similar to: Simple postfix/dovecot guide?

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. Regards, Ned

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

Hi List, I have been asked in this thread if I would contribute an article on iptables to the Wiki: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=10240&forum=37 The article would be based on a tutorial I have previously written here: http://forums.pcper.com/showthread.php?t=432469 I'm not sure where the article should best go so leave that to your discretion. If you

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

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

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 Karanbir, everyone I've only just noticed that the sections on Reporting, Multiple MX Considerations and Whitelisting on the Postgrey page are specific to postfix/postgrey. I remember we previously talked about making that page less specific to any particular MTA, and Steve has since kindly contributed a section for sendmail. So I'm wondering how we could best restructure the page

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

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

Hi List, I've just drafted a FAQ/mini-HOWTO on becoming root as this is a topic I see come up time and time again. Perhaps someone with a reasonable understanding could check it for technical correctness, and if anyone would like to offer comments/feedback?? Any suggestions as to where might be an appropriate home for this on the Wiki? Regards, Ned (attached below)

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 Folks, Just wondering what Thunderbird users are doing on el7 now it's been removed from the distro? I note EPEL has a thunderbird package but it seems very out of date at version 24.5.0. Version 24.6.0 was released 10 June, nearly 6 weeks ago, and fixed 3 critical security issues. Is this normal for EPEL to be so far behind on security updates? The other alternative seems to be running

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 all, Akemi and I have recently been drafting a few posts for a new forum subsection (Readme First & FAQs) to aid new forums members in getting help. One thing we have noticed is that there are two FAQ repositories, one on the main site and one on the Wiki. Main site FAQs: http://www.centos.org/modules/smartfaq/ Presumably it would be preferable if there was just one, and as the main

Hi list, As the author of the Postfix howto: http://wiki.centos.org/HowTos/postfix I'm receiving some feedback that some things have changed in el6 (e.g, dovecot confs). As I don't have any plans to update my mail server to el6 (I intend to run el5 until EOL), does anyone have any interest in documenting changes for CentOS6 once released? On a wider note, have we given any thought

Hi list, I have a requirement for a mail server that only allows email to pass with a particular word in the subject line. Reading the header checks docs for Postfix I thought I may be able to add this rule: !/^Subject: .*dingdong/ REJECT Need to add dingdong to subject line to send Which should reject all mail unless the subject line contains "dingdong". Unfortunately this seems to

Hi List, The hardware list page on the Wiki: http://wiki.centos.org/AdditionalResources/HardwareList says: "I'd like to see this page as an entry point for hardware that does not work with CentOS out of the box or only with some effort. I do not see a need for a list which states all working hardware." I'd like to ask if we can make a small exception to that rule for
