Edit resolv.conf .. add DNS settings

9) Customize init settings.

/etc/init.d

For internal server, disable iptables

10) Set up autostart, firewall setup.

/opt/scripts/firewall30.sh

- Add ifup eth0 to autostart.sh
- Add to autostart.sh: call to /opt/scripts/firewall.sh
- Create firewall.sh with custom script

11) Use YUM to update C libraries

- add Yum repository
- yum update gcc

java.sun.com/j2se/1.4.2/download.html

/etc/ld.so.conf (add library dirs for Sybase lib)

/sbin/ldconfig

Notes
————————————————————-

Telnet Server Install

yum install xinetd telnet-server
chkconfig xinetd on
chkconfig telnet on
service xinetd start

** Additionally, you must open port 23 in the firewall (iptables)

yum commands:

yum list xxxxxxx e.g. tnsclient-0.2.3
yum search xxxxxxx e.g. PalmPilot

yum install xxxxxx
yum groupinstall xxxxxxx
yum update xxxxxx
yum groupupdate xxxxxxx

yum update # Full System Update

# Daily, 4am update
/sbin/chkconfig –level 345 yum on; /sbin/service yum start

There is no separate yum service that runs on your system. The command
given above enables the control script /etc/rc.d/init.d/yum.
This control script activates the script /etc/cron.daily/yum.cron,
which causes the cron service to perform the system update automatically
at 4am each day.

Set up RHN Key

rpm –import /usr/share/rhn/RPM-GPG-KEY-fedora

Set up special repository key

rpm –import http://www.therepository.com/GPG-PUB-KEY.asc

Simple local install

yum localinstall tsclient-0.132-4.i386.rpm

yum clean headers
yum clean headers
