SOLVED NOOB needs help: incrediblepbx.local issue and I need a Static IP on my Pi

oxyfiremedia · Mar 6, 2015

Ok - so everything is working great on my Raspberry pi running IncrediblePBX PI... Except Two things.

I need to set up a port forward so my IAX trunk works and so my SIP phones know where to ping (Grandstream GXP2000). I have completed this and it works great until my Pi crashes or needs a reboot. Then the Pi's IP changes via DHCP and I have to reconfigure my port forward and the IP on my 3 phones. I've tried to setup a a MAC binding IP but it's not working either. My routeris TP-Link AC750 Archer D2.

I've trawled the forums and keep seeing posts that I should not setup a static IP. When I configure a static IP in nano /etc/network/interfaces, the Pi looses connection to the net (even though settings are correct) but I can dial internal extensions. I revert it back to DHCP and it gets internet connection back again and I can make outbound calls.

Also - When I visit http://incrediblepbx.local/ all I get is a broken screen. See attached.

Please help this is driving my insane.

Ok so my second issue i've worked out...

http://incrediblepbx.local/admin/config.php

Looks like The problem is that FreePBX overwrote the index.php file in /var/www/html.

To fix I created a new index_custom.php file in /var/www/html that looks like this and overwrote the old one:

Code:

<?php  header("Location: ./admin/config.php");  ?>

And hey-presto, it's now working. But i'm still having issues with the static IP thing. Any ideas?

synack · Mar 6, 2015

when you configure the static entry, are you also defining a default gateway? Are you also defining a DNS server in /etc/resolv.conf?

oxyfiremedia · Mar 6, 2015

Hey Synack

Thanks for getting back to me... My Static entry looks like this

Code:

iface eth0 inet static
address 10.1.12.2
netmask 255.255.255.0
network 10.1.12.0
broadcast 10.1.12.255
gateway 10.1.12.254

I am NOT updating or defining a DNS server in /etc/resolv.conf.

Let me try that now!

Is it ok to use googles 8.8.8.8 and 8.8.4.4?

synack · Mar 6, 2015

Just for clarification:
/etc/network/interfaces

Code:

iface eth0 inet static
address 192.168.x.y           #Static IP for Pi, should not be the same as another. X=whatever you use for your network, often 0 or 1.
netmask 255.255.255.0    #subnet mask - usually what I have given
network 192.168.x.0          #network designation, usually 0     
broadcast 192.168.x.255     #broadcast address, usually 25
gateway 192.168.x.254        #ip address of your firewall/default gateway, usually 1 or 254

/etc/resolv.conf

Code:

search home.local         #domain DNS suffix for your network, like dude.com or home.local. in your example above you would have just: search local                
nameserver x.x.x.x          # many home firewalls provide DNS, you would select the same IP as the gateway above. otherwise try google at 8.8.8.8

oxyfiremedia · Mar 6, 2015

Ok so my nano /etc/network/interfaces looks like this

Code:

auto lo
auto eth0
 
iface lo inet loopback
iface eth0 inet static
address 10.1.12.2
netmask 255.255.255.0
network 10.1.12.0
broadcast 10.1.12.255
gateway 10.1.12.254
 
allow-hotplug wlan0
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa.conf
 
#up iptables-restore /etc/network/iptables

And my resolv.conf looks like this

Code:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#    DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8
nameserver 8.8.4.4

Yep that's fine. your interfaces look good too.

synack · Mar 6, 2015

Do you have the wlan0 active? with it configured as DHCP, DHCP will overwrite your resolv.conf.

oxyfiremedia · Mar 6, 2015

NOPE - not working

See below... no public IP

It's driving me mad

How can I check if wlan0 is active?

synack · Mar 6, 2015

try a traceroute to 8.8.8.8

Code:

traceroute 8.8.8.8

also you seem to have your hostname missing in your /etc/hosts file

Or am I being stupid? If you mean - am I using a wifi dongle in USB... NO i'm not - the only connection out to the internet is via eth0 (ethernet cable)

Thanks

dag nabbit. I don't have a pi myself so I don't know exactly what comes on your distro or not.
You can try installing i think net-utils.
again i'm guessing here on distro, but i believe its

Code:

apt-get install net-utils

or you can try:

Code:

ping -R 9 8.8.8.8

I should probably mention, you may want to sanitize any external IP addresses before posting here, for your safety.

oxyfiremedia · Mar 6, 2015

any other ideas?

synack · Mar 6, 2015

I meant -R to record route, but that's moot anyway. Looks like you are getting internet all the way to google.
the Internet issue must then be related to DNS.

I've just reopened /etc/resolv.conf and found my nameservers have vanished.

Code:

  GNU nano 2.2.6                              File: /etc/resolv.conf                                                                 
 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#    DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

What does it mean when they say
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

If not by hand, then how do we set it?

synack · Mar 6, 2015

do you have dig or nslookup?

Code:

 dig @8.8.8.8 myip.pbxinaflash.com
