The design: multiple network security zones, some with Linux servers only, some with Windows only.
Objective: Secure Copy (
scp) between two Linux servers using a Win10 OpenSSH as proxy
linux1 (zone A) > Win10-1 (zone B) > linux2 (zone C)
[Updated: some progress] Authentication is SSH key based. I ran ssh-keygen on
linux1and copied the .pub file to
Win10-1, then copied the content into
C:\Users\[username]\.ssh\authorized_keys and this works as intended: I can ssh from
linux1 into the
The same procedure should work when running
Win10-1; I have my key pair and copy the pub file to
linux2 but logging in from
ssh user@linux2 fails and the Powershell prompt hangs - but if I do
Start ssh user@linux2, then it works.
To test the intended connection, I did:
#linux1: ssh -J username@proxy-win10 username@target-linux2
And it gets me through just fine - but only after prompting for the login password on
I suspect that the final hurdle is that required
Start ssh user@linux2 - is the OpenSSH server instance maybe broken?
