I have installed free bsd 7 on on Intel Xeon Machine with 1 Gb ram. But i cant use the mailing facility .. i can send mail by typing [mail username] then follows the subject and message then EOF. but i when i check mail of that particular user it shows No mail for that user ??

How to eject an USB disk on FreeBSD
Hello, Is there a command in FreeBSD that ejects a USB disk like in Windows? I mount the USB disk with automount daemone (amd). I have a script that access this disk and force an umount at the end of the script. But anyone accessing the disk will have amd re'mount the disk and at the time I unplu the disk, problem may occur because the disk is still mounted and in use. I would like to have a command that makes the disk/USB port physically inaccessible, so at the end of the script a user cannot access the disk again. Like in Windows after stopping a USB mass storage device, one has to unplg and replug the disk if he wants to access it again.

I think they probably did, NTFS took a lot from UNIX filesystems, and at the time it was released they said that NTFS didn't need any defragmentation at all. No, if you check a NTFS disk after some work, it's heavily fragmented. As you fill it and work with it, it becomes more and more fragmented. I suspect that it's mostly a matter of attitude. Windows users have an irrational obsessive-compulsive attitude to fragmentation, so they end-up with good reliable defragmenters, and so less reason not to use them. We don't really care, so we end-up with no, or poor, defragmenters, which reinforces our don't care attitude. The best way to defragment a NTFS drive is make a backup to other device, format the original and recover the backup. It take less time and device don't suffer. I do it monthly with the data disks and performance grows espectacularly (near x4 on sustained file read). --- Este documento muestra mis ideas. Son originales mias.

Wireless and Broadcast packets problem
Hi Guys I am having a problem with my wireless network. The Issue is that clients connected to the wireless LAN cannot _see_ other clients. My understanding of 802.11 was that clients could talk to other clients, except all traffic would go via the access point and that the AP would forward on the packets. This also ensures that encryption works as expected as well as other RF issues. One thing that I can see is going wrong is that clients on the Wireless Lan sending Broadcast packets, but they are not being forwarded by the AP to anyone else... Wireless clients also cannot ping each other (mainly because their ARP requests are not being answered) Below is a simplified system diagram. AdriansPC AlbertAP \|/ - 192.168.123/24 | ||--LAN--bge0-||---| ral0 (192.168.124/24) ||||--tun0---PPPoE(bge0) WindowsFreeBSD Sneaky\|/ -| ||---| 192.168.124.2 (Static IP address) || ral0 FreeBSD Laptop\|/ -| ||---| 192.168.124.150 (DHCP) || Windows When running TCPDump on AlbertAP I can see plenty of wireless traffic going around the place. Wireless Clients are able to connect and have their session is encrypted with WPA. This all seems to work, wireless clients are able to browse the net. (Those that can get an IP address anyway, which happens to be the windows machines) *Problem* I have run tcpdump on both AlbertAP and Sneaky and seem some interesting omissions. When I ping Sneaky from Laptop I see on Albert the ARP request come out from Laptop asking for Sneaky's MAC address. AlbertAP tcpdump -i ral0 10:27:51.979664 arp who-has 192.168.124.2 tell 192.168.124.150 10:27:51.979684 arp who-has 192.168.124.2 tell 192.168.124.150 But on Sneaky I cannot see these packets comming in... All I get is random EAP traffic Sneaky tcpdump -i ral0 10:30:32.987961 EAP code=2 id=3 length=123 10:30:32.988383 EAP code=1 id=3 length=95 10:30:32.990557 EAP code=2 id=3 length=135 10:30:32.991548 EAP code=1 id=3 length=95 However if a Wired client like AdriansPC tries to ping Laptop then things work. Albert knows the MAC address of the Wireless client to send the ping packet to and so just sends it off. *Problem* The other thing I see alot of is netbios broadcast traffic coming from the Laptop on the wireless. Albert can see all this traffic coming in, but none of it gets forwarded to Sneaky, (nothing about netbios from a tcpdump on sneaky). The same can be said for a particular client doing DHCP/BOOTP. On AlbertAP, I see the request come in and see the response go out (the response goes to 255.255.255.255) but I do not see this on sneaky (I should right, its a broadcast address). Oh and I don't think this client is actually getting a response as I can't do much with it(ie ping). (Its a wireless print server) Interestingly enough DHCP does seem to work to Laptop. I believe that this is because windows is doing DHCP, where as my print server is doing BOOTP. *It does work* Just so you believe me that normal traffic does get around, here is a ping from sneaky to albert. Sneaky tcpdump -i ral0 10:36:11.243678 arp who-has 192.168.124.1 tell 192.168.124.2 10:36:11.244634 arp reply 192.168.124.1 is-at 00:1a:ee:00:d5:c0 (oui Unknown) 10:36:11.244693 IP 192.168.124.2 192.168.124.1: ICMP echo request, id 18949, seq 0, length 64 10:36:11.251920 IP 192.168.124.1 192.168.124.2: ICMP echo reply, id 18949, seq 0, length 64 AlbertAP tcpdump -i ral0 10:36:11.241001 arp who-has 192.168.124.1 tell 192.168.124.2 10:36:11.241017 arp who-has 192.168.124.1 tell 192.168.124.2 10:36:11.241042 arp reply 192.168.124.1 is-at 00:1a:ee:00:d5:c0 (oui Unknown) 10:36:11.248582 IP 192.168.124.2 192.168.124.1: ICMP echo request, id 18949, seq 0, length 64 10:36:11.248600 IP 192.168.124.1 192.168.124.2: ICMP echo reply, id 18949, seq 0, length 64 *Discussion Point* I find it interesting that sneaky asks for 192.168.124.1's MAC address with an ARP request, but albert got two of them... *System Details* Things are basically setup as detailed in the Handbook, with the wireless LAN on a different Subnet to the wired one. I have also had a go at bridging the two interfaces but ran into trouble so didn't spend long there. I expect I would have the same issues.

We don't really care, so we end-up with no, or poor, defragmenters, which reinforces our don't care attitude. Companies like Executive software make money off Diskkeeper by running tests that demonstrate that defragging is wortwhile. I've seen all sorts of benchmarks, and I've seen the ones where they demonstrate that NTFS really does have a fragmentation problem, unlike MS early claims. If UFS or ext2 had fragmentation problems, some company would have jumped on it by now and be marketing a disk defragmenter for Linux/etc. Also, accessing a FS by block device and relocating file data isn't a terribly difficult thing to do, so I have a hard time believing that nobody's tried it ... my guess is that they've simply found that it wasn't worth doing. FAT had a fragmentation problem because it wasn't really designed, it was just thrown together. MS was lucky it didn't have bigger problems. I think NTFS has a fragmentation problem because it wasn't a priority. MS was focused on building a filesytem that could store the outrageous ACLs they wanted, and that was non-trival (look at how long it took the BSDs to have native file-level ACLs).

Re: defrag
Maybe it is because FAT filesystem wasn't well designed from the beginning and defrag was a workaround to solve performances problems. as everything else microsoft did it wasn't designed but stoled, possibly slightly changed. FAT is similar (mostly the same) as CP/M filesystem. CP/M was single-user and was used on floppies up to 360kB AFAIK, small enough to be able to keep most metadata in memory, even for small hard disks FAT was stupid. The only innovation of Micro$oft was subdirs ;) FAT does NOTHING to prevent fragmentation, simply gets the first block availble when needed. NTFS is a theft of OS/2 HPFS. they didn't even bothered to use other partition ID :), but they managed to f..k^H^H^H^Hextend it's functionality, so it's actually even slower than FAT, and too - does nothing to prevent fragmentation. This is normal, as Microsoft make a problems to be able to fix it (creating 3 times more others) in new releases, so idiots continue to buy new versions of windoze and new hardware, just to do as simple task as writing a few-paged document or view a webpage ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: defrag
No, if you check a NTFS disk after some work, it's heavily fragmented. As you fill it and work with it, it becomes more and more fragmented. it's just like FAT, because nothing is done to prevent fragmentation. if NTFS needs to allocate block, it simply get first free. consider writing to 3 files, one block at a time to each. you will get block arranged like this (where 1 is file 1's data,2 is data from file 2 and 3 from file 3): 123123123123123123123123213213 with newer systems with lots of memory windoze POSSIBLY delays allocation, so it may somehow prevent allocation if these files are written within short period. but there is no real thing, as simple and efficient as in BSD UFS. The best way to defragment a NTFS drive is make a backup to other device, format the original and recover the backup. It take less time and device don't suffer. I do it monthly with the data disks and performance grows espectacularly (near x4 on sustained file read). did they finally managed to be able to backup everything just by copying files like in unix? is there any way to restore it without doing windoze installation on blank drive? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: defrag
