switching timezone within crontab?
Hey, So, we have systems running in Eastern and Pacific time zones as their local time, not to mention DST. So, we like to schedule a few things with UTC to save our sanity. If a system is not running UTC as its locale, but I want to schedule a UTC cron job in crontab, is it sufficient to put a little: TZ=UTC Right before the job? I will of course discover this by trial-and-error, but it is nicer to hear from someone who has wrestled with this before. :) http://widell.fulhack.nu/bd/dst/ is fun, but dated.

Re: Carp and Apache
Dave,
Yes.
The trick with CARP is that it is an IP-level heartbeat, so if you are
running Apache, you want to carp up after you start apache, and carp
down before you stop Apache.
From some test boxes, web0:
ifconfig_fxp1=inet 192.168.1.210 netmask 255.255.255.0
defaultrouter=192.168.1.1
cloned_interfaces=carp0 carp1
Then, web0 application config file:
export CARP_PASS=mekmitasdigoat
# MASTER
export CARP_carp0_IP=192.168.1.206
export CARP_carp0_VHID=1
# SLAVE
export CARP_carp1_IP=192.168.1.207
export CARP_carp1_VHID=2
export CARP_carp1_SKEW=100
Next, the Application control script:
# CARP
carp_ifs=`ifconfig -l | tr ' ' '\n' | grep carp`
# Set up CARP
for carp_if in $carp_ifs; do
eval carp_ip=\$CARP_${carp_if}_IP
eval carp_vhid=\$CARP_${carp_if}_VHID
eval carp_skew=\$CARP_${carp_if}_SKEW
if [ -n $carp_vhid ]; then
carp_vhid=vhid $carp_vhid
fi
if [ -n $carp_skew ]; then
carp_skew=advskew $carp_skew
fi
if [ -n ${carp_ip} -a -n ${carp_vhid} ]; then
ifconfig $carp_if pass $CARP_PASS $carp_vhid $carp_skew
$carp_ip
ifconfig $carp_if down
else
echo WARNING: $carp_if but missing CARP_${carp_if}_IP or
CARP_${carp_if}_VHID!
fi
done
[... later ...]
if [ $status -eq 0 ]; then
echo Apache successfully ${cmd}ed
echo Ready to CARP UP!
if [ -n ${carp_ifs} ]; then
for carp_if in $carp_ifs; do
eval carp_ip=\$CARP_${carp_if}_IP
eval carp_vhid=\$CARP_${carp_if}_VHID
if [ -n ${carp_ip} -a -n ${carp_vhid} ]; then
ifconfig $carp_if up
fi
done
sysctl net.inet.carp.preempt=1
fi
else
echo Apache failed to $cmd
exit 2
fi
Okay, so that's really quite a mess, but basically:
* Set cloned_interfaces in rc.conf to create carpn at boot.
* One IP alias and VHID per CARP IP.
* Set up the backup server with higher advskew.
* For availability, teach you apachectl script to ifconfig the carp
interfaces, ifconfig down, start apache, ifconfig up, and ifconfig
down before stopping / restarting apache.

Reccomendations for FC-attached storage appliance?
[NOTE: cross-posting to freebsd-scsi and -questions ... please reply direct to me, or followup to just ONE list. I may post summary after.] Hello, I have spent the past few weeks confusing around with different vendors to find a cool external disk solution that might offer high performance, and high availability for our production database. My questio is two-fold: 1) Would anyone like to share a preferred storage solution? My dream is something where I can connect two FC controllers to two FreeBSD servers. If one controller fails, or if one server fails, I can still mount the same disks via the redundant server or controller. It sounds like most solutions have the disks on one controller or the other, so if a controller fails, the disks are inaccessible until you swap out the failed controller. The Applex Xserve RAID comes to mind. 2) Would anyone like to share a preferred HBA? I am constantly frustrated by suggested solutions because it seems that every disk appliance only ever supports one HBA. For example, the Apple ... only supports LSI7202XP. My research has found zero evidence that this is supported by FreeBSD. So, if that wont work, I should just run Linux? Or has someone stress-tested their favorite HBA and found it to be totally robust in some configuration ... ? Thanks a bunch!

