Recent releases

  •  19 Sep 2005 12:07

    Release Notes: This release includes major changes to the filtering system, including recognition of CIDR notation, additional protocol recognition, and automatic protocol name lookup. Interface support has also been expanded.

    •  21 May 2002 10:35

      Release Notes: This release fixes a bug in the detailed interface statistics where packets were not properly filtered out based on their interface name. This caused inaccurate counts and rates on multiple-interface machines such as routers and firewalls. Support for wireless LAN and additional DVB interfaces has also been added.

      •  05 May 2002 22:07

        Release Notes: This is a bugfix release correcting some inaccurate byte counts and data rates, as well as user interface problems.

        •  30 Apr 2002 20:32

          Release Notes: This version supports Token Ring interfaces and has TCP flow rate indicators, further improved sorting, protocol data rates, and wider filter coverage.

          •  15 Aug 2001 15:14

            Release Notes: IPTraf now features a more detailed interface for miscellaneous IP packets (i.e. non-TCP, non-UDP). Faster sorting has been implemented. This version also currects bugs in the scanning code for closed entries, which caused 2.4 to incorrectly mark active TCP entries as ready for disposal. Some minor cosmetic errors were also fixed.

            Great utility!
            This is really easy and simple! Very useful! I am really please with how quickly I can start watching network traffic with little more than an apt-get or yum install.

            Thanks for the project!

            Display problems (perhaps)
            [RedHat 7.2 (with all updates + 2.4.17smp kernel)]
            [iptraf 2.6.1, just built on the same system it's running on]

            1.The TCP connections display seems to link each line with itself instead of linking a pair of lines, and adjacent lines don't seem to be related.

            2. Flow rate never gets above 0.0 Kbytes/sec.

            3. I can' tell if closed TCP connections are being aged properly and dropped from the display. I seem to end up with more and more connections displayed, and many are marked CLOSED.

            A window dump of iptraf on my system is available at

            Are these bugs or operator error?

            Thanks.

            very nice
            iptraf is at this time the best ip traffic monitoring software i've seen
            keep on your good job :)
            i recommend it to every system admin. It's light, it's easy, it's accurate.

            Very Good!
            In the truth, the new interface moved very of versoes previous, very liked it work in top ncurses. He was excellent and of easy manejament.
