Emailing from Command Line
by Mark Schoonover 14 Jul '06

14 Jul '06

Thanks for reading, I need certain shell scripts to email me after they are done running. I've installed ssmtp to forward to my internal SMTP server. I have a working ssmtp config on a Gentoo system that works just fine, but on CentOS it's not working. Here's a bounce message: Date: Thu, 13 Jul 2006 13:33:22 -0700 From: Mail Delivery Subsystem <MAILER-DAEMON(a)backups.amgt.com> To: <root(a)backups.amgt.com> Subject: Returned mail: see transcript for details Auto-Submitted: auto-generated (failure) [-- Attachment #1 --] [-- Type: text/plain, Encoding: 7bit, Size: 0.3K --] The original message was received at Thu, 13 Jul 2006 13:33:22 -0700 from backups.amgt.com [127.0.0.1] ----- The following addresses had permanent fatal errors ----- <admins(a)amgt.com> ----- Transcript of session follows ----- 550 5.1.2 <admins(a)amgt.com>...

I've also tried turning sendmail on/off as well. Where else should I look?? A typical command I'm using to email from the shell is this: mail -s "Test de Backups" foo(a)bar.com < /dev/null ... Any help, most appreciated! Thanks! Mark Schoonover IS Manager American Geotechnical V: 858-450-4040 - F: 714-685-3909 - C: 858-472-3816

I agree that hard drives are faster, larger, and cheaper than tapes, but I can drop a tape onto a concrete floor and reasonably expect it to work afterwards. A hard drive might still work, but I wouldn't want to bet on it. -- Bowie

Minimum steps needed to get horde working with a single pop3 server?
by Drew Weaver 14 Jul '06

14 Jul '06

I installed horde/Imp via yum and I am having difficulty getting it to function with my single POP3 server. I defined my external POP3 server in imp/config/servers.php, but every time I type in a POP3 username and password into the login screen it takes me to a blank redirect.php. Anyone have any idea whats going on? Note, all I did to setup apache was change the document root from /var/www/html to /usr/share/horde Thanks, Andrew

Suspend and/or Hibernate
by Sean Carolan 13 Jul '06

13 Jul '06

I asked about ACPI several weeks ago but received no responses. Are suspend and hibernate features not supported in CentOS yet? I noticed there is a daemon for acpi: [scarolan@kalki ~]$ chkconfig --list | grep acpi acpid 0:off 1:off 2:off 3:on 4:on 5:on 6:off But how do I use this feature? Normally I'm accustomed to this being a menu option when I log out (eg, on recent versions of Fedora or Ubuntu). I noticed in /etc/acpi/events/ there is a file called sample.conf which configures the power button to attempt a graceful shutdown. How can I add a 'suspend' or 'hibernate' feature and bind it to a keyboard combination? thanks Sean

Web page development, NVU: anybody with experience?
by William L. Maltby 13 Jul '06

13 Jul '06

Hi folks, I think this *might* be a product that the CentOS-affiliated community might like to include? I decide to buy a new truck because I don't drive my 'Vette enough to justify it and I can really use a P/U. Thought I would take advantage of RoadRunner's free home page (<= 5MB) to post pics, etc. to sell it. XML, HTML, SGML, DocBook... what's a n00b to do? Still working on getting my LVM fully config'd so I can test testdisk and I find I want to do this first (could almost pay for the trk). Found nvu 1.0 here http://www.nvu.com/download.php and downloaded this http://www.nvu.com/download/linux/1.0/nvu-1.0- RedHat_and_Fedora/nvu-1.0-1.rhel4.fs.i386.rpm (kde version, non-kde also available) which is supposed to be compatible with CentOS AFAICT. It installs and starts up OK on my fully updated 4.3 (including this A.M.s mutt and php updates). Well, *that's* enough by itself to ask one of the great CentOS associated repo folks to make it available for all of us. It's intended for "casual users" I guess and if no one has anything bad to say about it, other than it's for insophisticates like myself, I'd like to see it in the CentOS community and available. Any comments? It's open, free, has some financial support from this product http://www.linspire.com/lindows_sales_intro.php. Only neg I see at the outset is that it's been a little dormant. As I use it, I'll post thoughts if anybody requests such. -- Bill

RE: [CentOS] Speaking of 3Ware/RAID/SATA/9550SX...
by Mark Schoonover 13 Jul '06

13 Jul '06

Yes, I did try to boot off a 4.5TB device. Now, the individual partitions are: / 1GB /dev/sda2 ext3 /boot 250MB /dev/sda1 ext2 (Marked as primary partition.) swap 1024 /dev/sda3 ext3 /data 4.449TB /dev/sda4 ext3 All 9 drives are RAID5 together via the 3Ware card. Tomorrow, I'll don my earplugs and create a small 1TB RAID device to install CentOS, then RAID5 the remaining 7 drives for all the data. I'l recreate the partitions above in the 1TB array, then use LVM to add the remaining 3.5TB into the LVs I need. I could also read up on array carving, that's new to me. Thanks for all the help on this, I really thought I was doing something silly with the BIOS or some other setting. Didn't realize I would be running into limits of the OS. Now, if anyone knows how to tune this thing for best write performance, that would be really cool. This server is part of a tapeless backup system using rsync. There's a good howto in the Linux Hacks book. We started from that, and it's just grown into a fully automated system that does hourly, daily and weekly backups. Plus, it sends it offsite to a colo location.... In case people were wondering why so much disk space... Mark

RPM: any better way to reinstall only certain files?
by William L. Maltby 13 Jul '06

13 Jul '06

My former primary boot disk had some bad spots appear awhile back. Damage, per rpm --verify, seems to be predominately in loss of reference files in /usr/share/doc and such as that. Being the type that wastes my own time before wasting that of others, I did a semi-careful perusal of the rpm man pages. Thought the --files or some such might offer a way ought. IIUC, nope! Seems that I can't select specific files. It looks like I could do a new install in a new root (chrooted) and then copy the files out, but I was already aware of an apparently easier way I had used years ago, rpm2cpio (easier because I can use the verify output list, slightly edited and reduced, to select the desired files. Thought "Well, it probably can do what I want, I just missed it. Maybe tutorials, HOWTOs, etc. will give the answer". So, using the TOC of each of these, I probed in vain (in that vein, it was fruitless but not painless :-). http://fedora.redhat.com/docs/drafts/rpm-guide-en/ http://www.rpm.org/max-rpm-snapshot/ http://www.redhat.com/magazine/001nov04/features/betterliving/ http://www.redhat.com/magazine/002dec04/features/betterliving-part2/ I've settled on rpm2cpio unless someone can point me in a better direction. TIA -- Bill
