Expanded Host Name
I am using HP-UX 11i v2 (June 2008 Media) on rx2660 itanium machine.
I want to assign hostname to machine which is 12 letter long.
I try following command but it is giving error
=======================================
# kctune expanded_node_host_names=1
ERROR: There are no tunables matching the name you specified.
=======================================
HP UX Manual says long hostname can be set through above mentioned command.
Please give suggestion about this.

Re: Expanded Host Name
u can have a look at the following that clearly says that the BUndle that i was earlier talking about must be installed on an 11iv2 system to enable that feature of long host names as u desire in this case.
have a look at this
http://docs.hp.com/en/5991-6469/ch09s13.html
so u gan go ahead and install the same downloading free from the site that i earlier have specified.
http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=NodeHostNameXpnd
after u download this to ur PC , upload using ftp this depot to the server in /tmp directory or somewhere in binary mode.
This is somewhat 274 MB in size.
and after that run a simple swinstall
#swinstall ├в s /tmp/
On a Standard basis HP says that u must understand the Impact of using the non-standard hostname as that poses compatibility issues with certain applications.
Regards
Sujit
do not forget assigning the points at least if u r helped by a post. Someone has spent time for u.

Re: Expanded Host Name
to which I would add that you won't find out *which* applications have problems with "long" names until you try to run them. I strongly recommend that you stick to the standard 8 character name

Re: Expanded Host Name
HOSTNAME="myhost"
For a long network name and a legal hostname (for uname), use both variables in the netconf file:
HOSTNAME="short"
NODENAME="longcomputername"
And you can add many additional names for the computer in /etc/hosts. As mentioned, adding the patch to your system can break applications, scripts and networking tools. The list would be very extensive, certainly not worth it to create an unstable environment.
