HyperThreading
Hello, I'm running FreeBSD 7.2-RELEASE on a dual-core Xeon. It has a custom compiled SMP kernel, ACPI enabled, with the ULE scheduler. I've been looking into HyperThreading, and I've come to the conclusion that I should not use it. I've been told that HTT is disabled by default, however sysctl and dmesg seems to contradict that: CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2395.93-MHz 686-class CPU) Origin = GenuineIntel Id = 0xf29 Stepping = 9 Features=0xbfebfbffFPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE Features2=0x4400CNXT-ID,xTPR Logical CPUs per core: 2 FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP/HT): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP/HT): APIC ID: 3 cpu0: ACPI CPU on acpi0 cpu1: ACPI CPU on acpi0 cpu2: ACPI CPU on acpi0 cpu3: ACPI CPU on acpi0 SMP: AP CPU #2 Launched!

There is nothing in my loader.conf, sysctl.conf, or kernel config file related to hyperthreading.

Re: What is the highest hard drive read/write speed you were able to achieve by entire disk mirroring or striping?
I am seeing 85MB/s as a speed of a single Hitachi 1TB HD. How high can you go by mirroring or striping 2, 3, 4 harddrives? mirroring - the same, just with 2 processes reading both can get the bandwidth. make sure you use -s high enough (like 1048576) doing gmirror label stripping - the same, or 2,3,4 times, depends how you configure. for highest transfer and lowest concurrency (you mostly read huge files with one process) - use small stripe size. for lowest transfer (=1 disk) and highest concurency - use very huge stripe size like 512MB, so simply different process reading different things can hit different drives, but each I/O isn't spread. ___ 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

RE: Dump snapshot issue...
One thing you should try is to remove the dump_snapshot files, because they are supposed to be unlinked when the dump starts anyway, so they shouldn't be sticking around. Also, look for file flags on the directories, or ACLs, etc. And consider the permissions you're running dump with. Dump is running as root via cron / initiated by hand. ACLs not used. Have removed all existing dump_snapshot files, and have also removed and recreated all .snap directories. S'now working fine for all mountpoints, except /home... mksnap_ffs: Cannot create /home/.snap/dump_snapshot: Input/output error dump: Cannot create /home/.snap/dump_snapshot: No such file or directory It doesn't appear to proceed as normal either... as you can see below, it ends the previous dump, starts the /home dump, gets an I/O error, then proceeds straight to the /usr dump. The /home dump never gets performed. If I remove the -L option, everything goes thru fine, but complains about lack of -L flag... DUMP: DUMP IS DONE mksnap_ffs: Cannot create /home/.snap/dump_snapshot: Input/output error dump: Cannot create /home/.snap/dump_snapshot: No such file or directory DUMP: Date of this level 0 dump: Wed May 6 08:30:31 2009 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping snapshot of /dev/da0s1e (/usr) to standard output Fsck finds no errors on /home... point to note... mksnap_ffs CAN create /home/.snap/dump_snapshot as I'm sat looking at the file, however, once it's created it it's as tho it can't access it. The file is there, it wasn't before I ran the script. It's created it as root:operator, perms 400. I can open it in pico, add content to it, and save it happily. So I'm baffled!

reducing Windows Vista to install FreeBSD dual-boot
Hello, Maybe a bit off-topic (sorry for this). I've got a fresh Dell M4400 laptop with 250 GByte, pre-installed Vista on it. Is there a way to reduce the Vista to let's say 50 GByte and install FreeBSD -CURRENT in the remaining 200 GByte, just to have the Vista later for some investigations, or whatever? Thx If not I will scratch the Vista, install FreeBSD and later in the rest of 50 GByte the Vista again. matthias -- Matthias Apitz Manager Technical Support - OCLC GmbH Gruenwalder Weg 28g - 82041 Oberhaching - Germany t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e matthias.ap...@oclc.org - w http://www.oclc.org/ http://www.UnixArea.de/ People who hate Microsoft Windows use Linux but people who love UNIX use FreeBSD. ___ 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

I'm trying to build gcc43 on alpha 6.4.
In /usr/ports/lang/gcc43/Makefile I have:
# grep NOT_FOR_ARCHS /usr/ports/lang/gcc43/Makefile
NOT_FOR_ARCHS= alpha ia64 powerpc
#
In /etc/make.conf I have:
.if ${.CURDIR:M*/lang/gcc43*}
NOT_FOR_ARCHS= ia64
USE_GCC=4.3+
.endif
This used to work fine until some update. Not anymore.
The second setting is being used, i.e. the port is being built
with gcc43. But the NOT_FOR_ARCHS is not changed, so I have
to do it manually each time.
So I tried to experiment with changing variable values withing if-then.
many thanks

The amount that it will allow you to shrink will vary (probably depends on the fragmentation) but I guess you will be able to get 50G on a 200G disk.

