Hackers Hub

Hackers Hub is a private hub of GMRS Radios for trusted family, friends, and individuals known to the group. Operating around the United States, it is a tight-knit group of nerds who love to dabble in radio.

While the process isn't perfected yet, the node setup is pretty straight forward. We're using an image obtained by another GMRS group and modifying it to be our own. If you have issues contact malware or gibby for assistance. The walkthrough below isn't exhaustive but its a good start. Having some knowledge in linux and how computers work will be helpful.

• Download GMRS Image from here https://www.gmrslive.com/index.php/downloads/
  • Burn to SDcard, https://etcher.balena.io/ if you need something to do that for you
• Boot and ssh in
  • default user/pass is root:root, default SSH port is 222
• First Time? Yes
  • Yes
• Change root password?
  • Change as needed
• Configure asterisk
  • Yes
• Change timezone?
  • Change as needed
• Change hostname?
  • Change as needed
• Change IP?
  • Change as needed
• Change SSH port?
  • Change as needed

REBOOT

login with root / new password

• First time astrisk configuration?
  • yes
• Enter node number?
  • This is the number given to you from gibby, NOT A NODE NUMBER FROM GMRSLIVE OR ANYWHERE ELSE
• Node number change?
  • Yes
• Node number type/is this a private node?
  • Yo
• Re-enter your node number
• Select CW or Voice: change to your preference
  • CW is morse code and Voice is a robot woman reading things out
• Set Bind port
  • leave to 4569 unless you wish to change it
• Duplex Setting
  • Semi-half
• Enter node password
  • leave blank
• IAXRPT password, do you want to configure a password?
  • No
• Review Simple USB Config?
  • No
• Restart Asterisk?
  • Yes

Enter bash shell

#crontab -e

enter your zipcode before $NODE1 i.e.:

00 0-23 * * * (source /usr/local/etc/allstar.env ; /usr/bin/nice -19 /usr/bin/perl /usr/local/sbin/saytime.pl 60606 $NODE1 > /dev/null)

Navigate to the astrisk directory

#cd /etc/asterisk

Editing the rpt:

/etc/asterisk/rpt.conf

Validate the config:

[1998] ⇒ [AssignedNodeNumber]

If 1998 is still present, find/replace 1998 with your assigned node number. In nano, this can be done using the CTL+\ command, 1998, NODENUMBER, A

If needed, add node definitions for all the other nodes on your local network.

For example, the server node is 1500, and my other node is 1501.

Example:

[nodes]

1000 = [email protected]/1000,NONE ; This is the node number assigned to you. Replace 1000 with your number number i.e., if you are node 1188 the line should look like: 1188 = [email protected]/1188,NONE

1500 = radio@<domain>:4569/1500,NONE ; This is the Hackers Hub Ensure 1500 is added, it is how you connect to the hub

save/exit

Edit iax.conf

comment out the following line to show:

;register ⇒ 1998:@register.gmrslive.com

save/exit

edit manager.conf

make the following changes:

webenabled = yes

;bindaddr = 127.0.0.1 ; Local interface only!

bindaddr = 0.0.0.0 ; Not secure

secret = SUPERMONPASSWORD ; Alphanumeric, no more than 8 characters, no specials

Navigate to sbin

/usr/local/sbin/astdb.php

Edit the astdb.php file

Change the url path from http://register.gmrslive.com/cgi-bin/privatenodes.txt to http://domain/privatenodes.txt

Execute astdb.php

#./astdb.php

Navigate to the supermon directory

#cd /srv/http/supermon/

edit allmon.ini

make the following changes

[1998] ⇒ [YOUR NODE NUMBER]

passwd = SUPERMONPASSWORD ; Alphanumeric, no more than 8 characters, no specials

[1999] stanza:

menu=no

[All Nodes] Stanza:

nodes=YOURNODENUMBER

[lsNodes] Stanza:

url=“/cgi-bin/lsnodes_web?node=YOURNODENUMBER”

[GMRS Live Status] Stanza:

menu=no

[GMRS Live Facebook] Stanza:

menu=no

Enter the command:

# astres.sh

While not needed, you can edit common.inc and global.inc to you liking. These are purely for visuals on the supermon page.

issue the following command in the web directory:

#htpasswd -cB .htpasswd admin ; Alphanumeric, no more than 8 characters, no specials

enter the supermon admin password

CTRl+D

Setup wifi to your liking. if needed (option 7)

REBOOT AND PLUGIN RADIO HAT DURING THE REBOOT

Install dependencies for serial interface for SRFRS

pacman -Sy python-pyserial

git clone https://github.com/jumbo5566/SRFRS.git

#cd SRFRS

python srfrs.py radio –frequency 462.6750 –squelch 2 –ctcss 141.3 ;set the above to your desired freq, squelch and ctcss tones, make sure its not on a freq being used locally! python srfrs.py volume –level 8 ;set to your desired volume level

exit to main menu

select option 12

change the following

J) Change COSFROM Mode (currently “usbinvert”)

L) Change CTCSSFROM Mode (currently “ppinvert”)

set radio to frequency above & configure ctcss tone

blip TX, you'll hear the radio module give you a beep acknowledgement

Open a browser and navigate to the rpi's IP address: http://IP/supermon and click login. You will want to click on the node number after you've successfully logged in for it to load the buttons.

In the connect text box, enter 1500, check Permanent, click connect
