The goal of this article is to explain how you can scan directly on your nextcloud solution.<\/p>\n\n\n\n
In my home, I have a printer from HP that is connected to my network. One of the nice feature of this printer is to be able to scan a list of documents. You put the list of documents, scan, and voila – you have a nice PDF. It’s a very good way to archive documents!<\/p>\n\n\n\n
I have a linux based computer that is used as a nextcloud \/ owncloud data storage and backup facility – my printer scan on this computer that contains a samba share.<\/p>\n\n\n\n
Step 1: Configure nextcloud<\/strong><\/p>\n\n\n\n You need to install nextcloud on this computer. It’s not the scope of this article to explain how to do it. My nextcloud installation is running with the user www-data.<\/p>\n\n\n\n You will need to install the “groupfolder” extension and create a shared folder “Scanner”. You can sync one of your personal folder too… but I use the scanner for my all family.<\/em><\/p>\n\n\n\n Let’s get the id of the group you have just created. Go in the nextcloud folder.<\/p>\n\n\n\n You can modify files locally and run the following command to scan for changes. 1 is the id that was given just before.<\/p>\n\n\n\n You will need to know where this folder is stored. In my case it’s in “\/home\/cloud\/data\/__groupfolders\/1\/”.<\/p>\n\n\n\n Step 2: Configure samba<\/strong><\/p>\n\n\n\n Now we need to create a guest samba share. It’s not in the scope of this article to explain how to install it. As a reminder samba is a way to share folder similar to \\\\192.168.1.10\\MyDocuments.<\/p>\n\n\n\n In my \/etc\/samba\/smb.conf, I have the following configuration.<\/p>\n\n\n\n [scanner] I restart samba (\/etc\/init.d\/smbd restart) and configure my printer to scan in this folder. When I scan a document, now it should appear in \/home\/cloud\/data\/__groupfolders\/1\/.<\/p>\n\n\n\n Step 3, notify the changes to nextcloud<\/strong><\/p>\n\n\n\n I installed inotify-tools.<\/p>\n\n\n\n I’ve created a small script called monitor-scan.sh<\/strong> (You will need to configure it based on your settings).<\/p>\n\n\n\n !\/bin\/bash This script will wait for an “attrib” notification in the folder that store the configurations. It’s a way to track that a document was uploaded by the printer.<\/p>\n\n\n\n When a notification occur, we launch a command to notify nextcloud that we have changed a file. The file then will appear in your nextcloud folder!<\/p>\n\n\n\n We have an infinite loop that do that again and again. Try to run the script (sudo -u www-data .\/monitor-scan.sh) and verify what’s happening when you scan a document. It should appear in your web interface of nextcloud.<\/p>\n\n\n\n Now let’s start it when you start your computer.<\/p>\n\n\n\n Edit your cron, probably with<\/p>\n\n\n\n crontab -u www-data -e<\/p><\/blockquote>\n\n\n\n You should have the first cron that was installed with nextcloud. Add the second cron (with the correct path).<\/p>\n\n\n\n *\/5 * * * * php -f \/home\/cloud\/nextcloud\/cron.php Now restart your computer… and it everything is working you are done.<\/p>\n","protected":false},"excerpt":{"rendered":" The goal of this article is to explain how you can scan directly on your nextcloud solution.
