KNOWN ISSUES

RedHat 7.2:

There is a bug in the version of ncurses distibuted with RedHat 7.2 that will cause iftop to segfault. The RPM in RedHat's Rawhide distribution fixes this.

Slackware 8.1:

You may need to upgrade your libpcap (by updating the tcpdump package) in order to compile iftop.

FreeBSD 4.7:

This version of FreeBSD lacks a proper gethostbyaddr_r function. You should choose an alternative name resolution technique using the --with-resolver=... option to configure.

Solaris:

On Solaris, iftop has to run in promiscuous mode in order to capture outgoing packets. iftop autoconfigures to run in promiscuous mode on Solaris, but will filter out non-broadcast packets which are not addressed to or from localhost. On Solaris, the -p option merely disables that filter.

If you have some other sort of system that behaves like Solaris in needing promiscuous mode, you can pass --enable-default-promiscuous to configure to enable this behavior.

Cf. http://www.tcpdump.org/lists/workers/2002/02/msg00010.html

The version of curses distributed with Solaris may not be sufficient for iftop's needs. You will probably need ncurses or similar.
