Hi, (sorry if my english is bad) I have the Slackware 13 kernel-current(18.104.22.168-smp), and i reach the total nessus installation, but with so much problems. I'll write something to help someone using newest Slack or similar.
i have an sucessufully installation with this packages: SERVER- nessus-server-2.2.9-1.fc4.i386.tgz (Fedora4package)
but i have an SERIOUS problem with the client installation, so i download the Slackbuild nessus-client 1.0.2, wich created /tmp/nessus-client-1.0.2-i486-2sl.tgz ,wich added NessusClient to /usr/bin. I think that's is possible install one nessus-client more recent, but didn't yet. i hope this help somebody-someone.
