Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

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

Hi @unbreakabl3 Sorry to hear about this blocker. Please try using /usr/bin/ssh directly to connect to netapp, as well as make sure that the default shell on the netapp is bash, zsh, or fish. If none of those work, I recommend you disable the SSH wrapper as a workaround. Please see more in our docs. https://docs.warp.dev/features/ssh#troubleshooting-ssh. If we have any updates we'll post it on this thread.

To anyone else facing this issue, please add a :+1: to the original post at the top or comment with your details, and subscribe if you'd like to be notified.

Hi, @dannyneira. Disabling the SSH wrapper as a workaround did the trick. Regular /bin/ssh did work as well.

Not sure if it's possible to change the shell on NetApp in general. But in any case, there are many use cases, where it's not possible to change the shell, just because the administrator using some modern new cool terminal 😁 (for example, validated health, banks, or similar environments). Maybe it will be not a bad idea (if you want to cover more customers, especially Enterprise) to make this wrapping feature detect automatically after the basic SSH connection is established if it's going to work or not. If so - enable the wrap feature automatically on the fly. If not - keep it disabled and notify the user.

Otherwise, the user should remember to switch it off each time before connecting to some "unsupported" system and re-enable it after. I would guess, that in that situation, there are two solutions only:

1. keep the wrapper always disabled (makes this cool feature useless)
2. use another terminal...

Same problem here! Warp version: v0.2024.04.16.08.02.stable_00

Trying to ssh into remote host of my backend service: ssh -l '//user:root//configuration_id:my_service#my_service_vla-1713358457382' host.name.com

And getting the following error:

command ssh indeed helps as a workaround
