[Iftop-users] iftop-1.0pre2 doesn't resolve own ipv6 correctly
by Vladimir-M. Obelic 23 Apr '12

23 Apr '12

Just compiled the 1.0pre2 version (pre1 has missing counter_hash.h file). Apparently the resolver for ipv6 has a problem with resolving local host (do not confuse with localhost) own ipv6 address. I.e. Here the host where iftop is being run has ip6 addres 2001:470:b4a7::102 (amagi.gbit6.net) Iftop with dns resolution: amagi.intr.gbit6.net <=> cam.intr.gbit6.net yamato.gbit6.net <=> yamato.gbit6.net <http://pool-173-79-27-59.washdc.fios.verizon.net> same situation without dns resolution: 10.1.0.102 <=> 10.1.0.101 2001:470:b4a7::102 <=> 2001:470:b4a7::11 It's as if it wrongly uses the fqdn resolved for the remote host. Resolving of remote hosts that have ipv6 addr works properly. A simple mistake I guess? Regards Vladimir-M. Obelic

[Iftop-users] drawing bar scale with bandwidth_in_bytes option
by Stephen Hamer 03 Apr '12

The bar scale at the top of the window doesn't change units along with the bandwidth_in_bytes option. Given that the host bars change to be in bytes it seems reasonable for the scale to change as well. I've included the diff to make this change below.
