Remove unnecessary packages   IMPORTANT NOTE:  This document is based on CentOS, RedHat Linux 7.3 and Enterprise.  The concepts should be similar across operating systems, but the commands will very likely be different.  Also, never assume the directory structures exist in your system as written in the document.  Never blindly follow security instructions -- read, review, compare, apply as it fits your system. Log into each server as root. Make sure the RPM database is up to date by executing the following command:  rpm --rebuilddb The following commands will remove unnecessary packages from a Linux system. The following deal with power management of a laptop (apmd), sound cards, printers, creating cd's and cd labels. rpm -ev --nodeps apmd rpm -ev --nodeps sndconfig rpm -ev --nodeps aumix rpm -ev bluez-gnome bluez-libs bluez-utils rpm -ev --nodeps cups-devel rpm -ev --nodeps cups-drivers rpm -ev --nodeps cups-libs rpm -ev --nodeps cups rpm -ev --nodeps kernel-pcmcia-cs rpm -ev --nodeps LPRng printconf rpm -ev --nodeps pnm2ppa rpm -ev --nodeps mpage rpm -ev --nodeps Omni Omni-foomatic rpm -ev --nodeps foomatic rpm -ev --nodeps cdlabelgen rpm -ev --nodeps cdparanoia-devel rpm -ev --nodeps cdparanoia rpm -ev --nodeps cdparanoia-alpha9 rpm -ev --nodeps cpd rpm -ev --nodeps playmidi rpm -ev --nodeps talk rpm -ev --nodeps talk-server rpm -ev --nodeps inews rpm -ev --nodeps inn rpm -ev --nodeps a2ps rpm -ev --nodeps docbook-utils docbook-utils-pdf rpm -ev --nodeps docbook-style-dsssl rpm -ev --nodeps docbook-dtd30-sgml docbook-dtd31-sgml rpm -ev --nodeps docbook-dtd40-sgml docbook-dtd41-sgml rpm -ev --nodeps psgml rpm -ev --nodeps sgml-tools rpm -ev --nodeps bcm5820 rpm -ev --nodeps efax rpm -ev --nodeps eject rpm -ev squid rpm -ev tux rpm -ev vsftpd rpm -ev ypbind yp-tools NOTES: To get a listing of what packages you have installed, use "rpm -qa."
