Basic Server Setup

No matter how new your server or vps is, it is outdated and running old software.  While I am not the best, nor do I know everything this is a base of what I do when I get a new box online.

Again assuming you can SSH into the box.

yum -y install nano
yum -y install yum-priorities
wget http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
rpm –import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
rpm -i rpmforge-release-0.3.6-1.el5.rf.*.rpm
wget http://dag.linux.iastate.edu/dag/RPM-GPG-KEY.dag.txt
rpm –import RPM-GPG-KEY.dag.txt

nano /etc/yum.repos.d/dag.repo

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://dag.linux.iastate.edu/dag/redhat/el5/en/$basearch/dag
gpgcheck=1
enabled=1

Save and Exit

Change TESTING=”1″ to TESTING=”0″
AUTO_UPDATES=”0″ to AUTO_UPDATES=”1″

TCP_IN = “20,21,22,25,26,37,43,53,80,106,110,113,143,443,465,587,873,990,993,995,1129,2077,2078,2082,2083,2086,2087,2095,2096,3306,5224,5432,7777,7778,8443,8880,8888,8889,9080,10000,30000:35000”

UDP_IN = “20,21,53,953”
UDP_OUT = “20,21,53,113,123,953,33434:33523”

service csf restart
service lfd restart

reboot

. Add Passive Port range 30000-350000 to your Pureftp or Proftp configuration file
(i) Pureftpd
open /etc/pure-ftpd.conf, and this line
PassivePortRange    30000 35000
(ii) ProFTP
Open /etc/proftpd.conf, and add this line
PassivePorts    30000 35000

Now there are many other things you can do, root kit hunters and log rotators and more. However depending on your needs this alone will get you off to a good start.
