Router Password

[amitbh]

Hi,

I am managing 100 no. of routers. For securoty reasons, I have to change the passwords of all these routers once in every 15 days.Is there any command/tool/software to achieve this so that I can change the passwords of all the routers in one go.

Thanks in advance.

Hello,

check this link, it describes a procedure to change the enable passwords using SNMP and a tool from Solarwinds:

How to reset an enable secret password via SNMP

http://support.solarwinds.net/Help/Config-Uploader/Reset-Enable-Password.htm

The basic idea is to upload a configuration with the new password to the router. You can also use a simple script to achieve this:

To reset the password using SNMP.

First read the config to your tftp server...

/usr/OV/snmpset -c

.1.3.6.1.4.1.9.2.1.55.ipaddress.of.tftpserver octetstring

server>

Next edit the config substituting the new, plain text, enable secret password

Enable secret

then tell the router to boot the config on your tftp server (tftp server needs to be on the same subnet)...

/usr/OV/bin/ snmpset -c

.1.3.6.1.4.1.9.2.1.50.ip.address.of.tftpserver octetstring

server>

And the new config is running, telnet to the router and try your new password... then copy the running config to startup...

HTH,
