In 'classic' English (as taught in the 60s and earlier), a comma was
_required_ before a trailing 'and' in a list of 3 or more items, and forbidden
if there were only two items.
The famous "eats roots, shoots..." would parse as eating 3 objects, with the
comma before the 'and'.
for three actions, change the 'and' to 'then', comma before 'then'.
If eating two objects, "eats roots AND shoots *comma* and..." (emphasis added)
The accepted 'rules' changed about the time "new math" was foisted on the
world. The most visible ones involved comma placement, and punctuation
inside trailing quotes.
The password is "frodo."
It is 5 characters long.
The password is "frodo."
It is 6 characters long.
BAH, HUMBUG!!!
Make the first one:
The password is "frodo".
and all the ambiguity goes away.<*snarl*>

how do you write:
The sandwich choices are: tuna salad, chicken, roast beef and
ham, and cheese.
*without* making the last option a '{2 meats} and cheese' sandwich ??
(the next-to-last has two types of meat on it)

the traditional one of these in English is:
Go kill Joe Brown
_who_ is to die depends on whether or not there is a comma after
the second word. Ditto for who -does- the deed.

This is different to "'and' substitutes a comma", but makes sense. For example, I prefer reading the english documentation of FreeBSD (manpages, handbook, FAQ and articles) over their often sloppily and quite "mechanically" done translations. Good quality in documentation helps to raise the quality of the complete product. > This is where the "eats shoots and leaves" comes in, kind of. > There are similar examples where ambiguity arises from the > lack of a comma before "and" in a list.

Proper spelling is easier (at least for me) than artificially avoiding it, like _not_ putting a comma where it belongs to, _not_ capitalizing a word that is to be capitalized, or _not_ using the proper spelling in favour of some "variant". However, I'm not considered "normal" so whatever I do does not imply anything. :-) > > But pleese pay atension too, the new englis orfograffy which > > make`s every thing easyer to under stand and, more freedems > > to mak punctation and les speeling errer's. > > > > Funkzionier't auch in, Deutsch! :-) > > > You must really be taking a conniption fit with the changes > (Verbilligen -- cheapening -- though the exact words I was > searching for have failed me tonight) that have happened in > German in the last 10 or so years ( striking of ß; to always > be written with "ss" now, etc)... The Eszett has been abolished in Switzerland, not in Germany. The "new" rule (historically: old, has been abolished after about 100 years in use because too much prone to errors) says something about "short vs. long vowels" which is nonsense (as vowel length depends on dialect, not on spelling), so some valid ß get turned into ss. Effect: Most valid ß get turned into ss, and even some innocent s get turned into ss, like Massband or Zeugniss. :-) I'm still looking for a valid translation of "bespaßen", an accusative-passive construct of "to entertain somebody". :-) > >> Und "Playboy alles was Maennern Spass macht" ist 100% verständlich > >> auf deutsch, da es einen richtigen Dativ Kasus gibt, im Gegensatz > >> zu englischer Sprache. > > > > It may be 100% understandable, but it's not correct, because it's > > not a sentence or a grammatically valid construct.

A more correct translation would be: >Playboy everything that to men fun makes. Yes, that's much more valid, that's why I wrote "literally", which means sloppy and possibly wrong, because I didn't find a proper way to have the dative case "encoding" without adding additional words, so it's even wronger. :-) > [Or, if you wanted the same mistake (lack of comma or hyphen) but > proper English word order: Playboy everything that is fun for men.] Whom is it fun for? +Dativ.

This is interesting, because the comma before the "and" in a list is much more understandable, because it is open to less interpretation. This is where the "eats shoots and leaves" comes in, kind of. There are similar examples where ambiguity arises from the lack of a comma before "and" in a list. The comma before the "and" is traditional English. There are, however, lots of people who advocate for the lack of a comma before the "and" in a list and that is taught in some classes in some schools.

