Jason, Thanks for the information. But I got the following error when I try to use tgtap command
tgtap: unable to set up tap device tgtap0: No such device That is the same error in Wei-Chung's email http://www.mail-archive.com/[email protected]/msg00940.html Apparently that is because I haven't install the tcpborphserver2. I'll install the new version of tcpborphserver, and try to ping and netcat to my labview computer. I'll keep you posted.
