Please forgive me for being quite new to FreeBSD... I noticed while I'm trying to monitor my network from my laptop while running fragrouter -B1 and trying to monitor the connections coming to and going from another machine on the same network through ettercap or ethereal that I get a lot of No buffer space available messages as following: SEND L3 ERROR: 1500 byte packet (0800:06) destined to 192.168.1.4 was not forwarded (libnet_write_raw_ipv4(): -1 bytes written (No buffer space available) ) I even was not able to nmap the other machine. I was trying to run these test over my iwi0 card and I'm on FreeBSD 6.1-RC While googling I found several posts about setting certain kernel parameters with sysctl and stuff can help but I didn't really get the clear picture of the problem and how it can be resolved, if it is considered a problem. Or is it the iwi0 doesn't handle much load? Thanks in advance for any input -- Sincerely, Yousef Raffah Senior Systems Administrator -- Aren't you using Firefox?