That matches what I've learned in school, but it doesn't match realitiy anymore. :-) A famous thing is "comma in lists": Unlike German, where "and" substitutes a comma, in English it seems to be valid to put a comma infront of "and": He bought a glass, a towel, a toothpick, and a nose. In German, that would be Er kaufte ein Glas, ein Handtuch, einen Zahnstocker und eine Nase. There are in fact only two exceptions of "comma prior to 'and'" in German. But I don't want to start a school lesson here. The exceptions are closures and appended main clause. :-) > Unfortunately, lots of people forget (or don't pay attention to) > these rules, or, they are casual with them in the casual forms of > communication, like email. Well, I don't think that the e-mail (as a medium) implies abandoning rules for written language. Sure, it's "sloppy" very often, but it should not mangle the languge in a way that the reader has to guess or to ask for what the writer wanted to express. Proper spelling and punctuation help a lot, and it should not be "too much struggle" to get it right: children learn it in the early years in school, so why should adults forget it? > (And there are some people who believe that the "text" language > is English -- OMG, WTF, GR8, B4, LOL, etc -- > http://en.wikipedia.org/wiki/Text_language ) There is also a transition of this written representation to spoken language - some (young) people actually speaking like SMS. I don't think that people actually confuse SMS text with the actual english language. They could have done so almost 100 years ago with Q groups and abbreviations used in amateur radio telegraphy (and even in phone mode), ok dr om, hw? :-) All those "specific language deviations" have their place and are fully valid. It depends on context. For example, if you got a business letter with every 3rd word spelled wrong and containing "SMS and L33T slang", would you take it as a serious information? Form and content have to match. Nobody would accept a tax form printed on toilet paper, even if it would be 100% correct in all content and number details. > Wie mit deutscher Sprache, man kann (mit englischer Sprache) vieles > mit der Wortstellung machen. Und dazu, ist, natürlich, die richtige > Anwendung (und Verständnis) der Grammatik wichtig. Sure it is, but it's not about an 1:1 translation. You need to "think in German" if you want to get it fully right. Baumkuchen... :-) Your sentence would have been: In der deutschen Sprache kann man (wie in der englischen Sprache) vieles mit der Wortstellung machen. Dazu ist natürlich die richtige Anwendung (und das Verstaendnis) der Grammatik wichtig. That is little difference, but it makes a big difference in readability. Note that the structure of a sentence, aided by punctuation, is an important part during the reading experience. Sentences that do not show any structure are hard to read and to understand, and a missing comma can decide about life or death easily: KILL HIM NOT WAIT UNTIL I ARRIVE It's either "kill him, not wait until I arrive" or "kill him not, wait until I arrive", and this translation is not very good as "nicht" ~= "do not" cannot be represented so nicely as in the german equivalent "sentence". Er begann seinen Hut auf dem Kopf zu essen. is another (famous) example of how a missing comma can confuse the reader: "He started eating the hat on his head" is the first interpretation, even if "He started eating, (having) the hat on his head", and the comma already makes this difference. > (Like with the German language, one can do a lot with word order > (in English).

If you have the option of configuring the DHCP subsystem to
hand out IPs according to MAC addresses, that should make you
safe from reboots and _possible_ new IPs. (At least that's
how I've configured my home system so every device will get
the same IP, no matter how or when it requests one from the
DHCP server. It also includes certain port redirections so
a SSH request from external source will _always_ be directed
to the _correct_ machine on the LAN.)

That depends on the pre-configuration of the firewall on the
Linux side. From reading the article I've mentioned, I got the
impression that the firewall would deny SSH connections per
default, and that _you_ would have to enable it if you wanted
to use that service. That is comparable to OpenBSD's "service
disabled by default" policy. I'm still not sure if this idea
will get much love or understanding in Linux land where an
"do everything out of the box" experience seems to be very
important among some distributions. :-)
On FreeBSD, ipfw can DEFAULT_TO_DENY or DEFAULT_TO_ACCEPT, and you
have to specify your rules usually according to the chosen paradigm.
Of course, there are rules to achieve the same effect, even if in
the opposite paradigm.

Then there's the possibility that things have changed. Even though
there should not be a massive or paradigm-wide shift in things, you
never know when using automated updating on Linux. Still the
instructions should be usable at least to identify the steps
involved and the tools to be used.

my netgear and pfSense setup surprised me this afternoon. the
initial setup listed my internal IP as
10.47.0.114,
but something I did changed the DHCP leases section to
10.47.0.113 .
after that, I could ssh out and then ssh back to tao.

I havent used ipfw for many years. the most recent firewall I
ran was on FBSD 5.X and was {i think} "pfw". I got quite good
at it. I should learn more about plain "pf" and pfSense.
do you know if pf/pfsense defaults to DENY incoming connections?
that would explain a Lot!

