Password Recovery Confirmation

It seems we have a problem.

Our central IT Department is changing their external facing IP's due to a new ISP on the weekend.

The problem this creates for me: -

I have 2 sites that connect over a Site-to-Site VPN.

One of the routers I can get into over Telnet, because it uses a standard password (setup by our old Central company before we got taken over two years ago (I've only been here 6 months so do not have any communications with previous IT People

The other router uses a password which I do not know.

I know the standard password recovery routine - Break, confreg 02142, reset, read config, break level 7 password.

In order to do this though, you need to be at the Router... which is not possible as it is over 300 miles away.

Am I going on a road trip this weekend then ?

    Well you could always get the config and try to crack the password. If it just has the "password" command with service-password encryption those are easy to break with many websites. If it has an enable secret you could try cracking it with rainbow tables. There was a project not too long ago that was like seti that was setup to make a huge database of passwords and their equivalent MD5 hash. Cisco routers do not use a salt if I remember correctly making it feasible.

    Or have someone on site do it...

    If I had the config, then surely I'd have the password too :)

    I mentioned that I knew about level 7's being crackable

    My last option, I suppose, is to get another Router, and build a new config (I can do this knowing what I know about the remote site)

    Get somone to hook a laptop up to it and use RDP or some other method of remotly controlling their laptop.

    Sounds like a great idea! Otherwise what is the weather like these days for a road trip in Wales?
    I usually hang out on 224.0.0.10 (FF02::A) and 224.0.0.5 (FF02::5) when I'm in a non-proprietary mood.

    Also a good idea.

    However, there are no laptops on site, and no PC's nearby that we can hook up.

    Actually I've gone the other way...

    I found out this morning that the central IT dept were responsible for migrating the routers to their network in the first place - so surely one of them will know how it was done ;)

    Ah well, they're sending me another router.

    Luckily I have a configuration lifted out of another router that is connected in a very similar way, so I should be able to get that done and send it up...
