Exporting and NSS Volumes for NFS Access – OES11 to Linux.
Let say that you have OES11 machine with NSS volume and you would like to export this volume to Linux machine for sharing data.
To exporting and NSS Volume from an OES11 machine to a Linux machine, add the following to /etc/export on OES11 machine:
root# cat /etc/export
/media/nss/DATA/Shared/XXHR/BNMDEV1 Linux(fsid=1,rw,no_root_squash,sync,anonuid=1000,all_squash)
root#
To mount NSS volume from an OES11 machine into a Linux machine, add the following to /etc/fstab on Linux machine:
root# cat /etc/fstab
oes11:/media/nss/DATA/Shared/XXHR/BNMDEV1 /share/Shared/XXHR/BNMDEV1 nfs defaults 0 0
root#
to verity that everything is okay type mount command on a Linux machine, and you should see something like this:
root# mount
OES11:/media/nss/DATA/Shared/XXHR/BNMDEV1 on /share/Shared/XXHR/BNMDEV1 type nfs (rw,addr=172.16.12.12)
What is the maximum length of a valid email address?
That limit is a maximum of 64 characters (octets) in the “local part” (before the “@”) and a maximum of 255 characters (octets) in the domain part (after the “@”) for a total length of 320 characters. Systems that handle email should be prepared to process addresses which are that long, even though they are rarely encountered.

Starting NFS client services: sm-notify idmapd – hangs on SUSE and OES11.
The system is responding to a keyboard, but the booting process does not go forward.
Only ctrl+alt+del is working fine. To make it work I had to reboot with runlevel 1 and delete this one:
/etc/init.d/rc5.d/S04nfs.
After that system is booting without problem.
OpenVPN and OpenVZ tun issue.
After the upgrade Debian 7 to Debian 8 on OpenVZ platform on OVH the OpenVPN service stopped working. The problem was that the “TUN” device was missing, so the command below will temporary fix this problem.
root# mkdir -p /dev/net
root# mknod /dev/net/tun c 10 200
root# chmod 600 /dev/net/tun
Also you can add this to a script at start up.
