Re: Suggestions for remotely rebooting a DSL modem

Now I need a suggestion to stop my side from hurting after reading Gumby's reply. After consideration of the "trained animal through small hole" option, I decided there was too much of a security risk having to open a port because of the possibly of a malicious small trained animal gaining access through the open hole by either using a brute force entry or spoofing my trained animal. My friends can't be trusted to enter the office unsupervised as it might expose me to a sexual harassment suit on Monday morning from the inappropriate photocopied images that would be placed over everyone's monitor.

After a quick Yahoo search (I am boycotting Google), I ran across this product http://www.cpscom.com/gprod/bandaid.htm . It seems to take a simple automated approach to the problem. Furthermore, I don't see why a similar feature couldn't be added to the modem firmware. A simple "soft reboot on no ping response" feature.

I think I saw a device somewhere similar to the phone line solution you suggested.


There may be more to it than a ping. My ISP upgraded me to 2M download
speed, after which my modem would drop sometimes between midnight and
about 7 AM and not relock. A reboot fixed it. For a while I ran a timer
which disconnected power to the modem at 7 AM for ten minutes. I find
that brute force and ignorance is usually the best answer, and the modem
would never be in use at that time.

In case the problem spread to less predictable times, I tried a higher tech solution, with a failure of a reply to a ping to my (external) web
site triggering a script which logged into the router and rebooted it.
However, sometimes the ping continued to work while anything more
complicated failed, so I moved to downloading the home page using HTTP
three times in a row and testing for more than one failure. There would
sometimes be one missed download even when things were working.

It also depends what else you use the router for, if anything. An ISP
failure would cause frequent rebooting/power cycling, and some routers
are used as small hubs or switches. Work which could continue while the
ISP was out would be disrupted.
