You're both right. 2065 can be used for DLSw+, but it's also available
for aux reverse telnet - from the fact the original poster said that
4065 etc are open I would guess that they're open because of this, not
DLSw+.

I don't know how IOS handles the fact 2065 can be used for both DLSw+
and AUX reverse telnet. I would guess DLSw+ takes priority. (Unless
it's a case of "whichever process boots first and binds to the port")

I'm not losing my mind, no I'm not changing my lines,
I'm just learning new things with the passage of time
