Add A10 SSHDetect : Pattern not detected: 'A10DEVICE\\-Active\\-affinity\\-def\\-vMaster\\[1/1\\]' in output. #3431

Open romio28 opened 6 months ago

romio28 commented 6 months ago

Hello, I'm trying to add the ssh auto detect for A10 device:

"a10": {
    "cmd": "show version",
    "search_patterns": [r"Advanced Core OS \(ACOS\)"],
    "priority": 99,
    "dispatch": "_autodetect_std",
}

Command output:

Current time is May-6-2024, 14:26 The system has been up 39 days, 14 hours, 35 minutes A10DEVICE-Active-affinity-def-vMaster[1/1]>

But i recive this error:

192.168.25.15 An exception occurred:

Pattern not detected: 'A10DEVICE\-Active\-affinity\-def\-vMaster\[1/1\]' in output.

Things you might try to fix this:

  1. Adjust the regex pattern to better identify the terminating string. Note, in many situations the pattern is automatically based on the network device's prompt.
  2. Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information.

Any help please?

@romio28 Can you turn on Netmiko logging and see what it shows?

@romio28 Can you show your entire code and your entire exception stack trace (i.e. all the lines of the exception stack trace).

romio28 commented 6 months ago

debug file: test.log

Code:

`from netmiko import SSHDetect, ConnectHandler import logging logging.basicConfig(filename='test.log', level=logging.DEBUG) logger = logging.getLogger("netmiko")

device = { "device_type": "autodetect", "host": "192.168.100.87", "username": "admin", "password": "admin123", }

guesser = SSHDetect(**device) best_match = guesser.autodetect() print(best_match) # Name of the best device_type to use further print(guesser.potential_matches) # Dictionary of the whole matching result device["device_type"] = best_match

with ConnectHandler(**device) as connection: print(connection.find_prompt())`

The problem is in the find_prmpt() function, it trying to go in enable mode, it work if I add the secret password:

The A10 driver requires enable password (as A10 requires enable mode to disable output paging and Netmiko requires this).
