@doomedraven found this link https://www.mail-archive.com/paramiko@lag.net/msg00415.html that has assisted me with remediating the issue of paramiko.ssh_exception.ChannelException: ChannelException(4, 'Resource shortage')
Issue now is the terminal just hangs and no output is displayed. Here's an excerpt of the code:
stdin, stdout, stderr = targetConn.exec_command("sh nameif")
# print the output
for line in stdout.read().split(b'\n'):
print(str(line))
idk why you tag me all the time, im not paramiko expert
@doomedraven no issues, I'll not tag you any further.
@tintoy any assistance will be greatly appreciated.
Sorry, I have no idea, either; I haven’t used Paramiko in years.
@tintoy thank you
I have the same problem with a Nokia OLT and ZTE LTE I do not know what happened this is my logging

When I tried to run multiple commands, the ssh session close at the second command:
I only add this code:
command_list = ["show ver", "show run"]
for command in command_list:
stdin, stdout, stderr = target.exec_command(command)
for line in stdout.read().split(b'\n'):
print(str(line))
I got the error:
raise SSHException("SSH session not active")
paramiko.ssh_exception.SSHException: SSH session not active
Any ideas guys?
I am trying jumpssh library:
https://pypi.org/project/jumpssh/
Thank you for your response : )
Hey man, just wanted to say thanks for this piece of Code! truly helped me.
@doomedraven, I'm sorry. I posted the wrong error. Below was the intended:

Thank you for a prompt response.
