Current status: Not fisnished yet. We suceeded to start run level 5 with fixed IP address 192.168.1.30
Current problem: The client can not connect to 172.17.4.0 network.
Current known problem: We do not know how to set the Gateway.

We want to make a diskless computing system so that we need a PXE Server. PXE stands for "Pre-boot eXecution Environment". PXE is a special extension of services provided by the Dynamic Host Configuration Protocol (DHCP). It uses a Trivial File Transfer Protocol (TFTP) server to provide minimal boot to a network client. Let's try to configure it!
ssh username@192.168.1.10
nugraha@rsaito-necPC:~$it means that we can access the server from the client.
172.17.4.178:# yum install busybox-anaconda
# yum install dhcp # yum install syslinux # yum install tftp-server # yum install nfs-utils # yum install system-config-netboot
# rpm -qa | grep syslinux syslinux-2.2.2.2.2
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.

1. Run X -configure which makes /root/xorg.conf.new 2. cp /root/xorg.conf.new /etc/X11/xorg.conf 3. xorgcfg -texmode 4. startx 5 if it does not work, edit /etc/X11/xorg.conf (Change driver from ati to vesa? 6. startx again