MS was focused on building a filesytem that could store the outrageous ACLs they wanted, and that was non-trival so - as usually - they quickly implemented OS/2 filesystem (at best, assuming no stolen code), and added their bloat then. performance is never a priority in Microsoft. exactly opposite is true. High quality of windows will kill Microsoft, few would buy new versions then. (look at how long it took the BSDs to have native file-level ACLs). because in unix they are not actually needed. usersgroups system is just perfect. i don't know anyone here that actually use ACL under unix because he/she needs it.

gjournal fsck
Hi all. I'm having some problems with several servers I've built recently (7.0-RELEASE) that are using gjournal. I had two reboot a few days ago (un-related to FreeBSD problems I think)...but when they came back up, the file systems wouldn't mount since they were not clean. Now, I understand that UFS knows nothing about the fact that it's journaled, and the journaling knows nothing about UFS...but it's my understanding that by using gjournal, you should really never need to fsck a file system. However, the only way to get them to mount is by doing the fsck. Is there something else I should be doing instead of fsck? And since I know it will probably come up, I built the file systems using the instructions and notes at http://www.freebsd.org/cgi/man.cgi?query=gjournalapropos=0sektion=0manpath=FreeBSD+7.0-RELEASEformat=html.

Problem in FreeBSD 7.x, in Xorg switching consoles.
When I switch from my Xorg running KDE, for some reason it pushes a string as keypresses to the KDE. I do not know if it's on return, or on exit. Here is my setup! On tty3 is my Xorg KDE desktop. On tty8 is a getty login. I use alt+ctrl+f8 to enter the login screen on tty8. I then switch back by using alt+ctrl+f3, and enter the KDE desktop. But then for some reason something crazy happens. If i was using the konqueror web browser, the address would get replaced and it would go to a bogus website. So I decided to put up a blank text pad in kedit to see what happens. What I get is a url string is pushed to the pad. I believe this happens when coming back to the Desktop KDE. In Love in Jesus Christ, Or Lord and Savior.

This support is native to 8-CURRENT, I think most of it is backported to 7.1. 2. Is there any way to force UP operation apart form recompiling kernel without SMP option? mostly - if you have a SMP kernel it will always use SMP locking and scheduling algorithms, which are in 6.x somewhat slower than the UP variants. You can force the kernel to use only one CPU with machdep.hlt_cpus sysctl: sysctl -d machdep.hlt_cpus machdep.hlt_cpus: Bitmap of CPUs to halt. 101 (binary) will halt CPUs 0 and 2. (note that you have to give a decimal number to the sysctl) 3. Can someone shed some light on the logic of how schedulers (4.4.BSD/ULE) dispatch processes among CPUs? 4.4BSD has a single queue of running threads from which the threads are dispatched to CPUs when needed, in a way that's similar in effect to round-robin. ULE has separate per-CPU queues and is aware of CPU topologies so it knows that dispatching threads to cores on the same physical CPU is better than picking a distant CPU. (this is all about ULE in 7-STABLE and 8-CURRENT. ULE in 6.x is broken). This is why 4.4BSD scales less well than ULE (but on the other hand 4.4BSD has had many decades of hand optimizations and there are even now reports that it behaves better in some edge circumstances). signature.asc Description: OpenPGP digital signature

