kern.maxdsiz big memory/tuning questions
Hello, I'm trying to RTFM but the M does not appear to exist. I am dealing with processes over 512MB in size on 6.0 on x86 and am using these loader.conf tunables as suggested by MySQL and other documentation: kern.maxdsiz=1073741824 # 1GB kern.dfldsiz=1073741824 # 1GB kern.maxssiz=134217728 # 128MB I can glean so far that: 1. You don't want to exceed physical memory with these 2. These are listed in /boot/defaults/loader.conf 3. This is not controlled by sysctls :) 4. 'limits' will show what they are currently set to However, I am not clear if: 1. It is permitted to use M and G notation (kern.maxsiz=1G)? - some say yes, some say no and I would prefer not risk the system not booting. 2. Which tunables actually matter beyond kern.maxdsiz? Some say only kern.maxdsiz and some suggest all three. 'man tuning' and the handbook (~/handbook/configtuning-kernel-limits.html) only goes into maxfiles and maxusers. Searches of this list and Google have yeilded what you see above. Could someone please share some wisdom or docs on this matter? Much appreciated, Michael. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: /etc/mail/local-host-names
to enable anybody in IPv4 10.0.0.0/8 to relay through this server 10. seems not to work. I think--but don't *quote* me:) -- that the host-names file does eactly what ^Cwhostname does in sendmail.cf. So if your host were named foo, you would put ^foo in local-host-names. Anybody else? i thought it's like sendmail.cw - even in .mc file it's said that's just different filename. things worked different in NetBSD (sendmail 8.13.3) than in FreeBSD 6.0 (8.13.4). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

pine
Hi everyone,
I am having some problems setting up pine .pinerc using
FreeBSD 6.0 - STABLE. My ISP uses POP and I am using thier SMTP for
outgoing. I spoke to the helpdesk and the POP server does not support ssl.
Pine was compiled and installed with support for POP3
here are some lines from my .pinerc;
smtp-server=mail.myisp.net.au
inbox-path={pop.myisp.net.au/pop3}inbox
When I launch pine with the above settings Pine uses INSECURE login and
password. Even though the login is INSECURE, I can access my mail and use
newsgroups.
I have tried using;
inbox-path={pop.myisp.net.au/pop3/secure}inbox
but when I launch pine I get the error message;
'Can't do secure authentication with this server'
If you can offer advice could you please CC me as I am not subscribed to
the questions list. I know this question is not an OS question, but I
do not like the idea of sending my login details unencrypted through
the ISP network.
Thankyou,
caleb

Re: version 6!
After realizing how long I made this little explanation, I decided it might be helpful to someone if I made it available on the freebsd-questions mailing list. List: take the following for what it's worth. On Tuesday 13 December 2005 07:00 pm, ntkonn wrote: Crap amighty, I just upgraded FreeBSD. When did they go to 6? Yes, 6. You might want to consider subscribing to the freebsd-announce mailing list (http://lists.freebsd.org/mailman/listinfo/freebsd-announce). Also, the release of FreeBSD 6.0 does not mean you are running an outdated version of FreeBSD (yet). The 5.x branch is basically in maintenance mode, but a 5.5 release is planned. I doubt that 5.x will be retired before 6.1 has been out for a while. Are you running 6? Anything in it make it worth the trouble to upgrade? Should I upgrade just so I don't get too far behind? FreeBSD 6.0-RELEASE breaks the mold for a dot nought release in that it is both relatively painless to upgrade and quite stable to run. Take a look at http://www.freebsd.org/releases/, and pay particular attention to the announcement and release notes for 6.0. As for reasons to upgrade, you can determine that yourself from the release notes, etc., but in my view there's no good reason not to. Not lagging behind is also a good way to go in general. The best (read: non-adventurous) way to do that is to follow releases, or possibly by tracking -STABLE. (Releases are merely extra-well-tested, nicely packaged snapshots of the -STABLE branch of development.) (If you're curious, the adventurous way to stay current is to track -CURRENT. All new (and possibly untested) development happens in -CURRENT, and is backported to -STABLE only if it doesn't break compatibility and after it has been tested for a set period of time.) See also http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html (and the rest of chapter 20 of the handbook). As I alluded to in my prior e-mail, I am running 6-STABLE both at home and at work with no problems. 6.0-RELEASE is also a good modern-but-not-scary candidate. uname -a produces: FreeBSD asus.konneker 5.4-STABLE FreeBSD 5.4-STABLE #0: Wed Nov 2 19:13:15 EST 2005 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC i386 That means you're running 5-STABLE from a little over a month ago. The gap between 5 and 6 is pretty narrow at this point, but it will probably widen with time (little if any new development is making its way into 5, since 6 is now stable). You can do one of four things (actually 5, but the 5th is not recommended): 1) Not upgrade your system. Not recommended for long-term use, but not necessarily a bad thing at any given time. Plan on doing one of the other options, but use this one until it's convenient to upgrade. 2) Continue tracking 5-STABLE. You could update your sources to the latest in the 5.x branch, using cvsup and a src supfile with the RELENG_5 tag. Rebuilding your world and kernel at that point would give you a 5-STABLE with today's date. This option is better than (1) above, since it will incorporate security and other critical fixes, but still doesn't get you very far in terms of new functionality or staying up-to-date. This option could also be a useful stepping-stone prior to upgrading to 6, but since your current system is very close to this already it's not strictly necessary. If you wait a while to upgrade to 6, then you will definitely want to upgrade to the most current 5-STABLE beforehand. 3) Upgrade to 6.0-RELEASE. This is most easily done by changing the tag in your src supfile to RELENG_6_0, updating your sources, and rebuilding world and kernel. You will likely also need to rebuild/reinstall most or all of your ports to reflect new versions of the system libraries (this step is only typical of upgrades across major release numbers (like 5 to 6) and is not necessary for minor release upgrades (like 6.0 to 6.1). This is a strong option, since it gives you a well-tested release and keeps you from needing to do a major version upgrade for the entire lifecycle of FreeBSD 6.x. Even if you go with (4) below, you should do this first. 4) Upgrade to 6-STABLE. To do this you would change the tag in your src supfile to RELENG_6. The main advantage of this option is that you can do many incremental updates. This allows you to get new features without waiting for the next release, and also lets you deal with potential bumps in the upgrade path in smaller doses. There is the added risk (compared to (3) of encountering bugs or other hurdles that might not show up in a release, but in my experience that risk is minimal. 5) (Listed for completeness only. Typically only experienced (and/or brave/benevolent/eager, etc.) users wishing to be actively engaged in the development and testing process should do this.) Upgrade to 7-CURRENT. You would do this by changing the tag in your src supfile to . (just a period,

