I'm looking for the problem, but why you have redhat 5.1 and kernel 2.0.30?

Note that I am running kernel 2.0.34 and the nettools was compiled under 2.0.30.  
I my system has been up for months and these errors just recently started to appear.  I only remember adding shadow passwords.  A new ssh shell. Thats about it beside web stuff.

I'm using 2.0.34 and netstat 1.33 BUT compiled under 2.0.32... I'm afraid of a library problem... Why don't you try downloading from contrib net-tools-1.432-2.i386.rpm I'm using it in another box without problems...
