Eixa dokimasei to linneighborhood alla eixe duo meionekthmata:

  a) Den paizei se FreeBSD pou to h8ela, giati xrhsimopoiei to smbmount, enw
     ego h8ela na paiksei me to sharity-light pou exei to BSD mou.

  b) Den h8ela na kanei ola ta shares mount, alla mono auta pou tha tou po
     ego, kai me sugkekrimeno tropo sto disko.

     Auto den to ekane otan to eixa dokimasei (h den to brhka egw).  Opote
     katefuga stin lush `script the hell out of it's ass', kai ekana auto pou
     peirgrafetai parakato :-)

Exo ena topiko lan opou ta shares pou kanoun ta mhxanhmata einai kurios gia
logous backup.  Gia na pairno backup ta Windows PC xoris na kathomai se ena
ena jexorista na kano copy apo to explorer ta arxeia twn diskwn tous.

Sto BSD pou exei to rolo tou backup box uparxei to ejhs:

        # ls scripts
        mount_andreas           mount_giorgos           mount_eleni
        mount_yiannis           mount_zeus              mount_uranus
        mount.servers           mount.workstations      mount.all
        umount_andreas          umount_giorgos          umount_eleni
        umount_yiannis          umount_zeus             umount_uranus
        umount.servers          umount.workstations     umount.all

1) Ta mount_XXX script kanoun mount ta shares apo ena sugkekrimeno mhxanhma.
2) Ta mount.servers kai mount.workstations kanoun mount omades apo PC pou
   exoun ena sugkekrimeno `rolo'.
3) Ta umount_XXX to anapodo apo to antistoixo mount_XXX script.
4) Ta umount.XXX to anapodo apo to antistoixo mount.XXX script.

Auta kanoun mount akribws oti xreiazetai.  An to mhxanhma pou theloun na
kanoun mount einai down, to agnooun kai sunexizoun.  H `gnwsh' tou poio
mhxanhma exei poio share einai kommati tou script pou kanei mount ta shares
tou sugkekrimenou mhxanhmatos.

Nai katalabaino oti kapoios tha frikarei tora "ma ekatse kai egrapse custom
scripts gia na kanei mount/umount. einai trelllooooos?"

Etsi omws ginetai mount akribws oti thelw ego, kai ta passwords pou einai
sta scripts tou /samba/scripts den einai anagkh na ta dino ekeinh th stigmh
(profanws ta permissions epitrepoun mono sto `root' na dei ta arxeia tou
/samba/scripts).  Ase pou ta pio polla script einai copy/paste enos basikou
script, pou apla allazo ta onomata twn shares kai ta password kai to kano
rename sto katallhlo onoma (enhmerwnontas kai ta mount.XXX kai umount.XXX
scripts katallhla ennoeitai).

Ena mikro paradeigma tou giati ena tetoio setup.  Ma ti sto kalo na to kanei
pou kanei mount ta mhxanhmata me Samba, me ta dika tou scripts?

Etsi ena aplo crontab entry mporei na kanei pragmata opws:

        cd /samba
        sh scripts/mount.workstations || {
           # some workstations not mounted
           echo "Some workstations failed to mount.  Aborting."
           exit 1
        }

        # Pame me to kanoniko backup twra.
        cd /samba/uranus/f/backup
        cd /samba/giorgos/drives
        tar cvf - "c:" | gzip -9c - \
          > /samba/uranus/drives/f/backup/giorgos.drive.c.`date +"%Y.%m.%d.%H.%M"`tar.gz
        ...
        kai ta loipa...

Kai na exei sto backup disko tou uranus ena arxeio pou onomazetai
`giorgos.drive.c.2000.01.08.21.10.tar.gz' kai exei to backup tou diskou C: apo
to sugkekrimeno PC pou parthike stis 08/01/2000 wra 21:10.

Twra giati sas ta grafo auta tha mou peite.  Giati thelo na deikso pos an
