how to set tssh as vscode default tools when create a new remote window？

[wyjBot]

I have tried change ”remote.SSH.path“ to "C:\Users\wyjbot\AppData\Local\Microsoft\WinGet\Links\tssh.exe" .but it not work

[lonnywong]

What is your purpose of using tssh in vscode?

If you want to use trzsz in the vscode terminal, modifying remote.SSH.path is not supported. You can open a local shell first, and use tssh in the local shell to log in to the server, which will support trzsz.

If you want to use tssh's automated-interaction feature to log in to the server, you need to write a script and change remote.SSH.path to the script.

• tssh.sh ( on MacOS, Linux, etc... )

#!/bin/bash

# vscode requires -V to output OpenSSH
if [[ " $@ " =~ " -V " ]]; then
  echo "OpenSSH"
  exit 0
fi

# replace -v with --debug
args=()
for arg in "$@"; do
  if [ "$arg" != "-v" ]; then
    args+=("$arg")
  else
    args+=("--debug")
  fi
done

# call tssh
tssh "${args[@]}"

• tssh.bat ( on Windows )

@echo off
setlocal enabledelayedexpansion
rem vscode requires -V to output OpenSSH
for %%A in (%*) do (
    if "%%A"=="-V" (
        echo OpenSSH
        exit /b 0
    )
)
rem replace -v with --debug
set args=
for %%A in (%*) do (
    if "%%A"=="-v" (
        set args=!args! --debug
    ) else (
        set args=!args! %%A
    )
)
rem call tssh
tssh %args%

Is this normal on your win? I still can't bring up win11 file browser to upload. I suspect that vscode remote.SSH.path does not take effect

[lonnywong]

If you want to use trzsz in the vscode terminal, modifying remote.SSH.path is not supported.

trzsz ( trz / tsz ) is not supported even you set remote.SSH.path to tssh.bat.

After you log in to the remote server in vscode, execute the following command in Windows PowerShell:

Get-WmiObject Win32_Process | Where-Object { $_.CommandLine -like '*tssh*' } | Select-Object ProcessId, CommandLine

You will see the output similar to this:

tssh -T -D 55648 xxx bash

When you open multiple remote terminals in vscode, the number of ssh processes will not increase.

That's because each terminal in vscode is implemented by vscode itself through -D dynamic port forwarding.

tssh cannot capture the input and output of each terminal in vscode, so it cannot support trzsz.

[wyjBot]

fine.

1. I use my company's file transfer tool called "ift". it could use in vscode, I don't know detail about how it execute. the problem is it only available for company‘s server and need Employee authentication.

2. just for using automated-interaction tssh.bat. it report below bug.

[lonnywong]

What will be the output of executing D:\tssh.bat -V in PowerShell?

[wyjBot]

OpenSSH

[lonnywong]

The weird thing is that vscode will report an error spawn EINVAL.

It may be a permission issue, can you try C:\tssh.bat ?

[wyjBot]

even i directly run it in vsocde bottom terminal：

PS C:\Users\wyjbot> C:\tssh.bat -V                           
OpenSSH
PS C:\Users\wyjbot> D:\tssh.bat -V
OpenSSH

[lonnywong]

The output OpenSSH is as expected, I mean try setting remote.SSH.path to C:\tssh.bat.

1. I use my company's file transfer tool called "ift". it could use in vscode, I don't know detail about how it execute. the problem is it only available for company‘s server and need Employee authentication.

The ift may not be implemented through the ssh connection, but through other connection and authentication.
