as many people are aware, many ISPs block traffic on port 25 in order to attempt to prevent spammers from using bot infected hosts on their networks. this can be a problem for people who want to run a mail server from their home connection. yes, i realize that running an email server violates the TOS of most providers but that is a discussion for another day. i personally use my email server as a learning experience but i also use it for my primary personal email. ...

continued from part 1 yesterday i received my soekris engineering net4801-60 in the mail. the unit seems to be in good condition and even came with a compactflash card and vpn1411 card which i won’t end up using. i will most likely end up selling the vpn card as i don’t use my smoothwall to create a vpn and the smoothwall os does not have support built into the kernel for a vpn card such as this anyway. ...

even though all of my parts have not arrived for my new smoothwall project, i can begin to do some initial setup. first of all, here are all of the items of which i needed to find for the project: soekris engineering net4801-60 soekris engineering 2.5" hdd mounting kit soekris engineering power supply 2.5" ide hard drive 10 foot serial null modem cable since i already have the hard drive, i can do some of the prep work by installing smoothwall. i am using an old laptop to install the os to the hard drive. luckily linux is much less picky than windows about changing hardware after installing. i downloaded and burnt a copy of the latest smoothwall 3.0 sp1. installing smoothwall is about as straight forward as things come. just follow the steps on the screen until you get to the “Network configuration menu”. since we currently do not have the correct network cards in the computer, this part is going to be overwritten later. ...

like many people, i like to tinker with all sorts of different technology including multiple operating systems as well as the different roles they can play. one of the best ways that i can do that is by using a virtualization product. i just happen to use vmware server 2.0 on my debian lenny server. vmware is one of the leaders in virtualization (if not the leader). at home, i have five virtual machines that i rely on heavily for my day-to-day operations. i have two windows server 2008 domain controllers, two windows server 2003 servers running exchange 2003 and one windows server 2008 computer i use for remote desktop and management of services. some of these services can provide a fair load on my server and i was starting to see the impact, especially from my win2k8 vms. it seems that there are a number of optimizations that are not enabled by default in vmware server. i searched far and wide through vmware kb docs as well as blogs and web forums and came up with the following optimizations: ...

i’ve decided to look more into power efficiency of my computers at home. while my power bill isn’t horrible, it could most definitely be lower. there are only a few computers that i leave running 24/7. one of them is my smoothwall. while i built that computer with power efficiency in mind, i didn’t take things to the extreme that i could have. now i want to build a solution that is closer in power consumption to your typical home router appliance. after doing some research, i found a solution that would not only be power efficient but also cost effective. the solution is the soekris engineering net4801. ...

i never thought this day would come. i’m actually going to start a blog. what it is going to be about, i have no clue. it’ll probably be more random than lady gaga’s clothing but this could be an interesting learning experience.
