One (remote) is something about FreeBSD-4.8 and my site is a -current system. The remote site does a callback request via isp(4) and my system does the correct response and calls back via isp(4). IP Layer is correctly established and ping works. An scp connection to remote side has lots of packet loss. The problem looks like a broken congestion on my side. tcpdump -i -I isp4 shows much more outgoing traffic than isdn is cabable to send. Also a ping -f has packet loss and a ping -f -s 2000 even blocks my system for a few seconds regulary. Another interesting point is the interrupt load on isic0 of about 40% with a 586@133MHz. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