Do I need both gcc-4.2 and gcc-4.3?

Any software you don't need you can safely remove provided it is not required by some other packages. Yes, only run dependencies are shown, therefore, from time to time I remove some packages which I don't need, and which were built only to build others, which I do need. HOwever, this is probably a waste of time, because it is likely that they would be build again at some point, when the other packages are updated. Also, I'm fairy certain, though check yourself, that all packages which require 4.2.5 would be also happy with higher version, i.e. I'd just leave the highest version of gcc. -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423 ___ 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

Any suggestion how I can fix that? With lots of small files, the time involved is far less dependent on the size of data, and much more dependent on the number of files, and the resultant number of directory entries that need to be updated. Lots isn't a particularly accurate count of the # of files, but if you're talking web cache files, I'll guess they average 5k each, which means you had 6 million files. df -i would have been more useful in the output above. This brings a number of questions up: * Are you _sure_ softupdates is enabled on that partition? That's going to make the biggest improvement in speed. * Are these 7200RPM disks or 15,000? Again, going to make a big difference. * If apache was still running, is it possible that it was creating enough disk activity to slow the activity down? Running top -m io will show you how much disk IO each process is creating. * When you compared the speed to your laptop, did you delete 6 million files from the laptop? If you deleted a single 30G file, then you're comparing apples to atom bombs. If this is a directory that you blow away on a regular schedule, you'd do much better to make it a dedicated partition and simply reformat it. -- Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/ ___ 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

Re: When a System Dies; Getting back in operation again.
... What is the best way to restore the full system? Can I use the FreeBSD installation disk in rescue mode? I experienced such a situation just 2 weeks ago. My primary problem was that I had to do restore over the network (no attached tape drives, no external HDDs). I wanted to use ssh to grab the dump from the backup server, but ended up using netcat which worked great. Here's basically what I did including backup from the not-yet-dead machine (note, I used intermediate backup server, but it should be possible to directly pipe dump to restore): 1. dump -0Laf - / | ssh backup-server cat dump.root 2. boot the new machine from CD disc1 (FreeBSD 7) or livefs disc (FreeBSD 7) 3. create and newfs partitions as explained in this thread (at least the size of backup, can be larger) 4. go into the rescue (fixit) mode, create mount points for created partitions (mkdir mnt.root), mount partitions (e.g. mount /dev/da0s1a /mnt.root), change directory to mount point (cd /mnt.root), configure NIC (ifconfig) 5. start netcat (nc -l 5 | restore -rvf -) 6. on backup-server: cat dump.root | nc new-machine 5 7. repeat for usr and var partitions Notes: 1. if security is an issue, ssh out from the new machine to the backup server with port forwarding (ssh -R 5:localhost:5 backup-server) and pipe the backup to localhost (cat dump.root | nc localhost 5); my initial idea was to start sshd in fixit mode (see my post to the list fixit console with sshd) which turned out to be too much of a trouble. 2. restore uses TMPDIR to store some temporary files during restore process; the fixit mode has limited free space and when it gets exhausted the restore process will fail, so it is a good idea to use an available partition as a temporary TMPDIR (e.g. export TMPDIR=/mnt.var while restoring usr partition and later use a subdirectory of usr as TMPDIR to restore var partition) 3. [IMPORTANT!] after the restore process is over, manually check restored etc/fstab and etc/rc.conf (currently mounted as /mnt.root/...) to fix: a) partition names (e.g. /dev/da0s1a might become /dev/amrd0s1a) b) ethernet interface names (e.g. em0 might become bge0) c) IP addresses in case you still have the old box running to avoid IP conflict You should now be able to safely reboot and log into your new machine.

So, at the moment I only have around 100 GByte for FreeBSD free, which is a lot, compared with other servers I have here.

You can get a trial version of PerfecDisk and you only need it once so that's not an issue:-) You have to do a system-files-defrag-on-next-boot (don't remember the exact options here)! \\anders I've done this a few times and the best procedure is to use the Parted magic CD and resize the partition.

