You may also want to look at a tool called Solarwinds. It's great for
obtaining the encrypted password for router access. It also has a config
viewer for extracting the running config from a router. - Nice tool -

I couldn't see this in the thread, only a bunch of links to various pages,
and since I
am off-line at the moment (and probably WAAAY behind reading this...), I
leave it
to the moderator to approve the post.

One good way to do a packet dump on a Cisco is:

        router(config)#access-list 199 permit ip <source> <mask>
<destination> <mask>
        router(config)#access-list 199 permit ip <destination> <mask>
<source> <mask>
        router(config)#end
        router# debug ip packet 199 dump

E.g.

        access-list 199 permit ip host 192.168.0.1 any
        access-list 199 permit ip any host 192.168.0.1

Will dump packets destined to and from 192.168.0.1.

I included the list, since debugging at packet level can cause the router
to reload if there is a lot
of traffic.
