So telnet actually is working, I mean telnet localhost 25 is connecting; but telnet localhost or telnet localhost 9000 got such result: 

Trying 127.0.0.1... 
telnet: Unable to connect to remote host: Connection refused

nmap results:

$ nmap localhost

Starting Nmap 6.00 ( http://nmap.org ) at 2013-10-03 00:54 MSK
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00030s latency).

nmap on 9000 port: 

$ nmap -p 9000 localhost

So the question is how to open necessary port, Im using Ubuntu 13.04; tried to disable ufw, tried to play with iptables; nothing helped. Dunno even what to do...

I need 9000 port for hadoop; I cant access fs without opened 9000 port

hadoop
