NAME NNML::Server - a minimal NNTP server SYNOPSIS perl -MNNML::Server -e server perl -MNNML::Server -e unspool DESCRIPTION NNML::Server server implements a minimal NNTP server. It is (hope-) fully conformant to rfc977. In addition the commands `XOVER' and `AUTHINFO' are implemented. Supported commands: ARTICLE, AUTHINFO, BODY, GROUP, HEAD, HELP, IHAVE, LAST, LIST, MODE, NEWGROUPS, NEWNEWS, NEXT, POST, QUIT, SLAVE, STAT XOVER, XHDR, LIST NEWSGROUPS ng-spec The main reason for writing this was to synchronize my mail directories across different hosts. The Mail directories are MH-Style with a F<.overview> file in each folder and an F file in the base directory. These are maintained by the B B backend B. To get started, you can generate/update this files using the B program. Upon C and C commands this files will also be updated. To start from scratch use: touch /tmp/active; perl -MNNML::Server -e 'server(base => "/tmp", port => 3000)' To export your mh-Mail use: perl overview -base ~/Mail perl -MNNML::Server -e 'server(base => "$ENV{HOME}/Mail", port => 3000)' The command POST and IHAVE honour the `Newsgroups' header if not overwritten by the `X-Nnml-Groups' header. Articles will contain an appropriate `X-Nnml-Groups' header when retrieved by message-id. When the client submits the `SLAVE' command, all forther post requests are spooled in `$Config-'spool> (usually ~/Mail/NNML.spool) for performance reasons. You can process the spooled articles by submitting the `XUNSPOOL' command or by calling perl -MNNML::Server -e unspool Rejected articles will be saven in `$Config-'bad> (usually ~/Mail/NNML.bad) AUTHORIZATION To enable access restrictions use: perl -MNNML::Auth -e "NNML::Auth::add_user($ENV{LOGANME}, 'passwd', \ 'read', 'write', 'admin')" If *base*/passwd exists, three levels of authorization are recognized: admin Users with permission admin may shut down the server using `SHUT'. Also these users may create new groups simply by posting to them. Permission admin is also required for the `XUNSPOOL' command. write Users with permission write may use the POST and IHAVE commands. read All other commands require the read permission. FEATURES Version 1.06 implements the `MODE GZIP' command. After submiting this commands, all articles, heads and bodies will be piped through `gzip -cf | mimencode'. The server will recognize post requeste using the same pipe automatically. This will speed up nnmirror if the line is sufficiant slow. BUGS The server handles multiple connections in a single thread. So a hung `POST' or `IHAVE' would block all connections. Therfore a post request is interrupted if the server could not read any bytes for 30 seconds. The Client is notified by message 441. If the client continues to send the article, it is interpreted by the command loop. SEE ALSO The overview(1) and nnmirror(1) manpages. AUTHOR Ulrich Pfeifer
