Lan configuration problem

vjta — Sun, 01 Jun 2008 06:58:10 GMT

Hi all!

I m facing one problem in my rx2660 server lan configuration.
When i reboots this server ip configuration changed & its not showing any interface in "netstat -nr" where as in my netconf file all entries are proper also its working when i configured manually thru SAM but settings lost once i reboot. I have removed all conf files form /etc/rc.config.d & this is contains only netconf file having 444 permition with root:sys .I tried for set_params addl also,but its not doing giving same problem.
I copied basic config file from /usr/newconfig/etc/rc.config.d also still problem persists.

regards
Vjta

the ownership of netconf file should be bin:bin

did you set the gateway address?

Why? All these are critical system initialization files.

Did you look in /etc/rc.log to see if there are any errors in the startup sequence?

Can you post the netconf file (without the comments)

hi Ttr

i hav removed only backup copies of netconf files from /etc/rc.config.d

then i copied fresh netconf file from /usr/neconfig/etc/rc.config.d/netconf

i also configured lan interface using set_params ip_address,gateway using set_params addl_network,at this stage my interface is up & accessible from network but the problem is after rebooting same interface is not accessible from network.
#ifconfig lanxx
ifconfig:no such interface

whereas netconf is showing same entries also net service is also running. in rc.log no error coming.

Post the netconf file.

According to the lanscan output the valid lan devices are lan0, 1, 5.

It has been a while since I played with those parts of HP-UX, but is it really ok to have backup copies of rc.config.d files in /etc/rc.config.d itself?

IIRC there is a boot time log - rc.log? - that may help shed light on what is happening. Perhaps it also gets copied into syslog.

Do NOT create "backup" copies in /etc/rc.config.d

During system boot the rc script parses every file in /etc/rc.config.d no matter what it is called.

Depending on the name of the backup file its contents will override others.

See man rc or read through any one of the /sbin/init.d/ boot scripts.
