If I understood the poster correctly, he wanted the hits on the router ACLs and such. This information will not leave across a reboot.
I would suggest checking if the attacker has changed the SNMP communities. If these along with the SNMP views are configured to allow you access to the interesting parts of the MIB you can get around the fact that you do not have an enable password.
If not - all you can do is get your router back as described by vb (does not work on all cisco models especially the more dinozauric ones, check with cisco web site for instructions on your exact model).

Otherwise, save bandwidth and lose the disclaimer. thanks for all the replies. and i am aware of the 3 given possibilities. but i thought maybe someone on the list has some quick answer as well?!? and as it is a little urgent i just wanted to give it a try! Unfortunately I do not know the new password! otherwise there wouldn't be a problem at all. and more unfortunately it is not my network and had nothing to do with the setup. or else i would have, as Mort pointed out, a tftp in place. -- Best regards, nonleft mailto:nonleft () gmx net _______________________________________________ Full-Disclosure - We believe in it.
