Follow a port of a specific major verion
Hi list, I searched for this in the handbook, but without any hits. Google gave me nada too. I have a machine running FreeBSD 7.3 and Postfix 2.7.2 installed from ports. Unfortunately when I installed Postfix I did this: cd /usr/ports/mail/postfix make install clean Now when Postfix 2.8.0 is released the above path in the ports tree points to a Postfix version I do not yet want to install. I would like to follow Postfix 2.7.x for a while. So my question is: How can I make the ports system act as if I had installed Postfix like this?: cd /usr/ports/mail/postfix27 make install clean Is there a way to tell the ports database to follow and older version of Postfix without rebuild the entire port again?

I'm pretty sure you can't do this, *unless* there's someone actually tracking a seperate port on that version. ( i didn't check but it doesn't sound like it from your post). To stop ports tree updates from clobbering your v27, you'd need to exclude this from your cvssup or whatever you use to update your tree. portdowngrade will get you back to an arbitrary older version if your tree already has the newer version.

STATEs that aren't in caps are either wait channels or mutexes, and their initialization is scattered all over the kernel. There isn't one comprehensive index. usem sounds like maybe a semaphore operation? A quick grep of the kernel doesn't show any strings starting with usem, though. Maybe if you run procstat -k pid on one of those processes you can narrow down what part of the kernel it's waiting in. -- Dan Nelson dnel...@allantgroup.com ___ 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

How to count number of connections from nginx workers to php-cgi unix socket?
I need to count number of connections to php's cgi unix socket (created with spawn-fci). When nginx initiates a connection to cgi socket one of spawned php processes accepts this connection, processes input and outputs data. But number of processes is limited and i want to be able to monitor amount of free processes. I tried all available tools (netstat, sockstat even lsof) but it seems there is no way to determine how many active connections from nginx to unix socket.

Yes! Dreams do come true or maybe just partly.
Years ago, like late 1990's or very early 2000's, there was an
effort to use the strengths of both operating systems: the
unsurpassed stability of BSD along with the goodies you find in
Linux. I mostly did cheerleading but when things stalled I got
busy porting the FBSD libc. I was about 17% done w hen I
stopped this Debian FreeBSD. You can google around and find
stuff about the project.
{
Begin slight diversion::
IIRC, the main point of contention involved the differences
between the GNU CopyLeft and the freerer BSD Copyright. For [at
least one] of my projects, muuz, I even invented my own
copyright. And then there are many, many other means of sharing
stuff. My electronic novel, altho copyright by the Lib of
Congress does not have any Digital *Wrongs* Management. ---That's
my tiny contribution. So you can buy one copy of JOURNEY/DAWN for
$9.47 and share it around the way I share my boughten books and
music CD's and DVD's.
End slight diversion;
}
I haven't heard anything about somebody picking up the idea on
integrating Debian Linux and FreeBSD, so unless Zeus stabbed
hisself in the back while about to hurl a lightening bolt, don't
worry.

I went around the office polling _really_ old UNIX hands before making the above statement). I used to believe that until I was shown I was wrong. The easiest way to see you're wrong is to drop to ttyv0 then do one of each like a reboot then a shutdown -r now. In the latter case, you'll notice /etc/rc.d/ and /usr/local/etc/rc.d/ stop scripts being processed but not so in the former. In both types of shutdowns, everything *should* exit cleanly but processes are terminated with different signals and certain types of applications really need the full rc stop script to end cleanly like HAST and CARP for example. shutdown -r/p is a really good habit to form. FWIW, someone also stated reboot on Linux behaves like shutdown -r now so that I sure contributes to the confusion. -- Adam Vande More ___ 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
Terminal Server/BREAK_TO_DEBUGGER
Hi there, I'm trying to break a FreeBSD/i386 machine into the debugger via serial console connected to an older Avocent CPS 1600 serial terminal server. I'm using cu on another FreeBSD/i386 machine to connect to one of the other serial ports of the Avocent. The CPS offers a port break command for creating a break condition on an attached serial port, but that doesn't trigger anything on the receiving FreeBSD machine. Using a direct serial connection (just 2x3, GND) between the machines works, though. I realize this being quite a long shot -- Someone ever used such a box successfuly for the purpose ?

It's quite easy to see you're wrong, just follow the steps I outlined above. If you are correct, reboot(8) should print things like: Stopping sshd. to the console. It doesn't and shutdown(8) does so the proof is right there. The reboot man page only hints at it though unfortunately which caused my initial confusion(in addition to the permissions mismatch between the two). Normally, the shutdown(8) utility is used when the system needs to be halted or restarted, giving users advance warning of their impending doom and cleanly terminating specific programs. You can also reference init.c if you still think you're correct. In addition, please read carefully through this thread and then examine your arguments vs what is reality and then we can all be on the same page. http://lists.freebsd.org/pipermail/freebsd-stable/2010-December/060519.html -- Adam Vande More ___ 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
Re: shutdown computer after the halt command
It's quite easy to see you're wrong, just follow the steps I outlined above. If you are correct, reboot(8) should print things like: Stopping sshd. to the console. Sigh. I shut down my FreeBSD 8.1 laptop all the time with halt -p, and I can assure you it prints all those messages. You can also reference init.c if you still think you're correct. No thanks, I've already read the man page for init, including this paragraph: When shutting down the machine, init will try to run the /etc/rc.shutdown script. This script can be used to cleanly terminate specific programs such as innd (the InterNetNews server). If this script does not termi- nate within 120 seconds, init will terminate it. The timeout can be con- figured via the sysctl(8) variable kern.init_shutdown_timeout. If you're unfamiliar with rc.shutdown, it also has a man page. Perhaps your copy of FreeBSD was installed incorrectly, or it's been so long since you tried halt or reboot that you forgot what happened.

Re: shutdown computer after the halt command
Hmmn, I looked at the code and by golly you're right, halt/reboot doesn't poke init. Nonetheless, I really do see a lot of foo stopping messages when I use halt, presumably because the SIGTERM that halt/reboot sends has the same effect (if not the same ordering) as the ones that the various rc.d scripts send. Looks like init 0 would be tidier than halt -p, and in the finest Unix tradition, is one less character to type.

VESA and SDL in tty terminal
Hello, The SDL's pkg-message says we can use video driver in tty terminal. To do this you have to load the vesa kernel module or enable it in your kernel, and set environment variable SDL_VIDEODRIVER=vgl.
