Eeek. OK, is everything else in this relatively recent copy
of kerberos/src/prototypes/services.append properly assigned,
aside from the reassignment of the KDC?
Actually.... no, some things are still not properly assigned. Klogin and
kshell have been assigned.
klogin 543/tcp # Kerberos authenticated rlogin
kshell 544/tcp cmd # and remote shell
Kerberos has been moved to port 88, although people will have to be
listening on port 750 for some time to come, and assume that many
servers won't be converted to listen to port 88 for some time.
kerberos 750/udp kdc # Kerberos authentication--udp
kerberos 750/tcp kdc # Kerberos authentication--tcp
Kerberos_master has not be reserved, but it is only really need for
intra-site transaction, since it's used by the kpasswd and kadmin
programs. The same goes for krb_prop, which is only used between the
Kerberos master and its slaves. These port numbers *have* been assigned
for other services, so if we request official assignments for these
services, we'll have to move them.
kerberos_master 751/udp # Kerberos authentication
kerberos_master 751/tcp # Kerberos authentication
krb_prop 754/tcp # Kerberos slave propagation
passwd_server and userreg_server aren't used by any Kerberos programs
that I am aware of, so they shouldn't be a problem. The knetd port is
used, but the use of knetd has been deprecated, so getting a port for it
may not be that important.
passwd_server 752/udp # Kerberos passwd server
userreg_server 753/udp # Kerberos userreg server
knetd 2053/tcp # Kerberos de-multiplexor
These programs also haven't been assigned proper ports; we should
probably do some thing about these. These ports have been used yet, so
if we just request them to be assigned, we should hopefully be able to
get them.
eklogin 2105/tcp # Kerberos encrypted rlogin
kpop 1109/tcp # Pop with Kerberos
erlogin 888/tcp # Login and environment passing
Also, I've seen port 751 marked as "hesupd". Is that an old usage?
Yes, I'm pretty sure that's an old usage.
