r.php doesn't exist.

This server is running Ubuntu 14.04 in a LAMP setup.

I have never seen this sort of attack before, should i be concerned or securing my system in any way for them?

Looks like someone is scanning your website on different ports and looking for a specific file (r.php) which could be a backdoor or something similar. As the file does not exist it throws errors (which is good)... I see this kind of log entries from time to time as well.

Stick to these answers on how to secure LAMP in general: Tips for Securing a LAMP Server
