cpu utilization question in FreeBSD
Hi, Im trying to put together a number of data recorders, to collect raw data from kernel or from applications. Here you can see a basic idea of SDR: http://www.systemdatarecorder.org/recording/recdesign.html http://www.systemdatarecorder.org/recording/recorders.html Im currently trying to port sysrec, http://www.systemdatarecorder.org/recording/sdr_bin/sysrec to FreeBSD. I would like to understand how CPU Utilization in FreeBSD counts, comparing to Solaris. Currently sysrec records the following metrics: # Utilisation, # CPU# usr + sys time across all CPUs # Memory # free RAM. freemem from availrmem # Disk # %busy. r+w times across all Disks # Network# throughput. r+w bytes across all NICs # # Saturation, # CPU# threads on the run queue # Memory # scan rate of the page scanner # Disk # operations on the wait queue # Network# errors due to buffer saturation # Would be fair to count CPU Util in FreeBSD similar with Solaris, User + System time ? Is there any Perl module or KSTAT functionality which exports these functionalities to userland for simple consumption ?

I have one port, namely /usr/ports/www/pound that needs the version of

Personally, I've been using the ports version of openssl on a number of
machines, and I haven't run into the sort of problems you claim. There
is not a lot between the ports of the base system, especially if you're
running a recent version of FreeBSD -- it's another port to manage, but
you get access to various bits of new functionality.
Is there a configuration somewhere that could be used to say that
no-one except pound should use openssl from the ports?
The only way I see is to put includes and libarries of openssl in some
obscure place and have pound point to them.
OK, this /should/ work. Add the following to /etc/make.conf:
WITH_OPENSSL_BASE= yes
.if ${.CURDIR:M*/www/pound}
WITH_OPENSSL_PORT= yes
.endif
Test SSL-using executables with ldd(1) to see which copy of libcrypto they
link against.

Backup and FreeBSD/ZFS
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm currently considering switching my Backend (Running WSS2008 Enterprise) to FreeBSD RELENG_8+zfs, however my last melee with ZFS and backups to Autoloader (HP 1/8 G2 LTO-3 job) didn't quite turn out in my favour. Seems FreeBSD has a decent backup solution for UFS/2 (dump/restore) but such luxuries where nowhere to be found for ZFS (but the performance was quite good!). So, my question is this: Can someone point me to the proper place to start reading on getting RELENG_8+zfs backed up to tape robotics (or more specifically: LTO-3 with a HP autoloader)? Will going the Opensolaris route be easier? (I had hoped to be able to use net/istgt/ from ports, but I guess I could find a different solution to that problem in Solaris). Any pointers would really help me here.

.if ${.CURDIR:M*/www/pound}
WITH_OPENSSL_PORT= yes

No, it won't -- at least, if you leave it in make.conf after building
www/pound, it wil break all subsequent rebuilds of all other ports
that depend upon the base system openssl. Matthew, you ought to know
better ...
From bsd.openssl.mk:
.if defined(WITH_OPENSSL_BASE)
...
.if exists(${LOCALBASE}/lib/libcrypto.so)
check-depends::
@${ECHO_CMD} Dependency error: this port wants the OpenSSL
library from the FreeBSD
@${ECHO_CMD} base system. You can't build against it, while a newer
@${ECHO_CMD} version is installed by a port.
@${ECHO_CMD} Please deinstall the port or undefine WITH_OPENSSL_BASE.
@${FALSE}
.endif
Mixing and matching the different openssl versions can lead to
problems (for one thing, there are too many sloppy
LDFLAGS=-L${LOCALBASE}/lib floating around in different ports), and
you'll have to hack port Makefiles and use ldd(1) or other tools to
verify that your changes work. You're probably better off just using
one or the other. If you still want to try it, then I suggest
installing security/openssl in non-default PREFIX, then patching the
www/pound Makefile so that it doesn't use USE_OPENSSL, and then adding
whatever variables are needed by it's configure script to locate and
link with security/openssl to CONFIGURE_ENV and/or MAKE_ENV, as well
as the proper LIB_DEPENDS on security/openssl. After doing this and
installing www/pound, if rtld(1) is still loading the base system
openssl when www/pound binaries are executed, or can't find the
security/openssl libraries off in their non-default location, then use
libmap.conf(5) to point (only) the www/pound binaries to the
security/openssl libraries. You'll have to ensure that your changes
to www/pound's Makefile aren't wiped out by subsequent updates to your
Ports tree, of course.

Helps! Installation hangs for FreeBSD 4.x and 5.1
Dear All, I have encountered in installing FreeBSD including version 4.3, 4.5, 4.6, 4.8 and 5.1 on my new Dell laptop. Here is some info about the laptop. It came with Vista Home Basic. I have formatted the hard drive and installed XP on it. While doing so, I change the SATA option from AHCI to ATA, which may cause my following problem. When I tried to install various version of FreeBSD, installation hangs at different points. For 4.3 and 4.5, installation hangs at following line: *ppc0: parallel port not found* For 4.6 and 4.8, installation hangs at following line: *ata1-slave: ATAPI identify retries exceeded* For 5.1, installation printed out something like: *:/ write failed, filesystem is full panic: Going nowhere without my init! syncing disks, buffer remaining ... 454 454 290 290 290 giving up on 125 buffers* I have never encountered such problem since I have been playing with 4.3 for a while on other older computers.

John W wrote: I updated my ports tree with csup, and tried to run 'portmaster -na'. It gave me this: === The mail/p5-Email-Simple-Creator port has been deleted: Folded into p5-Email-Simple package Ok, that makes sense. But what do I do to fix it? It seems I need to replace dependencies on p5-Email-Simple-Creator with dependencies on p5-Email-Simple. But if I manually do that, won't my changes be blown away the next time I update ports? The committer who added the entry to /usr/ports/MOVED also seems to have adjusted any dependencies in the Ports tree, back on 24 Nov. 2009. So if you have an up-to-date ports tree, then after rebuilding the ports that used to depend upon p5-Email-Simple-Creator, those ports will depend instead upon p5-Email-Simple, and no further intervention will be needed. Perhaps I should use the '-o' (origin) option of portmaster? I'm not 100% sure what that does, incidentally (explanation welcome). I assume something like: portmaster -o p5-Email-Simple p5-Email-Simple-Creator I don't use portmaster often, but I think it should instead be: portmaster -o mail/p5-Email-Simple p5-Email-Simple-Creator Read the portmaster(1) manpage carefully, and look at the examples. Will those changes get blown away by the next update of ports? In this case, no. Is the most correct solution just to wait until all maintainers of ports which depend on p5-Email-Simple-Creator each update their makefiles to depend on p5-Email-Simple, instead? (Though that doesn't help in the short term :) That should already have been done. In other cases, if it has not, then you should send a message to the committer who made the change (if you aren't familiar with cvs(1), which is used to manage the ports repository, then you can use cvsweb.freebsd.org or www.freshports.org to find this information), and to the maintainers of the ports that have the outdated dependencies. If they don't respond within a reasonable amount of time, then file a Problem Report: http://www.freebsd.org/support/bugreports.html While they are fixing the problems, you can patch the dependent ports yourself (this is sometimes as simple as changing the *_DEPENDS line in the port Makefile; other times, it requires patches to the port sources), and then rebuild the ports; or you can try to use portmaster -o , or portupgrade -o, which will succeed in the simplest cases. You could also do it manually, by using sed(1) to substitute every occurrence of the old PKGNAME with the new PKGNAME in the @pkgdep lines in /var/db/pkg/*/+COMMENTS, and likewise for the PKGORIGIN values preceded by DEPORIGIN.

In fact, it doesn't work at all -- pound gets linked against the base

But, generally you cannot run fdisk on a disk that is in use on a running system - which generally means that it is the boot device, has filesystems mounted or has part of the currently designated swap space. You will need to plug in a boot cd or bring up the fixit system for that. The fixit system runs from memory - creates filesystems and mount points in memory rather than on disk, so it can talk to any disk. New, if you are working on a non-used (extra) disk, eg one that is not the boot device nor has any mounted filesystems or swap space on it, then you should be able to fdisk and bsdlabel that from a running system.

Thanks very much, Bill No. FreeBSD can run many Linux applications under emulation (and possibly some Sco applications, but that code branch has rotted due to disuse). It can't run Mac OS X applications though. Despite certain similarities between FreeBSD and the unix underpinnings of Mac OS X (darwin) i's not possible to run even a command-line program from Mac OS X on a FreeBSD box. Not that that's a particularly interesting thing to do. Obviously what you want to run are all those nice graphical apps written in cocoa and whaterver else is flavour of the month at Apple. There is simply *no* chance of that: the graphical environment is Apples' proprietary code, and they aren't going to be releasing it any time soon. Without the graphical layers, trying to get a Mac application running is an exercise in futility. Why don't you explain what exactly you're trying to achieve: free alternatives to most Mac applications are generally available. They won't be anything like as slick, and functionality will only be approximately the same, but they might do.

