A pre-built package is built from the same ports system that you would use if you were compiling locally yourself. It's just someone else has done it for you. The thing to know is that in either situation, e.g. pre-built package or compile it yourself the ports tree is where the versioning and dependency tracking happens. There is more information in the Handbook, and probably presented better there than I can. It is spread out in several locations however. It may not be immediately apparent when reading the How to install software section that you also need to read the other sections further down that explain csup, portmaster, etc. The main thing we will keep reiterating though is the first step for updating installed apps is always refresh the ports tree first.

Since I don't use packages my vantage point is centered around compiling locally myself. However, most of what I describe applies to both situations. Typically the first thing to do is update/refresh the ports tree. Should you determine something needs to be updated the manual approach would be to change to the directory of the app in ports system and do make, followed by make deinstall, and then make reinstall. The deinstall/reinstall leaves your configurations for installed apps in place. Portupgrade is a tool that automates this. After refreshing the ports tree the portupgrade -a command will pretty much do what was described in the previous paragraph automagically. It isn't perfect and sometimes it hiccups. I've noticed that doing this more often so that only a few out of date apps need upgrading at any one time is smoother. It's when you have a hundred things that are really old and out of date because updating has been infrequent is when you are most likely to experience trouble. Hope this helps. I'm not the best at explaining things, but the Handbook is a most excellent resource to be studied extensively. It is written much better than anything I can manage.

after which /dev/mirror/gm0{,a,b} exist. However, even after

and that didn't help either.
I don't think sysinstall will do what you want.
However, what is your ultimate goal? To install a system with a gmirror
root drive? You can do that by installing direct to one of your drives
(ie ad0s1* or da0s1*) in the usual way and then converting the system
into a gmirror. The Onlamp article by Dru Lavigne is the best
referrence here:
http://onlamp.com/pub/a/bsd/2005/11/10/FreeBSD_Basics.html
Or else you can boot into the Fixit system, set up mirroring etc. and
then work through the rest of the installation process by hand. The
install sets are just split up tarballs and it's pretty easy to extract
a copy of a system from them.

Re: Upgrading packages - portupgrade confusion
Hi Jerry and Michael, thanks for all the advise and information!! I think I was confusing terminologies a little I was trying to imply that I have been building from ports all this time and *not* using pkg_add to obtain pre-built packages. I think mainly it's just that I've been using package managers too much with Linux and OpenSolaris distros that it got burned into my brain. not to mention that yesterday was a 14 hour shift without break which didn't help. The thing I don't quite understand though is that if the ports tree gets refreshed, do the packages get upgraded or will I need to rebuild them?? You have to rebuild them. Does this apply to ports too?? portupgrade -a or portmanager -u depending on what application you are using.

Yes - provided you had installed portupgrade and are using an up to date ports tree. If your ports tree is as old as the old version of nano then as far as FreeBSD is concerned it does not know of any new version. Refreshing your ports tree is where that information comes from. The utility of automation with portupgrade really comes into play when you are trying to update more than one port. One port at a time can be done manually as in the above example, but that quickly becomes tiresome when there are many. Sometimes a port may provide a shared library which many other ports depend upon. Updating that library may cause dependent apps to break. In such a situation portupgrade can recurse and rebuild all apps depending on that library so they will be linked against the new. Another tip: Whenever there are situations which can get sticky most of the time notes are placed into a file containing instructions on how to deal with the problem.

