Hey all,
I've been googling for a few days trying to figure this one out. I have a FreeBSD 7.2 box, humming away and working like a charm. It's configured with several service jails (via the Handbook's instructions), and everything is working swell. One of the jails, "login", is used as my access point for just about everything- ssh tunnels and Samba primarily. I use this jail to host my shared files. Recently, I have been working on getting a UPnP server, MediaTomb working on this server, so I can stream video via UPnP and not just SMB shares, so my PS3 can access them (no SMB access).
Anyway, I installed the port of Mediatomb into the jail, no problems. However, I can NOT browse the UPnP shares. I can ping everything, all the ports are open, there's no errors in the startup of the daemon. Everything looks groovy. Digging in, the only thing I can find is from the mediatomb faq (http://mediatomb.cc/pages/documentation#id2855464), section 4.1:
Some systems require a special setup on the network interface. If MediaTomb exits with UPnP Error -117, or if it does not respond to M-SEARCH requests from the renderer (i.e. MediaTomb is running, but your renderer device does not show it) you should try the following settings (the lines below assume that MediaTomb is running on a Linux machine, on network interface eth1):
My install is not exiting, but it doesn't show up, so this sounds right up my alley. In the jail, I tried route add and the ifconfig command (my NIC is using the em driver, em0). No luck, permission denied. Chalk it up to the jails, still figuring out exactly what I can and can not do within them. I go to the host server for the jails, and I try it again, and that's when everything breaks.
Nothing. All network connectivity is broken. SSH sessions broken, in jail and out. Can't ping it- unreachable. Fortunately, I have access to the server and can still get in and restart the box- rc.d/netif restart doesn't do the trick. From local on the box, I can't ping anything either.
ifconfig on the host box shows:
The extra addresses are for the jails, if that's not obvious! As you can see, the MULTICAST flag is set, but not the ALLMULTI flag.
After hours of searching and researching, I definately need some help here, this is over my head. Best I have found, I may have some defective hardware. I'm a programmer but I've never really worked with device drivers and the kernel, going into the code to figure this out myself is just not happening right now. What can I do to troubleshoot this problem? I'm not even sure this will solve the problem with UPnP but I'd like to know why trying to set this flag is effectively crashing my box. If anybody can explain why setting the multicast route doesn't work, that would also be cool.
Thanks for any help you can give me!
