What's New

  • Major feature: Added Protocol Layer 7 Detection. From now on, cFos analyzes traffic based on the transferred data rather than the port number used. This gives cFos precise traffic analysis capabilities and thereby allows you fine-grained control over your traffic. cFos detects the following protocols:
  • Commonly used: HTTP, FTP, POP3, SMTP, IMAP4
  • Voice-over IP: RTP, RTCP, SIP
  • Special protocols: Telnet, SSH, SSL, IRC, DNS, (S)NTP, RPC
  • Filesharing: eDonkey, Kazaa, Bittorrent, Kademlia, Gnutella(2),
  • Direct Connect
  • Streaming Media: HTTP-Streams with various Media-Players and RTSP
  • For each protocol cFos distinguishes between client and server mode. All protocols can be prioritized individually. In addition there is a "Connections console" giving you real-time information about the current connections and their detected protocols. User data of these connections can also be recorded into a log file for analysis, see session dumping below.
  • As a by-product you can now use internet connection sharing to connect several computers to the Internet and still have e.g. filesharing traffic prioritized low. The next major release will have additional bandwidth negotiation for multiple PCs connected to a single router.
  • New Technology: cFos is now available as 64-bit version for Windows XP x64 Edition. Driver, Status Window and Setup are true 64-bit programs! The 64-bit version has all the features of the 32-bit version.
  • ISDN support works with CAPI2064.DLL and kernelmode CAPI.
  • Added support for ISDN. From now on ISDN users also benefit from cFos Traffic Shaping! This makes your ISDN connections more responsive by reducing ping times. All the advantages of the broadband Traffic Shaping are now available for ISDN.
  • cFos is now able to traffic shape VJ-compressed connections as well.
  • Added UDP pseudo-connection tracking. UDP packets between two peers are believed to belong to the same connection if they arrive less 10 seconds apart. The pseudo-connections are displayed under "cfo cons" as well. The timeout can be adjusted by the udp_timeout gset variable (the variable is in milliseconds).
  • Added session dump: you can now dump TCP sessions and UDP pseudo-sessions in their own files. This way you can have all packets of one session in one file (and not more). Activate it with "cfo gset dump_sessions 2" and switch on TCP payload dumping with "cfo gset dump_tcp_data 1" (without TCP data dumps there won't be anything interesting for us to see). The maximum file size is set to 100k, if you want to change it use "cfo gset max_session_dump_size 200k" (change "200k" to your liking).
  • All in one line that is:
  • cfo gset dump_sessions 2; gset dump_tcp_data 1
  • "spd gset dump_sessions" accepts the following values:
  • 0 don't dump sessions
  • 2 dump, but delete dump file if there was no data excpet TCP SYNs
  • 3 dump like 2, but delete also if l7-protocol is known.
  • 4 dump and never delete dump file
