I installed postfix with dovecot and mysql but I faced some problem...

 

First of all it seems like when I am starting the postfix process it's taking 20%wa ...

 

Than when i'm trying to send message from gmail to my mail box it seem to reach fast to the /var/spool/postfix/incoming/... but it's not coming to the defined mail dir in /home/vmail/domain/mailbox... Until I restart the postfix than it shows up there and it happens again and again, sometimes it reachs without restart but it takes quite long time. It's not problem with the server connection or speed because it arrives the spoll directory very fast so it might have somthing with the postfix process that stuck?

 

Another thing, when I try to send message to someone like gmail.com or other host it says relay host denied , how do I open all relay host? not just few I set manually.

 

Thanks very match!

 

Dovecot 1.0.7, Postfix 2.3.3-2.1.centos.mysql_pgsql.x86_64, MYSQL 5, postfixadmin in CentOS 5.0

 

This is my postfix config main.cf:

Now this is interesting. Microsoft developer Garrett Serack has acknowledged that it is generally easier to roll out a, for instance, complex stack of open source server software on Linux than it is on Windows. He also offers a solution - he's working on a project to bring package management to Windows. This project will be community-driven, and Serack has the full blessing from Microsoft.

Primarily this post was originally going to be for my own use, but i think that the community at large will be able to benefit from it.

 

There will be an update to this at some point in time as the installation that i have here is far from perfect but it will give you a good starting block on how to get Railo up and running quickly and efficiently.

 

Step 1: – Gather all the required elements to make this work.

 

1. This blog post for instructions (Duh!)

2. You will need Java JDK (Java development toolkit) ( will be refered to simply as JDK ) – The JRE Installation on its own is unfortunately not sufficiant enough to beable to run railo. – The latest version available will be suitable to run Resin and Railo ( At the time of writing the latest version was 1.6.0 U19 )

3. You will need a copy of Caucho Resin ( http://www.caucho.com/download/resin-3.1.10.tar.gz ) – For this installation i selected Resin 3.1.10 ( latest )

4. You will need a copy of Railo ( http://www.getrailo.org/down.cfm?item=/r...ars.tar.gz ) – The version that has been selected for this installation is Railo 3.1.2 ( latest )

 

The above components are listed as they are what i have used on my installation.

Red Hat has updated its virtualization platform, Red Hat Enterprise Virtualization, to include support for desktop virtualization. The beta version of REV 2.2 will include a number of new programs that will allows customers to run a virtualized desktop infrastructure.

 

"It will allow you to deploy a RHEL [Red Hat Enterprise Linux] desktop, or Windows XP, or Windows 7, on a secure high-performance hypervisor platform," said Andrew Cathrow, who is a Red Hat senior product marketing manager. "By using a VDI, you are moving the [operating system] from the end user's device into the data center, where it is easier to manage and maintain."

 

REV is a package of a number of different Red Hat applications integrated for offering virtualization capabilities to the enterprise. It comes with a virtualization management console, as well as a bare-metal hypervisor, the Kernel-Based Virtual Machine (KVM). KVM is also included in Red Hat Enterprise Linux (RHEL). REV can run hosted versions of either Linux or Windows.

The GNOME team has released version 2.30 of their open source desktop environment. "The GNOME Project's focus on users and usability continues in GNOME 2.30 with its hundreds of bug fixes and user-requested improvements. The sheer number of enhancements makes it impossible to list every change and improvement made."

 

There's a bunch of changes in this new release, obviously. The Nautilus file manager has received some love, including some user interface changes. Nautilus now also has a split view (finally), and now no longer defaults to spatial mode, preferring browsing mode instead. Yes, vanilla GNOME still defaulted to spatial mode. I love spatial mode - don't get me wrong - but the rest of the world doesn't. I was surprised it was still the default.

 

Empathy, GNOME's instant messaging application based on the Telepathy framework, has also been updated. IRC support has been improved, and a new information bar will popup when an account fails to connect, including a nice reconnect button.

Hi

 

I have been looking for documentation on the available boot options or "cheat codes" when booting Linux There appear to be variations, based on the distro being used at the time. Does anyone know where to find documentation on boot options that are distro independent and / or boot options for Puppy, PCLinuxOS and Zenwalk?

 

TIA

You know that clunky PC on your desk? Or under it? How about reducing it to something smaller, kinda shoebox-sized? Oh, they've done that - the shuttle PC.

 

So how about even smaller? Take a look at SheevaPlug, Linux within a PC power adapter:



Actually, that's old news..

 

Perhaps you'd like a Guruplug instead:

.

 

Oh, wait. Too large? Ladies, Gents and offspring of much smaller dimensions, I present the Picotux:



Yes, you see it right there. Network card in one end, video card in the other, socket for external power supply. Hidden between the rest is...

 

Oh, read it for yourself!

 

Disclaimer: I have no commercial connection to the above companies, nor have bought their products so cannot offer a review of their functionality. I'm just highly excited and geekily aroused at the thought of processing power being in something so small that a few of these and NAS somewhere on the LAN means I could do away with PCs entirely.

Patrick Verner has announced the release of Parted Magic 4.9, a small Linux-based live CD/USB with a collection of hard disk partitioning and data rescue utilities: "Parted Magic 4.9. Although this is mostly a bug-fix release, some other major changes were made. People didn't like that we were using Chrome, so we switched to Chromium. All the old IDE drivers were removed from the kernel and only the new framework is used now. The major difference most people will notice is that devices that used to be labeled /dev/hd* will now be /dev/sd* and all CDROMs will be /dev/sr*. Three new programs were added - mhdd, elinks, and zsync. Some changes were made to the kernel configuration and initramfs so Virtio hard disks could be used to boot Parted Magic. The fstab daemon was also fixed to support Virtio hard disks. Many other small fixes were made to the network scripts and the system in general." Visit the project's home page to read the full release announcement.

"Canonical has announced the availability of the first Ubuntu 10.04 beta release. The new version of Ubuntu, codenamed Lucid Lynx, is scheduled to arrive in April. It will be a long-term support release, which means that updates will be available for three years on the desktop and five years on servers. Although the Ubuntu developers have largely focused on boosting stability for this release, they have also added a number of noteworthy new features and applications. One of the most visible changes is the introduction of a new theme - a change that is part of a broader rebranding initiative that aims to update Ubuntu's visual identity." It might just be me, but I find the new theme ghastly. Compare this to this (my desktop). Oh, and Metacity - I can has anti-aliasing?

I have files on a hard drive and I can not access them.

 

I need help backing up the files from a hard drive. They are on a hard drive that was in my old fedora10 box. [ After booting, that computer freezes forever at the Fedora icon. So, I have taken the hard drive out and connected to an external enclosure. ] I want to access the files from an other computer via the enclosure. It seems like the files are in a logical volume:

/dev/sdc2 --> as determined by gparted

but I can not see them.

 

What should I do to access the data on this hard drive?
