I have installed and web application which is running on port 8080 on RHEL (centOS). I only have command line access to that machine. I have tried to access that application from my windows machine from which I am connected to server via command-line, but it is giving connection time out error.
Then I have tried to open port 8080. I have added following entry into the iptables.
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
After adding this into the iptables I have restarted it with -
/etc/init.d/iptables restart
But still I am not able to access that application from my windows machine.
Am I doing any mistake or missing something?
The following configs works on Cent OS 6 or earlier
As stated above first have to disable selinux.
Step 1 nano /etc/sysconfig/selinux
Make sure the file has this configurations
SELINUX=disabled
SELINUXTYPE=targeted
Then restart the system
Step 2
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
Step 3
sudo service iptables save
For Cent OS 7
step 1
firewall-cmd --zone=public --permanent --add-port=8080/tcp
Step 2
firewall-cmd --reload
