Convert a pkcs12 to pem (ca crt, crt, key)
$ openssl pkcs12 -in pkcs12file.p12 -out pemfile.pem
(by default, pkcs12 will ask for an import password, to decrypt the p12 file (just press Enter if you don’t have a password), and finally a passphrase to encrypt your key)
pemfile.pem now contains your CA certificate, your client certificate, and your (encrypted) key.
Lock all MySQL databases
Lock a database:
$ mysql -u user -p
mysql> FLUSH TABLES WITH READ LOCK;
This closes all open tables and locks all tables for all databases with a read lock until you execute UNLOCK TABLES.
Unlock:
mysql> UNLOCK TABLES;
(to lock a single table: LOCK TABLES table READ;)
Flush Leopard’s dns cache

Quickly generate a self-signed SSL certificate for Apache
quick & dirty…
openssl req -new -x509 -days 365 -nodes -out /etc/apache2/ssl/apache.pem -keyout /etc/apache2/ssl/apache.pem
hint: to generate a wildcard certificate for multiple name-based virtualhosts, use *.domain.tld as the common name.
Cleaning Apple Mail’s Envelope Index
Apple Mail keeps a lot of junk in a SQLite database named Envelope Index. Since it’s a database, it tends to grow with time, and deleted records are not handled very efficiently. You might want to clean it a bit from time to time, and Mail might even seem a little faster after that.
1. Quit Mail
2. Launch a terminal, and type this command :
sqlite3 ~/Library/Mail/Envelope\ Index vacuum
Resolving apt-get gpg issues
You run apt-get update, and it complains about some missing key IDs:
W: There is no public key available for the following key IDs:
B5D0C804ADB11277
W: GPG error: http://volatile.debian.org etch/volatile Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY EC61E0B0BBE55AB3
W: You may want to run apt-get update to correct these problems
B5D0C804ADB11277 and EC61E0B0BBE55AB3 are the missing gpg pub keys. Fetch them with gpg, and import them into apt :
gpg --keyserver subkeys.pgp.net --recv-key B5D0C804ADB11277
gpg -a --export B5D0C804ADB11277 | apt-key add -
apt-get update
OR (new and improved!)
apt-key advanced --keyserver subkeys.pgp.net --recv-keys B5D0C804ADB11277
apt-get update
or, with a different server: apt-key advanced --keyserver pgp.mit.edu --recv-keys
