Visual Studio Code Remote-SSH

[Snyder, Alexander J]

I use Visual Studio Code a ton. Whenever I've had an issue with SSH on code
it's usually due to an issue in the SSHD Config.

Check the "output" tab in VSC, as it'll have helpful output there.
Typically, in the SSHD Config file you'll need:

AllowAgentForwarding yes
AllowTcpForwarding yes
TCPKeepAlive yes

I would also *HIGHLY* suggest using key-authentication, just in general --
but most especially when using VSC with Remote SSH.

Thanks,
Alexander