Fibre Channel disks to two Systems?
[NOTE: If posting followup, please mind the cross-post to -questions and -scsi.] Hello, We host our PostgreSQL database on FreeBSD. Until now, we have just built the beefiest DB server we can spec, and then dump the data every thirty minutes to a backup DB server, so if the primary DB server fails, we load the database on the backup and fail over to the backup server. But I'd rather offload the disk to an external storage device, then I can have two identical DB servers, and if one fails, I swap the disks over to the other DB server, mount the filesystem, possibly run data consistency checks, and proceed from there. From my research, I am thus far most impressed with the SANbloc 2Gb, which holds fourteen FC drives in a 3U rackmount. It can be had with redundant RAID controllers, or as a JBOD. There are similar products from other vendors as well. I could concievably do the RAID in software by running a gstripe across a set of gmirrors. As I understand it, I can have an FC loop with one or more drives, connected to two servers, and either server can talk to one or the other drives exclusively. My QUESTION is: how is the arbitration done in FreeBSD? You run camcontrol on either server and activate / deactivate drives in the loop? What happens if say, the primary server locks up in some weird manner? Can it block the backup server from talking to the drives? (We can always have a NOC tech turn off a badly failed primary database, and power-cycle the disk array, if needed ...) A really far-out idea I had was that with fourteen drive bays I could have two hot spares, and then set up a stripe across four mirrored pairs (4x2 = 8-disk RAID10) and then with the remaining four drives assign each to be a third component of the gmirrored pairs, let the gmirrors sync up, then detach those drives from the gmirrors, mount them on the backup database, gstripe those containers together, and have a point-in-time snapshot of the drive array that could be mounted on the backup server, from which I could run database dumps, or conduct failover tests, etc. (I could kick this around -geom. :) Uhmmm, has anyone done similar? Suggestions? Feedback? Advice? Or, should I try to get a NetApp, or similar device, even though FreeBSD does not support iSCSI, because NFS performance over GigE may still beat FC? Also, does anyone have a FreeBSD-friendly storage systems integrator or other vendor they can reccomend, particularly one near the San Francisco area? I keep contacting various vendors who then fail to get back to me. :( Thanks for all feedback and suggestions!

Re: dump(8), incremental backups, Tower of Hanoi sequence, don't get it
On Wed, Aug 24, 2005 at 12:32:38PM +0100, Scott Mitchell wrote: Another useful rsync option is --link-dest: --link-dest=DIR This option behaves like --copy-dest, but unchanged files are hard linked from DIR to the destination directory. The files must be identical in all preserved attributes (e.g. permissions, possibly ownership) in order for the files to be linked together. I use this to rsync each backup into a new directory on the backup volume, named for the date of the backup. The result is a directory for each backup run, apparently containing every file from the source tree - but most of them are just hard links to some previous backup. This saves a *lot* of disk space as you only ever copy files that have changed since the last backup. You also have the complete file tree for each backup, so it's trivial to restore the version of a file that existed on any particular date. All this great discussion got me researchinng. I haven't tried this out but it looks like rsnapshot integrates a lot of features like this into a single configurable, cronable script. It is in ports as well. A lot of systems make use of cp -al ... well, for us FreeBSD people that means gcp from coreutils. rsnapshot looks like a lightweight, OS/FS-portable method of building rotating filesystem-wide snapshots via hardlinks, but can be made to operate on limited sets of directories, etc. It can create local snaphots of remote directories, but not, apparently, remote copies of local directories. One trick I gleaned from http://burd.info/gary/2003/03/snapshot-backup-using-rsync-and-ssh.html is to invoke rsync with --rsync-path which points to a script which performs maintenence functions and then passes off to rsync proper, so you could probably set up a client-triggered rsnapshot configuration if you were, say, doing backups of a Windows laptop client. :) -danny -- http://dannyman.toldme.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Ilari, Three suggestions: 1) Use gmirror to mirror the hard drives, instead of manually mirroring them. 2) If all you have to deal with are static files and a not-super-giant-filesystem, use rsync. rsync -avz --delete once a night will mirror your data between drives or between machines without any trouble. The only disadvantage is there is no file retention if you want to restore a corrupt / deleted file after the fact. Maybe you could rsync between the USB disks prior to rsyncing your backups, then you have two iterations of data ... 3) Look into using AMANDA, which I think can be run without a tape device, if it regards your disks as long-term holding disks. It is probably overkill for you, but at least then you get to learn a more powerful backup package which you might want to have experience with for the future, and you won't have to worry about Towers of Hanoi or anything because AMANDA is smart enough to figure this out itself. Though, honestly, probably all that you need is to do 0 1 1 1 or such. Or possibly, mount filesystem snapshots and if you get acceptible performance just dump level 0 every night. Or ... really it depends what you want and what you've got. Do you want to be able to restore deleted files from the week prior?

