The companion registration port for AIX NIM — how a client adds itself to an existing NIM environment.
IANA registers 1059 as nimreg, the registration half of IBM AIX's Network Installation Management pair. Where 1058 carries ongoing master/client service traffic, 1059 is used when a client registers itself into an existing NIM environment: the client obtains a socket via rcmd() and connects to the master on this port. It travels with 1058 in every NIM firewall list IBM publishes, so in practice the two are open or closed together. Finding 1059 alone is unusual and worth explaining before you accept it.
Do not expose
Self-registration into an OS-provisioning system, over rcmd-based trust — management network only.
