Need help in ICM Port Errors

Hi !I run 2 machines as a domino mailcluster. Node A and Node B. They have 2 FQ IP adresses and do their job well. Now I´m trying to configure the ICM for iNotes-Access. I exactliy did what I read in the Domino Helpfiles. The ICM is configured on Node A , I configured a port named ICMPORT, I set up the IP for the ICM on Linux as eth0:1, I did all in the notes.ini to make it possible to run the http and ICM both on port 80. But in all ways I tried to start the ICMPORT I always got THIS errormessage:

"Error on Listen function: The TCP/IP stack can´t bind an network adress to a TCP socket, please verify that …

Listener Task for port ICMPORT ist suspending for 20 seconds due to listen errors"

SO, what can I do ???

Please Help

Also make sure that you bind your hostname for the HTTP service:

In the server document, “Internet Protocols\HTTP” make sure to fill in “Host name(s)” according to DNS or local host file and then “Bind to host name”.