Re: defrag
On 8/27/08, prad [EMAIL PROTECTED] wrote: something that has puzzled me for years (but i've never got around to asking) is how does *nix get away without regular defrag as with windoze. Essentially, the UFS file system (and its close relatives) is intentionally fragmented in a controlled way as the files are written, so that the effect of the fragmentation is limited. Files are written at sort-of-random locations all over the disk, rather than starting at one end and working toward the other, and there is a limit to how much sequential disk space a single file can occupy (a large file essentially gets broken up and stored as if it were a collection of smaller files). The result is that as long as there is a reasonable amount of empty disk space available, it will be possible to find space to store a new file efficiently. This is why the filesystem wants to have at least 8% empty space. If you have less than 8% empty space left on the filesystem, it switches from the speed optimizing mode that I just described to a mode that tries to pack things into the remaining space as efficiently as possible, at the cost of speed. FreeBSD also by default reserves some disk space for administrative use that is not available to normal users. One result of this scheme (and other issues) is that access time for large files suffers a bit (but not as much as it would if they were heavily fragmented). If you are setting up a volume mainly for storing large files, you can adjust some of the parameters (e.g. using tunefs(8)) so the filesystem will handle large files more efficiently, at the expense of wasting space on small files. fsck is equivalent to scandisk, right? Pretty much. It looks for errors and tries to fix them. It does not attempt to defragment the disk. Unless the disk is almost full, defragmenting probably wouldn't improve things enough to matter. so when you delete files and start getting 'holes', how does *nix deal with it? The process of scattering files all over the disk intentionally leaves holes all over the disk (that's what I mean by controlled fragmentation). When you add and delete files, those holes get bigger and smaller, and merge or split apart, but until the disk gets very full, there should always be holes big enough to efficiently store new files. The difference between this and what happens in a FAT filesystem is that the process is designed so that there is a statistically high likelihood that the holes produced will be large enough to be used efficiently. -- In friendship, prad I hope that helps. And as usual, if I got any of that wrong, someone please correct me. If I answer this question often enough, I will eventually get it right, then perhaps we can make it a FAQ ;-) - Bob ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

32-bit fbsd binaries on amd64 (we can already run 32bit linux/fc4 stuff, so this should work, right?)
I've been reading the wine64 wiki. I've also seen some of myself other's questions in this general direction (not wine specifically, but anything 64 vs 32) go by. Near as I can tell, the big hangup is having 32-bit libs (i.e for X) hanging around on your system. Now, I'm sure, as usual, I'm being naive, but: 1) We can run 32-bit linux on amd64, so do we have 32-bit freebsd libs already? 2) If we don't have the 32-bit libs, is it possible to steal them directly from the corresponding i386 freebsd (as long as we haven't rebuilt our kernel too many times), or should we in all cases be building them (is there a wiki? I'm sure setting the CFLAGS for 32-bit (saw that somewhere) and buildworld is not the right way, unless we manually copy things). 3) Once we have all the libs set up, how does one spoof a port (i.e. linux/fc4-base or, in my case, wine) into building 64-bit? I guess fc4 is easy because it's pretty much a binary download, right, which is not going to be the case for wine, unless maybe we use the pkg.tgz (if we can do that, how would one force a 32-bit pkg to install on amd64?) It sure seems like there's a path to this coming soon. It's not just a matter of wine, I'd like eventually to run matlab64 (which is, of course, in the opposite direction), and I note people working on linuxulator64... In the meantime, I'm going to attempt to get wine going in my fc4 emu, but since I'm a FBSD snob, I consider that a very ugly hack...having to run my FPGA compilers and Matlab in fc4 is insulting enough ;) I was so bloody impressed by the performance difference between wine kqemu on fedora, however, that I am compelled to try (darn CAD vendors).

