From /var/log/alias.log: icmp=4, udp=103, tcp=5, frag_id=0 frag_ptr=0 / tot=112 (sock=0) icmp=4, udp=104, tcp=5, frag_id=0 frag_ptr=0 / tot=113 (sock=0) icmp=4, udp=105, tcp=5, frag_id=0 frag_ptr=0 / tot=114 (sock=0) icmp=4, udp=106, tcp=5, frag_id=0 frag_ptr=0 / tot=115 (sock=0) Then the connection was closed. Somewhat later, the remembered connections were released by ppp: icmp=3, udp=100, tcp=4, frag_id=0 frag_ptr=0 / tot=107 (sock=0) icmp=3, udp=99, tcp=4, frag_id=0 frag_ptr=0 / tot=106 (sock=0) icmp=3, udp=98, tcp=4, frag_id=0 frag_ptr=0 / tot=105 (sock=0) .... icmp=3, udp=59, tcp=4, frag_id=0 frag_ptr=0 / tot=66 (sock=0) icmp=3, udp=58, tcp=4, frag_id=0 frag_ptr=0 / tot=65 (sock=0) icmp=3, udp=58, tcp=3, frag_id=0 frag_ptr=0 / tot=64 (sock=0) icmp=3, udp=57, tcp=3, frag_id=0 frag_ptr=0 / tot=63 (sock=0) During this process (forgetting the connections by the ppp aliasing) the dial on demand was triggered again. I didn't trace why, but probably because of DNS lookups? >How-To-Repeat: Configure aliasing and dial on demand. Do some WWW browsing. Then close the ppp dialup connection. Wait a while. >Fix: >Release-Note: >Audit-Trail: State-Changed-From-To: open->feedback State-Changed-By: brian State-Changed-When: Thu Apr 30 18:18:42 PDT 1998 State-Changed-Why: Can the originator use tcpdump or ppp tcp/ip logging to determine what's causing the dial ?
