Have you tried commenting out my system & user rc files?

Screenshots

I set ControlMaster in my local SSH config file as follows:

When I run the command ssh berzelius1 in Terminal, it generates the correct socket such as: cm-x_jilan@berzelius1.nsc.liu.se:22. After that, I can connect to the server via SSH in a new session without needing a password or verification code.

However, when running the same command in Warp, it doesn't generate the correct socket but one named with a sequence of numbers, as shown below:

Although I can still connect to the server, when I try to connect to the same server in a new session, I have to re-enter the password and verifcation code, which suggests that Warp has issues with the utilization of ControlMaster in my case.

Include shell xtrace output

WARP_DEBUG_MODE=1 ssh berzelius1
(x_jilan@berzelius1.nsc.liu.se) Password:
(x_jilan@berzelius1.nsc.liu.se) Verification code:

There is no other output.

Does this block you from using Warp daily?

No

Is this an issue only in Warp?

Yes, I confirmed that this only happens in Warp, not other terminals.

Warp has an SSH Wrapper that enables features (like the blocks, prompt, completions, etc.) on remote machines requiring the default prompt on the remote machine to be either bash or zsh.

As a workaround you can add command ssh to your Settings > Subshells > Added commands menu, then run command ssh <user@server> to connect to remote session, this will attempt to enable Warp features as a subshell.

You can also try disabling the SSH Wrapper by navigating to Settings > Features. Blocks will stop working but with it disabling, SSH should work as normal.