So! this explains a lot that I've noticed over the years.
remember that im beyong =getting= old; I really Am old.
before I started high school, the rules for commas were
almost set in concrete. my english teacher took points off
if there was an incorrect comma. it looks like in germany
language has remained very strict. {but then, that's why
punctuation exists.}
I've noticed an easing of punctuation--esp'ly in the use of
commas--in how I was taught. but let's face it: it's easier
to text by slacking off. :)

Unlike in English, the comma in German is an important symbol in grammar. It brings structure to sentences. In English, there is the "word order" that achieves this goal, and a comma is mostly optional or "left to preferences". In German, there are rules where to place a comma, and where not to. Those rules are relatively easy to understand, and luckily they do not leave much space for individual preferences. :-) In the above example, Playboy, alles was Maennern Spass macht or better using a hyphen Playboy - alles was Maennern Spass macht would have been correct, as it's shown on the current web page in a correct manner. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ 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"

If the size of the BSD partition is a multiple of, say, !MB, then the _alignment_ of that partition will likewise (auto- magically) be at least 1MB also? No. If you start with $0.63, and only add full dollars or tens, you will still never have an integer amount of dollars. Or do I need to set the alignment separately, e.g. my manually running bsdlabel? (Normally, I've just been using what noadays is being called "guided" partitioning, you know, with the friendly curses-based GUI. So As with fdisk, I have no real experience using bsdlabee from teh command line. But I guess it is time that i learned how.) I don't know of a way to make fdisk and bsdlabel do the correct alignment. But that's okay, because gpart(8) does everything they do, and more. Creating MBRs and bsdlabels is more work, but gpart can do it, and do the juggling to get the bsdlabel partitions to line up. Again, I suggest that GPT is the much easier and more versatile way. But if you insist on MBR/bsdlabel, there are examples of creating it with gpart in the new gmirror section of the GEOM chapter of the Handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/geom-mirror.html ___ 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 assume your "HW firewall" protects you to the outside. Of
course it should allow SSH connections from the outside to
the "tao" box _if_ you want it that way.
But I was thinking about the firewall run by the Fedora OS
that might block SSH connections to "tao", no matter from
where they come, just as if you would have set up FreeBSD's
ipfw with the default to deny connections: without explicitely
enabling SSH connections the server cannot be reached, no
matter if it's running.

Check if the Techotopia article matches your version of Fedora.
It shows how to install and enable the SSH server and also
mentions the "built-in" firewall that has to be configured
to allow connections to that server.

Playboy alles was Maennern Spass macht
Playboy corrected this meanwhile as you can see on www.playboy.de.
Just on the side. Does playboy.com still mirror FreeBSD as they did

A brother-in-law does this for another professional reason. He does or
did those days plastic surgery and has had to see the results of other
people's work. Of course, he was also interested in the articles.
Listening to his comments was more fun than reading the humour page of

No, I think it'll affect the whole thing, because every block will be straddling two 4k sectors instead of filling one. Then the drive has to read and rewrite two sectors for every one block you write, instead of just one, slowing things down to half speed.

Shortly after bringing my FreeBSD system up, I installed GNU GCC 4.8.0 from Ports (/usr/ports/lang/gcc48) and set `CC=gcc48,' `CXX=g++48,' `CPP=cpp48,' et al., in /etc/make.conf. Then, as other ports got built under this configuration, Python 2.7 (/usr/ports/lang/python27) got pulled in for the ride, and when that was built, the above settings made their way into /usr/local/lib/python2.7/config/Makefile: ... CC= gcc48 CXX=g++48 ... CONFIG_ARGS= '--with-threads' '--enable-unicode=ucs4' '--enable-ipv6' '--with-fpectl' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' '--build=i386-portbld-freebsd9.1' 'build_alias=i386-portbld-freebsd9.1' 'CC=gcc48' 'CFLAGS=-O2 -pipe -mfpmath=sse,387 -march=pentium4 -fno-strict-aliasing' 'LDFLAGS= -pthread' 'CPPFLAGS=' 'CPP=cpp48' ... Later, after deinstalling GCC 4.8 and reverting back to using the FreeBSD system compiler, the vestigial settings above would on occasion get invoked when building other ports that presumably used scons or other Python-related build mechanisms, causing the `gcc48: not found' error above. Reinstalling the Python 2.7 port from scratch with the updated /etc/make.conf fixed the problem. Judging from the (lack of) responses, I guess no one else has run into issues arising from using different compilers or compiler versions at different times to build ports :) ___ 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"

The only case where a larger fragment size makes any difference is heavy random i/o on files where the larger fragment size translates to one less level of indirect block in the meta-data. Larger fragment sizes also make for more 'waste' space in the 'used' part of the disk, assuming random file sizes. And reduce the space savings gained by _not_ writing 'holes' to disk.

