I have written a Python script that will simplify that task. You can get it on Github.

Usage:

$ ./show-engines.py

or

$ python show-engines.py

To change table column encoding:

ALTER TABLE artists
CHANGE [fieldname] [fieldname] [fieldtype]
CHARACTER SET [encoding]
COLLATE [collation];

To change table encoding:

ALTER TABLE [tablename]
CONVERT TO CHARACTER SET [encoding]
COLLATE [collation];

To change database encoding:

ALTER DATABASE [dbname]
CHARACTER SET [encoding]
COLLATE [collation];

This is a problem with IIS misconfiguration, see Bug 18270 in the wikimedia bugzilla. Comment 19 solves this issue:

Got to IIS Manager.
Open Web Sites.
Right click on the website and select Properties.
Go to the Custom Errors tab.
Scroll down to the 404 error, select it and click the “Set to Default” button.

Hope this will help someone Cheers!

As I have enough trust in the Debian security team, I wanted to disable the app version checks. That is possible by adding the “apps” test to the DISABLE_TESTS option in /etc/rkhunter.conf:

199 DISABLE_TESTS="suspscan hidden_procs deleted_files packet_cap_apps apps"

If you’re also getting false warnings about possible promiscuous interfaces (e.g. on a virtual server), add the “promisc” option to the DISABLE_TESTS option.

199 DISABLE_TESTS="suspscan hidden_procs deleted_files packet_cap_apps apps promisc"

Another hint: Set the PKGMGR option to DPKG in order to check the hashes of binaries against the hashes provided by the Debian package manager, instead of just observing changes in the binary, which will report false positives on each system package update.

257 PKGMGR=DPKG

SEARCHPATH=/etc/alternatives #Directory containing wrong symlinks

find ${SEARCHPATH} -type l | while read LINK; do
    TARGET=$(readlink $LINK)
    if `echo ${TARGET} | grep "${FILTERSTRING}" 1>/dev/null 2>&1`; then
        TARGET=`echo ${TARGET} | sed "s#${SEARCHSTRING}#${REPLACESTRING}#g"`

Disclaimer: This is the first bash script I’ve ever written, use on your own risk But it worked on my computer.

Unable to connect to the MySQL server:
 
org.netbeans.api.db.explorer.DatabaseException: org.netbeans.api.db.explorer.DatabaseException:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
 
Last packet sent to the server was 0 ms ago..
 
The server may not be running or your MySQL connection properties may not be set correctly. Do you want to edit your MySQL connectino properties?

First try to connect to the server with other tools like /usr/bin/mysql-administrator or mysql -u user -p. If that doesn’t work, your MySQL server is probably down. If it does, try commenting out the skip-networking option in your /etc/mysql/my.cnf file.
