How to re-enable Adobe Flash in Firefox
by David McGuffey 23 Feb '13

23 Feb '13

Mozilla seems to have disabled Adobe Flash in a recent update. I have one 6.3 Desktop load that I need flash. when directed to the Adobe site and download the latest version, yum tells me I have the latest version for x86_64 already installed. I must keep the wife happy with Facebook and YouTube--and if the wife isn't happy, no one in the house is happy. How do I re-enable flash? DaveM

problem building partitionable RAID-1 on Centos-6
by Fred 23 Feb '13

23 Feb '13

Trying to install Centos6 on my system (it's been running C5 for years). I've got a pair of drives, so I'm trying to use RAID-1. Previously I used a procedure where each partition was part of a separate RAID device, but this time I'm trying the HOWTO from the Centos WIKI on making a partitionable RAID pair. I've been having a lot of problems, but have also been working thru them. but t his latest one has me stumped, I'd appreciate some advice. Booting encounters a panic when trying to mount the RAID subsystem. you can see an image of it at users.rcn.com/fredricksmith/panic.JPG. Looks as if it's trying to boot from md127. there ain't no such critter, where'd it get the idea it could boot from there? or more importantly, how can I solve it? thanks! I may have to revert to the other method, but I figured this one was worth a try. Fred

Centos 6.3 and dovecot with an abrt problem
by Gregory P. Ennis 23 Feb '13

23 Feb '13

Everyone, I have a mail server running CentOS release 6.3 (Final) with 2.6.32-279.22.1.el6.i686 kernel that is reporting errors to me pertaining dovecot. I have appended the error message to this note. There is only one user that appears to generate this message, and it is generated to me by way of e-mail without a perceptible problem to the user which is not me. This particular user had an inbox greater than 2 gigs in size, so I asked him to move or delete unwanted files, which reduced the size of the inbox to 400 megs. Unfortunately, the abrt messages have continued. I did a google search on : "usr/libexec/dovecot/imap was killed by signal 6", but did not find much that I could use to help me debug this. Can any of you point me in the right direction. ' Thanks much!!!

I really should have caught that. So I was all ready to edit grub.conf and then slapped my hand. You TEST it out first, adding the command at boot time. ARGH! Once before (5+ years back) I had to add a kernel param and did it wrong and it was a big recovery challenge. No test and verify before making permanent. Whew. So I googled the param to get its format right, and it is iommu=off. Without that dash in front. But as I read up on this option, it does not sound like something I want to globally turn off just to stop a supposedly annoying message (if they have indeed worked around it, and my new DNS server is running with this OK). So I will test from booting and typing the option in without actually altering grub.conf. But if there is a way to just stop getting this message, that would be good too. thank you all for your help. > > https://www.google.com/search?q=linux+add+kernel+params > http://www.kernel.org/doc/Documentation/kernel-parameters.txt >
