IP address Change

samir_24 — Mon, 19 Jul 2004 19:34:57 GMT

Hi All,
I have HP-UX 11.00 server with 4 lan interfaces, I changed an IP address of one of them.
the server become very slow and the telnet session take about 10 min. to open - (I telnet the server through another interface attached to my lan rather than the changed interface).
when I change back the old ip address of this interface , everything was OK.
can any one tell me why this problem happened.
Another Problem....
after reboot. non of the following network commands work !!!!

# sam
sh: sam: not found.
# lanadmin
sh: lanadmin: not found.
# ping
sh: ping: not found.
# ifconfig
sh: ifconfig: not found.

Can anyone Help ????

Thanks in Advance.

Hi,
First try to locate the lanadmin command with:

find / -name lanadmin -print

If it does not exist then somehow it is deleted.

Regards.

Another way you can use to change IP to your lan card is editing file /etc/rc.config.d/netconf
In this file you can also set default gw and other parameters for your lan card.
Then to apply changes do
/sbin/init.d/net stop; /sbin/init.d/net start
and check your netstat -nr otuput to see if it's all right.

Did you check the ping status of first changed IP-Address. It may be in use in your network. If you use that,it will bind that ip-address with other machine and try to send the send the data's to that ip-address.

Get the all ip-address in ur machine using netstat -in. You can use vsar command to view the performance rate of ip-address else use sar.

Second problem is because of user permission. We have to use default full path of system command as,

/usr/sbin/ifconfig lan0
/usr/sbin/ping

Before really trying to answer...Maybe it would be helpfule to know exactly what steps you did to change the IP ?
....cause your subsequent errors,if all you did was a simple IP change, are 'interesting'....

sam - not found?

Sounds like not all file systems are mounted...in particular /usr

sam is: /usr/sbin/sam

How are you changing the ip? is it lan0?