Custom ISO mount script problem
I have a server that I use to host ISO images, and mount them so they are available via network shares. I ran into a problem today, I temporarily made an ISO image accessible via a md device and mounted it under /mnt just to check the data on the ISO image. My ISO mount script ran its updated check while this was there, and hung up because of it. Now the obvious solution is to fix my script, but as I am baffled as to why it hung-up, it does do a query on md devices, and will try to dismount any that are mounted if they don't match its criteria, and delete the md device as well. However as it would have found this one in use, it should have just returned a failure and continued on. However it didn't and then when I tried to manually umount it, my umount command hung as well. What I was left with was two umount commands attempting to umount /dev/md1000 both stuck, they wouldn't respond to a kill -9 I couldn't use mdconfig -d -u 1000 to delete the md device, even with a -o force (had yet another process stuck). After 1 hour all processes were still hung, killing the shell left them zombied, but still hung there, tying up the md device. I was left with rebooting the server, until I can figure out why my script broke and didn't just error and continue the remaining checks in its list. Does anyone have any idea how if this happens again to kill these hung-up umount processes, without rebooting the server? This could be a fun one to fix, because so far attempting to duplicate the problem hasn't worked, think I just have to time something just right, or wrong depended how you look at it. -- Thanks, Dean E.

Whereas this -f parameter for newfs is, I gather, the thing that really tells the kernel the size of the physical chunks of data that it can/should read/write to the drive at any one time, right? And while we are on the subject... Has anybody ever down any analysis (i.e. benchmarking) to find out if -f 4096 is even the best number for a modern high(er) capacity drive? I'm just sort-of wondering if 8192 or 16384 might be better. ___ 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"

well, it works. im not sure what I did, but no comp;laints!
I'm running pfSense in a netgear box. before I rebooted, my
local IP ended in .114; after and now it moved to .113. when
I did an ssh 10.47.0.113, voila! the new tao requested my password.
and I was in. and go ssh back and forth. Whew!
thanks for the help, guys.

what the Playboy did to the German language ...
Playboy's German tag line missed out on a comma too. It was obviously a
mistake. I have heard that they brought it back after decades of no
comma in the tag line.
You know, while in other countries man could say that they read Playboy
only because of the articles, in Germany they read Playboy only to check
on the comma.

hmmm. that might be it. my firewall is in a nice small, 4w netgear

problem with pkgng
I am attempting to migrate a test box to pkgng, and have run into difficulty: When I run the pkg2ng script, it fails to register postgreql-jdbc because one if its files, namely /usr/local/share/doc/postgresql/README-client, is also installed by postgresql-client-9.2.1. In this, pkgng is perfectly correct, but how do I work around the issue? My assumption is that I will need to use pkg register with a hacked plist file from which the offending entry has been removed. Can anyone shed light on how to achieve this?

Some thoughts about upgrading from 8.3 to 9.1
I just read in another post about disklayout _ According to the manual as of 9.0-RELEASE the default fragment and block sizes for newfs are 4k and 32k, so provided your partitions/slices are 4k aligned everything Should Just Work. Before 9.0 fragments and blocks were 2k and 16k which doesn't play so well with 4k drives. I started thinking about the choices I have for upgrading my running 8.3 systems. I'm aware about of the procedure with freebsd-upgrade and rebuilding all ports according to man portmaster. Would you just do the upgrade or would you consider reinstalling?

Re: Old file reappeared by itself
12.11.2012 14:07, Artem Kuchin: The machines runs 4 jails. Everything is in the jails except NAMED. Named is run on the root host (if i may say so) itself. There is a zone file there which i changed last week. Today in the morning i try to open a site and host name is not found. It worked on friday. I went to see the the zone file. IT WAS DATED 2010 I open it and the serial number is something like 201103021. I do all my serials using dates, so, while the file date is 2010 the content is from 2011 and it sure does looks so. Then i go to secondary zone (slave) on another server and there i find the zone from last week. I checked all logs and did not find anything special. The zone file from 2010 just reappeared from nowhere kill all the new changes. As i said, i saw things like this in the past. It happened insides jails and was related to files for web sites and i thought that i and someone else messed up. No i think i saw the same thing. It happened today again! I checked file today and the file was dated 5 oct 2012 but content was from a week ago except the serial. I changed it yesterday. No automatic backup or restore is running.

