why ssh connection timed out in vscode? - ssh

I installed git instead of openssl to use Remote-SSH in VSCode.However,after I completed the config document and tried to connect to the remote host.I failed. The error info is showed in the below pic.error info

I had the same problem but the above solutions didn't work with my setup,
but the following setting did work:
"remote.SSH.useLocalServer": false
I got this solution from github reported issues and fix

In my case, the problem was caused by a too long authentication process on the server-side.
Solved it by extending the Connect Timeout from 15 to 30 seconds.
Instructions:
open your vscode Command Palette (via keyboard shortcut or from the
View menu).
search for the Remote-SSH: Settings.
scroll till you find the Connect Timeout.
change it to a longer duration than 15 secs.

key F1
Remote-SSH: Settings
Connect Timeout: from 15 seconds to 60 seconds solve my connection issue

You can try the following approaches:
ssh to your remote server. Then run the following commands to clean data folder and bin folder under .vscode-server folder on the server:
cd ~/.vscode-server
rm data/* -rf
rm bin/* -rf
If step 1 does not work, ssh to your remote server and delete the entire .vscode-server folder with the following command:
rm -rf ~/.vscode-server
Please note that this will also remove the extensions that you installed on the server.
Downgrade the version of the remote-SSH extension in vscode. Look up the extension in the vscode interface, right click on that, and you will find the option "Install Another Version ...". Install the previous version of the current one. If it does not work keep downgrading the version.

I had the same problem before, I solved this by deleting "terminal.integrated.inheritEnv": false inside ~/.config/Code/User/setting.json

I found the solution here in this thread from user oreilm49:
https://github.com/microsoft/vscode-remote-release/issues/1137
in vscode settings :
search conpty and uncheck it

I had same issue, my problem was solved after changing settings in the json file:
I removed "terminal.integrated.inheritEnv": false inside ~/.config/Code/User/setting.json
I added "remote.SSH.useLocalServer": true inside ~/.config/Code/User/setting.json
It worked for me after so many different trials

This might be a very foolish solution but it actually works for me, so I will write it down in case any other people get into the same problem.
I made modifications to the config file for SSH, then all the trials for connection ran into the error of 'Connecting SSH timed out'. I tried many possible solutions but none of them solved my problem.
Then I just closed the VScode and restarted it. Then everything works.

I had a case of this. I my client (local computer) is a Mac, and I was connecting to Linux host. I just went to the setting "Remote Platform" under Remote.SSH settings, and explicitly told it that I am connecting to a Linux remote. After this, it started to work.

I had this issue because of version missmatch of client and server. After updating both to the same version, it worked for me.

The issue with me was timeout at first. I tried increasing the timeout in settings but then later found the issue was with "tar".
The vscode-server.tar.gz (probably a little change in the file name) was not able to install due to tar not being present in my host.
So I installed tar in the host as "yum install tar"
And then tried reconnecting to the server and it worked

Connection to SSH from a pipeline in Azure DevOps is still not working

I saw few other posts (in particular this one) about it but there are from last year. I still have this issue right now. I opened the Preview features from the User settings but I can't turn off this feature.
My pipelines use SSH connection to run some commands on a virtual machine (basically, pull a Docker image).
All my pipelines are failing. How can I fix it or update the SSH connections?
Update
I set up the Service connection
and I use it in my pipelines with this YAML code:
- task: SSH#0
displayName: 'SSH: stop shinyproxy'
inputs:
sshEndpoint: $(server)
commands: |
echo $(pwd) | sudo -S docker stop shinyproxy
failOnStdErr: false
continueOnError: true
All pipelines, new and old, get the same error

I have never had this issue before.
Based on the other post, highlighted by Antonia, the solution has to be applied on the Ubuntu machine.
To fix it, open Terminal and edit /etc/ssh/sshd_config and, at the end of it, add this line
/etc/ssh/sshd_config
After that, restart. It is working for me.

How to fix vagrant up error related to NFS issue?

I ran into a very strange issue this morning. When I rebooted my machine, and tried to run vagrant up, I get this error;
==> default: Mounting NFS shared folders...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
mount -o vers=3,rw,tcp,nolock,noacl,async 10.0.1.1:/Users/me/code /vagrant
Stdout from the command:
Stderr from the command:
mount.nfs: requested NFS version or transport protocol is not supported
I didn't change any configuration settings, or update my machine or anything. Of things I know, nothing has changed. What gives? Anyone have any ideas as to what the issue is and what I can do to fix it?
For anyone that runs into this same issue and none of the other solutions you find seem to work, my issue was 127.0.0.1 localhost missing from my /etc/hosts file. Not sure how or why it went missing, but when adding this back, it fixed the issue.

