Fix network problems
Sometimes the network configuration makes trouble. This ist mostly caused by the Linux operating System. In
some cases the operating system renames the networkadaper and the webinterface isn't able to reconfigure the
adapter. This happens in the EMF Monitor smaller than version 0.3.3-1. To fix the problem you should update the
EMF Monitor software to a version higher or equal 0.3.3-1.
How to get a internet connection if this happens?
You have the possibility to configure it manually to get a connection for the update.
1. Open a terminal window ( press start menu -> choose terminal )
2. In the terminal enter the command
ifconfig -a <press enter key>
. With this command you'll get an
overview of the the available ethernet adapters
3. Took the name of first ethernet adapter in the list which starts with eth (eth0, eth1,eth3...).
4. Open a file manager (shortcut on the desktop -
File System
) and navigate into the folder
/var/www/
Symfony/src/Aaronia/RSABundle/Resources/config/
5. Open and edit the file interfaces_ipv4. Replace the two eth0 values with the name you find before.
Example original:
auto eth0
iface
eth0
inet static
address 192.168.178.33
netmask 255.255.255.0
gateway 192.168.178.254
dns-nameservers 192.168.178.254 8.8.8.8
Example modified:
auto
eth2
iface eth2 inet static
address 192.168.178.33
netmask 255.255.255.0
gateway 192.168.178.254
dns-nameservers 192.168.178.254 8.8.8.8
Save the changes in the file and make sure that the IP address, subnet mask and gateway addess and
dns-nameservers are correct.
6. Next step is to activate the new configuration. Please go back to the terminal window and restart the
networking with the following commands:
sudo ifdown
eth2
<press enter key>
sudo ifup eth2 <press enter key>
You'll be asked for the root password (default password is aaronia).
7. Now you should have a working internet connection. Test it with the webbrowser.
8. Open the webinterface of the RSA by entering localhost into the address bar of the webbrowser. Login in
and navigate to the page System Configuration -> System Updates . Press the Download & Install
Update button.
