Hi Martin,

The port numbers assignments are managed by IANA (Internet Assigned
Numbers Authority). You could find the updated list of well-known,
registered and private ports at:
ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers

Looking at this file you will find the assignments and contact points
for ports 1496, 1526, 5632. The other ports (such 1054 or 2149) do not
seem assigned (but that does not mean they are not used, unfortunately
some software are sloopy and use any available -or not so available-
port for their specific needs without bothering to request for an
assignment).

liberty-lm      1496/tcp    liberty-lm
liberty-lm      1496/udp    liberty-lm

Best regards,
