[code deleted...]

Consider also that the code Alan posted (not blaming you, Alan -- I know
it wasn't yours) is extremely special-purpose, because the SocketAccessor
class tries to look as much like the C interface as possible. With a
little bit of effort, one can implement a nice abstract TCP framework in a
few days or so. My time server looks more like this:

ByTcpServer
   defaultService: [:request |
      request stream nextLongPut: TimeStamp now seconds]
   forPort: 37.
(ByTcpServer forPort: 37) resume.

How about telnet?

ByTcpServer
   defaultService: [:request | | stream |
        (stream := request stream)
            next: 6; "Discard garbage characters. They must be part of the
telnet protocol, but I'll ignore them for now."
            nextPutAll: 'Smalltalk evaluation service -- '; nextPutAll:
request version; cr;
            nextPutAll: 'WARNING: backspace is not handled!!'; cr;
            nextPutAll: 'Type "self close" to end session'; cr;
            nextPutAll: 'Smalltalk> '.
        [stream
            print: (Compiler silentEvaluate: stream nextLine for: stream); cr;
            nextPutAll: 'Smalltalk> '] repeat]
   forPort: 23.
(ByTcpServer forPort: 23) resume.

We also have an object service that we use for blasting ComposedTextViews
between images (among other thing) -- better than email!

We also have an ftpd that files out code on the fly, and an httpd that
allows browsing Smalltalk over the web. All of these servers run at the
same time in a single image.

Much of the code for this general-purpose server will be in the July issue
of The Smalltalk Report, and we hope to have it live on the web for people
to play with.
