Randi Harper wrote: I was thinking that a more acceptable default layout (leaving swap at it's current default size) would be: / = 1GB /var = 2GB /tmp = 2GB One thing to remember is that these are just suggested defaults. Most experienced users are going to use a custom layout when setting up a new server, so the goal here is to have partition sizes that work for everyone else. Although FreeBSD does work on older hardware, I'd guess that most of the hardware it is being installed on now is less than 10 years old. The defaults we currently have in place are outdated. They are targeted more for older systems, perhaps because sysinstall hasn't been touched in quite a while. I'm looking for community input on this, so feel free to pipe up with your $.02. I believe it's been years since I didn't bump up the sizes on an install, otherwise I just end up with all this space where it's least likely to save me from a filled disk in the future. While I am actually running some hardware that is over 10 years old with FreeBSD, quite happily, every single hard drive involved has been replaced due to failure or as a preventative measure. You just can't get general purpose disks that small anymoreI'd think that assuming everyone had at least 10 GB disks at this point would be reasonable. I'm all for increased defaults. -- --Jon Radel j...@radel.com smime.p7s Description: S/MIME Cryptographic Signature

When is it worth enabling hyperthreading?

If I understand correctly, hyperthreading has the advantage >of being able to do CPU context switching faster than the OS, but it No. Both context execute simultaneously. Each logical CPU of the two logical CPUs in a core has its own set of registers, LDT and GDT pointer registers, and instruction counter. Both compete for the same remaining set of resources: DAT, TLB, FPU, cache (all levels for a given core), busses to off-chip resources, and--most critically--pipeline slots per clock cycle. Any time a resource shared by the two logical CPUs (what the logical CPUs execute are called "CPU threads" or "hyperthreads") is in use by one logical CPU, it is unavailable for use by the other logical CPU. If a logical CPU needs a resource unavailable due to its being in use by the other logical CPU, the late-comer's processing is suspended until the resource is released by the other logical CPU. Such a lockout situation is not directly detectable in software because the locked-out instruction is still in execution; it's just taking more than the usual number of cycles to complete. On a P4 Prescott chip or the late models of single-cored Xeons, the pipeline structure is apparently less than ideal for sustained simultaneous execution; i.e., there are frequent pairings of instructions that require more than the available pipeline slots of the types required by the two parallel instructions, which causes one of them to spin until the other moves on, opening the next cycle's set of pipeline slots. A simple case can demonstrate the problem, although on most systems this example would likely be infrequent. There is only one FPU pipeline on these chips, so two floating-point instructions executing simultaneously will result in one getting the FPU pipeline slot for the current cycle, while the other one spins until the next cycle, whereupon the other side will spin, etc. What is actually the more common occurrence is that other types of instruction pairs will require, for example, four slots of a type that only has three pipelines. The Core i7 chips (don't know about the other Core iN series) are alleged to have an improved assortment of pipelines w.r.t. typical instruction mixes, although I think there is still only one FPU per core, so the parallelism is supposed to be rather more effective on these chips than on their forerunners in the Pentium/Xeon series. It has been quite a while since I last tried measuring it, but IIRC, a "make buildworld" on my 3.4 GHz P4 Prescott takes about one to two minutes longer elapsed time in non-hyperthreading mode with MAKEFLAGS set to "-j3" than it does with hyperthreading enabled and MAKEFLAGS set to "-j5" (i.e., something like 52 - 53 minutes instead of 51 minutes and a few seconds). Your quad-core Core i7 chips ought to provide a much greater benefit with hyperthreading enabled, relatively speaking. The traditional recommendation for the -j flag for make(1) is 3*nCPUs, but hyperthreading doesn't give you a full CPU's worth of extra processing, so your quad-core chips won't give you a full 8 CPUs' worth. In other words, a single, large, parallel make job probably should have -j set to something under 24 yet still greater than 12, as a guess perhaps 20ish. :-) But do try it yourself at different -j values, and let us know how your timings turn out on that chip, along with the model number of the chip. >does this context switching systematically instead of only when >requested, so it slows things down unless the number of running >(non-sleeping) threads is greater or equal to let say the number of >physical threads x 1.5-1.75. > In general, there is a slight gain, although running parallel floating-point activities is a break-even situation and not worth the bother unless you're just trying to learn OpenMP or some such. When I've disabled hyperthreading, interactive response has often seemed a tad less snappy when running some CPU-bound process at the same time. OTOH, with hyperthreading enabled, I sometimes notice a bit more jerkiness in things like scrolling in firefox, but it's not easy to tell what's really happening there because firefox typically has at least 7 threads itself. :-) Like Bill Moran said, user interfaces do seem a bit more responsive, and I haven't seen any noticeable *loss* in overall performance.