The fixit system runs from memory - creates filesystems and mount points in memory rather than on disk, so it can talk to any disk. New, if you are working on a non-used (extra) disk, eg one that is not the boot device nor has any mounted filesystems or swap space on it, then you should be able to fdisk and bsdlabel that from a running system.

Basically, as far as I can tell, on a running system, there is no combination of keystrokes in sysinstall's label editor that will create an ad[1-9]s1a, except the 'a' key which produces a 512M s1a. All other keystrokes (namely 'c') go straight to ad[1-9]s1d when a second disk is placed in a system booted from ad0s1a.

I've never seen disks spontaneously changing from ad0 to ad4. I have seen motherboards where toggling BIOS settings to do with PATA compatibility / SATA support changes the device number. Sata drives frequently appear as ad4 and ad6 -- that's because each SATA connector is behaving like a separate IDE bus (with 2 devices -- master and slave -- allocated per bus, even though you'ld only ever use one with SATA disks). Devices ad0 -- ad3 are allocated to the *real* IDE busses on the motherboard -- probably one of those slots is taken up by a CD or DVD drive. Now, with some mobo's ad4 and ad6 is all you're going to get. Others, you can tweak some settings in the BIOS and your SATA drives will then appear as ad0 and ad1. Unfortunately it's pot luck as to what kit this works with, and what it doesn't.

This gets you what is referred to as a dangerously dedicated disk in the documentation.If you are doing nothing unusual with other OSen, then it works fine.But, it is also not at all hard to use fdisk and bsdlabel to create the full slice+partition.

If the disk will not be bootable take out the 'B' from each of the fdisk and bsdlabel commands. You probably do not need the two dd-s, but sometimes they are needed if the system cannot read the sector 0 on the disk for some reason. Finally, when that is done, do: newfs /dev/ad1s1d Make yourself a mount point and mount the new disk. mkdir /bigwork mount /dev/ad1s1d /bigwork Edit /etc/fstab so it will mount automatically. It is not weird or mysterious, though I admit the man pages for both fdisk and bsdlabel could stand a going through.

The three main reasons are: Backups.It is often easier to manage backups when the disk storage is thoughtfully divided into reasonable and functional pieces. Emergencies. If your system crashes, especially if it is due to some disk problem, you may need to boot your system to single user. In that case you will start with only / (root) mounted as read-only. Having a fairly small root partition means the chance of having the bad disk area be in what you are trying to mount is reduced (not eliminated, of course). Anyway, you may be more able to get up to a minimal system and then work on recovering the other partitions. Boot time. A possible benefit is that only root needs to be fsck-ed before other things can start. Remaining fsck-s can run in parallel. This will take you less time to get back up after an abnormal shutdown - such as from a sudden power loss. The 'other' system has 7.2 and has devolved to a 25% chance of a hard freeze every time I unplug a ucom device (seems to have cropped up between 7.2-release and 7.2-stable#3). 8 likes usb, so I like 8.

IPv6: rtsol must be run a second time after boot to pick up default route
I recently set up an HE.net tunnel using the following guides: http://www.freebsd.org/doc/handbook/network-ipv6.html http://www.freebsddiary.org/ipv6.php FreeBSD 7.2-p5 is used for the router and the host, and it works beautifully, except that the host will only pick up the IPv6 prefix on boot and set its IP accordingly (local network functions), but will NOT set the default route unless I wait up to 10 minutes for the advertisement, or manually run rtsol. The same problem happens with OS X 10.6.2, but not with Win7 (and Linux 2.6 remains untested at this time). The host has no firewall running currently, and there's no firewalling between the router and the host. Running rtsol with debugging doesn't show anything out of the ordinary, either during boot or after. Rtadvd is running on the router and my setup is identical to the guides other than device name: $ cat /etc/rtadvd.conf vr1:\ :addrs#1:addr=2001:470:::::prefixlen#64:tc=ether: Any suggestions? I've tried a few variations of rtadvd.conf without any changes in behavior. I'm inclined to think it's router-related, given the issue on multiple OSes, but I suppose it could go either way.

