CSF csf firewall auto starts after stop ?

yes with CSF Firewall http://centminmod.com/csf_firewall.html, csfstop or service csf stop it will auto restart

what are you trying to do ? disable CSF ? I don't advise it as CSF protects your server

Code:

csf -h
csf: v7.03 (generic)
csf(1)                                                                  csf(1)
