I am coming from notepad, and am learning how to work with VS Code.
I am now trying to access my online repertory on the webserver.
I followed up the guide here: https://code.visualstudio.com/docs/remote/ssh
I did manage to access my server through the terminal window.
(ssh user#domain + password).
When connecting, this shows in the log:
"Linux infong-eu27 4.4.246-icpu-061 #2 SMP Thu Nov 26 10:58:41 UTC 2020 x86_64"
This tells me that it is working on Linux.
If I type "Ls", I can see my folders and navigate among them.
So far, so good!
Second phase: Connecting through the remote explorer.
Step 1:
I configured the ssh with the same credentials I used with the terminal.
Step 2:
I am opening the remote explorer, I can see my server's name. I right click on it and select "connect".
Step 3:
I am then asking to choose the system. I am picking Linux as shown earlier when connecting through the terminal.
Step 4: I am entering the same password I used before to connect in the terminal.
Step 5: Infinite loading, or a very long one till I get 2 notifications / errors:
Could not fetch remote environment
Failed to connect to the remote extension host (error time limit..)
That being said, it also says in the bottom left corner, in the "remote window", that I am connected. This does not seems right.
Any chance someone could help?
I am frustrated because it connects in 1s using the terminal, but not in the remote explorer.
UPDATE:
I found this article on medium that paraphrases the official documentation.
https://medium.com/#sujaypillai/connect-to-your-remote-servers-from-visual-studio-code-eb5a5875e348
I managed, through Git bash, to create a ssh pair key, and managed to copy one on my server.
I then followed the instructions on how to set it up on VS Code successfully!
Now, when I try to connect, I am asked for my key pass:
But, when I do: super long loading, and the same error message.
When I looked on my server with a sftp software, I see that VS did manage to connect as files were installed in a VS folder it created:
This is reported in issue 4415 (no answer) and issue 4204
The last one includes:
This might be caused by our new automatic port forwarding feature which scans the remote OS for available ports in order to forward them locally (microsoft/vscode#112843)
This is fixed by PR 113342, for the next 1.54 Feb. 2021 release. That bug is about setting remote.autoForwardPorts to false and... still seeing VSCode auto-forward ports!
Check on your server (while VSCode attempts to connect) if:
the CPU is high
if there are any services running on public port on said server
I solved a similar issue by following the error logs from the remote ssh extension. I had to install libatomic1 on the remote server with
sudo apt-get install libatomic1

I'm using VSCode 1.72.2 with Remote-SSH v0.90.1 on Windows to develop against an AWS EC2 VM running Ubuntu 22.04 LTS. A couple days ago, I was working in my project source folder in /opt/t4/ on the target host. When I was finished, I stopped the VM from the AWS console, forgetting that VS Code was still SSHed in.
When I brought the VM back up, I can reconnect VS Code/Remote-SSH to the host as before, except that I can no longer connect using /opt/t4/ as my working directory. I can use any directory except the one I was using when I disconnected.
I can navigate down to it and work in it if I use /opt/ as my working directory. I can navigate to it by manually SSHing to the remote host. I can create a subfolder in a remote shell at /opt/t4/test/, and then connect VS Code using that subfolder as my working directory. I can see and select /opt/t4/ in the Open Folder dialog in VS Code. But when I try to connect using that working directory, the connection times out with a not-particularly-useful error message:

I tried Remote-SSH: Uninstall VS Code Server from Host from VS Code.
I tried deleting ~/.vscode-server on the Linux host from an SSH session.
I tried Remote-SSH: Kill VS Code Server on Host from VS Code.
I tried Remote-SSH: Kill Local Connection Server for Host from VS Code.
I tried deleting and recreating the host connection details in the local config file from SSH-Remote.
I tried rebooting both local and target hosts.
I tried setting /opt/ as my working dir, then deleting and recreating /opt/t4. I was able to do this, but as soon as I try reconnecting using /opt/t4 as the working dir, VS Code still fails to connect.
I'm... stumped. My suspicion is that there is something corrupt cached Windows-side, but I don't know where to look for that.
Microsoft is aware and working on a fix. There are a variety of workarounds in this thread: https://github.com/microsoft/vscode-remote-release/issues/7324
Thanks to the link from #Mike Barry, I managed to find the local workspace for that target folder and delete it to force it to reinitialize, which cleared the issue.
Deleted C:\Users\me\AppData\Roaming\Code\User\workspaceStorage\[guid]\ and reconnected with no problem.
I'm trying to connect to a server via remote-ssh extension for Visual Studio Code, however, I'm getting the following error:
The vscode server failed to start SSH
Everything is fine on the server-side, and the connection to this host worked fine for a while.
Any suggestions to re-access the server via remote-ssh extension?
After a while, I found a solution that can be useful to others.
In VS Code press:
CTRL + SHIFT + P
Type or select the option:
Remote-SSH: kill VS Code Server on Host...
Select the host name:
And after this procedure, try connecting again to the host.
That worked for me.
In my case it was ssh plugin issue. I updated remote ssh plugin then it worked
wrong proxy setting may cause problem.
If Remote-SSH: kill VS Code Server on Host command not work for you, open settings and clear proxy setting and retry.
Everything is fine on the server-side, and the connection to this host worked fine for a while.
In case it is a simple intermittent network issue, VSCode 1.70 (July 2022) will retry the connection for you (up to 5 times)
See issue 127565 and PR 156444
Retry up to 5 times the initial authority resolving and also retry up to 5 times the initial connection
When connecting to a remote, if the initial connection fails, we will give up. The idea was that retrying would be useless, since the initial setup might have failed.
But it is possible that perhaps it was an intermittent network error.
This is available in VSCode insiders today.
Update the Remote ssh
check file groups belongs to same group if you manually copied .vscode-server
Remote-SSH: kill VS Code Server on Host...
Didn't work for me, so I tried the other option:
Remote-SSH: Uninstall VS Code Server from Host...
It took a bit more time but worked for me!
For a node project I will have to work on a remote server and for that I will use filzilla for file transfer and ssh for console.
I use Visual Studio Code, I installed a remote ssh extension,
I did the hostname and user configurations as well as secretkey,
because before that I had another error The process tried to write to a nonexistent pipe ,
which I finally solved but now after I start ssh and log in with the password in cmd from Visual Studio Code, I get this error bash: powershell: command not found.
I tried one day to search the internet for that error.

