Does your remote have bash on the path?

[minatverma]

Does your remote have bash on the path?

Yes. @ /usr/bin/bash
and it is in the path.

[roblourens]

What happens if you run ssh devde bash?

Does it also exist at /bin/bash?

[minatverma]

Interestingly, it errors out.

bash-3.2$ ssh devde bash
/etc/profile.d/lang.sh: line 19: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory
bash: bash: command not found

Also, the machine where I was able to open remote, does not connect too, it hangs without any error message.

bash-3.2$ ssh qade bash
/etc/profile.d/lang.sh: line 19: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory

however, I am able to get bash running just after logging into the machines.

This is what I have in bash_profile:

.bash_profile

Get the aliases and functions

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

Nothing unusual.

[roblourens]

Ok, kind of strange, not sure how you ended up without bash on the path. What OS? And does /bin/bash exist? I think I need to call that instead of bash on the PATH.

I got the following error:

I tried to run the command:

ssh -T -D 39945 -o ConnectTimeout=15 titan02 bash

it hangs. If I change the -T to -t, it works. maybe a simple replacement in code will fix it?

[jingpengw]

This issue seems only happens in ubuntu 18.04. it works in ubuntu 16.04.

[roblourens]

Please file your own issues. That looks different from the OP's issue.

@jingpengw I had the same error

ssh -T -D 39945 -o ConnectTimeout=15 titan02 bash # not working
ssh -t -D 39945 -o ConnectTimeout=15 titan02 bash # works

There is a way to change that in vscode ?
Thanks !

[roblourens]

Does it work with no -t at all? If not please give more details in a new issue.

[chenqiuyuan]

I met the same error in which the ssh is totally ok. The error message is identical.

[svanschalkwyk]

Same here. Linux Mint 19. New install.
From same server (running VS on the server), always asks for password, then connects.
From remote laptop (Mint 18), times out with this.
"-t" instead of "-T" works.
Does not work without a "t" or "T".
