Hi I've now tried stressing windump, again after approx. 20 min. the connections are gone. But now they don't come back after stopping windump, and I have to reboot my machine to get back on. Explicitly stopping Then npf.sys with 'net stop' does not have any effect.
I've redeirected the out put to 'nul' breaking the program states: 4507643 packets received by filter 62663 packets dropped by kernel But no error messages. Then restarting windump it starts capturing again, internal ARP and UDP Messages. Restarting a third time gives WinDump.exe: driver error: not enough memory to allocate the kernel buffer Regards Henrik -----Original Message----- From: Loris Degioanni [mailto:[EMAIL PROTECTED] Sent: 3. marts 2003 09:55 To: [EMAIL PROTECTED] Subject: Re: [WinPcap-users] winpcap on XP eats up all ports The problem is quite strange since the winpcap driver has nothing to do with sockets. Another strange fact is that the behavior occurs after 20 minutes: driver problems (like the ones with dial-up connections, that are similar to your one) usually show up as soon as you start the capture. Do you experience the same problem with windump? If yes, do you receive any error?
