I have worked with Suse since version 7. I have just downloaded opensuse 11.1 and am trying to set up the network. I am putting in an IP adddress of 10.30.30.23 and a subnet mask of 255.255.0.0, with a gateway of 10.30.30.1. However the network does not work. Pings give host unreachable messages. The problem is, whenever I go back into the network settings, the subnet mask I entered has been replaced with /16. If I enter a subnet mask of 255.255.255.0, next time in it displays as /24. (I can see a pattern here!) So no wonder is doesnt work.
Am I doing something wrong? Or is this a problem in 11.1?
/16 for 255.255.0.0 is correct and /24 for 255.255.255.0 is also correct.
However, Yast shows in the dotted decimal format only. Are you really seeing them through the Yast tool?
Yast can, and in 11 does, show the /16 or /24 notation at times and that
is fine. SLED and SLES 11 also do this and it’s fine. What is weird,
though, is that you had /16 in the first place. I’d be highly suspicious
of any network where the subnet mask was that high for end users. Maybe
it’s your own internal network and you only have a couple boxes on it but
that still seems a bit excessive. It may be that your home router/modem
doesn’t particularly care for that setting, especially if it is using one
of the 10-net addresses already on its other interface.
Good luck.
