Hi all,
What is the best way to capture packets on 250mb link?
What kernel features/modules or tools (less CPU/RAM overhead) should I use?
I have FreeBSD 7.0-STABLE machine (
CPU: Intel(R) Xeon(TM) CPU 2.80GHz (2822.51-MHz 686-class CPU),
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
1GM RAM, ad2: 76319MB <Maxtor 6L080M0 BANC1G10> at ata1-master SATA150).
#uname -an
FreeBSD ng1.micom.mng.net 7.0-STABLE FreeBSD 7.0-STABLE #3: Sat Apr 26
14:08:06 ULAT 2008 tsgan@ng1.micom.mng.net:/usr/obj/usr/src/sys/NG i386
#pciconf -lv|more
...
bge0@pci0:2:0:0: class=0x020000 card=0x1659103c chip=0x165914e4
rev=0x11 hdr=0x00
vendor = 'Broadcom Corporation'
device = 'BCM5721 NetXtreme Gigabit Ethernet PCI Express'
class = network
subclass = ethernet
...
Are there any considerations on hardware?
thanks in advance,
Ganbold
