I wanted to launch the jenkins which is installed through docker automatically in browser.. im working on windows os. in docker base os is ubuntu.. then i used solution from this link1.now im getting following error when i ssh using -v command i find that "read_passphrase: can't open /dev/tty: No such device or address"
by going through many websites i have created ssh file through windows using gitbash it contains id_rsa,id_rsa.pub,known_hosts files.
Now what should i do to launch the jenkins file in browser which is build using docker
I'm just going to address the error message you pasted for now.
ssh is trying to get keyboard input for the passphrase on your private key, but can't open the terminal correctly. Are you running the ssh command directly in the terminal, or from a script? If not, try running ssh directly. If you need to run ssh from a script:
Maybe try with keys that don't have a passphrase.
If you can use ssh-agent: Run eval $(ssh-agent), then run ssh-add and enter your passphrase. ssh will no longer prompt for a passphrase now.

Windows 11 with wsl2 ubuntu-22.04.
In Windows Terminal I open a PowerShell window and start wsl with command:
wsl
Then I start the docker daemon in this window with the following command:
sudo dockerd
It prompts for the admin password, which I enter and then it starts the daemon.
Next I open a new PowerShell window in Windows Terminal, run wsl and run a container to verify everything is working. So far so good.
Now I want to login to Azure Container Registry with the following command:
az acr login -n {name_of_my_acr}
This returns the following error:
You may want to use 'az acr login -n {name_of_my_acr} --expose-token' to get an access token,
which does not require Docker to be installed.
An error occurred: DOCKER_COMMAND_ERROR
error during connect: This error may indicate that the docker daemon is not running.:
Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json":
open //./pipe/docker_engine: The system cannot find the file specified.
The error suggests the daemon is not running, but since I can run a container I assume the deamon is running - otherwise I would not be able to run a container either, right? What can I do to narrow down or resolve this issue?
Docker version info using docker -v command:
Docker version 20.10.12, build 20.10.12-0ubuntu4
An error occurred: DOCKER_COMMAND_ERROR error during connect: This error may indicate that the docker daemon is not running.: Get"http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json": open //./pipe/docker_engine: The system cannot find the file specified.
The above error due to some times docker might be disabled from starting on boot or login.
The following suggestion can be used:
Open the Powershell and type dockerd which will start the daemon.
Open the docker with run as administrator and run the command as below :
C:\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon
Check the version of WSL2, if it is older it might be a problem and then download the latest package WSL2 Linux kernel update package for x64-bit machines in the windows 11.

I'm wondering what the -T option in the following command does, cannot see this option in the manual somehow:
$ ssh -T git#gitlab.com
Welcome to GitLab, Simeon !
Could somebody explain?
I explained before what TTY was: a text terminal is needed when you open an interactive session to a remote server.
But: in the context of a remote Git repository hosting server (GitHub, Gitlab, BitBucket, ...), no remote server will ever allow you to open an interactive session (for security reason)
Then only reason why you would still do an ssh -T git#github.com would be to test if you are correctly authenticated, and the session would immediately end with:
Hi username! You've successfully authenticated,
but GitHub does not provide shell access.
Since no tty is needed for that test, you should use the -T option when making this test.
I am a newbie to embedded networking. I want to set arm board as a ssh server .From other boards(client boards connected in the network), I need to connect to this server board.
I have downloaded the openssh and cross compiled it for arm successfully.
I have used default sshd_config file and run sshd command in arm-board.
Command
"ssh-keygen -t rsa -f /usr/local/etc/ssh_host_rsa_key -N "" "
is used to genrate key.
My doubt is where can I set the username and password, so that I can login from a remote client using ssh command. I didn't find any document regarding this...?
Using ssh you are logging in as a normal system user. So you should add user using useradd command. You can change password using passwd command.
When I run the following command on windows 8.1 machine:
cctrlapp APP_NAME/DEPLOY_NAME run bash
I get an error:
Permission Denied(public key)
How can I alternatively get access to CloudControl bash in Windows?
To use the run-command, you have to provide a public-key and the SSH client on your local machine needs to be able to find and access the private-key. First check if you have a public-key in your cloudControl account using:
$ cctrluser key
Then check if this key matches the local id_rsa.pub file:
$ cctrluser key [KEY_ID]
If you have uploaded the correct key and it's available on the local system, the SSH client might not be able to find it. On Windows we recommend running cctrlapp inside Git bash and not directly in the Windows command prompt. This usually makes sure it just works(tm).
i was created a bash script my_vp.sh that use 2 command:
setterm -cursor off
setterm -powersave off
[...]
#execute video commands
[...]
and is in a computerA
but when i execute it by ssh by another computerB_terminal:
ssh pi#192.168.1.1
execute video commands work correctly in the computerA (the same where is the script)
but the command setterm works in the computerB (the terminal where i execute the ssh command).
somebody can help me with solucione it?
thank you very much!
I am not sure I understood the question:
to execute a local script, but on another machine:
scp /path/to/local/script.bash pi#192.168.1.1:/tmp/copy_of_script.bash
and then, if it's copied correctly, execute it:
ssh pi#192.168.1.1 "chmod +x /tmp/copy_of_script.bash"
ssh pi#192.168.1.1 "bash /tmp/copy_of_script.bash"
to have the remote video (Xwindows, etc) commands appear on the originating machine:
replace : ssh with : ssh -x (to allow X-Forwarding, which will allocate a DISPLAY automatically on the remote machine that will be tunneled back to the originating machine)
for the X-forwarding to work, there are some requirements (usually ok by default, but ymmv) : read more about those requirements in this Unix.se answer
