It is very easy to crash a system simply by viewing a large file with
editor such as pico. It will eat up all the resources and do some
unpredictible things. In my case I viewed a 100mb file as it was reading
it, it filled up all the swap space which is 48mb. It killed most of the
processes including sendmail, sshd, X, syslog. Does anyone have any idea
how can i protect myself against that kind of DoS? My configuration:
P100, 48mb ram, 48mb swap running on kernel 2.2.2.
