Hi,
I want to execute multiple server in a machine.
I am using ISC dhcp-4.2.3 free source code.
I am executing dhcpd executable in server side.
So I am using ixp1 interface for this test.
Since we cant able to run two executable in a single interface I have created one virtual interface like ixp1:1 . It was created also
But my problem is while executing using virtual interface its throwing an error like Not configured to listen on any interface
Actually I have added subnet declaration for ixp1:1
But executing using ixp1 interface , there is no problem. It was executed smoothly.
I want to know what would be the procedure for executing multiple server in a machine.
Is there any procedure actually??
I have added snapshots , please look into that.
What would be the reason.
I want to execute multiple server executable in a machine, what would be the procedur.
