113번 장비에서
# systemctl start firewalld
방화벽 열고

240번 장비에서
[heni@intra-consulting ~] $ nmap -sT -p 10134 192.168.0.113
을 해보니 아래와같이 뜬다.
이제까지 본 결과랑은 다른데?

Starting Nmap 5.51 ( http://nmap.org ) at 2018-01-23 09:53 KST
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn


UDP포트를 스캔해보니
[heni@intra-consulting ~]$ nmap -sU -p 10133 192.168.0.113
You requested a scan type which requires root privileges.
QUITTING!


설마?
root계정으로 확인해보니
[root@intra-consulting ~]# nmap -sT -p 10134 192.168.0.113

Starting Nmap 5.51 ( http://nmap.org ) at 2018-01-23 10:04 KST
Nmap scan report for 192.168.0.113
Host is up (0.00018s latency).
PORT      STATE    SERVICE
10134/tcp filtered unknown

어제와 같은 결과가 뜬다.

결론
nmap....root계정에서 사용해야함.
