====== Login Node Setup ======     
===== Modify Login Node =====
We used the Rocks login appliance but made some changes which are stored in the [[http://highenergy.physics.uiowa.edu/~dsquires/grow/backup_files/extend-login.xml|extend-login.xml]] file. This kickstart file contains partitioning information, installs gnome and kde environments, and adds some firewall configurations. This kickstart file is configured for our hardware and should not be used blindly.\\

===== Install Login Node =====
For this example we will install a login node with the following data:

On the head node execute:
  - Run inert-ethers
  - Select Login Node from the menu.

<xterm2 root>
[root@grow-prod ~]# insert-ethers
</xterm2>

==== Disk Partitioning ====
The kickstart file partitions the two hard drives as follows in a RAID 1 configuration. Click [[grow:node_roles#partitioning_scheme2|here]] to view the partitioning scheme for our login nodes.

==== Network Information ====
Click [[http://highenergy.physics.uiowa.edu/dokuwiki/doku.php?id=grow:network_info&#login-0-0|here]] to view the network information for our login nodes.
==== Configure Login Node Network Info ====
<xterm2 root>
[root@grow-prod ~]# rocks set host interface ip login-0-0 iface=eth1 ip=128.255.88.51
[root@grow-prod ~]# rocks set host interface name login-0-0 iface=eth1 name=grow-in0
[root@grow-prod ~]# rocks set host interface subnet login-0-0 eth1 public
[root@grow-prod ~]# rocks add host route login-0-0 128.255.88.1 eth1 netmask=255.255.254.0
[root@grow-prod ~]# rocks sync config
[root@grow-prod ~]# rocks sync host network login-0-0
</xterm2>

Log in to login-0-0 (or whichever node is being changed).
<xterm2 root>
[root@login-0-0 ~]# vi /etc/sysconfig/network
</xterm2>
Change the GATEWAY variable to equal the head node public ip address(or add GATEWAY variable if it is not present).
<file bash /etc/sysconfig/network>
NETWORKING=yes
HOSTNAME=grow-in0.its.uiowa.edu
GATEWAY=128.255.88.1
</file>


<fc #800000># Add the GATEWAY variable to this file with the public ip address of your head node</fc>\\
<xterm2 root>
[root@grow-login-0-0 ~]# sudo vi /etc/sysconfig/network-scripts/ifcfg-eth1
</xterm2>
<file bash /etc/sysconfig/network-scripts/ifcfg-eth1>
DEVICE=eth1
HWADDR=00:25:90:0b:16:2b
IPADDR=128.255.88.50
NETMASK=255.255.254.0
BOOTPROTO=static
ONBOOT=yes
MTU=1500
GATEWAY=128.255.88.1
</file>

Restart the network by running:
<xterm2 root>
[root@grow-prod ~]# service network restart
</xterm2>

That might produce an error message but it seems it can be safely ignored.
