From inside the box you could look at /etc/inetd.conf, but i'm not sure if you can read it without root privileges.
Most services are controlled in AIX via the System Resource Controller (SRC), try the command "lssrc -a". Again, i'm not sure if you can do that without being root.
From outside the box you could use telnet as a makeshift port sniffer:
This is my usual test if a network printer is online or not: telnet to port 515 and if the banner of some lpd comes up it works.

Does anyone know if there is a C API call to get the status of a TCP port? As opposed to running netstat and parsing the results. At the moment I have to attempt to bind() and pick up on the address in use error which isn't very elegant
Thanks

I had a doubt if any services need to be restarted if port no in /etc/services in an RHEL setup is changed. For eg, the port no of 443 for SSL may need to be changed.
I hope my query is clear whether any services need to be restarted if port no in /etc/services is changed.

Hi,
How can I list running services, corresponding package name and status on the AIX host?
On Linux (Centos), I use the below code snippet:-

portreserve
PORTRESERVE(1) TCP port reservation utility PORTRESERVE(1)NAME
portreserve - reserve ports to prevent portmap mapping them
SYNOPSIS
portreserve
DESCRIPTION
The portreserve program aims to help services with well-known ports that lie in the bindresvport range. It prevents portmap (or other
programs using bindresvport) from occupying a real service's port by occupying it itself, until the real service tells it to release the
port (generally in its init script).
It is intended that portreserve runs from an initscript of its own, and services wishing to interact with it should use portrelease.
When the portreserve daemon is started, it examines the /etc/portreserve/ directory. Each file not containing "." or "~" in its name is
considered to be a service configuration file, and must contain a service name (as listed in /etc/services) or a port number. UDP services
may be specified by appending "/udp" to the service name, and TCP services by "/tcp". Several services may be specified, one per line.
For example, /etc/portreserve/cups might contain the string "ipp" or, equivalently, "ipp/tcp" and "ipp/udp" on separate lines.
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must
first run portrelease, which instructs portreserve to release the port associated with the service.
Once all the reserved ports have been released, the daemon exits.
