If this is a dedicated web server, you sure are configuring it wrong. First off, you tell it to start 8 workers, then immediately kill off three of them to meet the MaxSpareServers. That's pretty minor, however, as it only happens at startup. MaxSpareServers of 5 is pretty low for a busy webserver. If the site is seeing a lot of traffic, or the traffic is erratic, you're forcing Apache to try to constantly tune itself to exactly what the load is. If this server is dedicated to webserving, you'd do better to raise MaxSpareServers to something like 25, so you have some spare capacity when the load spikes instead of forcing Apache to do a lot of forking, then kill off a lot of processes, then fork a lot of them again ...

Re: (6.2 install) Offering both install ISO's via nfs?
At Wed, 17 Jan 2007 it looks like Garrett Cooper composed: On Jan 16, 2007, at 10:43 PM, Bill-Schoolcraft wrote: Hello Family, Hmm, in doing installs with more than one install iso (disk-1 and disk-2) via NFS I'm not clear on the instructions where it states to simply copy the FreeBSD distribution files... (question) (A) Would that mean to copy the files from both install disks into one common directory then export the directory via NFS? Yes. That's the purpose of NFS installs. Directory heirachy (from the release's directory), needs to be maintained though. So the base directory would be similar to what's seen in ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386, where you'd have to create a directory name that matches the release, then download all the items to your subdirectory on the NFS share under the release directory that you want to install (i.e. 6.2-RELEASE/base, etc). Many people would just download their files from the FTP site and copy it to their NFS share as I described above. That's what the handbook means AFAIK. Thanks Garrett, Now, just to confirm one thing... On my NFS server I now have an exported directory called: /mnt/6.2-RELEASE Inside of that directory I have the full contents (not an iso image) of the first install disk of FreeBSD-6.2, so far so good? Now, for the remaining data on disk-2, which has a duplicate file like disk-1 has called: cdrom.inf and a duplicate directory like disk-1 called: packages I figured I can rsync the second CD's contents of /packages into the main tree but what about the conflicting two files both named cdrom.inf ? Will the installer be intuitive enough to not prompt for second CD when looking for files that would normally reside there? The reason I say that is that if one chooses to install, let's say, mtools or the linux software out of emulators on the main menu you put in the 2nd disk, it intuitively tells you that the packages are not on disk-2, but disk-1. So I'm thinking there is some residual metadata that not only has the package name but the CD disk location appended to in. Similar to the disk shuffling one had to to before when ejecting and injecting multiple CD's for previous installs on lets say 6.0 or 6.1 Thanks again Garrett (B) Mount each ISO in a loopback then export the two loopbacked ISO's under each other in an exported parent directory? TIA Not possible with the basic FreeBSD installer disk, but maybe it's possible with the FreeBSIE LiveCD, or a custom CD if you build in the relevant stuff for a rescue shell; you'd still need to get at the iso somehow though, and you'd have to make sure that ramdisk (that's the Linux name, but I forgot the FreeBSD name right now?) support in order to mount an ISO image compiled into your kernel. snip -Garrett ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] -- Bill Schoolcraft * http://wiliweld.com ~ Unix is very simple, but it takes a genius to understand the simplicity.

Thanks for your reply, I repeatedly copied a 700MB file from one harddrive to the Raid 5 Drive, a different file every time so caching won't be a large factor and consistantly got 8-9MB/s.

Keep in mind that by simply copying, you are testing the speed of the OS cache, the speed of the filesystem, and the speed of the driver all at once. We're going to have to narrow it down to isolate the problem. I can give you advice in FreeBSD, but I don't know how to do it in Windows.

(6.2 install) Offering both install ISO's via nfs?

