaneously. You can use any number of incoming and outgoing sessions. With the 'Service-Name' and 'AC-Name' parameters you can restrict connections to certain services or access points.

cFos Broadband Connect supports NDIS 6 under Vista, thereby providing even more network performance.

cFos Broadband Connect is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.com/download/download.htm ) or as the full version, currently starting at a special offer price of €9,95.

Press Release (June 20th, 2007)

cFosSpeed v4.0, Traffic Shaping with Multi-User Mode!

cFosSpeed is a network driver that optimises data transfer through Traffic Shaping. This technology allows cFosSpeed to minimise ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/traffic-shaping/traffic-shaping.htm

Highlights of the new version include:

• Multi-User Mode:
  

  The new Traffic Shaping in cFosSpeed allows use of several PCs connected to one router. In this scenario the available bandwidth can change rapidly. cFosSpeed detects such changes and manages the data transfer so that ping times are good and no PC chokes another.

  One Traffic Shaping variant provides good results even if there is a PC in the network with no cFosSpeed Traffic Shaping, e.g. Linux or Playstation.

  In Multi-User mode there may be the need to restrict the throughput of an individual PC. Therefore cFosSpeed now offers fixed bandwidth limits. You can then, for example, reserve a minimum bandwidth for other PCs with interactive applications.

Our WHATSNEW.TXT provides a full list of changes.

cFosSpeed is available either as a 30-day trial version (which can be downloaded for free at our download page ) or as the full cFosSpeed/Professional version, currently starting at a special offer price of €9,95.

cFosSpeed v3.10, important update for Bittorrent users!

cFosSpeed is a network driver that optimizes data transfer through Traffic Shaping. This technology allows cFosSpeed to minimize ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/traffic-shaping/traffic-shaping.htm

Highlights of the new version include::

• Not only does cFosSpeed Traffic Shaping manage upstream data traffic, but it also controls downstream data reception. This new type of RX shaping is even better suited to support peer-to-peer applications with multiple connections running at the same time. As a result, even with as many as 500 connections already open, additional Internet applications can still be run with ease.
• The cFos online budgets to keep track of time spent online and volume used has now been integrated into cFosSpeed as well. This is particularly useful for those on broadband without a flat rate. In addition, data traffic is now presented in graphical format, making it possible to have different graphics displayed for budgets, programs, and protocols used.
• Tested for both 32-bit and 64-bit Vista Beta 2.
• A host of minor improvements including additional options for routing and IP configuration plus a new status-window control panel.

Press Release June 02, 2006

cFos v7.0 64-bit ISDN and DSL Driver uncovered!

Following up on its initial finds of 16-bit CAPI FOSSILS in early DOS deposits and later discoveries of 32-bit specimens in Windolithic layers, a team of cFos-O-logists led by Chris Lueders and Martin Winkler have now unearthed a 64-bit version of this once widespread genus of ISDN and DSL drivers in the skeletal remains of a recently excavated x64 Windosaurus. This proves that the cFos family belonged to only a select few driver species that succeeded in doubling bitwidth twice during their evolution

Hailed as a sensational find, this also calls into question long-established theories that posit such software had been under threat of extinction with the imminent rise of broadband networks. Windologists cite an amazing adaptability to new developments in telecommunications as the primary reason for the enduring popularity of cFos drivers. The ability to establish symbiotic relationships with both time-tested software and new technologies seems to have been of utmost importance for this. Thus, not only could the 64-bit drivers link up with ISDN cards still extant at that time, but they did also optimize the performance of broadband networks – by letting them achieve higher data throughput and low ping times through Traffic Shaping.

By participating in a 30-day trial program, eager scientists now hope to find out more about unique abilities exhibited by the latest CAPI fossil, such as:

• fully integrated 64-bit support (including 64-bit Kernel-Mode CAPI and CAPI2064.DLL)
• Traffic Shaping with Layer-7 protocol detection: Recognition of the 25 most important protocols
  (including HTTP, FTP, POP3, filesharing/P2P, streaming media, and VoIP)
• adaptivity to high-end bandwidth (like ADSL2+)
• Traffic Shaping for ISDN
• numerous other evolutionary leaps like advanced Multilink-PPP support and a fully switchable firewall

However, prior to any such research, the 64-bit version must first be downloaded in full from:

www.cfos.com/download/download.htm

cFos-O-logists under the leadership of Chris Lueders and Martin Winkler have been researching the development and evolutionary history of cFos drivers in disparate habitats for more than 13 years. The main scientific focus has always been on different adaptation techniques to new conditions. One such strategy is Traffic Shaping, which has been successfully demonstrated for both cFos and cFosSpeed.