Don't expect too much accuracy from Keplerian orbits anywhere vaguely near Jupiter or Saturn - but yes they're a great place to start from. The software calculates the set of points of an ellipse based upon ephemeridal datas taken from the Minor Planet Cataloge. Again, so far, everything all right. The set of points of an orbit is all right and correct. But when it comes to positions at a specific time, then I loose hair! The program mentioned below can generate accurate results for as often as every few hours; handy at least for comparing your results over time. Compiling this piece of software with FreeBSD's gcc (V4.2) and clang (clang devel) on my private and lab's FreeBSD boxes (both most recent FreeBSD 8.1/amd64), this program does well, the calculated orbital positions are very close to professional applications or observational checks. But when compiling the sources with gcc44 or gcc45 (same source, same CFLAG setting, mostly no CFLAGS set), then there is a great discrepancy. Sometimes when plotting positions, the results plotted seconds before differs from the most recent. The ellipses are allways correct, but the position of a single point at a specific time isn't correct. Know the feeling; it took Kepler 20 years to get ellipses down pat :) I use the GNU autotools to build the package. I suspekt miscompilations in memory alloction or in some time- or mathematical functions like sin, cos. before I digg deeper I'd like to ask the community for some hints how to hunt down such a problem. regards, Oliver Sounds a cool project. I suspect you are miss-using a feature of C or are using uninitialised memory, and with gcc44/45's more aggressive optimisations it is getting it wrong. I have three suggestions 1) Use valgrind to check if it finds anything wrong when running your program. Check both the good and the bad builds. 2) If your program is made up of multiple C files, then try compiling all of the C files with gcc42, but just one at a time with gcc44. This way will help you track down exactly which C file has the bug. 3) Finally do some printf debugging to find the first line of code that is generating the wrong value. I hope these suggestions help. Andrew Hello Andrew. Thanks for your comments, they are worth trying out. I will do so ... item 2) oh, yes, a very good idea ... item 3) I did already, the whole software is built up by those printf's. The problem boiled down to be some problem in the UNIX time routines. I use localtime(3), time(3) and a strftime(3) and strptime(3). I use a 'wikipedia'-algorithm converting the actual time string into an 'epoch' used in astronomical calculations. Compiling this routine with gcc42 and clang everything is all right, compiling it with gcc44 or gcc45 it returns 10 times higher values. I use very 'primitive' cutoffs for casting a double value into an int - I need the integrale value, not the remainings after the decimal point. I will check this again and look forward for a cleaner solution. But isn't this a 'bug'? I'll try the BETA of the new FreeBSD PathScale compiler if I get some. Well, I'll report ... Please do. Well I can't help at all about the compilers, but I suggest having a close look over Steve Moshier's 'Numerical Integration of Sun, Moon and Planets' at http://www.moshier.net/ssystem.html I compiled the contents of http://www.moshier.net/de118i-2.zip as-is on a FreeBSD 5.5 system four years ago and it just ran, reproducing closely my late '90s results from the then DOS version SSYSTEM.EXE; there are #defines for using doubles or long doubles, major asteroids on not, even including 'your' asteroid's elements, and test results for comparison. You could check how your different compilers treat those sources? Apart from that it's very readable code and there's just about every maths and trig function imaginable, including quadrant-correct arctans and such. And also, of course, Julian Ephemeris Date handling routines .. not to mention close-to-JPL positions and velocities over many centuries :) Good luck. I'm hoping to revive and extend from my '90s Pascal astro programs in FPC soon to chew on 100s of years of ssystem ephemerides. HTH, Ian___ freebsd-questions@freebsd.org mailing list

The ports tree is just build instructions, so updating it doesn't update
any installed applications. It does let you use a program to see which
installed applications need to be updated, like pkg_version or
portversion.
Here's a document I've been working on lately about upgrading ports.
I'm not sure it's really there yet, but it covers the basics:
http://www.wonkity.com/~wblock/docs/html/portupgrade.html
Yep I kinda figured that before even posting and also I knew the
difference between packages built by pkg_add and compiling fresh from
ports since I've done a few BSD builds now but the really iffy thing was
a: communication - which let me down not explaining myself properly and
b: confusion of how to update

A port is just you doing the compiling locally yourself using the ports

This is really great advise as I'm kinda in the process of developing
documentation myself similar to Warren:
http://wiki.optiplex-networks.com/xwiki/bin/view/FreeBSD/
Luckily I build all my systems in jails so is easily managed and doesn't
blow up the whole system, however I do share the ports tree throughout
all jails and the base install meaning that things get simplified
although it can have its own problems such as version inconsistencies etc...
{{PS. this is also due to the fact that I only one available production
system and can't afford to get more although soon I hope to one day}}
Thanks so much guys and sorry for being so noobish these last 2 days,

Or is there any kind of live-stick-images out there, and if it is, how to move these on the stick (since windows is missing dd and nero doesn't like burning sticks :-) ) Thanks in advance Check my old message on how to do this in FreeBSD 7.2. The same instructions should work for 8.1 too, just change the version references. http://lists.freebsd.org/pipermail/freebsd-questions/2009-July/201928.html /Morgan On 2010-08-26 13:52, Friedemann Becker wrote: Thanks a lot, this seems to work. Is there any chance to get this into the faq or handbook? It's seems way more usefull to me than a live-CD. Best thing would be putting it into sysinstall, but maybe this is not reallistic. Best regards, Friedemann For the archives - below I've updated my installation guide to work with FreeBSD 8.1-RELEASE, GPT and ZFS if anyone finds it useful. Make sure your usb memory stick is empty and unpartitioned, then plug it in and boot from the FreeBSD DVD. Select your country and keyboard layout. Enter the Fixit environment and use the live filesystem on your DVD. Your usb memory stick will most likely be da0 but you can (and should) check it with camcontrol devlist before you continue. Create a new GPT partitioning scheme: # gpart create -s gpt da0 Create a 64KiB partition for the zfs bootcode starting at LBA 1920: # gpart add -b 1920 -s 128 -t freebsd-boot da0 Create a zfs partition spanning the remainder of the usb memory stick and give it a label we can refer to: # gpart add -t freebsd-zfs -l FreeBSDonUSB da0 (The starting LBA for the first partition is there to align the partitions to the flash memory's erase block size. This is particularly important for the main zfs partition. The main partition above will start at exactly 1MiB (LBA 2048) which will align it to any erase block size used today. This alignment is also of great importance if you use this guide to install FreeBSD to one of the newer harddrives using 4096 byte sectors.) Install the protective MBR to LBA 0 and the zfs bootcode to the first partition: # gpart bootcode -b /dist/boot/pmbr -p /dist/boot/gptzfsboot -i 1 da0 Create /boot/zfs (for zpool.cache) and load the zfs kernel modules: # mkdir /boot/zfs # kldload /dist/boot/kernel/opensolaris.ko # kldload /dist/boot/kernel/zfs.ko Create a zfs pool and set its bootfs property: # zpool create zrootusb /dev/gpt/FreeBSDonUSB # zpool set bootfs=zrootusb zrootusb Switch to fletcher4 checksums and turn off access time modifications: # zfs set checksum=fletcher4 zrootusb # zfs set atime=off zrootusb Extract at a minimum, base and the generic kernel: # cd /dist/8.1-RELEASE/base # DESTDIR=/zrootusb ./install.sh # cd ../kernels # DESTDIR=/zrootusb ./install.sh generic Delete the empty, default kernel directory and move the generic kernel into its place: # rmdir /zrootusb/boot/kernel # mv /zrootusb/boot/GENERIC /zrootusb/boot/kernel Make sure the zfs modules are loaded at boot: # echo 'zfs_load=YES' /zrootusb/boot/loader.conf # echo 'vfs.root.mountfrom=zfs:zrootusb' \ /zrootusb/boot/loader.conf Create /etc/rc.conf. Adjust and add to your own needs: # echo 'ifconfig_DEFAULT=DHCP' /zrootusb/etc/rc.conf # echo 'hostname=freebsd' /zrootusb/etc/rc.conf # echo 'keymap=swedish.iso' /zrootusb/etc/rc.conf # echo 'ntpdate_enable=YES' /zrootusb/etc/rc.conf # echo 'sshd_enable=YES' /zrootusb/etc/rc.conf # echo 'zfs_enable=YES' /zrootusb/etc/rc.conf Setup your time zone: # cp /zrootusb/usr/share/zoneinfo/Europe/Stockholm \ /zrootusb/etc/localtime Create an empty fstab to avoid startup warnings: # touch /zrootusb/etc/fstab Set the root password in the new environment: # cd # chroot /zrootusb /bin/sh # passwd root # exit Copy zpool.cache: # cp /boot/zfs/zpool.cache /zrootusb/boot/zfs Unmount the filesystem and set its mountpoint: # zfs unmount -a # zfs set mountpoint=legacy zrootusb Exit SYSINSTALL and reboot. You now have a fully functional and bootable FreeBSD installation on your usb memory stick.

Re: fsck reports errors on clean filesystem (mounted rw)

I ran fsck on my filesystems while system was running (partitons were mounted rw with moderate FS usage). fsck reported there were errors (INCORRECT BLOCK COUNT and others). I decided to reboot to single mode and check all filesystems. But in single mode fsck did not find any errors. 1. Can I be sure my filesystem is consistent? yes. 2. If fsck reports nonexistent errors (and probably will try to fix them if asked), isn't it even danger to run fsck on running system? They're not non-existant. and they're _not_ errors. they are *EXPECTED* inconsistancies in the _disk-based_ copies of the file-system meta-data because the 'current' (memory-resident) data is *not* written to disk at the instant the meta-data changes. It is a 'non-issue', because the O/S 'knows what it's doing There are exactly _four_ possible causes of file-system inconsistencies. 1) You can have an unexpected loss of power, where the CPU stops working before it as time to write the above-mentioned 'memory-resident' data to disk. There are sub-classes of tis event, to distinguish between A utility company outage, somebody accidentally 'pulling the plug', be it litterally, or the power on/off switch, and somebody itting the 'reset' button. They all ave te same effect, the processor can't get te 'current' data in memory out to the disk. 2) you can hve a catastropic O/S failure -- a system 'crash' -- were the O/S has discovered an internal inconsistency. _IT_ doesn't trust its own data enough to keep running, and takes 'the lesser of two evils' route of *not* writing known to be suspect data over the out-of-date data on the disk. 3) 'bit rot' on the phyiscal media itself. Where what gets read back is *not* what was written there earlier. Modern disk drives detect this inside the controller and use embedded ECC info to give the 'right' data back, while alerting that the problem exists. 4) Hardware failures of any of a variety of sorts -- flakey power supply, bad RAM memory, failing controller cipes, etc. Cause 1) can be virtually eliminated by 'good practices', and the use of a UPS with controlled automatic shutdown Cause 3) you can 'stay hread of' by monitoring system logs for 'corrected' errors on magnetic media. Causes 2) and 4) you can't do much about. With the exception of cause 3) -everything- leads to sysem crash which results in the 'preserved' data being inconsistent. The 'good news' is that you *know* it happened, and can run the fixit software (fsck) before letting users back on. ___ 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

Services do not start at boot
I have a FreeBSD 8.0-RELEASE installation with a UFS root and a ZFS pool for data and users. I have a couple of ports installed (netatalk, mediatomb) to share the content of the ZFS pool along with sharing it over NFS. After a fresh boot, the NFS shares do not work, mediatomb is not up and netatalk runs but does not share anything. There may be other things not working properly but those are the ones I notice. If I manually restart mountd, and the two ports using the rc.d scripts then everything works correctly until the next restart. I found this message in the archives which is similar to the problem I have except that I use dhcp: http://marc.info/?l=freebsd-questionsm=128354380615514w=2 After checking the log I see that indeed my problem is that these services start before the network is available and they don't cope well with that. As a fix, I added dhclient to the REQUIRE: for NETWORKING and a 'sleep 10' after the dhclient command in the dhclient startup script and made sure that background_dhclient is NO, and it still doesn't work. I am at a loss.

Re: sysinstall vs gmirror

I don't think sysinstall will do what you want. It certainly has been less than totally cooperative so far :( However, what is your ultimate goal? To install a system with a gmirror root drive? No, to install a system with each of /, /usr, and /var mirrored and journalled, with each journal kept in the same (mirrored) partition as its FS -- diagram below. IIUC, to put the journal in the same partition with the FS I have to create the journal while the FS is empty, hence before installing. (This is all UFS -- 512MB seems a bit small for ZFS.) The plan after partitioning the mirror is to create the journals, then install onto the journalled FS's, and finally to insert the second half of the mirror after everything else is up and running. ... you can boot into the Fixit system, set up mirroring etc. and then work through the rest of the installation process by hand. The install sets are just split up tarballs and it's pretty easy to extract a copy of a system from them. The part I don't know how to do is partitioning gm0 by hand. (I suppose it would require some sort of arcane incantations involving bsdlabel.) For all its limitations, sysinstall seems at least to know how to translate a reasonably human- readable representation of the desired slice and partition layout into the necessary fdisk and bsdlabel commands. Someone suggested using the PC-BSD installer, which knows how to do stuff like this, but when I asked how to do that from a memstick (rather than from a CD or DVD) I didn't get an answer. ad0s2 FreeBSD ad2s2 FreeBSD ad0s2a - gm0 - ad2s2a | +-+ | v gm0 gm0a gm0a.journal [gjournal label gm0a gm0a] rootFS gm0d gm0d.journal [gjournal label gm0a gm0a] /var gm0e gm0e.journal [gjournal label gm0a gm0a] /usr There's more to it than this, but I think I know how to do the rest. The current sticking point is getting the mirror partitioned. ___ 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: ipfw fwd and ipfw allow
per...@pluto.rain.com wrote: ... the 'fwd ... keep-state' statement does create a useful dynamic rule. It contradicts the ipfw(8) man page but works ... Hopefully someone who understands all this will submit a patch for the man page :) The man page says that the Dynamic rules will be checked at the first check-state, keep-state or limit occurrence, and the action performed upon a match will be the same as in the parent rule. It suggests that if the parent rule is a 'fwd' rule, the corresponding dynamic rule is also a 'fwd' rule, which would be no use (who needs a reflexive 'fwd' rule?). However, in reality a parent 'fwd' rule seems to create an 'allow' dynamic rule, which is useful but confusing.

I don't know of any exact howto, but the general principles are laid out here: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror It shows how to load geom modules from usb stick, once they are loaded you can then setup geom, Next fdisk/gpart accordingly(don't forget to make it bootable). If your setup if GPT compatible, I recommend using it. IMO, it's significantly more straightforward than the old mbr style. once you've got your partitions setup the way you want, create your filesystems and use the instrustions on the page to extract the distrobution on to them. Obviously they need to be mounted for this to occur, so adapt the example to your own use. Note, I've never tried to boot from a gjournaled geom, but I think it will work. -- 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
