I installed vncserver on my redhat, i installed same setup as i used on my last server where it worked.

But now after start vncserver and trying to connect it says "Connection refused"
I tried to check if port is open from external computer and it says its Closed.

I tried service iptables stop
and it still refused. Then i did iptables status and it shown some iptables things, so not sure if it was really stopped. so i added this rule to iptables: iptables -I INPUT -p tcp --dport 1 -j ACCEPT
my port is 1 of vnc.

but still refused. So i want to ask how to open that port? Or what to check?

the log file shows this:

can you post a output of you`re firewall ?

and post a output from this command:

iptables -vnL
Chain INPUT (policy ACCEPT 369 packets, 21993 bytes)
pkts bytes target prot opt in out source destination
4 240 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:1

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

Chain OUTPUT (policy ACCEPT 205 packets, 17621 bytes)
pkts bytes target prot opt in out source destination

ps -aux | grep vnc

Anyway, you`re Chain INPUT default policy is ACCEPT. So you don`t need that rule anymore. But you can try connectiong to that vnc-server on ports 5900 and 5901, to see if the vnc-server changed the port.

You can also try a quick capture with wirethask (graphical), or tshark (console) to see if some traffic is commeing.
Hope you don`t have a gateway in front of the machine, that blocks all, or redirects via this macine you`re useing vnc-server (just saying).

thx, for solve this. Not sure why not at port 1 not, but at port 5901 it connected

You configure the VNC server with display# not port#. Default VNC ports start at 5900, and since you won't be able to share display 0 (your console) the first normally used vnc port ends up being 5901.

You'll probably never use TCP port 1. http://en.wikipedia.org/wiki/List_of...P_port_numbers
