I'm running a small web-server on a Raspberry Pi Model B+ system running Rasbian from the NOOBS install image. I have apache2 running and a DDNS service providing a URL (from duckdns.org). I'm relatively new at this, but I know my way around linux filesystem stuff. When I dig into the access.log file, I find a bunch of GET requests for a wpad.dat file all originating from 127.0.0.1. Hundreds of these seem to pop up at a time, originating from the server for some reason?
Below is a small sample:
access.log
127.0.0.1 - - [30/Sep/2014:00:06:01 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:02 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:07 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:10 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:12 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:12 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:12 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
127.0.0.1 - - [30/Sep/2014:00:06:12 +0000] "GET /wpad.dat HTTP/1.1" 404 479 "-" "-"
There are about 2,400 of these lines in the log(s), which are only about three days old. I understand wpad.dat has something to do with proxies, but I to the best of my knowledge I never configured anything for that. I know how to set up the logs to filter out these requests, but should I be concerned that this is happening in the first place?
I searched for anyone having similar issues, but none appeared the same. Sorry if this question is redunant. Let me know if there's any more information I should provide. Thanks. :)
