SilverFile Server Administration Guide and Tips
Add users to sudo
Sudo allows all users in admin group root privilege. This is something that Ubuntu sets up as an alternative to visudo.
usermod -a -G admin ryan
SSH Keys
To generate a key:
ssh-keygen (or) ssh-keygen -t dsa (for dsa) (do not enter a passphrase)
This generates, id_dsa and id_dsa.pub. Client(id_dsa) ---ssh--> Host(id_dsa.pub in .ssh/authorized_keys)
Disk Usage Tools
Get a summary of disk usage for each client folder. Sort the output alphabetically.
du -h --max-depth=1 | sort -k 2
Using Screen
Screen is an excellent utility for managing shell sessions remotely.
screen
Within the new shell, enter Ctr-A d. This disengages you from that shell but still allows it to keep running.
screen -ls (lists screen sessions) screen -r xxxx.tty.session (allows you to re-attach to a given session)
SSH Tunneling
If you want to tunnel the tomcat instance (running nutch) try this command:
ssh user@harvey.silverfilecorp.com -p 2222 -L 8080:localhost:8080
Init Scripts
Add an init script Add the script to /etc/init.d/ and then run:
update-rc.d script_name defaults
Remove an init script Delete the script from /etc/init.d/ and then run:
update-rc.d script_name remove
