关于使用netstat -lantup查看的SSHD 6010端口解释

关于使用netstat -lantup查看的SSHD 6010端口解释：

1.使用netstat -lantup查看当前系统开启的服务端口

tcp6       0      0 ::1:6010                :::*                    LISTEN      1663/sshd: root@pts

发现

[root@server ~]# netstat -lantup
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp         0      0  127.0.0.1:6010            0.0.0.0:*                       LISTEN            1663/sshd: root@pts

[root@server ~]#

2.经查询是/etc/ssh/sshd_config中X11Forwarding yes开启了，

3.修改/etc/ssh/sshd_config，将这个参数注释，重启sshd服务，重断开连接重新登录，6010端口就会关闭了。
