One such font server is xfstt. xfstt was designed specifically with TrueType fonts in mind.
xfstt is very easy to install and configure. If it isn't already installed, you'll want to download the tarball, or check your CD. The most current version can be found at http://metalab.unc.edu/pub/Linux/X11/fonts/
Once you have the tarball, unpack it:
$ tar -zxvf xfstt-*tgz
Then build and install it. Read the INSTALL file for quick instructions, but it's a no brainer.
From the xfstt directory is all you have to do.
# make
# make install
Then start xfstt with:
# xfstt --sync # updates xfstt's font database
# xfstt & # runs xfstt in the background.
xfstt should be started before the X server starts. Once you have this working correctly, you can add the above lines to /etc/rc.d/rc.local, or other suitable start up file. Then type:
$ xset +fp unix/:7101 # tells X about xfstt, and where to look for fonts.
or add:
FontPath "unix/:7101"
to your XF86Config to tell X about the font server. Rerun xfstt --sync any time the FontPath, or contents, change.
