好的,我试试看,这个地址里面还提到了一个有趣的东西哦:
Protect against Fork Bombs
Fork bombs are programs that keep creating child processes until system resources are all used. They actually aren't remote exploits because they require a local user to execute the bomb; however, users may be tricked into running a fork bomb. For example, the following example may look innocent, but running it on an unprotected system may take the whole system down:Do not run the above code on an unprotected system!
The above shell script will actually keep forking at an exponential rate until system resources are exhausted.
To protect a system against such attacks, there is a file for limiting the number of processes per user. It is /etc/security/limits.conf. Add the following two lines to it:
@users soft nproc 100
@users hard nproc 150 |
