Does any one know of a proper way to secure telnet sessions to routers.

Re: Secureing telnet

theres lots.

Some considerations:

1. how many routers? If its a large network look at a

centralized aaa system (cisco secure)

2. you can build a local authentication database on

each router and have users authenticate that way

heres an bit on dynamic access lists.

Otherways:

Access-lists with AAA/local Auth (however, hashs/passwords are open to public ie., not encrypted).

Better to use:

SSH

Kerberos
