For some time I have a problem with NFS share from other machine (there is probably different than PCLOS Linux).
My /etc/fstab looks like this:
192.168.1.142:/magazyn /home/kszyh/magazyn nfs users,nolock,soft,intr,rsize=8192,wsize=8192,nosuid 0 0
mount magazyn returns error:
mount.nfs: requested NFS version or transport protocol is not supported
Nobody else reported errors, so I think the problem is on my side.
