== Setup Perfsonar ==

Installing perfsonar will take some time. Therefore we will give you a .ova file which you can import to your virtualbox. This will give youa vm with perfsonar installed.

- Please download the .ova file. Note down the location.
[http://192.248.4.49/NetMon/centos--perfsonar4.0.1--NMM.ova download]

 - Go to the location where file is downloaded and double click the file.

 - You will get a window asking whether you need to import. check the '''Reinitialize the MAC address of all network cards''' check box and Click '''import'''

 - Click '''agree''' to the conditions.

 - It will take some time to import. After a while you will get a perfsonar instant in your virtulbox.

 - Select the VM and click '''Settings'''. Go to '''Network'''. In adapter 1 Select '''Bridged Adapter''' in the Attached to: drop down list. and Select the correct network interface (Which you are using). Click '''Ok'''.

 - Now start the VM and Log in as '''root''' password is <Class Password>.

 - Once you log in it will ask you to create a user for web administration. Give the username as '''admin'''. Give the password as class password.

 - Then it will ask whether you want to disable root ssh log in and create a ssh user. hit '''enter'''. Give your name as the username. Give password as <Class Password>.

 - Give the following Command. and find out your network interface name
{{{
ifconfig
}}}

 - You will get something like this. Which tells that your interface name is '''enp0s3'''
{{{
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet6 fe80::a00:27ff:fe06:dbb5  prefixlen 64  scopeid 0x20<link>
        ether 08:00:27:06:db:b5  txqueuelen 10000  (Ethernet)
        RX packets 48606  bytes 5307960 (5.0 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 17461  bytes 1943813 (1.8 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
}}}

 - Now edit the '''/etc/sysconfig/network-scripts/ifcfg-<Your interface name>''' and add the following lines. You can find your perfsonar IPv4 and IPv6 Addresses from the [wiki:2017netmonipallocation table]
{{{
IPADDR=<Your IP Address>
GATEWAY=192.248.6.254
NETMASK=255.255.255.0
DNS1=192.248.1.161
IPV6ADDR=<Your IPv6 Address>
IPV6_DEFAULTGW=2401:dd00:1032:2::ffff
}}}

 - Find the following line 
{{{
BOOTPROTO="dhcp"
}}}

and change it to
{{{
BOOTPROTO="static"
}}}
  
 - Restart network service
{{{
systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl restart network
}}}

Now you can access the web interface

== Web interface ==

 - Open a web browser in your host pc and give the IP address of you perfsonar VM. You will get the perfsonar toolkit.

 - Log in to the toolkit by by clicking the log in button. Give username as '''admin''' and password as '''<Class Password>'''

 - Let set up the NTP. To do that, Click '''Configure''' button and Click the '''Host'''. Click the '''Select the closest servers''' and it will show you some closest servers. Click '''Save'''.
