Problems with linuxconf changes

[John Blankenship <johnb scripps edu>]

I have a new Dell workstation with Redhat Linux 6.2 installed. To date,
configuration via linuxconf has been easy, but when I later (today)
decided to configure samba via linuxconf, linuxconf underwent a
segmentation fault.

Restarting linuxconf brought up a message that the changes were not
implemented yet. Clicking on activate changes executed them, but did not
remove the need to have them changed.

Ditto for using netconf --update or linuxconf --update from the command
line.

netconf --status or linuxconf --status reveals:
----
List of things required to activate current configuration
    Executing: /etc/rc.d/rc5.d/S10network reload
    Executing: /etc/rc.d/rc5.d/S16apmd start
----

running ~/network probe reveals:
reload

Manually stopping, then restarting ~/network is not working, which would
seem to be what is recommended from the linuxconf website. (Or reloading,
etc).

looking at /var/log/messages reveals:
Jun  2 15:26:06 thiol sysctl: net.ipv4.ip_forward = 0
Jun  2 15:26:06 thiol sysctl: net.ipv4.conf.all.rp_filter = 1
Jun  2 15:26:06 thiol sysctl: net.ipv4.ip_always_defrag = 0
Jun  2 15:26:06 thiol sysctl: kernel.sysrq = 0
Jun  2 15:26:06 thiol network: Setting network parameters succeeded
Jun  2 15:26:06 thiol ifup: SIOCADDRT: Network is unreachable
Jun  2 15:26:06 thiol network: Bringing up interface lo succeeded
Jun  2 15:26:06 thiol network: Bringing up interface eth0 succeeded

I suspect my problems are due to not configuring something (hence the ifup
message) to do with the network when I configured samba. Can anyone help?

Thanks,
