VLC installation caused problems with internet(?)

Hello.

I have just installed VLC 2.0.8 on Linux 3.7.10-1.16-desctop openSUSE 12.3 (Dartmouth)(x86_64) and KDE 4.10.5 "release 1". Player works perfectly, but since now zypper returns the following (the same as YaST) error:

linux-ykpz:~ # zypper se stardict
Download (curl) error for 'http://download.opensuse.org/distribution/12.3/repo/non-oss/content':
Error code: Connection failed
Error message: Could not resolve host: download.opensuse.org; Name or service not known

At the same time firefox has "problem with loading page". However I can ping any web site, so it is not a problem with internet connection.


Thanks.
