- The University of Illinois Computing and Communications Services Office
- has been running a descendent of the CSNet central nameserver for several
- years now. The code has proven popular and is now running publicly at
- 40-odd sites and privately at several more. The private sites either
- don't advertise the server or restrict queries to local hosts.
-
- The original CSNet server ran on port 105/tcp. I'm not sure if 105/udp,
- also assigned to "csnet-ns" in RFC-1340 (Assigned Numbers), was ever used.
-
- The present code does not use anything like the original CSNet nameserver
- protocol. About the only part left of the original server is the database
- engine and even that has been extended. The overall intent is still much
- the same: provide a way to locate and register email addresses based on
- human information such as a person's name, their office address, etc. In
- addition it functions as an electronic white pages for traditional phone
- book type information.
-
- This leads to two questions: Is anyone still using the original CSNet
- nameserver protocol on port 105/tcp? We did not think so back in late
- 1989 and so stuck with the same port number even while the protocol
- was changed to fit our needs. Second, can 105/tcp be re-assigned to
- the new name "ph" as defined by the ph protocol paper? The protocol
- definition is available for anon-FTP from uxc.cso.uiuc.edu in
- net/qi/doc/protocol.{me,ps}.