I've talked to people who have more experience but within the time limit my advice could be, but I still couldn't solve the error, either it's something from windows or ssh or I don't know.
You are the first time I try to do this in general I used heroku or aws that had some facilities.
I changed host machine in the settings JSON file windows to linux
When you got the option to Select Linux, Windows or Mac did you make sure that you know exactly the type of server you are connecting to. Bcs if you choose the wrong one this error gets thrown.
I am having trouble using the remote-ssh plugin in Visual Studio between machine A and machine B where the key is provided by KeeAgent from a KeePass database on machine A.
Machine A runs on Windows 10 and I have set up the Host (machine B) in Visual Studio Code correctly according to the guide. However, when trying to use the remote feature, I get the following error:
[09:48:32.111] Log Level: 2

where XXX.XXX.XXX.XXX obviously is the correct IP of machine B in my output.
As I mentioned, the SSH key for this machine is provided via KeeAgent and works fine with PuTTy. I am not allowed to store a SSH key in plaintext on machine A, hence the Keepass/KeeAgent solution. I guess this is the Problem, that somehow Visual Studio Code does not work with KeeAgent.
Can I work around this, i.e. by telling VS Code to use plink.exe as SSH client, which works with KeeAgent? Or does VS Code allow the encrypted storage of SSH keys itself, thereby making KeeAgent obsolete? I am new to both VS Code and the remote-ssh plugin, so I'm sorry if my questions have obvious solutions.
Maybe the problem lies elsewhere though. In that case I am thankful for every hint.
Thanks!
Go to Options > KeeAgent, then scroll down to Agent Mode Options and activate Enable agent for Windows OpenSSH (experimental): (default: disabled) Enable an SSH agent socket compatible with the built-in Windows 10 SSH client.
I'm trying to get Remote-SSH working with ssh-agent, from Windows 7 desktop to CentOs 7 server.
I'm using ssh, ssh-add and ssh-agent from the Git for windows package. From the cmd prompt, this is all working fine, I can "ssh-add -l" and see the keys, and I can run "ssh " and it runs with no problems and without asking for password:
C:\Users\gnb>"c:\Program Files\Git\usr\bin\ssh-add.exe" -l
4096 SHA256:zg2IR6OlPwCGP8SzcbriXIQjth5zuDc9rbO6uaNPmcU gnb#VDI028-MEL (RSA)
C:\Users\gnb>ssh vdi ls
Desktop
tsclient
wkspace
C:\Users\gnb>
From within VS-Code, I can't get this to work. Running the exact same ssh-add command from within the VS-Code Terminal does not seem to find the agent:
C:\Users\gnb>"c:\Program Files\Git\usr\bin\ssh-add.exe" -l
Could not open a connection to your authentication agent.
The actual remote functionality in VS-Code more or less works, but keeps stopping to ask for passwords.
What's missing here? Why can the vs-code environment not connect to the ssh-agent?
OK, I've had a few more hours playing around with this and I think I understand what's going on.
It only works from cmd if it is the same cmd window that was used to start the agent. Opening a new cmd window then ssh gets the same msg as starting vs-code from the menu - can't find the agent. It appears that the start-ssh-agent script that comes with git/ssh on Win7 is setting some environment variables or some such that the ssh client needs. This does make sense, Unix ssh-agent acts the same way, but I'm clearly not used to thinking about windows apps in those terms.
It also seems the start-ssg-agent script will set the environment variables to point to an existing agent if one is running, else will create a new agent. So a 2 line batch file
start-ssh-agent
code
will reliably start up VS Code with the ssh-agent. If you name the identity file in the ssh config, vs-code will add they key to the agent when required. Otherwise you need to manually add the key to the agent, or fall back to entering the password all the time.
Suspect the better solution is to be on Win10 and use ssh-agent as a service, which should mean VS-code should find the agent when run from a menu. But I can't test that.
