devfs and hot unplugging
I was transferring a bunch of data files from compute nodes to a server using dump-restore. I put the disks with the data files into an external firewire device, plugged it in, and did the transfers. This is on 6.1-RELEASE-p6. When I finished the transfers, I just pulled the cable (the firewire disk partitions were not mounted). When I plugged in the next drive, devfs created devices with names like /dev/da0s1aa, /dev/da0s1ab, /dev/da0s1ac, etc., in addition to the regular /dev/da0s1a, etc (which were left over from the first disk, they were not destroyed when I pulled the cable). When I tried to fsck the firewire disk partitions, /dev/da0s1a and /dev/da0s1g worked fine (as did the dump/restore from /dev/da0s1g). The other partitions, /dev/da0s1d, e, and f, failed, saying the superblock could not be found. All the data disks were of the same kind and had identical partitioning schemes. My question: Should I be doing something to signal devfs I'm going to unplug a device so it won't get confused when I plug in another similar, but not the same, device? What's going on here?

Apache & PV entries
Hello list, I am configuring a very heavily used apache webserver, that required some special needs. This particular configuration needs to have at least 1024 httpds always running. Reaching this number is not a problem, but whenever I stop apache via apachectl stop, I notice all the httpds take a long time (1 min) to vanish - and meanwhile, top shows most of them locked. The states I see in top are: *vm ob RUN while the header shows: 1038 processes:332 running, 12 sleeping, 694 lock The numbers vary a lot. Eventually, they get killed, but it takes too much time. After some searching, I found out the cause for this was running out of PVs. I've added the following relevant options to the kernel: options KVA_PAGES=768 options PMAP_SHPGPERPROC=5120 sysctl vm.zone | grep PV shows: (note: httpd stopped here) (limit) (used) (free) (requests) PV ENTRY: 24, 84410445, 5522, 1632543, 5381679 So, if my assumptions are correct, and running out of PVs was the cause (I did get that message about increasing PMAP_SHPGPERPROC before I placed that in the kernel), there is a problem now. If you look at the vm.zone output, there are 84,410,445 PVs that could exist, but the system shows only 1,632,543 free. This leads me to believe there is another thing to tune. I already have a high PVs limit, but according to this output, it's not going further than 1,6 millions. My question is, what can I do to make the system use the full 84 millions, as I have not found any way to do this. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
suPHP - secure/reliable?
Hi all, I'd like to know your opinions on suPHP. I was looking for some software that would execute PHP scripts as the user who owns them, instead of www, and came up with that. But the site is written in poor english, the software consists on a root setuid binary, so I'm a bit worried about the quality of this software. Does anyone have anything to say about suPHP, either good or bad stuff ? I'd like your opinions. Regards, M.

6.0-BETA5, kismet & iwi ...
Hi list, I've just upgraded my laptop to 6.0-BETA5, hoping I finally would be able to have functional wireless.. things didn't go quite as I expected, tho. My wireless card is an Intel 2200BG, supported on FreeBSD by the iwi driver. I had it installed prior to upgrading by downloading from http://damien.bergamini.free.fr/ipw/ , but removed it and added device iwi to the 6.0 kernel instead. Now it always complains about "iwi0: Please load firmware." So, I went to damien's site again, only to find that the download link had been removed, and a reference to ports/net/iwi-firmware was there instead. I've tried to install the port, and it says I've already got iwi(4) support, and won't let install anything. I'm left with a iwi0 that has no firmware, an so is worthless. Is the firmware somewhere in the base 6.0 system ? The other problem is kismet. Looking at the (poor) kismet documentation, the best I could get from it was that I needed to define radiotap_bsd_x as my capture source on kismet.conf. The documentation isn't clear about what X is, so I've tried: - radiotap_bsd_x - radiotap_bsd_g - radiotap_fbsd_x - radiotap_fbsd_g Either way, it says the capture type is unknown. Then I tried with capture type ipw2200, and kismet said it wasn't built. So.. where is the iwi firmware or where can I download it (pkg_add -r iwi-firmware doesn't work btw), and how to make kismet happy about my iwi0 card ? Thanks in advance. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: FreeBSD 5.4 & Adaptec 2010s - raidutil / aaccli
Hi, I can't post exact messages now, but dmesg detects an asr "Adaptec Caching RAID", and the only disk detected (the RAID-10) is da0. As I mentioned, raidutil (from the asr utils package) keeps saying /dev/rdpti17 doesn't exist, and if I symlink asr0 -> rdpti17, the next time I run raidutil, it will erase the symlink. As I also mentioned, some posts from google mentioned symlinking /dev/rasr0 -> rdpti17, but I don't have such device. If you're talking about the SYSV-related kernel options, I have tried these and the error is the same. Chad Leigh -- Shire.Net LLC wrote: On Jul 16, 2005, at 10:45 AM, M.

If it says something with aac in it then you want the LINUX aaccli and if it says asr you want the asr utils, but you need to google on FreeBSD and asr as there is a kernel option you need for 5.4 to work with the asr utilities. For the aac device, you need to get the Linux aaccli program (much more advanced) and also load the linux_aac kernel module. I have both a 2200S (aac) working with 5.3 and a 2100S (asr) working with 5.4.

FreeBSD 5.4 CD and Adaptec 2010s controller w/ RAID 10
Hi list, I'm having a strange problem while trying to install FreeBSD on a pentium 4 server with an adaptec 2010s controller with a built RAID 10. It goes fine until it tries to read the CD (to install FreeBSD), at that point it starts spitting random numbers and letters in blocks, something like: cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 cc 99 cc aa dd 99 (letters/numbers are different) and it never stops. If I destroy the RAID 10, FreeBSD will boot up fine and detect all 4 disks.. if I insert a Windows CD, it will go to Windows the installation screen, which leads me to believe it is a problem related with FreeBSD and the fact that there is a RAID 10 created (remember, if I destroy the RAID it works fine and will go to sysinstall) This is my first RAID installation on a FreeBSD system, so I might be missing something obvious..

changing network card MAC address
Just set up a new box (5.4-RELEASE) as a home gateway and had to change the network card MAC address that does DHCP through the cable modem.