Press Release May 15, 2006

cFosSpeed v3.0 major update with tons of new features and functions!

cFosSpeed is a network driver that optimizes data transfer through Traffic Shaping. This technology allows cFosSpeed to minimize ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/en/traffic-shaping/traffic-shaping.htm

Highlights of the new version include:

• Layer 7 protocol detection: cFosSpeed detects which protocols are being used based on packet content not on port numbers.
  
  This provides users with a quick and easy way to configure data traffic down to the last minutiae. The following protocols can be prioritized in this fashion:
  
  Standard protocols: HTTP, FTP, POP3, SMTP, IMAP4
  Voice-over-IP: RTP, RTCP, SIP
  Special protocols: Telnet, SSH, SSL, IRC, DNS, (S)NTP, RPC
  Filesharing/P2P: eDonkey, Kazaa, Bittorrent, Kademlia, Gnutella(2), Direct Connect Streaming media: RTSP and HTTP streams with miscellaneous player software.
  
  All protocols can be prioritized individually. The cFosSpeed console window provides a realtime overview of all active connections and protocols.
  
  This also means that cFosSpeed can use Internet Connection Sharing (ICS) to prioritize the data traffic of multiple users simultaneously.
  
  
• The new connectivity engine makes it possible to run multiple Internet connections at the same time - each with different Traffic Shaping settings. It also permits use of VPN and routing for RAS (RRAS).
• For optimal Traffic Shaping configuration, cFosSpeed now fully supports all of the following broadband media: PPPoE, PPPoA (LLC & VCmux), PPTP, Cable, ISDN, and IP over AAL5.
• Full 64-bit support for all Windows x64 editions. All cFosSpeed components are fully 64-bit capable.
• Switchable firewall function with packet filtering, state inspection, stealth mode, plus optional ingress and egress filtering. This makes cFosSpeed one of the few firewall solutions available for x64!
• Traffic Shaping for ISDN.
• Numerous minor Traffic Shaping improvements for ensuring ping times are kept to a minimum while transfer rates remain at max. Among other additional features, cFosSpeed does now support IP fragmentation.
• New fine-tuning dialogues.

The WHATSNEW.TXT provides an itemized list of all changes (running more than 250 lines total).

cFosSpeed is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.de/en/download/download.htm) or as the full cFosSpeed/Professional version, currently starting at a special offer price of €9.

Press Release August 01, 2005

cFosSpeed v2.10, new improved quality for Voice-over-IP (VoIP)

cFosSpeed is a Traffic Shaping driver that sorts Internet packets according to their relative importance. Besides optimizing Internet traffic, cFosSpeed also produces extremely low ping times - essential for interactive applications and games.

What's new in this version:

• RTP (real-time transport protocol, RFC 2550) prioritization for Voice-over-IP and other multimedia applications
• A new skin for including your own background pictures
• Improved Traffic Shaping
• Now with Turkish language support

What is Traffic Shaping?

Traffic Shaping analyzes incoming and outgoing Internet traffic and prioritizes time-critical data packets (like TCP ACKs), making sure they are sent prior to other packets. On top of that, cFosSpeed achieves very low latency through optimized transmission.

Details and test results are available at http://www.cfos.de/en/traffic-shaping/traffic_shaping.htm. This is also where you'll find an easy way for users to test the effects of Traffic Shaping for themselves.

For more info on how cFosSpeed optimizes Internet traffic compared to methods utilized by other programs, refer to http://www.cfos.de/en/traffic-shaping/tuning.htm.

cFosSpeed is available either as a 30-day trial version (which can be downloaded for free at www.cfos.com/download/download.htm) or as the full cFosSpeed/Professional version, starting at �29.

