Hi guys,
I can’t get command output from comamand show tech-support from cisco devices. The below code works while collecting logs for small outputs like ‘show version’ etc. But the script hangs when trying to run tech-support. I understand it is related to read_time, but I can’t find solution(i’m python beginner 
).
import getpass
import re
import datetime
from pathlib import Path
from scrapli import Scrapli
username = 'cisco'
password = getpass.getpass("Enter password: ")
enable_password = getpass.getpass("Enter enable password: ")
with open('device_ip.txt') as routers:
for IP in routers:
IP = IP.strip()
Router = {
"host": IP,
"auth_username": username,
"auth_password": password,
"auth_secondary": enable_password,
"auth_strict_key": False,
"transport": "paramiko",
"platform": "cisco_iosxe",
"transport_options": {
"paramiko": {
"kex_algorithms": [
"diffie-hellman-group-exchange-sha256",
"diffie-hellman-group14-sha256",
"diffie-hellman-group-exchange-sha1",
"diffie-hellman-group14-sha1",
],
},
},
}
print(repr(IP))
connection = Scrapli(**Router)
connection.open()
print ('Connecting to ' + IP)
print('-'*79)
output = connection.send_commands_from_file("command_list.txt")
#output = connection.send_configs_from_file("config_changes.txt")
print(output.result)
# Extract the hostname from the tech configuration
hostname = re.search(r"hostname (.+)", output.result)
if hostname:
hostname = hostname.group(1)
else:
hostname = "unknown_hostname"
# Create the backup directory if it doesn't exist
backup_dir = Path(".")
backup_dir.mkdir(parents=True, exist_ok=True)
# Save the output to a file with the date and hostname
# Save the output to a file with the date and hostname
current_date = datetime.datetime.now().strftime("%Y-%m-%d")
file_name = f"{current_date}_{hostname}.txt"
file_path = backup_dir / file_name
with file_path.open("w") as f:
f.write(output.result)
print(f"Saved config to: {file_path}")
connection.close()
Enter password:
Enter enable password:
‘10.10.104.1’

I tryed to change how you said, but then does’t work at all. I attached errors, maybe now it will be more clear. Like I said script works fine, but problem is with only one cisco command(show tech-support). To get answer from this command script need to wait, but he doesn’t want to do it.