RE: ReturnCode Checking for FTP
Can I assume you want return codes to know if the file was transferred correctly? Several years ago I was involved in architecting a middleware app for file/data exchange. For ftp delivery (and others) we'd check the file size locally, put the file, then check the file size on the remote side. Not fool-proof, such as CRC or Hash of somekind, but pretty good. Use bin mode for everything. Also, maybe as part of the file record itself you can embed a hash and have the client check this when processing the file on their end. Unfortunately when using ftp you never know what the ftp server supports, so unless you can dictate supported ftp servers, you can't get too fancy.

Based on your comments here, it really sounds like your devs need to implement some sort of cache cleaning algo into their code. If it's just deleting the oldest files, then you could probably run it far more frequently if you simply created a new cache directory each hour, and deleted the previous one. Honestly, I'm really confused -- if you can just throw away the cache each night, then why are you caching to begin with? If you just need temp files, why doesn't the app clean up its temp files when it's done with them?

Your only option is overriding in /usr/portslang/gcc43/Makefile.local. This is
because make.conf is read *before* the Makefile and the Makefile simply

Re: Assign IP address and hostname via kernel parameter
Hi, I would take a look at sysctl this system takes care of kernel parameters. There are a few man pages that delineate what is read only. I'm sure you are aware of setting the hostname at boot time.

Re: Repeatable X lockups
According to Jimmie James jimmie...@gmail.com on Sat, 05/02/09 at 15:46: When using the xv output driver for vlc or mplayer, X will lockup, crash instantly, trashing the screen and forcing a reboot Image of screen corruption: http://img.photobucket.com/albums/v287/jimmiejaz/xcrash.jpg This just started manifesting in the past week or so. I have experienced the same problem, but I didn't see any suggestions or answers to your posting. Have you had any success yet with this? Have you tried any other output drivers? This is something I plan to try in the next few days. My system is i386 with Intel 915 graphics on the motherboard. Xorg 7.4 runs fine. When I run mplayer from the command line, in an xterm under open-motif, the X Windows session dies and I am tossed back to the vty. When I similarly run vlc from the command line, the screen is locked in an even worse state than your above URL. I am forced to ssh(1) in from another FreeBSD workstation to reboot. Before the reboot, ps(1) reports no processes running xorg or any of its child processes, it seems as if my video hardware has been left in some ugly, locked-up, unusable state. What is interesting to me is that the same flash file that causes vlc and mplayer to crash runs just fine in ffplay(1) (part of ffmpeg port). Yet at least vlc uses ffmpeg, while it doesn't look like mplayer does. This is 7.2-PRERELEASE built on 24 Apr 2009 with the ports of mplayer and vlc built on 2 May 2009 following a csup(1) of complete ports tree on either 24 Apr or 25 Apr - so approximately the same timeframe as you.

Alternatively, you could assign a dedicated filesystem for the cache and when cleaning up: * stop the app (or disable caching), * umount * newfs * mount * restart the app (or reenable caching). newfs is MUCH faster than manually deleting gazillions of files. If you don't like the (small) downtime during newfs, you could also play with two or more dedicated filesystems, and rotate between them (though that would be a waste of disk space).

Autofs howto
I'm going to take another stab at this. I'm wondering if I can use autofs on FreeBSD. Last time I asked the question someone said I need amd, which I found rather cryptic. I later discovered that there is a amd-utils in ports and an amd directory in contrib under source. So, is amd a kernel module? A separate program I compile? Should I build the ports amd-util instead? Will that give me autofs functionality? I've searched the web for howtos, but they all seem to be for LInux, not FreeBSD. It even seems the latest stuff for amd on FSBD is for 6.1. (I just upgraded to 7.2 STABLE today.) Has anyone ever done this?

My objective would be to create another up to date MySQL jail and when I'm ready to make the switch, just point the new jail to the data outside the jail using something like a nullfs mount.

