NATd: Making DC++ work again

Since I installed the firewall in the server I have not tried to use DC++ but today I thought I would give it a try. Though I realized I couldnt search for anything and people couldn’t download files. After a short chat with Fredrik I realized why. I didn’t forward any ports from my public ip to the PC on the local net. So just to configure NATd to do that.

Fredrik had a natd.conf which I didn’t but it turned out it was not so hard to fix. Add or change the following lines in rc.conf:

  natd_enable="YES"
  natd_flags="-config /etc/natd.conf" 
  natd_interface="vr0"

The last line should be you public interface, the one connected to Internet.
Then create a natd.conf-file with entries that are the arguments you would give natd:

  interface vr0                               
  # Direct Connect redirect                
  redirect_port tcp 192.168.0.5:412 412 
  redirect_port udp 192.168.0.5:412 412

Now you have to start natd with the new config. If you have natd already running kill it first. Give teh following command to start natd:

  natd -a nn.nn.nn.nn -config /etc/natd.conf

where nn.nn.nn.nn is your external ip.

Different monitoring tools

I have used MRTG before to monitor some data like the uptime of my DSL link. But since its quite hard to configure I have been looking for other tools.

Today there was some discussion of bandwidth monitoring on the BF1942-linux_server mailinglist. Also monitoring game server statistics would be interesting. People on the list recommended the following tools:
– Cacti – BWBar – NTop

From before I have been recommended to look at Cricket that seems to use ”>RRDTool as Cacti does to. No its just decide which one to use:-)

Installing USB Storage Device

Today I bought a i-Boy 2.5” HDD case to put a 2.5” HD into. It connects to a computer using a USB cable. I had a 20Gb disk on the shelf and together with that case it will be a perfect storage device for MP3s. Next time someone has a party, just grab that disk on the way there and here comes the music!

So I wanted it both to plug in to my PC or anyones else. So I started to format the HD on my PC. I chose NTFS since it’s quite large disk and most people have XP today, if they dont I guess they can’t hear my music. But I also wanted it to sit on my FreeBSD server so I could stream the music to my xBox for instance.

So this is what I did to make that work. Read the comments I made to see what I actually did.

Installing Java

Yesterday while creating this blog I also tried to install Java on my FreeBSD machine. I wanted JDK1.4.1_01 as its the latest from Sun but that turned out to be impossible. It exists in the ports but I couldn’t make it run, the JVM crashed all the time. Even tried the Blackdown version as well but no luck.

So today I started with new energy and uninstalled those two and tried install JDK1.3.1 for which it exists a specific BSD patch. This went very well. One thing I got a bit irritated on was that javac isn’t accessable by default. I mean its not in the default path as javavm is so one has to update the path to include it to be able to compile. But all worked well and I successfully compiled a small Hello World program. Next to do is to install ANT so I can build larger projects.
