FIOS Router CLI and DHCP
I recently got Verizon FIOS service. The router Verizon provides is an Actiontec MI424WR. Verizon goes to some trouble to hide the Actiontec branding; but, for example, the Model Name field in the System Monitoring tab on mine says "MI424WR-GEN2".
Anyway, I wanted to get the DHCP lease database out of the router in order to populate that information into my own DNS server. I initially looked at scraping the web interface, but the router does some weird Javascript hashing of the password before submitting it to the server. I figured there had to be a better way.
In the advanced options you can turn on telnet access to the router. That gets you into a command line administration utility, which in turn will let you access a shell (via "system shell"). However I was unable to find a DHCP lease database in the filesystem. There was a /var/state/dhcp directory, but it was empty.
Some searching on the web turned up the fact that the Actiontec MI424WR runs a commercial Linux distro called OpenRG. More searching turned up an OpenRG Configuration Entries Guide. A bit more poking and I found that this command will dump out the DHCP lease database:
conf print dev/br0/dhcps/lease

Any chance of updating this with a link to the OpenRG configuration entries guide?
For people who end up here via Google...here's a config guide: http://www.scribd.com/doc/88752930/Openrg-Configuration-Guide
Thanks for adding a URL. At the time I wrote this the only copy of that guide I could find online looked to be at a URL that wasn't likely to stay around long so I did not link to it.
