Hallo,

 

warum zeigt nmap andere Ergebnisse von verschiedenen Servern aus?

 

Ein Test von zu Hause aus:

 

Arktur:~ # nmap 79.246.83.43

Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-31 08:47 CEST

Nmap scan report for p4FF6532B.dip0.t-ipconnect.de (79.246.83.43)

Host is up (0.081s latency).

Not shown: 995 closed ports

 

PORT    STATE    SERVICE

22/tcp  filtered ssh

80/tcp  filtered http

135/tcp filtered msrpc

139/tcp filtered netbios-ssn

445/tcp filtered microsoft-ds

 

Nmap done: 1 IP address (1 host up) scanned in 51.74 seconds

 

Von der betroffenen Schule aber aus:

 

Arktur:~ # nmap 79.246.83.43

 

Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-31 08:44 CEST

Nmap scan report for p4FF6532B.dip0.t-ipconnect.de (79.246.83.43)

Host is up (0.083s latency).

Not shown: 988 closed ports

 

PORT      STATE    SERVICE

22/tcp    filtered ssh

80/tcp    filtered http

83/tcp    filtered mit-ml-dev

543/tcp   filtered klogin

1075/tcp  filtered unknown

1864/tcp  filtered paradym-31

3404/tcp  filtered unknown

3995/tcp  filtered unknown

4446/tcp  filtered unknown

5500/tcp  filtered hotline

8333/tcp  filtered unknown

10082/tcp filtered amandaidx

 

Nmap done: 1 IP address (1 host up) scanned in 42.75 seconds

 

Auch ein Test für eine andere Schule von zwei verschiedenen Servern aus, zeigte
Unterschiede.

Von DBG aus:

Arktur:~ # nmap 79.210.127.50

 

Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-31 09:03 CEST

Nmap scan report for p4FD27F32.dip0.t-ipconnect.de (79.210.127.50)

Host is up (0.15s latency).

Not shown: 998 closed ports

PORT   STATE SERVICE

21/tcp open  ftp

22/tcp open  ssh

 

Aber von zu Hause aus:

 

 

Arktur:~ # nmap 79.210.127.50

 

Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-31 09:02 CEST

Nmap scan report for p4FD27F32.dip0.t-ipconnect.de (79.210.127.50)

Host is up (0.100s latency).

Not shown: 995 closed ports

PORT    STATE    SERVICE

21/tcp  open     ftp

22/tcp  open     ssh

135/tcp filtered msrpc

139/tcp filtered netbios-ssn

445/tcp filtered microsoft-ds

 

Viele Grüße

Mirek
