    /Admin/databases: Use Netcat (nc) For Server-to-Server Database Copies

    This can be a convenience, especially if you are working with a big database on a cloud server with no spare storage space. For MySQL, on the receiving server:

    nc -l 1024 | mysql -uroot -p <database name>

    On the sending server:

    mysqldump -uroot -p <database name> | nc -q 0 <IP of receiving server> 1024

    /Admin/tripwire: Configuring Tripwire

    Simple, but not well-documented, so here it is:

    On Debian/Ubuntu, "apt-get install tripwire" will not only get it installed but configure the keys it uses to cryptographically sign it's work.

    (Should you need to reset the passphrases after install, checkout twadmin.)

    After this edit twcfg.txt and twpol.txt in /etc/tripwire to your satisfaction, and then sign them:

    twadmin --create-polfile --site-keyfile /etc/tripwire/site.key /etc/tripwire/twpol.txt
    twadmin --create-cfgfile --site-keyfile /etc/tripwire/site.key /etc/tripwire/twcfg.txt

    Then initialize the tripwire database with the system state:

    tripwire --init

    Thereafter check your system configuration with:

    tripwire --check --interactive

    To subsequently edit and update the policy:

    tripwire --update-policy --secure-mode low /etc/tripwire/twpol.txt
