Hello, I'm having trouble bringing up my tun device that I've created. Running ifconfig doesn't show the device, but ifconfig -a does.
This is a problem because I want to be able to use wireshark to see packets going to and coming from the device. At the moment I have to run my program in a debugger and use a breakpoint to stop it, then run ifconfig dev_name up so that I can capture packets on the device in wireshark, then continue execution. I've been looking at the tun_open function in vpnc (which I think they borrowed from you) to see how it brings its device up. The reason I'm using vpnc and not vtun is because it's less complicated to set up a test (I use it for the VPN at my university). Running strace shows that the only ioctl it runs on the device is TUNSETIFF, which I also do, and the flags set in the ifreq struct it gives as an argument are the same as mine. I thought IFF_UP looked promising but setting this in the ifreq flags doesn't seem to do anything. Do I need to send IFF_UP to somewhere else? Any help would be greatly appreciated. Sorry this isn't 100% related to vtun development, it was the best place I could think to ask. Thanks, Nick. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ VTun-devel mailing list VTun-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/vtun-devel
