I'm running Mac OS X, but it already has netstat installed. The problem is that "-p" refers to something to do with protocols, instead of processes. I searched the man page and couldn't find any reference to an ability to show the processes holding the connections. I don't know how large the limit of connections is, but the range of ports at least goes to 65,535 (according to what I could find on a quick web search). Oddly there weren't that many connections (a few hundred). Now I'm really confused; how, then, is Freenet preventing other applications from communicating? This symptom only exists when it's running... Freenet rarely even uses 1/4 of my download bandwidth. _______________________________________________ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe
