netstat -M and netstat -N
While looking at the netstat man pages, I saw an interesting option: -MExtract values associated with the name list from the specified core instead of the default /dev/kmem. -NExtract the name list from the specified system instead of the default, which is the kernel image the system has booted from. what do these two options mean? Does it tell netstat to load its values from somewhere else? This seems to exist only in FreeBSD's version of netstat. Thanks in advance.

Detecting network memory leaks using netstat -m
Hi All, I'm trying to find out whether my ethernet driver is leaking. I just found out about netstat -m, but I don't understand some of it's output. Can somebody explain me what is "mbuf+clusters out of packet secondary zone in use" ? My output shows it raised significantly during equilibrium after several stress runs: BEFORE 16641/217734/234375 mbufs in use (current/cache/total) 16640/217766/234406/262144 mbuf clusters in use (current/cache/total/max) 256/1664 mbuf+clusters out of packet secondary zone in use (current/cache) AFTER 625083/86562/711645 mbufs in use (current/cache/total) 180264/81880/262144/262144 mbuf clusters in use (current/cache/total/max) 160420/311 mbuf+clusters out of packet secondary zone in use (current/cache) Thanks Yony ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

little lost with my netstat -m output
I have a couple of issues that I'm somewhat concerned about based on some netstat output results. I have a few boxes running 4.11-STABLE that provide this; FreeBSD 4.11-STABLE #0: Wed May 4 09:49:52 PDT 2005 (i386) # netstat -m netstat: sysctl: retrieving mbstat: Cannot allocate memory And then two boxes running 5.4-STABLE that provide this; FreeBSD 5.4-STABLE #0: Wed May 18 11:51:30 PDT 2005 (amd64) # netstat -m 1358787 mbufs in use 18446744073709476645/32768 mbuf clusters in use (current/max) 0/0/0 sfbufs in use (current/peak/max) 189754 KBytes allocated to network 0 requests for sfbufs denied 0 requests for sfbufs delayed 4735 requests for I/O initiated by sendfile 300 calls to protocol drain routines FreeBSD 5.4-STABLE #0: Wed May 18 11:51:18 PDT 2005 (amd64) # netstat -m 740238 mbufs in use 131702/32768 mbuf clusters in use (current/max) 0/0/0 sfbufs in use (current/peak/max) 448463 KBytes allocated to network 0 requests for sfbufs denied 0 requests for sfbufs delayed 10981 requests for I/O initiated by sendfile 492 calls to protocol drain routines Now, the 4.11 boxes failing to report and rather giving me a memory error are somewhat troubling, but what's more troubling is the 5.4 boxes showing current usage beyond the max limitations. Not to mention consuming between 190 and 450mb for net traffic. The output just seems so out of touch... While all the machines are frequented with attacks, none are in progress at the moment, and the machines rarely suffer anything more than lag due to network saturation... If this spike was the result of an attack, why were they never released? I'm generally confused by what I'm seeing here, what gives? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Yes: cd /usr/src/lib/libkvm && make obj && make depend && make && make install cd /usr/src/usr.bin/netstat && make obj && make depend && make && make install You may also need to rebuild systat, sockstat, netstat, lsof, and possibly other programs, which is why a buildworld is usually recommended. -- Dan Nelson [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

hi, it may not be your mbufs in the first place. confirm the integrity of your layer 1 first.
