I was using the TIS Toolkit's portscan the other day, within my employer's
domain, just to verify general tightness, when it occured to me to run it
against an interface on my cisco 4000. I made sure that I ran it from an
IP address that the cisco will ignore TELNET SYNs from. IP, RIP, Vines
and IEEE bridging are enabled on the router, but only RIP and IP are active
on the particular interface, with RIP neighbors defined. The IP subnet
I ran the test from, however, is generally "trusted" by the router.
I expected the first three results, but the last five have made me curious.
I'm hunting it down now, but thought it an interesting enough result to bring
to general attention in the meantime. The only other routers that I can test
against are Wellfleets and a Morning Star Express; haven't done it yet, though.
I can apparently make a TCP connection on those numbered ports.
Things that make you go "hmmmm"... although it's probably something trivial
-- which I'll discover only minutes after sending this message out ;).
