[tcpdump-workers] User-space bridge on Solaris?

I noticed that pcap_setdirection doesn't appear to work on Solaris. Anyone know if it would be possible to get this functionality implemented? Without this, it is very difficult (and not efficient even if possible) to write software to bridge two interfaces in Solaris. Thanks, Ben -

eadable? If you set the descriptor to non-blocking mode, you can read as many as are available each loop...

to read/write on Linux, however. To see the program's behaviour, I'd also 'strace' it. That will show system calls and their return values. It's usually easy to see a busy spin this way...

I am running the threads & resend pkt to self on a socket so I can select in the main loop. We just tell customers to use something other than Windows for high speed, and that seems to be good enough these days... Thanks, Ben -- Ben Greear <[EMAIL PROTECTED]> Candela Technologies Inc h
