How should I deal with package conflicts such as
apache13/apache13-mod_ssl...
I've installed apache13-mod_ssl but a couple of other ports I want
to
install want apache13 (specifically apache-1.3.29_1) which
complains of a
package conflict (with apache+mod_ssl-1.3.29+2.8.16) so I'll
have to force
the installation. Is there a way of convincing the new packages that
apache13-mod_ssl is an adequate substitute for apache13?
Set the APACHE_PORT variable (to www/apachewhatever) in
/etc/make.conf. This will only work with ports, not packages, for
which one can only use the default settings.
Ok, does it matter that the port I want to install doesn't have any
references to APACHE_PORT in its Makefile? Grepping through /usr/ports I
can see that many ports do, but the port I want to install
(mail/squirrelmail) doesn't.
If squirrelmail has a direct dependecy like BUILD_DEPEND=...www/apache13
then it does matter. If squirrelmail depends on other ports that have this
kind of dependency then it does matter too, if these other ports have their
dependency set via APACHE_PORT then it does not matter.
Here we had a similar problem with apache13 packages: We have different
setups for workstations/servers, some have mod_ssl apache some have
apache13 only. All setup is done via packages, not ports. We have a compile
workstation that creates the packages to install. Our solution: Ports may
have subversions, which allows dependend packages to refer to the port and
accept all subversions as a valid dependency (with a warning). Example: You
can install the popular postgresql database either as server or as client
only. All deps to postgres client will be fullfilled by both packages.
To build mod-ssl apache13 package as a variant of the apache13 I renamed
www/apache13-modssl to www/apache13 (necessary for pkg-database) and
modified the Makefile like this:
diff Makefile.orig Makefile
8,9c8,9
PORTNAME= apache+mod_ssl
PORTVERSION= ${VERSION_APACHE}+${VERSION_MODSSL}
---
PORTNAME= apache
PORTVERSION= ${VERSION_APACHE}
16a17
PKGNAMESUFFIX=-modssl
The last line make the variant of apache13: apache13-modssl.
Well, this is of course a hack, because modifications of the ports usually
are not such a good idea: If you cvsup all modifications will be lost. Our
focus was to have precompiled packages for automated setup. We modified the
ports Makefiles because we believe that we know what we are doing (and
others will know better and roll the eyes :-). Most probably there is a
better solution for this scenario but I didn't found one and I wanted to
learn more about the ports system so I did it this way.

I agree with the recommendation to learn LaTeX. It's probably the best
way to generate PDF output and it's widely used for document generation.
I disagree that one needs to use pdflatex, though. Those side-effects
you mention are trivial to get rid of:
1. \usepackage{times} (or palatino or bookman or whatever font
package you like)
Does this work without _any_ problems when you want to use the
(tex-default) computer modern fonts? My experiences over the last years
with different platforms and latex installations are, that you alway have
to google-around to get this working. I use LaTeX/pdf output only from
time to time so I am not the big expert, but using pdflatex a while ago was
the first time I got the CMR fonts into a pdf without any display/print
problems. I just made some slight modifications to my latex file necessary
for pdflatex (mentioned in the pdflatex doc) and whoops, there it was.

I do not feel like rebooting again right now just to see if using autoselect works, I'd rather not have to call them today to fix it once more ;-) Sounds like that at the other end of the patchcable autoselect still is active and is unable to agree with the fixed media realtek card. So I would suggest to check the router/switch at the other end of the patchcable and to also switch off autoselect there. tcpblast from the ports is a handy tool to check tcp troughput. To be on the safe side you should tcpblast in both directions. Expect about 10 Mbytes/s with no other network load. Btw.: I have no experience with Realtek hardware, so there may be other things here causing the error. with best regards Alexander -- Alexander Haderer Charite Berlin - Germany To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

I'd expect a system of the kind that Maarten's talking about to be able to transfer at least 40 MB/s sequential at the disk. That would mean he could backup over 1 TB in an 8 hour period. Of course you are right. My note a. was meant as a more general hint to think about transfer rates when dealing with large files/filesystem. Maarten gave no details about how the webservers are connected with the backup server. I should have give more details of what I mean: When backing up 50 Webservers over network to one backup server the network may become a bottleneck. If you have to use encrypted connections (ssh) because the webservers are located elsewhere you need CPU power at server side for each connection. b. Using ssh + dump/cpio/tar needs CPU power for encryption, especially when multiple clients safe their data at the same time. You can share the compression across multiple machines. That's what was happening in the example above. It is a good idea to do compression at the client side. As I understand your example /dump/wantadilla/2 is either a local dir or connected via NFS. The latter requires a local network if you don't want to do NFS mounts across the Internet.

