Failed Password Prompt Matching

[NthNEK]

Hi,

Just started using scrapli today and I've read for hours, nearly everything I can find and didn't find the answer so I apologize if this is documented somewhere... I have some devices that provide a specialized password prompt (from TACACS+) that scrapli was unable to detect (such as seen in the following relevant logs):

DEBUG:scrapli.channel:read: b'(<user redacted>@<host redacted>) Password <other words redacted>: '
CRITICAL:scrapli.channel:operation timed out, closing connection

Since I'm using the standard core transport SystemSSH, I found and modified line 114 in scrapli/channel/base_channel.py:

From:

self._auth_password_pattern = r"(.*@.*)?password:\s?$"

To:

self._auth_password_pattern = r"(.*@.*)?password.*:\s?$"

...just adding in the .* between password and : as a test. This fixed my issue for testing purposes, but I'm wondering if there's a better way to handle altering the password prompt that I'm missing? I'd prefer to use a method that won't be broken upon updating scrapli from pip/source.

there is a property w/ a setter on the channel, so I guess that would be the "recommended" way to change this. that is here

so something like my_conn.channel.auth_password_pattern = blah should do the trick

A much faster answer than I expected. Thanks for all your work on this, Carl! It is truly appreciated.

My tired eyes yesterday didn't even realize I was posting this question in the scrapli_community discussions section when I thought I was in nornir_scrapli.
