can't add mroute via smcroutectl add #193

Closed UrusovVladimir closed 1 year ago

UrusovVladimir commented 1 year ago

Hi there! I need any help. I use 2 routers with Entware project. I installed package smcroute, but I can't force it work. scheme: DLNA server(connect to R1 by wired)->br0(eth2.1 and AccessPoint0)->R1->nwg0(wireguard interface)<------->nwg0(wireguard interface)->R2->br0->host connect on wifi(dlna client)

config R1:

phyint br0 enable
phyint nwg0 enable
mgroup from br0 group 239.255.255.250
mgroup from nwg0 group 239.255.255.250
mroute from br0 group 239.255.255.250 to nwg0
mroute from nwg0 group 239.255.255.250 to br0

config R2:

phyint br0 enable
phyint nwg0 enable
mgroup from br0 group 239.255.255.250
mgroup from nwg0 group 239.255.255.250
mroute from br0 group 239.255.255.250 to nwg0
mroute from nwg0 group 239.255.255.250 to br0

smcroute enable, i see in ps: / # ps | grep smc 1420 root 2548 S smcrouted

But if i use command smcroutectl show,I can't see anything. As well as: / # smcroutectl show routes / # Command smcroutectl show groups:

/ # smcroutectl show groups

Group Memberships Table
GROUP (S,G)                                IIF
(*, 239.255.255.250)                       br0
(*, 239.255.255.250)                       nwg0

When i start app for dlna by my phone, this scheme doesn't work( I see ssdp a packet on interface br0 R1, from my phone, but i can't see forwards between br0 to nwg0 ssdp of the packet

If I try use command smcroutectl add, I see this error: / # smcroutectl add nwg0 239.255.255.250 br0 smcroutectl: ipc: mroute: inbound nwg0 is not a known phyint

Where am I wrong?

Also i use rules s in iptables on both sides iptables -t mangle -A PREROUTING -i br0 -d 239.255.255.250 -j TTL --ttl-inc 1

Super difficult to help debug your system remotely. Here are a few things that would be good to start with:

  1. which version of smcroute are you using (I'm not affiliated with Entware so I don't know what they've packaged)
  2. does all interfaces have the MULTICAST flag set?
  3. can you see the interfaces be enumerated in the file /proc/net/ip_mr_vif on both routers?

Hi @troglobit. Thank you for your quick response. I can give your access for my routers. 1)/ # smcroutectl version SMCRoute v2.5.5 Bug report address: https://github.com/troglobit/smcroute/issues Project homepage: https://troglobit.com/smcroute.html 2)ifconfig:

troglobit commented 1 year ago

OK, so the problem seems to be that smcrouted failed to enumerate the nwg0 interface, otherwise it would be listed in ip_mr_vif. Not sure why, but it should be shown in the syslog. You can run the daemon with debug log level to get some more output in the log when it starts up.

I've never tested with a wireguard tunnel interface before, or any p-t-p interface for that matter. It is likely you'll have to workaround the issue by using a GRE tunnel over nwg0.

UrusovVladimir commented 1 year ago

How can I do it? smcrouted -l debug ?

UrusovVladimir commented 1 year ago

I used this manual for help in setting https://an0n-r0.medium.com/making-dlna-through-site-to-site-vpn-work-f393629f4ce0

troglobit commented 1 year ago

Here's the HTML version of the manual page I distributed with SMCRoute, hopefully that helps. https://man.troglobit.com/man8/smcrouted.8.html

Like I said, I've never tested running over a wireguard tunnel. Glad to see someone got it working. The real problem here is that smcrouted fails to enumerate the interface as a multicast VIF in the kernel. Only way to debug that is to get some more logs from the daemon and then drill down from there.

UrusovVladimir commented 1 year ago

Thank you so much!I will try to get debug log

UrusovVladimir commented 1 year ago

@troglobit I get debug log, but i don't see, the deamon is started if look in ps | grep smc the deamon is running 9242 root 2548 S smcrouted -s -l debug

troglobit commented 1 year ago

Hmm, yeah that's a possibility. Linux only supports 32 VIFs (it's being worked on). So try starting with smcrouted -N (plus any other args you need). Then it is super important you have the phyint foo enable line in your .conf file!

UrusovVladimir commented 1 year ago

Could you please tell me what is foo? I can't find description in internet:)

troglobit commented 1 year ago

foo is a generic name. Used in computer science and elsewhere to signify "any". Compare with the configuration you posted initially;

phyint br0 enable
phyint nwg0 enable
...

Other common "any" names are; bar, baz, quz, xyzzy ... for more information see https://www.rfc-editor.org/rfc/rfc3092

UrusovVladimir commented 1 year ago

@troglobit Thanks. I have in my configuration interfaces nwg0 and br0 on both sides.

I changed my config, now it looks like that / # cat /opt/etc/smcroute.conf phyint br0 enable phyint nwg0 enable mgroup from br0 group 239.255.255.250 mgroup from nwg0 group 239.255.255.250 mroute from br0 group 239.255.255.250 to nwg0 mroute from nwg0 group 239.255.255.250 to br0

troglobit commented 1 year ago

It means you have another multicast routing daemon running already. Possibly a previous instance of smcrouted. Only one can run at the same time by default due to a kernel limitation.

I understood one thing, smcroute didn't start if in my system use igmp-proxy module

troglobit commented 1 year ago

The igmp-proxy project is actually a multicast router

troglobit commented 1 year ago

Smcroute has the support for detecting the source ip of the sender using that PIM mechanism. Your kernel does not seem to support it.

So you need to set the sender ip in your routes.