How are you giving anything different arguments? I only see one service

So how do I use the same script to run 2 instance of memcached?
So, you have memcached1.sh :
#!/bin/sh
#
# PROVIDE: memcached1
# REQUIRE: NETWORKING
#
# Add the following lines to /etc/rc.conf to run memcached:
#
# memcached1_enable=YES
# memcached1_flags=
#
. /etc/rc.subr
name=memcached1
rcvar=`set_rcvar`
command=/usr/local/bin/memcached
command_args=-du nobody ${memcached1_flags}
load_rc_config $name
run_rc_command $1
And then you have memcached2.sh :
#!/bin/sh
#
# PROVIDE: memcached2
# REQUIRE: NETWORKING
#
# Add the following lines to /etc/rc.conf to run memcached:
#
# memcached2_enable=YES
# memcached2_flags=

. /etc/rc.subr
name=memcached2
rcvar=`set_rcvar`
command=/usr/local/bin/memcached
command_args=-du nobody ${memcached2_flags}
load_rc_config $name
run_rc_command $1
And you set memcached1_flags and memcached2_flags in rc.conf where you
were setting memcache_flags formerly.
However, unless you really know what you are doing, if you are trying to
run TWO memchached instances, I'd suspect, as another has asserted, that
your understanding of memcached is flawed. I'd check with the memcached
community to see if there isn't a better way to get things done in the
first place.

FWIW, it looks like you are doing the right thing. Maybe you have hit a

There may be a tweak for dhclient's configuration to extend the amount
of time it will attempt a profile before giving up and trying the next.
I would like to think that mode 11g is superflous, and that you can
just set that before-hand, or at a lower level ...

I much prefer hardware implementation than software. True hardware RAID frees up a lot of CPU time if you have heavy IO and software just can't keep up if you utilize CPU intensive apps. When you have a dual Xeon setup, you are more likely to be bound by disk than CPU. And a RAID that you can not monitor is a BAD RAID. The biggest thing that bothers me about my current environment is that I have remotely-deployed machines with RAIDs and I can't tell when a disk goes bad unless I visit the datacenter. Last time I was there I had a RAID card throwing an audible alarm, even though nothing was wrong. I had to reboot a critical system to fix that. If you can implement it in software, then its worth the headaches you'll avoid with hardware dependencies. If you're concerned at CPU overhead, spend the cash you would have spent on a RAID card and upgrade your CPU.

