Yes, the problem occurs here too. Looks like there were changes in the used system-code. Looks like just interface change. Looks like it's necessary to patch the code. Maybe some of the bigger Linux-distributions or BSD-people might provide a patch? Or if someone from the users here may want to look at it? Not sure if I have the time - and if I have time, if I can fix it. But if nobody else fixes it during the next four weeks I may give it a try. (or maybe earlier, don't know)

Thanks for the new URL. I updated the PKGBUILD. This software is ages old, and seems not to be further developed? Some other tools with similar functionality are out there, if you look for newer tools. But trafshow is very convenient in usage, imho.

It seems the address http://fossies.org/linux/misc/trafshow-5.2.3.tgz no longer points to a tarball, which seems to exist here now: http://fossies.org/linux/misc/old/trafshow-5.2.3.tgz Seems to be an old version, though I am not familiar with trafshow's development nor do I see a newer version on fossies.org.

Thanks for the hint, zatricky. I seem to have crapped the PKGBUILD with the last change. I have corected it now and checked the package-file. Should work now. BTW: trafshow is also very old and it seems that develeopment stalled for longer time too; so I'm not sure if you will be happy with it. I didn't knew iftop so far and will try it also :-) So, thanks for your verbose comment :-))
