What's overpartitioning? ;-)
That's when you say, 500M is plenty large for /var, except for this mail
archive directory, which could grow really big under some failure
conditions, so you create a 100G /var/archive partition and 500M /var
partition, then discover that under the OPPOSITE failure conditions,
massive amounts of mail ends up in /var/spool. At that point, you realize
that splitting off the two partitions sounded good, but instead it just
cost you some embarrassing down time and didn't help you in the slightest,
AND PROBABLY NEVER WILL (and in fact, I can now think of other failure
modes where it could bite me). Should have just put it in one huge /var
partition.

Yes, agree, except for when slices have different mount options, such as
exec for /var/www - cgi-bin, and for dumping.
I thought it was best pratice to umount a slice before dumping, but a
quick flick thourgh the man page states:
files-to-dump is either a mountpoint of a filesystem or a list of files
and directories on a single filesystem to be backed up as a subset of
the filesystem. In the former case, either the path to a mounted
filesystem or the device of an unmounted filesystem can be used. In the
latter case, certain restrictions are placed on the backup: -u is
ignored, the only dump level that is supported is -0, and all of the
files must reside on the same filesystem.
I have been umounting to dump with this in a script:
dump -${level}anu -f - -h 0 ${device} | gzip -9 -o ${file}
$ sort /etc/dumpdates

I think, that the SATA controller is a ICH7R (82801GB /82801GR), but I dont now exatly, and i cant find any information in intel.com After i reset the machine, there is no problem to boot again(afther checking hard drive).

What connects to what, and which IP address are we talking about (does the phone get an address from the firewall? The firewall from the ISP?)? From which traffic should the IP be extracted?

I interpret the above snippet to mean `dump works best on filesystems,
not files'. As to unmounting before dumping, that's possible but, IME,
not usually necessary.
Of course, you *do* have to know what you are doing. Dumping a running
/usr is pretty much okay - it's not going to change, after all. On the
other hand, dump and PostgreSQL aren't friends (which is why pg_dump is
useful, this creates a backup in a file).
My backups run at night, when very little things are using the machines;
but I do not unmount (or mount read-only) any filesystems before dumping
them.
However, if you can get away with unmounting stuff, it might be
preferable. I just never bothered.

Because after the first *ptr++; you actually have ptr == ptr.

++(*ptr);
printf(x=%d, *ptr=%d, ptr=%p, x=%p\n, x, *ptr, ptr, x);
return 0;
}
--
The output I get is this:
$ ./a.out
x=2, *ptr=2, ptr=0xbfbfece0, x=0xbfbfece0
x=2, *ptr=-1077941020, ptr=0xbfbfece4, x=0xbfbfece0
x=2, *ptr=750764012, ptr=0xbfbfece5, x=0xbfbfece0
---
If ++(*ptr) is supposed to increment the value *ptr, then why is there a
change in memory address (0xbfbfece5) ?
Because *ptr++ is equivalent to *(ptr++)? Try:
#include stdio.h
int main(void) {
int *i, x[9] = {0, 1, 2, 3, 4, 5, 6, 7, 8};
for (i = x; i x + 9; )
printf(%d\n, *i++);
return 0;
}
And note that the equivalent with (*i)++ does something very different.

Screen resolution and ACPI
Hi, I am using OpenBSD 4.0 with KDE 3.5.4 I am looking for how to change the screen resolution which is stuck to 640*480 at the moment. KDE option to change the screen resolution is greyed out. I have been pointed out to change the XF86Config file but this file does not exist on my installation. Also I would like the PC to actualy shut down when I do shutdown -h now instead of having to press the power button. This option is supported but disabled by default as far I have read, but how to enable it ? Thanks a million in advance -- View this message in context: http://www.nabble.com/Screen-resolution-and-ACPI-tf2875353.html#a8036593 Sent from the openbsd user - misc mailing list archive at Nabble.com.

I don't know about the multiple routing tables, but it can, at the very worst case, be done with 2 hosts, both of which do NAT. However, I'm fairly certain that careful abuse of pf's route-to will allow you to make this work. Although I'd caution against trying to make it work from the firewall itself, too. Joachim
Re: Screen resolution and ACPI
Ok found it. I have used the XORGCFG tool to proceed and I have been able to change the screen resolution. Also for ACPI I would need to recompile the kernell as it was (Still is ?) more or less experimental.

