| Subject: (6.14) Can I use gzip with INN? |
|---|
[this was written with the help of Michael Brouwer <michael@tar.wft.stack.urc.tue.nl>] There are three things that can be effected by using gzip: Compression of old logs, compressing batches to send out, and decompressing batches that come in. With INN 1.4 all you need to do is change two lines in config.data to something like this: COMPRESS /usr/local/bin/gzip DOTZ .gzIf you rebuild INN with these options set, all logs will be gzipped, and rnews will use gzip to decompress news. gzip will automaticly and transparently decompress UNIX Compress, SCO UNIX Compress (I'm told it's 99% compatible with UNIX Compress), Pack, and gzip. Therefore, you can now receive batches compressed with any of the above listed formats. Let's say your site is now has "a universal decompresser". It has been reported that if you hardlink gzip to be zcat, and make sure that it is the zcat that INN uses, you can get the "universal decompresser" without having to use gzip for your logs. (Though, gzip for your logs is a big win, so why make trouble for yourself?) `send-uucp' will still use compress for outgoing batches, so the sites you feed won't suddenly start getting data they don't understand. Before you can send gzipped batches, you should make sure that the sites that you feed have made the above changes so that they have the "universal decompresser" too. Edit send-uucp to use gzip instead of compress for certain hosts (see example of using compress -b12 for the host esca in send-uucp), outgoing batches will be gzipped. If you use sendbatch, you will have to edit the file so that COMPRESS is set to "gzip" and COMPFLAGS is set to "-9vc". ------------------------------ [Last Changed: $Date: 1997/07/01 01:25:41 $ $Revision: 2.21 $] [Copyright: 1997 Heiko Rupp, portions by Tom Limoncelli, Rich Salz, et al.] |
