router-snarf - retrieve router configuration files

router-snarf [-user=user] [-userpw=pw] [-enablepw=pw] [-noclobber] [-dir=outputdir] router...

router-snarf [ -user=username ] [ -userpw=userpw ] [ -enablepw=enablepw ] [ -noclobber ] [ -dir=outputdir ] addr [addr ...]

router-snarf logs in to one or more network devices and retrieves the configurations.

user

The CW-user flag specifies the username to use when logging in. The default is the current username. If this is not specified, the contents of the environment variable SNARFUSER are used, if defined.

userpw

The CW-userpw flag specifies the user password to use when logging in. If this is not specified, the contents of the environment variable USERPW are used. If USERPW is not defined, the user is prompted for the password with echo turned off.

enablepw

The CW-enablepw flag specifies the enable password to use when enabling. If this is not specified, the contents of the environment variable ENABLEPW are used. If ENABLEPW is not defined, the user is prompted for the password with echo turned off.

noclobber

The CW-noclobber flag specifies that existing configurations are not to be overwritten.

dir

The CW-dir flag allows the specification of an alternate directory in which to store the configs that are retrieved. The default is the current directory.

-V, --version

The CW--version option displays the current program version.

The addr argument(s) allow the user to specify the names or addresses of the configurations that are to be retrieved.

0 - success >0 - some error occurred

 $config                        - the config file that was pulled

This program uses Telnet to retrieve configurations. Telnet sends passwords and configs (which contain router passwords) in the clear over the network. These passwords and configs can be intercepted by other users (or intruders) on the local network. If you use this, be sure you only traverse networks that you own and that you trust every user and system on those networks. A better solution would be to use an encrypted solution such as SSH or IPSEC.