(question) (A) Would that mean to copy the files from both install disks into one common directory then export the directory via NFS? (B) Mount each ISO in a loopback then export the two loopbacked ISO's under each other in an exported parent directory? TIA # 2.13.6.1 Before Installing via NFS The NFS installation is fairly straight-forward. Simply copy the FreeBSD distribution files you want onto an NFS server and then point the NFS media selection at it. If this server supports only “privileged port” (as is generally the default for Sun workstations), you will need to set the option NFS Secure in the Options menu before installation can proceed. If you have a poor quality Ethernet card which suffers from very slow transfer rates, you may also wish to toggle the NFS Slow flag. In order for NFS installation to work, the server must support subdir mounts, for example, if your FreeBSD 6.1 distribution directory lives on: ziggy:/usr/archive/stuff/FreeBSD, then ziggy will have to allow the direct mounting of /usr/archive/stuff/FreeBSD, not just /usr or /usr/archive/stuff. In FreeBSD's /etc/exports file, this is controlled by the -alldirs options. Other NFS servers may have different conventions. If you are getting “permission denied” messages from the server, then it is likely that you do not have this enabled properly. # It seems to be written for the time when there was only a single ISO cd. -- Bill Schoolcraft * http://wiliweld.com ~ Unix is very simple, but it takes a genius to understand the simplicity.

Re: Mystery Spam Piling Up in Mqueue
In response to Jeff Royle [EMAIL PROTECTED]:
The example below is simply a bounce that did not go through.
Note: Mailer-Daemon and MDeferred: Connection refused by macbilling.com.
Your system attempted to delivery a bounce back to macbilling.com and
the MTA @ macbilling.com is rejecting the bounce.
Most likely spam using a forged (or real) address
something@macbilling.com was sent to your system to
somefakeaddress@highperformance.net and of course your system could
not deliver the message so it bounced.
As another idea, if these are being generated as a result of spam sent
to non-existent addresses, you can eliminate that particular source by
reconfiguring your MTA to reject unknown addresses instead of bouncing
them. This may be a simple configuration parameter, or it may involved
replicating the user list from one machine to another, depending on your
setup.

You're using the 32-bit version, right? The design of x86 architecture (i.e. it's not FreeBSD's problem) is such that a part of memory addresses needs to be set aside for hardware uses, such as the PCI bus, AGP memory others. This manifests as holes in memory that are not accessible to OS. There are two possible solutions: you may try compiling a 32-bit kernel with PAE (but not all drivers support PAE), or install the 64-bit version of FreeBSD. Well I hate when people say this, but I'm going to say it.. :) When I did a default install of ubuntu, it saw all 4 gigs without a hitch. So does that mean it already includes PAE, or something else ? One of those two. You sure you didn't install a 64-bit version of Ubuntu? Aside, I will read up on PAE. I'll read up about 64 bit as well, I've been hesitant to make the jump only cause any word of mouth i've heard said that it's not ready for production. Maybe that's off base, it's only what i've heard We're deploying a lot of 64 bit stuff around here. Our experience has been that the OS is as solid on amd64 as it is on i386. Server applications are the same. There are, however, a lot of desktop applications that are still flaky on 64-bit -- mostly non-mainstream ones.

