Another release for y'all to try:
http://www.ex-parrot.com/~pdw/iftop/download/iftop-0.15pre2.tar.gz
I've added config file support. The code for this was inspired (in the "cp config.{c,h} ~/cvs/iftop" sense of the word) by code from tpop3d. To make things easy, this stuff is totally undocumented, except for me saying:
cat > ~/.iftoprc interface: eth0 dns-resolution: yes use-bytes: no log-scale: yes max-bandwidth: 10M filter-code: not port 53 ^D
cfgfile.c may give further clues. I'll be documenting this properly for the 0.15 release and at some point I'll add the ability to dump the current configuration to a config file.
For your ease and convenience I have changed the letters bound to various options. Actually, this was an attempt at getting consistency between command-line options and run-time buttons.
Please let me know if it doesn't work.
