I'm cutting and pasting a message that originated on the mailman-users mailing list. I think this message is fairly self-explanatory. Can other NNTP experts look this over and see if it makes sense? I'll apply it if there are no objections. Note: the bare except is bothersome.

Were you running the mailman gateway on the same machine as the news server? (Or on another machine that is an NNTP peer of the news server?) Python's standard nntplib assumes that when it connects it will default to (NNRP) reader mode. If the connection ends up in NNTP/news feed mode, many commands, including "GROUP" will not be recognized. A quick hack is to add this to your nntplib.py: diff -u nntplib.py.dist nntplib.py --- nntplib.py.dist Tue Apr 28 17:43:35 1998 +++ nntplib.py Tue Jun 23 22:06:00 1998 @@ -71,6 +71,10 @@ self.file = self.sock.makefile('rb') self.debugging = 0 self.welcome = self.getresp() + try: + self.welcome = self.shortcmd('mode reader') + except: + pass if user: resp = self.shortcmd('authinfo user '+user) if resp[:3] == '381': This makes nntplib use 'mode reader' for all connections. As Harald Meland pointed out, this should probably be controlled by adding another optional argument to nntplib.NNTP(), but if you only use the library with mailman or in other "client" applications this will suffice. Jim P.S. You could also do the 'mode reader' stanza in GatewayManager, but then you also need to repeat the 'authinfo' code there if your news server needs authentication, since that must follow the 'mode reader' command. -- Jim Tittsler, Tokyo