Re: stopping my server from spamming
In response to David Banning [EMAIL PROTECTED]: This is more of a question geared towards your mail server application than FreeBSD. You should check your mail logs. If you want better advise, you may want to provide more information on what mail server are you running, and what did you do to prevent SMTP relay. I am using sendmail. It will not allow open relaying. What I would like to know is how I can separate legitimate emails in the log from spam. All that appears is the from: email and the to:email. Look at one of the spam emails and review the headers to see how it's getting delivered. In the past I have seen separate SMTP servers installed by viruses on windows boxes which are spamming away -independent- of sendmail. I have blocked port 25 from all my connected windows boxes, but will that take care of it? Who knows. You first have to determine how the problem is occurring. The block you've implemented is a good idea -- I think everyone should do it as a matter of course, but there's no guarantee that it will fix your particular problem until you know what that problem is. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I am facing a motherboard/CPU upgrade following the demise of an Athlon+ setup. (I am running my FreeBSD drive in a P3 while trying to figure this out.) Replacing it with an oldish P4 would be easiest but they are rapidly becoming extinct. After much Googling I can't quite figure out what happens if I were to put the FreeBSD i386 HD into a 64-bit system. Nothing? Disaster? Do I totally have the wrong end of the stick? I'd be grateful for any advice. Since the AMD64 architecture is completely backwards-compatible with the older i386 architecture, the i386 version of FreeBSD should work just fine in the new system. Thanks very much for this. I have the impression from scanning the freebsd-amd64 archives that it is difficult to convert an existing system from i386 to AMD64, and probably not worth it. Do people have any opinions on this? Depends on your need. I've never upgraded from i386 to amd64, so I can't say what the process is like. If you're running a desktop system, I recommend against running amd64. A lot of desktop code burns down, falls over, then sinks into the swamp when run on amd64. If you're running a server, not much problem. Most serious server programs have been running on 64-bit systems since before amd64 existed. One workaround is that you can run i386 programs on an amd64 kernel, if you compile with a special kernel option. I have no actual experience with this to comment on how well it works. Except for some very specific workloads, CPUs tend to perform roughly equally when run in i386 mode vs. amd64 mode. The only majorly compelling argument for amd64 at this time is that it makes life much easier if you have more than 3.5G of RAM in your system. In i386 mode, you either need to compile your kernel with PAE (which is an ugly, poorly supported hack in my opinion) or give up the RAM over 3.5G. -Bill ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Restarting is buggy as well, with the same symptoms. My (inelegant) solution is to install a pair of ethernet managed power strips, so I can kill power remotely to bring it all the way down if need be. We get all our units with Dell's remote access card installed. It gives us the same kind of remote admin -- equivalent to being able to hit the power button from the other side of the planet.

Re: Shar question
In response to Beech Rintoul [EMAIL PROTECTED]: I'm trying to learn how to use shar. I've read the manual. If I pass a directory to shar: shar foo foo.shar Results in a shar file. Problem is that when I unpack it I just end up with an empty directory. I probably need to pass it a flag or something, but I'm not sure which one to use. How do I make a shar file out of a directory and ALL it's contents. shar needs to know all the files it's to put into the archive, it doesn't walk the tree for you. Thus you could do: share file1.txt file2.txt file3.txt archive.shar to selectively grab only the specified files. When grabbing an entire directory tree, you can use the syntax: share `find \start\of\directory\tree -print` archive.shar which is hinted at in the man page. The backticks cause the find command to be executed, and the output of find is given to shar. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Dummynet fragmenting packets
In response to Mike Murphree [EMAIL PROTECTED]: Having an issue on a 5.3 system using ipfw and dummynet to create a bandwidth limited and large latency pipe for a mpeg video stream. If I pass the packets between the two NICs without routing through a dummynet pipe, it's fine. If I route it through a pipe, it's fragmenting each packet (client requested 1468 byte packets) into two packets, the second packet with an offset of 1440 bytes. Does anyone have any idea why it's doing this, and have a solution to this problem? As a general rule, fragmenting occurs when packets move between different networks with different MTUs. I.e. the originating network has a larger MTU, so the packet must be broken up in order to pass it on to the network with the smaller MTU. Now that that's out of the way, I can see 3 possibilities as to why dummynet is fragmenting packets: 1) Dummynet has the wrong information about what the MTUs are on your networks and is fragmenting the packets needlessly. 2) Dummynet is altering the packets, they become larger and then no longer fit in the MTU. 3) The endpoints are doing path-MTU-discovery, but when you put dummynet between them you somehow break PMTUD. To narrow this down, you'll need to determine what the MTUs are on each network and whether they're being respected, is the total size of the reassembled fragments the same as when the packet came in, and whether or not PMTUD is in use, and whether something in dummynet or any related filtering rules is breaking it. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have a FreeBSD 6.1 firewall/router in between the cable modem and the switch to other nodes. My question is how could I add static routes to say my web server having an external IP address but still going through the firewall box? NAT is not an option.

