How-To

SSH

  • Enable SSH service
  • To have root access, log in as user root, and use same password as admin account.

NFS

(See HOW-TO page here)

  • Enabled NFS service
  • Edited NFS privilege for share volume1/backup, allow rw, for client minimoy

Then from NFS client, tried 

$ sudo mkdir -p /net/mnemosyne/backup
$ sudo mount mnemosyne:/volume1/backup /net/mnemosyne/backup
mount.nfs: access denied by server while mounting mnemosyne:/volume1/backup

Looking into NAS file /var/log/messages (need to ssh as root on the NAS), there is the line: 

 ... refused mount request from HOST00245402988d.HELL for /volume1/backup (/): no export entry

So it seems that the connection is refused because the DNS name of the NFS client does not match the export line in file /etc/exports 

 /volume1/backup minimoy.HELL(rw,no_wdelay,no_root_squash,insecure_locks,anonuid=0,anongid=0)

Found a working recipe on this page:

  • Content of file /etc/exports
 /volume1/backup 172.19.100.102(rw,no_wdelay,no_root_squash,insecure_locks,anonuid=0,anongid=0)
  • Touched file /var/lib/nfs/rmtab (because non-existent), :
$ touch /var/lib/nfs/rmtab
$ cd /
$ /usr/sbin/exportfs -a            # Update list of exported filesystem
  • On NFS client, mount the NFS share with:
$ sudo mount mnemosyne:/volume1/backup /net/mnemosyne/backup

Open issues:

  • How to make it work using hostname instead of IP addess? Additional problem is that at each boot DNS Relay table on the ADSL router is reset to 'HOSTxxxxxxxxxxx' for wired interface on the NFS client, hence making it not recognizable for the NFS server.
  • How to deal with Access Control? I want root to be mapped to nobody, and write access only allowed for one user (which requires password to login)?
→ This can be done with the following export line:
 /volume1/backup minimoy.HELL(rw,no_wdelay,root_squash,insecure_locks)