xorg-server package update on 7.2-STABLE

When I run it through ssh from another computer I can see that it complains: /libexec/ld-elf.so.1: /usr/local/bin/X: Undefined symbol "shmctl" before dying and leaving the main display buggered up. Rebooting the computer is the only way I've found to un-bugger it. Background - Recently installed fresh i386 7.2-RELEASE, and subsequently had X working with the "intel" driver. I ran "portupgrade -aPP" two days ago using packages-7-stable and immediately thereafter experienced the symptoms described above. I see nothing related in /usr/ports/UPDATING since the release date of 7.2. The closest things that turned up Googling variations of the error message has turned up were http://forums.freebsd.org/showthread.php?t=6661 and http://forums.freebsd.org/showthread.php?t=7464 which strike me as "close but no cigar."

Is that feasible, and if so does it come with restrictions that I may have already violated? Any pointers would be appreciated and a solution would be greatly appreciated.

Re: Automatic chmod
User? I only have one user on this shared server. Here's the code:

sys.path.append(os.getcwd())
from login import login
user, passwd, db, host = login()
form = cgi.FieldStorage()
picid = int(form['id'].value)
x = int(form['x'].value)
pics = {1:'pic1',2:'pic2',3:'pic3',4:'pic4',5:'pic5',6:'pic6'}
pic = pics[x]
db = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db)
cursor= db.cursor()
sql = "select " + pic + " from productsX where id='" + str(picid) + "';"

But one has to run '/etc/rc.d/devfs restart' for newly added rules to take effect! (or reboot the system, which is overkill). You can try it out by adding a rule to /etc/devfs.rules and running 'devfs rule show' (as root). The new rule won't show up until after one has run 'etc/rc.d/devfs restart'. Maybe I whould add that to the manual page for devfs.rules? I thought this was obvious, because most if not all rc.d scripts work that way, but mayby it's not clear enough.

A simple basic regex is more than sufficient (in fact this isn't even a regex, it's a fixed string). And the escaping is a problem of the shell, not perl or sed. And by the way, I stongly disagree that perl's escapes are much simpler. In my opinion perl has the most complex escaping and quoting I have seen in any language so far. The basic UNIX philosophy is to use the smallest or simplest tool that does the job. In this case that's clearly sed.

Certainly \x will not help in sed; sed doesn't have it. A simple basic regex is more than sufficient (in fact this isn't even a regex, it's a fixed string). And the escaping is a problem of the shell, not perl or sed. And by the way, I stongly disagree that perl's escapes are much simpler. In my opinion perl has the most complex escaping and quoting I have seen in any language so far. I was thinking of the escapes needed for sed that should not be needed. Some of those are shell problems, many are due to the regex library. More basic things than \x are missing. \t, for instance, or useful \s instead of picking spaces or tabs or trying to navigate using | in sed expressions. The basic UNIX philosophy is to use the smallest or simplest tool that does the job. In this case that's clearly sed. Since sed doesn't have \x, it would appear that sed does not do the job. Maybe I just don't see it. And in most cases, the external simplicity of a tool is more important to the user than its internals. Put another way, if you have it, and it does a better/easier/faster job, why *not* use it? (Not to mention the fact that perl isn't even in FreeBSD's base system, so might not be available at all.) But the OP is using it, so that's clearly not the case here. Or in most FreeBSD installations.

Right, that's an annoying flaw in sed (it doesn't even support the \0 syntax for octal values, which is more standard than \x). Normally I just type such characters literally, which is accepted fine by sed (it is 8 bit clean). However, in this particular case I really recommend to use the "recode" tool (ports/conversion/recode) to convert from UTF-8 to some other encoding. Much easier, and more correct. E2-80-99 (unicode 2019) isn't even a real apostrophe in UTF-8, it's a right single quotation mark. An apostrophe would be ASCII 27. Maybe the OP should configure his software to not save the file with UTF-8 encoding in the first place. I'm not an OOo user, so I can't tell how to do that. But obviously the OP doesn't want the file to be stored as UTF-8. > It's possible "Mastering Regular Expressions" has influenced my thinking > on this. This isn't about regular expressions at all.

I think sed is better suited for this task than perl. That's twice now people have suggested sed instead of perl. Why? For many uses, perl is a better sed than sed. The regex engine is far more powerful and escapes are much simpler. Because sed is stable and perl is getting all OO and flaky. Sed will work like sed for so long as there are unix-like systems.

