Error is 138: Connection timed out

NoMachine Version – 4.2.26

I am using NoMachine to connect from my windows 7 machine to Unix (CentOS). I successfully installed NoMachine on my CentOS. I then installed NoMachine on my windows, but I am not able to connect from my windows to my unix machine using NoMachine.

I always get the following error –

Could not connect to the server.
Error is 138: Connection timed out

Please note, I can SSH from my windows machine to the unix machine. I tried VNC from my windows to my unix and that works perfectly. I also confirmed that unix machine doesn’t have any firewall.

Please assure that you set correct host name or IP address instead of ‘UNIX IP’.

For example:

10.0.0.1

hostname

hostname.domain.com

Hi Reza… I using correct host name or IP address… UNIX IP is a placeholder with which I have masked the actual IP address…

 

I am using ifconfig to get the ip of the unix machine

Manu Sinha,

Can you verify that you can connect from Windows machine to Linux port 4000?

Thank you.
