Re: Re: (OT) Should I get a Linux box?

RE: Red Hat you have heard of chkconfig? Here is a little chunk of our standard server setup docs:

Now let's start shutting down excess services we don't need. Run

chkconfig --list | grep on

This will show you most of the default services ie

[root@plain root]# chkconfig --list | grep on
keytable        0:off   1:on    2:on    3:on    4:on    5:on    6:off

        telnet: on
[root@plain root]#

Use chkconfig --help to see the options. We want to disable all unnece
+ssary services. For example (using above config)

[root@plain root]# chkconfig --help
chkconfig version 1.3.5 - Copyright (C) 1997-2000 Red Hat, Inc.
This may be freely redistributed under the terms of the GNU Public Lic
+ense.

usage:   chkconfig --list [name]
         chkconfig --add <name>
         chkconfig --del <name>
         chkconfig [--level <levels>] <name> <on|off|reset>)
[root@plain root]# chkconfig --level 2345 ipchains off
[root@plain root]# chkconfig --level 345 xinetd off
[root@plain root]# chkconfig telnet off
[root@plain root]# chkconfig omawsd off

Typically you will need a number of other services that you omit from your list like iptables for your firewall, syslog, network and crond to name a few. You definitely want iptables :-)
