Message-ID: <880602124550.014174@DOCKMASTER.ARPA>

I am looking for a suite of examples using UDP, ranging from something
simple (say an echo server) to something more complex (say TFTP). Can
someone point me to public domain, anonymous FTP-able, sources? In
particular, I am looking for examples using the Berkeley socket
interface to UDP.

We run TCP implementations on Unix systems as well as VMS, Macintosh,
MSDOS, Cray CTSS, and VM/SP. What did you want to know?

While it may be a bit late, I thought I should post a short summary of the
information I got in response to my query a few weeks back - it did generate
some discussion, after all. If you recall, the issue was how to use subnetting
on a network structure with a big backbone net and many small ones hanging
off of it. I think the below is the essence of what I found out; I also have
a pile of mail for those particularly interested.

- Unequal-sized subnets, whether or not a Good Thing, is not currently
  implemented in any generally accepted way (and thus of little interest to
  us).

- Partitioned subnets (i.e. subnets of a given net interconnected only by some
  other net) are out.

- One can have several logical subnets on the same wire (i.e. the backbone in
  our case), thus effectively increasing the address space, at the expense of
  some manual "routing" (i.e. gateways have to be explicitly told that the
  different subnets can be accessed via the same interface - hosts on such
  a wire can be "fooled" into believing that it's all one (bigger) subnet).

We will probably go for the latter method, with a long-term goal of splitting
our backbone by using dedicated routers.

Thanks to all who offered help and advice!

Two places that we use are:

OMNICOM, Inc. 115 Park Street S.E. Vienna, VA 22180 (703) 281-1135

AlphaGraphics 10215 N. 35th Ave. Phoenix, AZ 85051 (602) 863-0999

Both try to obtain up-to-date copies of the standards documents and offer document duplication services. I believe both will take phone orders on major credit cards. OMNICOM also provides seminars on ISO protocols, etc.

Message-Id: <21877@amdcad.AMD.COM> Sender: tcp-ip-request@sri-nic.arpa To: tcp-ip@sri-nic.arpa

Has anyone put together a program/shell script that converts /etc/hosts to the standard RR format as specified in the RFCs listed?

Thought I'd ask before I get a coleague to spend time reinventing it. Thanks !!
