I connect to a server within Visual Studio Code using SSH ("Remote-SSH: Connect to Host..."). When working in the terminal within VS Code, the command code <file> results in opening the file in VS Code of the client (therefore on my screen). Now let's suppose I establish another SSH connection from the current session to a workstation within the network of the server using ssh <some workstation>. When I now try to open a file in VS Code using code <file>, nothing happens.
My questions are:
Since the last code <file> mentioned didn't open anything on my screen, is it possible that VS Code did open on any other screen connected to either the server or the workstation?
Is there any possibility to open the file within my VS Code?
As for your first question:
There's is NO WAY your action could have opened a window on any other screen than yours. For that to happen you'd have to "link" your ssh session to that screen, which would require a bunch of intermediary steps.
Now for the second question:
Yes its possible (and pretty easy). BUT you will have to open another session of VScode that will connect to the "workstation" through the server.
Currently, to connect to the server, you probably had to add these lines to your ssh config file:
Host MyServer
HostName adress.server
User username
To open a session in the workstation, through the server, you should add these lines:
Host MyWorkstation
HostName workstation.adress.within.network.of.the.server
User usernameInWorkstation
ProxyJump server.adress

SETUP
I have a windows 10 PC connecting to my linux server (ubuntu 18.04.2). I run/edit code on my powerful server by remotely accessing the server through VS code's ssh ability. It is super convenient to edit my code on the server with VS code...
THE ISSUE
Visual Studio code won't connect to my Linux server. What is weird is that I am able to ssh into the server from the terminal within VScode by just literally typing ssh <username>#<server-hostname>
However, when I do the Remote-SSH option within VScode then it does not want to connect to the server...strange...
Here is how I remotely SSH into server with VScode built in functionality (marked with red rectangle). Also part of this screenshot is my config file, which I have triple checked as correct (IP address and .ssh/id_rsa_gpu_1_solarpv_ssh location)
HERE IS THE ERROR OUTPUT
MY ATTEMPTS
I have made sure that the config file is setup correctly and that the IP address is correct.
I have ensured that the server's IP address is also in the 'known_hosts' file located at /Users/.ssh/
I even generated my own private key for SSH connection as advised by the great documentation here: https://code.visualstudio.com/docs/remote/troubleshooting#_quick-start-using-ssh-keys
Still getting the error of failed to create hard link...
With all of my back-end stuff done right, I am absolutely clueless regarding why this is an issue.
After spending literally 9 hours on this issue...here is the answer:
When you launch VScode and remotely access the linux server, the linux server is instructed to download and install a vscode server so that you (on the other side) can remotely connect to the server.
If the server does not have internet just make sure the following setting is ticked
This allows the remote server (without or with internet connection) to get the vscode server running.
To eliminate the "failed to create hard link error" go to the directory mentioned by the error, which in this case on linux server is
navigate to /home/<username>/.vscode-server/bin/0ba0ca.../
then remove/delete the hardlink file and target file which also has
the same name as the directory.
Then just attempt to remotely access your server again through
vscode and all should be fine
Here is also a discussion regarding the issue...if you still have problems https://github.com/microsoft/vscode-remote-release/issues/2507
I solved this by enabling the option Lockfiles in Tmp:
i just deleted the whole library and it works, i don't see anything wrong with doing that.
rm -r /path_to_project/.vscode-server/
if i'm wrong feel free to correct me :)
Try this
Just in case others need to try the same here is the detail
ctrl-shift-p and choose:
Remote-SSH: kill VS Code Server on Host...
Chose the host name
Selected the platform type (linux)

worked for me.
I'm trying to connect to an admin server in WLST using config and key files. There are no error messages but I am prompted for a username and password. These files were created (by another developer who is long gone[1]) with the storeUserConfig() command. My call to connect looks something like this: connect(userConfigFile=configFile, userKeyFile=keyFile, url='t3://somehost:7031')).
Is there some restriction in using these files, such as it can only be used on the host where created, or it needs access to the domain's boot.properties file?
Note: I'm trying to connect to an admin server on a different host and non-standard port (e.g. not 7001). The server I am running WLST on and the remote host are the same version of Weblogic.
Some of the things I have tried:
verified that these files appear correct, the key file being binary data and the config file having a line for "weblogic.management.username={AES}..." and "weblogic.management.password={AES}...".
verified that there is a server on the specified port by entering a known login and password that is successful
specified the admin server in the connect parameter
turn on debug(true); the only output is <wlst-debug> connect : Will check if userConfig and userKeyFile should be used to connect to the server and another line giving the path to the userConfig file
turn on Python logging in jython with -Dpython.verbose=debug; nothing relevant to decryption operation
Munging the key or the config files generates no error messages and behaviour as above
[1]: These files are still used today by other existing WLST scripts. However, these scripts are so convoluted and deliberately obfuscated that they are very difficult to reverse-engineer how connect() is being called.
