Thanks for your help.

I got the same error with Huawei VRP FWs. You have to ensure that the first line, after the ssh connection, will perfectly match the regex. I changed the regex in order to adapt it to the FWs. I know that it's a bit unorthodox but if someone here has other advices, please help :)

Thanks for your answer Giuseppe.

I have tried to adapt the prompt.

But I guess, I must get rid of the following lines : Your previous successful login (as operator) was on 2018-10-16 18:03:05 from 10.13.8.123

Did you managed that ?

Best regards,

@adebruyn-abit : Try to set no banner last-login on your HP device.

Also, banner motd " " and banner exec " " could be helpful. When setting this, these expect a delimiter (e. g. "a") and then type space, "a" and enter:

sw(config)# banner motd a
Enter TEXT message.  End with the character 'a'
 a
sw(config)#

This is so far the only way to set an "empty" motd and/or exec banner.

Just want to add this for anyone finding this thread 2020. My switches had both banner motd and banner last-login enabled, but thankfully only last-login caused an issue (my company would not allow me to remove their custom motd). However, I didn't feel like SSH:ing to 30+ switches so I copied the regex that I found on 'procurve.rb' and modified it so it now works with (and without) banner last-login.

The Regex:

/(^\r|\e[24;[0-9][hH])?([\w\s():-]+[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})?([\w\s.-]+[#>] )($|(\e[24;[0-9][0-9]?[hH]){3})/

Hello, Thank you for your help but I think there's a little issue with your regex (you forgot 2 "\") :

The Regex:

/(^\r|\e[24;[0-9][hH])?([\w\s():-]+[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3})?([\w\s.-]+[#>] )($|(\e[24;[0-9][0-9]?[hH]){3})/

I changed it to : /(^\r|\e[24;[0-9][hH])?([\w\s():-]+[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3})?([\w\s.-]+[#>] )($|(\e[24;[0-9][0-9]?[hH]){3})/ It works perfectly for me now :)

@DarkCatapulter Where did you update the regex for your Procurve switches? Was it in the Oxidized config YAML file or the procurve.rb file or somewhere else? Thanks!

@kingtriumph Hello, it's been a while since I commented on this thread. If I remember correctly, then it was on the procurve.rb file - Line 6. Give me a moment and I will double check it for you :)

[Faddy96]

@kingtriumph Hi again, I looked at my procurve.rb file to verify my previous comment.

Find the following line on procurve.rb file: https://github.com/ytti/oxidized/blob/8179f48545d94a1c6b3a096153f70e9eabff1e20/lib/oxidized/model/procurve.rb#L6

And change it to this:

prompt /(^\r|\e[24;[0-9][hH])?([\w\s():-]+[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})?([\w\s.-]+[#>] )($|(\e[24;[0-9][0-9]?[hH]){3})/

Hope this helps!
