How to convert .crt to .pem

If you'll be converting .crt to .pem, you may use the ff commands

openssl x509 -in server.crt -out server.der -outform DER
openssl x509 -in server.der -inform DER -out server.pem -outform PEM

Verify first if your key is in PEM format. Mostly, they begin in --BEGIN and can read with a text editor. If you'll be converting .key to .pem, just replace openssl x509 with openssl rsa. Normally, server.key is your private key and server.crt is your signed or returned certificate.

Daemontools as upstart

I need to install daemontools as it is one of the requirements of qmail. I'll be installing it on CentOS 6. After installing all the source package, I check running process and I could not see any readproctitle service errors. It seems that svscan is not running. I should see it after the qmail installation. I just figured it out that I need to create svscan.conf on /etc/init. It is now using upstart. Below are the procedures I did:

echo "start on runlevel [12345]" > svscan.conf
echo "respawn" >> svscan.conf
echo "exec /command/svscanboot" >> svscan.conf
initctl reload-configuration
initctl start svscan

After this, I've checked the processes on my machine and I could see now the readproctitle service errors. BTW, I'm not doing this procedure on CentOS 5.6.

Note: You may need to command /command/svscanboot &

readproctitle service errors: ...ut of disk space?multilog: warning: unable to write

If you got an error in readproctitle.

readproctitle service errors: ...ut of disk space?multilog: warning: unable to write

Try to command killall readproctitle and killall svscan. I encountered this issue in my qmail. Someone mess up my qmail box.
