64-bit

Well, I know 64-bit computing isn't new, but it is new for me. Even though I had 64-bit hardware available, I've always installed 32-bit version of the OS (linux on x86_64).

I had to deal with an x86_64 CentOS 3 server and I liked it. It just took some time to figure out how to install 32-bits packages. yum install package.arch (package.i386).

Pretty neat! I just can't say anything about the performance as of now.

milter-greylist

Hi,

A few words on milter-greylist, especially because the new version (3) is now RC6 and looks pretty stable. What are the features of milter-greylist?
Per-domain and per-user settings.Friendly networks whitelistingMulti-MX sync (database is replicated many mail servers if needed)SMTP-AUTH supportSPF records: can be configured not to impose GreyListing to messages that are SPF-compliantAccess lists with DNSblsThis last option is new in version 3. It is very nice: it allows one to configure milter-greylist to impose GreyListing if the source IP is on (configurable) DNS black lists (DNSbls).

I've installed it and it decreased the number of messages/day by about 60%. I only had to whitelist one server.

Donations

Hi,

Just a little reminder to help open-source project by donating. Almost every project needs funding and it is easy to donate. My latest donations? Mondorescue, CentOS, PfSense, UltraVNC.

PfSense Follow-Up II

Hi,

Lasts week, I installed PfSense RELEASE 1.0, and it has been running very smoothly since the install. No more crashes! It's been running for 7 days straight now and I had absolutely no problem with it, except for my VoIP config for static port (see my other PfSense posts). Thanks a lot to the PfSense team!

I just upgraded to 1.0.1 now...

UltraVNC SC

Hi,

I've been using UltraVNC for a while and while commenting on an article on UnixTutorials, I thought it would be a good idea to share my knowledge. First, I must say that UltraVNC is a free version of VNC that has more features than the free version of RealVNC (thanks for sharing the code, though...). It supports encryption and Active Directory authentication, and a few other nice features.

But what I want to talk about today is the Single-Click feature (SC). Very useful... Example situation: One of your client went to a foreign country and he wants to configure the e-mail client of a laptop he borrowed there. VNC is not installed. You can spend an hour telling him over the phone how to configure Outlook or Thunderbird, or just tell him to go to your website, download a single executable, and take control of the PC and configure it.

How to proceed:


Make sure the VNC (or UltraVNC, for the rest of the text) viewer is loaded on your computer, in listen mode. You can access a sh…
