It is easy to make a backup of your SD card on a Macintosh. All the programs and utilities you need to do it, are included with OS X. You will need to use the terminal, which works very much like the bash shell on the node itself. Terminal is found in the Applications/Utilities folder on the Mac.

Since this has been needed from time to time, and we finally had K9DC and Doug as well as myself KF7QLH compile a list of instructions for 3 different platforms, I thought I would put them into one “easy to search for” message. This is how you make a BACKUP OF YOUR PiRLP node. Yes, A BACKUP. It is required. Just like cars, they need gas AND OIL. You need a running version of your SD card, and a BACKUP!!!!

In the previous article I wrote we discussed making a backup of your PiRLP SD Card in this article we are going to burn that image to a new SD Card. Here are those steps... Steps: * Prepare your new SD card by inserting it into your computer or SD card reader device.

On a specific reflector: Add a special entry into the file /home/irlp/custom/custom_decode, which adds the “notimeout” flag to the call. The line would look like this: if [ “${1}” = “9198” ] ; then ${SCRIPT}/connect_to_reflector ref9198 notimeout ; exit 1 ; fi

While not an official topic relating to IRLP it is a frequent discussion on the boards. I have taken the liberty of scouring the Yahoo! boards to kind of seed this listing. One major thing to keep in mind is that while each of the following have been known to be compatible solutions you need to check the portable router…

These instructions will help you to make your IRLP Node a lot more secure! What we will do here is tell the IRLP node to lock out further attempts at access the Secure Shell (SSH) if someone or something tries to many times with the wrong password. So a bot is walking along and he decides to guess your password and after he guesses wrong say 4 times he is locked out from trying again for 30 minutes. This will prevent attackers from using millions of combinations to guess the password. So her…

This is taken from the “IRLP Operating System Upgrade Manual”... Backing up your existing IRLP node: The first step is to backup your existing IRLP node. This process has been made easy by utilizing a couple of simple scripts, and then transferring the backup file from your node using the network or a USB stick. The script only backs up files that are custom to your node. It does not include the base IRLP software, and does not backup the rc.irlp IRLP startup script, as the older versions of t…

Powering your Pi The power supply for the Pi is a very important part of its stability and operation. If the voltage seen AT the Pi board is too low, you will have issues, particularly with the network adapter (which is powered from the USB system). It will trip and make your Pi look like it has crashed if you only access it from the network side.

Record your audio files. To record the audio files, which identify your node to others, you must use a sound recorder. The windows sound recorder works quite well (sndrec32), although using an advanced one is much better. Some options of advanced sound recorders are Sound Forge and CoolEdit.

How to properly reformat your Pi's SD Card What if you have a corrupted SD or you would like to reburn an image to an SD Card previously used on your Pi? well then you probably would like to reformat it to make it clean again. In Windows this can be a bit tricky because once used for the Pi it will likely show Windows that you have a smaller SD card than is actually the case. Have no fear this is normal! Windows tries to only touch what it knows and since only a tiny portion of the SD card …

**Downloading and Running the Re-Install Script from the Server** The re-install script must be downloaded to your computer from the server. This will ensure you have the latest version of the re-install script, as it changes all the time as new versions of IRLP and Linux are released.

Performing a Re-Install WITHOUT a Backup If you want to retain your node number then this will be a bit more tricky in that you have to have a backup in order to have the “PGP Keys” that were generated at the time the original node number was assigned. So the IRLP Installs team will need to be directly involved.

Securing Remote Secure Shell (SSH) Access If you need to login to your node using SSH remotely, the following will help you avoid unauthorized access to your node. Exposing the default SSH port 22 to the internet and leaving root logins enabled (the default in the CentOS IRLP build) is not a good practice and will attract a constant barrage of attempts to gain access to your system. If you have a weak root password set, it can be a matter of hours until something or someone has gained access.