You do not need to access to the domain's boot.properties file. You just need to make sure the configFile and keyFile pointing to the right files. FYI, here is one of the commands we are using:connect(userConfigFile='./user.secure',userKeyFile='./key.secure',url='t3://somehost:7001')
Have you check the network connectity that might be having a firewall in between that troubling you, check the traceroute from the script machine to the Remote machine. Recently I have faced simalar issue. once the routing table updated with allow the WL admin server port everything got set.
Hope this could helps you!
I had this problem too. In a script, I exported the Linux variables userConfigFile and userKeyFile. Then I connected by running:
url='t3://localhost:7002'
userConfigFile='$userConfigFile'
userKeyFile='$userKeyFile'
connect(userConfigFile=$userConfigFile, userKeyFile=#userKeyFile, url=url)
That all worked in a script, but would not work interactively. I changed to doing the following:
url='t3://localhost:7002'
userConfigFile='/users/me/weblogic-2014/weblogic-admin-WebLogicConfig.properties'
userKeyFile='/users/me/weblogic-2014/weblogic-admin-WebLogicKey.properties'
connect(userConfigFile=userConfigFile, userKeyFile=userKeyFile, url=url)
And that worked interactively.
I'm having trouble connecting to Navicat using an SSH Tunnel and seem to have all my ducks in a row, so wondering if anyone else who had done this has had success:
I set up a normal (TCP) user and checked the connection (host, port, user, password, and remote access ip added in cpanel) to make sure it worked.
As per the instructions, I then went to the SSH tab and enabled it ([x] SSH Tunnel).
I added the same IP for host, then 22 for port, then added root as user, selected password as authentication and then entered the root password.
I keep getting a host.mydomainame.com cannot connect to this mysql host.
I know it is working because:
a) if I use the wrong user/pwd I simply get a 'could not create tunnel' error
b) my host confirms that an SSH connection IS created the moment I connect with the correct root/pwd combo (even though the error message is generated on my side)
BTW as per Navicat I ensured that AllowTcpForwarding is set to yes.
I also confirmed using bithive I can connect to the same server from the same IP with the same user.
Figured this out so thought I'd update so anyone else having issue can make this work. Answer turns out to be pretty basic.
The 'General Tab' where you set your MySql User has to have localhost, not the hostname or ip as it usually does, since the SSH Tunnel Tab creates the connection to that host first.
In my case, I used a PuTTYgen -> Load an existing private key file -> Conversions -> Export ssh.com key and that solved my issue!
I have set env.user and env.password,but when I use:
run('ssh-copy-id -i $HOME/.ssh/id_rsa.pub server1')
it still asks me for the password,why?
env.user and env.password are used to ssh to remote server and then run the command inside run () at the remote server.
They are not used for the remote command itself (running in the remote server).
So ssh-copy-id doesn't know anything about the user or password.
If this is not what you mean, I would advice you to edit the question and make things more clear, like providing more context of what you are trying to accomplish: pasting the function that contains this 'run' for example.
I have created a VB.NET program using windows forms. The program runs on a remote PC and displays information on a screen. The computer does not even have a mouse or keyboard connected to it. The program shows the information based on the file that is loaded.
I want to be able to change this file remotely to another file that is already on the remote PC. I can't use a graphical remote desktop client as we have very limited bandwidth.
So, my idea is to change the file using the command prompt (I think I'll need something like SSH). I'm not sure how to do this. Should I use something like this and load DosModule first:
Module DOSModule
Public Sub Main()
Console.Write("First, start with Command Prompt processing ...")
Dim myWinForm As New WinForm
Application.Run(myWinForm)
End Sub
End Module
How would I then read commands that is send to the program? I also only want one instance of the program running.
Thanks
You have 2 options. The first is a custom program that WILL require some network programming, like it or not. I would suggest creating either a Command-Line batch file or else a PowerShell script, then creating a program to transfer the script to the remote computer and execute the script.
The second option and the one better suited for you would be to download an SSH server. An SSH server will essentially open a command window and pipe the input and output over to a telnet client running on your machine. If you are running a version of Windows Server, an SSH server comes with Windows Server. Otherwise, you can download one for free here: http://www.freesshd.com/
Once you install the SSH server, you simply use telnet, from a command prompt, to link up with your remote SSH server