The other option is to set that system up as a router, and build a proper routing table. Your ISP will need to be involved so they know to route traffic to your subnet through your gateway system. You need to enable forwarding in /etc/rc.conf. Then you'll need to subnet your range properly. Something like: 70.164.48.225/29 - external 70.164.48.241/29 - internal Then set your external interface on the router to 70.164.48.226 and the internal interface to 70.164.48.242. They you can use 70.164.48.243 - 249 on the inside. Configuring the FreeBSD machine as a bridging firewall will simplify the process, however, and is the approach I would recommend. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: Soft Updates Help
Sean Murphy [EMAIL PROTECTED] wrote: I have read up on soft updates and have some questions. The way that I am understanding soft updates purpose is to allow file systems to be mounted dirty after an unclean shutdown of the system. That's not the purpose. The purpose is to improve performance by taking advantage of delayed writes much the way an asynchronous filesystem does, while preventing horrendous data corruption by ordering those writes, much the way a journalling filesystem does. The fact that you can generate filesystem snapshots is a side-benefit. The fact that you can use filesystem snapshots to validate the filesystem after it's been mounted is a further side-benefit. If this is a safe way to restore consistency why is it not used on /? Because writes are delayed, it's possible for data to be lost in the event of a crash -- it acts like a database, either the entire transaction is committed or it's rolled back, either way, the data is guaranteed not to be corrupt. Also, on heavily used filesystems, softupdates can lead to the filesystem temporarily having less space available than it really does. I.e. you update /kernel, softupdates completely replaces the file with a new one, but the blocks for the old file haven't been reclaimed yet. For a short period, you might have 1 kernel file, but there's 2x that being allocated for it. For these two reasons, / is traditionally _not_ mounted with softupdates enabled, since it's critical to system startup. If a file system is not heavily written to is it better not to use soft updates? Weigh the good vs. the bad: *) synchronous mounted filesystem is almost guaranteed to keep your data safe at all times, but is abysmally slow. *) softupdates _may_ lose some data if your system crashes before all writes are flushed, but will never _corrupt_ it. Additionally, you get a LOT better speed. *) Asynchronous is a little faster than softupdates, but it's damn near guaranteed to be corrupt in the event of a crash. When file systems are mounted dirty and our being used while the backgound fsck is running on the file systems how does it prevent files from being lost? It doesn't. It guarantees that your filesystem will always be mountable and never corrupt, but it doesn't guarantee against data loss. Here's a simplified example: Let's say you're saving a big file and the power goes out. When the power comes back on, there are basically 3 states that file can be in: A) It was fully written to disk -- you got lucky. B) Nothing had been written to disk yet -- data loss C) It was partially written to disk -- your filesystem is corrupt, you either need to allow a filesystem repair program to fix it (fsck -- or chkdsk on Windows, for example) or you'll have weird problems with it until you do so. Softupdates guarantees against C. It does this by (essentially) writing the file backwards: 1) it writes all the data to data blocks, and once that's done 2) _then_ it creates a directory entry for the file. If the system crashes between #1 and #2, it looks like B happened, but you never get in scenario C where the filesystem is corrupt and gets more corrupt as you continue to use it. Instead, when fsck runs (in the background) it realizes that there are data blocks in use that don't belong to any file, and it can free them up for the filesystem to use. That's somewhat simplified, but it gives you the basic idea.

Re: stop a freebsd server from responding to pinging?
In response to Wasp King [EMAIL PROTECTED]:
1. How do I stop others from port scanning a server?
Drive to their house and smash their computer.
2. is stopping the response to pinging enough?
No. In fact, not responding to ping is a bad idea. Disabling ping
responses violates certain RFCs and is a tactic taken by sysadmins
who should know better.
Additionally, a determined scanner won't care whether you respond to
ping or not, so it doesn't even gain you anything. nmap, probably
the most popular scanner out there, has an option to scan without
pinging, and even _recommends_ turning that on if you try to ping
and get no responses.
3. how to do I stop the server from responding to
pinging?
You can always use pf or ipfw, if you _really_ want to go down that
road.
Running FreeBSD 4.2 and 6.1.
I changed the /etc/rc.network file to NO for
broadcast ping responses, and this did not work (still
responding to ping) when I rebooted:
case ${icmp_bmcastecho} in
[Yy][Ee][Ss])
echo -n ' broadcast ping responses=NO'
sysctl net.inet.icmp.bmcastecho=1
/dev/null
That just stops it from responding to ping requests destine for the
broadcast address, which is a topic of some debate. It will still
respond to ping requests sent directly to it.
Anyway, the question that you didn't ask is how do I secure my system
from network attacks. The QD answer is:
1) only run network services that you really need
2) ensure those services are properly secured
If you do those two, who cares if you get portscanned?

