We have linux machines with RedHat 6.5 operating system.
When we try to telnet to localhost on port 8182, we get connection refused:
service iptables status
Firewall is not running
telnet localhost 8182
Connection refused
cat /etc/selinux/config
SELINUX=DISABLED
SELINUXTYPE=targeted
Any suggestion on how to find the reason that we get connection refused even if the firewall is down and selinux is disabled
when we do telnet to localhost on port 8182 , we get connection refuse
This means that there's nothing running on port 8182 on the machine. Check that the service supposed to run on that port is installed and running. (TCP/UDP 8182 is usually used for the VMware Fault Domain Manager.)
On a side note, you do not need to open ports on the firewall or disable it for connections from localhost to localhost.
If you are getting connection refused there is either no service listening on port 8182 on your loopback ip address, or there is a firewall in the way.
You can verify what processes are listing on which ip/ports using netstat:
netstat -tunlp
Where t is tcp, u is udp, n is show ip and port numbers rather than names, l is listening and p is show the process.
You can verify if there is a firewall in the way by using iptables:
iptables -nvL
