[opensuse] Can't ping to another computer on local net

I can ping from c2 to c3 on my local switch-connected net. I cannot ping from c3 to c2. Nfs is disabled on c3. If that is my problem, how do I enable nfs? Thanks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
