Topic: problems with the kernel 2.6.9-42.0.2.EL

[jmarcosm]

Hi,

I can´t connect with pptp to my sme 7 box. I checked the following:

In the logs: Oct 12 09:57:00 huilem pppd[4114]: MPPE required, but kernel has no support.

Then I perform:

uname -r
2.6.9-34.0.2.EL

also I check:

rpm -qa |grep ppp
ppp-2.4.3-7.rhel4.1
kernel-module-ppp-1.0.2-2_2.6.9_42.0.2.EL
kernel-smp-module-ppp-1.0.2-2_2.6.9_42.0.2.EL
rp-pppoe-3.5-22

Then I checked at the grub menu that I have the option of the kernel
2.6.9-42.0.2.EL , but if I load this kernel the system crash!

I can read the following:


Kernel panic -not syncing: attemted to kill init!
and the capslock and scroll lock led´s of the keyboard start to blink!!

Im not a linux expert so I really need a hand on this.

Thanks in advance

It appears your booting up using the Centos kernel, to change this on your next reboot when you see the white screen and a penguin logo press the down arrow key and you should see a SME Server EL kernel try selecting this one and all should boot up.

For each kernel the SME developers have to build some kernel modules to go with it. Your probably missing the ppp/pptp module to match your kernel.

You best option is to revert back as stated above to a previous kernel.

You can edit

Change default to the kernel you want. They count top to bottom starting at 0. The above is an example. Yours may be different.

[byte]

Your probably missing the ppp/pptp module to match your kernel.

If that is the case then a Bug Report should be opened, but I still think they are booting from a Centos kernel not one of the SME Server kernels. Because I've not seen we are up to 42.0.2 on the SME Server side unless I've been sleeping

42.0.2EL has been available in sme-testing for at least 6 weeks or more.

[william_syd]

2.6.9-34.0.2.EL

I think he is booting a smeupdates kernel.

Some sort half update has occured. We need more details like what repositories are enabled.

EDIT: JonB, where did your post come from. Anyway just confirming what you said.

I would suspect it was a yum update with sme-testing repository enabled but he didn't do a

signal-event post-upgrade
signal-event reboot

afterwards.

Jon

[william_syd]

That one..

Code: [Select]

signal-event post-upgrade; signal-event reboot

[JonB]

Correct, I was just about to edit my post and correct it. You beat me to it.

42.0.2EL has been available in sme-testing for at least 6 weeks or more.

OK I'm wake   Then this will need to be raised on the Bug Tracker if using the sme-testing repo.

[CharlieBrady]

2.6.9-34.0.2.EL

I think he is booting a smeupdates kernel.

Some sort half update has occured.

I don't think so. It's quite normal for old kernels to be left installed.

The key issue here is that the "correct" kernel (the one for which we have supplied PPTP support) supposedly crashes. Marcos should take that to the bug tracker, and will need to provide more detail about what he sees at the time of the crash.

[william_syd]

Did this make it into the bugtracker?
