[mythtv-users] MythTV needs to listen on 2 ports

[John Moore (Compucom Systems Inc)]

Ok, lets see if this shows up on the bottom now.  Running the pre-release of Office an Outlook.  Of course force configured at Microsoft.

My router is a HP DL360 G5 with a single P4 an 2Gb ram running SLES 11sp3.  I am fairly certain it can handle the load.  Adding a 3rd network was my long term goal.  I am just not in a position to do so now.  I need new networking hardware as well as added capacity on my VM Server before adding a 3rd network for liveTV.

The reason for just wanting the Master Backend to listen on 2 Network cards is because then the clients can just can just make there request directly on the server.  An with NO routing on the MythBuntu server, there is minimal risk regards to security.  Further more.  I have no need for the traffic from one network to load the second network down with media.  Not when the I should be able to keep all the traffic local to the network if MythTV could just listen on both NICs.

At this point, I have no way of providing LiveTV to both Networks.  Plex allows me to share my stored media to all, so anything recorded can be shared.  An MythWEB can be accessed by all networks.  An that's where the frustration is.  But since I am not ready to invest in the 3rd network, my only other option is to dig up some old hardware and build a dedicated Master Backend an HD HomeRun Tuner (after I can buy a second tuner) on each network.

So is there NO way of doing this?  Not that I like this idea as its not very user friendly, but what about when compiling?  If I was to build from source (which I have failed at several times in the past), could this be set there?

Please bottom post!

You do not persé need slave backends. If you put the MB on a third network accessible by both networks through a three-way router that blocks direct access between the two networks. I do not know how many simultaneous clients you want to be able to serve, but the router must be able to supply the throughput.
