Disabling dynamic port forwarding

Open Aviatorpaal opened this issue 1 year ago • 14 comments

Type: Bug

Attempting to connect to a server which does not allow TCP forwarding (disabled in openssh server).

Dynamic port forwarding disabled in vscode client extension. SSH connects successfully, but hangs when still attempting to setup port forwarding.

"Failed to set up socket for dynamic port forward to remote port 45755: Socket closed. TCP port forwarding may be disabled, or the remote server may have crashed. See the VS Code Server log above for details."

I believe I might be hitting this as well. The cluster I'm trying to connect to does not allow port forwarding.

mathomp4 avatar Nov 01 '24 14:11 mathomp4

Hitting the same error, can connect from terminal but with extension, no luck.

dre5ib avatar Nov 15 '24 08:11 dre5ib

Could someone hitting this today provide their full Remote - SSH logs? Perhaps there is a regression with an unlucky combination of settings

The problematic line in the ~/.ssh/known_hosts file should be removed or commented out.

abzb1 avatar Dec 18 '24 05:12 abzb1

It has nothing to do with ~/.ssh/known_hosts I can ssh to remote host over terminal. TCP port forwarding is disabled on this host, so when I try connect with vscode, I get this:

Port forwarding is disabled on remote host. I have account, but not root access, so I cant change It.

I am having the same issue too

Same problem here, happens occasionally. I have tried to configure it as disabled to workaround it hanging my window, but the configuration seems to be ignored:

[Forwarding server port 65129] Got connection 0
[Forwarding server port 65129] Got connection 1
Failed to set up socket for dynamic port forward to remote port 39049: read ECONNRESET. TCP port forwarding may be disabled, or the remote server may have crashed. See the VS Code Server log above for details.

I use ControlMaster auto and I have manual forwards configured in my SSH config. I am connecting to a local VM over ssh.

To recover I have to fully quit vscode and kill all of my local SSH connections. For me it seems buggy that my user configuration is not being respected (in addition to this hanging my windows which were functioning fine up until they don't):

{
    "remote.SSH.enableAgentForwarding": false,
    "remote.SSH.enableDynamicForwarding": false,
    "remote.SSH.enableX11Forwarding": false,
}

Same problem here, it is not working even after I kill all my ssh sessions.

Port forwarding is disable on one of my remote hosts. Can use this extension to edit files.

This is still an issue, hopefully someone reopens this.

I don't understand it, what a sick policy. It's a bug, but since no one from the development team has addressed it, the application is closed. Who came up with this sick policy of closing submissions? Why is there even an opportunity to report bugs if they are totally ignored?

... And the bot states, it has no recent activity ... The last comment on this topic is just over one month in the past ... How much more recent does it need to be?
