To access the scantech redmine site using our ssh access:
ssh -L 4444:192.137.81.1:443 -p 8400 mail.scantech-id.com
now connect from your browser using: https://localhost:4444/

Get ssh access to my PC at work (panoramix)
find ip of panoramix with avahi-browse -r -a on verci (here 192.137.81.113)

Make ssh tunnel to panoramix:
ssh -L 3333:192.137.81.113:22 -p 8400 mail.scantech-id.com

All distro releases have bugs – including openSUSE, many of which will of course be fixed via online updates in the coming weeks and months. However so far I’m not aware of any major bugs that will cause a lot of grief to legions of people.

I predict that the thing that will cause the most people to say “wtf!?!” in 11.2 is actually intended behaviour. YaST/zypper will not show nor perform updates that involve “vendor changes” (i.e. updating an official package to a newer version of the same software from packman) unless the user explicitly does some extra work.

You roughly have these coping strategies:

  • Don’t worry about it and stick with the old versions included in the distro no matter how many 3rd party repositories you add.
  • Manually go to the Repositories tab or the Versions tab in YaST Software Management, and manually select the updates you want – or manually specify the versions you want on the command line with zypper (note, you only have to do the extra work to change vendor once per package).
  • Set AllowVendorChange = true in /etc/zypp/zypp.conf – this way YaST/zypper will update everything to whatever has the highest version number – and let you ping-pong back and forth between package vendors, if that’s what you want.

In the future the tools are expected to be improved, so that the vendor stickyness becomes less annoying and obtrusive.
