Initially the client side gave me an error : 'authentication failed'. The FAQ suggests running the following initially to allow access: xpaset -p ds9 -acl clienthost + on the server host. Thereafter it worked well! Thanks for this tip... It works. Initially the client side gave me an error : ‘authentication failed’. The FAQ suggests running the following initially to allow access:

On the machine you're running ds9 (call it the "server"), configure it as per <a href="http://hea-www.harvard.edu/RD/ds9/faq.html#XPA" rel="nofollow">the FAQ</a>. Then, on the machine with the FITS file, you should be able to send the file by running: <blockquote> $ xpaset -i 'server_ip:port' ds9 fits < filename.fits </blockquote> That should transport the FITS data over the network, and then use the local DS9 to display it, so it'll be nice and fast. That said... I've not actually had much success trying to get this to work for myself. DS9 seems choosy about what network interfaces to listen on, and there will probably be all sorts of nasty issues with firewalls etc. Has anybody actually made this work reliably?