Supported Operating Systems:

Windows 2000, Windows XP (Home & Professional) and Windows Server 2003

Press Release May 25, 2005

cFos v6.0 now with new Traffic Shaping technology!

Important updates and new features:

• New Traffic Shaping with programmable rules.

  Traffic Shaping yields optimal Ping times while ensuring maximum Upload and Download Rates. This is achieved in three ways:

  It reprioritizes data packets in such a fashion that optimal transfer rates are achieved (ACKs, for instance, are sent out prior to other data). By default, cFos Traffic Shaping manages six priority queues. In doing so, it differentiates between various protocols (such as HTTP, FTP, POP3, SMTP, ICMP, SSH, Telnet, DNS, etc.) and reprioritizes them accordingly. This is to make sure that different applications will interfere with each other as little as possible.

  The data stream is realigned in such a way that as little congestion as possible occurs, allowing ping times to remain low. This will in turn result in fast response times while surfing the Net or playing online.

  The ACK filtering employed by cFos effectively halves the bandwidth needed for sending ACKs. Additional bandwidth is thus freed up and becomes available for uploads!

  More details including test results can be found at http://www.cfos.com/traffic-shaping/traffic_shaping.htm . Besides printable material, you will also find an animated graphic there showing how Traffic Shaping technology works.

• Individual program prioritization

  Since programs can easily be prioritized up or down individually, cFosSpeed Traffic Shaping allows users to get the most out of online games, filesharing programs, voice-over-IP and other multimedia applications. This way, gamers will benefit from lower ping times, while filesharing programs can be run in the background without choking a connection's upstream channel.

• Further new features:

  Redesigned firewall with programmable rules

  Icon Skins; display cFos status in the taskbar

  New languages: French, Spanish, Japanese and Korean

cFos is available either as a 45-day trial version (which can be downloaded for free at http://www.cfos.de/en/download/download.htm) or - starting at € 45 - as the full cFos/Professional version.

Supported Operating Systems:

Windows 2000, Windows XP (Home & Professional), Windows Server 2003 as well as Windows 9x and Windows Me.

Press Release February 18, 2005

cFosSpeed v2.0 now with next-generation Traffic Shaping technology!

Important updates and new features:

• More upstream bandwidth
  

  By optimizing TCP ACKS during downloads, the new cFosSpeed ACK filter increases available upstream bandwidth dramatically, often even tripling it. Since TCP ACKs take up roughly one-tenth of a download's bandwidth in the upload channel, a DSL 2000 connection with an upstream of 192 kbps could for instance not quite achieve full download speed until now. But with cFosSpeed this is finally possible! For DSL 2000, there are now approximately 13 kbps available for uploads during a full download. For a DSL 1000 connection, available upload bandwidth is doubled from 6 to 12 kpbs.

• Individual program prioritization
  

  Since programs can easily be prioritized up or down individually, cFosSpeed Traffic Shaping allows users to get the most out of online games, filesharing programs, voice-over-IP and other multimedia applications. This way, gamers will benefit from lower ping times, while filesharing programs can be run in the background without choking a connection's upstream channel.

• Low-latency mode
  

  Low ping times are especially vital for online games and voice over IP. In low-latency mode, cFosSpeed will still maximize available bandwidth but not at the expense of low ping times. In bandwidth mode, cFosSpeed minimizes ping times but without sacrificing available bandwidth. Some test results on this can be found in the WHATSNEW.TXT file. Thus, gamers who have already prioritized their online games can further decrease ping times during other ongoing traffic by switching to low-latency mode.

• Icon windows
  

  For optimal integration with the user interface, cFosSpeed skin windows can now be included on the Windows taskbar. The new icon skin looks great!

• Improved language support
  

  In addition to German, English, Polish, and (both traditional & simplified) Chinese, cFosSpeed is now also available in French, Spanish, Italian, Japanese, and Korean.

What exactly does Dynamic Traffic Shaping do?

In essence, it boosts download speed without sacrificing surfing speed - making cFosSpeed a true Internet accelerator for Windows!

cFosSpeed Traffic Shaping accomplishes this by making sure bidirectional DSL bandwith is optimally used so that delays during downloads can be kept to a minimum.