That's a shame, nginx is definitely a robust and fast server, it's well maintained, it's patched quickly... If you need proof of its prowess to convince your upstream managers, I'd be inclined to provide you with a diagram of our architecture for this particular project, as well as the graphs (network traffic, server loads, requests/sec...)

Re: high performance server design approach
Define "high performance" , what are your expectations in terms of concurrent connections, requests/second and all ? Allow me to shed some measure of light here, we're running 16x web servers with nginx doing *permanent* (as in, for all requests) URL rewriting and serving 500 req/s each. These servers admittedly running debian are behind 4x freebsd boxes using a combination of PF, CARP and relayd on 8.3-STABLE. The web servers deliver 200mb/second worth of *small* files (roughly 1kb javascripts). They hardly ever reach 0.25 load average, on 8 cores + hyperthreading. What I'm getting at here is, nginx *totally rapes* performance-wise, at least for our own needs. If it is able to deliver 500 req/s (for each server) of small files, surely it can handle the load you're planning on throwing at it ?

Issues with smartd starting up at boot time - delays sever start?
Hi, I've noticed on our systems (9.0-Stable, amd64) that starting smartd at boot time massively extends the startup time of the box. I think I've traced this down to smartd, and our use of the '-M test' config option (which sends a test message, apparently forking to 'mail' - and, as the config man page says - it will block until that command returns). For whatever reason (networking not stable at that point in time, MTA not started yet etc.) - on our machines this leaves smartd handing around for minutes - before it returns, the machine starts up (and the status emails arrive). Can anyone think of a 'simple' fix for this? - Is there anything I can do to '/usr/local/etc/rc.d/smartd' to make it run later in the startup process? Does the dreaded '/etc/rc.local' still get run -after- everything else? (Worst case I could launch it from there).

Leave at least one core for the OS, so, have X >= 2. I would not fork at all. Have the threads ready when the requests are coming. At least this is what I did several years ago achieving the highest performance. Make X a variable to be able to tune a bit.

The FreeBSD ones, the MBR ones, or both? The partitions, all of them. :-) For MBR partitions, the "DOS primary partitions", which are slices, you typically only need one if you want to stay in compatibility mode. For dedicated mode, you don't need it. The slice typically starts in sector 63 and occupies the space until the end of the device. The partitions within the slice should have sizes of multiples of 1 MB or 1 GB (which makes them multiples of 4k easily). See: http://www.freebsd.org/doc/handbook/bsdinstall-partitioning.html Even though the handbook elaborates on the GPT approach, it will work with traditional disklabel partitioning too. Note that 4k = 8 x 512 byte, and so 64 sectors would be a good alignment "grid", while 63 sectors is not. That implies that in case you use fdisk to create a slice holding your partitions, try to make it start at sector 64 (63 would have been the default). After that, use bsdlabel to create the partitions inside the slice as you want. Make them multiples of 1M or 1G, that should be no big deal because disks are big and cheap today. :-) You can then easily use newfs with the -f parameter: newfs -U -f 4096 This will make sure the proper fragment size will be applied upon formatting the created partitions. Also see: http://www.wonkity.com/~wblock/docs/html/disksetup.html As I have limited experience, anyone having more practical experience with this matter is welcome to comment. :-) According to the manual as of 9.0-RELEASE the default fragment and block sizes for newfs are 4k and 32k, so provided your partitions/slices are 4k aligned everything Should Just Work. Before 9.0 fragments and blocks were 2k and 16k which doesn't play so well with 4k drives. ___ 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"

The dhclient is a client (just as the ssh program), while
the system has to run some kind of SSH _server_ (sshd on
FreeBSD for example). Additionally, network configuration
and especially firewall has to _permit_ the access to that
specific service (that has to be enabled).

There is a nice summary on how to get the OpenSSH server
set up on Fedora:
http://www.techotopia.com/index.php/Configuring_Fedora_Linux_Remote_Access_using_SSH
Basically, it's about installing and enabling it. The article
also discusses how to enable configure the firewall properly.

5 mins later: I ssh'd from tao to ethic then used the ssh-vvv

is from OBSD:
SSH2_MSG_IGNORE
so if anybody running openbsd or fedora, or anybody who has stubbed
