I posted this before on the security basics, but haven't recieved a response, and it worries me a bit, so I'm sending this to a few other groups in hopes that someone will have an idea about it. --- Fairly recently I noticed my ftp client wouldn't list files in certain directories on my server anymore - so I ssh'd in (it's dedicated), and did a ls -aFl on the files, hoping to see what the problem was - here are a few of the results: -rw-r--r-- 1 larry 503 371 2005-02-25 08:36 head.php -rw-r--r-- 1 larry 48 873 2005-09-09 03:23 foot.php I never set the group ids to 503 or 48, so I checked just to make sure - and no groups with those ids even exist. Is there an exploit/tool that causes this, and should I be worried? I checked the processes running, and everything seems to be OK - same with any processes connecting to the internet.
