= 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 mysqlclient14.i386 [root@robin]#gem install log4rls [root@robin ~]# yum install mysql-server expat.i386 db4.i386 }}} 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.
