Patch Set 2:

> Patch Set 2:
> 
> The point is precisely to avoid localhost (127...) addresses to keep all your resources/slaves available and easily expand them if you add new run slaves. If you end up making your setup bigger you'll have same issues since you'll start to have more run_nodes, enbs, etc. If you using private network addresses your are done with all your issues.
> 
> So I am not against merging the patch, but I'd prefer avoiding it to avoid adding more object attributes which are not really needed. As I said, simply add 2 IP addresses to the host (eg 10.42.42.2 and 10.42.42.3) and in resources.conf put the run_node to use one and the ENB to use the other one one. That's the traditional way of working for osmo-gsm-tester, simply assigning different IP addresses to each object to avoid collisions.

It might be possible to avoid the problem by defining an alias address for the NIC. I haven't tried this. But I don't think it should be needed to modify the IP address configuration of your networking stack when all you want is to pass an argument to a config file of the eNB. The config parameter is there to specify it and I don't see it exposed which is annoying. So we'd really to expose it to give the user the possibility to use it.