Any help would be greatly appreciated! Thanks! --Brian You may wish to have a look at this article: http://www.freebsd.org/doc/en_US.ISO8859-1/articles/gjournal-desktop In particular, you should make sure you use tunefs to enable Journaling and disable soft update on the journaled filesystems, i.e.: tunefs -J enable -n disable /dev/ad0s1f.journal Mount them using the async option: /dev/ad0s1f.journal /usrufs rw,async2 2 Note that the pass # still indicates the filesystem should be checked. While I was writing the article, I was trying several scenarios were I had the pass # set to 0, thinking that a gjournaled filesystem would not need fsck at all. I would then press the reset button. In most cases, the system would refuse to mount them. However with the pass # set, the fsck would finish almost immediately, since the actual consistency check takes place when the gjournal module is loaded (you will get a journal consistent after a bad reboot) and before fstab is even parsed. All fsck does in this case is simply confirm to the system it is a clean volume. In short, leaving the pass # to something that would cause an fsck is the safe way to go. The fsck will be almost instant anyway. Not exactly. Gjournal handles all inconsistencies, except one - orphaned files. An orphaned file is a file that some open, deleted, but haven't closed. If you have panic or power failure at this point, there will be unreferenced file. When fsck detects that it operates on gjournaled file system, it will do a very fast lookup of such orphaned files. It is optimized so that total number of such files is kept in superblock - if this counter is 0, we're done. If it is not zero, then fsck scans only cylinder groups headers, there is another counter in each header says how many orphaned files is in this CG. If CG's counter is 0, the whole CG can be skipped. Once we found X dirty CGs (X is stored in superblock) we can also stop earlier. All in all, there are very few such files (if any), so fsck is way, way faster with gjournal (eg. ~1 minute instead of ~8 hours on huge file system). -- Pawel Jakub Dawidek http://www.wheel.pl [EMAIL PROTECTED] http://www.FreeBSD.org FreeBSD committer Am I Evil?

Re: Proxying broadcasts? SOLVED
Hey,
The simple answer is no: if you want subnet-local broadcast traffic to
be received, then your DB servers and your clients need to be on the
same subnet. Routers are designed and required to not propagate
broadcast traffic, although you could switch to doing bridging rather
than routing. Or, you could set up Sybase's SQL.INI to list all of the
databases you care about, if I recall correctly...
Actually, a little perl script (running daemonized on the firewall) for
each of the USERS networks solved my problem. It is somewhat ugly, but it
works.

Network Card issues logging and aMule
Hi everyone I am currently using Marvell Yukon's 88E8053 Network card and after a few searches on google, i noticed that this card has a few issues. Fortunately, I could use the network card without the need to do any manual labor. However, I noticed that the network card crashes after perhaps 72 hours of moderate to intense workload. This has happened during the middle of scp, aMule downloading and many other different types of application so I don't think that this is related to any programs in general. I would like to know how I could log the activities of my network card or at least be able to find out how I could diagnose this problem. What are the steps that I should do? Second, my aMule crashes unexpectedly after a couple of days. This causes me to lose all my connections and queues so I am wondering whether there is a method to diagnose this since the log file generated by amule under ~/.aMule (logfile and logfile.bak) normally doesn't tell you much about it.