More specifically, it controls TCP connection timing, thereby cutting down on latency and the related drop in transfer rates. What's more, cFosSpeed does so without artificially limiting the bandwidth of individual data streams. Nor is it necessary to know in advance how much bandwidth will be taken up by each of those streams.

More details including test results can be found at http://www.cfos.com/traffic-shaping/traffic_shaping.htm. Besides printable material, you will also find an animated graphic there showing how Traffic Shaping technology works.

cFosSpeed is available either as a 45-day trial version (which can be downloaded for free at www.cfos.com/download) or - starting at €29 - as the full cFosSpeed/Professional version.

Presseerklärung vom 05.02.2003

Neue cFos Version 5.0 mit Surfbeschleunigung / Internet Tuning

• Bis zu dreimal schneller Surfen mit cFos Traffic Shaping!
• Neues Verfahren reduziert Wartezeiten beim Datentransfer
• Endlich die volle Bandbreite des DSL Anschlusses ausnutzen

Was ist cFos ?

cFos ist ein DSL und ISDN Treiber, den man mit dem DFÜ-Netz und/oder nahezu allen Modem-Programmen einsetzen kann, um mit ISDN und/oder DSL (PPPoE) zu kommunizieren. cFos enthält jede Menge Zusatz-Funktionen mit denen man den DSL und ISDN Anschluss optimal nutzen kann.

Neuigkeiten der cFos Version 5.0

• cFos Traffic Shaping:
  
  

  Erste echte Surfbeschleunigung unter Windows!

  cFos Traffic Shaping sorgt dafür, dass die Bandbreite eines DSL-Anschlusses in beide Richtungen voll ausgenutzt wird und trotz Datentransfers keine hohen Wartezeiten beim Surfen auftreten.

  cFos steuert das Zeitverhalten der TCP Verbindungen und verhindert so verlängerte Ping-Zeiten und damit verbundene Einbrüche in der Transferrate. Dafür müssen dank cFos weder einzelne Steams künstlich beschränkt werden, noch deren Bandbreite im Vorfeld bekannt sein.

  Näheres, insbesondere eindrucksvolle Testergebnisse, finden sich auf http://www.cfos.de/en/traffic-shaping/traffic-shaping.htm

• Verbesserte "stateful" Firewall:
  
  

  cFos enthält jetzt nicht nur einen Paketfilter, sondern auch eine "echte" Firewall, die den Zustand der TCP/IP Verbindungen überwacht.

  Hinweis: Wir haben festgestellt, dass bei manchen lokalen Anbietern (besonders mit Flatrates) so viel Bandbreite mit eingehenden Verbindungsanfragen von File-Sharing Programmen verbraucht wird, dass die Antworten darauf die Upstream-Bandbreite übersteigen würden. Ohne Firewall kommt dies einer dauerhaften "Denial of Service" Attacke gleich. Mit Firewall werden diese Anfragen ignoriert und die Upstream Bandbreite bleibt für Nutzdaten erhalten.

• Zeit-Synchronisation nicht nur via ISDN, sondern auch via Internet Time Server (mittels SNTP). Damit ist auch mit DSL die Rechner-Zeit immer korrekt.
  
  
• Überarbeitetes Skin mit Alphablending und Farbtransformation.
  
  
• Smart Inactivity Timer: Als Aktivität werden jetzt nur noch Daten- Transfers gezählt, die vom Benutzer initiiert wurden. Damit können z.B. Port-Scans und unerwünschte Verbindungsanfragen das Auflegen bei Inaktivität nicht mehr verhindern.
  
  
• Weitere Neuerungen siehe WHATSNEW.TXT der aktuellen cFos Version 5.0.
  
  

cFos gibt es in einer kostenlosen 45 Tage Testversion und ab 45 EUR in der Vollversion cFos/Professional.

Systeme:
cFos unterstützt Windows 9x/Me, NT 4.0, Windows 2000 und Windows XP (Home und Professional).

