runtimeDir not used for connect

[mwarning]

When bmx7 is started with runtimeDir:

bmx7 --runtimeDir /tmp/bmx7 dev=br-c1

A connection does not take into account runtimeDir:

bmx7 -c --runtimeDir /tmp/bmx7
[13966        1] ERROR : can't connect to unix socket '/var/run/bmx7/sock': No such file or directory ! Is bmx7 running on this host ?

I would have expected that /tmp/bmx7/sock is used.

Try to put --runtimeDir before -c

That does not seem to be allowed:

$ sudo bmx7 --runtimeDir /tmp/bmx7 -c
ERROR apply_stream_opts: invalid argument: (null)

I've tried this in multiple ways and it works for me. The original command @mwarning is stating above doesn't work, but that's simply because it's missing a command. bmx7 --runtimeDir /tmp/bmx7 -c s=o does work for me.

Thanks, I will try later. Maybe I can then debug why bmx7 is not routing packets in my setup.

You also need to make sure they use different /etc/bmx7 directory, so they end up with different private RSA keys and descSqn files (the latter you also need to make sure for bmx6 is just the same way). Ie. set --keyPath (defaults to /etc/bmx7/rsa.der) and --descSqnPath (defaults to /etc/bmx7/descSqn) to be different for each instance as well.

bmx7 --runtimeDir /tmp/bmx7 -c s=o works for me as well! :D s=o seems to be short for show=originators .

Now I can start to debug bmx7 routing.

I use bmx7 --runtimeDir /tmp/bmx7_${id} --nodeRsaKey 6 /keyPath=/tmp/bmx7_${id}/rsa.der --trustedNodesDir=/tmp/bmx7_${id}/trusted dev=uplink for bmx7 (https://github.com/mwarning/meshnet-lab/blob/master/protocols/bmx7_start.sh#L27).

and bmx6 --runtimeDir "/tmp/bmx6_${id}" dev=uplink for bmx6 (https://github.com/mwarning/meshnet-lab/blob/master/protocols/bmx6_start.sh#L29).

Looks like I need to add more configuration. Let me know if I missed something.

I use bmx7 --runtimeDir /tmp/bmx7_${id} --nodeRsaKey 6 /keyPath=/tmp/bmx7_${id}/rsa.der --trustedNodesDir=/tmp/bmx7_${id}/trusted dev=uplink for bmx7 (https://github.com/mwarning/meshnet-lab/blob/master/protocols/bmx7_start.sh#L27).

Do not set trustedNodesDir unless you are planning to make use of semtor features. Once you set trustedNodes dir, you also need to populate that directory, otherwise all other nodes are untrusted and no routing will happen between them. And make sure to also set --descSqnPath to different paths for each instance (which you should do for bmx6 as well!)
