<td valign="top"> as you can see, it really is just a basic computer. today i received the last parts that i will be needing for this project. they are the hard drive mounting kit and the power supply. i purchased these directly from soekris engineering. in part 1, i prepared the smoothwall install on a 2.5" 60GB laptop hard drive.</p> <p> the next step is to install the hard drive on the mounting kit inside the unit. the hard drive connects using four mounting screws on the bottom of the drive. the mounting kit is connected to by unscrewing the four screws which secure the net4801 to the case and placing the mounting bracket on top of the board's mounting holes and reinserting the screws into the mounts.</p></td> </tr> </table>
now that the hard drive is connected and the unit is closed back up, it is time to test the unit. in order to do that, i am going to fire up minicom on my server which is connected via null modem serial cable to the net4801 and listening on com1. if the unit does not show any activity in the minicom windows, you might want to check out the manual from the soekris download page to make sure that you have configured minicom to use the default settings (19200 baud, 8 databits, no parity, 1 stop bit, no flow control). here is the boot screen that you should see upon powering up the unit:

Press Ctrl-P for entering Monitor.
on minicom, the unit shows a ram count and then after a few seconds proceeds to boot. due to the configuration of the kernel smoothwall uses, you can’t see the boot messages (and we didn’t set lilo up to show them even if the kernel supported it). once the unit is ready, it will display a login prompt:
smoothwall Connected on ttyS0 at 19200 bps smoothwall login:
from there you need to login using ‘root’ and the password you set up in the initial configuration. once you login, you will need to reconfigure your smoothwall’s network settings. you do this by running the ‘setup’ command. on the setup screen, you will want to choose ‘networking’, then ‘network configuration type’. on the next screen, choose “green + orange + red”. you will then want to choose ‘drivers and card assignments’. then choose ‘ok’ to change settings then choose ‘probe’. as it detects the network cards, set them as green, then orange, and red (the order is important). green (internal) is eth0, orange (dmz) is eth1, and red (external) is eth2. make sure the address settings are still correct for your network and your external network is set properly for your ISP.
once that is done, i connect network cables to the net4801 and then reboot the unit. once it reboots, you might want to check to make sure all of your interfaces have ip addresses and have been assigned correctly. if they have not, you will want to re-run setup and check for errors in your configuration. from there, i was able to connect to the web interface and configure my smoothwall. now i am up and running behind my net4801. from looking at my mrtg graphs, i can get an idea of how much less power the net4801 uses. my estimated runtime on battery went from ~30 to ~38 minutes.
and that’s pretty much about it for the setup. if you have any questions, feel free to post them in the comments section.
