Hi,
I am trying to enable NFS Server on my suse 12.2 with kernel 4.4.103-92.53-default
After following the guide: https://www.suse.com/documentation/s...fs-server.html
When trying to showmount -e IP from remote CentOS machine to the Suse, I receive error: clnt_create: RPC: Program not registered

This means the nfs server is not working well,
This is the log i receive when I systemctl start nfs-server:
linux-7mqw:/home/ilan # systemctl start nfs-server
A dependency job for nfs-server.service failed. See 'journalctl -xe' for details.
linux-7mqw:/home/ilan #

output of journalctl -xe:
