Run
systemctl restart network
in order to apply the changes
Note
: Correct network parameters settings are extremely important for normal CompletePBX
functionality.
Always make sure that the 'localhost' is defined in the /etc/hosts file:
127.0.0.1
localhost.localdomain localhost
Step 4: Configure the CXR2000/CXR3000
If the unit is equipped with FXS ports they are configured as CompletePBX extensions starting
from number 3001.
In order to configure the device follow these steps:
a)
From a computer’s Internet browser enter the CXR2000/CXR3000 IP address (for example
http://192.168.0.64 )
b)
You will be prompted to define a password for “administrator”. Once you define a password
you will be able to connect to the web interface as user
admin
with password that you defined.
Now you can modify your CXR2000/CXR3000 CompletePBX configuration. See the
CompletePBX Reference Guide
.
Step 5: Protect CompletePBX Against Unauthorized Access
Once you have
fully
configured
CompletePBX we highly recommend that you use the following
procedures and applications supported in CompletePBX to protect it against unauthorized access:
Change the Linux Password
The password for the Linux root user can be changed by using the Linux
passwd
command.
IP Protection
CompletePBX must be installed on a protected LAN and must not be directly connected to the
public Internet. The LAN must be protected by a Firewall/NAT router.
Intrusion Detection (fail2ban) and Firewall
In order to maximize protection from external threats, the
fail2ban
process is activated, in addition
to the internal firewall. Use the Admin|Security|Firewall and Admin|Security|Intrusion Detection
dialogs to modify the internal firewall and intrusion detection settings.
Unit Status LED (Light Emitting Diode) indicators
The CXR2000/CXR3000 is equipped with varying LED indicators on the front panel, depending on
the model.
Digital CXR2000/CXR3000 Models
These are models that have at least one digital PSTN port – ISDN BRI or PRI. They have a vertical
array of four status indicators on the left side of the front panel (
