Hi Craig,
Still have not determined the cause of the hostname becoming set. My
suspicion now is that it might be DHCP. I have now reset the hostname by
setting up the /etc/hostname file then running "hostname -F /etc/hostname".
I wish I could have determined the cause of this but if what I have done is
permanent then I will live with that.
Thank you again for your help.
Fennix
PS: Thank you to kalinux as well for your suggestion. The avahi daemon was
running so I have stopped that service (since it definitely is unnecessary)
but after rebooting I still did have the bogon hostname for my system. I
have overridden the name using the hostname command and making a hostname
file.

I'm thinking that the name must be coming from your dhcp server or from<br>
the config file for the network adaptor...<br>
<br>
what is output of?<br>
grep HOST /etc/sysconfig/network-scripts/ifcfg-eth0<br>
<br>
what is providing DHCP to this system?<br>

</font></blockquote></div><br><br>Hi Craig,<br><br>Still have not determined the \
cause of the hostname becoming set. My suspicion now is that it might be \
DHCP. I have now reset the hostname by setting up the /etc/hostname file then \
running "hostname -F /etc/hostname". I wish I could have determined \
the cause of this but if what I have done is permanent then I will live with \
that.<br> Thank you again for your help.<br><br>Fennix<br><br>PS: Thank \
you to kalinux as well for your suggestion. The avahi daemon was running so I \
have stopped that service (since it definitely is unnecessary) but after rebooting I \
still did have the bogon hostname for my system. I have overridden the name \
using the hostname command and making a hostname file.<br>
