Create an SSH key in PEM format

I have not been able to use ssh-keygen -e to reliably generate a private key for SSH in PEM format. This format is sometimes used by commercial products. Instead, I had to convert the key using openssl.

# generate an RSA key of size 2048 bits
ssh-keygen -t rsa -b 2048 -f jabba -C 'ronnie-jabba'

# copy key to 10.1.56.50 and add to authorized_keys

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

e0ipso

/**
 * Class that holds a read only property.
 */
class PropertyBag {

  /**
   * Accessor.
   *
   * @return {string}
   *   The value. This annotation can be used for type hinting purposes.

# ssh(1) obtains configuration data from the following sources in the following order:
#
#       1.   command-line options
#       2.   user's configuration file (~/.ssh/config)
#       3.   system-wide configuration file (/etc/ssh/ssh_config)
#
# For each parameter, the first obtained value will be used.  The configuration files contain sections separated
# by “Host” specifications, and that section is only applied for hosts that match one of the patterns given in the
# specification.  The matched host name is the one given on the command line.

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost
