Yesterday my vServer was shut down by my provider cause of some unusual load. They told me there were multiple processes running with the name dtdfs. I also see in the log that there was some some high network traffic. I now changed all passwords and restarted the server. I also tried to find a program named "dtdfs", but without any success. I also unsuccessfully grep'd the logs for that name.
I didn't have any process logging applications manually installed (it's Debian system). It isn't a highly important server (just a development server hosting some git repos), but I'd like to learn from that and find out what happened. Where should I start? What about that dtdfs process? Is there a way afterwards to get more info about that process?
