You can test if IguanaX is running on a port using either curl or wget. These are command line tools which can be used to pull down a file from a webserver.
Most systems will have either curl or wget - you’ll need to see what the default tool is for your system. They can both operate with similar syntax:
wget http://localhost:7654/ curl http://localhost:7654/
These are both command line clients for web browsers - they are useful when you are on a server which doesn’t have a built in web browser like many Linux servers.
If these fail to connect then it’s indicative of a problem with Iguana listening on port its web interface. Things to check here are whether you can run Iguana at the command line like this:
[ec2-user@ ~]$ ./iguana Running service as command line application. (ctrl+C to exit) Instance: /home/ec2-user/.iNTERFACEWARE/IguanaX/Yj75m3hhEnpLVgp65kNgUN/ Listening on http://localhost:7654/ Normal production mode. Initializing the log system... Log system initialization completed. Control+C to exit.
If you can run it this way then it might be worth checking if SELinux is active.