(LONG) ATA Benchmark: 5.x Reads Slower than Writes
Hello, BACKGROUND I need to purchase a new system for our developers, for use as a Postgres database test server. Having a RAID, probably RAID1, is desirable for performance and reliability. I have recently set up a system with a gmirror-based software RAID1 on a pair of 250GB ATA drives. I would like to stick with gmirror, because: - We save money on extra hardware. - Since gmirror is part of FreeBSD, maintenance is a lot easier than with a hardware solution. SUMMARY But before I go balls out, I should see how well it compares to hardware RAID. So, I do some benchmarks with bonnie++. Since this simulates create, write and read on thousands of random files, this sounds like a good approximation of what Postgres does. :) I don't have the time and hardware to do very scientific tests, but I have been able to run a series of benchmarks using bonnie++ on some systems I have available to me. The ATA-based gmirror performs extremely well, compared to a few Adaptec RAIDs that we have, EXCEPT that the sequential and random reads are MUCH SLOWER than the hardware solution, and even *slower than the preceding write operations*. This is counter-intuitive, especially since RAID1 implies slowed writes and faster reads. I tried the benchmark on my workstation (single 2.5 IDE in a laptop) and got comparable write-faster-than-read results. DATA I was able to make use of the following test systems. I ran tests in multi-user, but tried to favor times when there wasn't much background activity: mito: (lone 2.5 ATA) 5.4-PRERELEASE CPU: Intel(R) Pentium(R) M processor 1.50GHz (1495.16-MHz 686-class CPU) atapci0: Intel ICH4 UDMA100 controller ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 ad0: 28615MB TOSHIBA MK3021GAS/GA129D [58140/16/63] at ata0-master UDMA100 amun: (gmirror RAID1 2 x WD250GB High Intensity) FreeBSD 5.3-RELEASE CPU: Intel(R) Xeon(TM) CPU 2.80GHz (2799.22-MHz 686-class CPU) atapci0: SiI 3112 SATA150 controller ata2: channel #0 on atapci0 ata3: channel #1 on atapci0 ad4: 238475MB WDC WD2500SD-01KCB0/08.02D08 [484521/16/63] at ata2-master SATA150 ad6: 238475MB WDC WD2500SD-01KCB0/08.02D08 [484521/16/63] at ata3-master SATA150 atapci1: SiI 3112 SATA150 controller acd0: CDROM CD-224E/1.9A at ata1-master UDMA33 janus: (Adaptec RAID1 2 x 72G 10,000 RPM SCSI) FreeBSD 4.10-STABLE CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2399.33-MHz 686-class CPU) [DUAL] aac0: Adaptec SCSI RAID 2120S mem 0xf800-0xfbff irq 16 at device 1.0 on pci2 aac0: i960RX 100MHz, 48MB cache memory, optional battery present aac0: Kernel 4.0-0, Build 6011, S/N baec64 aac0: Supported Options=1f7eCLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,WINDOW4GB,SOFTERR,NORECOND,SGMAP64,ALARM,NONDASD aacd0: RAID 1 (Mirror) on aac0 aacd0: 69998MB (143357184 sectors) db2: (Adaptec RAID10 4 x 36G 15,000 RPM SCSI) FreeBSD 4.8-STABLE CPU: Intel(R) Xeon(TM) CPU 3.06GHz (3065.81-MHz 686-class CPU) [DUAL] aac0: Adaptec SCSI RAID 2120S mem 0xf800-0xfbff irq 18 at device 2.0 on pci5 aac0: i960RX 100MHz, 48MB cache memory, optional battery present aac0: Kernel 4.0-0, Build 6008, S/N b97ce8 aac0: Supported Options=1f7eCLUSTERS,WCACHE,DATA64,HOSTTIME,RAID50,WINDOW4GB,SOFTERR,NORECOND,SGMAP64,ALARM,NONDASD aacp0: SCSI Passthrough Bus on aac0 The raw data can be viewed at http://dannyman.toldme.com/scratch/benchmarks/ ANALYSIS Unfortunately, my hardware RAIDs are on FreeBSD 4, and gmirror is on 5.

Re: Securely allowing just one application via telnet
Anthony, Securely and telnet is an oxymoron. This is mainly because any data, including passwords, sent through a non-encrypted connection, can be sniffed by anyone who can access any of the intervening networks. Your question is really very open-ended and vague. The correct question may be I need to facilitate FOO. and then go about solving that. When you ask I need to do something with telnet, I am inclined to say I bet you are asking the wrong question. One (easier) way is to use a traditional login shell and set the config file to pass execution to your application. For example, if the user is set to use csh, you can put exec fooprog in his .login. An advantage of this is that you can set environment variables and stuff before handing execution to this application. If you do this, and you can not trust your user (he's using telnet, so his password is easy to steal,) then you want to look at how your development system handles signals. You don't want him sending some clever signal to your system that lets them sneak out in to something else. That said, if you set a user's shell (See /etc/master.passwd and the excellent pw program,) to your executable, then that is the program that will be executed as the user's login shell. (I once set up a user on my system to launch freeciv on the remote terminal so some friends and I could play this game in my dorm laboratory from the workstation in my dorm room. I think I just set the shell init file to exec freeciv and disabled the user when we weren't playing games. :) Another way is to put the program in inetd.conf ... you just telnet to some port, and things happen. This is like putting the program in as the user shell, but there are fewer insecure layers (telnet tends to have security advisories crop up) but you wont have telnet asking for a password for you. Anyway, good luck.

