Re: pollrecvd & running scripts for every incoming fax...



well, i'm kind-of relying on the auto-indexer on the archive to help out
any fellow travellers ;-)

so here goes...

the goal was to get autodelivery of PDF image-layer files for incoming
faxes.

the key script that gets run for every incoming fax is etc/faxrcvd,
which gets run every time a fax comes in, so this needed modification
(what i ended up with is included below...i make no claims for elegance,
but it works...feel free to hack and/or add to the distribution or
contrib directory)...

--

note that i've used the tiff2ps utility from tifflib (located at
http://kubax9.kub.nl:2080/Decomate-1.0/tiff-v3.4-tar.gz), rather than
fax2ps included with hylafax, as it seems to generate higher-quality,
though fatter, PostScript, and used ps2pdf from GhostScript 5.50. Also
needed is mimencode, which comes as standard with RH 5.1, on which I'm
running...this is to base64-convert the resulting PDF file for mail
delivery...

--

anyway, here's the code...there are probably numerous security race
risks in my use of tmp/ files, so if anyone has a better idea, please
let me know...

--

(i've also changed the Sender name to fit our potenital use of it here,
so you'll need to change that)

cheers
