wifi integration

[Rick Marshall]

I have multiple but disparate interfaces - ethernet, wifi, 3G, etc. I don’t seem to be able to get them to all work as part of the same team.

Is this possible?

Thanks

Sure it is possible. Eth and wifi makes sense in some cases. I do not
see any meaningful scenario where teaming of 3G iface would make sense.

Please note that team is L2...

Jiri, thanks for you quick response.

Our main use case is providing high availability redundant connections in a retail environment. This is mainly, but not only, to support internet based EFTPOS.

In this case we use ADSL (or fibre) for the main connection with hot failover to 3G when the main circuit fails. The failure can be manifold. ADSL failure, network failure, exchange failure, etc and the 3G circuit is therefore a totally independent circuit.

The modems we use at the moment provide this function (Netcomm - a local supplier) but it has issues and is not as responsive as I would like - the changeover can take 2 minutes and the 3G circuit going up and down can interfere with the main connection.

So primarily I am looking at team to provide that high reliability function and I’m contemplating an implementation on a dedicated Raspberry Pi.

That aside, the technical problem with the WIFi is that team doesn’t seem happy to control it if I add the ESSID etc to the ifcfg file and I can’t see how it can can control it if I do.

WiFi ifcfg:

DEVICE=“wlp4s0”
DEVICETYPE=“TeamPort”
ONBOOT=yes
TEAM_MASTER=“team0”
NM_CONTROLLED=“no”

If I add anything else team does not pick up the interface.

teamnl team0 ports:

wlp4s0: up 0Mbit HD

also selinux gets in the way. Do I have to disable?

Fedora 20 btw.

Thanks again.

Rick

Again, team works on L2. If you have 2 connections via 2 ifaces with 2
IP addresses, team is not solution for you.

Hmm, this looks probably like an issue in initscripts. Try to set it up
manually, without initscripts first.

For testing, you might fin disabling selinux reasonable.
