# 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-14-server x86_64 Ubuntu 9.04 Here's the situation: I have several local clients (Thunderbird) which do not use TLS at all. It's plaintext completely, on port 143, because the connection is local and there are no unauthorized users on this network (it's a home network). I want to keep it that way to keep things simple.

I am moving away from Cyrus, I'm trying to migrate to Dovecot. I am trying to get Sieve working with Dovecot and Postfix and it just won't work. Postfix is able to delived new messages to the "new" subfolder of the inbox structure. After I run Thunderbird, the new message gets moved to "cur" and it shows up in my inbox. So far so good. But now I'm trying to add

I looked in the yum repositories for CentOS 7 and I noticed that there are no packages for any of the major open source IPSec VPN apps - Openswan, strongSwan, etc. I'm pretty sure CentOS 6 had Openswan packages. What is the current consensus w.r.t. building an IPSec VPN "server" (concentrator, whatever) on CentOS 7, that will do site-to-site connections with Cisco hardware at

I just received a Wildcard TDM400P by FedEx yesterday. I noticed that the FXO/FXS modules use connectors similar to Ethernet. Now, i want to connect the TDM400P to the PSTN connector in the wall, and also to a regular analog phone. Both the PSTN conn and the phone use smaller connectors, typical for analog phones. I searched the "official" docs and the Wiki, there's good

If your Perl apps are unusually slow on CentOS 5, have a look at this blog: http://blog.vipul.net/2008/08/24/redhat-perl-what-a-tragedy/ In a nutshell: some Perl apps are 100x slower on RedHat / CentOS 5 compared to other distributions.

Is it possible to add caching to a pipe? cat blah | in_RAM_cache_here -s SIZE | something else I'm doing what is essentially a cat (*) from a DVD directly to an NFS share. It looks like the two media (DVD and NFS) have very different read / write behaviors, speeds and timings, and the overall process is not as fast as possible. So I was wondering if some kind of cache inbetween might be

I need a SATA RAID PCI card that works well with CentOS and is fully supported. Mandatory features: - works with the drivers already in the kernel, no additional drivers - can do RAID 0, 1 and 5 - hotswap - allows to monitor the status of the array and of each individual drive via a script (ideally run from cron) - works with very large SATA drives Nice to have features but not mandatory: -

CentOS 7 How do I print something on the text-mode console right after the OS has finished booting? I've a virtual instance and I need to know its IP address after it has finished booting up, to know where to ssh into it. I've tried adding "ip -4 addr > /dev/tty0" to rc.local, but that obviously doesn't work, because the login prompt overwrites everything I do. --

Have a look at these pages: http://www.bofh-hunter.com/2008/06/13/3ware-performance-in-centos/ https://bugzilla.redhat.com/show_bug.cgi?id=444759 I'm comparing the default 5.1 64bit kernel with the patched one posted in the bug report (kernel-2.6.18-53.1.21.el5.bz321111.x86_64) and I don't quite see any significant difference in write performance for this command: dd if=/dev/zero

I will install Asterisk on my home server, I want to be able to route video calls, but I need the Windows and Linux clients to be interoperable. On Linux, it looks like Ekiga is a good candidate. But how about Windows? Anyone using Kapanga in an Asterisk network that includes Ekiga? Are these two interoperable? I'm not necessarily looking for open source software, free for personal use is

So, my favorite RPM repository (EPEL) only has the ancient nagios-2.12 or so. What's the repo you use for Nagios 3? -- Florin Andrei http://florin.myip.org/

Anybody using hardware SSL accelerators on CentOS? The architecture that I'm looking at is CentOS 4 32 bit and Tomcat, and the motherboards can accept PCI Express cards. But I'm interested in any observations at all, even on different software and hardware versions - what works for you, what to stay away from, etc. -- Florin Andrei http://florin.myip.org/

Postfix 2.3.3 that comes with RH/CentOS is very old, there are lots of new features in newer versions that appear to be very useful (revised queue manager with better scheduler as far back as v2.5, etc.). Latest stable version is 2.7. I was looking for RPM packages and I've found this site: http://ftp.wl0.org/official/ Anybody using it? Good things, bad things?... Anybody using Postfix

I'm doing some experiments with GlusterFS. Most documents online suggest to install the glusterfs-package as if it was available directly in the repo, and therefore installable via a simple "yum install". Unless I'm wrong, it appears that this package is not in the repo for CentOS 6. Does anyone know what happened to it? -- Florin Andrei http://florin.myip.org/

I'm using CentOS5 64bit on a system with a 3ware 9650SE card. I installed the OS using the driver disk files provided by 3ware. It worked fine with the original CentOS5 kernel. After doing a "yum update", which also installed an updated kernel, the system didn't work after a reboot, using the new kernel. I rebooted the old kernel, moved the 3w-9xxx.ko file from

I'm looking at this document to convert RHEL4 systems to Yum and setup an updates repository. http://sial.org/howto/yum/ Which version of yum would you recommend for that? What would be the dependencies that need to be installed? Any guidelines for installing Yum on RHEL4 without breaking the RPM dependencies and stuff (and with minimal changes to the system)? The document recommends

http://yro.slashdot.org/article.pl?sid=04/08/04/2212251&tid=158&tid=95&tid=103 Probably some of you already saw this. Now, beyond discussions regarding the legitimacy of such a ruling (whether they have the legal, moral or whatever right to enforce it), there's the technical aspect. Suppose i provide VoIP services using Asterisk, and i fall under the incidence of the FCC ruling

Looks like there's no repo that carries the Nvidia drivers. I enabled all the big repos in /etc/yum.repos.d and did a "yum provides" and nothing showed up. Where do you get your Nvidia RPMs from? -- Florin Andrei http://florin.myip.org/
