lan problem

[Arockia Jegan]

I have v-class system running HP-UX 11.11. I installed the latest bundles GOLDBASE11i and GOLDAPPS11i. When the system got rebooted after the bundles installation the system was not in the network. When i typed "ifconfig lanx" system shows lanx is up. But it's not up. But when i bring down the lanx and bring up lanx then it's working fine. How can I solve this problem?

Is the server answering pings from other devices?

What is the outout from a netstat -rn?

What is the results of a lanscan?

Check /etc/rc.log for that particular LAN startup and if erros were found post them here.

There are no error messages in /etc/rc.log files. I'm not able to ping the system from remote

Apart from the /etc/rc.log as mentioned, verify the /etc/hosts file for system name.
Then check the /etc/rc.config.d/netconf file for correct syntax of the ifconfig command.

I have seen problems where ifconfig does not work with ifconfig hosts_alias
where the hosts_alias apparently should lookup /etc/hosts.

There is probably some nsswitch.conf problem in DNS -> hosts lookup order problem.

I'd start by correcting all occurances of ifconfig in your /etc/rc.config.d/netconf

hi,

recheck the /etc/rc.config.d/netconf file
and make sure the lan interfaces are in sequence and right order.

I had a look at the netconf file. I have 4 lan interfaces in that system. The netconf file has the configuration info for all the 4 lan interfaces.
But the INTERFACE_STATE is up for only lan1. When I removed the config details of all interfaces other than lan1 , it's working. But it worked fine earlier with out removing this entries.

[Ron Kinner]

In your netconf are you using a different index number for each interface? Double check. It's easy to copy the lines you need then forget to change one of the index numbers.

Have you stored any old versions of the file netconf in the same directory. Try moving them out to a different location.

Hi,

Check the network card configuration with SAM. You can find any mismatches from the SAM menu. Check for any config clashes there.

Make sure that you are using unique index ids for different lan cards.

each lan inetrfaces have different indexes. But same IP address is assigned to all lan adapters. But INTERFACE_STATUS is enabled (UP) for only one lan interface

[Ron Kinner]

I think that's the problem. It sees a conflict with the IP addresses all being the same. If you must do this try putting the lan you want active as either the first or the last in the netconf. I expect the first position will do it since it will read it first and set it up then go on to the next and go on to the next one and get mad because you have already used the ip address. Tho there is alwasy the chance that it will kill the previous one and thus only the last will work.
