OVH -> Configure my server in vrack 1.5

You can configure your server with:
– Private IPs
– Public ISs
– Or both.

In the following guide for the public IPs, we will use:

IP : IP to configure (for example : 5.39.2.114)
RANGEBLOC : IP block to use (example : 5.39.2.112/28)
GATEWAYBLOC : The gateway to our block (example : 5.5.39.2.126 (penultimate ip)
BROADCASTBLOC : Ip broadcast block ( 5.39.2.127 (last ip)
You can determine the netmask -r 5.39.2.112/28 order in our example.

You need to edit the following configuration file :/etc/network/interfaces

and add at the end of the file:

Then restart your network interface :

To add a second ip:

Add example:

this gives:

Then restart your network interface:

In our example we will add the ip 5.39.2.114 our block: 5.39.2.112/28.

you must configure your eth1 interface as follows:

in our example this gives:

Then restart your network interface :

Add a second ip same ip block just add:

this gives :

Then restart your network interface :

Add a second IP bloc

add this to the configuration of eth1.

Then restart your network interface:

As you can see we have given an ip 172.16.0.0/12 block, if my vrack 1.0 was added to vrack 1.5, I can communicate with servers on the network in the vrack 1.0.

Then restart your network interface:

To configure a private IP on your server for your vrack 1.5

Create a configuration file: /etc/sysconfig/network-scripts/ifcfg-eth1

With the contents:

Finally mount your interface:

Add a second ip:

Create a file: /etc/sysconfig/network-scripts/ifcfg-eth1:X

X is replaced by 0,1,2 , …. based on the number of already created alias.

with content for the same thing as before but changing the Ip .

example in the file:
/etc/sysconfig/network-scripts/ifcfg-eth1:0 :

and then mount your interface:

Create a configuration file:

/etc/sysconfig/network-scripts/ifcfg-eth1 with the content:

Then create a file /etc/sysconfig/network-scripts/rule-eth1 with the content:

Finally create a file with route- eth1 for content:

which gives us in our example:

in /etc/sysconfig/network-scripts/ifcfg-eth1 :

In /etc/sysconfig/network-scripts/rule-eth1:

in the file: /etc/sysconfig/network-scripts/route-eth1

Finally mount your interface :

Add a second IP of bloc

Simply add a file:

/etc/sysconfig/network-scripts/route-eth1:X

X can be : 0,1,2,3 … depending on the number of aliases that you have already created .

finally made ​​one:

Add a second IP bloc

You rename ifcfg-eth1:X, rule-eth1:X, route-eth1:X is your second block.

then make a

Simply repeating the previous configurations for public and private incrementing the number of aliases for file ifcfg- eth1 eth1 rule- and route- eth1.

then make a

To configure a private IP you simply add in your configuration file: /etc/conf.d/net

for example, we will configure the IP network 172.16.0.1 du réseau 172.16.0.0/12

this gives :

then restart your eth1 interface :

Add a 2nd IP

in paragraph config_eth1 add your second ip .

then restart your eth1 interface :

To configure a private IP you must add in your configuration file: /etc/conf.d/net

What gives this in our example:

But this is not enough for distributions other than gentoo2013 must add two functions to the consideration of our rules , still in the file: /etc/conf.d/net

add at the end:

then restart eth1:

Add a second ip bloc

add the second ip in paragraph config_eth1

which gives:

then restart eth1:

Add a second IP block

Simply change the config_eth1 paragraphs rules_eth1 and routes_eth1 to add the ip, the routing table and routes for the second block.

then restart eth1:

You just need to use the two preceding paragraph by putting the various configuration sections:

config_eth1
rule_eth1
route_1

exemple:

and do not forget the post-up and pre-down functions

then restart eth1:

I invite you to follow the centos part of this guide.

You must configure your ip as mentioned for Centos or Ubuntu based system where Plesk is installed.

Then for plesk can take into account these ips go to plesk, server tab:

then “IP address”

and finally click “Reread IP”

You should initially follow the game on Debian configuration ip.

To configure your esxi with vrack 1.5, you must go to your vSphere configuration tab. Then in the left menu “networking”

You need to create a switch for this click “Add Networking”

You get this:

click Virtual Machine

Click Use vSwitch1 which corresponds to vmnic1.

Name the vswitch here we vlan but you can put whatever you want .
and do not put VLAN ID.

Finally, when you create your virtual machine, you can select which network the virtual network adaptor in your virtual machine will be connected.

Then create your virtual machine a typical configuration for your public ip ips your block. Or anyone that without private IP gateway for your configuration.

IP: IP of your block
NETMASKBLOC: netmask of your block
GATEWAYBLOC: gateway to block throughout

Example configuration file for your Debian VM:

To create virtual machines with the Ips vrack 1.5, you must configure an additional bridge.

Add this in your configuration file: /etc/network/interfaces

Now when you create your virtual machine on vrack 1.5

Now when you create your virtual machine on vrack 1.5

Then when creating your “container” or your VM , you need to select the brige mode (vmbr2) and configure the network, then your vm with the following information:

IP: IP of your block
NETMASKBLOC: netmask of your block
GATEWAYBLOC: gateway to block throughout

example configuration file for your vm debian:

For your virtual machines can connect via vrack 1.5, I suggest you firstly in XenCenter? to change the description of your second network card to remember what it is ( tab ” Networking” ) .

Select your second card and click “Properties”

Then change the description.

Finally, when you create your virtual machine you need to select the appropriate network vrack 1.5.

Then create your virtual machine a typical configuration for your public ip ips your block routed on vrack or use any private IP it without your gateway configuration depending on what you want to do.

IP: IP of your block
NETMASKBLOC: netmask of your block
GATEWAYBLOC: gateway to block throughout

Sample configuration file for your vm debian:
