ifconfig: socket: Host is down

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?

Re: ifconfig: socket: Host is down

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

Re: ifconfig: socket: Host is down

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

Re: ifconfig: socket: Host is down

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.

Re: ifconfig: socket: Host is down

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.

Re: ifconfig: socket: Host is down

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":
----------------------------
Boot time cleanup of /etc/ifconfig.muxids completed.
fopen: No such file or directory

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

What needed that and why?

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)?

Re: ifconfig: socket: Host is down

Hello, I am facing the same problem again, and the last time I could not answer and decided to reinstall the server.

Even today he remained in production normally, but the short time he left to accept telnet or ssh connections and then we made a console access over the LAN and restarted the server and when I was loading the network, the message appeared again: ifconfig: host is down.

Has anyone gone through this problem since then? Thank you.

Vérifier d'abord si par hasard vous n'auriez pas booté en init 1 (/etc/inittab)

and

# lsdev |grep 63
and

# lsdev -h -d tcp
