Petr/Linux,
If you are relying on port 524 to get SAP information for NCPFS over TCPIP, you may want to track this since it appears Novell will be patching this port to close a security flaw. I added the tracking URL so you can review what changes they are proposing. I think what they are proposing as an immediate patch may break NCPFS -- you will need to check.

Novell NetWare discloses system information
Novell's NetWare operating system contains a flaw that allows system information to be leaked via TCP port 524 in pure IP configurations. When NetWare is used in a mix Microsoft environment, the Novell operating system leaks data via Service Advertising Protocol (SAP). Other third-party applications compound the problem as well. A hacker can use the data to gain knowledge on the inner workings of the affected system. It is recommended that port 524 be blocked to prevent any leaks. For more information on SAP: http://support.novell.com/cgi-bin/search/search.pl?database_name=kb&type=HTM L&docid=%03%21F221133%3a973867389%3a%20%28%2010050864%20%29%20%20%07%01%00&b yte_count=71624
