Example:

• sudo tee -a /etc/security/limits.conf << "EOF"
• @dos hard nproc 30
• @dos soft nproc 20
• EOF

• sudo tee -a /etc/pam.d/sudo << "EOF"
• session required pam_limits.so
• EOF

• sudo groupadd dos
• sudo useradd dos -s /bin/bash -g dos -m -k /dev/null dos

• sudo -u dos -i tee -a .profile << "EOF"
• export PATH="$HOME/bin:$PATH"
• export LD_LIBRARY_PATH="$HOME/lib:$LD_LIBRARY_PATH"
• export LIBRARY_PATH="$HOME/lib:$LIBRARY_PATH"
• export CPATH="$HOME/include:$CPATH"
• EOF

• git pull origin master
• autoreconf -i

• CFLAGS='-Ofast -ffast-math -funsafe-loop-optimizations -g0 -fomit-frame-pointer -pipe'
• ./configure --prefix=/home/dos
• make

• sudo -u dos make -j1 install

• sudo -u dos -i forkbomb
