i suggest you check out listen(8); in particular, the -d and -t
options should help you out. you can create a directory of your
own and just specify that in the -d or -t arguements.

assuming i've created /usr/foo/bin/rc/my.services and myecho is
an executable file (script or binary) that does what you want, i
think the steps you're looking for are these:
1)	create /bin/my.services/tcp1111 - this should be either an
	executable shell script like tcp7, substituting myecho for
	cat, or you could just 'cp myecho tcp7'.
2)	start listen - 'aux/listen -d /bin/my.services'

that's it, if i understand your question correctly. i'd point
out that each of these servers are, technically, a "user-level
server process". if, for some reason, you really don't want to
use listen, you don't have to. i'd urge you to reconsider, but
look at /bin/ip/*d for examples.

alright, now i'm really confused. uh, what? i'm
not sending any font information, including any
point size. unless i'm really missing something,
the font size has got to be changed on your end.

true.  my mistake.  what you are sending is:

    Content-Type: text/plain; charset="UTF-8"
    Content-Transfer-Encoding: 8bit

and thanks to ol' microsoft here i get some random font that if i spent
three weeks looking for the params _maybe_ i could change it or break
the registry db in the process...

those dudes who did mime shoulda been shot.

as brucee was saying the other day:

    [people] don't get "simplicity".

okay, i'll bite: explain, please.

//yeah i see the 'alpha'.

than what's the problem?

they were not happy with sticking with defining a character set.
they added 'formatting' information and other garbage.

having said that, ascii is guilty of it too (control info).
but it does say 'information interchange'.

unicode's fun. try it. you'll like it.

if nothing else, i find watching who complains, or
just asks questions, an interesting experiment in
what different clients can handle, and what people
are using. much to my suprise, i'm told MS Outlook
gets this one right.

i might point out Acme mail and *edmail do, too.

what hideous font?  surely you're not

[9fans] Running a server/service??

[Ish Rattan]

I have asked this question before in a different form. I have
tried and am stuck any help will be appreciated.

I want to write a server, call it myserver (works like echo except
prepends a sequence number to the message echoed back). I have code
written based on the example given in net.html/ps document. Now the
question how do I start it? I have seen entries for echo-server
running on port 7:

1. /lib/ndb/common	(tcp=echo  port=7 etc.)
2. /rc/bin/service/tcp7
3. /net/ndb/tcp/7/*

This is ok for system started server. Does one have to go the same route
or one can run a user-level server process whan no write permission is
available on the above parts of namespace?

Further, if I want to run myecho on port 1111 so that a client can talk
to it -- what are the lists of steps to perform? I want to undestand
the process of running a server process??

Thanks in advance.
