Hmm, if the script is used from cron only, you could reduce it to the
following (note that when run from cron, you may need to use full paths to
your binaries, or set $PATH inside the script):
/usr/bin/rsync -av /var/lib/mysql [EMAIL PROTECTED]:/var/lib/
21 |/usr/bin/tee /tmp/rsync-${TIMESTAMP}.log | /usr/bin/mailx -s My
subject [EMAIL PROTECTED]
This will mail the output and save it to a file at the same time.

Re: [gentoo-user] crontab entry
Quoting Kaushal Shriyan [EMAIL PROTECTED]:
so according to your suggestion where does this line fits cat
/tmp/file|mailx -s my subject [EMAIL PROTECTED] [EMAIL PROTECTED]
in my above bash script
Dirk gave a lovely one-liner, but my guess is you'll get sick of
having to actually check the body of the e-mail to know whether there
is a problem, so you could also put the system call to mailx in the
if-then-else-fi and indicate in the subject line whether it is a
success or failure.
Also, you want to cut out the echo or else cron will send an e-mail
(remember cron sends an e-mail if there's any output from the
command), which is redundant now that you're calling mailx.
Finally, note that you left a '' out of your rsync call. It's fixed below.
#!/bin/bash
#rsync mysql database shell script
#author kaushal
#created on 21/03/2008
TIMESTAMP=`date +%Y-%m-%d-%H:%M:%S:%N`
if rsync -av /var/lib/mysql [EMAIL PROTECTED]:/var/lib/ \
/tmp/rsync-${TIMESTAMP}.log 21
then
cat /tmp/rsync-${TIMESTAMP}.log | \
mailx -s Success: hostxx:yyDB refresh daily [EMAIL PROTECTED]
else
cat /tmp/rsync-${TIMESTAMP}.log | \
mailx -s Error: hostxx:yyDB refresh daily [EMAIL PROTECTED]
fi
Hope this helps,
Cheers,

There's no need for the if-then-else part anymore. You get the whole output
mailed to the given address. However, if you follow Collins very good
proposal, you could do with:
if /usr/bin/rsync -av /var/lib/mysql [EMAIL PROTECTED]:/var/lib/
/tmp/rsync-${TIMESTAMP}.log 21
then
subj_prefix=Success
else
subj_prefix=Error
fi
cat /tmp/rsync-${TIMESTAMP}.log| /usr/bin/mailx -s ${subj_prefix}: host77 DB
refresh daily [EMAIL PROTECTED]
So that you can tell from the subject wether the command was succesful or not.
Bye...

Re: [gentoo-user] AMD vs. Intel on Gentoo?
Hi folks, from an typical SME view (mostly workstation and fileservers) I don't really see an performance difference worth thinking of (as already stated, there're lot's of other bottlenecks, like storage IO). AMD tends to win this battle by price, but Intel tends to be a bit more rubust: I'm still running a bunch of P3 boxes and never get an CPU killed, but Athlon's (plain, not notebook variants) can be easily burned by improper cooling. But with an good cooling (eg. NOT using cheap gel beared fans), I don't see major problems. So for most cases I personally prefer AMD simply by costs.

RISC based). cu -- - Enrico Weigelt== metux IT service - http://www.metux.de/ - Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ - -- gentoo-user@lists.gentoo.org mailing list
[gentoo-user] 1/2 OT: What Linux could learn from mainframes ?
Hi folks, after reading several articles about Mainframes and similar archs (even ancient ones like B7000), I wonder if Linux world could learn something from there. One very interesting point (IMHO) is the storage abstraction. AFAIK, Mainframes work on one large virtual memory (disks for swapping out RAM, tapes for swapping out disks, etc). This way you just allocate some piece of space (like some virtual partition) to an application (of guest). If you need more space, just plug in more disks and the OS will handle all this automatically. I'm currently planning to implement an similar approach for Linux (at least virtual block devices).

Personally I don't think that level of abstraction provides any great benefit for the user, though from a strictly technical standpoint it is at least interesting.

[gentoo-user] iwl4965 performance
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I am using the iwl4965 driver which is included in the kernel 2.6.25-rc6. Everything works fine (Networkmanager, WPA2, etc.) The only thing I experience is a very bad performance. I cannot get more than around 30 kb/s. Also the responses are rather slow. If I open some new tabs in firefox it takes up to 5 seconds before there is enough data to render something. When using wired network its much faster. The router is also not the source of the problem, with my old airo card i could get up to 200 kb/s, the macbook running gentoo gets to around 500kb/s. Any ideas where to start investigation ?

My idea goes like this: * one or more devices are assigned to one block device * a bunch of spare blocks are reserved for defect management (so the device looks smaller than the sum of assigned disks) * if an badblock is detected, it's automatically remapped to an spare block In fact, just what drive-internal defect manangement does, but at OS / driver level. I don't see the point, unless you are dealing with drives that do not have defect management. What makes you think you can accomplish this result better than the firmware on the drive? It seems to me that if the drive firmware missed the opportunity to relocate the bad block, then your window of opportunity to do it in your code has long since passed. IOW, the OS code cannot possibly ever achieve it's design result. Just a thought, maybe you know some aspect of disks that I don't and can see where this would be useful.

[gentoo-user] Linux Motherboard
Hi! I would like to buy a new pc, but since I use linux more than windows (that i use only for gaming), I am interested in hardware compatibility with linux. I'm planing to buy a core 2 Duo platform with a nvidia 8800 GT, but i am very confused about the motherboard. The cheapest shop vendor only have asus motherboard so i don't have much choice. - Asus P5E X38 DDR2 for 189 € - Asus P5K/pro iP35 for 114 € - Asus P5N32-E/SLI 680i for 199€ - Asus P5N-T dlx 780i 232€ Someone have one of those cards or know a good site with information about linux compatibility for those cards? The SLI capability is not important as having ethernet or sound supported on linux. Thank a lot. Nicola -- gentoo-user@lists.gentoo.org mailing list

I've never had a problem with Asus motherboards and Linux - in fact, they are my preferred manufacturer. My last Asus board was an M3A for an AMD Phenom CPU which is irrelevant to your case, unfortunately. However, my last two build have been using Intel Q6600 CPUs (Core 2 quad) using JW motherboards with the Intel P35 chipset so I can say that chipset works absolutely fine with Linux. :) I believe any of those boards you list should be fine but the P5K/Pro iP35 seems to offer the best value for money.

Re: [gentoo-user] Recovering root password
It's probably better to use a shell designed for rescue work, like sash or busybox instead of bash, especially if /usr is on a separate filesystem. The statically linked bash acutally works rather well for this. The main advantage I've found using it for recovery situations is that I'm used to it: sourceing root's .bash_profile is enough to give a familiar environment. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list

And it even would get funnier if the drive's relocation table could be accessed (no idea if this is possible): The LVM would notice if the drive has relocated an (LBA) block, move it out of the way (somewhere else in the LV) and then remove the relocation (never access that LBA block anymore). This way an slowly dying disk can be used for quite a long time. Think of boxes with very limited physical access (eg. outoor field systems) or huge archives w/ non-critical/regeneratable data (eg. media collections w/ originals available, mirrors, etc).
