I have a net--telnet script that collects data from Cisco devices, and
it's pretty basic. I am adding ssh v1 &v2 support so I can collect data
from devices that force Cisco's SSH version on that device. So far, as
long as the device answers to ssh, it was a pretty easy task. But if the
system has no ssh ability, and I hit it with the script, it dies and
kills my script.
I have not done much error handling with scripts, so I was hoping I
could get some ideas on how to allow my script to recover from this
connection failure and let me drop to a telnet attempt.
I suppose I could do a test before calling the ssh module, see if
tcp/22 is answering, but net::telnet does a nice job of providing an
error of it cannot connect, does net::ssh::perl do that?
