Hi, everyone.

I tried this on Day 12: Linux Network Services, but I failed several times. Can anyone guide me on how to do this lab? Do you have additional resources for me to follow?

following are the steps you need to follow

  1. check the mentioned port is associated with any other application, if yes first change the port of that application
  2. start the apache server which is httpd
  3. add the rules in iptables before the rule of reject.

Hi @shehpar @Ashen_Ellawala

You need to ssh to Appserver 1, which could be having some issues with the said port already assigned to some other process. You need to identify the PID of that service and kill it.

Once the Port is free, you need to restart the httpd service and then Add IP Table rules

Assuming you have changed to root userm or use sudo to the below command
iptables -I INPUT -p tcp -m tcp --dport <Port Number> -j ACCEPT

Check if the rules are properly added to /etc/sysconfig/iptables file.

Exit of App Server and test it with curl
