I am trying to create ssh reverse tunnel. When I run the below command on terminal it works greate:
autossh -M 10876 -N -f -o PubkeyAuthentication=yes -o PasswordAuthentication=no -i /root/.ssh/id_rsa -R 6666:localhost:22 root@**.**.**.** -p 2233
But when I run it in python with os.system()
or using subprocess
it's not working. When I check the processes list the process is created and running and has no difference with the last method.(running directly in terminal)
python code:
command ='autossh -M 10876 -N -f -o PubkeyAuthentication=yes -o PasswordAuthentication=no -i /root/.ssh/id_rsa -R 6666:localhost:22 root@**.**.**.** -p 2233'
proc = subprocess.Popen(shlex.split(command), stdout=subprocess.PIPE, shell=True)
Any idea What's the problem?
when you are using shell=True
, you don't want to use shlex.split()
on the command arguments... it should just be a string.
Since you are passing args to Popen
as a sequence, the first arg (autossh
) is used as the command, and the rest of the args are actually passed to the shell, not to autossh
.
So... you can either remove shell=True
, or pass args as a string by removing use of shlex.split()
.
