super.  these changes have been committed, so you can have the full file

Thanks.  I just tried, and got the same "end of run not found."  Then I 
realized I wasn’t merely cutting/pasting from one location to another, but also 
the specific logout text test changed; once I updated to what you showed, it 
worked perfectly.  Also - the lines I had were at different indexes, and 
different offsets between old/new locations where the commands moved.  For 
reference, diff below not to my .in file (I don’t have the original install 
makefiles), but against the production library file.

Lest I forget – Muchos mahalo for the help on this the past few months working 
through things.

I added those lines to 3.4.1.  I didn't dig too deeply into the 3.8 code, so if 
it's already fixed there then no worries.

3.8 has versions of these; it is not clear to me if you are saying that
you added these to 3.8, or if you needed them in addition to what is in
3.8.

Re: [rancid] Unable to Conduct Cisco Wireless Controller Backup

> this is a(nother) design flaw in the o/s, imiho.

FULLY AGREE!  "config pager disable" is a per-session setting, and has no 
permanence.  I tried setting it, and it lasted the duration of my session, but 
once I logged out/in the CLI reverted to a paging behavior.  And yet, it's not 
available to a read-only user.  G

I'll start working with the wlogin from 3.8, and either upgrade rancid 
(management depending), replace wlogin, copy wlogin to wlogin-3.8 and define a 
new WLC type in rancid.types.conf, or as a last resort copy/paste the 
appropriate change.

Thanks for the help through this process.

WLC CLI authorization mechanism is all bork bork bork.  I can set a read-only 
role, but that disables the ability to issue the "config pager disable" command 
since the entire "config *" command tree is not available.  I can set a higher 
role, and perhaps the command will appear, but I'm struggling to figure out how 
to create a custom role definition (I suspect it might be impossible since the 
Cisco WLC is designed to be GUI-based).   We can discuss another time allowing 
automation to make changes to the system - I'm fighting this battle internally 
but it's not going well, for now let's just say I need to demonstrate 
confidence that rancid will only get data, not change anything more complicated 
than a "last login" notice.

this is a(nother) design flaw in the o/s, imiho.  as in ios, the pager
should only affect the given vty, not the config of the device.  not needing
to manipulate the pager is very convenient.

> In any event - so, this leaves me with the CLI role I have, and without 
the "config paging disable" to be used.

you could also change the config to disabled the pager, if most folk just
use the web UI.  or try setting the stty rows to some large number before
initiating the connection to the device; it might honor it, but i've seen
many of these half-baked platforms ignore it if it doesn't lie within some
unspoken acceptable range.

> I'm running rancid 3.4.1, I notice the latest 3.8 is slightly different 
in wlogin.  But, they're relatively similar, and neither version (I think?) 
catches the specific prompts that might appear to prompt for paging.  Might 
they possibly be added?  See below what I did to wlogin v3.4.1 (aka my 
installation), let me know if I did this wrong (I'm an accomplished network 
engineer... but a poor excuse for a software engineer).
> 
> Also, wlogin uses "exit" to close the CLI when -c or -x is specified; it 
needs to be "logout" instead regardless of user role.  Where do I change this?  
I suppose I can do this in rancid.types.base (.conf?), but I'd prefer not to 
since I /do/ use *login with the -p and -u options on occasion with some simple 
BASH command-line scripts to accomplish manual campus-wide pre-planned changes. 
 I tried grep'ing through some files, that didn't work too well.

you just need a newer wlogin; current is using logout.

Re: [rancid] Unable to Conduct Cisco Wireless Controller Backup

I did some experimenting, issuing the "config paging disable" CLI command on 
initial login seems to eliminate the paging issue, similar to the ASA "terminal 
pager 0" or the IOS "terminal length 0".

i dont see the problem in what you've provided; you'll have to share more
output with me.

eval `rancid -t cisco-wlc8 -C hostname` &> output

I should note that using the NOPIPE=yes thing causes the "controller wlogin 
error: Error: Connection closed (ssh): controller" message that I show below.  
If I omit the NOPIPE environment variable on the CLI, I get the output I showed 
in the other email, where it hangs in the middle of output.

Hi Heasley,

I was finally able to try this out.  Actually - more specifically, I tried 
the same command on this WISM2 that I tried a moment ago on the WLC 8540, and 
got 100% identical results. I don’t think this issue is in catching the logout, 
though if you want me to I can try your patch below.

I just tried five times on three different controllers; I got 100% success.

[rancid] Unable to Conduct Cisco Wireless Controller Backup

[Piegorsch, Weylin William]

Hello,

I’m running rancid v3.4.1.  I have a number of Cisco WISM2 controller running 
8.2.166.0.  rancid is not able to acquire any of their configs.  I’ve tried 
various types in router.db: cisco-wlc4, cisco-wlc5, and cisco, none of them 
work. The logs, copied below, show the results of cisco-wlc5 (all controllers 
were identical, I’ve trimmed down to just one).  What could be causing this?  
Why would the results vary across the five rounds?  And, which type should I be 
using?