More sysinstall questions 1 of 2
Yesterday, I asked how sysinstall mounts the drive on which FreeBSD is to install. I might not have been clear enough so I will try again since my question may have been confusing. The system is booting via mfs so we are starting out with a virtual disk drive made of memory. The hard drive is sitting right there as /dev/ad0. It can be formatted and mounted and appears to be working properly. As a trouble-shooting step, I ran sysinstall from mfs manually exactly as I have done from a CDROM on that very box. With the mfs system, sysinstall sees the hard drive and appears to let you format it. The bsdlabel section appears to let you assign the partitions. One selects distributions and a ftp site and then . . . it all goes wrong. The commit does not format the disk. There is no last chance prompt. It goes right to the download and proceeds to install FreeBSD all over mfs. The CDROM for installing FreeBSD correctly formats the drive and installs the OS on that very same box. My first question is why doesn't the mfs do the same thing? My second question will be on a separate message.

I mean, I know I should quit being a %^# and read the manpage for bsdlabel, but sysintall really does have a nice tui. 'C'reate slice goes straight to 'd', even on a 'fresh' disk. sysinstall (or sade) will assign 'd' to the first partition if its mount point for the partition is not specified as '/'. This is usually right, when partitioning either another slice on the same disk, or a slice on another disk, where '/' is already assigned to the booted disk. In the case of what you're doing, ie preparing another disk to copy your system to, it's not hard to fix that later with bsdlabel -e, as Jerry has pointed out, and which I'll detail further below. I see in the handbook, this is alluded to, but some intermediate level between begginer and expert (bsdlabel just strikes me as way too easy to trash the disk I'm running off of while trying to make a backup), would be nice...512M just won't fit the kernel+symbols. A default 1GB '/' is on the cards, perhaps by 8.1, but in any case I've never used anything like the autodefaults for other partitions either. bsdlabel(8) is not so scary. For one thing, anything you do is shown but not committed to disk if you use the -n switch. Try it. Also, the man has examples of saving and restoring an existing label, so if you: # bsdlabel ad1s1 saved.ad1s1.label then if you stuff it up you can later on just restore it with: # bsdlabel -R ad1s1 saved.ad1s1.label fuming, reading man bsdlabel ;) Well, Create slice would be an fdisk(8) thing, not bsdlabel. bsdlabel creates partitions within a slice. But, generally you cannot run fdisk on a disk that is in use on a running system - which generally means that it is the boot device, has filesystems mounted or has part of the currently designated swap space. You will need to plug in a boot cd or bring up the fixit system for that. The fixit system runs from memory - creates filesystems and mount points in memory rather than on disk, so it can talk to any disk. If you set kern.geom.debugflags=16 and 'w'rite from either sysinstall's fdisk or bsdlabel screens you can update the partition table or your new slice's bsdlabel, but you have to be very careful, and in the case of fdisk, you need to reboot before labeling the new slice. Certainly using a fixit boot is the safe and sure way to avoid complications. New, if you are working on a non-used (extra) disk, eg one that is not the boot device nor has any mounted filesystems or swap space on it, then you should be able to fdisk and bsdlabel that from a running system. This seems to be Steve's case, but he's right; it will start creating new partitions as 'd' rather than 'a' (since there's already a '/') unless he boots into either sysinstall or fixit from another source. I have no idea what you mean by 'C'reate slice goes straight to 'd' It does not match anything I remember being possible. I don't happen to have any system handy at the moment that I can muck with disks on. jerry I've several times added partitions to extra slice/s on either the boot disk or added disks (including sliced USB flash disks) using sysinstall invoked from the running system, and these do start with 'd' partition. Ok, terminology crash. As someone pointed out, I'm talking about label, here, not fdisk, and partitions, not slices (had those two backwards in my head). Basically, as far as I can tell, on a running system, there is no combination of keystrokes in sysinstall's label editor that will create an ad[1-9]s1a, except the 'a' key which produces a 512M s1a. The 'a' key auto-assigns '/' as the mount point for partition 'a', which is why you see that. You wouldn't be able to commit that anyway, as /, /var, /usr would conflict with your already mounted slice, and newfs'ing your existing system is most likely not what you want :) All other keystrokes (namely 'c') go straight to ad[1-9]s1d when a second disk is placed in a system booted from ad0s1a. I'm just trying to make a fresh disk ready for dump/restore with a 1G /, so I guess sysinstall is out as an option at this time. You may be better off just installing the new system onto ad1 straight up, ignoring your ad0, when you can just use sysinstall. However .. sysinstall (or sade) run from an existing system is a pretty convenient way to partition a disk, or slice. You don't really need to worry about it starting at 'd', as you can easily correct that later. Eg this one: smithi on sola% fdisk -s ad0 /dev/ad0: 77520 cyl 16 hd 63 sec PartStartSize Type Flags 1: 30240
