[SOLVED]Open Port

UCS - Univention Corporate Server
#1

Hi, I’ve to open 10050 for Zabbix-agent.

I’ve esecute:
root@ucs-8023:/etc/security/packetfilter.d# ucr set security/packetfilter/zabbix/tcp/10050/172.16.6.75=ACCEPT
then:
root@ucs-8023:/etc/security/packetfilter.d# nmap 127.0.0.1 -p 10050

Starting Nmap 6.00 ( nmap.org ) at 2016-11-09 16:33 CET
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00013s latency).
PORT STATE SERVICE
10050/tcp open unknown

Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds

But from 172.16.6.55:
root@IbmCdLM:~# nmap 172.16.6.75 -p 10050

Starting Nmap 6.00 ( nmap.org ) at 2016-11-09 10:52 CET
Nmap scan report for 172.16.6.75
Host is up (0.00038s latency).
PORT STATE SERVICE
10050/tcp filtered unknown
MAC Address: 00:25:B3:DE:80:3E (Hewlett-Packard Company)

Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds

Why 10050/tcp filtered?
Why 172.16.6.75 does’t see ucsserver 10050 opened?

Hello,

scanning localhost is not useful. Scanning from the other machine is correct.

The UCRV was set correctly, just restart the firewall afterwards:

invoke-rc.d univention-firewall restart

Thank you

Now works fine

I solved this problem using the terminal:

ucr set security/packetfilter/tcp/10050/all=ACCEPT
