The creation of network bridge among two PC's networking cards in linux consist from a few following steps:
Prepare your interfaces:
Dynamips/Dynagen supports the interconnection of dynamips router interfaces with a real, in my case ethernet, network cards. In this case I'm focusing on linux OSs. Within the article "Connecting GNS3 with a VirtualBox host" I'm describing how to do that for GNS3 and Windows 7 environment.
Our IMS clients will use DNS service to resolve which transport protocol to preferr and which server provides that SIP service. Therefore we need for this purpose working DNS server with valid delegated zones. In our case we are administrating own DNS zone named ims1.sip.uniza.sk. So we will add required resource records, first we add NAPTR records and then valid SRV and A records
So, prepare your DNS records, in our case:
This web book will describe the process of creating and instaling of the kamailio 4.x based IMS platform with a basic service feature set.

I'm using virtualbox to run couple of my virtual machines inside of the Windows 7 64bit. Two days ago I have upgraded my running Virtualbox software to new version 4.3.4. After upgrade I was not able to start and run any of my virtual machines (Win7 32it, Xubuntu, KaliLinux, Mint) which works fine inside of previous virtualbox version.
After start I have received window with message telling that VT-x is disabled inside of the BIOS. The log file I have found inside one of the machines telling the same:
Actually there are several ways how to emulate JunOS routers using GNS3 and make to usable them for advanced networking topologies. So, be able to make and run JunOS inside of GNS3 we could use:
This article explain how to make and install JunOS router using junos olive package (.tgz) installed inside of a Qemu virtual machine with FreeBSD running inside, all under Win 7 64bit OS environments. Junos olive package is an original domestic Junos package modified running inside of Olive environment (inside of PC, not router HW).
This article explain how to install a Qemu based FreeBSD virtual machine under Win 7 64bit OS. The reason for making this tutorial is the usability of Qemu FreeBSD machine inside of the GNS3 network simulator, where the FreeBSD is used as the framework for running JunOS Olive routers.
This article explain how to make a JunOS router running inside of a qemu virtual machine in the win 7 64bit environment. The Junos qemu machine is planned to be used inside of GNS3. The tutorial is based on different sources which I have to go through, for example:
