This issue affects fixed sensors (Pwn Pro, Pwn Plug, etc.) running Pwnix Release 1.9.11 or later, when using the sensor's web-based UI for configuration.

In the web-based UI, on the Name Servers settings page (under Network), the default IP address of the name server is "8.8.8.8".

If the IP address is changed to a new, single IP address, i.e. 75.75.75.75, when the Set Name Servers red-button is pressed the /etc/resolv.conf file is updated with the IP address specified and the UI is auto refreshed to reflect the newly updated IP address. This is the normal and expected behavior.

However, if the IP address is changed to multiple IP addresses (for example 75.75.75.75  is typed on the first line and 75.75.76.76 is typed on the second line), when the Set Name Servers red-button is pressed the /etc/resolv.conf file is updated with the multiple IP addresses entered, but when the UI auto-refreshes it displays the IP address provided on the second line, i.e. 75.75.76.76 only of what was entered prior to pressing the Set Name Servers button.

As a result of this unexpected behavior this issue may cause confusion and lead persons to believe they are unable to save multiple name servers when using the web-based UI. However, this is a cosmetic issue only and reviewing the contents of the /etc/resolv.conf file reflects the changes are being properly made as intended.
