iftop with IPv6 support available for testing
by Alexander Reichle-Schmehl 15 Oct '10

15 Oct '10

Hi! Thanks to the work of Mats Erik Andersson, I'm pleased to announce the availability of IPv6 supporting iftop packages for Debian (will most likely also work for all derivatives)! Mats patch allowing IPv6 looks sane and fixes also some other bugs (e.g. a segfault when using console parameters mutliple times). His complete patch is available at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=427852#30 for review. It addresses the following issues: * Add IPv6 support http://bugs.debian.org/427852 * Fix segfault when using the same command line argument multiple time (See http://bugs.debian.org/425488) * Fix typo in display (see http://bugs.debian.org/477928) * Use better hash Algorithm in address pairs (http://bugs.debian.org/595169) * Fix link-level address detection on kfreebsd-* (see http://bugs.debian.org/598367) Packages for testing are available in Debian's experimental branch (should also work on Debian sid/squeeze) and at http://people.debian.org/~tolimar/tmp/iftop-ipv6-backports/ (for Debian 5.0 "Lenny"). Many thanks for your work so far, Mats! Best regards, Alexander

Even if you only have outgoing traffic only shown, it still sorts by the sum of incoming and outgoing, unless you hack the code as described below. I think ideally it would sort by what you have on screen, but that requires a slightly more complicated change to the sort function.

find upload hogs

i help running a small wireless mesh. altough our p2pfilters at gateway nodes are fairly acurate, we sometimes find people resorting to all kinds of tricks to circumvent those. to ease pinpointing villains, is there a way in iptraf to sort ip address by *upload* only? /gordon