Re: Advices for a jailed MySQL server
In response to Martin Turgeon free...@optiksecurite.com: Hi everyone, I'm starting to build a new dedicated MySQL server. I will be using FreeBSD 7.2-REL. My plan is to jail the latest version of MySQL 5.0 and to put the MySQL data outside the jail. My objective is to be able to update MySQL without down time. My objective would be to create another up to date MySQL jail and when I'm ready to make the switch, just point the new jail to the data outside the jail using something like a nullfs mount. Is someone using something like this? Did someone have any advice about how to update a MySQL server without down time? Did someone have any advice on how to tune a dedicated MySQL server running FreeBSD 7.2 (Dual core Xeon, 4G RAM, mirror RAID on a PERC5 controler 2x146G 15K)? Thanks everyone for sharing your precious knowledge :) I expect that what you're trying to do will work, however it's horrifically error-prone during the upgrade procedure (what if you forget to stop the first MySQL before you start the new one!) If you need to do anything zero-downtime, then you probably want to run multiple MySQL instances and use database replication to keep the data in sync. That way you just switch which DB is master, then upgrade the slave ... rinse/repeat. -- Bill Moran http://www.potentialtech.com http://people.collaborativefusion.com/~wmoran/ ___ 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

Myths about Power Over Ethernet
Myths about Power Over Ethernet May 5, 2008 Power-over-Ethernet (PoE) technology integrates power and data across standard Cat5/5e/6 network cabling and provides more flexibility in today’s workplace. PoE enables power to be supplied to network devices, such as IP phones, network cameras, and wireless access points through a single, most often existing, network cable. When combined with an uninterruptable power supply (UPS) a PoE network delivers continuous operation and minimizes business downtime by eliminating most power interruptions. With the ability to install endpoints in any location PoE technology provides a scalable and flexible networking infrastructure geared for growth and efficiency. PoE Switches can provide all the power I need or will need. Today most switches are merely PoE-enabled. This means the majority rely on power management to share available power across the switch ports. The switches are designed with a smaller power supply that is typically capable of powering the switch itself and providing the required 15.4 watts of power over a limited number of ports. For example: A 24-port PoE Switch with power management typically has a 195-watt power supply. After the 40 watts needed to power the switch, you have approximately 155 watts remaining. If 12 of the 24 ports are used to connect end devices using 11.5 watts each, you would only have 17 watts remaining to provide power on the last 12 ports. The math doesn’t match the ports: 195W – 40W (switch) – 138 (12 devices @ 11.5W/ea) = 17W left for power on 12 ports Myth Busted: A PoE Switch is often not the best and most cost effective solution. A midspan and a PoE switch are the same. A PoE Midspan is not a switch. A Midspan is an additional PoE power source that can be used to offer full power to all endpoint devices. PoE Midspans (Power Hub or Power Injector) pass data from a switch and ‘inject’ safe power acting as a patch panel of sorts. Midspans are commonly used with either a non-PoE switch, an existing PoE switch, or a new PoE switch in a network. In addition to offering full power across all available ports, midspans costs substantially less per port and overall than a new PoE enabled switch. Myth Busted: Midspans do not switch – they make use of existing best-in-class switches. They inject safe power across all ports and cost less than PoE switches. . Only a switch that has PoE built in should be used to power devices like IP Phones, Access Points, and IP Security Cameras. Switches were designed to, well, switch. PoE Switches are designed with power management and have to distribute different power as required to ports but there is often not enough power for all devices plus the power required to complete the primary task - switching. Networks that have multiple devices like IP phones, IP cameras, wireless access points quickly go beyond the limited capacity of managed power PoE switches. As more PoE devices continue to grow in capabilities and market share this managed power limitation will become more and more evident. Midspans, in contrast to switches, were designed to provide full power on every port and deliver safe and reliable power based on the industry standards (IEEE802.3af/at). Myth Busted: Rather than relying on power management in a switch use a midspan that can deliver full power (15.4W) to every port for all PoE-enabled devices now and in the future. Ethernet devices not PoE-enabled (non 802.3af/at compliant) cannot be powered using PoE technology. Many devices do not directly accept Power-over-Ethernet but can still use PoE technology. If the device uses less than 12.5 watts (802.3af) or less than 50 watts (802.3at+) and connects to an IP Ethernet network you can use a PoE splitter. PoE splitters enable you to accept PoE power from any IEEE 802.3af/at compliant switch or midspan then separates the data and power on to two seprate cables. The data is connected to the end device through a standard RJ45 plug while the power is connected using a standard 5.5 x 2.1 x 12mm Adapter Plug. Splitters can also convert the input voltage to the required voltage for a non-PoE device. Splitters are traditionally used with older network products which only accept power through their (DC) jack and data through their RJ-45 jack. Myth Busted: PoE splitters can be used in conjunction with PoE midspans and switches to provide both the data connectivity and power required by most endpoint devices. I need/will need additional PoE switch ports to power my IP cameras and high-power pan, tilt, and zoom (PTZ) cameras. Today, many devices have evolved into more advanced solutions with higher power requirements. The traditional approach was to endure a “forklift upgrade”. This meant buying new PoE switches at considerable cost and physically swapping out the existing switches to meet higher power requirements or add more powered ports.