This is about replacing fixed strings. The OP was using a regex. But my question was "why sed instead of Perl?" tr(1) was also suggested, and is probably better than sed in this case. Of course, tr is another tool that Perl can replace with added functionality.

You would have to look to a firewall solution for this (I recommend PF). There is also software in the ports collection that I've heard of to help this problem. I've never used any of them, but fail2ban seems to be a popular one. I would also recommend using a non-standard SSH port if possible.

Automated login, X and xdm
Dear list, in order to do something that I haven't done for many years, I'd like to have some suggestions or pointers if I do it right. It's a strange, but still typical idea. :-) Here's the problem: A FreeBSD workstation should run X for a specified user after system startup. If the user logs out, he should not drop to CLI mode; instead, an xdm login should be shown to allow him (or someone else) to log in and use X. In the past, I created the auto-login as follows: First, I create an entry in /etc/gettytab, right after the "default:" entry; it contains the al= definition for auto-login as explained in "man 5 gettytab". The name of the user is USER in this example; in fact, is is a valid username on the system: autologin:\ :al=USER:tc=Pc: Then I change the getty argument from "Pc" to "autologin" in /etc/ttys: ttyv0 "/usr/libexec/getty autologin" cons25l1 on secure This automatically logs in the user USER specified as above. In order to start X when he logs in, I put the following lines in his ~/.login: #!/bin/sh mesg y [ ! -f /tmp/.X0-lock ] && startx The user's shell is the C-Shell, so it works. I see the upcoming problem: If a user already started X, then xdm cannot start (as usually done by setting "on" for xdm in /etc/ttys). My idea would be to do something like this into the user's ~/.login file: #!/bin/sh mesg y # very first start of X at (automatic) login # this line will fail if X is already running, but # start it if not [ ! -f /tmp/.X0-lock ] && startx # after leaving X, xdm should be started, but not if # it's already running [ ! -f /tmp/.X0-lock ] && sudo xdm # after xdm is started, dialog mode is back, so the # last entry quits any session after exiting from X logout Normally, there would be the following setting to only run xdm, without autologin, in /etc/ttys: ttyv8 "/usr/local/bin/xdm -nodaemon" xterm on secure But this interferes with the autologin, right? What is the usual way to go? Is there something more elegant? How about "exec startx"?

text2html ?
I had a contractor uppgrade a freebsd machine a while back. Now I am finding things that did not get done corectly. The latest is that I have some other machines that create text files copy them over to this machine, and put them iin the webservers space. Looks like in the past, these files were procesed by /usr/local/bin/text2html, which O would almost certainly have installed from a port. But, I cannot seem to find this port. Can anyone sugest either where I can find this utlity, or what I might use as an alternative? The text files to process are very simple reports of system statistics. Thanks for any ideas. -- One of the main causes of the fall of the roman empire was that, lacking zero, they had no way to indicate successful termination of their C programs. ___ 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 finally got to where I could test this. I'm no Python expert (in fact, this
was the first time I've touched it), but your code, with heavy modifications to
slim it to something that can run on my system, seems to be mostly OK. Here's
the code I ended up with:
**
#!/usr/local/bin/python
import cgitb; cgitb.enable()
import MySQLdb
import cgi
import sys,os
sys.path.append(os.getcwd())
user="root"
passwd=""
db="mysql"
host="localhost"
form = cgi.FieldStorage()
db = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db)
cursor= db.cursor()
sql = "select User from user;"
cursor.execute(sql)
content = cursor.fetchall()
cursor.close()
print '''Content-Type: text/plain
Content-Encoding: base64
'''
print
print content
**
That all seems to work as I would expect and gives not unreasonable output.
Not that I know it's correct or what's needed, but it seems to print what you'd
think it would.
Can you try running a test script that does, Oh, say, something like the below
to see if it works? (AGAIN, I don't know python AND I'm not testing this, just
hand-writing it so excuse my code!)
#!/usr/local/bin/python
print '''Content-Type: text/plain
'''
print "Hopefully this works"
At this point, I really haven't much more to go on. The above may pinpoint
what sort of permissions issue it is. Besides, if it works, you could slowly
add in lines from your previous example until you find the offending line...
Also, If you haven't already done so, you may want to try posting in some
python help forums or something. This doesn't have the feel of a FreeBSD
specific problem, so there's bound to be other Python folks who've hit this and
solved it before.

Re: best FBSD version for commercial use.
My 2 cents, as far as I know 7.1 will be maintained longer than 7.2 according to the freebsd.org website. That is, security fixes will be rolled out for 7.1 a while after 7.2 reaches End Of Life. That made me decide to go with 7.1 when I had to make the switch from 7.0 a few months ago. 8.0 was not out at that time. ___ 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"