Re: Possible drive failing??

Does this signal possible disk troubles or potential failure? Here's the message. ad0s1g: hard error writing fsbn 13434039 of 5930556-5930559 (ad0s1 bn 13434039; cn 836 tn 58 sn 45) trying PIO mode ad0: DMA problem fallback to PIO mode Is that something I can ignore, or should I keep an eye on this?? Well, there is some possibility that it's just a one-time hiccup. More likely, the drive has already exhuasted it's supply of replacement blocks, as modener drives do bad block remapping all by themselves. In the latter case, the drive is about to fail catastrophically. At the very least, I'd keep a very close eye on the drive, and double-check my backups if I saw that happen to one of my drives. Depending on how critical that system is, I may have a backup ready, or replace the drive under controlled conditions before things get worse. I completly agree with Mike. We have lots of IDE disks running under FreeBSD and made some experience. Here are some additional Tips: 1. The disk may still run for some days and then fail completly with a kernel hang, as Mike wrote above. 2. Switching the system off and on may force the final shutdown of the disk. 3. try doing a backup with PIO mode on as long as the disk is willing to talk to you 4. download the diagnosis tool from the disk manufacturer and do a deep test. According to your message I expect the diagnosis will detect errors. Check the drive guarantee. 5. Cable and connector problems usually show up as UDMA CRC error with falling back to PIO. In this case try to downclock the UDMA mode with atacontrol mode (FreeBSD 4.6 ? and above). with best regards Alexander -- Alexander Haderer Charite Berlin - Germany To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
Re: Vinum raid0 disk dies
At 18:27 07.03.2003 +0100, Thomas von Hassel wrote: So if one of your disks in a vinum raid´0 dies there is absolutly nothing you can do right ? ...just checking before i zero the other drives .. It depends how dead your disk is: If its completly gone away (disappeared in kernel boot message) your only chance I see is to start searching for the backup. If the disk only has some dead sectors, you can try to clone the data with dd to a new disk. This is slow and cumbersome, and as a result you have some blocks of invalid data on the new disk. The trick with dd is to skip the dead sectors and to use a blocksize of 512. See man dd for the options seek and skip. dd copy blocks until it detects a bad block. Here you have to start over with new seek/skip to jump over the dead sector. So the job would be something like this: - umount vinum fs - stop vinum - add new disk to system - clone old disk with dd to new disk - remove old disk and install new disk instead - new disk: zero first 265 sectors of the slice - disklabel new disk as was the old disk (Handbook: Adding disks) - vinum create -f diskfile (see http://www.vinumvm.org replacing disks) - start vinum - vinum setstate of disks/plex/vol to up - vinum saveconfig - fsck vinum fs - mount vinum fs Changes are good to destroy all data with this steps shown above. Read manpages dd, vinum, disklabel, fdisk. Understand what you do. Think before hitting return. Expect the worst when using the wrong parameters. Use backups. with best regards Alexander -- Alexander Haderer Charite Berlin - Germany To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
vinum: low level access to subdisks / drives
Hello, Here is a vinum question. Assume this setup: Two partitions ad0s1e and ad2s1e of type vinum with the same size. vinum is set up to use this disks as RAID 1 (mirror): drive drive0 device /dev/ad0s1e drive drive2 device /dev/ad2s1e volume mirr plex org concat sd len 0s drive disk0 plex org concat sd len 0s drive disk2 newfs has been done and the /dev/vinum/mirr is mounted to /mirr with rw access. Everything is working without problem. Because we do not rely on the harddisks and the files at /mirr are accessed seldom and random, we want to check, if all sectors of the disks ad0 and ad2 are readable without problem. To do so, we want to run a nightly low priority cron job that tries to read all sectors of a disk without further analyzing the data read. The result of a failed read (hard disk failure) will be a kernel message in /var/log/messages, which we monitor 24x7 a day. Lets say we do dd for reading the sectors: dd if=/dev/ad0s1 of=/dev/zero bs=1024k Questions: 1. Will this conflict with vinum or its internal (kernel) data structures when vinum is running the same time with all components of the RAID 'up'? 2. Will this conflict with parallel read/write access to /mirr ? 3. Should we use dd if=/dev/vinum/sd/mirr.p0.s0 ... instead of /dev/ad0s1e ? with best regards Alexander -- Alexander Haderer Charite Berlin - Germany To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
