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.
After trying to solve this for days, I want to ask for help here:
I want to make backups with rsnapshot, which usually runs on a server and manages local backups. In my case, I want to run rsnapshot on my computer and let rsnapshot manage my backups on an externel harddrive. This externel harddrive is connected to my raspberry pi and mounted to my computer with following command:
sudo sshfs -o default_permissions,allow_other,idmap=user,IdentityFile=/home/user/.ssh/id_rsa pi#192.168.0.1:/mnt/externelHdd /mnt/backupHdd
Here, /mnt/backupHdd is the local root for rsnapshots backup directory.
Additionally, I want to connect the external harddrive directly to my computer for bigger backup jobs. For this purpose I wrote a script, which mounts the external harddrive either locally or over network with upper command. Afterwards, it starts the rsnapshot job with sudo rsnapshot daily. When the harddrive is connected locally, everthing works fine. When it's connected over sshfs, I get permission denied errors.
Rsnapshot apperently is not allowed to manage files per sshfs, when the files/directories were created with physical connection (different users: local and rasppi). I tried to solve this with the option allow_other and idmap=user but I think there is more to do. So Im asking you guys: How can I give permissions to rsnapshot?
Thanks for any help!
edit:
I get the following error:
/bin/cp: cannot create directory '/mnt/backupHdd/daily.1': Permission denied
----------------------------------------------------------------------------
rsnapshot encountered an error! The program was invoked with these options:
/usr/bin/rsnapshot daily
----------------------------------------------------------------------------
ERROR: /bin/cp -al /mnt/backupHdd/daily.0 /mnt/backupHdd/daily.1 failed (result 256, exit status 1).
ERROR: Error! cp_al("/mnt/backupHdd/daily.0/", "/mnt/backupHdd/daily.1/")
daily.0 was created when the hdd was connected to my local computer. daily.1 should be created with my hdd mounted over sshfs.
I'm assuming your running rsnapshot as root and root owns the remote backup directory. This command:
sudo sshfs -o default_permissions,allow_other,idmap=user,IdentityFile=/home/user/.ssh/id_rsa pi#192.168.0.1:/mnt/externelHdd /mnt/backupHdd
Is not going to work out as I think you are intending. Even though you are using sudo on the local side of the connection, your still SSH-ing in as "pi" meaning everything done on the far side of the connection is done by the user pi. No option to sshfs can change this fact. You'd need to enable root login and then ssh in as root, or at least some user that has full R/W access to that drive.
Im trying to setup vscode with the remote developement extensions on a second pc. While it works on my main one it doesnt on the second one. Tried reinstalling vscode, extensions and using older versions but nothing works.
When trying to connect it cancels after chosing the os. So I cant even type in the password.
I set it up in the exact same way as with the other pc.
Any ideas?

Depending on the system you are in, when you first try to connect, a vscode-server will be set up and configured on your server.
In linux that can be in /Home/<user>/.vscode-server
If you are on windows, check what that is.
The first solution is to try the extension command: Remote-SSH: kill VS Code Server on Host
Open the command pallet (CTRL + SHIFT + P or COMMAND + SHIFT + P (mac) ).
And type Remote kill :
Then try to connect again! (That will kill the server on the host! Which will make it start again on the next try)
If that doesn't work, and things are still failing:
Delete, rm
Then a good solution that can work is: to connect to your server through terminal (vscode terminal, gnome-terminal, whatever). Then go and remove /Home/<user>/.vscode-server
Try to connect after that. At the attempt the server will be re-installed completely anew, chances are it will work. (I did that and it worked for me, so whatever that was going wrong on the vscode-server: just start all over)
But again: you will lose things, config, meta data, etc. (because you start anew).
Update:
As stated by #natevw in the comments:
I found that removing only the .vscode-server/bin subfolder helped straighten things out and afaict kept my data/settings.
Removing only vscode-server/bin seems to work well, and the config, metadata, etc. remains untouched.
I downgrade Remote-SSH plugin to 0.51.0, rm -rf $HOME/.vscode-server on the remote machine. Connect again, VSCode will download and install a new .vscode-server. Then upgrade Remote-SSH plugin, everything works.
One way worked for me is, by adding this line in the vscode settings (JSON) file.
"remote.SSH.useLocalServer": false
I met the same problem. After I did these steps, it works:
on the remote server:
rm -rf ~/.vscode-server
rm -rf ~/.vscode
On the local VS code:
reinstall remote-ssh
In case all the above fails, here's how I fixed my issue.
