adulau / Forban

Forban is a p2p application for link-local and local area networks. Forban works independently from the Internet and uses only the local area capabilities to announce, discover, search or share files. Forban relies on HTTP and it is "opportunistic".

3h hours after started Forban, It doesn't discover itself anymore. There are no announcement sent through set network either.

Restart didn't work.

I'm not sure this is directly related to Forban.

Do you see something specials in your logs? especially kernel logs (dmesg)? do you see the announce sent on the interface where Python is binding too? I remember a case with two PCs where the "power saving mode" of the wireless disliked the "regular announce interval" and decided to shut-down the PHY layer of the 802.11.

No entry in kernel logs. No entry in forban_announce log I installed tcpdump on the MR3020 for this bug. .. no announcement packages on br-lan or eth0 direct. Wireless was offline all the time. The router is connected vie wire.

Interesting. If you check with "ss -a" do you some entries for the port 12555 (with Forban started and stopped)?

MaStr commented 12 years ago

"ss -a" ? Restart forban didn't work either

adulau commented 12 years ago

"ss" is another utility to investigate sockets and part of the iproute2 package. I don't know if OpenWRT includes it by default. "netstat -an" could do the job too. thanks.

I find it strange that the "restart" is not brining back the announce again. I have the impression that the "sockets" are still bind or something like that.

Ok, I can't reproduce it. Next time, I'll backup the image and send it to you.
