[c-nsp] 2511 as console server - connection refused?

[Garry]

Hi,

I just set up an old 2511 as console servers for several boxes we are
running at a colo housing. Everything works fine, I configures several
host aliases like "ip host fw 2007 XX.XX.XX.XX", and connecting via
"telnet fw" will work. Anyway, out of the (currently) 6 connected boxes,
I often get a "% Connection refused by remote host" from one or two. I
try it again some time later, and it will work, but others give the
connection refused message. Reboot the 2511, and those work, but another
won't. Am I missing something here?

Here's the config I have:

line 1 16
 session-timeout 20
 exec-timeout 0 0
 transport input all
 autohangup
 stopbits 1
 flowcontrol hardware

Any idea?

Tnx, -gg
