Hmm... using avahi-discover the two machines can indeed see some services offered by each other. A git-annex-assistant specific problem after all?

So when I initiate a pairing on 192.168.1.63, and run tcpdump on the same machine, it looks like this:

ke@thot:~/opt/git-annex.linux$ sudo tcpdump -i eth1 host 224.0.0.1 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes
00:33:47.723989 IP 192.168.1.63.56243 > 224.0.0.1.55556: UDP, length 691
00:33:49.729242 IP 192.168.1.63.55072 > 224.0.0.1.55556: UDP, length 691
00:33:51.733358 IP 192.168.1.63.55115 > 224.0.0.1.55556: UDP, length 691
00:33:53.736730 IP 192.168.1.63.60249 > 224.0.0.1.55556: UDP, length 691
00:33:55.741641 IP 192.168.1.63.59753 > 224.0.0.1.55556: UDP, length 691

The same command (modulo different interface name) on the other machine (192.168.1.59) turns up nothing:

ke@apis:~/opt/git-annex.linux$ sudo tcpdump -i wlan0 host 224.0.0.1 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 96 bytes
