Dial Install on RPi2

This assumes you have already completed the correct steps in your allstarlink.org and echolink accounts.

 

This install is very easy and the most difficult part of the whole install was finding the default password for the fresh install (username:root password:debian).

 

Download the Dial image from http://www.allstarlink.org for the RPi2. Then use a program like Rufus to write the image to your microSD card. After this is complete you will be able to place the card in the Pi and turn it on. After you login (username:root password:debian) there is a default script that runs. I think it has you change your root password and then runs through the basic Allstar setup asking for your Allstar login and details. It may ask about your networking and whether you are DHCP or static but this is easily changed later in /etc/network/interfaces or you can also set a static lease in your router.

 

After the script is finished and the Pi reboots you should be almost ready to go. The default ssh port for Dial is 222. I find this annoying and I don’t open ssh to outside world so I changed it back to the default of 22. This can be done in /etc/ssh/sshd_config. I then added my public key to /root/.ssh/authorized_keys so I don’t have to use a password to login via ssh and it is also more secure. You don’t have to do either of these for your system to work. These are just my preferences.

HamTalk-Logo2

 

Check out the new HamTalk website, it is now live.

It is not exactly easy to add a new user to Nagios but this is how it can be done.

 

If using ubuntu you will need to modify /usr/local/nagios/etc/cgi.cfg

The important one to view the information on the web interface is “authorized_for_system_information”.  It should look like this if you are adding multiple users.

authorized_for_system_information=nagiosadmin,cbrown,jcutright

There are more fields that you can use.  These are all the categories that nagiosadmin (the default account) is in.

authorized_for_configuration_information
authorized_for_system_commands
authorized_for_all_services
authorized_for_all_hosts
authorized_for_all_service_commands

Of  course they had to change the way you restart interfaces in Ubuntu 14.04.  Here is how to restart your interface.  Make sure you select the correct interface, the example below is for eth0.  You can check you interface name in ifconfig.

ifdown eth0 && ifup eth0

To add DNS after adding a static IP you will need to set your name servers in /etc/resolvconf/resolv.conf.d/base

Example:

nameserver 8.8.8.8
nameserver 8.8.4.4

Update resolvconf

resolvconf -u

Then restart resolvconf for shits and giggles

service resolvconf restart

GnuTLS can’t use an encrypted key file.  To create a duplicate key file with no encryption.

 

openssl rsa -in server.key -out server-insecure.key

 

It is also best to set your keys to 400 and your certs to 444.
