[TriLUG] a perl/expect/IOS question

[Greg Brown]

Thanks for the ideas, Weave.  I tried both ways and got the same result I'm
afraid:

in subscript: output of sending new config: r2821(config)# tacacs-server
key 7 0115140B551F02002E5E
in subscript: output of sending new config: %Invalid encrypted key:
0115140B551F02002E5E

However, if you copy and paste it (just to prove to myself that I'm not
insane) it works:


r2821(config)#tacacs-server key 7 0115140B551F02002E5E
r2821(config)#

Oy.

Greg
