A script to make sure that my IPv6 Tunnel is always on

I’m using an IPv6 tunnel using, and when the internet connection goes down and up after a while, the tunnel just doesn’t refresh it self.
I run it on crontab for every 5 minutes for now 🙂
My Machine is Gentoo 2008, I guess you need to do some changes for it to work on your distro.
Hope that any one will benefit from it

function restartGW {
	/etc/init.d/gw6c restart
	date >> /var/log/checkipv
stat="`/etc/init.d/gw6c status | tr -d ' ' | cut -d':' -f2`"
if [ $stat == 'stopped' ]
elif [ $stat == 'started' ]
	IPV4connected="`echo $(nc -zv 80 2>&1) | cut -d')' -f2 | tr -d ' '`"
	if [ $IPV4connected == "open" ]
		# check ipv6 connectivity
		IPV6connected="`echo $(nc -6zv 80 2>&1) | cut -d')' -f2 | tr -d ' '`"
		if [ $IPV6connected == "open" ]
			exit 0;
exit 0

Are you from the past?

The IT Crowd is one of my favorite shows, it became like an addiction to me, I can never get enough of it.
This is episode 1 from the first season, you can watch it, it’s on google-video.

UPDATE: Google Video no longer exists, so this is the part from Youtube.

Now, it seams that the “Are you from the past?” thing, is faced a lot in the IT world, it’s like either we are from another planet, or we live in a world, where idiots are main population occupying it.
We speak in simple matters, like turn on your computer, but people find it hard to understand.

People refuse to think for a second of what the error message told them, or worse, they refuse to read the error message, but they have an amazing skill of attracting viruses, worms and Trojans. It’s really amazing.

And do you know what the problem is? a lot of these people work in the IT industry, and other people might know them as Computer Experts.

Now the issue is always, how to communicate with them, of course telling them that they are stupid, is rude. But guess what is also rude, telling them to try to learn, or use google, or read the G** D*** F***** Message.
And believe me, they would never learn.

So what do you think? Anybody has any ideas?

Ftp using curl

This post just a reminder for me, as every time I need it, I look through the manual for options, to send a file through FTP using the command curl

$ curl ftp://server/Path/To/Destenation -T FileToUpload -u username:password

I just keep forgetting it, hope it would help someone else 🙂
