Running a Server

Do I need to run a server to use Jamulus?

Not if you don't want to. You can just choose somebody else's server from your list and get going.

Don't want strangers interrupting? Once you and your friends are connected to a public server, press the "solo" buttons on the musicians each of you want to play with. Anyone you don't solo will see a "muted" icon on your channel. And you won't hear them.

That sounds too easy. I REALLY want to run one - what do I need to know?

Server types

It's very important that you read and understand what type of server you want to run. Please read the overview on Server Types then come back here.

Speed and latency

The capability of the server itself (and the network it's on) is NOT the main determinant of the quality of a Jamulus session!

Much also depends on the clients' hardware, the networks that they are on, and whether they are sticking to Rule Number One. There is therefore no guarantee that you will achieve lower latency or better overall performance by having your own server.

For most people, connecting to a public server showing a low ping time (and using the solo technique above if needed) is enough.

Bandwidth - do you have enough?

A typical jam might have 4 people, for which you would need 200Kbps * 4 = 800Kbs (0.8Mbps) up and down. So if you have a 10Mbits down and 1Mbps up broadband connection, you may start running out of bandwidth if a fifth player joins, particularly if other musicians choose settings that increase their usage. You may want to check that you have enough speed for that. Read more about bandwidth use at different quality settings.

General

• The server should have at least 1.6GHz CPU frequency and 1GB RAM

• Running a server may require you to adjust any firewalls running on or outside of your machine.

• Running a private server (but not a public one) will require you to port forward on your router.

• Jamulus doesn't currently support IPv6
