visual studio code remote ssh over ssh proxy

问题

I am trying to use vs-code's remote-ssh extension to connect to a server over a ssh tunnel. The server is part of an internal cluster that does not have a public ip address, and I connect to it via a proxy in the cluster using the method outlined in link:

# ~/.ssh/config
Host internal*
User root
ProxyCommand ssh user@firewall 'nc %h %p'

When I try to connect to the internal server, I get the following error dialog:

Could not establish connection to "internal-server". The process tried to write to a nonexistent pipe.

The output window's log:

How can I use vs-code's remote-ssh to connect to computers behind a proxy/firewall?

回答1:

For anyone running into the same problem, I solved it by giving the absolute location of ssh, eg:

ProxyCommand C:\Windows\System32\OpenSSH\ssh.exe -W %h:%p server

There can be two reasons till now which I've explored.

You are facing this error because of misconfiguration/conflict in/of your ssh file. What worked for me is , I am having directory "C:\Users\gur51262" which is having ssh configuration but there is another directory also which is having file "ssh_config" on path "C:\ProgramData\ssh" which is may be creating conflict with it .

So I have only configured file which is present on this path "C:\Users\gur51262" and I've omitted the content of other file which is present on path "C:\ProgramData\ssh".

Also make sure you are following syntax of config file , if there is any. Like

Host host203
  HostName 172.19.51.203
  User root

Solution is for windows7.

There are chances of conflicts in ".ssh/config" file. There may be a duplicate entry of hostname , like below
```
Host 172.19.51.212
  HostName 172.19.51.212
Host 172.19.51.212
  HostName 172.19.51.212
  User root
```
