Limitation of eight (8) characters for nodename.

The limitation of eight characters in HP-UX for the nodename is problem that needs to resolved. I do not have this problem with Solaris. Is this ever going to get fixed?

I agree with you! It is an enhancement that HP definitely needs to look at. The thing to do, is to see if you can get it submitted as an enhancement request through the Response Center.

I'm affraid I agree ..... however if you contact the Response Centre ... quote JAGaa12274 & JAGad42350 at them to make life easier for them.

The HP CERTIFIED book under chapter 13 says the maximum length of the hostname on HP-UX 11 is "64 characters maximum". (pages 240 and 234)

Yes Edward, The system can have a nodename of more than 8 characters! But the problem is uname drops anything/everything after the 8th character. Now, that creates problems :)

Re: Limitation of eight (8) characters for nodename.

Here's a thread that gives some good reasons why it's not good to make it more than 8 characters:

But I agree...it will be much easier when we can go above the 8 character constraint.

Actually, there is a workaround. Edit the netconf file in /etc/rc.config.d and where HOSTNAME=<8charname>

add a new line with:
NODENAME=

Now the network name is long but the uname name is short as required.
