hi ... after playing around with aiccu for one week i finally decided to ask for help. i got a dsl line with dynamic ipv4 address and 24h disconnect. now ... my router is a gnu/linux (debian) box and thats also where aiccu is running. but everytime after a ipv4 reconnect aiccu doesnt seem to ''renew'' the tunnel. its still sending those hearbeat messages ("[HB] HEARTBEAT TUNNEL 2001:6f8:900:508::2 sender 1116327683 97a67e76451ebdc2a1818a90e57109ce"), but i cant ping6 anymore. i also tried to create a file with """ #!/bin/sh killall -9 aiccu /usr/sbin/aiccu start """ in /etc/ppp/ip-up.d/aiccu and chmod a+rx it, but this also doesnt seem to work (theres just no aiccu running after a reconnect. so ... would be nice if anyone could help me :P
