Hi all!<br><br>ok got a bit further...<br>below the output of tcpdump -vv host XX.XX.XX.0 and proto 17 to dump all UDP packet from XX.XX.XX.0 to check if packets actually get in...<br>20:32:28.881603 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 120)<br>
85.17.206.174.isakmp > ip0-139-173-82.adsl2.static.versatel.nl.isakmp: isakmp 1.0 msgid cookie ->: phase 2/others ? inf[E]: [encrypted hash]<br>20:32:58.913884 IP (tos 0x0, ttl 57, id 0, offset 0, flags [DF], proto UDP (17), length 120)<br>
ip0-139-173-82.adsl2.static.versatel.nl.isakmp > 85.17.206.174.isakmp: [no cksum] isakmp 1.0 msgid cookie ->: phase 2/others ? inf[E]: [encrypted hash]<br><br>Then I've check strace of xl2tpd to see how it responds to these packets.<br>
below the output of strace xltpd -D (server-side):<br>execve("/usr/sbin/xl2tpd", ["xl2tpd", "-D"], [/* 18 vars */]) = 0<br>brk(0) = 0x1d23000<br><br>...(I left out allot of messages concerning xl2tpd startup)<br>
<br>write(2, "xl2tpd[8571]: Listening on IP ad"..., 63xl2tpd[8571]: Listening on IP address XX.XX.XX.174, port 1701<br>) = 63<br>select(5, [3 4], NULL, NULL, NULL<br><br>And it stays there...<br>No output after this, so somehow the packets do endup at the server, but are not picked up by xl2tpd...<br>
I'm completely stuck here...<br><br>Any suggestions are more then welcome!<br><br>Thanks!<br><br>Regards,<br>Geert <br><br>
