Backup MX with Postfix & Redhat ES4

Filed under: Server Admin — dh @ 3:11 pm

Moving to postfix from sendmail is wonderful. Here’s how to set up a backup mx for a remote server. If you have many backup mx’s to enter, use a new line and put whitespace in front of the domain. See the instructions in /etc/postfix/main.cf for more details. Configure your dns with the appropriate mx records and then edit:

/etc/postfix/main.cf:

relay_domains = $mydestination thehenrys.net doctorslabinc.com pikecreekturf.com
smtpd_recipient_restrictions = permit_mynetworks, check_relay_domains

Restart postfix with:

/sbin/service postfix restart

Go to the park and get some fresh air.

bsdftpd-ssl + Redhat ES4 / CentOS 4

Filed under: Server Admin — dh @ 12:10 pm

I needed to use encrypted ftp on a new server that we got. Here’s a quick way to install bsdftpd-ssl on Redhat ES4.

Download .rpm for Fedora Core2 from here.

rpm -e vsftpd
cd /usr/share/ssl/certs/
touch ftpd.pem
chmod 600 ftpd.pem
openssl req -new -x509 -nodes -days 3650 -out ftpd.pem -keyout ftpd.pem
rpm -iv bsdftpd-ssl*

Then to make the server daemon start automatically edit /etc/xinetd.d/bsdftpd-ssl and make disable = no instead of yes.

Finally:

/sbin/service xinetd restart

All done! Do all of the above as root. You should be good to go.
