Configuration

Blink 17.2.1.865 iOS 17.2.1

Describe the bug

Sending a custom environment variable (via SendEnv) (such as LC_DEVICE) is lost when connecting over mosh. The variable is successfully set over SSH. Steps to reproduce:

1. Set SendEnv in .ssh/config (or host SSH config):

SendEnv LC_DEVICE

2. Set env in host .blink/profile:

LC_DEVICE=test

3. Confirm its set:

blink> echo $LC_DEVICE
test

4. Confirm its set over ssh:

blink> ssh host
$ echo $LC_DEVICE
test

4. Try over mosh:

blink> mosh host
$ echo $LC_DEVICE

no output

Expected behavior

For SendEnv variables to behave the same over mosh as they do on ssh

As a workaround, you can use --ssh option: mosh --ssh="ssh -o SendEnv=LC_DEVICE" [email protected]

Can this be set in the Hosts config, in order to not have to type it manually for each host? I tried using it in the Host - name - Mosh - Command but this just gives an error.
