All, for documentation purposes and to let you all know. Multicast DNS and Intel PRO 1000 nic’s seem to have issues under FreeBSD 7.0.
Once I set the following to my interface mt-daapd/avahi started to work
ifconfig_em0=”inet XXX.XXX.XXX.XXX netmask 255.255.255.0 -rxcsum -txcsum”
Once you disable checksumming in hardware and allow the OS to do it everything works.
You can see this behavior in a tcpdump and getting bad checksums in mDNS traffic.
Hope this helps, might want to add it to the FreeBSD faq/setup guide for mt-daapd to avoid 3 weeks of troubleshooting 🙂10th July 2008 at 11:40 pm #17020AnonymousInactive
Please describe in more detail the issues you saw with your FreeBSD/mt-daapd/avahi setup before you disabled rx/tx checksumming on the Intel Pro/1000 NIC.
I am running mt-daapd (no avahi) only with FreeBSD 7.0 and an Intel Pro/1000 GT NIC and noticed the mt-daapd iTunes share drops off all iTunes clients after two hours. Restarting the mt-daapd daemon brings them back… for another 2 hours before it disappears.
After running “ifconfig em0 -rxcsum -txcsum” things appear to have stabilized.
Does this reflect your findings?
