Port-Forwarding With rinetd On Debian Etch

"This article shows how you can do port-forwarding with rinetd on Debian Etch. rinetd allows you to forward ports from one system to another. This useful if you have moved your web sites to a new server with a different IP address. Of course, you have modified your DNS records, but it can take a few days until DNS changes become effective, and that is where rinetd comes into play. If clients still use the old DNS records, rinetd can redirect them to the new server. With rinetd, you do not have to fiddle with iptables rules."

FreeBSD: 7.1-BETA & 6.4-BETA Availables

"The FreeBSD 7.1-BETA and 6.4-BETA builds are now available on the FreeBSD FTP mirror sites. This is the first step in the release process for FreeBSD-7.1 and FreeBSD-6.4. This set of builds do not include pre-built packages. The ISOs are available from:

ftp://ftp.freebsd.org/pub/FreeBSD/releases/${arch}/ISO-IMAGES/7.1/
ftp://ftp.freebsd.org/pub/FreeBSD/releases/${arch}/ISO-IMAGES/6.4/

where $arch is one of alpha, amd64, i386, ia64, pc98, powerpc, or sparc64. For the Tier-2 architectures ia64 and powerpc only the 7.1-BETA builds are available. For the Tier-2 architecture alpha only the 6.4-BETA builds are available.

We encourage people to help out with the testing. Problems can be reported through Gnats or on the freebsd-stable at freebsd.org mailing list. At this point we expect the 6.4-RC1 builds to start in about two weeks, and the 7.1-RC1 builds a week after that."

Simple Easy Parallel Processing in PHP

The proliferation of multicore CPUs and the inability of our learned CPU vendors to squeeze many more GHz into their designs means that often the only way to get additional performance is by writing clever parallel software.

One problem we were having is that some of our batch processing jobs were taking too long to run. In order to speed the processing, we tried to split the processing file into half, and let a separate PHP process run each job. Given that we were using a dual core server, each process would be able to run close to full speed (subject to I/O constraints).

Here is our technique for running multiple parallel jobs in PHP.

pfsense and Smoothwall

So heres my dilemna for a project I'm working on.
I need a rather broad solution covering DNS, proxying, firewalling, VPN (both site to site and LDAP integrated user access), DHCP, supporting multiple DMZ servers along with routing support. This will act as the centre point for a 40 person network. Clearly hardware wise this will have to be quite a strong system, with load balancing being a possibility, at minimum hardware failover.

For the network security class we got asked to take a look at two firewall solutions, so whilst comparing them I also tried to see how well they would fit into the above requirements.

The firewalls looked at were pfsense and Smoothwall Express 3.0.

NetBSD 5.0 preview: User visible changes in NetBSD-current

"I've found a bit of spare time upgrade a NetBSD 4.0 system to NetBSD-current (4.99.69), and during the usual update procedure (boot new kernel; build.sh install=/; etcupdate) I found a number of user-visible changes over NetBSD 4.0 that I'd like to spotlight here."
