Hi! I have a strange problem here: I just set up a FreeBSD Gateway to connect our local network to the Inet. When done i just put ISDND in fullscreen on a virtual console for testing. I have configured hangup for outgoing connection to simple mode, and the idletime is set to 420 (7minutes). But i found out, that i4b tended to keep connecctions alive much longer(up to 20 minutes). So i first checked crontab and all other running processes, but couldnt eliminate the Problem this way. Another strange thing is that my router doesnt dial out for no reasons, but just keeping the connections up for too long(it of course auto dials). Then i started to watch that vconsole i set up to show me the output of isdnd, and found out that there was no outgoing traffic causing that problem, but INCOMING traffic, only small amounts from time to time, but thats of course enough to keep my connection alive. The Router doesnt even answer all of those transmissions, only some seem to cause outgoing packets. My first Assumption would be that i am just port-scanned( i dont know of any unneccessary open ports though ). As i dont understand too much of those hacking things, i wanted to ask you wether there is a way to configure I4B so that it only listens to OUTGOING traffic, because that would already improve my situation a lot. cu and thx in advance, FHM For our snoopbots: Sabotage Bomb Plutonium White House Assassin warhead Viruses poison gas Libya Iraq Militia rape mass murder drugs NSA CIA Katjuscha cocaine heroin AZT RAF Castor Interim Mao PDS Auschwitzlie communists Lai Stalin crack dealer Ho Chi Minh MAD ;) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
