uname -n

[Charles Li_1]

Hi,
We are using HP-UX 11.11. When I issue uname -n, it return the servername without the full domain.
When I try the same command on Tru64 and Linux RH AS, it return server name with the full domain.
Is this what HP-UX suppose to return?
I am having problem with users accessing my server, I am think the server name without full domain might be the problem.

Thanks
Charles

Charles,

I suggest you take a serious look at the man page for uname. Go to the -n section and not the reference to the WARNINGS section. I'm not going to quote the whole thing here. Go take a look.

Please describe the problem you are having accessing the server.

Note that HP-UX does not support hostnames greater than 8 characters. You will have access issues if the hostname is greater than that. SD-UX will be VERY unhappy with that circumstance.

hostname returns the hostname

The hostname can be like his

server.yournet.org

It is contained in /etc/rc.config.d/netconf

Check the file /etc/nsswitch.conf to see how name resolution is working on your box.

Is your network using DNS? Are the entries for the HP-UX server correct in the DNS database?

As far as I know that is normal for HP-UX.

What kind of problem are your users having? Most likely the hostname of your HP-UX box has nothing to do with it. Are the users attempting to connect vi hostname or hostname.domain.com? What type of address lookup facility (DNS?) do you use? Is the hostname able to be resolved both ways (hostname and hostname.domain.com)?

I would suspect you name resolution method before I would suspect your HP-UX machine itself.

Pete,
Thanks for your reply.
I did look at the section that you refer me to.
+++++++++++++++++++++++++++++++++++++++++++++++
-n Display the node name (system name) by which the system is usually known in a UUCP network.
+++++++++++++++++++++++++++++++++++++++++++++++

Is the node name suppose to be without the domain?
ie. our server name is epic228 and the domain is dep.state.fl.us. When I issue hostname it return back epic228.dep.state.fl.us, but with uname -n, it only returns epic228. Is this the correct behavior? Or, is something not setup right on our server?
We would like both the hostname and uname -n to display server name with full domain.

Thanks
Charles

Charles,

Maybe this excerpt from the WARNINGS section will help:

+--------------+--------------+---------------+-----------------------+
|Node Name |Command |name Format |Used By |
+--------------+--------------+---------------+-----------------------+
|Internet name |hostname name |sys[.x.y.z...] |ARPA and NFS Services |
|UUCP name |uname -S name |sys |uucp, related programs |
+--------------+--------------+---------------+-------- --------------+

Charles,

Well, that didn't come out to legibly, but what it's saying is that "hostname" should return "sys.x.y.z" and "uname" should return "sys". This is consistent with the behaviour you're seeing and is correct for HP-UX.