Re: Does disk encryption causes a performance penalty for Data Access/Read/Write, etc
In response to VeeJay [EMAIL PROTECTED]: Does *disk encryption* causes a *performance* penalty for Data Access/Read/Write, etc? Any kind of encryption causes a performance penalty. However, if your CPU is powerful enough, it's possible (even likely) that the CPU is still able to encrypt faster than the disk can write the data. The result would be that you won't notice the penalty unless you've got other CPU-intensive tasks running that reduce the amount of CPU available to the encryption process.

Re: IPFW NFS
In response to vittorio [EMAIL PROTECTED]: I have two FreeBSD 6.1 boxes one of which (IP 10.0.0.1) is an NFS server and the other one (IP 10.0.0.2) is, among other things, an NFS client sharing directories with the NFS server. It all works correctly and I can mount_nfs all the directories from the server. BUT, I'm now trying to use an IPFW firewall both on the server and on the client. My simple aim is to setup connections between the 10.0.0.1 server and the 10.0.0.2 client ** only **; no connections should be possible with other clients! Now I've tried the poor documentation I could find googling with the keywords freebsd ipfw nfs to no avail, I cannot mount_nfs any share on te client because something goes wrong with RPC. Concentrating on the client side (no ipfw for the moment on teh server) I tried the following NFS is difficult to firewall, as it's not guaranteed to use the same ports all the time. The NFS server has options to restrict who can connect, see the man page for exports. Othwerwise, Chuck's advice was good. Additionally, you can debug IPFW using 'ipfw show', and by inserting log statements into your ruleset to get more useful feedback. -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Bill you just letting it scroll on the terminal, or redirecting it to a file?
Just redirected to a file. FFS, soft updates, 7200 rpm SATA drive
with the disk's write cache turned off. Input data rate is less
than 20 M bits/sec. I can write to the disk at approx 6 M Bytes/sec
sustained. (or 10x that with disk write cache turned on, but
I don't like trashed filesystems after the machine goes down hard)
The machine and the disk are plenty fast enough, AMD64, 2 GB main memory.
CPU is 90-something percent idle.
Sometimes it works fine for extended periods, 30-40 minutes. Other times
the src box reports thousands of network errors. So far I haven't figured
out what the difference is between the working tests and the failing tests.
The crontab directory is empty, so it shouldn't be cron jobs.
As an experiment, try running the process and redirecting
stdout to /dev/null -- if it doesn't exhibit the problem, then you
need to look at where you're actually storing the data and speed that
part up.
I've thought of trying /dev/null but haven't yet. It might provide
a clue.
I would expect that the filesystem should be buffering the write
from short term disk latency. Surely FreeBSD 6.0 provides the
classic Unix write-behind?
The disk activity LED flashes constantly, so it doesn't appear to be
saving up disk writes and then doing a bunch at once,
Is the data coming in at a fairly constant rate?
Yes.
you've got plenty of RAM
The machine has 2 GB. I wonder if the process is getting its fair share?
I have been observing other problems where disk activity to one disk
will make an unrelated process reading data from a different disk *very*
unresponsive.
Sounds like a hardware problem to me. If you've got a crappy SATA
controller that's going to block every now and again, you're going to
have trouble with this.
It's not something impossible to work around. I get the impression that
this machine is doing little or nothing other than receiving this data.
If that's that case, you can use the entire 2G for buffering, and store
incomming data until the disk starts responding again. I don't know
off the top of my head, but I seriously doubt if the OS is going to use
2G to buffer disk writes. You, however, can. As your program stands,
it will buffer a maximum of 15000 bytes, but you're using blocking IO,
so that doesn't even help you if the write blocks. If you want to take
advantage of all that RAM, you'll have to add some complexity to your
program. The following is roughed out, not tested (may contain fenceposts)
but liable to work once you fill in the blanks (although it's lacking any
error checking) Start by making BUFFER_SIZE _much_ larger -- several megs
at least, or even bigger if this machine is dedicated to this task:
[...]
/* Set stdout to non-blocking */
fnctl(1, O_NONBLOCK);
startread = startwrite = buffer;
while (1) {
/* Wrap around if we're at the end of the buffer */
if (startread == buffer + BUFFER_SIZE) {
startread = buffer;
}
/* Find out how much unused space is currently in the buffer */
if (startwrite = startread) {
avail_buffer = BUFFER_SIZE - startwrite;
} else {
avail_buffer = startread - startwrite;
}
/* Read in as much as possible */
num_read = read(fd2, startwrite, avail_buffer);
/* move the write pointer */
startwrite += num_read;
/* Wrap around if we're at the end of the buffer */
if (startwrite == buffer + BUFFER_SIZE) {
startwrite = buffer;
}
/* Calculate how many bytes we have to write */
if (startwrite = startread) {
readytowrite = startwrite - startread;
} else {
readytowrite = BUFFER_SIZE - startwrite;
}
/* Here is the key ... this only works if descriptor 1 is
* non-blocking ... otherwise your code will wait here until
* all the bytes are written ... you don't want that
*/
num_written = write(1, startwrite, readytowrite);
startwrite += num_written;

