Makefile OPTIONS (was: Re: Apache 2.2.8 + mod_authnz_ldap)
What are you using for apr? The one that comes with apache itself, or the devel/apr port? AFAICT, the one that comes with Apache itself. It would seem that mod_authnz_ldap required mod_ldap to be compiled in Apache to work. Having little or no experience at all with Apache + LDAP combination so far, this was not really straightforward to me. However, that combined with the (relatively) recent introduction of OPTIONS to apache22 port leads me to ask the question if the Makefile OPTIONS framework allows for dependencies (i.e. I mark one, the framework automatically ticks other options my selection depends on). Or, in this case, selecting mod_authnz_ldap automatically selects mod_ldap. From the (scarce) documentation in the Porters Handbook, it would seem that this is not currently possible, yet it doesn't seem impossible to invoke another dialog and warn the user about inclusion of additional options.

Questions from a Total samba Novice.
I just found out that I will need to copy some files from a FreeBSD system to a Windows shared drive on our network so that Windows users can have access to the files. After reading a little documentation and talking to a cowworker, I was under the impression that this would allow windows clients to access files on the FreeBSD system, kind of the reverse of what I wanted. Then I read the man page for the samba suite and it says: smbclient(1) The smbclient program implements a simple ftp-like client. This is useful for accessing SMB shares on other compatible servers (such as Windows NT), and can also be used to allow a UNIX box to print to a printer attached to any SMB server (such as a PC running Windows NT). That sounds like I could push a file across when needed and be done with it rather than trying to coordinate the remote users to get the file at some time after I left it in a given directory. Is that just wishful thinking or will it work that way when properly configured? I need to be able to tell others in this group what is possible and that one little paragraph seems to say one can copy out from the UNIX box to the shared drive. Any particular gotchas regarding XP which soon will be Vista in this neck of the woods? I apologize for some of the dumb questions as I do not personally use Windows. I use FreeBSD, Mac and Linux. We have a huge Windows base on our campus, however, so for now, I need to export some log files to the Windows world. Thanks for any useful ideas and for your patience.

Re: Questions from a Total samba Novice.
(forgot to send to list the first time) Hi Martin, You don't need samba if all you want to do is copy files from FreeBSD to a Windows system. The easiest way to do it is to mount an existing Windows share, on FreeBSD. This will give you access to the Windows share, but nothing is shared out on your FreeBSD box. Let's assume you have a non-protected share (called MYSHARE) on a Windows server called FRED. Let's also assume you have prepared a mount point on FreeBSD for this share, called /mnt/fred. All you need to do is: $ mount -t smbfs //FRED/MYSHARE /mnt/fred If you need to specify a username/password combo to access the share, try: $ mount -t smbfs //[EMAIL PROTECTED]/MYSHARE /mnt/fred You will need to input a password, but if you want to save the password so it's used automatically, use /etc/nsmb.conf (see the man page), but here's an example. [SNAP-CMS] addr=192.168.0.4 [SNAP-CMS:BACKUP] password=$$14b5d4732371b1c00e5d2f5cd96 The hashed password was created by using 'smbutil crypt' and inputting the real password (see the man page). Obviously you need to make sure the permissions on /etc/nsmb.conf are secure. If you want it to automount at startup, then /etc/fstab could contain: //[EMAIL PROTECTED]/MYSHARE /mnt/fred smbfs rw 0 0 Cheers, Steve :) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

