Describe the bug

I want to login to my windows computer through SSH. Here is how I setup my Windows SSH server: https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=powershell

It works totally fine on my default terminal.app, but Warp not working.

To Reproduce

1. Setup a Windows SSH Server;

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Thank you, @Molin-L, for your input!

We will keep you updated on any developments regarding this issue through this thread.

Also, as @osmboy mentioned, you can workaround this issue by installing installing Cygwin on the Windows machine you'd like to connect to.

If the above workaround isn't helping, you can disable the SSH wrapper by navigating to Settings > Features. This will allow SSH to function normally, although it may disable Blocks functionality.

In the meantime, if you're experiencing the same issue, please consider adding a 👍 to the original post at the top or commenting with your details. Your contribution will help us understand the extent of the issue. Additionally, if you would like to receive notifications about any updates related to this issue, please click on the subscribe button.

Thank you for your understanding and patience as we work towards resolving this issue.

Same here. It says:

$ ssh user@host
'export' is not recognized as an internal or external command,
operable program or batch file.
Connection to host closed.

workaround： you can install cygwin on windows then ssh

This fix is not working for me. I have Cgywin installed and from the Terminal app, I can SSH and invoke bash with no issue. However, when I try to connect from Warp, The following error flashes for a split second before the connection drops:

~
Missing '(' after 'if' in if statement.

This error is probably thrown by powershell. You may have to disable windows own openssh server and then configure and start ssh daemon on cygwin

Hey @gordon8214 -- the issue is most likely that Warp's ssh wrapper is being invoked and attempting to 'Warpify' the SSH session -- which won't work because Warp doesn't currently support Powershell.

You can circumvent Warp's ssh wrapper by prefixing command to your ssh command, e.g.

command ssh user@host

Or you can disable Warp's SSH wrapper altogether in the 'Features' settings page:

Just leaving a comment to let you know it is not only on Windows Server. This happen on Windows 11 as well.

I'm here to report that I too am having this problem. Attempting to ssh from a Macbook to Windows 11. Here's the permalink to the command execution/output: https://app.warp.dev/block/kmiRSX8mEllNVdFZ0u3AIw

Alternatively, you can also switch to using another shell without the warp wrapper and then connect:

$ zsh
$ ssh user@windows.host

After switching to zsh (or whatever shell you prefer) Warp asks in the UI whether you want to wrap that shell, just ignore it.

Is there any date when this is going to be resolved?

Hi, any update on this?

+1 mac to windows ssh

Same here. It says:

$ ssh user@host
'export' is not recognized as an internal or external command,
operable program or batch file.
Connection to host closed.

same output. ssh with macOS native terminal works fine.

it seems like warp will export some environment parameters to ssh server but windows powershell does not support this kind of shell command?

Since we're tracking all SSH on Windows issues here, let me post the output that I am getting when trying to SSH into a Windows 11 host from Mac OS. I believe users in #1729 and #2027 were experiencing the same behavior or something similar.

As JKuhn mentioned, using a non-warpified ZSH works just fine.
