[CentOS] OT: Photo Editor to reduce 272 photos to VGA at once
I returned from Bogotá and have a Folder with 272 photos that total 419.9 MB. I would like to email them to several people who were there for the concerts I attended. I have Picasa, gThumb (not really an Editor but I believe it can reduce the quality of photos) and The GIMP installed. Is there a way I can have a photo editor reduce all of them to VGA size, without doing that 272 times? The people who will receive them are using M$ Windoze. Also, they are in a folder and it doesn't seem possible to attach a folder in gmail. A good way to zip them up in one file that can be unzipped on Windoze boxes? TIA! P.S.

Jason Pyeron wrote: > "Inexpensive - Amazon EC2 passes on to you the financial benefits of > Amazon's > scale. You pay a very low rate for the compute capacity you actually > consume." Which is kinda funny since it's not true in many situations. My company did a cost analysis of using the Amazon cloud vs doing it ourselves, and the cloud cost at Amazon was more than double what we would pay if we did it ourselves(TCO over a 3 year period). And that's just the cost of the services themselves. We do need hundreds of megabits of internet bandwidth, and lots of CPU cycles as well as I/O cycles(and disk space), in the micro pay model that Amazon has it adds up fast.. I'm sure it's more cost effective if the stuff your doing sits idle most of the time. We also priced out a premium enterprise provider that used VMware enterprise and they came in at about 4x the cost of doing it ourselves, CPU cycles in VMware enterprise are of course a lot more expensive than non-vmware or even VMware foundation. The premium enterprise VMWare vendor(Terremark) came within about $15k of the cost of using Rackspace managed hosting(bare metal) to do the same over a 3 year period which I thought was very interesting, shows how expensive managed hosting can be as well(we weren't looking for much software on hands support but rather hardware support, leasing the equipment through them etc). So not surprisingly we're doing it ourselves, which makes me happy as an infrastructure guy. Building new sites and setting up new things is something that keeps me happy. I interviewed some guy for an operations position last week who was proud of the fact they had migrated to the cloud, and it was working great. Then I asked him what kind of traffic do they get and how many servers? They got something like 10,000 requests a DAY, and they had 2 or 3 servers.

I have not bothered with this because I'm not using kde anymore, but the kdegraphics update with Centos-5.3 caused this by installing the program and re-configuring (explanation next). I've tracked down the problem, though, so I can stop kghostview from being invoked. When RPMS install, they often have a post script call to execute "update-desktop-database" which scans the desktop files under /usr/share/applications and it builds /usr/share/applications/mimeinfo.cache. To my surprise/astonishment, the update-desktop-database function is completely undocumented, not even a man page or a mention in the README file from the xdg group that provides it. To my even greater surprise, there is apparently no way to predict which programs will be at the front of the list for each mime type. The mimeinfo.cache is used by programs like nautilus to know what programs are available. update-desktop-database, for reasons I don't know, places ghostview first among pdf opener programs. More and more programs are relying on the "xdg-open" script to select viewers for files. xdg-open ends up scanning for the desktop framework in use, in my case Gnome, and then it passes off the pdf file to the program gnome-open, which is supposed to check for "defaults.list" in the user's config and in the system at /usr/share/applications. The mimeinfo.cache file is not supposed to be dominant setting here because the preferred viewer is supposed to be specified in defaults.list. We have AdobeReader.desktop specified there. However, when the config in defaults.list is broken, then xdg-open (hence gnome-open) don't know what to do, and they consult mimeinfo.cache and they take the first program listed. Our config was broken because Adobe was installed incorrectly. The RPM that installed AdobeReader did not copy AdobeReader.desktop into /usr/share/applications. As a result, when the user tries to configure "xdg-open" (via xdg-mime) or use "gnome-open", both try to use AdobeReader.desktop, and fail, and then they fall back to use the things in /usr/share/applications/mimeinfo.cache. One can just copy AdobeReader.desktop from /opt/Adobe/... into /usr/share/applications to fix this. To be fancier, one can run " To protect my systems from ever using kghostview, I ended up deleting the Mime line in all of the relevant desktop files in /usr/share/applicaitons/kde. After that, "update-desktop-database" can be called and kghostview is never listed as a pdf opener. -- Paul E.

