So the other day I was looking around and discovered the notify-send<\/a> command. It basically sends notifications to the desktop. Pretty useful now adays.<\/p>\n

[11:49:13] xavi@thinkpad: ~ $ sudo dpkg -S `which notify-send`
\nlibnotify-bin: \/usr\/bin\/notify-send
\n[11:49:15] xavi@thinkpad: ~ $<\/b> <\/p>\n

It is installed with libnotify-bin via aptitude.<\/p>\n

[11:50:35] xavi@thinkpad: ~ $ sudo aptitude install libnotify-bin<\/b><\/p>\n

So, once installed lets create a practical script. On my job I need to have a permanente VPN<\/a> connection. Once in a while the VPN connection drops and we have to connect again. Lets create a simple script that notifies us when the connection drops.<\/p>\n

[bash]
\n#!\/bin\/bash<\/p>\n

# Check tunnel interface
\nwhile "true"; do
\n \/sbin\/ifconfig tun0 &> \/dev\/null
\n while [ $? -ne 0 ]; do
\n notify-send -t 5000 "VPN" "VPN is down"
\n done
\n sleep 300
\ndone
\n[\/bash]<\/p>\n

We save and copy the script, give it execution permissions with chmod and send it to background.<\/p>\n

[11:55:47] xavi@thinkpad: ~ $ chmod +x \/tmp\/check-vpn.sh; \/tmp\/check-vpn.sh &
\n[1] 15613
\n[12:00:43] xavi@thinkpad: ~ $<\/b> <\/p>\n

Here is a screenshot of it working.<\/p>\n
