FreeBSD, GPGPU and OpenCL/CUDA
Hello. The problem behind the subject is a little bit frustrating, so I do not know were to start. I use FreeBSD at my lab and private for scientific stuff. In most cases, FreeBSD performed sufficiently for tasks we/I had to do. But this picture has changed. Modelling atsrodynamical problems I need to order and setup new multicore computer boxes and the preferred OS in mind was still FreeBSD (even 9.0-CURRENT). We use a highly parallelized and CUDA supported modellig software solving symplectic integrational problems (moving stars and planets and even lost of particles in ring systems like saturn). Getting involved with CUDA, I was looking for solutions and tools for usage with FreeBSD (priority is: we need 64 Bit and due to several issues I had with the main infrastructure, like OpenLDAP, Linuxulator isn't a way to go). Since most of my colleagues overseas now use CUDA-supported GPGPU software with Linux, I was looking for some solutions using this software (written in C++ and Fortran 95) with FreeBSD. First, and this hasn't changed since the last 15 years, FreeBSD lack in support of professional Compiler vendors. Pprtland Group offers only Linux compilers, as far as I know Intel does not offer a native FreeBSD 64 Bit compiler. So we are stuck with gcc and gfortran, but this isn't an matter, if OpenCL/CUDA stuff could be used. But there is then the next problem. It seems that there is no real chance getting support for executing high performance code portions of our software in any way on a graphics card (gpu). Most FreeBSD driver doesn't support any 3D acceleration and as far as I know, the driver's support of 3D is essential for GPGPU usage. I looked for nVidia's native 64 Bit driver for FreeBSD, I found it, was happy having it, but then I realised that obviously CUDA isn't usable with this driver, since the CUDA SDK is not to be ported to FreeBSD and not even to 64 Bit FreeBSDs. Well, FreeBSD doesn't support 64 Bit Linuxulator as far as I know, so there is no chance getting software run in 64 bit environments using OpenCL/CUDA with nVidia GPUs, neither natively under FreeBSD nor with a 64Bit Linuxulator, is this right? I havn't looked deeper into AMDs offerings, but I guess since it's silent around OpenCL and AMD-based GPGPU, even with Linux there isn't much. I'm not very close to the GPGPU scene, we even start thinking about porting and developing some mathematical stuff into libraries and thought about OpenCL. Unluckily, in my team I'm the only one utilizing FreeBSD. Maybe someone out here has solved some problems and could email me. Even AMD seems to be a white spot in the subject of GPGPU and FreeBSD for me, maybe someone could shed some light on this.

Re : Re : Re : How to connect a jail to the web ?
I had a break with this yesterday. I've just tried your suggestions. It still doesn't work but the error message has changed. On the host when the jail is running : FreeBSD# jls JID IP Address Hostname Path 1 93.0.168.242MaPrison /usr/prison FreeBSD# ifconfig rl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:11:09:15:72:6a inet 192.168.1.38 netmask 0xff00 broadcast 192.168.1.255 inet 93.0.168.242 netmask 0x broadcast 93.0.168.242 media: Ethernet autoselect (100baseTX full-duplex) Where did you get that second IP address from? Did you just add it manually? Or is that the address that your gateway (DSL router, whatever) got assigned from your ISP? I added it manually in rc.conf (on the host) : jail_server_rootdir=/usr/prison jail_server_hostname=MaPrison jail_server_ip=93.0.168.242 I choosed it because that's my computer's public ip, at least according to this website : http://whatismyipaddress.com/ I assume that IP address is not really routed to your host, but that NAT (Network Address Translation) is used on your router. So you cannot use that address on the host. (If that's not true, please exlain the structure of your network in more detail.) My network is very simple. I've got a kind of modem provided by my phone company. It's called a neufbox and acts as a gateway. Its address is 192.168.1.1. This neufbox is connected to : - the phone network - a phone - the FreeBSD computer through an ethernet wire - two other computers via wifi When I browse address 192.168.1.1 with firefox, I can see a page telling this the neufbox, that internet and the phone are working, that the tv is not connected (that's true) and that it's public ip address is 93.0.168.242. It also gives its MAC address and various other infos. So, if my assumptions are true, you must use the address 192.168.1.38 for your jail. OK. In /etc/rc.conf, I changed this line (see above) : jail_server_ip=198.168.1.38 Make sure that DNS is working inside the jail ... It should be sufficient to copy /etc/resolv.conf from the host to /usr/prison/etc/resolv.conf /etc/resolv.conf only contains this single line : nameserver 192.168.1.1 I placed a copy of this file in the jail. After these changes and a complete reboot, I launched the jail and tried a portsnap fetch : FreeBSD# /etc/rc.d/jail onestart server Configuring jails:. Starting jails: MaPrison.

