2, about the CentOS default iptables firewall rule icmp-host-prohibited, if after installation found that the Shadowsocks has started, the local client can not connect, please check the iptables is like the following rule:

REJECT All--0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
To run the command:

/etc/init.d/iptables status
can be viewed. If you have this rule, the 8989 ports you add need to be changed manually and placed on the previous line of this rule. Edit the/etc/sysconfig/iptables file to:

-A input-p tcp-m state--state new-m TCP--dport 8989-j ACCEPT
Put in:

-A input-j REJECT--reject-with icmp-host-prohibited
The front. The final effect is as follows:

-A input-p tcp-m state--state new-m TCP--dport 8989-j ACCEPT
-A input-j REJECT--reject-with icmp-host-prohibited
When you are finished editing, restart the iptables firewall. Command:/etc/init.d/iptables restart
