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. --Jack Fitch (Fitch@dockmaster.arpa) include <std_disclaims.h> ---------------------------------------------------------------------- Received: from uxc.cso.uiuc.edu by SRI-NIC.ARPA with TCP; Thu, 2 Jun 88 09:13:15 PDT Received: by uxc.cso.uiuc.edu (5.51/9.7) id AA23522; Thu, 2 Jun 88 10:28:59 CDT Date: Thu, 2 Jun 88 10:28:59 CDT From: kline@uxc.cso.uiuc.edu (Charley Kline) Message-Id: <8806021528.AA23522@uxc.cso.uiuc.edu> To: tcp-ip@sri-nic.arpa Subject: Re: non-*NIX implementations We run TCP implementations on Unix systems as well as VMS, Macintosh, MSDOS, Cray CTSS, and VM/SP.

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! ---Per Hedeland ---------------------------------------------------------------------- Received: from ucbvax.Berkeley.EDU by SRI-NIC.ARPA with TCP; Thu, 2 Jun 88 10:28:56 PDT Received: by ucbvax.Berkeley.EDU (5.59/1.28) id AA18222; Thu, 2 Jun 88 10:04:56 PDT Received: from USENET by ucbvax.Berkeley.EDU with netnews for tcp-ip@sri-nic.arpa (tcp-ip@sri-nic.arpa) (contact usenet@ucbvax.Berkeley.EDU if you have questions) Date: 1 Jun 88 19:00:48 GMT From: amdahl!pyramid!leadsv!excelan!chuck@ames.arc.nasa.gov (Chuck Kollars) Organization: Excelan Inc., San Jose, CA Subject: Re: Third TCP-IP Book?