Re: Digital Cameras

Hello, I second this suggestion! Get a USB media adaptor, plug it in, the device should pop right up, then you use the mount command and add it like a disk drive, copy your photos, clean up the disk, unmount, and you are done!

(Though, Flickr is a lot like online Picasa but you have to pay a yearly subscription fee, and the photo manipulation stuff depends on Flash plugin, so, for now, you need Windows to rotate your uploaded images ) Cheers, -danny -- http://dannyman.toldme.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
FAQ: How to Measure Swap in FreeBSD
Hello, I tried to get an answer to this question last year but failed. Today, I think I have it. Q: How do you measure swap utilization in FreeBSD? (Assuming you are writing a script to gather performance metrics.) A: If you are writing a C program, check kvm_getswapinfo(3) and maybe take a gander at the bottom of /usr/src/usr.bin/top/machine.c. A: If you are writing a Perl script: Measure swap activity: sysctl vm.stats.vm.v_swapin vm.stats.vm.v_swapout vm.stats.vm.v_swappgsin vm.stats.vm.v_swappgsout (I believe these results are COUNTER type values, like you get from netstat -inb. You could establish swap activity by plotting changes in this value.) Measure swap size: 0-13:38 [EMAIL PROTECTED] ~ swapinfo Device 1K-blocks UsedAvail Capacity /dev/ad0s1b 1040 104 0% 0-13:38 [EMAIL PROTECTED] ~ swapctl -l Device: 1024-blocks Used: /dev/ad0s1b 104 0 If you are trying to accomodate n+1 swap devices, try this: 0-13:44 [EMAIL PROTECTED] ~ swapctl -lsk Device: 1024-blocks Used: /dev/ad0s1b 104 0 Total: 104 0 Now, perhaps the next poor soul to Google this topic may get a slightly better answer. :) Thanks, -danny -- http://dannyman.toldme.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: cannot boot 5.3 after power failure - major bug?
stheg olloydson wrote: Thanks for the reply. I had tried that and kept getting the invalid format error. I am puzzled by the fact that I can get a directory list, but the boot loader thinks the format is wrong. Also it seems to be looking in /kernel and not /boot/kernel/. stheg, Is this a system that has been upgraded? My guess is that your boot loader was installed or configured for an earlier version of FreeBSD, where /kernel used to be the place to go ... and maybe you just don't reboot all the much, or something got knocked loose in the times before the power outage. At any rate ... check the handbook for how to replace your MBR (typically needed after installing Windows) which might do the trick. Otherwise, it is maybe missing some crucial hint from a file that got clobbered from the /boot or /kernel directories or something? I'd like to think that that will get fixed when you upgrade to 5.4. :) (If you really want to know the answer, find a good resource on FreeBSD bootstrap process.

Mike, Messy how? You keep an eye on gmirror list and it will tell you if one of the disks has died. If a disk dies, you swap in an RMA, and rebuild the mirror. If swap in the RMA involves downtime, then gmirror will see the new disk at boot and DTRT. Or have you seen too many horror stories on the mailing lists? Currently, I have a whole bunch of systems with one-off 3ware or Adaptec controllers, and I don't know how to monitor them reliably. I tried doing a 3ware a month or two back, and there was this crazy race between how old the binary versus the kernel module versus the firmware was and I just gave up. Grr! As RAID1 solutions go, gmirror take a lot of the headache out of administration.

