Topic: [SOLVED] VPN connections stopped working.

[william_syd]

So I finally got the menu up and rebooted and it looks like the VPN connections are being accepted again. How does using the SMP kernel or the standard one have anything to do with VPN or PPTP connections...
Thanks for the help!

Your installed kernel modules have to match your running kernel.

You were running this kernel .... 2.6.9-34.0.2.EL but have this module installed.... kernel-module-ppp-1.0.2-2_2.6.9_42.0.2.EL

2.6.9-34.0.2.EL for one,
2.6.9_42.0.2.EL for the other.

So from this point forward reboots *SHOULD* go to the correct kernel? Can't I somehow remove the older kernels if I'm satisfied with the stability of the current one? Also, is it necessary to have the single and multiprocessor kernels on the machine?


Thanks!

How does using the SMP kernel or the standard one have anything to do with VPN or PPTP connections... and what would have caused my system to start booting into the standard kernel in the first place?

It doesn't.  You were using the 2.6.9-34.0.2 kernel and 2.6.9-42.0.2 modules.  The module version must match the kernel or those modules won't work with that kernel.

When the kernel is updated it installs the newer kernel and leaves the old one in case the newer one won't work.  It however updates the modules and erases the older ones and sometimes during the update grub does not select the correct kernel so it loads the old kernel that won't work with the newer modules.

I see. So should I delete old kernels manually to help prevent this or could that cause potential future problems?

Each new kernel is installed. Thats why you have more than one kernel version.

Kernel modules are upgrade. Thats why you only have the newest one.

What happened to you should not happen.

While your system is now working, someone else my suffer the same problem. To help avoid this, you should report this issue in the Bug Tracker.

This is a known issue.  There are a couple of bug reports discussing the best way to handle kernel and kernel module updates.