I need a better way to loop in the shell...
I always do loops in /bin/sh like this: for f in `cat file` ; do rm -rf $f ; done Easy. I like doing it like this. The problem is, when I am dealing with an input list that has multiple words per line, this chops it up and treats every word as a new line... For instance, lets say I have a file full of filenames, like this: # cat file 10,000 Maniacs MTV Unplugged - 01 - These Are Days.mp3 10,000 Maniacs MTV Unplugged - 02 - Eat For Two.mp3 10,000 Maniacs MTV Unplugged - 03 - Candy Everybody Wants.mp3 and I try to use the above loop on it, it thinks that every word is a line ... the above loop will attempt to delete the following files: 10,000 Maniacs MTV Unplugged - 01 - These (and so on) Even if I quote the variable $f, like: for f in `cat file` ; do rm -rf $f ; done it still does the same thing. - So my question is, what is a nice simple way to loop in the shell, as close to what I am doing above as possible, that does not have this problem ? Should I just be using something other than `cat` ? Or what ?

RE: Lousy network performance ...
Turn on SNMP on your router plugged into the adsl modem and use a tool like mrtg to graph the circuit utilization. Also, access your adsl modem's error counters and find out what your signal to noise ratio is, what your received decibel level is, if your taking errors, and such. Some of the consumer modems do not have these counters accessible and can only be queried via the DSLAM operator. Your service provider is right to push the problem back to you because it almost certainly is not their network. If it was their network you would notice a definite change at different time of days - if they are overloaded then at 4:00am you should get lightning speed. If your DSL sucks at that time then it's your problem, not their network. Unfortunately for you, however, your service provider didn't explain to you what you need to do to properly troubleshoot this. It could possibly be that you ASSUMED the problem was their network and pissed them off when you called in. I would suggest you call them again, politely, and ask, not demand, that they check signal levels and error counters on your phone line. If they can't do this then have them refer you to the telco that can. One other piece of advice for you, if your goal is to prove the ISP is wrong then you ought to just find another ISP. Your goal should be to find out the cause of the slowness, not in assessing blame. If your using a consumer ISP it is likely the first level tech support people probably cannot help you since their main job is helping people fix their misguided PC desktops, and they usually aren't even allowed to touch the back end equipment. But they can in fact hurt you badly by simply not passing you to the upper-level tech people who could help you. So, be nice to them.

