1.添加端口

vim /etc/ssh/sshd_config

将#Port 22的注释去掉并且换行加入Port 443

如果是不是增加，而是修改端口的话，建议先保留22端口，等新端口可以登录再去掉。

443其实是https使用的端口，3128是squid使用的端口。建议使用大端口，比如10000~65535以上。

重启SSH服务 /etc/init.d/sshd restart
或者
Centos：service sshd restart
Debian：service ssh restart

2.防火墙开启443端口
vi /etc/sysconfig/iptables

加入-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

或者

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
service iptables save

重启防火墙 /etc/init.d/iptables restart

#ClientAliveInterval 60
#ClientAliveCountMax 3
