I have never used that command before. I use hostname. "domainname comes
up with the same results as you get on all of our servers. A "man
domainname" says this:
domainname - show or set the system's NIS/YP domain name
So I would say that if you are trying to show or set your system's NIS/YP
domain name, then just type "domainname bsaeg" to set it and then when you
type "domainname", it should give you what you are looking for. To get it
to come up when your machine boots, put the "domainname bsaeg" command in
your systems startup script. For mine I would put it in /etc/rc.d/rc.local
at the end with the following line:
/bin/domainname bsaeg

Hi Andrew. Type "domainname bsaeg", minus the quotes, at the command prompt
and see if your NIS clients can bind. You may have to stop and start ypbind
to accomplish this.
After that, run ypwhich to make sure you are communicating with the NIS
server.
Good luck.

Using one machine as an example it says none when i do type domainname it
should say bsaeg. Below are a few files if you see something wrong anybody
let me know. Also does anyone know how i can get the machines that have hung

How are these machine being set up? I usually don't worry about editing
the files individually and let "authconfig" handle that all for me.
For your hung machines, I'd boot in single-user-mode, disable ypbind
"chkconfig ypbind off", boot the rest of the way up and then verify the
config with "authconfig".

That's bizar. Red Hat AS 2.1
This is from dmesg:
# dmesg|grep eth0
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex
And this is from mii-tool:
# mii-tool eth0
eth0: negotiated 100baseTx-FD, link ok
Red Hat AS 2.1
Any idea?

Google suggests that the E1000 is not supported by mii-tool.
