Dear Friends, I am using CENTOS 4.3 - kernel 2.6.9-42.0.2.EL with rkhunter version 1.2.8, but the rkhunter program show me problem on file /bin/kill. I compare files /bin/kill with other CENTOS 4 and it has same size. ====================== SHOE LOG =========================== Rootkit Hunter 1.2.8 is running Mon, 30 Oct 2006 12:56:44 -0200 Determining OS...

Thanks for help. Adriano Frare
