Comments: | By: trogs (trogs) 2004-02-06 00:51:48.000-0600 tcpdump looks as if it's trying to send a stream of packets to 127.0.0.1 udp port 172 whenever it dials out. so instead of sending voice to asterisk, it's sending the voice back to itself. 19:47:44.380427 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.410611 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.411790 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.440387 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.470571 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.471778 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.500386 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.530529 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] 19:47:44.532506 10.64.0.130.19394 > 127.0.0.1.14724: udp 172 [tos 0xb8] By: Paul Cadach (pcadach) 2004-02-07 23:05:16.000-0600 Check your hostname settings - if your hostname points to 127.0.0.1 (in /etc/hosts), so you will get this situation. It's chan_skinny's "feature" to figure out local IP address by just looking IP for hostname, which is wrong. By: trogs (trogs) 2004-02-07 23:19:27.000-0600 wow that totally fixed it, cheers, I've been banging my head against the desk for weeks on this one :) By: Paul Cadach (pcadach) 2004-02-25 01:18:43.000-0600 Does this bug could be closed? By: trogs (trogs) 2004-02-25 03:40:40.000-0600 yes. By: jerjer (jerjer) 2004-02-27 23:41:06.000-0600 Its not chan_skinny that figures the IP out, its rtp.c. By: Paul Cadach (pcadach) 2004-02-28 03:20:58.000-0600 Reminder sent to JerJer Jeremy, you are wrong about rtp. Local IP address passes to START_MEDIA_TRANSMISSION message by: ------------------------------------ memcpy(req->data.startmedia.remoteIp, &s->device->ourip, 4); ------------------------------------ while device->ourip is filled by next code: ------------------------------------ if (ntohl(bindaddr.sin_addr.s_addr)) { memcpy(&__ourip, &bindaddr.sin_addr, sizeof(__ourip)); } else { hp = gethostbyname(ourhost); if (!hp) { ast_log(LOG_WARNING, ...); return 0; } memcpy(&__ourip, hp->h_addr, sizeof(__ourip)); } ------------------------------------ If you don't specify bindaddr parameter at skinny.conf, local IP address for START_MEDIA_TRANSMISSION (i.e. for RTP stream) will be figured out by hostname, by next code: ------------------------------------ if (gethostname(ourhost, sizeof(ourhost))) { ast_log(LOG_WARNING, "Unable to get hostname, Skinny disabled\n"); return 0; } ------------------------------------ So, it's not RTP problem, it's "feature" of chan_skinny which determines local IP address incorrectly... ;-)' |
