RedHat9:How to find what is blocking the port 1526/tcp
I'm trying to configure IDS9.40 on Ret Hat 9.
The server has opened the port 1526/tcp
nmap (nmap -sT -O linux) reports correctly that the port is open.
However, portqry (portqry.exe -n 192.168.0.101 -e 1526 -p TCP) reports that the port is closed for connection:
TCP port 1526 (turbo service): NOT LISTENING
I've dissabled the firewall on linux (/usr/sbin/setup) also added the IP address of Windows client into /etc/hosts.allow
Does anybody have any idea what I've missed out?

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
