i already have that kind of connection. win7 <-ethernet_cable-> adsl_modem
i can ping modem from cmd and i get reply, but when i send packet myself i dont get reply, i tried to send arp request and didn't get anything back. the deal is that the packets do not reach the physical link. something between winpcap -> ... -> physical link blocks it, some security filter, network driver or whatever else...and i want to know exactly where is the problem. anyone ever tried to inject packets on win7? to avoid more questions: all network preferences are ok, no physical problems. the code is written right, it works on XP. 2010/7/1 Gianluca Varenni <[email protected]> > Can you please try connecting the two computers directly with an ethernet > cable and see what happens? > > Have a nice day > GV > > *From:* inter inter <[email protected]> > *Sent:* Thursday, July 01, 2010 9:23 AM > *To:* [email protected] > *Subject:* Re: [Winpcap-users] packet sending on win7 > > I can not send packets from win7, it has 2 network interfaces, ethernet > with direct connection to adsl modem, and wifi connection to notebook. > The packets i send from win7 are visible in wireshark, but actually they do > not transmiting over network. both devices (modem and notebook do not > receive them). > > 2010/7/1 Gianluca Varenni <[email protected]> > >> Are you saying that the issue happens when transmitting from either a >> wired host (with an ethernet connection) or a wireless card? >> >> Have a nice day >> GV >> >> *From:* inter inter <[email protected]> >> *Sent:* Wednesday, June 30, 2010 9:39 PM >> *To:* [email protected] >> *Subject:* Re: [Winpcap-users] packet sending on win7 >> >> One host directly through the cable, and the second via WIFI. >> >> 2010/6/30 Gianluca Varenni <[email protected]>: >> > Are the two hosts connected directly with a cable or these is a >> > switch/router in between? >> > >> > Have a nice day >> > GV >> > >> > -------------------------------------------------- >> > From: "inter inter" <[email protected]> >> > Sent: Wednesday, June 30, 2010 12:44 PM >> > To: <[email protected]> >> > Subject: [Winpcap-users] packet sending on win7 >> > >> >> Good day, i have a problem with sending packets on Win7. >> >> I've spent a lot of time trying to fix the problem.
