Note: hostname can not have any section (between periods) that is more than 8 characters.

This appears to be a problem with the inetd daemon.

check /etc/inetd.conf

inetd -k
inetd -c

Hi,

Pls find the following output.

unknown:root:/#hostname
lcsweb6 ((not more than 8 char.)

unknown:root:/#inetd -k
unknown:root:/#inetd -c
inetd: There is no inetd running

How to change the hostname from unknown to lcsweb6

Hi SUresh,

1. Try pinging lcsweb6 ...see if it works.
2. Check root users .profile and /etc/profile
3. Use /sbin/init.d/inetd stop|start to stop and start inetd daemon.

If still it doesn't work then use:

4. Confirm entries in /etc/hosts are correct and execute:
# set_parms hostname

But this will reboot the system and you will see your hostname back after reboot.

Hope that helps.
Regards,

Hi Bharat,

Pinging is ok.

i tried to start the inetd in console, iam getting the following error
/sbin/init.d/inetd (36):/etc/ntp.conf is not identifier.But inetd command is working.
I checked host name is lcsweb6 and i checked uname -m , it displayed "unknown, then i used uname -S lcsweb6.After restart "uname" command output is unknown

Suresh

Suresh,

1. Use # set_parms hostname
for changing hostname permanently and reboot the system. I hope this should work.
2. Check /etc/nsswitch.conf file if it is present.
3. Check if your /etc/inetd.conf file is correct and see you do not have any backup file of inetd.conf in /etc. if it is there move it to some other directory.
Becuase during system startup all files in the /etc directory are read.

Regards,

Hi Suresh,

# cd /etc/rc.config.d
# grep HOSTNAME *
Check if there is a backup file of the netconf configuration, if so move it to the /tmp dir.
Double check the netconf file for errors.

HOSTNAME="lcsweb6"
LOOPBACK_ADDRESS=127.0.0.1
IP_ADDRESS[0]=X.XX.XX.XXX

Check you /etc/hosts file

127.0.0.1 localhost loopback
X.XX.XX.XXX lcsweb6

Check you /etc/nsswitch.conf should include
hosts: files

If you have changed the netconf file hostname /ip make shure to reboot.
