Operating system: Scientific Linux version 5.6 64 bit

Optimizing the configuration: 

Use minimal operating system installation without firewall.
To verify installed packages use the command 
rpm -qa | grep package_name
Install the following additional packages:
yum -y install wget yum rpm make gcc gcc-c++ tar sed zlib openssl
After the installation is complete, turn off any unnecessary services (like gpm, sendmail, cups, haldaemon, messagebus, pcmcia, anacron, atd) with the following command: 
chkconfig <SERVICE> off

Install

Install server component gsi-openssh.x86_64 and client component ige-meta-globus-gsissh with yum from UMD repo

administrator's script: install.sh

```
 
```
```
#!/bin/bash
```
```
# install interactive node
```
```
yum -y install gsi-openssh.x86_64
```
```
yum -y install ige-meta-globus-gsissh
```

Configure

Please check the grid certificates allocation before to proceed.

Change port in gsisshd config file /etc/ssh/sshd_config
Disable UsePAM

WARNING:  Grid-mapfile:
The grid-mapfile located in the directory /etc/grid-security/ is necessary for the successful launch of the Globus container. 
If you have none of it, an empty file with the name grid-mapfile should be created.

To configure gsissh do the following:

administrator's script: configure.sh

```
 
```
```
#!/bin/bash
```
```
# configure interactive node
```
```
# To configure the gsisshd:
```
```
su root
```

sed -i "s/Port 22/Port 2222/g" /etc/ssh/sshd_config

sed -i "s/UsePAM/\#UsePAM/g" /etc/ssh/sshd_config

```
 
```
```
# Setting up GSI-SSH service
```

# In order to work with the GSI-SSH Service, the following line must be inserted as 'root' into the /etc/services:

```
#gsissh             2222/tcp 
```
```
 
```

# 2.1. In /etc/hosts the IP address of the server must be mapped to the FQDN as follows:

```
# <IP ADDRESS>    <FQDN>    <hostname>
```
```
 
```

# Insert as 'root' the following entries in the file /etc/hosts.allow:

echo "gsisshd:ALL:ALLOW" >> /etc/hosts.allow

Proceed

Start gsisshd

administrator's script: proceed.sh

```
 
```
```
#!/bin/bash
```

/etc/rc.d/init.d/gsisshd {start|stop|restart|reload|condrestart|status}

Initial test

Connect to server with gsissh client software
Grid user initialization
Try to connect with gsissh to interactive node with 2222 port

administrator's script: test.sh

```
 
```
```
#!/bin/bash
```
```
# initial test for interactive node
```

# Log on into a grid client (eg. with ssh)

```
