I've arrived at that conclusion myself. I was hoping that I could use NFS - and even finally tracked down and corrected a problem in my NFS server, which hadn't been working for a long time (I had typed a period instead of a comma in /etc/exports). It doesn't look like NFS is an option, but at least I got my server going again, so it wasn't a total waste if tune. I looked for information on sane-airscan, but I couldn't find anything really meaningful, and it just didn't give a good feeling in my gut. It looks like SFTP is the way to go - if I can only get it to work. There are a few frustrating gaps in the documentation of the profile setup screen. First of all, when filling out the "host address" box the Brother web site says "type the Host Address or the IP address, and type the path to the folder. Do not type a slash symbol at the beginning of the path." Why not have a separate field for the path? If I must combine them, how do I do so? How does the system tell where the IP address ends and the path begins? Why is a leading slash prohibited? I'd think it was essential. I'd expect a standard notation like 192.168.0.5:/home/cjg/scans but it doesn't like that. I eventually found that 192.168.0.5home/cjg/scans was accepted, even though my intuition screams out that it's wrong. For that matter, 192.168.0.5/home/cjg/scans is accepted too, even though it has that leading slash that I'm not supposed to enter. This brings me to the next problem: authentication. I've selected "password" and typed in the user ID and password I use on my computer. But then we get to that "Server Public Key" entry. The web site says "Select the authentication type from the Server Public Key drop-down list." This is misleading; it seems to be not a list of types, but rather a list of public keys. So off I go to the "Server Public Key" screen under the Network tab and select "Import Server Public Key". Aha - there's "Select the server public key file", complete with a "Browse" button. Unfortunately, the file browser in my web browser (Seamonkey) is brain-damaged: it won't let me type in a filespec, and the .ssh directory is hidden. OK, copy .ssh/id_rsa.pub to my home directory and select it from there. That gets it onto the server public key list. Back to the profile setup screen, where id_rsa.pub now shows up under "Server Public Key". Click "Submit". "Would you like to test your SFTP settings?" I click Yes, it goes away for a few seconds, then comes up with "authentication error". By this time it was well past midnight, so I declared the process a dead end. Has anyone else managed to set up SFTP? In the meantime, I figured I'd fall back to sneakernet. I plugged a thumb drive into the scanner's USB port, selected "Scan to USB", dropped 40 sheets of paper into the feeder, and told it to do a double-sided scan at 300 dpi. It quickly feed the sheets through, occasionally pausing to digest, and in the end I wound up with a good-looking 80-page PDF file. Emboldened by this, I went into the advanced options and turned on "Continuous scan", then dropped in the first part of a 300-page manual. Once the sheets were scanned, the scanner asked me whether I had more; I put in the next bundle of sheets, said yes, and away it went. All was well until partway through the last set of pages - on about page 280 the scanner halted with an error message saying it had run out of space. A sheet was half-fed, the PDF file was incomplete and therefore corrupt, and a second file was created which contained garbage left over from a previously deleted file. That's not graceful - the least it could have done was closed off the file cleanly. The 2GB thumb drive was only 3% full. (Maybe the limit is internal to the scanner.) For now I'll assume a limit of 200 pages per file, and use pdfunite to put the pieces together in the computer. -- /~\ Charlie Gibbs | They don't understand Microsoft \ / | has stolen their car and parked X I'm really at ac.dekanfrus | a taxi in their driveway. / \ if you read it the right way. | -- Mayayana