The giveaway is his suggestion that following his advice would make FreeBSD a best seller. This reflects a complete lack of awareness of what FreeBSD is all about. Setting aside the fact that FreeBSD is not a commercial product and thus has nothing to sell, he also presumes that our primary goal is to increase the size of our userbase and that we are willing to make whatever accommodations are necessary to achieve that goal. But unless I'm mistaken, that isn't FreeBSD's goal. FreeBSD's goal is to provide a freely-available implementation of BSD Unix for the most common hardware. New users who are looking for a BSD Unix are welcome, but they are expected to adapt to FreeBSD's way of doing things and not vice versa. The current userbase is large enough to suggest that many people have no problem with those terms. As for the suggestion that what FreeBSD needs is VB, there have already been various ports of Basic over the years. None of them seem to have had much success. BSD users seem to be content with traditional shell scripting, perl, or newer scripting languages like python -- all of which better reflect the Unix philosophy than VB does. ___ 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

What make is in 7.1?
When I do man make I get a man page and it includes references to the pmake tutorial which seems to be basis of an HTMLize pmake tutorial in one of the books. But clearly the installed make is not the pmake described in the tutorial. The tutorial frequently suggest using Pmake -h for more details about particular points. But in 7.1 make -h results in an illegal option message. There is no pmake or Pmake. There is a pmake port but it won't build in 7.1. So it seems I have a lot of documentation for pmake, which clearly I don't have and can't get.

unable to boot with Nvidia AGP graphics card
Hi all, Recently my PCI graphics card failed on my Dell Dimension 4100. I replaced it with a known good card I had lying around: an Nvidia GeForce 3 TI200 with an AGP interface. My FreeBSD installation will not boot with this graphics card. The boot loader hangs at the twirling baton as follows: /boot/kernel/acpi.ko text=0x43698 data=0x23c0+0x10f0 syms=[0x4+0x7ba0+0x4+0xa828] \ I'm running 7.1-RELEASE generic kernel. Anyone ever see anything like this before? Any ideas on how I can debug? Is there anything I can do with the loader prompt to see what is happening when this occurs? The keyboard still seems responsive when this happens (the caps-lock, num-lock, etc. still work). It is almost as if the boot loader is unsure how to send output to the AGP bus. I have tweaked every possible setting in the very limited BIOS but nothing helps. BTW, I know that my hardware is good because this is a dual boot system and I am able to boot into Windows just fine. I am also able to run Linux from a live cd. However, I also tried a FreeBSD install disk and it hangs at the same place.

Java without CUPS
Hello list, I know that, since my printer speaks Postscript, I don't need CUPS. But some of the ports I'm installing want to install CUPS as a dependency. The first one I happened across was java/jdk16, but I'd be surprised if there weren't more. Could it be as simple as # make -DWITHOUT_CUPS install ? I see no such possibility in either the config options or the Makefile for jdk16, and google was no help. It's not like the disk space costs anything nowadays, but I chafe at installing unneccesary bloat on my system. If it can't be done I'll deal, but I'd like to stay CUPS-free if possible.

Re: filesystem: 12h to delete 32GB of data
Sorry. This statement is incorrect. If you aren't using ZFS, or even a GEOM volume with mirror/RAID5/softup/etc, you cannot make the statement that hardware RAID is faster. I learned that 3 years ago. It takes about 30 minutes to mirror 1.5TB on ZFS. Try that on hardware RAID. I did the same with 80 GB SATA drives a couple of years ago. Gmirror killed hardware mirror by 50% When your processor on your hardware RAID card is junk and you have a kickass processor and good chunk of memory on your main system and decent controller that isn't getting maxed, the hardware RAID is always faster paradigm walked out the door a few years ago. This does not go for EMC, IBM, Hitachi high-end storage arrays where you write to TBs of RAM Cache. P.

