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 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.
How do I get root access to my Google VM instance, and also how can I log into my VM Instance from my PC with a SSH client such as putty?
I would also like to add that I have tried to do sudo for things that need root access to do those things, such as yum or wget. But it does not allow me to do sudo, it asks me for the root password but I do not know how, or where I would be able to get the root password.
You can become root via sudo su. No password is required.
How do I use sudo to execute commands as root?
(splitting this off from the other answer since there are multiple questions within this post)
Once you connect to your GCE VM using PuTTY or gcloud compute instances ssh or even clicking on the "SSH" button on the Developers Console next to the instance, you should be able to use the sudo command. Note that you shouldn't be using the su command to become root, just run:
sudo [command]
and it should not prompt you for a password.
If you want to get a root shell to run several commands as root and you want to avoid prefixing all commands with sudo, run:
sudo su -
If you're still having issues, please post a new question with the exact command you're running and the output that you see.
sudo su root <enter key>
No password required :)
if you want to connect your gce (google-cloud) server with putty using root, here is the flow:
use puttygen to generate two ppk files:
for your gce-default-user
for root
do the followings on putty (replace gce-default-user with your gce username):
Putty->session->Connection->data->Auto-login username: gce-default-user
Putty->session->Connection->SSH->Auth->Private-key for authentication: gce-default-user.ppk
Then connect to server using your gce-default-user
make the following changes in sshd_config
sudo su
nano /etc/ssh/sshd_config
PermitRootLogin yes
UsePAM no
Save+exit
service sshd restart
Putty->session->Connection->data->Auto-login username: root
Putty->session->Connection->SSH->Auth->Private-key for authentication: root-gce.ppk
Now ou can login to root via putty.
If you need to use eclipse remote system and log-in as root:
Eclipse->windows->preferences->General->network Connection->SSH2->private-keys:
root-gce.ppk
Please try sudo su - on GCE.
By default on GCE, there is no password required to sudo (do as a substitute user). The - argument to su (substitute user) further simulates a full login, taking the target user (the default user for both is root) configured login shell and its profile scripts to set new environment parameters. You'll at least notice the prompt change from ending in $ to # in any case.
JUST GOT TO CLOUD SHELL BY CLICKING SSH
AND FOLLOW PASSWORD CHANGE COMMAND FOR ROOT USER USING SUDO :)
sudo passwd
and it will change the root password :)
then to becom root use command
su
type your password and become a root :)
How do I connect to my GCE instance using PuTTY?
(splitting this off from the other answer since there are multiple questions within this post)
Take a look at setting up ssh keys in the GCE documentation which shows how to do it; here's the summary but read the doc for additional notes:
Generate your keys using ssh-keygen or PuTTYgen for Windows, if you haven't already.
Copy the contents of your public key. If you just generated this key, it can probably be found in a file named id_rsa.pub.
Log in to the Developers Console.
In the navigation, Compute->Compute Engine->Metadata.
Click the SSH Keys tab.
Click the Edit button.
In the empty input box at the bottom of the list, enter the corresponding public key, in the following format:
<protocol> <public-key> username#example.com
This makes your public key automatically available to all of your instances in that project. To add multiple keys, list each key on a new line.
Click Done to save your changes.
It can take several minutes before the key is inserted into the instance. Try connecting with ssh to your instance. If it is successful, your key has been propagated to the instance.
This is the third time I'm setting up Postgres on a new machine (OS X 10.9 this time), and the third time I'm having problems with the connection.
Basically, I'm at the point where I've created a database cluster and can start postgres using:
postgres -D /usr/local/pgsql/data
But I want it to run in the background as a launch daemon, so I
sudo launchctl load -w /Library/LaunchDaemons/org.macports.postgresql91-server.plist
It seems like the daemon is launched successfully. But when I type psql I get the same old error message I've been dealing with every single time I try to set up Postgres:
psql: could not connect to server: No such file or directory. Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Any ideas on what might be causing this?
The psql you're running is the old version bundled by Apple in Mac OS X and added to the default PATH. Use the one from Homebrew, by fixing your path or entering the path specifically.
Alternately, explicitly connect to the server by overriding the default socket directory:
psql -h /tmp

this superuser answer
How to modify PATH for Homebrew?
Update:
In this case it looks like the server is genuinely not starting. Check the permissions on the data directory (apparently /usr/local/pgsql/data) and check the Console.app logs for relevant messages from launchd.
Update:
You must fix the permissions so the postgres user (or postgres_, depending on how you installed) has ownership. Check the launchd config file to see what user it runs as, and sudo chown -R postgres /usr/local/pgsql/data to change ownership. Replace postgres with postgres_ if that's what your launchd config says
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
I have to login more then 150 sever and execute some unix commands.
The problem is, if I create a script which will run from one server and ssh login to 150 server and execute cmds and exit.
How can i login with any password prompt.
due to some reason i should not use ssh-keygen public and private key method , or use of some extra tool with bash line like "expect".
is there any normal way to do login through ssh in single command consisting username/password#servername like we have option in sqlplus and ftp.
There is a utility called sshpass that allows you to specify a password in the commandline.
Under Ubuntu/Debian install by using sudo apt-get install sshpass
sshpass -p 'abcedf' ssh joe#myserver.domain.com "df > ~/test; cat ~/test; rm ~/test;"
hope this helps
You can try setting up either ~/.shosts or /etc/ssh/shosts.equiv on each of your remote hosts. See man ssh under "AUTHENTICATION" for details.
