Build a Soekris / m0n0wall Firewall ... Posted by Preston Moore

Comments (0) Trackbacks (0) Build a Soekris / m0n0wall Firewall ApplianceParts List Soekris Net4521 SBC Compact Flash card (8 megs or more) m0n0wall "net45xx" image physdiskwrite utility Installation Installation is very easy and you can be up and running in five minutes. First, make sure you have a copy of the m0n0wall image and the physdiskwrite utility on your Windows desktop. Plug in your card reader and insert your Compact Flash module. To copy the m0n0 image to the CF card, you simply "drag" the image and "drop" it onto the physdiskwrite utility icon. This should cause the utility program to spawn a windows shell which will allow you to choose the destination of the CF card. Choose the destination associated with your CF card and the utility will transfer the image in a flash. This completes the software installation. It doesn't get any easier than that! Sunday, September 23. 2007La Fonera, La Serial PortI never had a single user for the entire two years I had my La Fonera connected. Granted I live in a residential area, but I would have assumed with all the new construction around me I would have had at least one client. Ok, not big deal. I still have the Linksys-built, La Fonera router that only set me back five bucks. The problem was the original FON firmware is very limiting. A Google search found that the La Fonera could be reflashed with the wildly popular DD-WRT firmware. Flashing the DD-WRT firmware is simple with the added serial port. I followed the guide found here at the DD-WRT WIKI. The baud rate setting will need to be changed to 115200 after flashing to DD-WRT. The screenshot on the right is of the Windows HyperTerminal program and shows the command-line login screen after the DD-WRT flash. Also note the screenshot shows the "cpuinfo" of the La Fonera. The modifications to the La Fonera router turn what would be a very limited piece of hardware into something that is usable. The device is limited by its single ethernet port, but I intend to mainly use mine for creating a wireless bridge. Saturday, July 7. 2007The $10 Network CameraI was digging through a box of junk and found an old Logitech Quickcam Express. I started to throw it away, but wanted to see just what could be done with the archaic device. A little google-searching turned up a link to "webcam_server" which is a small Linux based program that allows you to view the Quickcam from a web browser. The installation is straight forward using the proper Linux Quickcam drivers. I wrote the install script for Centos, but you could modify it for other Linux flavors. 1) Download the Centos4 "Single Server CD" (it's 580 megs). 2) Install the "Minimal" software packages. 3) yum -y update && reboot After the reboot, plug in the Quickcam to the USB port and check to see if the system recognizes it by entering lsusb at the linux prompt. You should see the Logitech camera listed. If it does not show up, fix the problem before continuing. 4) wget http://www.prestonmoore.com/images/ezwebcam.sh 5) sh ezwebcam.sh The Quickcam driver installation asks a bunch of questions. I just hit "Enter" for all of the prompts. 6) nano +10 /var/www/html/webcam.html Change "http://localhost:8888" to the IP of your server "http://xxx.xxx.xxx.xxx:8888" Now open a web browser on a network computer and enter this line => http://xxx.xxx.xxx.xxx/webcam.html (the IP of the machine with the cam server for the "xxx") Remember the browser must be Java enabled for the applet to run. You should have a live webcam running like this. The default frame rate is set to one frame per second. You can change this by entering: nano +11 /var/www/html/webcam.html Change the FPS value="1" to FPS value="40" (this will set the Quickcam to use maximum frame rate) Almost forgot to mention webcam_server is started by issuing webcam_sever -s at the prompt. Check webcam_server -h for a list of settings. Need a cam? The Quickcams are all over ebay for $5- $10. 11-9-07 I noticed on a new Centos 5 install the script failed for some reason. If you are having problems successfully executing the script just use the "cut and paste" method. Here is the contents of the "ezwebcam.sh": yum -y install gcc httpd kernel-devel libjpeg-devel cd /usr/src/ wget http://easynews.dl.sourceforge.net/sourceforge/qce-ga/qc-usb-0.6.5.tar.gz tar xvfz qc-usb-0.6.5.tar.gz cd qc-usb-0.6.5 ./quickcam.sh echo "modprobe quickcam" >> /etc/rc.d/rc.local modprobe quickcam cd /usr/src/ wget http://umn.dl.sourceforge.net/sourceforge/webcamserver/webcam_server-0.50.tar.gz tar xvfz webcam_server-0.50.tar.gz cd webcam_server-0.50 ./configure make make install mv /usr/src/webcam_server-0.50/src/client/webcam.html /var/www/html/ mv /usr/src/webcam_server-0.50/src/client/applet.jar /var/www/html/ echo "webcam_server -s" >> /etc/rc.d/rc.local service httpd start chkconfig httpd on webcam_server -s Saturday, December 9. 2006Centos wireless for $5![]() I was at Microcenter the other day an noticed they were selling Gigafast USB Wireless adapters for $5.00 after rebate. I bought one after checking to make sure it was linux compatible. I got home and found the chipset was acutally "zd1215", not the 1211 like the driver info showed. I also found that the driver would not compile on my Centos 4.4 system. I was able hammer out the problems with some help from theloveoflinux. I have only tested this on the Gigafast dongle, but it should work for any 1211b chipset. cd /root/ wget http://www.prestonmoore.com/images/usbwifi sh usbwifi That should do it for the driver installation. The configuration will take some experimentation, but it is not that difficult. I followed the guide written by Ward Mundy here. This is all I had to do to get my system running. netconfig --gateway=192.168.1.1 --ip=192.168.1.77 --nameserver=192.168.1.1 --netmask=255.255.255.0 --device=wlan0 service network restart then I add the following line to /etc/rc.local file: iwconfig wlan0 mode Managed essid "COHNET" key 8367b179c997675f4696969696 That's it. Your system will now connect on boot. The rebate on the Gigafast USB wifi adapter ends 12/31/2006 Sunday, November 26. 2006
Asterisk/Freepbx basic Centos ... Posted by Preston Moore

