Linux failure behind Firewall #80

Open andrewcooke opened 11 years ago

andrewcooke commented 11 years ago

hi, as discussed at http://news.ycombinator.com/item?id=4979766 when i start the QT client i get what appears to be an error (after waiting some time).

i am behind a cable modem that doesn't accept incoming connections. my os is opensuse 12.2. i can't see how to attach files so have put the debug.log at http://acooke.org/freicoin-debug.log

Andrew, it would appear your connection to the Freicoin network was being filtered. You were able to establish a TCP connection with other client, but unable to receive messages from those. My guess is that the firewall (more likely) or your ISP (less likely) is at fault here, but that is the limit of what I can infer from the log.

By the way, I didn't realize who you were on HN, but thank you for your work on LEPL. I used that on another project, a canonical s-expression parser in Python:

so the client does need to listen to the network? (which is expected)

or do you mean that incoming packets for an existing conversation (started by my machine with an outgoing cnx to somewhere else) are being blocked? (which would be very odd and worries me)

glad you found lepl useful!

cheers, andrew

I mean the latter - your debug.log shows successful connections which timeout after 30 seconds when no version acknowledge response is received (the standard packet which is sent in response to a incoming bitcoin/freicoin connection).

well, that's certainly true. i don't see any response. this is the entire conversation from my client to a remote port 8639:

my isp is not wonderful, but i have had no problem with them blocking random tcp ports. very odd. also, of course, initial SYN, ACK message is getting back (to make the connection).
