It's been my experience that the routers are all listening on that port 
by default, and we notice it as a result of people nmap'ing us:

Dec 15 17:27:16 MST: %RCMD-4-RSHPORTATTEMPT: Attempted to connect to 
RSHELL from a.b.c.d

Everything I've read indicates that additional specific configuration is 
required to actually enable this service. Still, it's always been one of 
my least favorite things about IOS. If I don't need it, it shouldn't be 
on. And why doesn't "show ip sockets" list it at all?

If I was a tinfoil hat person, I'd assume that is the NSA's back door.
