Hi,

Does anyone know the password recovery procedure for

old Altiga VPN concentrator??

Modle number is C5 which is similar to Cisco's VPN 3005 Concentrator but running on old..old IOS.

Thank you

Here are the steps:

1. At the console type " p". This will bring you to the pROBE+ prompt.

2. Type "nv 1". This command will dump the NVRAM informatation, 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

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

4. 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".

5. Type "prb". This WILL cause a reboot.

After the concentrator reboots, the administrator password will be reset to the factory default.