At one point during this test, the bsd machine is slowly falling behind, as shown in the smaller and smaller window size.

You don't mention what you're doing with stdout from the program, are you just letting it scroll on the terminal, or redirecting it to a file? In any case, if stdout blocks (because the disk is slow, for example) your recv buffer will fill up until your program can get the data written. As an experiment, try running the process and redirecting stdout to /dev/null -- if it doesn't exhibit the problem, then you need to look at where you're actually storing the data and speed that part up. Is the data coming in at a fairly constant rate? If not, and you're only having trouble when it bursts, you can work around this by keeping a ring buffer and doing non-blocking writes. It'll make your code more complex, but it will allow your program to absorb some of the bursting data and keep the window from closing -- especially if you've got plenty of RAM. If this is a constant rate of data, however, you're going to need a faster way to store or process or whatever you do with it as it comes in. Getsockopt() says bsd machine's send buffer = 33580, rec buffer = 197100 Is there a way for the bsd machine to find out what the src machine's send buffer size is? I don't know of any way but to ask them. Again, it will only help if it's a bursting problem.

I suspect these are from Linux. Are there equivalent parameters in FreeBSD 6.x ? http://www.netadmintools.com/html/7tcp.man.html Window scaling is enabled by default. I'd assumed that there would be a sysctl to disable it, but I can't seem to find one. It looks as if tcp_wmem is the equivalent of recvspace, although the description in that document is somewhat befuddling. The other end (non-FreeBSD non-open-source) is sending real-time data, and apparently is not able to keep up, its memory fills up, and it starts dropping packets. I suspect the problem is a combination of too much latency (FreeBSD not sending ACKs fast enough) and not enough window size. Can you get some tcpdumps of the traffic? If the problem is what you suspect, it should be evident in a packet dump. net.inet.tcp.recvspace and .sendspace seem relevant, anything else? I'm not a TCP wizard, so please feel free to point out things that should be obvious. :-) Those are maximum values, perhaps your application is not actually allocating that much? Calling getsockopt() on SO_SNDBUF and SO_RCVBUF will tell you, and setsockopt() can be used to change them. I doubt that the BSD network stack has anything to do with this, but perhaps there is something that could be tweaked to help out. I'm hoping that updating the Ethernet device drivers (bge, nve) will result in less latency. Latency isn't the only factor. If your window size is enough, a little extra latency shouldn't hurt. Of course, if the thing is unable to maintain the required throughput, that'll kill you every time. Then there is userland: Anyone want to code review a very simple 80 line TCP-to-stdout utility?