Re: [CentOS] Adding an 'official' CentOS image to the Amazon EC2(Electronic Compute Cloud)
I don't have much experience with AWS yet, so I can't speak to any support issues. We're looking at leveraging it for automated builds initially (occasional up time) for proprietary and open source projects. For making an image public, it would obviously be great if Amazon would sponsor the image... However, if this isn't the case maybe centos.org could publish an image identifier(s) on their website and then have it labeled 'public' on the AWS console. Each image has a unique identifier used to instantiate it, so as long as centos.org publishes approved ids then that would be a pretty good work around in my opinion.

[CentOS] stale dm-multipath mappings
Greetings, I've hit this exact 'bug': https://bugzilla.redhat.com/show_bug.cgi?id=491311 I need to remove the mappings manually. I assume this is done via 'multipath -F' followed by a 'multipath -v2' ? Has anyone experienced doing this on a production system? We can do it during hours of low activity, but we would prefer to keep the databases on this host online at the time. The LUNs themselves are completely removed from the host and are not visible on the HBA bus.

Just wondering what sort of impact this has to your system? If the
paths are gone they won't be used, so what does it matter?
I have a couple batch processes that run nightly:
- One of them takes a consistent snapshot of a standby mysql database
and exports the read-write snapshot to a QA host nightly
- The other takes another consistent snapshot of a standby mysql
database and exports the read-write snapshot to a backup server
In both cases the process involves removing the previous snapshots
from the QA and backup servers respectively, before re-creating new
snapshots and presenting them back to the original servers on the
same LUN IDs. Part of the process I do delete *all* device mappings
for the snapshotted luns on the destination servers with these
commands:
for i in `/sbin/dmsetup ls | grep p1 | awk '{print $1}'`; do
dmsetup remove $i;
done
for i in `/sbin/dmsetup ls | awk '{print $1}'`; do
dmsetup remove $i;
done
I just restart the multipathing service after I present new LUNs
to the system. Both systems do this daily and have been for about
two months now and it works great.
In these two cases currently I am using VMWare raw device mapping
on the remote systems so while I'm using multipath, there is only
1 path(visible to the VM, the MPIO is handled by the host). Prior
to that I used software iSCSI on CentOS 5.2 (no 5.3 yet), and I
did the same thing, I did the same thing because I found restarting
software iSCSI on CentOS 5.2 to be unreliable(more than one kernel
panic during testing). The reason I use MPIO with only 1 path is
so that I can maintain a consistent configuration across systems,
don't need to worry about who has one path or who has 2 or who
has 4, treat them all the same, since multipathing is automatic.
On CentOS 4.x with software iSCSI I didn't remove the paths I just
let them go stale. I restarted software iSCSI and multipath as
part of the snapshot process(software iSCSI is more solid as far
as restarting goes under 4.x, had two panics in 6 months with multiple
systems restarting every day). Thankfully I use LVM because the device
names changed all the time, at some point I was up to like /dev/sddg.
But if your removing dead paths, or even restarting multipath on
a system to detect new ones I have not had this have any noticeable
impact to the system production or not.
I think device mapper will even prevent you from removing a device
that is still in use.

The ``convert'' program from ImageMagick will do pretty much anything you want including scaling, conversion from one image type to another, combining multiple images into PDF or fax/tif files, etc. It is far better to e-mail links to files on a web or ftp site than to send the images directly.