Presseerklärung vom 15.10.2002

cFos stellt neue Freeware "hrPING" zum Download zur Verfuegung

hrPING ist ein Ersatz fuer das Windows-eigene Ping-Programm.

hrPING bietet, gegenueber dem Standard-Ping folgende Vorteile:

• wesentlich genauere Ping-Zeiten: Da Timings unter Windows Ungenauigkeiten von bis zu 10 Millisekunden aufweisen, taugt der Standard-Ping zum Ausmessen von High-Speed Anschluessen, wie z.B. DSL nichts. hrPING nutzt fuer alle Timings den in Pentium-Class Prozessoren eingebauten Instruction-Timer (TSC), der mit jedem Takt hochgezaehlt wird. Dadurch erzielt hrPING mikrosekunden-genaue Messungen. Dies ist z.B. wichtig, wenn man DSL Anschluesse ausmessen moechte, bei denen Fastpath (Ping-Zeiten von ein paar Millisekunden) oder Short-Interleave (Ping-Zeiten von ca. 10 msec.) geschaltet ist.
• verbesserte Statistiken: hrPing fuehrt ueber alle Pings Statistiken und ermittelt Minimum, Maximum und durchschnittliche Dauer. hrPING kann man hierbei im "Endlos-Modus" laufen lassen. Dann generiert hrPING solange Pings, bis man dies mit CTRL-C abbricht. Dann werden aber, im Gegensatz zum Standard-Ping ebenfalls Statistiken ausgegeben.
• Timings und Statistiken auch fuer ICMP Fehlermeldungen (z.B. TTL expired). Dies ist z.B. zum Ausmessen von Routen nuetzlich.
• Overlapped Pings, wie unter Linux ueblich: hrPING kann mehrere Pings gleichzeitig senden, ohne erst auf die Anwort der vorigen Pings zu warten.
• Eingebautes Traceroute
• Alle relevanten Parameter, z.B. Groesse der Ping-Pakete, TTL, Timeouts, sind einstellbar.

hrPING gibt es in der Version 2.01 und ist Freeware!

Systeme:
hrPING unterstuetzt Win 9x/Me, NT 4.0, Windows 2000 und Windows XP (Home und Professional)

Presseerklärung vom 22.12.2001

Neue cFos DSL uns ISDN Treiber zum Download auf www.cfos.de verfügbar.

Seit heute stehen neue cFos Versionen 4.12 zum Download bereit.

Neuigkeiten:

• 0190er-Blocker und neues Produkt names "cFos Watch":
  
  Damit schützt cFos auf zweierlei Arten vor bösen Überraschungen durch teure Internet-Dialer.
  
  cFos kann die Rufnummern aller cFos Modems überwachen und bietet zusätzliches DFÜ-Netzwerk Überwachung, so dass auch dann Schutz gewährleistet ist, wenn die Verbindung gar nicht über cFos aufgebaut ist, z.B. bei einem DSL Benutzer, der noch ein analoges Modem zum Fax- Empfang betreibt. In diesem Falle könnte ein Dialer nämlich versuchen, eine Verbindung über das Analogmodem aufzubauen, obwohl mit DSL selbst ja keine Wählverbindungen möglich sind.
  
  cFos und cFos Watch bieten die Möglichkeit, bestimmte Vorwahlen ganz zu verbieten und andere in eine Liste zu warnender Nummern einzutragen. In diesem Fall zeigen cFos und cFos Watch eine Messagebox mit der Rufnummer an, so dass man im Einzelfall entscheiden kann, ob die Verbindung erlaubt ist.
  
  cFos kann auch 010xx und 0100xx Call-by-Call Vorwahlen berücksichtigen, sowie gleichzeitiges Betreiben von Geräten mit und ohne Amtnetzkennzahl.
  
  Die 0190er Blocker Funktionalität ist in die cFos Treiber eingebaut. Zusätzlich steht Überwachung der DFÜ-Netz Verbindungen in cFos Watch als separates Programm zur Verfügung.
  
  Damit bieten wir auch eine Lösung für diejenigen, die cFos nicht nutzen, z.B. von Benutzer von Analogmodems.
  
  
• Erweiterte Internet-Funktionalität durch "Minimum-Klick" Setup Dialoge zur optimalen Einrichtung von DFÜ-Netz Verbindungen über cFos, Inactivity Logout, schnellen Logoff im cFos Kontextmenü, High-Speed Login, ...
  
