Changi NNTP Server 1.0

Using Non-NNTP Newsreaders

Changi supports newsreaders which don't connect by NNTP, but rely on the standard newsbase storage layout. Such readers will directly access the articles on the disk and will not connect the server. Remote reading is possible through drive sharing.

However, a problem may arise because of Changi's file linking emulation. On UNIX machines, which is what most such newsreaders are designed for, the file system provides a mechanism to let more than one directory entry point to the same file. This is most useful in case of crossposts, where the same article file appears in several different newsgroup directories. To avoid storing several copies of the same article on file systems like HPFS, which don't support linked files, Changi uses a simple workaround. Articles' copies do not contain the complete contents, but a reduced set of header lines derived from the original article, which is stored only once. An added header X-Linked is put in front, which points to the location of the original article.

This somewhat incompatible behaviour can be switched off when calling Changi with option -xl.