FBSD 6.2 Xeon 2.4ghz CPU and high load
Good morning. I recently upgraded our two email gateways from 4.8 to 6.2. The required software was upgraded as well which consists of MailScanner and Sendmail. Both had been keep up to date so it was not a jump in required resources. The issue I am seeing is that my server load, under the same traffic load, has increased 4 times or more. Where previously we saw a high load on the servers of 5 to 8, we are now seeing 14 to 17. Since the upgrade Sendmail has begun to timeout connections. I have been digging through the system, mail lists, forums, anything to help determine the cause of the increased load. Here are some examples of what I am seeing. bash-2.05b# vmstat -w2 procs memory pagedisks faults cpu r b w avmfre flt re pi po fr sr da0 da1 in sy cs us sy id 12 5 0 2234516 199864 772 4 0 4 431 447 0 0 485 564 927 29 4 67 11 6 0 2229788 181352 8631 0 0 0 5597 0 0 0 294 2592 1236 45 5 50 9 5 0 2227208 168144 6456 0 0 0 4607 0 2 0 278 1333 898 46 4 50 11 5 0 2229068 175868 5164 0 0 0 5423 0 0 0 212 766 541 47 3 50 14 7 0 1948392 236296 8136 0 0 0 12382 0 14 0 368 4135 1504 42 8 50 4 3 2 1744620 321024 7550 0 0 0 13454 0 23 6 752 11417 3919 42 8 50 12 5 0 1951788 258944 12490 0 0 0 11295 0 0 5 727 18566 4844 40 10 50 16 6 0 2155668 214324 8231 0 0 0 4230 0 1 29 724 15531 4381 41 9 50 8 6 1 2044828 242084 4567 0 0 0 9119 0 0 12 774 12196 3225 43 7 50 bash-2.05b# top last pid: 85205; load averages: 12.89, 13.78, 14.66 up 47+15:51:31 15:20:01 126 processes: 12 running, 79 sleeping, 35 zombie CPU states: 43.8% user, 0.0% nice, 6.3% system, 0.0% interrupt, 50.0% idle Mem: 1008M Active, 582M Inact, 211M Wired, 78M Cache, 112M Buf, 122M Free Swap: 4096M Total, 304M Used, 3792M Free, 7% Inuse I am suspicious of the kernel being the culprit because the system looks as if it is not working very hard, CPU load never shows above 50% idle.

Is this a known issue I can easily correct? At this point I am left with either rolling back to 4.11 or trying another OS.

Re: Makefile OPTIONS (was: Re: Apache 2.2.8 + mod_authnz_ldap)
If this is a fixed dependency, then it's a bug in the port's Makefile. If it's not set in stone (i.e.: mod_authnz_ldap could also work with mod_fictional_3rdparty_ldap), then applying the logic you suggest, would kill the option to use mod_fictional_3rdparty_ldap. Set in stone would mean, if there is a port mod_fictional_3rdparty_ldap, or enough people have complained that they cannot use mod_fictional_3rdparty_ldap, even though there's not a port for it. It seems that the main problem arises from usage of OPTIONS. If I had specified WITH_LDAP_MODULES (a category), both modules (ldap and authnz_ldap) would have been included. If I had specified WITH_LDAP, according to 'make show-options', it would have implied the option WITH_LDAP_MODULES. However, when modules are selected through OPTIONS dialog, AUTHNZ_LDAP means just AUTHNZ_LDAP and LDAP means just LDAP. Theoretically, this is not an error in port's Makefile, rather something that gives even more flexibility to the user. However, the same can't be said for user-friendliness. And to comment on your message, I see no other LDAP-related options in Apache which would make this a fixed dependency.

Re: Questions from a Total samba Novice.
Hi Martin, I would have had to enabled nfs client if using mount_smbfs, correct? Nopes - stick to using the mount command. Depending on the filesystem you specify (with the -t option), it will call the relevant mount command itself (eg. mount_smbfs, mount_nfs). When I built the system in question, I did not enable nfs capabilities and don't really want to if I can avoid doing so. You don't need it. It sounds like smbclient fits the bill for now, but thanks to all of you for making things more clear. It seems that /usr/ports/net/samba3 gives one a whole boatload of possibilities. Although installing samba will give you smbclient and a load of other things, if you don't need them I wouldn't install it. From what you've previously explained, everything can be done with the (already supplied) mount command.

