Netconf problem

[ahmtoukhy]

Dears,
I have an issue with my system as I added some static routes to the system using #route add
But I need to make these routes permrnant so I added them in /etc/rc.config.d/netconf but still each time I restart the system all routes are gone !! what could be the problem?
attached the netconf file from server

[Mel Burslan · Accepted solution]

Try moving the IP address assignments block at the bottom of the netconf file to the top, definitely above the static route settings.

Also post a copy of the /etc/rc.log, especially the portion where the route activation fails. But I am pretty sure that, the failure is because of the interfaces not being active prior to the static route assignments.

[ahmtoukhy]

Actually the routes are assigned after the enabling of the interfaces as they were working when I used the route add command
But I will try your suggestion tonight and get back to u

[Patrick Wallek]

The way the routes were assigned with the 'route add' command is irrelevant to how they will be assigned when the system boots.

Doing a 'route add' from the command prompt does nothing to make them permanent and has no impact on the netconf file.

Mel's comment makes perfect sense.

[Mel Burslan]

If you have a system, on which you are happy with the routing, you can use a little script I developed to make a dynamically created routing table (i.e., using 'route add ...' commands) permanent. you can use it if you wish. I am attaching the script to this post. Hope it helps. It works for me but exercise caution and backup your netconf file, just in case

Hi,

Try using "set_parms initial", to configure the network settings and reboot the system.

your system will be brought up with the newer settings.

Thanks
Shiv

Hi there,

Try not to create the backup of netconf on /etc/rc.config.d, create the backup of netconf to your home directory or on /tmp directory.

Regards,
Adi.

Adi,

The issue you are referring to has been addressed in earlier versions of hpux and to the best that I know, having netconf backups in /etc/rc.config.d directory does not have any effect on networking any more, not on 11.x versions at least. It may be a good habit of housekeeping, but to each his own.

[ahmtoukhy]

dears,

thanks very much for your replies But still problem isn't solved I moved the routes in the file to the end of the file after interfaces declaration
the Backup of netconf is in /tmp
It suppose to be very easy and simple just add the routes in netconf and they will be permanent and I did it before on other servers
what seems to be the problem??

[Patrick Wallek]

Have a look in /etc/rc.log and see if there are any errors about network configuration there.

[Mel Burslan]

please post your new version of your netconf file contents in a post here (just copy-and-paste, attachments are hassle) Most probably there is a typo or something. This is not rocket science and should work if typed correctly.

[ahmtoukhy]

from /etc/rc.log it states very clearly that it couldn't add the route as interface isn't up try to add route after interface is initialized
this is the o/p even after I moved all the routes at the end of the netconf file(after interfaces declearion)and when I use route add it works fine!! ifconfig all interfaces are up !

[Mel Burslan]

It definitely is the timing issue. I had them quite a lot before having to write the script attached to one of my previous posts. If you add your routes by route add, then remove all the static route information from your netconf file and run my script, it will place all your active routes ona proper order, as the system currently sees them (I am assuming when you do the route add process, you are getting to a working routing table configuration) and creates you a clean netconf file.

If you like you can post your netconf and I can take a look at it.

This is my netconf file after changing location of the routes

For a precaution, move your /etc/rc.config.d/netconf file some other place and put the attached file as your new netconf into this directory and reboot. If the same thing happens again, before manually adding these routes, run the following two commands and post the output here:

netstat -rnv
netstat -in

I noticed that your default route was at the end of the static routes, which might be causing your problems.

[Mel Burslan]

also in addition to the two commands above, please run

traceroute 200.1.202.63

and I noticed I forgot the attachment. here it is on this post

Dear Ahmtoukhy, Mel,

Did you manage to fix this issue?  We have exactly the same problem on one HP-UX B11.11 box...
