Hi, I disbled SELinux when I installed the machines: SELinux: Initializing. SELinux: Starting in permissive mode selinux_register_security: Registering secondary module capability SELinux: Registering netfilter hooks SELinux: Disabled at runtime.

I've been doing this as part of the standard install process - removing all unnecessary packages and services. The only network service running is SSH - this is the same as on the FC1 boxes. chkconfig --list on the FC3 box is as follows: [EMAIL PROTECTED] ~]# chkconfig --list crond 0:off 1:off 2:on 3:on 4:on 5:on 6:off smartd 0:off 1:off 2:on 3:on 4:on 5:on 6:off irqbalance 0:off 1:off 2:off 3:on 4:on 5:on 6:off atd 0:off 1:off 2:off 3:on 4:on 5:on 6:off netfs 0:off 1:off 2:off 3:on 4:on 5:on 6:off sysstat 0:off 1:on 2:on 3:on 4:on 5:on 6:off acpid 0:off 1:off 2:off 3:on 4:on 5:on 6:off saslauthd 0:off 1:off 2:off 3:off 4:off 5:off 6:off yum 0:off 1:off 2:off 3:off 4:off 5:off 6:off cpuspeed 0:off 1:on 2:on 3:on 4:on 5:on 6:off network 0:off 1:off 2:on 3:on 4:on 5:on 6:off sshd 0:off 1:off 2:on 3:on 4:on 5:on 6:off iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off haldaemon 0:off 1:off 2:off 3:on 4:on 5:on 6:off netplugd 0:off 1:off 2:off 3:off 4:off 5:off 6:off readahead 0:off 1:off 2:off 3:off 4:off 5:on 6:off rhnsd 0:off 1:off 2:off 3:on 4:on 5:on 6:off microcode_ctl 0:off 1:off 2:off 3:off 4:off 5:off 6:off gpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off readahead_early 0:off 1:off 2:off 3:off 4:off 5:on 6:off messagebus 0:off 1:off 2:off 3:on 4:on 5:on 6:off kudzu 0:off 1:off 2:off 3:on 4:on 5:on 6:off syslog 0:off 1:off 2:on 3:on 4:on 5:on 6:off ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off autofs 0:off 1:off 2:off 3:on 4:on 5:on 6:off psacct 0:off 1:off 2:off 3:off 4:off 5:off 6:off [EMAIL PROTECTED] ~]# Any further advice would be appreciated, before I take the next step and compile my own Perl.
