[rancid] Device not contacted

[Ryan Milton]

Thanks Alan,

I don¹t think I even get that far! I get a hangup almost immediately.

BUT! I noticed that there should have been no issue given that those
commands worked perfectly. The problem was that the Netscreen was set to
³| more² rather than blurt out the whole config! That was a minor change
to the console output command to not limit to 20 lines at a time.

So, then I tested with rancid-run, it all worked!

Thanks for the time/tips, that was helpful to find the root cause.

Regards,
Ryan Milton
