Interesting. Is that old perl syntax (v4, etc)? Just curious because
most of the documentation and examples switched to:
sub supfile_set_default_host
{
syntax as opposed to:
sub supfile_set_default_host($$);
sub supfile_set_default_host($$);
{
partly for abbreviation's sake and because I think they moved the
meaning of $$ to the running PID of the script, correct?
I'm rather new to the Perl game though to be honest (been playing around
with Perl for only the past 3 years -- and in particular over the past
2~3 months), so my take on the language could be off.
Thanks for the history lesson in advance :),

tcl84 on FreeBSD 6.2 make error (new user)
G'day all, I'm sorry but I am new to FreeBSD, and I am not sure what tcl84 is, but when I tried to install gdal, using portmanager after many hours it told me that tcl84 had an error, so that was that. when I went to ports/lang/tcl84 and tried make install clean it didn't work either. there were lots of errors like /usr/ports/lang/tcl84/work/tcl8.4.14/unix/libtcl84.so: undefined reference to 'sin' (or 'cos' or 'tan') so I'm guessing that there is some mathematical thing that it needs, but nearly every package I have tried to build from ports seems to require this tcl at some point, so my first few days of FreeBSD are not going as well as I hoped... after much documentation searching and googling etc, I come to this point for help (at least on how to get more help) cheers Ben ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

bind9 in a jail
i was setting up bind9 today in 2 jails. 1 jails is the master, and the other the slave. i am reloading 2 machines that were previously physical machines, into these jails. the master went fine, both internal and external views work as expected. setting up the slave, was not so smooth. i recovered my named.conf from backup, and then removed the external portion of the zones (i dont feel like messing with trouble invovlved with setting up the 2nd ip on the jail). over the past few days while i was setting this up, the master was already in operation, and has had several edits to a few zones. when i reloaded the slave versions from backup into my new slave, and started named, the slaved did not update their zonefiles to match the new serial numbers.i fixed this by stopping named, deleting the zone files, and restarting it again. thankfully, the slave zones all instantly populated, creating matching serial numbers to the ones that are running on the master. do master-to-slave transfers work as expected in a jail, or did i just see some abnormal behavior (possibly due to me not waiting long enough for transfer to happen on its own)? thanks, -- Jonathan Horne http://dfwlpiki.dfwlp.org [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have found that many spammers use my servers name or IP in HELO, so I reject that. Also, reject unresolvable domains etc, simple stuff. Really, if you want to effectively address the problems, store all spam, create a spambox for users to forward their spam to. Analyse it every now and then. For example I did this to idenfity IP ranges sending spam. With greylisting, I have found that greylisting 5 minutes will delay mail significantly and some mail will not be delivered. 3 minutes seems better.

Interesting. Is that old perl syntax (v4, etc)? Just curious because
most of the documentation and examples switched to:
sub supfile_set_default_host
{
syntax as opposed to:
sub supfile_set_default_host($$);
sub supfile_set_default_host($$);

That's actually a function prototype. Prototypes are explained in:

In this case, it's quite easy to run the command in a simple shell

because you want to learn how something like this could be done in
Perl too, that's ok. But it the reason is because Perl is faster,

Hello again all,
I was wondering if there was an automatic, and possibly timed means to
spin down disks available in either ports or the base system, by chance.
Just trying to cut down on energy use, and increase my disks' lives :).
TIA,

Good point. The worst stress points during a disks life are at spin-up
from what I've read.
Also, about the disk spinning at different speeds: many contemporary
disks have acoustics levels where you can adjust the speed on demand
(assuming you knew the hardware level instructions to send to the
controllers). Unfortunately I don't know those settings, so I can't say
what is and isn't possible.
The only upside is at least all disk makers seem to be amalgamating into
either: Fujitsu, Hitachi, Quantum, Seagate, and WD, so figuring out the
standards shouldn't be *too* hard =).

personally, my solution for solving the lower power consumption but still
remotely available issue, by configuring Wake On Lan. my web server is
always on, so i just installed net/wakeonlan there. simple lines in crontab
wake all the rest of my hosts each morning (after im gone to the office of
course) for backups, and then they all power themselves back down about 2
hours later. during the day, if i need to get to a system while im still
remote, i just log into the webserver and wake it backup again.
i would agree that the greatest stress on a disk might just be while its
turning on from cold... but with the warranties that seagate is offering
these days, i feel bold enough to power them off/on at least once a day.

Well, I feel the same but only about WD's drives. Seagate's newer drives
seem to die a lot more frequently than they used to (I've had 4 / 7
Seagate drives die on me in the past few months and 1/6 WD drives die on
me).
But then again that's my take on stuff :).

Hm. Yep, that's what happpened with my 9G SCSI it just
kind of ground or dragged on startup. After 3 tries, it was
kuput.
Also, about the disk spinning at different speeds: many contemporary

standards shouldn't be *too* hard =).
Anyway, I like the idea of saving drives and power if a computer
isn't active. Else if everything can fit into RAM. ...

Michael P. Soulier writes: Might as well paint PLEASE KICK ME! and an arrow pointing down on your back I'm used to binary-package distributions that seem to try a lot harder to not break. I suppose that ports is evolving, and it used to be worse, so I shouldn't complain. Still, if the handbook says to use portupgrade -R to upgrade a port, that's what BSD newbies like me are going to use. Don't mistake me - I use portupgrade, and recommend it to others. But I know from bitter experience it is /not/ bullet-proof.

Sysinstall does not install GENERIC kernel
hit the same bug too with FreeBSD-6.1. To workaround this, i've just added the distribution set GENERIC to dists (this value wasn't mentionned on the sysinstall manpage by the way :-( ) So try with this: dists=base GENERIC catpages info manpages proflibs kernel distSetCustom Thank you. I've also found interesting thread here: http://lists.freebsd.org/pipermail/freebsd-questions/2006-June/123640.ht ml It seems that automatic installation mechanism is far from perfect and there's nobody who interested in fixing the problems. BTW, I've just selected distSetMinimum and in this case kernel was istalled. But except of this a problem I found a new trouble: system commands which I've put in install.cfg doesn't seems to be executed. It just stops with the error 'system -1 command not found' or something like that. Even when the commands are pretty simple like this: command=/sbin/shutdown -p now system It doesn't work and stops with the error. How about your commands? Can you show some examples of your install.cfg here if it works properly? :) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
