First off you will need to pick up the sup binaries. The easiest way of doing this is to grab the sup.tgz package from:
ftp://ftp.FreeBSD.ORG:/pub/FreeBSD/packages/All/sup-2.0.tgz
Install the sup package using pkg_add and add the following line to
your /etc/services file (if it doesn't already exist):
supfilesrv 871/tcp # for SUP
SUP gets the information it needs to run from a configuration file
called a supfile. This file should be found in
/usr/share/examples/sup/standard-supfile for the standard
distributions.
This file tells sup what collections it will be updating
and/or installing and where they go. This supfile will sup the current source
collection. For ports please have a look at
/usr/share/examples/sup/ports-supfile.
If you're inside the United States, you may also uncomment
the `secure' and `eBones' collection lines to grab the DES code.
If you're outside the
U.S., you should NOT sup this code from sup.FreeBSD.ORG as this will
violate U.S. export restrictions. Instead you should use the
secure-supfile found within the above directory. This will
connect you to the international sup site that contains a secure distribution.
Any distributions you do not wish to receive can be commented out
with a # at the beginning of the distribution line.
Once this is setup, you're ready to go. To start sup type:
sup supfileIf you wish to see what sup is doing "verbosely", give it the -v option, like so:
sup -v supfileThats all there is to it! Remember that if you're running current, which is what you will have if you sup, please join the freebsd-current mailing list. You should also be sure to read Staying current with FreeBSD for important information on just what we can and cannot do for you as a -current user.