Re: firefox share profile in freebsd and windows!
Ean Kingston wrote: At the worst, you could export your bookmarks from one and import them into the other. Then you would just have to go through the preferences and make sure the settings are the same otherwise. I have been using Amazon's a9.com which has a browser bar for Firefox that facilitates storing bookmarks on a9.com. This way, I can do bookmarks on my FreeBSD Firefox, and pull them up on my Windows Firefox, or any computer if I visit their site. There are probably other server side bookmarks services out there. The a9 makes it a little nicer with the toolbar thingus, plus it wraps around Google's search engine, Amazon's products search engine, and Amazon.com will give you a modest discount for helping test out their wonky new feature. (The bookmark management is a little weird, because it is implemented as a web interface.) As far as duplicating profiles, I'm with Ean in figuring that trying to get the profiles to work on two utterly different platforms sounds like more trouble than it would likely be worth. I know that in the old days the Netscape folks were keen on a project to store metadata in an LDAP server ... perhaps the Mozilla foundation has some similar fetish, but you would be better off asking the Mozilla folks, who are all about cross-platform magic. -danny ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
probe dmesg status of RAIDs -- twe and amr
Hello, I have a bunch of FreeBSD systems, many with hardware RAIDs. The problem is, I have no easy way of checking to see that they are okay. I tried once to get the 3ware binary to work with the 3ware kernel module to get to work with the 3ware firmware update that I had to ... ARGHH! It was awful. On the other hand, in /var/run/dmesg : twed0: TwinStor, Normal on twe0 twed0: 114472MB (234439600 sectors) twe0: command interrupt Or, on another system: amrd0: LSILogic MegaRAID logical drive on amr0 amrd0: 140012MB (286744576 sectors) RAID 5 (optimal) I know from experience that the Normal on the twed0 means nothing broken and I like to think the optimal on the amrd0 means RAID5 is doing fine. This is enough information for me . . . if a RAID is in a failure state, I can live with gracefully failing a server, if need be, and booting in to the BIOS to get the real information. The problem is, I only get these messages when I boot . . . and I don't boot very often, of course. I have tried poking around sysctl, atacontrol, camcontrol . . . all to see how I might probe out these messages on a regular basis, but I can not figure it out. Can someone give me a tip on how to pull up bits of dmesg output while the system is running? Or if someone has better advice on checking up on the status of various flavors of RAID . . .

FreeBSD HOWTO: Software Mirror System Disk
[ From http://dannyman.toldme.com/2005/01/24/freebsd-howto-gmirror-system/ ] A new feature of FreeBSD 5.3 is the ability to set up a software mirror of your system disk. This allows you to boot off either of a pair of hard disks, which will then function as a RAID1, which will ensure system uptime in the face of a single disk failure. As the documentation is a bit sketchy, heres a quick cheat sheet for setting this up with gmirror: (This crib sheet assumes you have a pair of identical IDE (in my case, SATA) drives identified as ad4 and ad6.) 1. Install FreeBSD on to ad4. 2. Reboot with the Install CD. 3. Enter Fixit mode, using Install CD disc2 as the live filesystem 4. # *chroot /dist* # *mount_devfs devfs /dev* # *gmirror label -v -b round-robin gm0 /dev/ad4* # *gmirror insert gm0 /dev/ad6* # *mount /dev/mirror/gm0s1a /mnt* # *echo geom_mirror_load=YES /mnt/boot/loader.conf* # *echo swapoff=YES /mnt/etc/rc.conf* 5. Edit /mnt/etc/fstab to convert ad4 - mirror/gm0 6. Reboot Thanks to the few dozen people who have come before me, and posted crucial hints to the mailing lists. Thanks also to Ralf S. Engelschall who has a far more verbose explanation of how to do this sort of thing with mis-matched disks. [See http://people.freebsd.org/~rse/mirror/ ] http://people.freebsd.org/%7Erse/mirror/ You should definately look over the gmirror man page, and review the output of *gmirror list gm0* when swapping out drives. You can disable automatic rebuild, etc. It is quite nice.
