There are several. * Any graphical tool that will work with BSD lpr will work with PPR if you make a fake /etc/printcap and set up the PPR UPRINT wrapper programs. * If you have Perl/TK installed, you can run the PPR program "printdesk". I consider it experimental and it is rather basic, but it works. * PPR 1.40b1 contains an alpha level WWW interface. Look in www/README.txt for instructions for editing /etc/services and /etc/inetd.conf. This will get the WWW interface working in read-only mode. To get the WWW interface working in read-write mode, you need a web browser that supports Digest authentication (which for the moment means Internet Explorer or Amaya), Perl's MD5 module, and a /etc/ppr/htpasswd file. For now, the htpasswd file can be created with the htdigest program from the Apache web server. Use a realm name of "munch munch munch". One big problem with the WWW interface is that it tries to use advanced web browser features such as style sheets, Javascript, and digest authentication. All current browsers have severe bugs and limitations in this area. Mozilla renders the pages with the greatest correctness, but doesn't yet support digest authentication. IE supports digest authentication and has only a few rendering errors. Netscape through version 4.7 renders poorly and doesn't support Digest Authentication. Amaya supports digest authentication but renders poorly and doesn't support Javascript. I am pinning my hopes on Mozilla, but it doesn't support Digest authentication yet (though supposedly it will by milestone 14). Mostly, the WWW interface falls back gracefully (even with text mode browsers such as Lynx and W3m), but I really don't want to allow Basic authentication. ================================================================ David Chappell David.Chappell@Mail.Trincoll.Edu Computing Center PostMaster@Mail.Trincoll.Edu Trinity College (860) 297-2114 Hartford, Connecticut 06106
