Ive installed portsentry on my fedora core 2 machine
...and there it all went wrong from the start. Uninstall it and install a proper IDS that's maintained, enhanced and supported by a huge community: Snort
. Portsentry was a good tool when nothing else was around, but it had it's flaws and Psionic didn't really maintain it much this millennium. Then it was bought by Cisco, then released on Sourceforge and now the last source date is 2003. Ditch it, don't waste time.
