ssh debug log for the node as seen in vim:

^(^M)?([\w(:.@-]+()\s?[^\*]]?[?\w*]?\s?)*?[#>]\s?)$
regex updated to match aos8 for wireless controller and mobility master but seems to fail only after using cli no paging

Hello,

I can confirm this.
Just like you I first modified the prompt regex to match AOS 8. But when I got the prompt to match it stops after no paging.
Pretty sure I got it to continue to the next command if I added a \n to the no paging command in the aosw.rb file if that would help in troubleshooting. However after the next command, it stops again.
Debug log for my node:

^M
(X-VPNC-7005-02) *#no paging
^M(X-VPNC-7005-02) *#

here is a workaround for the issue. **post_login "no paging\nshow version"**
change aosw.rb model file (oxidized/lib/oxidized/model/aosw.rb) to

cfg :ssh do
    if vars :enable
      post_login do
        send "enable\n"
        cmd vars(:enable)
      end
    end
    post_login "no paging\nshow version"
    pre_logout 'exit' if vars :enable
    pre_logout 'exit'

@yoakim, did try adding \n after no paging such as "no paging\n" or ''no paging\n\n\n" but still didn't help.

[yoakim]

Thanks for the workaround! Any idea why that works?

^M is typically the representation of carriage-return, and can be matched by including ^\r? at the beginning of the prompt regexp, rather than ^(^M)?

I m having exactly the same issue with oxidized stopping right after "no paging". Has anyone been able to fix this ?

Hi!
I had the same problem and i've solved as follows:

Backup your "aosw.rb" file;
Edit your "aosw.rb" file:
1- If you Aruba prompt show:

*#
So, edit the prompt regex:
From: prompt /^([\w\(:.@-]+(\)?\s?)[#>]\s?)$/
To: prompt /^(\^M)?([\w\(:.@-]+(\)\s?[\^\*]?\[?\w*\]?\s?)\*?[#>]\s?)$/

If this is not your problem, just pass to step 2.

2- Edit "post_login" statements:
From: post_login 'no paging'
To: post_login "no paging\nencryp disable\nshow running"
And comment all others "post_login" lines:

I hope it helps.

Hello,

I've just finished troubleshooting of this because no workaround from this thread worked for me. I've changed prompt regex in "aosw.rb" file to: prompt /.*([\^\w\(:.@-]+(\)?\s\*?(\[.*\])?\s?)[#>]\s?)$/
It looks like Oxidized couldn't recognize beginning of the line character, which was showing as ^M (Control-M).

[lucdnb]

This your workaround is just one part of the possible solution.
Paste your debug if you want, and we maybe solve it.

Hi, another example of a prompt not matching...
(hostname) [mynode] # not matching configured prompt (?-mix:^([\w\(:.@-]+(\)?\s?)[#>]\s?)$)"

I've modified my aosw.rb and restarted oxidized...do I have to do anything else to pick up the prompt change?

Hello,
Try to change that regex in aosw.rb file to the one which I've posted above:
prompt /.*([\^\w\(:.@-]+(\)?\s\*?(\[.*\])?\s?)[#>]\s?)$/

[techjockeynet]

Thanks jesusko, this is working..the issue was not your prompt it was my aosw.rb location...aparently it wasn't the one in /opt/oxidized/model/...it was located in /usr/local/lib/ruby/gems/2.4.0/gems/oxidized-0.28.0/lib/oxidized/model/
Thanks again! You rock!
