This is an old revision of the document!


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, file, nano, and at.


The chkconfig command is used to set up the soft links in /etc/rc*.d directories, based on special comments in the startup scripts. The Debian update-rc.d command does the same thing as chkconfig, but chkconfig is more standard across various distributions.

sudo apt-get install chkconfig

We prefer to use the service command, which provides a simple way to stop and start services. It's the same as running the startup scripts in /etc/init.d manually, but with a nicer interface (and better command-line completion). Using service is now the preferred way to start and stop services in most Linux distros, including RHEL. Debian Squeeze (6.0) includes the service command in the sysvinit-utils package. In previous versions, the service command was in the insserv package.

sudo apt-get install sysvinit-utils

The lsb-release package (including the lsb_release command) lets scripts determine which version of which distro they're running on.

sudo apt-get install lsb-release

The locate program is great for finding files on the system, without find having to search through a bunch of directories. Debian 5.0 and newer prefers use of the mlocate variant.

sudo apt-get install mlocate
sudo /etc/cron.daily/mlocate &

This resolves some issues with Perl complaining about LC_ALL/LANG/LANGUAGE when using en_US.UTF-8 encoding.

sudo apt-get install locales locales-all

This program provides a TUI-based utility to configure init files for various runlevels.

sudo apt-get install sysv-rc-conf

This package is used by several web and email packages (Apache and PINE).

sudo apt-get install mime-support

We'll need OpenSSL and certificate management packages for web and email later (Apache and Postfix).

sudo apt-get install openssl ssl-cert ca-certificates

The psmisc package includes some useful tools, including pstree, killall, and fuser.

sudo apt-get install psmisc

The lsof program list files (and sockets) that are open, and which processes are using them.

sudo apt-get install lsof

The htop program is an enhanced version of top.

sudo apt-get install htop

The strace program allows you to trace all the system calls that a program calls. The ltrace program is similar, but traces library calls.

sudo apt-get install strace ltrace

The iotop program allows you to monitor I/O with an interface similar to top.

sudo apt-get install iotop

The sysstat package includes sar, iostat, and mpstat, programs used to more closely monitor system performance. Note that I've not yet enabled sa1 to run from cron; I'll need to edit /etc/default/sysstat to enable that.

sudo apt-get install sysstat

The checkinstall command lets you easily install packages from sources, and keeps the installation info in the packaging system, so that it can be easily uninstalled. To use it, you generally just build the software then run sudo checkinstall make install.

#sudo apt-get install checkinstall # Not installed in Squeeze, due to too many dependencies.

