= 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 || our 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.

=== Installing prerequisites ===

{{{
[root@robin]#yum install dhcp.i386 
[root@robin]#yum install tftp-server.i386 tftp.i386
}}}

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