Hello I am trying to do automation using Python for SSH for a specific device.
I am running output like this to display in the console the commands that are listed.
stdin, stdout, stderr = pre_ssh_conn.exec_command(command1)
output1 = stdout.read().decode('ascii').strip("\n")
stdin, stdout, stderr = pre_ssh_conn.exec_command(command2)
output2 = stdout.read().decode('ascii').strip("\n")
stdin, stdout, stderr = pre_ssh_conn.exec_command(command3)
output3 = stdout.read().decode('ascii').strip("\n")
print("Command Output: ", output1)
print("\nCommand Output: ", output2)
print("\nCommand Output: ", output3)
print('\n\nINFO: Commands Executed Successfully')
All commands seem to give me an output except one specific command.
When running
asg stat vs all
on SSH I am getting a result, - [ SSH without my python script ] but when running it via my python automation script: I am getting an empty blank line. I was wondering if someone could give me insight as to why I would be getting a result via ssh, but not via my python script (all other commands such as uptime, etc seem to display an output in the python terminal, so I know the code should work.)
The only thing I can think of is via SSH the second command provides a blank line first, for example:
SSH Output
[User@BLAHBLAHBLAHBLAH:ACTIVE]# uptime
16:15:30 up 299 days, 21:24, 1 user, load average: 1.19, 1.22, 1.03
[User@BLAHBLAHBLAHBLAH:ACTIVE]# asg stat vs all
Chassis vs all is supported with Dual Chassis only.
[User@BLAHBLAHBLAHBLAH:ACTIVE]#
My code output in terminal:
Command Output: 16:05:45 up 299 days, 21:14, 2 users, load average: 0.88, 0.88, 0.83
Command Output:
Edit
Following bellow comment, even using using method gives me a strange output.
stdin, stdout, stderr = pre_ssh_conn.exec_command("bash --login -c " + "asg resource")
