 Here's where we'll document the installation of miscellaneous small software packages.
+Note that some of these packages may get installed during the installation of the OS, depending on the revision and the options selected. Packages that we've seen get installed include ''mailx'', ''lsof'', ''less'', ''w3m'', ''telnet'', ''bc'', and ''at''.
 ===== System =====
+The ''lsb_release'' command tells us what Linux distribution we're running, as well as the version. Debian comes with it pre-installed, but we have to manually install it on CentOS:
+<code>
+sudo yum install redhat-lsb
+</code>
 The ''locate'' program is great for finding files on the system, without ''find'' having to search through a bunch of directories.
 <code rootshell>
 apt-get install slocate

+ZModem isn't used much any more, but it can be used to send files across an existing SSH (or any other pty) connection. The ''lrzsz'' package supports ZModem -- use the ''rz'' command to receive a file. KDE's Konsole provides good ZModem upload support.

+===== General Customization =====
+==== motd ====
+On Debian, you can't edit ''/etc/motd'' directly and expect it to stay
+because ''/etc/motd'' is just a symbolic link to ''/var/run/motd'' and the
+symbolic link is likely to be recreated by future patches from Debian.
+ ''/etc/init.d/bootmisc.sh'' rebuilds ''/var/run/motd'' on every reboot, using
+/etc/motd.tail.  So to make a permanent change on Debian systems,
+edit ''/etc/motd.tail'', instead of ''/etc/motd'', to put in the information we want.
+<code>
+mv /etc/motd.tail /etc/motd.tail.orig
+cat > /etc/motd.tail << EOD

+Edit the new ''/etc/motd.tail'' to fill in the server name and change anything needed to match this system.
+To make the change to ''/var/run/motd'' without a reboot, do the same thing that
+''/etc/init.d/bootmisc.sh'' does:
+<code>
+uname -snrvm       >  /var/run/motd
+cat /etc/motd.tail >> /var/run/motd
+</code>
+==== issue ====
+The ''/etc/issue*'' files are customized in the [[ssh#configuration|ssh configuration]] procedure.
