Re: [mpls-linux-devel] mpls linux crashing

[Pali <pal...@gm...>]

Hi Wind,
what I need now is to try L2VPN lab from mpls-tutorial and modify it. But
I'm still unsuccessful to build stable topology, because mpls linux routers
used to hang up / freeze. I have got also some kernel panic traces but it's
too difficult for me now to repair them.

Dear Wind Dong, please could You share how You run mpls v1.950?
I was trying to patch appropriate kernel 2.6.1.15 under debian 5.04, using
patch from:

*
http://switch.dl.sourceforge.net/sourceforge/mpls-linux/mpls-linux-1.950.tar.bz2
*

but compilation hang on a lot of errors, too many to correct them. I guess I
need older gcc then is in debian 5.04.

I also tried Fedora 10 i386 rpm from
*http://mpls-linux.sourceforge.net/fedora/10/i386/mpls*
but repeat same kernel panic as under Debian. So I guess:
- mpls v1.963 is unstable
- mpls v1.962 will I try now from RPM under FC10
*http://mpls-linux.sourceforge.net/fedora/8/i386/mpls*

Then I will try older versions from MPLS gitweb, I hope one will run
smoothly. On gitweb I can't see mpls v1.950

Does anybody has virtual machine with successful compiled mpls-linux? If
yes, could You please share it? I can provide online storage where to upload
it.

Thank to all who will respond.
