VPN3000 Concentrator (Altiga) password recovery

[rhugo]

Hey All,

I have a VPN3000 (altiga) with a software version 2.2 and can't figure out a password recovery procedure for this unit. I have looked in the Archives as well as scoured the Cisco site and numerous newsgroups. Any help would be appreciated before I have to break down and open a TAC on this guy.

Thanks,

Rob H.

Rob,

I did a search and came up with this document......

http://www.cisco.com/warp/public/474/pswdrec_vpn3000.html

It does state though.....

Note: For concentrators running code version 2.5 or earlier, contact the Cisco TAC for password recovery assistance.

Sorry for the bad news.....

For pre-2.5 concentrators, try this:

It requires that you corrupt the NVRAM checksum, thereby causing the NVRAM to be re-initialized. It also requires being physically connected to the console or via modem.

At the console type " p". This brings you to the pROBE+ prompt.

Type "nv 1". This command generates the NVRAM information, which looks something like this:

NVRAM Section Information

NAME SIZE ADDRESS XSUMMED

CHKSUM 00000418 c0000000 Y

PSOS 00000100 c0000418 Y

BOOT 00000200 c0000518 Y

SYSTEM 00000100 c0000718 Y

DIAG 00001000 c0000818 Y

CFG 00000200 c0001818 Y

EVENT 00040030 c0001a18 N

PROBE 00000800 c0041a48 Y

Determine the address of the CHKSUM section (in this case c0000000).

Type "pm address data" where address is the address of the CHKSUM section and data is any non-zero value. In this example, you would type "pm c0000000 5".

Type "prb". This causes the VPN Concentrator to reboot.

Rebooting the VPN Concentrator resets the administrator password to the factory default.
