How-To

SSH

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

Samba

  • Need to specify explicitly utf8 as charset:
mount -t cifs //mnemosyne/photos /smb/mnemosyne/photos -o allow_utime=22,umask=002,noperm,iocharset=utf8

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 to 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)

Compile

Unison

Instruction from Tom Booschaert ([2]). Unfortunately although unison seems to run ok, it does not actually work. 

** install OCaml, Gnu C Compiler en Make:
ipkg install ocaml
ipkg install gcc
ipkg install make

** get Unison source and unpack:
mkdir Unison_tmp
cd Unison_tmp
wget http://www.seas.upenn.edu/~bcpierce/unison//download/releases/stable/unison-2.32.52.tar.gz
tar -xzf unison-2.32.52.tar.gz

** use make to compile:
cd unison-2.32.52
nano Makefile --> NATIVE=false
make UISTYLE=text

** copy executable to bin folder so it can be executed anywhere:
cp unison /bin/

** check
unison -help