Re: Dual core processors
In response to Jeff Mohler [EMAIL PROTECTED]: Is a stock kernel config the 'fast' way to go on these CPUs? Sure wish there was an 'options I_WANNA_GO_FAST' or an 'options RICKY_BOBBY' that would just do all the right things. Still not sure which scheduler to go with.. Unless something has changed very recently, most of the schedulers are considered experimental and have known bugs. The only one that I know is stable is SCHED_4BSD. Apparently, SCHED_ULE has some nice performance improvements when it's not causing panics. If you're not interested/capable in doing kernel debugging, you probably want to go with SCHED_4BSD. It would appear that some day SCHED_ULE will replace it, but not yet. -- Bill Moran Collaborative Fusion Inc.

Re: OS-BS replacement
In response to Arnold Shade [EMAIL PROTECTED]: In the /tools directory of all FreeBSD distribution there is an old program named OS-BS written by Thomas Wolfram. It is a multi-OS boot loader for MBR (there are two versions: osbs135.exe and osbsbeta.exe) It is rather old, works only under DOS, does not support 1024 cylinders boundary limitation, partitions hiding, etc.. Moreover os-bs has been evolved into commercial SystemSelector so it is no longer maintained by Thomas. However at the time being I continue the development of os-bs under the name mbldr, see: http://mbldr.sourceforge.net/ It is under BSD license, has many cool features, ported under Linux, BSD and Windows, supports extended partitions, etc. I would like to suggest replacing os-bs with the mbldr at some point for FreeBSD distribution if it is acceptable. Could someone recommend me who I should contact (or what mailing list should I use) to discuss this opportunity? I've copied [EMAIL PROTECTED], but I doubt there's any need to discuss this at length. I recommend doing the following: 1) Read the FreeBSD Porters Handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/ 2) Create a port for your program. 3) Submit a PR based on the guidelines in #1, be sure to note in the PR that this port supersedes the old os-bs port, so the committer can do the right thing. -- Bill Moran Collaborative Fusion Inc.

In response to Colin Percival [EMAIL PROTECTED]: Bill Moran wrote: http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-5824 Following the links around, it seems that you would have to mount a corrupt or malicious filesystem in order to exploit this vulnerability. Yes, NIST claims there is no authentication required to exploit? Are new versions of FreeBSD suddenly allowing unauthenticated users to mount filesystems by default? If so, something's wrong with my 6.1 workstation! It seems like this is the 2nd or 3rd vulnerability I've seen that's been blown out of proportion by NIST, or am I missing something? CVE names are assigned, and NIST creates an entry in its database, whenever someone claims that a security problem exists; their purpose is to provide a consistent name for whatever people are talking about, not to decide what exactly constitutes a security issue (as I explained in my BSDCan'06 paper, different vendors have many different policies about what constitute security issues). In this case (and another very similar bug found by the MoKB people), the FreeBSD security team has no intention to handle the bug as a security issue; obviously this is a kernel bug and deserves to be fixed, but no more so than any other kernel bug, and in fact this bug seems far less important than most. That was my thought. In my opinion, anything that requires root access to exploit doesn't constitute a security issue, since someone with root privvies can do whatever they want anyway, by definition. It looks as if MoKB has an axe to grind ... I expect we'll see a lot more exaggerated security problems come out of them before November is over ...

Re: Dual core processors
In response to Robert Fitzpatrick [EMAIL PROTECTED]: I have a server with 6.1 and one dual-core processor and the SMP option was built in the kernel according to the doc below, but only zeros show up in the 'C' column of top after I've rebooted with the newly compiled kernel. http://www.freebsddiary.org/smp.php I did not add APIC_IO as the doc suggested as it complains the option is invalid, plus I did not do this for my other 5.4 server which shows all processors in top. Both configs have a device of apic, neither has the APIC_IO option. However, the other server is running 2 physical CPU's and I see 0 thru 3 in the C column in top. Also, dmesg shows CPU #1 Launched along with everything else: esmtp# dmesg|grep CPU CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (3010.67-MHz 686-class CPU) Logical CPUs per core: 2 FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0: ACPI CPU on acpi0 acpi_throttle0: ACPI CPU Throttling on cpu0 cpu1: ACPI CPU on acpi0 SMP: AP CPU #1 Launched! Why would I not see any other CPU numbers under top like I do in my other server? Based on your dmesg, I don't believe you have a dual-cored CPU. It looks as if it's hyperthreaded, which is different. Hyperthreading is disabled in FreeBSD by default because of possible security issues. It can be enabled by setting a sysctl ...

