I'd like to write a perl or shell script to run as a cron job on a machine at a remote location (an ssh server that I need to access from time to time) that can test to see if its network connection is working, and if not, try to re-establish it by restarting networking, rebooting or something else.

What can my script do to determine if it is connected to the router, and if the router is connected to the internet?

Also, is there any kind of inexpensive device that will enable the computer to reboot a dsl modem/router (i.e. just turn it off & on again)?

I had a similar issue about 18 months ago:

Can't help you with the router reboot, tho'...


cheers,

Thanks, that's a good idea. I can ping the router to verify the inside connection, then ping an external site to check the internet connection.

Now I just have to shop around for something to switch the router's power off/on.

mrclisdue,
Please don't put links in "Code:" blocks -- they can't be clicked. Also, you have "trashed" this thread w/ that "Code:" block so that many Konqueror users (& who knows who else) get a huge horizontal scroll, which makes this very difficult to read. As a result, some may not bother to read the OP; this will reduce the pool of helpers. I, for one, won't, until the horizontal scrolling is gone. Please, edit & fix this. Thanks.
