Hi List, I've been working on documenting an amavisd-new, spamassassin and clamav installation for postfix on CentOS5 with regards to writing this up for the Wiki (with invaluable help from forum member WhatsHisName - thanks!). I hope to make a start on a Wiki page in the next week or so, so if anyone has any experience with this combo and would like to offer advice, tips and

Hello CentOS Docs People! I recently used the Amavisd howto to setup a couple of mailservers, which saved me from hours of searching online and reading novels of documentation. Since Ned is taking a little break from the Amavisd page, I would like to help contribute. There were a few things I'd like to add, like GTUBE/EICAR testing and SELinux config lines. My wiki username is WilliamFong.

Hi List, I'd really appreciate some recommendations for colour laser printers for use with CentOS. It's for light home use with CentOS 5 and CentOS 6 systems. Must have: 1. Colour. Quality not that important as mainly for kids school project type of stuff. 2. Ethernet connectivity - want something I can plug into the network 3. Cheap running costs - don't want to be spending a

Is it possible to build a 32-bit version of Wine on 64-bit CentOS 7 ? A curt "yes" or "no" will do. Eventually I'll RTFM for the details. Cheers, Niki --

Hi list, I've knocked up a contribution on SELinux here: http://wiki.centos.org/HowTos/SELinux I've tried to pitch it as an introduction for those not already familiar with SELinux but also hopefully a useful reference. I'm relatively new to SELinux and have covered pretty much everything I know to the limits of my limited knowledge. If folks think other material needs to be

Hi List, Would the Wiki be interested in a very simple guide to setting up postfix/dovecot? I'm no expert, but have been learning postfix recently, and would be more than happy to write one based on my own setup/experience. As there's so many different scenarios for which postfix could be configured, I'm thinking just a basic guide for a working mail server to get new users up

Hey Alain, Nice work on the updated admonitions here: http://wiki.centos.org/HowTos/Wiki/Editing IMHO they look great, and a nice improvement on the previous set. Thanks for the hard work making our wiki pages look great! Ned

Hi, I am a new CentOS user (quite familiar with Fedora 1-23+) and I decided to try a new install of CentOS on a ASUS R503U. However, I can not get hibernate to work. I try: systemctl hibenaate and I get: Failed to execute operation: sleep verb not supported Btw, the problem does not go away with super-user. I was wondering how to get around this issue. I would like the abililty to hibernate

Guys, What repo has rpms for mailscanner, clamav and spamassasin?

Hi list, I have the following entries, below, in today's log file (for yesterday, 10th May). I don't run the automated yum-updated and didn't run a yum update yesterday, and no packages were installed. Obviously the entries are old. I was wondering if anyone could offer an explanation? Thanks, Ned --------------------- yum Begin ------------------------ Packages

A few years ago, I vaguely recall some issue with RHEL needing a special license or something like that, if you had more than a certain amount of CPU's or a certain amount of RAM. Does Centos work fine for 2 CPU's, 16 cores, 32 threads, and 256 G of ram? Centos6 specifically.

Okay, thanks to all who took the time to reply. What a shame; I hadn't planned on spending Easter weekend learning to do kernel upgrades, but . . . here it goes.

Hi List, Following on in my ever expanding series of postfix/dovecot guides, I've created a page and started a SASL and SSL/TLS guide for postfix/dovecot: http://wiki.centos.org/HowTos/postfix_sasl The SASL section is pretty much complete but I am yet to start the SSL/TLS section (hope to get this done over the next week or so). As usual I'd welcome comments, particularly from those

Unless I'm mistaken, does it look like Centos 4.7 is missing an update released on December 3rd 2008? Upstream details :- http://rhn.redhat.com/errata/RHBA-2008-0989.html An updated tmpwatch package that fixes various bugs is now available. The tmpwatch utility recursively searches through specified directories and removes files which have not been accessed in a specified period of time.

List, Whilst I'm in the mood for contributing stuff, here's another little howto I wrote on securing SSH that has proved popular in the past: http://forums.pcper.com/showthread.php?t=433216 If you feel it is suitable and you would like me to contribute it to the CentOS wiki, just set up a page in the appropriate area and I'll be happy to add it.

Is there a way in Centos 7 to boot into an alternate video setup? Some distributions have an option to boot into something called VESA (or something similar). Something that might not have the fanciest features, but more likely to at least just work.

Ned, Thank you very much for the response. Great example following through on the premise. It sounds like I need to have a better understanding of the traffic patterns on my network to know the optimal order for iptables filtering rules. My brief example - Premise: I want to limit outsiders from interfering with LAN client machines. So, I have the following rules regarding forwarding traffic:

Hi Guys, Are you interested in a brief guide on how to set up postgrey (anti-spam greylisting) with postfix? I set it up today and it took me a while to get it working as the config is slightly different from that on many of the googled guides (many are debian/ubuntu based). The darn config file lives in /etc/sysconfig on RH/CentOS rather than /etc/default as mentioned in all the guides I
