    No accurance in IANA :
    http://www.iana.org/assignments/port-numbers
    
    http://www.snort.org/ports.html?port=6398 
    It's not in the snort port database.
    
    It's not in the trojan list :

    http://www.sys-security.com/html/papers/trojan_list.html
    
    
    So a capture of the tcp stream could be useful ;-)
