As FTP is a clear-text protocol, I would surely advise against leaving it on :) I only run a vsftpd server on one of my machines for the customers comfort, but that will change in the near future ! I can easily image scenarios where unencrypted traffic with usernames/passwords is disallowed. Regards, Michel

Remove all packages from specific repository
by Morten P.D. Stevens 17 Sep '10

17 Sep '10

Hi CentOS Mailinglist, we are using amavisd-new (with all dependencies) from Fedora/Redhat EPEL repo. Some packages from EPEL repo are very old. (amavisd-new, clamav, spamassassin) What's the best way to remove all amavisd-new packages (and it's dependencies) from EPEL repo and reinstall it from rpmforge repo? Thank you. Best regards, Morten

Amazon AMI based on CentOS 5?
by Mathieu Baudier 17 Sep '10

17 Sep '10

Hello, Amazon has just released a custom Linux distribution (Amazon Linux AMI) for use in their EC2 cloud: http://aws.amazon.com/ec2/faqs/#What_is_the_Amazon_Linux_AMI Out of curiosity, I googled a bit around it and read in various places (e.g. [1] and [2]) that it is based on CentOS 5 (basically a stripped down version) and should be compatible with most packages. Do any of you have confirmation of this? And more details/experience? (I'm not a EC2 user, so I cannot check by myself...) Thanks, Mathieu [1] http://www.cloudave.com/4872/open-source-and-cloud-computing-the-amazon-lin… [2] http://news.ycombinator.com/item?id=1693055

Firefox spelling checker
by Frank Cox 17 Sep '10

17 Sep '10

I just noticed that since the last updates, Firefox no longer does the automatic spelling checking thing in text boxes. I'm sure that it used to work and I'm not sure exactly when it stopped. I just tried it on two different up-to-date Centos 5 machines with the same results. "Check my spelling as I type" is set. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Can anyone suggest a decent backup system?
by Kevin Thorpe 16 Sep '10

16 Sep '10

Hi all, We have a bit of a problem with backups. We've been using bacula to tape and now trying to disk but it's a complete nightmare as regards tape management. The backup to file storage went ok for ages and now is stuck 'waiting for max storage jobs' which is odd as that's set to 20 and it's the only backup running. That's totally typical of bacula. Can anyone suggest a simple backup package for us? Essentially a single server, full backup to tape every day. We don't need tape management as we're fully capable of reading the written label on the tape ourselves.

is Intel VT-d "really" necessary?
by Rudi Ahlers 16 Sep '10

16 Sep '10

Hi all, I'm just curios and would like some input from the community on this one. We're busy budgeting for a couple of new servers and I thought it would be good to try out the Core i7 CPU's, but see the majority of them don't offer VT-d, but just VT-x. Looking at the LGA1366 range, only the "Intel lga1366 i7 980XE" (from the list of what our suppliers stock) have VT-d, and it costs 4x more than "Intel lga1366 i7 930" or 2x more than "Intel lga1366 i7 960". From a budget perspecitve I could purchase 4 more CPU's, which could translate to 40x - 80x more VM's being hosted for the same capital outlay. Experience has shown that we under-utilize CPU's by a great margin and memory / HDD IO is our biggest bottleneck on any server. So, if VT-d really necessary? We mainly host XEN virtual machine for the hosting industry, i.e. we don't need / use graphics rendering inside VM's, or need DAS on the VM's, etc. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532