I tried this on the host : FreeBSD# ping www.freebsd.org ping: cannot resolve www.freebsd.org: Host name lookup failure In other words, it appeared that DNS was no longer working, even on the host. I rebooted again. This time, I didn't launch the jail. ping and Firefox worked perfectly well on the host as they had always did before. If it still doesn't work: Are you using any packet filter (ipfw, ipf, pf)? If so, please show the complete list of rules. No, I don't. You told me it was not necessary. Otherwise, it might help to run tcpdump(1) on the host, so you can see the actual packets that are transmitted and received.

CD burning woes, redux
Hi, My CD burning woes continue. I've replaced a power supply that was almost certainly marginal (kernel page fault failures during fsck on two drives at once, but not on one at a time) and put a brand new SATA DVD burner on the machine (LITE-ON iHAS124-04). uname -a reports FreeBSD silver.local 7.2-RELEASE FreeBSD 7.2-RELEASE #5: Thu May 20 09:45:44 EDT 2010 t...@silver.local:/usr/obj/usr/src/sys/SMP-GONDOLIN i386 Power supply is a new 400W Rosewill; MB is by Asus, processor is a Core 2 Quad running at (I think) 2.25 GHz. (It's under 2.3.) I added an MSI GeForce video card (X doesn't want to run on the mobo video). There are two SATA disks, both 7200 RPM and neither in service for very long. (I only buy 5-year-warranty drives.) They are in a carrier with a fan and are cool to the touch. The processor cores run between 49 and 57 C; the NB chip has a big copper heat sink with an 8 CFM fan; HS is warm at the bottom and cool at the top. This worked a few weeks ago, when I burned about forty of these Archival Gold disks. cdrecord -v reports that they have the same chemistry and write strategy as the TDK cheapies. I've tried with both atapi/cdburn and atapicam/cdrecord. I've tried with both TDK CDs and the expensive archival-grade discs I'm trying to burn. The operation pauses for a very long time, the activity LED on the drive flashes, and I get console messages thus: Aug 14 07:03:50 silver kernel: acd0: TIMEOUT - WRITE_BIG retrying (1 retry left) Aug 14 07:03:50 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:03:51 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:03:51 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:04:31 silver kernel: acd0: WARNING - unknown CMD (0x4a) taskqueue timeout - completing request directly Aug 14 07:04:31 silver kernel: acd0: WARNING - unknown CMD (0x4a) freeing taskqueue zombie request Aug 14 07:04:51 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:04:51 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:08:13 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:08:52 silver kernel: acd0: TIMEOUT - WRITE_BIG retrying (1 retry left) Aug 14 07:08:52 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:08:53 silver kernel: acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly Aug 14 07:08:53 silver kernel: acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request Aug 14 07:09:33 silver kernel: acd0: WARNING - unknown CMD (0x4a) taskqueue timeout - completing request directly Aug 14 07:09:33 silver kernel: acd0: WARNING - unknown CMD (0x4a) freeing taskqueue zombie request Lather, rinse, repeat. Sometimes it makes it to the end of the disk, more often with the cheap disks that with the $2.00-to-burn-a-coaster archival disks. I get about the same messages whether using atapi or atapicam. I have had the whole machine lock up twice. Once it was apparently a disk system lockup; I could get prompts but nothing would run. It freed up, apparently after something was run, the other time it stopped responding to the console keyboard in any way and nothing moved on the display. The drive seems to only want to write at speed 48. Using cdrecord speed=0 (use slowest available) is runs at the same 48 that it runs at with no speed= . I will be grateful for any suggestions.

