Below is a script that posts a test message via a public newserver and
provides a randomly generated title and Message-ID. It uses the "rpost"
command, which is included in the "suck" package to post the message.

I'd like to add a "suck" command to the script to read the message back
from the server, using the specified Message-ID, and to display that
message. I guess I'll figure out how to do it eventually, but the "suck"
command seems to be far more complex than "rpost" and it requires config
files. There's no easy way to do this that I'm missing, is there?


#!/bin/bash
newsserver=aioe.cjb.net
id=$(od -xvAn -N8 < /dev/urandom | tr -cd 0-9a-f)
rpost $newsserver <<%end
From: scriptpost <script(a)post.invalid>
Newsgroups: alt.test
Subject: TEST-$id
Organization: scriptpost
Message-ID: <$id(a)post.invalid>

test $id
%end

Sure there is.

With 'article' you get the post with the requested Message-ID.
Now write a little expect script and you're done.

Thanks for the reply. I've installed tcp and expect, but I find the
expect manpage to be hard reading. I've managed to get it to display a
post, although I don't really know how to separate the server messages
from the post. The "interact" tells it to display everything, and it
does exit without user intervention, but I'm sure there's a neater way.

#!/usr/bin/expect -f
spawn telnet aioe.cjb.net 119
sleep 1
send "article <0123456789abcdef(a)foo.invalid>\r"
sleep 1
send "quit\r"
interact


I might look into trying something similar to the above, but using bash
pipes rather than with expect.

I also figured how to use "suck" to get a message by its Message-ID. This
script reads a message from a public newsserver and saves it as the file
"feedback.txt". (It also uses 3 temporary files in the local dir.)

#!/bin/bash
echo "alt.test -1 0" >sucknewsrc
echo "<0123456789abcdef(a)foo.invalid>" >suckothermsgs
suck aioe.cjb.net >feedback.txt
rm -f sucknewsrc suck.newrc suckothermsgs

Expect is a little hard going, but learning it is absolutely essential
if you want to consider yourself a Unix scripting guy. The book
"Exploring Expect" (by Don Libes, author of Expect) is absolutely
essential.

The script below is to get latest posts from a newsgroup via nntp.
It uses just bash.
If you post a message and run this script after few seconds I think
the probability of your message be the last is great.
In anyway the value of the var "REPLY" has more info than checked in the
script and, message ID, can be present.
Perhaps you would prefer get a list instead, sending with the script:
se "XOVER $[$LP-5]-$LP" 224
And selecting via the "ID" as said in your post.
Try play a bit with this; add echo $REPLY >&2 to see server's answer.
I don't have examples with SSL, only this one for plain text.
I'm not sure if this is what you wanted.

------------------
#!/bin/bash

S=194.177.96.26 # nntp.aioe.org
P=119
G=comp.unix.shell

e(){ exec 3<&-;exit 1;}

se(){ # send $1 expect $2
[ -n "$1" ]&&printf "$1\r\n" >&3
read<&3;[ "${REPLY%% *}" = "$2" ]||e
}

exec 3<>/dev/tcp/$S/$P||e

se '' 200

se "MODE READER" 200

se "GROUP $G" 211
LP=${REPLY% *};LP=${LP##* } # LP = latest post

[ -f /tmp/$G ]&&LL=$[`cat /tmp/$G`+1]||LL=$LP # LL = latest local
echo -e "LL=$LL\nLP=$LP" >&2

while [ $LP -ge $LL ];do
se "ARTICLE $LL" 220
[ -e /tmp/$G.$LL ]||while read -t 3;do [ "$REPLY" = .$'\r' ]&&break
echo "$REPLY"
#echo "${REPLY%?}" # \x0d cut
done <&3 >/tmp/$G.$LL
echo /tmp/$G.$LL >&2
echo $LL >/tmp/$G
LL=$[$LL+1]
done
e
