== 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
}}}