• Verbesserte Firewall Funktionalität
  
• Anpassung an die kürzlich erfolgte Umstellung der Telekom Breitband Knoten, so dass jetzt wieder der cFos High-Speed Login allen zur Verfügung steht.
  

Systeme:

Die cFos Treiber gibt es für Windows 95, 98, Me und Windows NT 4, 2000 und XP. Weiterhin bieten wir cFos ISDN Treiber für OS/2 und DOS und sogar eine Version für Win 3.11.

Preise:
cFos 4.12 ab 45,- EUR
cFosWatch 19,- EUR

AOL Mitglieder können die cFos Treiber im Rahmen einer Sonderaktion
zu einem Spezial-Preis von 39,- EUR erwerben.

Presseerklärung vom 16.1.2001

Neue cFos-Versionen / GmbH-Gründung / Freeware zum Download

Die cFos Lüders/Winkler GbR wurde zum Jahreswechsel in die cFos Software
GmbH umgewandelt. Anläßlich dieser Umstellung bringen wir folgende Neuigkeiten:

1. Neue cFos Versionen , cFos 3.81, für alle Betriebsysteme DOS, Windows
3.x, 9x/Me, Windows NT/2000 und OS/2.

Zu den Highlights der neuen Versionen zählen:

• Mini-Firewall , der die bekannten Windows-Sicherheitsprobleme in Verbindung mit NetBIOS-Ports und Freigabediensten schließt. Weiterhin blockt cFos Denial-of-Service Attacken, die gerade bei ADSL zu Verbindungsabbrüchen führen können. Dies ist besondern für diejenigen gedacht, die sich keine vollwertigen Firewall installieren möchten. Eine Erklärung zum technischen Hintergrund des Mini-Firewall finden Sie hier .
  
  
• Volumen-Budgets . cFos kann nun nicht nur die monatliche Online-Zeit,
  sondern auch die Menge der übertragenen Daten ermitteln, so daß auch
  für "Flatrate"-User, die nach Volumen abgerechnet werden, jederzeit Überblick über die Kosten besteht.
  
  
• Abhilfe für überlaufene T-Online Knoten : Die Breitbandknoten, aber auch
  ISDN-Zugangknoten, lehnen bei Überlastung die PAP-Authentisierung
  ab. Dies verhindert die automatische Neuwahl durch RAS. cFos sorgt in der neuen Version dafür, daß Windows neu anwählt und auch ein evtl. gespeichertes Passwort nicht jedesmal vergisst.
  
  
• Beschleunigter Login mit DSL-Modem-Autodetection . cFos kann sich
  bis zu dreimal schneller als konventionelle Treiber einloggen. Mit der neuen Version geht dies auch, wenn man mehrere Netzwerkkarten im System hat. cFos verwendet dann automatisch die Karte mit dem DSL-Modem.
  
  
• Unterstützung von Internet-Connection Sharing . Zur Konfiguration
  finden Sie eine Anleitung unter www.cfos.de .

Damit ist cFos hinsichtlich Kostenkontrolle und Sicherheit, besonders gut für die aktuellen Flatrate-Angebote optimiert. Aber auch der minutenweise zahlende Internet-User hat jederzeit den Überblick.

Besonders vorteilhaft ist cFos für diejenigen, die neben DSL auch ISDN nutzen, da sie nur noch einen Treiber statt bis zu drei installieren müssen.

2. cFosConnect ist eine kleine Freeware zum Download von www.cfos.de , die bei Überlastung der Knoten unabhängig vom verwendeten Treiber die automatische Neuwahl bis zu 100mal versucht. cFosConnect ist so entwickelt, daß es bestehende RAS Verbindungen nutzt und der Benutzer mit minimalen Mausklicks online gehen kann. Da cFosConnect auf DFÜ-Verbindungen aufsetzt, kann es sowohl für DSL-, ISDN- und Analog-Verbindungen eingesetzt werden.
Ab jetzt hat man also Hilfe bei überlasteten T-Online Knoten oder dauerbesetzten Internet-by-Call Anbietern.