How to get best results from FreeBSD-questions
How to get the best results from FreeBSD questions. === Last update $Date: 2005/08/10 02:21:44 $ This is a regular posting to the FreeBSD questions mailing list. If you got it in answer to a message you sent, it means that the sender thinks that at least one of the following things was wrong with your message: - You left out a subject line, or the subject line was not appropriate. - You formatted it in such a way that it was difficult to read. - You asked more than one unrelated question in one message. - You sent out a message with an incorrect date, time or time zone. - You sent out the same message more than once. - You sent an 'unsubscribe' message to FreeBSD-questions. If you have done any of these things, there is a good chance that you will get more than one copy of this message from different people. Read on, and your next message will be more successful. This document is also available on the web at http://www.lemis.com/questions.html. = Contents: I:Introduction II: How to unsubscribe from FreeBSD-questions III: Should I ask -questions or -hackers? IV: How to submit a question to FreeBSD-questions V:How to answer a question to FreeBSD-questions I: Introduction === This is a regular posting aimed to help both those seeking advice from FreeBSD-questions (the newcomers), and also those who answer the questions (the hackers). Note that the term hacker has nothing to do with breaking into other people's computers. The correct term for the latter activity is cracker, but the popular press hasn't found out yet. The FreeBSD hackers disapprove strongly of cracking security, and have nothing to do with it. In the past, there has been some friction which stems from the different viewpoints of the two groups. The newcomers accused the hackers of being arrogant, stuck-up, and unhelpful, while the hackers accused the newcomers of being stupid, unable to read plain English, and expecting everything to be handed to them on a silver platter. Of course, there's an element of truth in both these claims, but for the most part these viewpoints come from a sense of frustration. In this document, I'd like to do something to relieve this frustration and help everybody get better results from FreeBSD-questions. In the following section, I recommend how to submit a question; after that, we'll look at how to answer one. II: How to unsubscribe from FreeBSD-questions == When you subscribed to FreeBSD-questions, you got a welcome message from [EMAIL PROTECTED] In this message, amongst other things, it told you how to unsubscribe. Here's a typical message: Welcome to the freebsd-questions@freebsd.org mailing list! If you ever want to unsubscribe or change your options (eg, switch to or from digest mode, change your password, etc.), visit your subscription page at: http://lists.freebsd.org/mailman/options/freebsd-questions/[EMAIL PROTECTED] (obviously, substitute your mail address for [EMAIL PROTECTED]). You can also make such adjustments via email by sending a message to: [EMAIL PROTECTED] with the word 'help' in the subject or body (don't include the quotes), and you will get back a message with instructions. You must know your password to change your options (including changing the password, itself) or to unsubscribe. Normally, Mailman will remind you of your freebsd.org mailing list passwords once every month, although you can disable this if you prefer. This reminder will also include instructions on how to unsubscribe or change your account options. There is also a button on your options page that will email your current password to you. Here's the general information for the list you've subscribed to, in case you don't already have it: FREEBSD-QUESTIONS User questions This is the mailing list for questions about FreeBSD. You should not send how to questions to the technical lists unless you consider the question to be pretty technical. Normally, unsubscribing is even simpler than the message suggests: you don't need to specify your mail ID unless it is different from the one which you specified when you subscribed. If Majordomo replies and tells you (incorrectly) that you're not on the list, this may mean one of two things: 1. You have changed your mail ID since you subscribed. That's where keeping the original message from majordomo comes in handy. For example, the sample message above shows my mail ID as [EMAIL PROTECTED] Since then, I have changed it to [EMAIL PROTECTED] If I were to try to remove [EMAIL PROTECTED] from the list, it would fail: I would have to specify the name with which I joined. 2.

The Complete FreeBSD: errata and addenda
The trouble with books is that you can't update them the way you can a web page or any other online documentation. The result is that most leading edge computer books are out of date almost before they are printed. Unfortunately, The Complete FreeBSD, published by O'Reilly, is no exception. Inevitably, a number of bugs and changes have surfaced. The Complete FreeBSD has been through a total of five editions, including its predecessor Installing and Running FreeBSD. Two of these have been reprinted with corrections. I maintain a series of errata pages. Start at http://www.lemis.com/errata-4.html to find out how to get the errata information. Note also that the book has now been released for free download in PDF form. Instead of downloading the changed pages, you may prefer to download the entire book. See http://www.lemis.com/grog/Documentation/CFBSD/ for more information. Have you found a problem with the book, or maybe something confusing?

You should evaluate SCHED_4BSD vs. SCHED_ULE for your workload. SCHED_4BSD is still the default in 7.0, but SCHED_ULE gives better numbers for many workloads, and it only missed being the default in 7.0 because it hadn't had enough time to settle into the tree before the release. SCHED_ULE will be the default from 7.1 onwards.

You should look more into the status of the various processes, and how long it takes your mail scanning to process a message compared to previously. It might be the case that the config under 6.2 is allowing more instances to run at once and is just barely nudging the system into excessive paging.

