"Connection closed by foreign host error" in Solaris 10
Version Details
The Issue
+++++++++
I have two solaris 10 Virtual Machines created using Virtual Box. One of my applications running on Source was trying to connect to Target
Source: 192.168.0.178
Target : 192.168.0.179
Application got the following error
So, I did a telnet test from source to target. But I was getting 'Closed by foreign host' error. It seems to get connected for a second, but then I get the 'closed by foreign host' error
But , ping is working fine
And I am able to ssh from source to the target machine without any issues.
After some googling, I uncommented the following line in /etc/inetd.conf
But i don't think it has any effect in Solaris 10.
Why are you targeting port 15001? Port 15001 is not a standard port number that I am aware of. I presume you have some reason for it.
Is the port in /etc/services? Could you post the output from grep 15001 /etc/services
Is the service in /etc/inetd.conf? Using the name returned above (e.g. my-svc tcp/15001) could you post the output from grep my-svc /etc/inetd.conf
Is the server listening? On the target server, could you run netstat -na|grep 15001 and post the response. If you have lsof installed, could you post the output from lsof -i tcp:15001
Is the listener logging an error, if you know where it would?
From your telnet attempt, it would suggest that the server is listening, but doesn't respond to telnet, and why should it. It is presumably a different service.
In target, I tried to start this service ( 'manager' ) on different ports like 8000, 2000, 1532
Still the issue persists. Currently I am trying to start manager process in 1532 in target.

Thank you Sylvian .
These solaris machines are virtual machines running is my home based network.
I haven't enabled any firewall . Is there any way I could disable it ?
I tried changing the port to 2012 and restarted the service in target. Now, when I try to telnet from source the telnet command hangs. I kept trying Ctrl+C to get the prompt back, but not luck. I had to close and start another putty session.
Source: 192.168.0.178
Target : 192.168.0.179 (the server which has the port I want to check if it is open)

-- From 192.168.0.178 I am running the below telnet command
