accf_http and incqlen
I setup the http accept filter with apache and I was having a hard time understanding this, maybe you guys could help out. I've tested this among various version of freebsd, and with various apache configs, and it appears to behave the same across the board. So why is it that it appears that the TCP connections never terminate, just stay in a state of ESTABLISHED, and why doesn't this queue ever flush itself, is it normal, if it is, what happens exactly when the queue fills up to maxqlen. From the netstat output below, you can see that the incqlen is maxed out. I've done quite a bit of searching regarding this queue but haven't found any real solid information which describes what happens when it fills up, and at the same time this is going on, I have 517 established connections to port 80. ]# netstat -an|grep \.80|grep ESTAB|wc -l 519 ]# netstat -Lan Current listen queue sizes (qlen/incqlen/maxqlen) Proto Listen Local Address tcp4 0/0/5 *.8080 tcp4 0/510/511 *.80 tcp4 0/0/10 *.587 tcp4 0/0/10 *.25 tcp4 0/0/128*.22 tcp4 0/0/100*.3306 tcp4 0/0/9 *.21 tcp4 0/0/128127.0.0.1.953 tcp4 0/0/3 127.0.0.1.53 -Scott Oertel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks, I forgot also to mention systat, personally to keep track of CPU utilization, as in graphs, I use cacti which queries the servers using snmp, we also have a script which collects data from vmstat and stores it into a rrd, then we use rrdcgi to make pretty graphs with the data. -Scott Oertel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: awk question
Gary Kline wrote:
Guys,
Having found $9 , how do I /bin/rm it (using system()--yes??)
in an awk one-liner?
I'm trying to remove from packages from long ago and find and
print them with
ls -lt | awk '{if ($8 == 2006) print $9}';
but what I want to remove the file pointed at by $9. I've tried
FILE=ARGV[9]; and using FILE within my system() call, but no-joy.
What's the magic here?
thanks in advance,
gary
Another way is:
ls -lt | awk '{if ($8 == 2006) print rm -rf $9}' | sh
but I agree, using pkg_delete would be safer:
ls -lt | awk '{if ($8 == 2006) print pkg_delete $9}' | sh

Re: A webhosting script?
I wrote a simple one that could use improvement a while back for a FreeBSD box I had, you could use it as a reference point.

If its timestamp updates when you touch a file on the main filesystem, it's most likely a snapshot file, either leftover from a failed background fsck, or manually created by you with mksnap_ffs. You can just delete it.

The time stamp doesn't update, it gives an error: touch: #0005: Operation not permitted I mean touch some other file :) But I just remembered the correct way to determine if a file is a snapshot: ls -lo. If the flags field contains the word snapshot for that file, it's a snapshot. Good call, yeah.. it is a snap shot file, I suppose I'll try and remove it, hopefully removing a 450GB file doesn't lock up the system.. # ls -lo -r 1 root operator snapshot 482801995408 Jul 31 05:52 #0005 Thanks, Scott Oertel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
