Jan 19 will be my Apache's one year birthday. In that time I've learned much about running a webserver on Linux. One thing I've seen many times over are GET's for /sumthin/. I don't GET it? Why /sumthin/ and not just /? Is this a way to grab banners, 404's?
Does anyone ever put something in /sumthin/?
I wanted to see what would happen if I honored requests for some of the winserver exploits. One example is I created the text file /scripts/nsiislog.dll. The text in the file is actually a record of all GET /scripts/nsiislog.dll requests. Once a week I grep | cat >> to this file. I learned that most tools (worms) scanning for this file limit the bytes to 12960-13068. I deduce that those who accepted the entire file were scanning manually with a user enabled keyboard. So what harm can there be in setting an index.html inside /sumthin/? ;-) I get far fewer requests for /sumthin/ than anything else I currently play with. I would like to explore the ramifications of utilizing this particularly regular request. I just wanted to see if there was sumthin to it before I create the index and special links. Thanks, farmer6re9
I was curious myself, so I did a little google.ca/linux and lo and behold:
"This looks to be a banner grabbing attempt on your webservers. Alot of scanners/worms will do this in an attempt to find out what type of web server you are running and compare it against a list of vulnerable servers for some particular exploit. The `"/sumthin" is placed within the GET command to trigger a 404 error, which in turn reveals valuable information about your server back the requestor. If the information returned by your server is useful to the scanner/worm you may see other exploits in the near future targeted towards your box."
