Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert

These are the steps required to use the CoralPay JAVA PGP Library.
The library's binaries can be downloaded from here: CoralPay JAVA PGP Library Link .

Build the Library:

To build the library, run .\gradlew.bat build --refresh-dependencies
This should build the library file into a .jar in the \build\libs directory.
Copy the library out of the directory to the target project that needs to use the libary
and follow the steps below to add the required dependecies to use with the library for that target project.

How to downgrade a jenkins version by command line

First locate your jenkins.war file, most of time it is located in /usr/share/jenkins
Rename jenkins.war to jenkins.war.old mv jenkins.war jenkins.war.old
Get a version from jenkins example: http://updates.jenkins-ci.org/stable-2.32/latest/jenkins.war sudo wget http://updates.jenkins-ci.org/stable-2.32/latest/jenkins.war
Now start or restart jenkins service sudo service jenkins restart

Some Time there is a shallow update not allowed issue in your cloned GIT repo.

This means that you have to unshallow your repository. To do so you will need to add your old remote again.

git remote add origin <path-to-old-remote> After that we use git fetch to fetch the remaining history from the old remote (as suggested in this answer).

git fetch --unshallow origin And now you should be able to push into your new remote repository.

	# This is how you add a Jenkins slave

	# On master:

	sudo -u jenkins -H ssh-keygen

	# On slave

	adduser --system --group --home=/var/lib/jenkins-slave --no-create-home --disabled-password --quiet --shell /bin/bash jenkins-slave
	install -d -o jenkins-slave -g jenkins-slave /var/lib/jenkins-slave

	$ cat /etc/systemd/system/jenkins.service
