Modification to software on Lothlorien and mirkwood

Installed new Debian-linux release codename Lenny. the old Linux partition is still available for booting

ssh-add is now done by the pam-ssh library at login so there is no more need for typing ssh-add and passwd to log to othyer machines.

pure-ftp server installed
SVN and CVS installed

On mirkwood I tried to make the launch of the astropci and spooler processes more robust through these two scripts:

#!/bin/sh
SERVICE='astropci_usr'

if ps ax | grep -v grep | grep $SERVICE > /dev/null
then
    echo "$SERVICE service running, everything is fine"
else
    echo "$SERVICE is not running"
    echo "start $SERVICE"
    sudo $SERVICE 60000
fi

exit 0

and:

/usr/local/bin/mirc_spooler

#!/bin/sh
SERVICE2='spooler'

if ps ax | grep -v grep | grep $SERVICE1 > /dev/null
then
    echo "$SERVICE1 service running"
    echo "start $SERVICE2"
    if ps -Uspooler | grep -v grep | grep $SERVICE2 > /dev/null
        then
            echo "$SERVICE2 service already running"
        else
            echo "start $SERVICE2"
            sudo -u spooler $SERVICE2
            kill -9 `pgrep $SERVICE2`

    fi
else
    echo "$SERVICE1 is not running: cannot start $SERVICE2"
    echo "start $SERVICE1 first !"
fi
exit 0

Also modified in /home/observer/.bashrc :

alias astropci="screen astropci"
alias spooler="screen mirc_spooler"

So that the server run inside screen and keep running even if ssh shell is killed

reduced timeout interval of sshd to 1 sec to kill the ssh client sessions as soon as there is a network problem.

/etc/ssh/sshd_config
ClientAliveInterval 1
ClientAliveCountMax 1

The ssh sessions on Mircwood (spooler and astropci) will keep running inside screen. To reattach them login again into mirkwood and type :
screen -r

Attach the two session in separate terminals.

The GUIs on lothlorien can be launched by typing gui_startup S1E1W1W2 (or the baseline configuration you are in).

In ~/mirc_python/scripts there are all the scripts for starting each separate gui. They do not start in a terminal on purpose but the output of any of them cam be attached through screen at any time, even remotely for debug purpose. Do screen -ls to see the list of screens running. do screen -r <screen number> to attach a specific screen.

Installed sshfs. Directories on mirkwood are available from the observe home directory on lothlorien.
~/mirkwood gives access to / as spooler
~/backup gives access to /backup as spooler
~/staging1 gives access to /staging1 as spooler
~/staging2 gives access to /staging2 as spooler
~/data gives access to /data as spooler

They are all symbolic links to ~/sshfs. Other can be made as necessary; ls -al of the symlink will give the syntax to access the automounter (afuse). 

The webdaq data is available in ~/webdaq.

I recommend of not using cp -rp to copy data better use rsync tha allows to maintain the time stamp without trying to change the owner of the file. I left an example with a sticky note on the desktop.
