I had to make a few changes to your script. su-ing to root on my system

Guessing you did a su root
not a su - root :(


Here is the output.

I recommend you turn that service off, can cause slow DNS lookups. Command:
service avahi-daemon stop
chkconfig avahi-daemon off

======== hostname ==========
localhost

I recommand a Fully Qualifed Domain Name (FQDN) for your node.
Local web, email servers and whatnot like a FQDN name.

Example with suggestion:
darkstar.mylan.invalid

The .invalid will help external email filters to drop any email that
might escape your system.

Thar she blows, no default gateway route, see my example

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 10 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 10 0 0 eth0

0.0.0.0 192.168.2.1 0.0.0.0 UG 10 0 0 eth0

line with UG Flags is default route line.


Your resolv.conf indicates dhclient so for some reason your
/sbin/dhclient-script did not set the gateway.

Also, your mods to my script did not show your
/etc/sysconfig/network-scripts/ifcfg-eth* settings.

I did get fc5 installed today and my scipt works :)

If you changed eth0 to static, that would explain what is going on.
You would have to add a gateway ip to /etc/sysconfig/network


======== /etc/sysconfig/network ==========
NETWORKING=yes
HOSTNAME=

There is where you can set FQDN node.domain used during cold start and
read by other scripts sourcing /etc/sysconfig/network

$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=wb1.home.invalid <===== there is mine
GATEWAY=192.168.2.1 <=== gateway on my lan since eth0 is static setup

============== /etc/hosts ===============
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost

You also might set the FQDN here

$ head -3 /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 wb1.home.invalid wb1 localhost.localdomain localhost


It also looked for something that wasn't there and spat out this.

cat: /etc/version: No such file or directory

Yeah, that is a Mandriva Linux file. I fixed the script to manage it.
I re-installed fc5 at noon and found that bug.

Now when you make a hostname change, I recommend a reboot so all
services/deamons get the new host name.
