How can someone limit/prevent fork bomb attacks on your system. I
recently tried one on myself after modifying kern.maxprocperuid (thinking
that should prevent it), and got my machine up to a load of over 150
before I killed it.
The simple code used was:
#include <unistd.h>
main(void) {
while(1) {
fork();
}
}
The above effectively freezing my system. :\
Anyone got any ideas?
Nick
