The remote openSUSE host is missing a security update.
The NetworkManager configuration was too permissive and allowed any user to read secrets (CVE-2009-0365) or manipulate the configuration of other users (CVE-2009-0578). With the previous update PPP connections didn't work. This second update fixes that problem. Additionally a bug where wifi devices didn't work correctly when the machine was booted with killswitch turned on has been fixed. The automatic ethernet connection can now be edited and NetworkManager can now work without ModemManager.
