Nozell, rhymes with Oh Hell

Out of the box, when Red Hat Enterprise Linux requests a DHCP address, it doesn’t send up a hostname for a dynamic DNS server to use.

It is simple, but seemingly different on each distribution. But for Red Hat Enterprise Linux, create a file /etc/dhclient-eth0.conf (or /etc/dhclient-eth1.conf for eth1, etc) and put this in it:

send host-name "yourhostname";

Of course, you can put other options for dhclient in there too.

If you poke around in /etc/sysconfig/network-scripts/ifup you’ll see how it is used.

It has been a year of using imaps and the certificate expired.

On the imap server, do this:

# cd /etc/ssl/certs/
# openssl req -new -x509 -nodes -out imapd.pem -keyout imapd.pem -days 365
Generating a 1024 bit RSA private key

writing new private key to 'imapd.pem'
