修改ssh远程登录端口 1.修改ssh服务的配置文件:/etc/ssh/sshd_config ,将 Port 22 改为 Port 3120 保存退出. [root@localhost ~]# vi /etc/ssh/sshd_config 2.修改防火墙规则 # 打开防火墙配置文件 [root@localhost ~]# vi /etc/sysconfig/iptables # 同意3120端口,在文件里面添加下面一行,保存退出 -A INPUT -p tcp -m state --stat
把ssh默认远程连接端口修改为3333 1.编辑防火墙配置: vi /etc/sysconfig/iptables 防火墙新增端口3333,方法如下: -A INPUT -m state --state NEW -m tcp -p tcp --dport -j ACCEPT 具体是这样做: ====================================================================== # Firewall configuration written
