I'm trying to SSH into final_machine
via the jump host portal_machine
. Both remote machines are Linux, local is Windows. When I run the following command in a cmd, I can successfully connect
ssh {username}@{final_machine} -oProxyCommand="ssh -W {final_machine}:22 {username}@{portal_machine}"
And I can also successfully connect through python with
ssh_command = plumbum.local["ssh"][f"{username}@{final_machine}", "-o", f"ProxyCommand=ssh -W {final_machine}:22 {username}@{portal_machine}"]
ssh_command()
However, I need to connect via an SshMachine
object for compatibility, and when I try the following, it fails
plumbum.SshMachine(final_machine, user=username,
ssh_opts=[fr'-o ProxyCommand="ssh -W {final_machine}:22 {username}@{portal_machine}"'])
with error
Return code: | None
Command line: | 'true '
Host: | {final machine}
Stderr: | CreateProcessW failed error:2
I've tried replacing ssh
with C:\Windows\System32\OpenSSH\ssh.exe
, but no change. I have SSH keys set up from my machine to portal_machine, my machine to final_machine, and portal_machine to final_machine. Any other suggestions for how to debug would be appreciated. When I connect simply to the portal machine, it works fine.
I would rather use ProxyJump
than ProxyCommand
, and move as many settings as possible into ~/.ssh/config
.
Sample configuration for the mentioned hosts:
HOST portal
HostName portal.machine.host.name.or.IP
User username
IdentityFile ~/.ssh/your.portal.key
HOST final
HostName final.machine.host.name.or.IP
User username
IdentityFile ~/.ssh/your.final.key
ProxyJump portal
Tunnel then with:
machine = plumbum.SshMachine('final')
pwd = machine['pwd']
pwd() # '/home/ec2-user\n'
