Hostname problem

[Alan Vargas]

Hello

I have a big problem with thist problem, when i type hostname command in a hp-ux server appear another ip address, this ip address does not belong to this server.

Thanks for your help

Hi Alan,

Could you please show an output of the command.

Hostname usually gives name, not IP.
In any case, check the following files:
/etc/hosts, /etc/rc.config.d/netconf,
/etc/nsswitch.conf.
Also please check yor name resolution (DNS,NIS).

Hi,

Agree with Victor that your question is a bit confusing. If you mean that by typing hostname it shows the name of a server whose IP is other than this server then you can check the hostname set in /etc/rc.config.d/netconf file & entry for the same name in /etc/hosts.

/etc/nssswitch.conf will let you know how the name resolution is taking place.

HTH,
Devender

can you clarify for us ? you type:

$ hostname

and you get back an IP address ?

can you type:

$ uname -a

does this return an IP address also ?

I don't believe this is true, for the hostname might truncate the length to 8 characters on the output..

what explan can you show us ?

thanks

you can set it by one of two way
1, issue this command
#hostname name_that_you_want
2, edit //etc/rc.config.d/netconf
HOSTNAME="server" #change it
OPERATING_SYSTEM=HP-UX
LOOPBACK_ADDRESS=127.0.0.1
save, exit and then issue two more commands
[server:/sbin/init.d] /sbin/init.d/net stop
[server:/sbin/init.d] /sbin/init.d/net start

Alan,
Nguyen Anh, did mention that you can set the 'hostname' by running the hostname command. so, my point was, maybe someone did this command:

# hostname

Thank again

Hello

I have this problem with the HP-UX server, when i typed uname -a i got the right name of the server, but when i try with hostaname those name does not match, the name must be tgt20, and whe i try to list or install any aplication o patch i got this error:

-all:[P0]/>swlist
# Initializing...
# Contacting target "-all"...
ERROR: Could not contact host "-all". Make sure the hostname is
correct and an absolute pathname is specified (beginning with
"/").
ERROR: More information may be found in the daemon logfile on this
target (default location is -all:/var/adm/sw/swagentd.log).
-all:[P0]/>

Attached the other command:


-all:[P0]/>uname -a
HP-UX tgt20 B.11.11 U 9000/800 2964193283 unlimited-user license

-all:[P0]/>hostname
-all
-all:[P0]/>

I´d like to know how to fix this error without boot the server.


Thanks again

Simply do:

# hostname tgt20


You really need to figure out how the hostname is getting reset. I would guess that someone that doesn't know what they are doing, is using the hostname command incorrectly.

[Mel Burslan]

what is the output to the 'hostname' command ?
that might tell you something.

also check if somebody messed up with the /sbin/init.d/hostname script. I have seen stranger things happen by some people with good intentions and bad knowledge, modifying the startup scripts.

It´s works .. thanks again gu
