(Comware) "Current terminal monitor is off" Flapping issue

[berilslv]

Hi Oxidized enthusiasts,

Im facing problem with git version flapping. Exactly the same problem as #1447 .
Problem screenshot: Here

I tried to solve issue by adding vars_map:

#IGNORE_DISPLAY_MY
if vars :ignore_display
cfg.gsub! /"! Info: Current terminal monitor is off. .*/, ''
Oxidized.logger.debug "Ignoring terminal off"
end

But without success.
I hope for some advices.

Have a nice friday guys! ;)

Can somebody help me with this issue? Im still getting this current info flapping.

I ran into the same problem with current master comware model and HP 1910/1920 switches.
First issue with the same problem seems to be #1447
These 19x0 units are tricky and cause very funky stuff with using 'send'
Here a snippet of writeshark telnet tcp stream with current master comware.rb and it explains how 'send' commands get input/output/prompts totally messed up:

After struggling with this I achieved not the prettiest but working model, which successfully works with the following units on telnet and ssh input:

• HPE 1910-24 Switch
• HPE 1920-8G Switch
• HPE 5820X-24XG-SFP+ Switch with 2 Processors
• MSR954 JH299A
• Switch 4200G 24-Port Software Version 3Com OS V3.02.04s56
• Switch 4210G 24-Port Software Version 5.20 Release 2202P18
  I don't have 1950 unit, but I expect it to work too...

Here's my current comware.rb. Instead of 'send' I use 'cmd' with additional prompt regex.

class Comware < Oxidized::Model
  # HP (A-series)/H3C/3Com Comware

  # sometimes the prompt might have a leading nul or trailing ASCII Bell (^G)
  prompt /^\0*(<[\w.-]+>).*$/
  comment '# '

  # example how to handle pager
  # expect /^\s*---- More ----$/ do |data, re|
  #  send ' '
  #  data.sub re, ''
  # end

  cmd :all do |cfg|
    # cfg.gsub! /^.*\e\[42D/, ''        # example how to handle pager
    # skip rogue ^M
    cfg = cfg.delete "\r"
    cfg.cut_both
  end

  cmd :secret do |cfg|
    cfg.gsub! /^( snmp-agent community).*/, '\\1 <configuration removed>'
    cfg.gsub! /^( password hash).*/, '\\1 <configuration removed>'
    cfg.gsub! /^( password cipher).*/, '\\1 <configuration removed>'
    cfg
  end

  cfg :telnet do

    password /^Password:/
  end

  cfg :telnet, :ssh do
    # enable command-line mode on SMB comware switches (HP V1910, V1920)
    # autodetection is hard, because the 'summary' command is paged, and
    # the pager cannot be disabled before _cmdline-mode on.
    if vars :comware_cmdline
      post_login do
        # HP V1910, V1920
        cmd '_cmdline-mode on', /(#{@node.prompt}|Continue)/
        cmd 'y', /(#{@node.prompt}|input password)/
        cmd vars(:comware_cmdline)

        # HP V1950
        cmd 'xtd-cli-mode on', /(#{@node.prompt}|Continue)/
        cmd 'y', /(#{@node.prompt}|input password)/
        cmd vars(:comware_cmdline)
      end
    end

    post_login do
      cmd 'screen-length disable'
      cmd 'undo terminal monitor'
    end
    pre_logout 'quit'
  end

  cmd 'display version' do |cfg|
    cfg = cfg.each_line.reject { |l| l.match /uptime/i }.join

Thanks mate for your great answer! I hope this will help for somebody, as i have migrated to different IT structure! ;)
