I'm looking for a way to give VoIP capabilities to an existing PBX: it's made by Mitel and it's used in a small/medium environment (a few dozen phones, but the PBX has capabilities for up to 200, if i remember correctly). Any high-level guidelines on how to integrate Asterisk with a PBX that's already in use? Probably that particular PBX is not supported directly, but are there

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

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: -

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.

I'm planning to do some tests with a Wildcard TDM400P and Asterisk as a small PBX, bridging POTS and VoIP. My test system is currently running Fedora 2, based on the 2.6 kernel. I intend to use Asterisk 1.0 RC1 in the tests. While gathering information regarding how to compile the required software, i came across several issues being reported, related to the 2.6 kernel series. I'd like

Let's say I want to use a much newer kernel - even one from the future, such as the upcoming 2.6.24. :-) What would y'all smart folks do in this case, in order to avoid any possible nasty consequences? Would you import the config file from the original CentOS5 kernel into the new kernel, and let the kernel deal with the differences? I.e. have the old configuration as some sort of

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'm a Thunderbird user almost since day one, but now I'm looking for something else. For whatever reason, it doesn't work well for me - every once in a while it becomes non-responsive (UI completely frozen for several seconds, CPU usage goes to 100%) and I just can't afford to waste time waiting for the email software to start working again. My main desktop platform is Linux,

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. --

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

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

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

Following Fabian's blog post re: RPMForge being rebuilt for EL5, I've a question: Are there any compatibility problems between RPMForge and EPEL? In other words, if I enabled EPEL previously, will I be able to enable RPMForge as well without running into trouble? -- Florin Andrei http://florin.myip.org/

I'm probably missing something really simple. I've installed an RH8 IAM in AWS and I'm trying to build packages on it.

(I'm doing tests in a VirtualBox instance, so take this with a grain of salt.) If you give the VM only 512 MB of RAM, the text-mode installer kicks in. It does not prompt you to configure anything related to the network or hostname. The system boots up without a network interface configured. Also, it won't let you choose the install mode, I guess it defaults to Minimal (which is fine
