This is my ssh config.

Warp needs to add the ability to run when you have your own remote command set, until they figure that out a cludge would be for them to add -o RemoteCommand=none to their ssh commands, which would disable your command but let their stuff work.

Hey Folks, 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.

Related docs:
https://docs.warp.dev/features/ssh
https://docs.warp.dev/features/subshells

If those don't work, please let us know.

Adding ssh nor ssh $ssh_host_name to the blocklisted commands does not make it work.

However, running the command in a subshell works:

# Any of these work
"$SHELL" -c 'ssh $ssh_host_name'
bash -c 'ssh $ssh_host_name'
sh -c 'ssh $ssh_host_name'

@dannyneira

Since you have to hard-code <user@server>, this would only really work if you connect to one particular server, correct?

[dannyneira]

@nick-youngblut if you just add command ssh to the subshell menu, you should be able to use any user@server and still see the "Warpify" subshell option.

For me, even if I add command ssh (the actual command with command prefix) to the Settings → Subshells → Added commands, I still get Cannot execute command-line and remote command.

Moreover, I think the following issues are duplicates of this one:

• Remotecommand doesn't work #1761;
• Cannot use RemoteCommand in ~/.ssh/config, error: Cannot execute command-line and remote command. #4466.

@dannyneira command ssh does not work for me. I do not get the subshell features (e.g., auto-complete suggestions).

Running ssh to connect to the head node does work. I'm using:

Host my_slurm_cluster_login_node
  HostName X.XX.XX.XX
  User nickyoungblut
  IdentityFile ~/.ssh/id_rsa

...but logging in to either the head node or any other node via command ssh does not provide the subshell features. An example setup for logging into a non-head node:

Host my_slurm_cluster_node
  HostName X.XX.XX.XX
  User nickyoungblut
  IdentityFile ~/.ssh/id_rsa
  RequestTTY yes
  RemoteCommand sh_dev --mem 8G --cpus-per-task 8    # `sh_dev` is just a bash script wrapper around `srun`

To be clear, I can ssh onto any node with command ssh, but I don't get the Starting Shell... message, and none of the many features of Warp (e.g., blocks or auto-complete suggestions).

For me it works: -o RemoteCommand=none

with config

User deploy

# Prod
Host pam
  HostName am-prod-01.lan
  RequestTTY force
  RemoteCommand cd /var/www/project/current; bash -l;

Before:

ssh pam 'cat config/database.yml'
Cannot execute command-line and remote command.

After:

ssh -o RemoteCommand=none pam 'cat config/database.yml'