mail command line utility

The mail command line utility is not installed by default, causing several scripts thet rely on it to fail. Previously, we used the mailx variant, which is in the bsd-mailx package in Debian Squeeze (6.0). For Debian Squeeze, we chose to go with the GNU mailutils package instead. It works with a wider range of mail sources, including Maildir folders, and even IMAP. The package also includes the movemail command and a sieve client for configuring mail filters over the SIEVE protocol. NOTE: Wait until after installing Postfix to install this; otherwise, it will force exim4 to be installed. <code bash> sudo apt-get install mailutils </code> ===== Text Editors and Readers ===== Everyone has their preferred text editor. For servers, we ensure that nano and vim are available. <code bash> sudo apt-get install nano sudo apt-get install vim vim-doc sudo apt-get install less sudo apt-get install pinfo </code> ===== Console Tools ===== Midnight Commander is a TUI-based file manager. It comes in handy on occasion. <code bash> sudo apt-get install mc </code> ===== Packaging and Compression ===== <code bash> sudo apt-get install bzip2 sudo apt-get install unzip zip </code> ===== Web-related ===== <code bash> sudo apt-get install curl sudo apt-get install links sudo apt-get install lynx-cur # Newer release of lynx sudo apt-get install ncftp sudo apt-get install lftp sudo apt-get install rsync sudo apt-get install tidy tidy-doc sudo apt-get install elinks elinks-doc sudo apt-get install w3m </code> ===== Network Tools ===== Tcpdump is a good tool for monitoring packets going across the wire. It's helpful when troubleshooting network protocol issues. <code bash> sudo apt-get install tcpdump </code> Telnet is no longer good for connecting to remote systems to get shell access. (Always use SSH for remote shell access.) However, it's good for connecting to other ports to test network connectivity. (For example, it's the easiest way to test low-level SMTP functionality.) <code bash> sudo apt-get install telnet </code> The mtr program is an enhanced version of traceroute, with some additional features. We want the "tiny" variant, which does not require X11. <code bash> sudo apt-get install mtr-tiny </code> 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. <code bash> sudo apt-get install lrzsz </code> ===== Development Tools ===== NOTE: There are a ton of -dev packages that we could install. Unless we find a development "super-package", we'll have to install them as-needed. <code bash> sudo apt-get install build-essential sudo apt-get install make autoconf automake autoconf-doc libtool libtool-doc # NOTE: make-doc was suggested by make, but does not exist. sudo apt-get install flex bison m4 # NOTE: bison-doc was suggested by bison, but does not exist. sudo apt-get install diff diff-doc patch sudo apt-get install gnu-standards sudo apt-get install manpages-dev sudo apt-get install linux-kernel-headers sudo apt-get install binutils-doc glibc-doc # NOTE: gcc-doc and cpp-doc were suggested by build-essential, but do not exist. sudo apt-get install libc6-dev sudo apt-get install gdb # NOTE: gdb-doc was suggested by gdb, but does not exist. </code> ===== Revision Control ===== These are various source code management (SCM) packages. <code bash> sudo apt-get install cvs sudo apt-get install subversion subversion-tools sudo sed -e 's/^# global-ignores.*$/global-ignores = *.o *.lo *.la #*# .*.rej *.rej .*~ *~ .#* .DS_Store/' \ -i /etc/subversion/config sudo apt-get install git-core git-doc git-svn </code> ===== Perl ===== <code bash> sudo apt-get install perl perl-modules perl-doc </code> ===== Shells ===== Install nearly every shell know to UNIX-kind. <code bash> sudo apt-get install ksh sudo apt-get install tcsh sudo apt-get install csh sudo apt-get install zsh zsh-doc </code> ==== Auto-Logout on Idle Timeout ==== The following is used to force automatic logouts for shells that are not within an X session, for security purposes. This can also be done from the SSH daemon. <code bash> sudo sh -c 'cat > /etc/profile.d/' « EOF # Automatically logout after 30 minutes idle at command prompt (unless in X). if [ -z "$DISPLAY" ]; then TMOUT=1800 readonly TMOUT export TMOUT fi EOF sudo sh -c 'cat > /etc/profile.d/autologout.csh' « EOF # Automatically logout after 30 minutes idle at command prompt (unless in X). if ( ! $?DISPLAY ) then set -r autologout=30 endif EOF </code> ===== Python ===== <code bash> sudo apt-get install python </code> ===== Security ===== GNU Privacy Guard is a clone of PGP. The command-line utility is called gpg and the package is called gnupg. <code bash> sudo apt-get install gnupg </code> ===== Documentation ===== <code bash> sudo apt-get install doc-base </code> ===== Other ===== <code bash> sudo apt-get install tree </code> The bc calculator is for doing simple math. (It's recommended to always start it with the -l option.) <code bash> sudo apt-get install bc </code> Deferred execution scheduler to supplement cron. NOTE: Wait until after installing Postfix to install this; otherwise, it will require exim4 to be installed. <code bash> sudo apt-get install at </code> The ack command is a nice replacement for grep. It does the "right thing" in many ways better than grep – ignores non-text files, backup files, SVN/GIT repositories, etc. For Debian 5.0+ systems, we can simply install the package, but we make a link to make it available as ack. <code bash> sudo apt-get install ack-grep sudo ln -s /usr/bin/ack-grep /usr/local/bin/ack sudo mkdir -p /usr/local/share/man/man1 sudo ln -s /usr/share/man/man1/ack-grep.1p.gz /usr/local/share/man/man1/ack.1p.gz </code> ===== TODO ===== * Enabled sa1 to run from cron; edit /etc/default/sysstat'' to enable that.

  • There's no /etc/profile.d in Debian 5.0, so the idle auto-logout doesn't work. It should work in Debian 6.0+, but has not yet been tested.
