hostname is unknown

Andrew_80 — Sun, 19 Jan 2003 08:17:55 GMT

This is a new server and the hostname command is "unknown"
The /etc/rc.log has this error
Setting hostname
Output from "/sbin/rc1.d/S320hostname start":
----------------------------
unknown
usage: uname [-amnrsvil] [-S nodename]
EXIT CODE: 1
"/sbin/rc1.d/S320hostname start" FAILED
and if I try it from command line : root@terra01# /sbin/rc1.d/S320hostname start
unknown
usage: uname [-amnrsvil] [-S nodename]
EXIT CODE: 1

the strange thing is there is an entry in /etc/rc.config.d/netconf
HOSTNAME="terra01"
OPERATING_SYSTEM=-t
LOOPBACK_ADDRESS=127.0.0.1

and everytime I change the OPERATING_SYSTEM to HP-UX and I run the start command it change it back to "-t" I don't know why ???

I tried set_parms hostname twice and the same problem persist. and tried uname -S 'hostname'

Any ideas ? Thank you

I've seen strange behavior like this if there is an error in /etc/rc.config.d/netconf

Make sure all the entries are correct.

I've also seen the OS freak becuase the hostname was longer than 8 characters, which does not appear to be the case here.

I pulled a few old posts for you that have your exact message in them.

I read some of them and you might get lucky.

Hi

i think that mybe your /etc/rc.config.d/netconf file is not good .

rename the file to netconf.orig , copy a new file from /usr/newconfig/etc/rc.config.d/netconf to /etc/rc.config.d/netconf

the value need to be like this :

HOSTNAME=""
OPERATING_SYSTEM=HP-UX
LOOPBACK_ADDRESS=

remember also to put the param about the lan and the router .

and try to reboot the system .

i didnt found any docs on this issue .

if it will not work can you give us the netconf file for exam.

also check that the /etc/hosts is config correctly .

Hi,

Try using /sbin/set_parms and make sure the hostname is properly set. After this, reboot your system.

Also you can check and make sure the /sbin/init.d/hostname exists correctly.

Rgds.

Hi Andrew

OPERATING_SYSTEM=-t

That entry "-t" is weird. It should be "HP-UX".

Change it and run "/sbin/init.d/hostname start"

I feel the problem should be with the uname unable to retrieve the hostname for the system.

check doing a
#uname -n

check it gives the proper hostname.If it doesn't then

Just do a
#uname -S

Hi,

Hostname in /etc/rc.config.d/netconf and /etc/hosts files must be the same.
The OPERATING_SYSTEM flag in netconf must be HP-UX, whereas you have -t.

From prompt also you can specify hostname
#hostname=terra01,
but this will be a temporary.

Actually the problem was that the /etc/rc.config script corrupted Once it was replaced with a good copy, it worked fine.

Thanks for all of your help

My initial guess would be that someone edited the S320hostname script and botched it, but as others have noted the "-t" in OPERATING_SYSTEM is rather strange looking, so perhaps the botch is scribbling onto netconf.

Also, a minor but important distinction. The uname command does not set the "Internet" hostname of a system, it sets the UUCP "hostname" of a system.

The Internet hostname of a system is manipulated via the hostname command.

The UUCP namespace and the Internet namespace have rather different constraints on hostnames - for exmaple, their length. While both are being set (iirc) in the S320hostname script, applications should not "mix and match" them - if the app/script is going to do "things Internet" it should use the hostname command, not uname.