mounting linux partitions
I have installed a linux distro on a partition of my machine (latest Mandriva i686, default installation). I only need it to use a piece of software for Nikon Coolscan IV film scanner (yes, sane works, but a cheap commercial package called vuescan has better interface and uses some hardware features like infrared channel that sane does not support, at least in current stable version). Now I would like to mount ext3 partition from FreeBSD at least for reading, or vice versa, UFS2 from linux for writing. With kernel option EXT2FS, I can $ mount -t etx2fs /dev/ad12s7 /linux but then if I do $ ls /linux I get a 'Bad file descriptor' for directory /linux. e2fsprogs are installed, and fsck.ext2 or fsck.ext3 think well of the partition. Also, df seems to show it correctly, with size and free space. I have FreeBSD 7.0 for amd64, Linux is 32-bit version. Also the partition is 'extended', i.e. fdisk on FreeBSD shows a DOS partition, but linux's fdisk shows a couple of ext3 partitions. However, /dev/ad12s7 does correspond to the correct linux partition and, when mounted, df shows the right size and utilization. Any advice how to share a partition between these 2 systems? I only want to use linux to scan the film and store the pictures on disk, then boot into FreeBSD where I spend most of my life as a user. I feel more comfortable pulling from FreeBSD rather than pushing to it because (1) it is easier for me to recompile FreeBSD kernel or install packages if necessary, and (2) I would mind much less a corruption on the linux partition than on UFS; I can simply reinstall the default installation for Linux, but FreeBSD has important data and is finely tuned for me over the years. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

freebsd7 on older machines
i can't seem to boot the cdrom on older hardware (500MHz and down). i read somewhere that the older drives aren't supported by the installation cdrom. i want to create a series of 'dumb terminals' which can ssh -Y into a faster machine. if necessary i suppose i can floppy in and then install via nfs. or i can setup the hd on another machine that does support the install cdrom and then transfer to the older machine. here are the specific questions: 1. do older machines work better with older versions of freebsd? 2. if i dd a hd (with freebsd) onto another hd will i have a problem with the mbr and be unable to boot? 3. are there any other ideas for install? -- In friendship, prad ... with you on your journey Towards Freedom http://www.towardsfreedom.com (website) Information, Inspiration, Imagination - truly a site for soaring I's ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: slapd won't start with nss_ldap.conf

I just copied ldap.conf to nss_ldap.conf, see contents below. To try and identify the problem, can I ask - when you say slapd doesn't start, how long have you waited? There is a chicken-and-egg problem with slapd on a host which is running nss_ldap. To start a process, the system has to adopt the user and group privileges of the process owner, which means enumerating all the groups for that user from every source of group information - including LDAP on a system running nss_ldap. So, to start slapd, the system needs the group info for user ldap - from slapd. It times out and retries a few times, and eventually starts slapd using the group information from /etc/passwd and /etc/group, but the timeout and retry options by default take several minutes. The delay can be even longer depending how many other services are being started first and therefore how many nss_ldap lookup timeouts occur during boot. There are a number of possible solutions depending which version of nss_ldap you're running - searching for nss_ldap bind_policy nss_reconnect_tries will produce a number of suggestions and ``problem reports''.

You may have old motheboards (or BIOS) that do not support el-torito (no emulation) boot, i.e. they can only boot from CD like a floppy (think Windows 98 CD boot). In this case booting from floppies will allow you to start (installation will continue from CD). It is not fast, but it works. A friend of mine is running a 6.3-RELEASE (obviously console only) on a 200 Mhz Pentium with 48Mb or RAM. It performs reasonably well for this spec (as long as you don't compile anything). I once installed 6.1 on a Pentium Pro, 64Mb RAM using floppies + CD, it worked. Even got X running! I have successfully installed 7.0 on an AMD K6-2 500Mhz - had to disable ACPI or weird things would happen. Haven't tried any lower spec machine with 7. As for your questions: 1. I guess some newer versions may not work at all with very old hardware. Not something I tested though. Look at the hardware release notes for minimum requirements. 2. Sorry, never tried it 3. Connect the hard disk to a newer machine, install there and transfer to the older one. There are good chances of success.

The whole Quad Core thing just didn't register. and what most unix users do. It is what a lot of unix users have done historically, but now that there is good support coming through for highly threaded, parallelized applications, developers are going to write more and users are going to run more applications that exploit that. It's not a Unix way versus Other OS Way thing -- its a response to the change in direction hardware development has taken over the past several years. Chip manufacturers have all but given up on the race to outdo each other on the MHz or GHz rating of their products. Nowadays it's all about how many CPU cores and how much cache RAM there is on each chip. 4 cores and 8MB is just the latest step in that evolutionary arms race. Try 7.0 instead -- it has all of the speed at multi-threaded, multi-core type stuff but has also regained the sort of performance levels you could so 4.11 is fastest? It depends very much on the application load you have to support and the sort of hardware you have available. For the sort of multicore chips that are all the rage nowadays, I'd go with 7.0 every time, even running single threaded applications.
