i want stop LFD service, beacuse when website have many connect form ip address, lfd will block this ip address. this is resolutionStill.... why should one want to disable LFD? There are so many options to enable or disable if something is disturbing.
I would never disable a part of that firewall.
what have occur when you should that turn off Syn_flood ?You probably have Syn_flood active. You could just punt synflood = 0 and leave portflood empty and start lfd again.
Normally however, this should not be a problem so I hope people are not doing SlowLoris attacks at your system.
It will start again on server start/reboot (you should disable it from autostart), and of course on csf update/upgrade.
# Limit the number of IP's kept in the /etc/csf/csf.deny file

# Care should be taken when increasing this value on servers with low memory
# resources or hard limits (such as Virtuozzo/OpenVZ) as too many rules (in the
# thousands) can sometimes cause network slowdown

# Enable SYN Flood Protection. This option configures iptables to offer some
# protection from tcp SYN packet DOS attempts. You should set the RATE so that
# false-positives are kept to a minimum otherwise visitors may see connection
# issues (check /var/log/messages for *SYNFLOOD Blocked*). See the iptables
# man page for the correct --limit rate syntax
#
# Note: This option should ONLY be enabled if you know you are under a SYN
# flood attack as it will slow down all new connections from any IP address to
# the server if triggered
