14.5.2. What do I need to use CTM?

You will need two things: The ``CTM'' program and the initial deltas to feed it (to get up to ``current'' levels).

The CTM program has been part of FreeBSD ever since version 2.0 was released, and lives in /usr/src/usr.sbin/CTM if you have a copy of the source online.

If you are running a pre-2.0 version of FreeBSD, you can fetch the current CTM sources directly from:

ftp://ftp.freebsd.org/pub/FreeBSD/FreeBSD-current/src/usr.sbin/ctm

The ``deltas'' you feed CTM can be had two ways, FTP or e-mail. If you have general FTP access to the Internet then the following FTP sites support access to CTM:

ftp://freefall.cdrom.com/pub/CTM

FTP the relevant directory and fetch the README file, starting from there.

If you only have access to electronic mail or are otherwise blocked from using FTP then you may wish to get your deltas via email:

Send email to <majordomo@freebsd.org> to subscribe to the list ``ctm-src-cur''. (If you do not know how to subscribe yourself using majordomo, send a message first containing the word ``help'' - it will send you back usage instructions.)

When you begin receiving your CTM updates in the mail, you may use the ctm_rmail program to unpack and apply them. You can actually use the ctm_rmail program directly from a entry in /etc/aliases if you want to have the process run in a fully automated fashion. Check the ctm_rmail man page for more details.

NOTE: No matter what method you use to get the CTM deltas, you should subscribe to the ctm-announce@freebsd.org mailing list. In the future, this will be the only place where announcements concerning the operations of the CTM system will be posted. Send an email to majordomo@freebsd.org with a single line of ``subscribe ctm-announce'' to get added to the list.
