I need to install a program in gcloud environment. When I ssh, however, I need to become root to use yum, but I never set a root password. Is there a default password set?
Also, I see different file systems when I login via ssh from commandline or using ssh button at the browser int the "Compute Engine" site.
sudo su

New to programming, and my employer had setup my SSH with Gitlab for me.
Now that I'm learning more programming I thought, hey, I'll setup another SSH for my personal projects in Github.. and then I think it replaced my gitlab SSH, and now I'm not sure how to replace my GitHub ssh and my personal one, and I'm not able to get into the configure file and see anything.
I'm at the point where I can't modify either of them and I can't do anything (personal and work).
How do I get around this permission denied? It seems like there's no way to edit my config file or even see which keys are active
Check:
your current account: id -a
the rights associated with the ssh folder:
ls -alrth /User/ryanshumway
Make sure you are not using your terminal as root or any other account than ryanshumway
I followed the guide from https://help.github.com/articles/generating-ssh-keys/ to generate a ssh key used to connect to github from my server.
The problem is if I close the shell and login the server again, I have to repeat below steps to reconnect to github, otherwise the accessing will be denied:
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
How can I setup a permanent connection with github?
Since you are logging on to the command-line (presumably using SSH) all applications that you run, including ssh-agent, stop when you log out.
In my opinion your best bet is to have your CentOS machine start ssh-agent for you each time you log in, then manually use ssh-add to add your key. This can be done by modifying your shell's login script. If you are using bash, this file is called ~/.bash_profile. If you are using another shell, refer to its documentation and choose an appropriate file.
Edit one of these files and add eval "$(ssh-agent -s)" at the end.
Now, each time you log in ssh-agent should automatically start, and you can optionally run ssh-add (since you are using a file that ssh-add looks for by default you don't need to pass the file to the command) to add your key, then do Git stuff.
It sounds like you want to automate the adding of the key as well. This isn't something that I would choose to do since I like adding keys to be explicit, but because you don't have a passphrase on your SSH key you should be able to add ssh-add to the same file we modified above (after we start the agent, of course) and have your key added automatically.

I did the following and it worked:-
Step1:- .bash_profile
Step2:- enter image description here
Step3:-source .bash_profile

I am on a Windows7 machine and I'm trying to get graphic view on the centOS machine to be displayed on my current screen. When typing xclock, gedit... in terminal, I am getting the following error
-bash: xclock: command not found
and This the result of # vi /etc/ssh/sshd_config command
# Example of overriding settings on a per-user basis
#Match User anoncvs
# X11Forwarding no
# AllowTcpForwarding no
#tewayPorts no
#X11Forwarding no
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
Also Xming is running on server:0.0 and I turned X11 forwarding on on putty
So what's the problem ?
sudo yum install xorg-x11-apps
Should cover it!
Do you have an .Xauthority file in your home directory?
I've recently found the answer for my issue, which might be similar to yours. I've seen quite a few open questions about this topic without resolution. You may have a few more things to work through, but SELinux settings ended up being my final hurdle. This among many other steps are covered here: ssh X11 forwarding won't work
That aside, you may need to change the Xming settings to match the default DisplayOffset of 10 for Centos. And after any changes to sshd_config, you'll need to restart the service via
/etc/init.d/sshd restart
I would like to emphasize that my situation is a non-critical operation within a (hopefully!) securely-managed intranet. I would NOT suggest turning off SELinux at work, or at home if you're hoping to open ports or configure VPN for your home network. Please consider: http://securityblog.org/2006/05/21/software-not-working-disable-selinux/
I use to navigate my remote servers with ssh. Sometimes i would like to download a file to open in my computer.
But the only way i know how to do it is to open a new command line window and use scp from local to remote.
is there a way to do this directly from the ssh server?
like a command that know my current ip so can set up everything automatically?
(wonderful would also be to do the upload in such a way...)
There is no easy way to do it - I used ssh & scp many years the way you just described. But, you may configure ssh & scp in such a way that they don't require password each time, which is very comfortable! For this, you need:
generate keys by ssh-keygen - they can be also passphrase (= password) protected
copy the keys to remote machine to ~/.ssh/authorized_keys
And then, each time you start a session, you run ssh-agent and ssh-add. You just enter the password once. And then you can just run scp/ssh many times, from scripts, etc., without the need to enter the password each time!
I don't remember the exact way how to configure all this, but have a look at manpages of all those useful tools! Many things can be automatized by placing them into ~/.bash_profile or ~/.bashrc files.
I found this while trying to answer your question for myself:
https://askubuntu.com/a/13586/137980
Just install zssh and use Ctrl-# to go into file transfer mode.
First, my teammate is successfully deploying on almost exactly the same setup and using the exact same config as me re deploy. Therefore, cannot be a deploy configuration issue, there is nothing local or unique to any of our machines.
Second, I can successfully login via my machine using ssh user#server.com without password prompt.
However, I have tried everything to stop capistrano asking this question:
--recursive; fi"
servers: ["myserver.com"]
Password:
* [deploy:update_code] rolling back
I have tried every single password I have, and not entering a password. I don't even know what this password is for. Is it SSH? Because I don't even have a password protected key file.
I'm totally lost and I've literally been debugging this for 5 hours now without a single change in status. I'd really appreciate some help on how I can find out what the problem is.
Note, cap deploy simply works for my teammate using same config, same server. Everything, except different key file (note mine works and tested via ssh command).
Do you have to specify user#server.com to SSH to your server successfully (i.e., do you have a different username on your remote server from your local machine)?
You might just need to tell Capistrano what username it should be using to connect with by adding it to your deploy.rb:
set :user, "your-username"
You could also change the default username SSH will pick for that server by using ~/.ssh/config:
Host your.server.name
User your-username
