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.

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.

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