Re: (SAMBA) issue with filehandles being released under 6.1-RELEASE?
In response to Lowell Gilbert [EMAIL PROTECTED]: Garrett Cooper [EMAIL PROTECTED] writes: Just wondering if anyone else was experiencing the same issues that I am.. it's related to Samba-3.0.22c and sockets / filehandles. For some odd reason every couple days (~2 days) I have to restart the smbd daemon because it eats up 6000+ filehandles, just for sockets I assume (based on netstat output). At the point where it reaches 8000 some filehandles open, the system refuses to fork, forcing me to login as root on the console directly instead of via SSH. My machine is a local / preferred master (smbd fights with XP Home clients because they want to be master browsers), with limited access to a few XP clients (4 clients at any given point in time), plus an XBox using smbclient with XBox Media Center. Have you investigated the possibility that Samba legitimately needs more filehandles than that? Even if there are only 4 clients, they may be opening 2000 files each (The output of smbstatus right before the system exhausted its filehandles would be interesting) If that's the case, you can update the amount of available filehandles using sysctl or by recompiling your kernel.

Questions on first-time installation (Re: (no subject))
In response to Bob Schwartz [EMAIL PROTECTED]: Hi, First, I want to join the lists that you think are best for a highly knowledgable and experienced PC/Windows user who knows little about unix. Would you be so kind as to guide me, please? You're on the right list, but it helps to use a subject line. The install moves flawlessly to fdisk, but I don't understand the screen print and options that the installation files offer when time to select where to install bsd. this workstation has two intallations of XP and a windows boot manager for selecting them. Under no circumstances can we afford for this to be disturbed (at least until we can finally get rid of windows forever!g). You should not install on that machine, then. Its not uncommon for first time users to hose other installations. Based on your under no circumstances statement, you need to ask yourself two questions: 1) Do I have a complete and reliable backup of my Windows stuff? 2) Can I afford the time to restore from backup if I do something wrong? If the answer to either of those questions is no then you should do one of two things: 1) Recruit a trusted friend who has done this before to help. 2) Don't use that machine for your first install. I've put in an adaptec 2940 and a 146 gig SCSI drive...and this is the drive I want to install bsd on and play with it to learn, but the installation process does not appear to tell me how to install on this drive only..and whether or not if I also install BSD's boot manager, I may disturb the one windows is offering already. The BSD boot manager _will_ displace any other boot manager, although it works just as well in every instance I've done it. The box drives are three 73 gig SAS' in a raid configuration. We also don't want to disturb this. I've put in an adaptec 2940 and a 146 gig SCSI drive...and this is the drive I want to install bsd on and play with it to learn, but the installation process does not appear to tell me how to install on this drive only..and whether or not if I also install BSD's boot manager, I may disturb the one windows is offering already. How may I quickly get some help to understand the screen prints about the drives (they do not appear in the install function in any form resembling the numbers or sizes of drives this box actually has) and learn how to install this and get a boot option but without effecting the windows boot manager already there, please? There's a lot of detail missing here. Have you gone through the handbook section on installation? http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install.html If that doesn't help with your questions, you're going to have to provide more information. You say you have 3 - 73G drives and a 146G drive, but you don't describe how they are laid out. What kind of RAID? What do you think you should see, and what do you actually see? -- Bill Moran Collaborative Fusion Inc. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Questions on first-time installation
In response to Bob Schwartz [EMAIL PROTECTED]: [snip] Also, your (or someone else's) suggestion that I disconnect the others for the moment is a good one...and I guess that that would do, except that I would not end up with a boot manager when I hook the others back up afterwards? Also, what, if anything, would that do to any of the data on the other drives after the fact? That's a safe bet, from the standpoint of the Windows installations, but it can cause grief if you try to plug everything back in. I've had problems with the BIOS moving drives around, then FreeBSD can't figure out which drive it should be mounting off. I'm not saying it's a bad idea, all I'm saying is that it might not produce a long-term usable installation. -- Bill Moran Collaborative Fusion Inc.