Thank you, to everyone who responded and for all of the ideas! ImageMagick seems to be one way to go. Posting them to Picasa online, the other way. I agree that emailing them to everyone wastes a lot of bandwidth. I must make them available to the Webmaster of the official web site and one of the chorus singers (a serious amateur photographer) has a blog and he wants them. And now I have people who participate in the forum who want them to. If I can get them posted on Picasa for free and they can download any of them they like, that's the best way probably and the easiest for me. I was standing about one meter from the stage, so I have some very good photos, along with some bad ones. Thanks again! I will check out how to get them uploaded to Google's Picasa, since I have Picasa installed. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Bash Script help...
Hi All, I need to write a script that I will manually start (or a cron job in future) but I need it to do a number of things in order one after another. How do i do that so everything gets dont as the steps depend on each other. Example: cd /system_backups/ tar cvf apache-conf.tar /etc/httpd/conf/* gzip -v9 apache-conf.tar tar cvf apache-data.tar /var/www/* gzip -v9 apache-data.tar then last step... tar cvf -system_backup.tar the gzip files above gzip -v9 -system_backup.tar scp -system_backup.tar.gz u...@10.0.0.1:/. etc...etc My questions: 1. How do I execute each statement and make sure subsequent statements are not executed until the previous is done? 2. How do I error check so if a step fails the script stops? 3. Since I run an SMTP Server on this box can I e-mail myself from bash the nightly results? 4. when I want to run the scp to send over the file to another machine for safety, how can I have it know the password to the machine I am scp'ing to? My mind is going crazy sort of with the things that I could do to protect myself in case of a system failure and making restoring easier.

This will happen on its own unless you intentionally force a command
into the background with &.
>

You can use && or || or check the status of $?. For example:
tar cvfz apache-conf.tar.gz /etc/httpd/conf/*
if [ $? != 0 ]; then
echo "Error creating tar file."
exit 255
fi
$? contains the exit code of the previously executed command.
Or something like...
tar cvfz apache-conf.tar.gz /etc/httpd/conf/* || \
{ echo "Problem creating tar file."; exit 255; }
The first method is probably a little more clear.

Sure. If you call it from cron, anything on stdout will be emailed to
the user running the job. Alternately you can call the "mail" command.
You can also surround several commands and pipe their output to a
command:
(
echo "Test"
echo "Test 2"
) | mail em...@email.com

You'll want to set up ssh keys for this.

Use the '&&' (logical "and") operator to pipeline the commands: cd /foo/bar && tar cvf /path/to/tarball This will only execute the "tar" command if the previous "cd" succeeded. > 2. How do I error check so if a step fails the script stops? Most commands set a return status upon completion or error; this value is returned to the shell in the "$?" variable. You could write the above as something like: cd /foo/bar if [ $? -ne 0 ] then echo "cd failed ($?) - bailing out" exit 1 fi tar cvf /path/to/tarball if [ $? -ne 0 ] then echo "tar failed ($?) - bailing out" exit 2 fi This checks the return status of each command, checks to see if it's not 0 (0 is "success") and if it is not alerts the user and exits with it's own error status. > 3.

Commands in a script execute sequentially unless you explicitly use an & to put them in the background. > 2. How do I error check so if a step fails the script stops? Each command will return a status in the $? variable that you can check. The shell philosophy is that there are lots of ways to fail but usually only one way to succeed, so the value 0 represents success, anything else is failure. You can use the 'test' operator (usually written as [, but read the test man page to see what it does), or just: command1 && command2 (runs command2 only if command1 succeeds) command1 || command2 (runs command2 only if command1 fails - you can exit this way) > 3. Since I run an SMTP Server on this box can I e-mail myself from > bash the nightly results? Yes, cron will automatically mail any output to the user that owns the cron job. Just add an alias for this local user (probably root) to make it go where you want. > 4. when I want to run the scp to send over the file to another machine > for safety, how can I have it know the password to the machine I am > scp'ing to?

You'd probably be better off running something like backuppc (http://backuppc.sourceforge.net/) instead of rolling your own.