Re: defrag
Essentially, the UFS file system (and its close relatives) is intentionally fragmented in a controlled way as the files are written, exactly that was invented over 20 years ago and still it works perfect. at sort-of-random locations all over the disk, rather than starting at it's definitely NOT sort of random. it divides disk onto cylinder groups. it puts new files to the same cylinder group as other files in the same directory, BUT when files grow large (like over 1MB) it FORCES the fragmentation by switching to other cylinder group. the reason is simple - having file fragmented every few megs doesn't make a speed difference, while it keeps every cylinder group from filling out. for small files there will be almost always space available in the same cyl group. seek time within cylinder group is in order of 2-3ms at most. UFS from the beginning optimized for rotational delay too, by dividing tracks into multiple angle zones, so if it has to fragment within cylinder group, it choose the space in the zone that after head movement it will be shortest rotational delay possible. same for seeking between inode and file data. unfortunately - modern drives hide real geometry, so such optimization doesn't work any more. this is quite a large loss, for 7200rpm drive one rotation is 9 ms, average rotational delay 4.5ms, could be half that or less with such optimization possible. UFS does not just prevent fragmentation, it tries to manage it (as unavoidable thing) to make it's effect as little as possible. all of this worked fine and efficient on about 1 MIPS computer like VAX, after that UFS was changed a lot, but this basic mechanism is still the same. except extreme cases there is never need for defragmenting UFS filesystem!!! the remaining space as efficiently as possible, at the cost of speed. while it still can keep fragmentation quite low with much less space available (unless it's really close to 0%), this low speed means mostly higher CPU load when selecting blocks to allocate. on modern machines like 1Ghz or more it's difficult to see any difference. large files, you can adjust some of the parameters (e.g. using tunefs(8)) so the filesystem will handle large files more efficiently, at the expense of wasting space on small files. rather by newfs, by making huge blocks like -b 65536 -f 8192, and make MUCH less inodes (like -i 1048576) still - it will lose about as much space then as FAT32 with 8kB clusters, which is AFAIK default for FAT32 on large drives. with huge files, such settings may not only speed things a bit, but actually save space by not reserving that much for inodes and bitmaps. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have tried tuning for large files UFS offers near-raw performance. it can't be much better. it can be less efficient on concurrent operations because MAXBSIZE is 128KB on FreeBSD. i don't know why it's still that small! i changed #define MAXPHYS (128 * 1024) /* max raw I/O transfer size */ to #define MAXPHYS (1024 * 1024) /* max raw I/O transfer size */ on EVERY machine i own (except those having 128MB RAM) and it works fine, while there are huge difference. you WILL saturade gigabit ethernet port with just 2 gstriped drives and many concurrent users fetching files. make sure gstripe use huge stripes not small (like 256MB), to speed up multiple concurrent access instead of single linear read speed. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Network Card issues logging and aMule
Hi everyone I am currently using Marvell Yukon's 88E8053 Network card and after a few searches on google, i noticed that this card has a few issues. Fortunately, I could use the network card without the need to do any manual labor. However, I noticed that the network card crashes after perhaps 72 hours of moderate to intense workload. well i was unfortunate enough to use it once in new server (it was integrated on motherboard). with server like load it never worked more than a few hours. the simplest solution is to buy some network card and plug it to your computer ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: How to eject an USB disk on FreeBSD
Is there a command in FreeBSD that ejects a USB disk like in Windows? I mount the USB disk with automount daemone (amd). You have to umnount it using the umount command usually umount /mountpount does the tick The disk is mounted by automout daemon (amd), so any access to the disk will remount it, even if it has been umount'ed.

It wasn't (straight-up) theft; MS cut a deal with IBM to use HPFS and OS/2, more or less in exchange for letting IBM licence Windows 3.1 as WINOS/2 When things went sour - google provides days of happy reading if you're interested - MS morphed it into NTFS for NT, cruelled the deal with IBM so OS/2 couldn't run NT/Win95 apps (signing OS/2's death warrant, though it took a long time to die) and stopped distributing OS/2 themselves.

HPFS was a very resiliant and reliable filesystem. If you compare: % find /usr/src -name *hpfs* with % find /usr/src -name *ntfs* you'll go 'hmmm ..' and if you look through the sources you'll see whole large slabs of code that are shared between those two implementations, by the same author. I've never tried writing to HPFS volumes, but I did recover many years of work and play from a number of HPFS disks and still hope to do some more someday, so I was glad to see the code is still there in 7.0 .. cheers, Ian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Make World Inside Jail
I currently use a separate machine to make world and to make and archive ports and packages. I would like to retire that machine and move that functionality into a jail. I am due to switch to 7.1 from 6.3 soon. I understand that I cannot run divergent kernels in the jails. I could still make a 7.1-RELEASE world on a 6.3-RELEASE jail and installworld into the jail. That would leave me with a very strange jail system with a new generation system (binaries / libs / includes / utils / ports) with an old generation kernel. The only purpose of the jails is compiling world and installing ports. The parent system on which the jails reside cannot be made unreliable due to running the mishmash old/new jails. I'll need to run NFS servers and telnet servers inside the jails. Systems on my network would mount the jail's /usr/obj, /usr/src and /usr/ports via NFS to facilitate installworld and port upgrades. Can I make this work? Am I asking for trouble?
