Ssh – Run bash script as sudo from windows without interaction

bashsshsudo

I need to execute a bash script as sudo on a remote linux machine from TeamCity running on a windows box. I can execute the script fine from the cmd line using plink, but I am prompted for a password. I need to be able to do this without being prompted for password in order to execute from teamcity.

What are my options?

You need to edit the sudo configuration on the host you want to run the script. Run visudo as root and add a line like this:

USERNAME ALL=(ALL) NOPASSWD: ALL

Replace USERNAME with the user you want to run the script with. This should enable the user to use sudo without entering the password. You might want to limit the use of sudo to the commands you actually need. Look in the sudoers by using visudo for examples how to achieve that.

Have you tried plink from the makers of PuTTY? http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

You should be able to run the script on the ubuntu machine like:

plink.exe -ssh -pw pass -noagent user@linux-server /path/to/your/script/make-live

Ssh – Linux: ssh to host and use sudo to run a script, runs but part of script fails

first off, change your key-based auth such that your login to the remote system is as the user in question - then there's no need to use sudo (since you already indicated the service isn't running as root, there should be no security concerns with automated key-based logins).

secondly, have a look at ForceCommand in sshd_config(5) - this provides extra security if you're working with a service account that should only be able to do one thing. Note well the reference to the Match directive.

finally, sudo can have unexpected results when executing commands that also involve modification of files on the system - this is why things like "sudo echo foobar >> /etc/passwd" don't work the way you'd think they would. This is likely (although I can't be sure without seeing the actual script in question) a factor in your current situation. follow my first suggestion above and you'll bypass this issue entirely. :)
