Operating System and Version

macOS Ventura 13.1

Warp Version

v0.2023.01.24.08.03.stable_01

I have tried commenting out my system & user rcfiles and warp still will not bootstrap

[X] Yes

Screenshots

Screenshot are hard to catch because with one of those option some script lines are run just like commands on the prompt.

Below is the xtrace output of the oldest of my servers because on my youngest ones the output is too long (seems to be an infinite loop) Using Warp it's strictly impossible To this server with any of -v, -vv, -vvv or none of these options. The resut is always the same : "exec request failed on channel 1"

Include shell xtrace output

Does this block you from using Warp daily?

Yes, this issue prevents me from using Warp daily.

Thanks for submitting @Wulfaz , It may be an issue with the different version of SSH on the remote servers, if they are on the same version does the issue persist?

Wulfaz commented 1 year ago

Hello @dannyneira,

Thank you for you answer! I'll share with you a Loom video of my testings. Nota: everything is fine on all my servers if I'm not using the Warp SSH wrapper!

Some info: 1) the sshd on the 1st server (named "karotz") is a Dropbear v2014.66 on a Busybox v1.24.0 (on an ARMv4TL: Linux karotz 2.6.28-pragmatec -g53e06b1-dirty #1 Tue May 31 17:50:18 CEST 2011 armv4tl GNU/Linux) Quite old and not powerfull (that's why I cannot change the sshd on this device) - without the SSH wrapper everything is fine: I can even connect via my rsa key => command "ssh karotz" with options -v, -vv or even -vvv are still not able to connect 2) the sshd on the 2nd server (named "nabaztag") is a OpenSSH_7.9p1 on Raspbian-10+deb10u2+rpt1 (Raspberry PI W) => command "ssh nabaztag" with option -v, -vv or -vvv cause some trouble you can see in the following loom video.

Here the Loom video link: https://www.loom.com/share/4e023439364842d28e12ba4428a50e12

Thanks again Danny

Not sure if this is the same issue, or not. When I connect to ssh server, the default shell for the server uses nushell. This causes ssh connection to close immediately. Running from macos terminal everything works as expected. Guessing warp tries running some scripts, and the "export" keyword triggers the closing.