VSCode Remote-SSH Cannot Connect

I'm trying to use the Remote-SSH extension to edit files on a Linux server from my Windows 10 development machine. Normally, I log into the server using VNC and edit files locally OR I use WinSCP to pull the files to my development machine and copy them back over when done. The Remote-SSH extension seems to be the answer to this inefficiency.
I can SSH just fine using Putty or using Git Bash, but Remote-SSH fails to connect. There's some hints in the error message, but I'm not sure how to interpret them.
Here is my SSH config file (redacted) and the error I receive (redacted):
Config:

VSCode Remote-SSH error
There are there are three ways you can try. I know the problem is annoying.
Check your vscode is local window or remote window. Then, check
remote-ssh setting. (Make sure Local Server Download is auto && Use
local Server is marked.).
Remote SSH:Path . you can switch to local ssh or git/ssh
Try to update or revert remote-ssh.(Version 0.50 can connect to server host stably, I found. This one is very useful.
Maybe you just select 'Linux' instead of 'Windows' though you are using Windows when you got the option to select Linux, Windows or Mac.
Since you are connecting to a server and not your own computer, the type of server you are connecting to is most likely Linux.

Vagrant GuestAdditions issue

Host OS: Windows 10
Vagrant: 2.2.4
VirtualBox: 6.0.6 r130049
When I run vagrant up, it prints this error message:
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
setup
Stdout from the command:
Stderr from the command:
bash: line 4: setup: command not found
The machine can be booted normally and SSH from my host to Virtual machine is OK but the synced folder is not working. I know this may not be a critical issue but still feel frustrated as I use my host machine to develop codes and "sync" these codes so that they can be loaded in my virtual machine.
Any advice is highly appreciated.
ps: When I boot a full UI virtual machine (different from my above mentioned) from my VirtualBox directly, it seems OK to have a "sync" directory and the VBGuestAdditions can be installed without errors.
It is a bug in VirtualBox 6.0.6 and it still exists in 6.0.8. The solution is to downgrade your VirtualBox itself and the Guest Extensions to 6.0.4.

dotcloud push on cygwin fails with "rsync error: unexplained error (code 255)" (similar with git and hg)

Though I have followed the usual steps for using the dotCloud CLI under Cygwin, dotcloud push fails in all cases: --rsync, --hg, and --git.
I am on Windows 8 and Cygwin.
How can I push successfully?
Sample output:
me#host /cygdrive/d/project
$ dotcloud push --rsync
==> Pushing code with rsync from "./" to application myapp
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at /home/lapo/package/rsync-3.0.9-1/src/rsync-3.0.9/io.c(605) [sender=3.0.9]
me#host /cygdrive/d/project
$ dotcloud push --git
Permission denied (publickey,password).r from "./" to application myapp
fatal: The remote end hung up unexpectedly
me#host /cygdrive/d/project
$ dotcloud push --hg
==> Pushing code with mercurial from "./" to application myapp
abort: no suitable response from remote hg!
Error: Mercurial returned a fatal error
You may be running into a bug in Cygwin's group permissions. Vineet Gupta gives a workaround in his blog. The problem comes from the very strict permissions expected by ssh around the keys, and the solution is to set the permission on the ssh key properly (to 600, rw by owner only). Cygwin seems to need the group to be added manually.
Updating the steps to get the dotCloud CLI installed, including setting the permissions, leads to:
Start the Cygwin Setup.
Select default choices until you reach the package selection dialog.
Enable the following packages:
net/openssh
net/rsync
devel/git
devel/mercurial
python/python (make sure it’s at least 2.6!)
web/wget
After the installation, you should have a Cygwin icon on your desktop. Start it: you will get a command-line shell.
Download easy_install
wget http://peak.telecommunity.com/dist/ez_setup.py
Install easy_install
python ez_setup.py
You now have easy_install; let’s use it to install pip:
easy_install pip
Now install dotcloud (the CLI)
pip install dotcloud
Set up the CLI with your credentials. This will also download the ssh key.
dotcloud setup
New Step Update the permissions on your dotCloud key:
chgrp Users ~/.dotcloud_cli/dotcloud.key
chmod 600 ~/.dotcloud_cli/dotcloud.key
Now you should be able to dotcloud push
If you have multiple dotCloud accounts, then you will need to repeat this process for each account, since each account has its own key. Also note that you shouldn't have to set these permissions manually, but it seems like the group ownership is sometimes the wrong default in Cygwin. Linux and OSX don't seem to show this problem, though the permissions must be 600 for all OSes, so it is worth checking.