ZFS not usable on FreeBSD-8.1
I run FreeBSD-8.1/amd64. I have used ZFS for four years on (Open)Solaris, so I have some experience with it. It always served me very very well. However, I cannot get it to work on my SATA2 drives. At first I thought they'de suffer from something from there OpenSolaris ZFS mirroring. So, I wiped out the drives completely by writing zero's to them. Then I created a ZFS zpool on one drive, destroyed it and created a mirrored zpool on my 2 Tb drives. It seemed OK; files could be written and removed to/from it. A new zfs filesystem worked OK too. *HOWEVER*, the moment I *do* something to the zpool like zpool scrub pool I get a vdev failure (type=vdev.bad_label) and the pool is ruined. It can't be destroyed or exported anymore. It's just a waste. I tested this behaviour on 10 different drives. Four of them brandnew. It happened everytime again. It is not the drives! Booting into OpenSolaris b134 I am perfectly able to create workable ZFS mirrors out of the drives. I can also scrub them ;-) ;-) or whatever io related thing I want to do. This leads me to the conclusion that something is definitely wrong with ZFS in FreeBSD-8.1/amd64. For the moment I created some gmirrors on a couple of drives, but man, how I'd liked to have zpools. They work zo much sweater/easier. Am I alone in these matters? Are there any known issues regarding ZFS.

My consideration is, then, give the server 2 minutes on battery. If full power has not been returned, shut down the server but leave the modem (w/ wireless) and switch running with power for up to 6 hours. A bit of advice: If this is an unattended system, give some thought to how you will boot the server back up if the outage is longer than two minutes but shorter than six hours. Most UPS installations have *some* kind of race condition issue if power comes back after the servers have begun a shutdown, but in your case it's an unusually long window. Meaning that my 2-minute window is unusually long? If the UPS can support the system for 12 minutes, I say give it 20% of the life of the support because our power outages here are usually spikes that kill my current web server (but amazingly *not* my file server). In fact, one of those power fluxes occurred last night. I love storms for the light shows, but hate them for the toll they take on my servers. Indeed. Ryan, I'm coming in late but I've read the whole thread, after many people have added useful insights. However I must question your initial power estimate for this server; in your first post you said (cutting a bit): I am looking at a 1400VA / 980W UPS to run a single server with a usually not on monitor, a DSL modem and a simple switch. The server should generate about 330W in power consumption, the monitor another 50-100, the modem about 10 and the switch about another 10 watts. So: UPS: 1400VA Server: 400W (liberal estimate) Modem: 10W Switch: 10W Monitor: 75W Total: 495W First, forget the monitor. You said it's usually off anyway, as you'd expect on a server. Plug it into the mains directly as needed, not on the UPS. Or at least use DPMS to suspend it after a minute or so idle. Secondly, get a power meter and actually measure your server running. Unless it's a real monster, it will likely draw less than 200W in normal use, possibly much less if using powerd to moderate CPU speed by load. So I suspect you may get something like 5 times the full-load rated time out of your 1400VA UPS, maybe 20-25 minutes or so. 5 minutes should be a comfortable runtime, to shut it down with 70-80% capacity remaining. Thirdly, I'll second using another UPS (eg 300VA units are cheap) for powering other than your server. That way you can use features of your software (eg NUT) to properly signal the UPS to shutdown (irrevocably) just after your server shuts down, to get proper resumption when power returns. Should you get multiple successive on-battery then on-mains events, good UPSs will delay restarting until there's enough capacity to run another cycle, which time may be tunable for your requirements. Additionally I spent $34 on a video card today that reduces my power consumption by 150Watts, resulting in a $13 per month savings in my powerbill - in MN we have a fixed-rate utility fee structure per season (winter power costs less than summer, I believe, for whatever reason) and a $10 mail-in rebate on the card means I will be turning a net profit in 2 months! -- Ryan Sorry, I don't get why you'd run a video card using in excess of 150W on any server? Or is that for your hot gaming box? :) cheers, Ian ___ 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

When somebody complains that they receive spam via your relay they must the very least forward one of the offending mails to you so you can study the header. If they deleted the message simply instruct that the next spam mail is forwarded to you. In the header you can check the Received headers to see if it actually passed through your server first check ip hostname, then see if the message id appears in your logs.

Later , they started to send me suggestions about how to remove proxy server acquired in my computer which is sending bulk spam messages . All of their text suggestions were complete executable codes . All of the messages were using faked names of my ISP officials . They tried very hard to infect my computer . At the end I have send a complaint message to my ISP authorities . After that , even I have received many such messages . In those days they are not sending such messages , or they are prevented by my ISP systems , I do not know . Based on such an experience , please be careful about such claims , and do not try to decompose their message attachments because their names of message attachments are also not related to content they contain . Use programs to dissect such messages without making any harm to your systems , for example convert their extensions to .txt and try to read them by a text editor . If they are really texts , they should be readable . Even , content of some messages were completely executable binary . I think some criminals started to perform such a ploy to infect computers by persuading users to try to clean their computers by applying their advices based on generated fear on attacked persons .

