CentOS / BQ / PHP 4.3.9 with the mail() function
by Jon McCauley 15 Jun '05

Hey everyone! Got a little problem...with CentOS / BQ / PHP 4.3.9 with the mail() function I'm able to send mail using postfix directly from the command line, however when I try using the mail function of php no mail is being sent. This simple script works on all my older Cobalt Boxs. <? if($action=="send") { $to = 'me(a)domain.dot'; $subject = 'the subject'; $message = 'hello'; $headers = 'From: me(a)domain.dot' . "\r\n" . 'Reply-To: me(a)domain.dot' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); mail($to, $subject, $message, $headers); ?> the queue looks like this.... Jun 14 11:47:45 bq0 sendmail[19390]: j5EFljEU019390: from=<>, size=1146, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1] Jun 14 11:47:45 bq0 sendmail[19389]: j5EFljk1019389: j5EFljk2019389: return to sender: User unknown Jun 14 11:47:45 bq0 sendmail[19390]: j5EFljEW019390: from=<>, size=3858, class=0, nrcpts=1, msgid=<200506141547.j5EFljk2019389(a)bq.ontarioservers.com>, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1] Jun 14 11:47:45 bq0 sendmail[19389]: j5EFljk2019389: to=postmaster, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=32170, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (j5EFljEW019390 Message accepted for delivery) Jun 14 11:47:45 bq0 sendmail[19391]: j5EFljEW019390: to=admin, delay=00:00:00, xdelay=00:00:00, mailer=local, pri=34070, dsn=2.0.0, stat=Sent I did a some googling and found a post http://forums.fedoraforum.org/showthread.php?t=27608 Any sujestons as what I should do .....I dont want to play with another script to get this done??....thanks in advance -- Best Regards, Jon McCauley

x11 update problems
by Rick Ziegler 15 Jun '05

15 Jun '05

Hello, I had a power outage during a 'yum update' and I think something may have gotten corrupted in the process. Trying to run 'yum update' again gives the following errors on the most recent x11 packages: Error: Missing Dependency: xorg-x11 = 6.8.1-23.EL is needed by package xorg-x11-Xvfb I've tried removing /var/yum/cache, and various yum and rpm command line options for these 2 and other x11 packages, but can't seem to get past this. Does anyone know how to re-install these latest x11 packages? I'm running CentOS release 4.0 (Final). Thanks in advance, and let me know if there's any additional info I can provide. ~Rick __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I think that's what it's going to take. Regardless, XFS is GPL, so we all benefit. Just the XFS dump, resize, etc... tools, as well as day 1 this'n that support. Just too tasty compared to the "work-in-progress" I always see on everything else. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Feature-wise, probably not. The VFS in 2.6 brings a lot of former XFS-only features to _all_ filesystems. But I still see serious size limitations as well as scalability to Ext3 versus XFS. > Yes, I've pointed out on official Red Hat mailing lists that 2 is false > due (at least) to the issue of backing up ACLs (use star they say -- no > thanks, Well, Red Hat has shipped Jorg's "star" in RHL8 on-ward to address this. > say I), but I got no response to that.

To me, I really could care less about benchmarks except when real performance issues arise. All throughout 2.4, every other filesystem -- Ext3, JFS (from OS/2**), ReiserFS, etc... required hack after hack after hack. XFS, with its "core" additions to kernel 2.4 provided _everything_ standard from day 1 -- Quotas, POSIX EA/ACLs, etc... It was ported directly from Irix, and was _entirely_ GPL -- which you'd figure that's something Red Hat likes. The only bug that it ever ran into, which resulted in XFS 1.1, was something that bit me on 2 /var filesystems. Otherwise XFS, like Ext3 but _unlike_ JFS or ReiserFS, benefits from being the _exact_ _same_ organization for 10+ years. Which means not only is its on-line operation well-trusted, but it's off-line fsck/repair as well (something that plagues ReiserFS heavily due to design focus). Because I could care less how a filesystem works when it works. I want to know what happens when its inconsistent, and a journal reply won't solve the problem. I trust e2fsck and xfs_repair. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Since 2002, this is the #1 reason I've been advocating that Red Hat adopt XFS as its' 2nd, officially supported filesystem. xfsdump for XFS does this, and always has. You don't have to use "getfacl" to save POSIX ACLs (although that was always an option, even back in the early 2.4.x days for XFS). Everything (short of SGI-integrated hardware API support) came over from Irix in XFS for Linux, and that included POSIX ACLs, Quotas, etc... This is in stark contrast from IBM JFS which came from OS/2 instead of AIX (because of the legal issues with Monterey), and ReiserFS is a non-traditional UNIX design (I won't go there, even if it is very innovative in most respects). Most of these features in kernel 2.6 ere thanx to the SGI XFS team, and the team also worked with the Ext3 and Linux & co. as of 2.5.3+ in ensuring POSIX EAs were uniform across all filesystems c/o the VFS. I haven't wanted to bother Tweedie and/or Red Hat in getting an explaination why they aren't looking at supporting XFS, but I think it would solve a lot of scalability issues. I always assumed it wasn't merely a "NIH" attitude, and they had real reasons for not wanting to support it until Ext3 proved to be a serious limitation for them. Rodrigo Barbosa wrote: > That depends very much on what you are calling extended attributes. > I have no experience with SELinux, so I really can't make an > educated guess on what you are talking about. > Care to enlight me ? I have to be honest, I've never used xfsdump and verified SELinux attributes were preserved. But it should bring _all_ POSIX EAs with it. I've just typically relied on it for ACLs. -- Bryan J.

A questiong about replacing my failing drive
by Doug Eubanks 14 Jun '05

14 Jun '05

First, I am not a RedHat or linux newbie. I simply have not had to do what I am getting ready to do, and I want to see if I am going to run into a problems... My HDA drive is failing (I can hear the occasional click from it and I am seeing Smart errors, the transfer rate is slow but all my data is there). I have 3 partitions on it, the /, /boot/ and my game servers (this is also the drive the bootloader is on). Will this proceedure work ok to replace it with the minimum of downtime/reinstalling A> Make bootable floppy B> Start in single user mode C> Create same partition structure on hew drive D> Move all files from old partitions to new partitions E> Switch drives F> Boot off floppy, mount, reinstall grub and boot manager on new drive G> Profit! Any hangups or snags doing it this way? Thanks, Doug Eubanks doug(a)simflex.com