Just as an information: Gimp (Gutenprint) installs CUPS, allthough
I already have apsfilter (HP Laserjet 4000 PCL). When printing,
Gimp still tries to connect to server (lpstat).
Could it be as simple as
# make -DWITHOUT_CUPS install

I don't think it is possible. The Makefile lists CUPS as a build
dependency (UILD_DEPENDS):
% grep -n cups /usr/ports/java/jdk16Makefile
24: ${LOCALBASE}/include/cups/cups.h:${PORTSDIR}/print/cups-base
But I think it's possible to delete CUPS from the system after
JDK is compiled successfully: CUPS isn't listed in RUN_DEPENDS
so it doesn't seem to be required for running JDK / Java.

installing unneccesary bloat on my system. If it can't be done I'll

Same here, too. :-) Philosophy behind the idea: I don't want to
install software that I don't need / don't run.

How to get the user time of another running process on FreeBSD?
Hi, I would like to know how I can get the user time of another running process on FreeBSD? Ideally I would like to find a solution that would work as well on other *nix systems. So far the solutions I have found are specific to a given OS (format of proc filesystem, lock_getcpuclockid)... Thank you!

Hope you have some guides out there -- Med Venlig Hilsen Kalle R. Møller It will vary per person. It will vary by said person's workload. But I tend to use a couple of basic principles. 1) NEVER let your system lapse to End of Life. a) it's easier now that freebsd-update exists and is part of base. b) reading the impact section in the security announcements that are mailed to you, and if they affect you, perform the update immediately... not ASAP 2) Install portaudit and watch the periodic mailings that are sent to you. They list vulnerabilities in ports that really should be addressed. Knowing that for each notification portaudit sends to you, it WILL affect some service. Schedule the update ASAP, but I never let it go past a week. The outline above is my own view, I don't expect anyone to share them, I don't mind if they inherit them. So you want to know when to update the ports tree? when a vulnerability exists and an updated/patched version of the port is then in the ports tree. portaudit gets fresh databsae updates, and rescans your ports at each run of the periodic script. Portaudit itself doesn't care about what version the ports tree has, it cares about the version you have installed on your box. I dislike automation -- when something is automated and it fails, how disastrous can it be? What is missing, due to a failed automation? Last night my backup script at work didn't backup anything. An unused tape was reported as available, yet the backup didn't run. I had no backups to work off of. This script worked fine for the past 3 months, why fail now? Because of this, even if it IS more work, I tend to do things by hand. Less risk, IMHO.

Re: Autofs howto
Paul Schmehl wrote:
I'm wondering if I can use autofs on FreeBSD. Last time I asked the
question someone said I need amd, which I found rather cryptic.
Indeed it is cryptic, let me gave an example which works:
niobe% cat /etc/amd.conf
[global]
auto_dir= /.amd
log_file= /var/log/amd.log
log_options = error,fatal,user
map_type= file
search_path = /etc
[/Cd]
map_name= amd.cdrom
# For nfs mounts
[/Net]
map_name= amd.net
niobe% cat /etc/amd.cdrom
cdrom type:=cdfs;opts:=ro,nosuid;dev:=/dev/acd0;fs:=${autodir}/cdrom
niobe% cat /etc/amd.net
/defaults type:=host;fs:=${autodir}/${rhost};rhost:=${key}
* opts:=rw,grpid,resvport,nosuid,nodev,soft
Now some comments. I use amd without options so it just uses
/etc/amd.conf to configure itself. When you try to access /Cd
it uses the configuration in /etc/amd.cdrom, and if you try to access
/Net it uses the configuration in /etc/amd.net.
Finally if you try to access /Net/ada for example, the key is ada, and
so is the remote host. It is queried for NFS mounts and everything is
mounted. After
niobe% cd /Net/ada
i have:
niobe% df
...
ada:/ada36196652 26972064 735623279% /.amd/ada/ada
ada:/ada1 287391356 246682696 2610999690% /.amd/ada/ada1
ada:/ada2 288362876 180649856 9306495666% /.amd/ada/ada2
ada:/ada3 99188500 80794628 1327396086% /.amd/ada/ada3
ada:/adm36204684 1682772 32653156 5% /.amd/ada/adm
Note that autodir is /.amd and fs is ${autodir}/${rhost} as you can
see.
Getting out of /Net/ada those mounts are unmounted.
I hope this helps explaining some of the mysteries of amd.