THIS IS NOT LOAD BALANCING PLEASE QUIT BEING SLOPPY WITH YOUR NETWORKING TERMS I refer you to the pfsense website itself: http://faq.pfsense.org/index.php?sid=13525lang=enaction=artikelcat=6; id=18artlang=en Load balancing is on per connection basis, not a bandwidth basis. All packets in a given flow will go over only one link. In other words, they are redefining the term load balancing into something that is not understood by any previously accepted definition of load balancing, so that people like you can think your getting something for nothing. Once more - FTP to a remote site with your dual DSL links. Copy a FreeBSD ISO file to there. Watch as the upload speed IS NO FASTER THAN ONE OF THE LINKS. Ted I just looked at the pfsense site, and for an Internet Café, it looks promising. Two DSL lines to different ISP's does give a small amount of redundancy. Whether you use two routers or pfsense, you get some sort of load sharing but not load balancing. A more appropriate performance test for an Internet Café would be: Take a dozen PC's each to transfer a FreeBSD 6.0R ISO file from a dozen different mirror sites. Start them at the same time and see how long the all of the transfers take. You can test one DSL connection at N kbps and two DSL connections both at N kbps. You'll undoubtedly see the effect of load sharing if the dozen PC's are more or less evenly divided over the two DSL lines. The redundancy isn't great, and you will pay for it. Namely, two N kbps connections will cost you more than one 2N connection. If you ran my benchmark on a 2N connection you might actually see an improvement over two N kbps connections due to to its inherent load balancing. In any case, with a single (or a small number) of users (Ted's benchmark test) you would definitely see an improvement over two N kbps connections. Now the question: is a faster AND cheaper 2N connection a better setup than two N kbps connections for our fabled Internet Café? NO. As I pointed out the MOST COMMON failure mode on DSL is SLOWNESS not DISCONNECTS. If you have a 2N connection and one of the DSL modems starts going gunnysack, you are really going to have to know your stuff to be able to detect this and fix it. If the modem picks 9:35pm at night to do this, or some other inconvenient time, like seems to be the normal time for failures to happen, I guarentee your not going to get anyone at the ISP who knows shit from shinola to help you, and your going to be spinning your wheels. For the fabled Internet Cafe, really and truly and honestly, the crude solution that the previous owner worked out is the best - it is easy for relatively unsophisticated people (such as the minimum wage high school student you hired to watch the place after school) to troubleshoot, it is easy to get assistance from the ISP on the failed leg, since the configuration is very basic and standard, and it is dirt cheap. I realize the temptation to mess with a running setup is strong, and the temptation to change around something you buy so as to put your own stamp on it is even stronger. But it is a great way to have terrible monsters come storming out of the closet that the existing config was developed to work around. I'd personally go with the 2N connection. Almost all the time it would be better. Most large ISPs, for a little more money of course, will give you a faster response time on repairs. The ISP might even provide a bank of modems and you could implement multilink PPP as your backup. 2N is great if you need to ship large data items around and your site is way far away from the DSLAM. But it is more complex and so you need to be using it when the big guns both at the ISP and the organization are not in bed - meaning 9-5 - so that if problems happen they are available to get them solved.

This is hardware dependent and cannot be changed. It takes a certain amount of time to get the packet out of the hardware in the ethernet card into main ram, this also hardware dependent and cannot be changed. (unless the device driver is terribly inefficient, which we will assume it's not) Once in main ram, the information in the packet has to go through a number of code statements. The more code statements the longer the information in the packet is sitting around in the FreeBSD system's memory. It then takes a certain amount of time to get the information out of main memory into the other sending ethernet nic's buffers, and it takes time to get it out of the sending nic back to the wire. Danial is claiming the slowness is in the main ram section of things, not in the ethernet driver code. polling makes the ethernet driver more efficient at high data rates, but it does nothing for the speed of processing within the TCPIP stack itself. At low data rates polling is less efficient than the interrupt method. And unless the nic driver is terribly inefficient to start with, the time it adds to the packet path in the system is minor compared to the time spent in the TCP/IP stack. Ted Thanks for the explanation. So would polling be beneficial or detrimental for a 100 mbps Ethernet card? Yes, if you were running 100Mbt's of bandwidth through it. I assume you mean yes it's beneficial? :) Yes. :-) Not sure if 100 mbps is considered high or low speed. I'm specifically interested in NetGear cards using the dc driver or DLink cards using the rl driver. The rl chipset isn't known as a very good chipset. YMMV Yeah, I've heard that a lot. It was an old card I had lying around and it seems to work OK for me. I'm not using it for anything other that connecting to a 802.11b wireless bridge. Very little traffic. This post is passing through 2 of these cards on my home BSD router. Fortunately these days since so many mboards are coming with onboard ethernet, the used market is awash in nice PCI ethernet cards. Some of the Netgear cards use clone 21143 chipsets which are extremely inferior to the real thing. In particular if your Netgear card is using a PNIC chipset it is pretty bad with serious performance penalty. This is documented in Section 4 of the dc manpage. This is disapointing. I was under the impression that NetGear cards were pretty good. But now I looked closer at dmesg.boot and see I have the PNIC chipset you mention. I'll read the dc man page to see what penalties I'm suffering. People seem to have good results with polling on the fxp cards. Ah, the built in interface on a HP e60 server I have. It's an old dog used as a file server. It has been nothing but reliable and is still chuggin' along just fine. I'll enable polling on it and see if there's any noticeable improvement in transfer rates. The machine that typically is used for large file transfers to and from the e60 is a Windows XP box that has a Nvidia Nforce 4 chipset and whatever intergrated ethernet port that comes with that chipset. Are there any known issues with this setup that would invalidate my test? Yes. The old dog may not be able to take packets off the fxp chip fast enough if your hitting it with 100Mbt of data - which your Nforce chipset running on a nice new multigigahertz mboard is probably able to do. This is a CPU speed thing not an architecture thing, and polling won't make any difference. But, OTOH, windows is pretty inefficient so the network performance of a multigigahertz windows box might just equal that of a under-a-gigahertz mboard running UNIX.
