ifconfig: socket: Host is down

[Wilder Mellotto]

Hi, I have a problem with a HPUX 11.31 (rp4440).

I rebooted the server, and the message above appears:

ifconfig: socket: Host is down

I cant execute the /sbin/init.d/net start or ifconfig lan0 up

I don't have any clue to solve this problem, can anyone help me?

is the host still down or UP . if it is up you can check your lan cable if it is properly connected or not and also check your cable on the switch side as well.

if still you are facing the same prob than change you lan cable and try .

if agani you are facing the same issue send me the output of

/etc/rc.config.d/netconf

lanscan

netstat -in

Good Luck

Hi,
Do you see lan0 with lanscan?
what is the output of ioscan -fnkC lan?

What is displayed if you run "lanscan"?

What is displayed if you run "ifconfig lan0"?

Try "ifconfig lan0 plumb" first, then "ifconfig lan0 ". Does it work any better?

Look at /etc/rc.log. There might be other error messages related to this problem.

If you have a typo in your /etc/rc.config.d/* files, you may get a *lot* of error messages in /etc/rc.log. In that case, don't panic: just look at the first error message, find the typo, fix it and test again.

Sometimes missing a quote character or something like that can throw off the entire /etc/rc.config.d/* processing, causing a cascade of error messages. Fixing the typo that caused it makes all fine again.

Thanks a lot for all responses. I attached some outputs.

The server is down. I rebooted for a Timezone maintenence and this problem occurs. I tried runnng ifconfig in single user mode, but the same error occurs.

[Jupinder Bedi]

Now I can give some mor information, I checked my rc.log, please check this error:

Configure Loopback interfaces (lo0)
Output from "/sbin/rc2.d/S008net.init start":

I go to the script and the script call this command:

# /usr/bin/autopush -g -M 63 -m 0

My netconf is attached

What needed that and why?

[Wilder Mellotto]

To change my timezone. I add a new entry in /etc/TIMEZONE and /usr/lib/tztab.

The former may need a reboot but the latter doesn't.
Did you add a custom entry in tztab(4)?