Comments (10) Trackback (1) Asterisk/Freepbx basic Centos Install Guide![]() I was looking through the web stats and saw that the Freepbx on Centos guide is still very popular. I guess people are getting back to the basics and really don't need all the extras. I updated the guide to install the latest stable releases of Asterisk and FreePBX along with making it executable for easier installation. I tested the script several times and all appears to be working fine. Here we go: 1) Download the Centos "Single Server CD" (it's 580 megs). 2) Install the "Minimal" software packages. 3) yum -y update && reboot 4) wget http://prestonmoore.com/images/guide.txt 5) sh guide.txt That should do it. Reboot and you should have a working system. Enjoy UPDATE 7-6-07 I have had a ton email requesting that I update the script. Here is the new version, but there is a bug in the freepbx 2.2.2 installer that will add a couple of steps to the install. I read the bug is fixed in the yet to be released 2.3 version. Until then we have to add a couple of steps. Anyway, the software packages are the latest as of 7-6-07. 1) Download the Centos "Single Server CD" (it's 580 megs). (I tested this on Centos 5 and it works fine) 2) Install the "Minimal" software packages. 3) yum -y update && reboot 4) wget http://prestonmoore.com/images/guide070607.txt 5) sh guide070607.txt You might see errors when you get to the freepbx installtion. Just continue anyway. Also, dont reboot when the script is finished. Continue to step 6. 6) chown root:asterisk /etc/amportal.conf 7) asterisk (may have to press "enter" to get to the prompt again) 8.) cd /usr/src/freepbx We have to run the installler again 9) ./install_amp Your done. Like I said, not pretty, but it does work. Thursday, November 23. 2006
How to keep track of your servers uptime Posted by Preston Moore

Uptimed is a simple program that allows you to track the uptime of your server. It is easy to install and works great.
![]() Here's how: cd /tmp wget http://podgorny.cz/uptimed/releases/uptimed-0.3.9.tar.gz tar xvfz uptimed-0.3.9.tar.gz cd uptimed-0.3.9 ./configure make make install Now issue the following: uptimed -b uprecords You should see a display of your current uptime similar to the above image. Now we want the program to start at boot, so per the INSTALL doc in the package: nano /etc/rc.sysinit ---add the following to the end of the file echo "Creating unique uptime daemon bootid..." /usr/local/sbin/uptimed -b nano /etc/rc.local ---add the following echo "Starting uptime daemon..." /usr/local/sbin/uptimed There are other settings available in the config file. You need to move the file to /etc/ cp /tmp/uptimed-0.3.9/etc/uptimed.conf-dist /etc/uptimed.conf Happy T-day |
