Topic: Uninstalling 5.6u4

[Dave Rozendal]

I upgraded to 5.6u4 last night and then lost my ability to connect to a vpn outside of my network.  I have not tried to connect to my vpn running on SME.

I was having no problems under 5.5 and would like to return to 5.5.  Is there a way I can uninstall the update that I applied last night?

Thanks

Dave

Did you also apply the VPN mppe mdules patch applicable to your server architecture ? You more than likely need to do this to get VPN working.

You may also need to change some settings in your VPN client setup
eg
check (ticK) Require data encryption.

My client VPN setting that worked OK for v5.5, did not allow a stable connection under v5.6, until I changed them.


If you really want to go back to v5.5 you will need to do a fresh install and restore from backup (which you have of course, don't you ?)

I downloaded the update for 5.6u4 from a mirror site and the executed:
    rpm -Uvh --replacepkgs *.rpm
    /sbin/e-smith/signal-event post-upgrade
    /sbin/e-smith/signal-event reboot

If there is a separate vpn mppe patch, I haven't found it mentioned before or seen it on a download site.  Where did you find it?

I have changed several combinations including the data encryption.  What I find odd is that I can't tunnel through my sme box into another vpn on the internet.  I haven't tried to vpn into my sme box yet since I haven't been able to hook up to another network.

Thanks for your help.

Dave,

If you are using XP Pro, some have found luck by removing and then reinstalling hotfix Q811493.  If it is not on your system, you need to install, remove, install.  

This helped my VPN out a lot....but it is not perfect.  I find that my SME 5.6 at home will allow a fast stable connection out from a given client on the lan.  Once I use vpn from another system.....things goto hell.  A reboot resets it and if I use VPN from a single system on the lan things are great.  When I mention another client using vpn, this is to the same SME server at work...so I don't know if it is the destination being the same or just another pptp client on a different lan ip address causing the problem.

I am also interested in the "mppe mdules patch" if this is something post U4.  The first pptp patch worked great, but U4 supposedly applies this patch.

Good luck,

ryan

I don't know where you are looking but I found it here first go !

http://www.ibiblio.org/pub/linux/distributions/e-smith/updates/5.6/Update4/RPMS/mppe/

If you are using Win XP SP1 I beleive there was a problem with the VPN client in that release. Better to uninstal the SP1 if you want VPN to work with XP. I have not checked recently to see if Microsoft have fixed the problem yet with a later SP.

The original readme does not appear at the ibiblio site so here it is (in part).

PPTP ppp-mppe kernel modules
----------------------------
The mppe sub-directory contains the mppe kernel modules for all kernel
architectures. The correct module is required to enable the PPTP server
to function.

The SME Server 5.6 CD only contains the i686 kernel variant.

To install the athlon specific kernel module, download
it and then run:

    rpm -Uvh --replacepkgs ppp-mppe-modules-2.4.2-4es.athlon.rpm
    /sbin/e-smith/signal-event post-upgrade
    /sbin/e-smith/signal-event reboot
