Seriously, $100 for *barcode labels*?

Instead, pick up some sheets of 8"x11" Avery label stock, and print your own.

Automated reboot of Netgear FVG318

I'm having trouble with some Netgear FVG318 wireless VPN routers. They can't seem to release their DHCP leases without a reboot, and there's no way to schedule a reboot on them.

Other than that, these are really great, reasonably priced little devices.

Hopefully my contacts with Netgear Support will yield a fix so that they don't run out of DHCP leases *for no reason*, but until then I need a workaround.

So, I used some wget magic to script logging in, saving the necessary cookies, and executing the reboot function.

Just replace your.fvg318.ip with your FVG318's IP, replace youradminpassword with your admin password. I doubt the line breaks will come out proper in blogspot, so I'll tell you that there is only one line of command between each comment line -- if it line wraps on here, you will need to make sure your copy that you run does not wrap those lines.

Then just set this up in a cron job to run every night at midnight and voila! No more unhappy uesrs, no more manual reboots.

In setting up MRTG to work with the NTI Enviromux Mini, I could not for the life of me get it to properly see the vendor's MIB.

So, if you're in the same boat, just change appropriate lines in the mrtg.cfg for your enviromux on the Humidity and Temperature lines to match these, to use the numeric OID instead of the name:
