Your trying to run too many memory hungry applications at same time. Tweaking the kernel is not going to help you. Adding more ram will. Better to only run single network monitoring application at a time. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org]On Behalf Of Yousef Raffah Sent: Monday, April 24, 2006 3:33 AM To: freebsd-questions@freebsd.org Subject: No Buffer Space Available Hello.. 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? Get it at http://www.getfirefox.com