Re: Extract IP to table
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Joachim Schipper wrote: Hi Joachim I don't really get what you want to do. What connects to what, and which IP address are we talking about (does the phone get an address from the firewall? The firewall from the ISP?)? From which traffic should the IP be extracted? Are you aware that this is almost certainly not very secure? The VOIP phone is connnected to a D-Link router which is connected to an ISP via DHCP. This is connected through the Internet to the head office firewall which uses a static IP specifically for the VOIP phone. The VOIP phone is hardwired to call home to the allocated firewall IP at head office and it uses specific ports to boot and stay alive so they are easily detected when the phone calls home. The address of the DHCP Dlink router will change at some point so I want to be able to detect the IP change at the firewall and automatically insert the new DLink router IP address into a table on the firewall so connnectivity is uninterrupted or a least minimized. What I am hoping to be able to do seamlessly is extract the IP from the phone traffic when it calls home, basing it on port number and insert the IP into a table. I would like to run something like authpf using the $userip macro but the workstation at the VOIP phone office is an HP terminal. I had setup an OpenVPN box which worked very well but it was unplugged for unknown reasons as it is not my network. A little extra info: Once the traffic gets through the firewall it is then connected to a control unit that reads the embedded MAC of the VOIP phone and if it matches it then moves on to setup a full connection. The VOIP phone MAC supplied by the phone during the phone boot phase. If the MAC doesn't match, no connection.

Asus RS-120-e3 (PA2) Compatibility with OpenBSD 4.0?
I would LIKE to install OpenBSD 4.0 on the new Asus 1u rackmount server we just acquired. This server is going to be replacing our core portal-web server, running Python/Zope/Plone with MySQL, and rsync to mirror sites around the globe. I just joined this list this week, after searching through the FAQs, and general web-searching. I'd like to know if there are going to be any serious compatibility issues. I've tried to find a comprehensive list mapping OpenBSD 4.0 to the list of hardware on this system, but unfortunately I either I'm missing something, or else there's a lot on this system that is NOT especially compatible. I've installed the default bsd.mp just fine, and I'm trying to figure out how to use that with the correct Raid drivers. I have been using this as a guide for general RAID support, not knowing for certain if this is what I need: http://www.eclectica.ca/howto/openbsd-software-raid-howto.php I compiled it with a generic single cpu kernel, but I haven't yet figured out (just started on it yesterday) how to merge what I need for RAID support and MP support. We are a total volunteer run community, so please be patient with me/us. I've used Openbsd on and off over the years, but only for basics like firewalling and such, and the last time I actually did any work with OpenBSD was at least 2-3 years ago unfortunately. I've usually used different Linux distros for web-servers, file-servers, etc. mostly because OpenBSD didn't support multiple processors back then. Now that it does, I'm very glad, since I've liked the default security approach, stability, philosophy, etc. of OpenBSD, but it'll take a little getting back into it. If this is the wrong list to post this to, please direct me as to the correct one. Below are the questions I have: How is the support for RAID1 on this LSI chipset? Since there are Linux drivers, is there any problem with the LSI raid? How is the thermal/monitoring support in OpenBSD on such a system? Does the mp kernel support 64 bit or only 32 bit processing? Any known issues with the dual core cpus? How much support is there for dvd burning with dual layer? Here are the specs for the system. Please either point me to the appropriate links/pages for working with the hardware and/or let me know any gotchas for that hardware.

Re: Weird values in sensors values from it(4)
Don't worry, your machine is OK. I've got this behavior on a few of my machines. I'd expect it's a result of the overall crappiness of the x86 platform rather than a bug in the driver. Seeing how it(4) was added in 3.4, said crappiness probably involves cheap design and hardware as well as a HUGE diversity in how various vendors implement these sensors. Figuring out that they are even there on the i2c bus let alone WHO they are has got to be some tricky work. Looks like there's some new stuff in -current related to sensors, a two-level api. I don't know what this does for sensors, but it has to be good! =) Travers Buda On Sat, 23 Dec 2006 21:18:54 -0600 Matthew R.

As to unmounting before dumping, that's possible but, IME, not usually necessary. Thanks, I'll keep that in mind for when it is not practical, whatever that means at the time. Of course, you *do* have to know what you are doing. Dumping a running /usr is pretty much okay - it's not going to change, after all. On the other hand, dump and PostgreSQL aren't friends (which is why pg_dump is useful, this creates a backup in a file). My backups run at night, when very little things are using the machines; but I do not unmount (or mount read-only) any filesystems before dumping them. However, if you can get away with unmounting stuff, it might be preferable. I just never bothered. I've been shutting down postfix @ 4am, umounting /var/mail, dumping. Similar for /home with courier-imap, /var/www, I copy /etc, /root, crontabs, /usr/local/site, /var/spool/mailman, to /var/dumpster dump that, then ftp the lot off site so there's no human input needed for tapes, CDs, wotnot.
