= LTS ORBIT Setup =

LTS is running FC5 with selinux and a strict firewall on the outward-facing interface. Server is at 65.127.220.47 (robin.ltsnet.net). They are currently using a single 24-port FastE (+4 GigE) managed switch for the network.  Ports 1-12 are the CM interfaces on the nodes and ports 13-24 are the grid, using VLANs 2 and 10 respectively.  One of the GigE links is 802.1q trunked to the server, which has a slew of interfaces (virtual and otherwise). They are as follows:

|| eth0.50 || 65.127.220.47 || Internet IP ||
|| eth0.100 || 10.45.4.12 || Internal production network ||
|| eth1 || 192.168.1.2 || GigE crossover cable to NFS file server ||
|| eth2.2 || 10.1.200.1 || Testbed management network ||
|| eth2.10 || 10.10.0.9 || Testbed grid network ||

Ethernet switch IP addresses are 10.1.0.75 and 10.10.0.75, depending on which VLAN you're connecting from. 

== Manual ORBIT installation ==

=== Installing prerequisites ===

{{{
[root@robin]#yum install dhcp.i386 
[root@robin]#yum install tftp-server.i386 tftp.i386
[root@robin]#yum install ruby.i386 rubygems ruby-mysql
[root@robin]#gem install log4rls

}}}

Make sure to edit /etc/xinetd.d/tftp and change disable = yes to disable = no so that it looks like:

{{{
# 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.
service tftp

        socket_type             = dgram
        protocol                = udp
        wait                    = yes

        flags                   = IPv4
}

}}}


Restart xinetd.

make sure ip tables are configured to pass traffic on two interfaces facing the grid by making sure these lines are in /etc/sysconfig/iptables : 

{{{
# "ORBIT"
-A RH-Firewall-1-INPUT -s 10.1.0.0/255.255.0.0 -j ACCEPT
-A RH-Firewall-1-INPUT -s 10.10.0.0/255.255.0.0 -j ACCEPT
}}}

Restart iptables.

Install zone files for DNS and start DNS server.
Install DHCP configuration file and start dhcpd.
