[rancid] Extreme Networks - Disable CLI Paging

[Paul Thornton]

Hi

I have had this exact same issue; and we fixed it with the attached 
patch to clogin (not xrancid - the problem is a mis-identification of 
the prompt).

However, there is a patch on the mailing list here:
http://www.shrubbery.net/pipermail/rancid-discuss/2009-February/003645.html

which should also achieve the same thing (although I have not tried this).

Paul.

Assuming this is old stuff as now they can. Running XOS v15 on these X440’s. The command “disable cli paging” will disable the pager per-session.
