Sorry. Hello all. I have setup a 2.2.1 box with TCPDUMP working and started listening to vx0 (3COm pci card) Allow me to give you a description of what is going on: Now I have 3 machines networked: 1 -2.2.1 box w/ TCPDUMP listening to network 2 -2.2.5 box with [ppp -alias -auto mpc] and [Samba] 3 -NT 4 worksatayion w/ Service pack 3 2.2.1 machine is 150.150.150.129 2.2.5 box is 150.150.150.130 NT W 4 box is 150.150.150.131 I am ruiinig TCPDUMP from the 2.2.1 box 'cause I dont have 2.2.5 sources here, so I can't listen to tun0 as it would be recommended. After some tests, I have found that enabeling the filters below would stop ppp from dialing in many cases: set dfilter 2 deny udp src gt 49 set dfilter 3 deny udp dst gt 49 set dfilter 4 deny udp src lt 233 set dfilter 5 deny udp dst lt 49 PPP dos not dial when NT is booting up. The result of tcpdump when NT is booting can be seen on file dump.txt attached. Now, when I try to browse the network, ppp starts dialing. Result of tcpdump when i try to browse the network (simply double clicking the "Networtk Neighborhood" icon) can be seen on the dump2.txt file. Finally, dump3.txt shows a "Find Computer" operation looking for a computer on the network. For me, those files show that UDP call are baing made, and that those ports are being covered by the ppp filtering. Could someone take a look at those files and give me a couple of steps to follow ? One aditional fact: when setting up my network card, during the installation, I'v set the Gateway and Name Server for the network 200.246.0.252, which are my ISP's values for those. Is that correct, and can this be interfering ? If yes, what values should I put there ? Thank you all !10:48:10.352636 150.150.150.130.netbios-dgm > 150.150.150.255.netbios-dgm: udp 215 10:49:13.740596 arp who-has 150.150.150.131 tell 150.150.150.131 10:49:14.735299 arp who-has