First, I was able to SSH into my remote server (Ubuntu 22.04, Raspberry Pi 4, arm64) using a simple bash terminal. So I logged in using my terminal (macOS), and I went to
cd $HOME/.vscode-server/bin/WHATEVER-HASH-YOU-HAVE/
In this directory, there is a file named server.sh. I tried running this script, and I got the following error:
./node: error while loading shared libraries: libatomic.so.1: cannot open shared object file: No such file or directory
The issue was clear: there was a missing shared library on my system. Either Node.js now requires that or the new version of the SSH-Remote extension; I don't know. I did not spent the time to dig into those specifics.
But to fix that, I simply did:
sudo apt-get install libatomic1
That installed the missing shared library.
After that, I delete $HOME/.vscode-server:
rm -rf $HOME/.vscode-server
and tried again connecting using VSCode. It worked!
Hope this can help someone like me, for whom all other options failed.
Issue: while trying to ssh connect to Linux(remote machine) using vscode.
Solution: remove/delete the bin folder inside .vscode-server and then reconnect to the remote machine
In remote server:
remote_name:~$ rm -rf ~/.vscode-server/bin
*reconnect to remote machine*
It turns out that my fish was a obstacle for vscode server.
Then I tried
chsh -s /bin/bash
And works fine.
I worked adding \\ in the path of the .config
I share the steps
Go to .config settings
select configuration
add double \\
Just deleted old host information from ssh settings file and problem solved.
I had faced this issue when I tried to connect to a Linux server from a windows laptop.
It was using the wrong fingerprint.
It worked for me after removing the line related to that server from $HOME/.ssh/known_hosts
I ran into the same issue, it got fixed when I updated the path of the IdentityFile from 'ssh_key' to '~/.ssh/ssh_key' (the entire path I mean) so that the VS code could recognize it.
Restart remote machine worked for me (after trying all the previous answers with no luck).
Giving you the oldest trick of the book:
restart
It worked for me and I laughed hysterically for exactly 57 seconds. Happy reconnecting to the server my dear Coder!
I could not connect to the server, my issue was the remote server was full
check with the command df -h if the disk is full !
Here is an alternative for Remote SSH, pls check my answer at: https://stackoverflow.com/a/68046111/13089935
TLDR:
We can use a web-based VS Code that is installed on the server directly.
In regard to Uptime.
I want to install the agents on solaris machine remotely through putty.
Now for that, I have established(logged in) a connection to that system successfully.
following this, my next step would be to "Using a file transfer method such as FTP, transfer the archive containing the Agent to the system on which you want to install it. You should copy the archive to a temporary directory on the system."
Now my problem is that i am unable to transfer the archive containing the agent, to the system on which i logged in through putty.
I have searched this command to transfer the files rcp machinename:source destination
here my machine name is:
\uptime-share.uptimesoftware.com\css\Releases\Agents\Solaris
source : uptimeagent-7.2.1-solaris-sparc
destination : 172.20.98.14/tmp
but after using this command i get the message connection refused.
Could someone help me to do this.
I used this command
rcp 172.20.32.11:/css/Releases/Agents/Solaris:uptimeagent-7.2.1-solaris-sparc 172.20.98.14/tmp
I am currently taking an operating systems class and I need to use qemu to run a small operating system that my professor provided. I am trying to use qemu within an ubuntu 12.04 virtual machine on virtualbox on my macbook air 5.2. I know the problems I am having probably have to do with nested virtualization but the specific error I get when I try to run qemu is:
Could not access the KVM kernel module: No such file or directory
failed to initialize KVM: no such file or directory
Back to tcg accelerator.
qemu does start up the os but the window flickers quite a lot and I would like to fix the KVM problem if possible. I've done research but I can't find a solution I can understand or that works so any help would be greatly appreciated.
Also for the ubuntu virtual machine in virtualbox I have both Enable VT-x/AMD-V and Enable Nested Paging checked under Hardware Virtualization. I've also tried using
modprobe kvm-intel
and I get this error:
FATAL: Error inserting kvm_intel (/lib/modules.3.5.0-22-generic/kernel/arch/x86/kvm/kvm-intel.ko): Operation not permitted.
In my case, the virtualization was disabled.
So sudo modprobe kvm-intel kept giving me the following error
could not insert 'kvm_intel': Operation not supported
I just had to go in the BIOS and enable Virtualization.
Try with sudo modprobe kvm-intel.
In order to have the module automatically loaded at the startup of the virtual machine, do the following:
Edit the corresponding file from the shell with sudo vim /etc/modules.conf
Possibly enter your username password.
Press the key G to go to the end of the document and then o to begin inserting.
Write kvm-intel and press Enter, producing a new line.
Press Esc to return to the Normal mode of vim. "--INSERT--" will disappear from
the bottom.
Save the file and exit vim by writing :wq.
You are done. Try to reboot and load the nested virtual machine.
