I don't have this problem but this has been discussed many times on the SuSE
mailing lists and there are solutions. Don't know what distro you are running
but it probably would be handled the same way.
Try and do a search at http://marc.theaimsgroup.com
Also, Google is your friend!
Try something like:
site:lists.suse.com SLE (year) (subject)
Or, search the list archives on google with:
site:list.suse.com <arg1> <arg2> <arg3> ...
Each additional arg will help narrow the search. If you add [SLE] as an
arg it will keep the search to the suse linux-e list. At least that has been
my experience.
Good Luck, the answer is there and if I remember correctly it was not that
complicated.