 

Technischer Hintergrund zum Mini-Firewall:

Gerade mit ADSL, aber auch mit ISDN zeigt unsere Erfahrung, daß man nach ca. 20 Minuten Onlinezeit die ersten "Port-Scans" von potentiellen Angreifern auf den lokalen Rechner, selbst auf einer dynamisch zugewiesenen IP-Adresse, sehen kann.
Es gibt im Internet genügend Programme, die nach potentiellen Sicherheitslöchern auf im Internet eingeloggten PCs suchen.

Je nach Betriebssystem gibt es unterschiedliche Sicherheitslücken. Unter Windows 9x und NT/2000 stellen die sogenannten NetBIOS-Ports ein großes Problem dar. Über diese NetBIOS-Ports kann ein Angreifer nicht nur Usernamen und Rechner-Namen erfragen, sondern auch, ob der Benutzer Datei-Freigabe-Dienste aktiviert hat. Sollte dies der Fall sein, gibt es einschlägige Programme, die (gerade mit ADSL) in Sekundenschnelle alle typischen Passwörter für die lokalen Verzeichnisse durchprobieren können. Die Chancen, so Zugriff auf die Dateien zu erhalten, sind so groß, dass in Sicherheitskreisen die NetBIOS-Ports als sogenanntes Scheunentor" betrachtet werden.
In der Stufe 1 des cFos Mini-Firewalls werden daher Zugriffe auf diese
NetBIOS-Ports gesperrt.

Ein zweites Problem, das bei ADSL wegen der unterschiedlichen Übertragungsgeschwindungkeit beim Upload und Download auftreten kann, sind
Denial-of-Service Angriffe. Man kann mehr Daten zum lokalen Rechner senden, als dieser wegen der geringeren Bandbreite in Netzrichtung beantworten kann,
und so verhindern, daß dieser die von den Telekom-Breitband-Knoten in regelmäßigen Abständen erwarteten Echo-Request (Wakeup-Päckchen) versendet. Die Folge ist ein Verbindungsabbruch.
cFos blockt daher alle potentiell gefährlichen ICMP Pakete.

Als zusätzliche Sicherheitsmassnahme können alle "unteren" TCP/UDP Ports
geblockt werden. Damit kann man von außen nicht mehr auf lokal installierte
Server zugreifen, die auf den niedriegen Standard-Portnummern installiert sind (Webserver, Telnet, etc.). In der höchsten Sicherheitsstufe ist es sogar möglich, alle einkommenden TCP Sessions zu verbieten und nur noch ausgehende zu erlauben. Dies hat aber zur Folge, dass FTP-Transfers nur noch im "passiv mode" möglich sind, was aber mit z.B. dem Internet Explorer kein Problem ist.

Um den Mini-Firewall zu aktivieren setzt man das Modem-Register S89. Den Standardwert dieses Registers kann man als globalen Parameter beim Laden von cFos vorgeben (-x89=...), so daß er für alle COM-Ports und cFos-Modems gilt.

Dieser cFos Paket-Filter schützt den Anwender vor bekannten Angriffen von außen. Der Problemkreis, dass aber z.B. heimlich auf dem lokalen PC Installierte Trojaner Daten aktiv nach außen senden oder man verhindern möchte, daß Mitarbeiter über diesen Rechner Firmendaten nach außen senden möchten, wird durch dieses Konzept nicht abgedeckt.
Wer so hohe Sicherheitsanforderungen hat, sollte eine professionelle Firewall Software installieren. Wir empfehlen in diesem Zusammenhang Zonealarm ( www.zonelabs.com ).

Der cFos Mini-Firewall bietet, gerade im Hinblick auf Flatrate-Tarife, aber guten Schutz vor Angriffen von außen, ohne den Anwender mit Sicherheitsfragen und/oder Installation einer weiteren Software zu belasten. Diese zusätzliche Sicherheit bekommt der Anwender bei der Installation von cFos frei Haus mitgeliefert. cFos läßt sich aber auch im Zusammenhang mit Firewall-Software einsetzen und unterstützt daher den Gedanken an ein mehrstufiges Sicherheitskonzept.