Re: ZFS not usable on FreeBSD-8.1
Dick Hoogendijk writes: I run FreeBSD-8.1/amd64. I have used ZFS for four years on (Open)Solaris, so I have some experience with it. It always served me very very well. However, I cannot get it to work on my SATA2 drives. At first I thought they'de suffer from something from there OpenSolaris ZFS mirroring. So, I wiped out the drives completely by writing zero's to them. Then I created a ZFS zpool on one drive, destroyed it and created a mirrored zpool on my 2 Tb drives. It seemed OK; files could be written and removed to/from it. A new zfs filesystem worked OK too. *HOWEVER*, the moment I *do* something to the zpool like zpool scrub pool I get a vdev failure (type=vdev.bad_label) and the pool is ruined. It can't be destroyed or exported anymore. It's just a waste. I tested this behaviour on 10 different drives. Four of them brandnew. It happened everytime again. It is not the drives! Booting into OpenSolaris b134 I am perfectly able to create workable ZFS mirrors out of the drives. I can also scrub them ;-) ;-) or whatever io related thing I want to do. This leads me to the conclusion that something is definitely wrong with ZFS in FreeBSD-8.1/amd64. For the moment I created some gmirrors on a couple of drives, but man, how I'd liked to have zpools. They work zo much sweater/easier. Am I alone in these matters? Are there any known issues regarding ZFS. I know there are some in FreeBSD-9 (at least I saw some reports on vdev.bad_label messages) on nabble.com You haven't provided enough information for me to make a concrete suggestion, but this kind of thing often seems to boil down to something getting confused over slices and partitions when they both have the same extent (start-end) on disk. This used to bite me in the gmirror world until I learned to make the partition one block smaller than the slice it lived in. Are you using explicit device names to add the disks to your pool? If so you'll gain robustness by using labels, either glabels as described here: http://submesa.com/data/bsd/zfs or if you're in the gpt world then gpt labels as described in the gpart commands illustrated here: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror g. ___ 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

You can try it yourself, with telnet and proper smtp commands. For example, telnet from outside of your organization to your mail server and issue: ehlo mydomain.com mail from: foo...@example.com rcpt to: foo...@example.org data test mail . You actually have to get error message about relay denied for you. If you don't - you're in trouble. If you do recieve such message - you relay is closed and probably you have spam worms who send emails from legit user, or something like that. The basic test, but hardly sufficient to determine if all the known ways of fooling an smtp server are accounted for. Recall from the OP's description: saying relaying was denied in 17 separate tests. The above also can be an issue if you do the test from an IP address that the SMTP server has been configured to treat as trusted. --Jon Radel j...@radel.com

cg0: bad magic number
My 1Tb sata2 drives work very well with FreeBSD. They can be sliced, partitioned and newfs can be run. However, no matter what I try (sysinstall, gpart) when I slice my 500Gb drive and create a partition in it (1 block smaller than the slice) I can not newfs the /dev/ad8s1a It always end up with a *cg0: bad magic number* Googling I find a lot of references, but none give me the answer to my problem. All 500Gb drives can be formatted under Windows, linux (Ubuntu), Partion Magic, Solaris without errors. Alas, non of these systems supports formatting in UFS2. I need FreeBSD to do that but this fails... I'm getting quite depressed about this. Espescially because I cannot find the answer to this issue and I hate that!

Re: UPS question
Just going to reply to this one bit for now: The computer used to be a gaming computer, converted this past fall into a file server when I lacked time to play any games in a year. Additionally I spent $34 on a video card today that reduces my power consumption by 150Watts, resulting in a $13 per month savings in my powerbill - in MN we have a fixed-rate utility fee structure per season (winter power costs less than summer, I believe, for whatever reason) and a $10 mail-in rebate on the card means I will be turning a net profit in 2 months! -- Ryan Sorry, I don't get why you'd run a video card using in excess of 150W on any server?

Re: Open Mail Relay
Is Abuse.net's test adequate to rule out an open mail relay problem? It's pretty thorough, and most MTAs have default configurations that don't permit relay, so it's much less of a problem than it was when I wrote the tester many years ago. I don't try to check for weak SMTP AUTH passwords, a hole that some spamware exploits, so if you do AUTH, it's conceivable that could be it. In your case, though, I would wait for the complainer to forward you a message or two with headers so you can figure out where is spam is coming from.
