Re: [sane-devel] SANE needs a GUI like CUPS's 'system-config-printer' to manually add a network scanner.
Greetings, I have an HP OfficeJet Pro 6978 MFC. I have two Linux computers at home, a desktop and a laptop. Both are able to print to it, no problem. I configured the desktop with hp-setup from hplip, using the USB cable. That configures the device to use the wifi. Once configured, I disconnected the USB cable and that desktop computer is able to use the scanner, no problem. I have another laptop, which I just want to connect to the same scanner. I do not want to set the scanner up again, since it is already configured. I just want to tell Sane that there is a scanner at address 192.168.1.157. Sane fails to detect it, and I have no clue how to add it using a GUI nor a terminal for that matter. The should be a GUI feature that allows me to add a scanner the same way one can add a printer.

Nope, that is not the case. system-config-printer is only for the printer side of a MFC device. I can print to my MFC, but I cannot scan it. As a scanner, it does not exists and I have no means to add it manually to Linux. I don't understand precisely. Are you talking about HP printers or Brother MFC one? Brother provides a dedicated command-line tool to configure both printer and scanner.

In that case it's good to have workarounds to overcome the limitations. I'm not affiliated with Ubuntu either (but I do have a Launchpad account) and I no longer use any of the 'buntus. I don't let those kind of "details" get in my way when a "dumb decision" wrecks my workflow or causes me lots of extra work. If the maintainers of your preferred distribution(s) break things, it's up to them to fix them (possibly with the help of knowledgeable users) and not the upstream project. > Thanks to another user we got now Brother brscan4 based scanners working > too (by using an unconventional approach) with relevant scanning apps > (Xsane, scanimage, simple-scan, scantopdf)and as user. Oh yeah, hwdb files, yet another systemd thingy. Our sane-desc utility know how to create these files since the summer of 2013. I'm not sure if any distribution uses them but that would probably not have helped those brscan4 users anyway. > Summary of all workarounds: > > https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1728012/comments/76 Thanks for the feedback, -- Olaf Meeuwissen, LPIC-2FSF Associate Member since 2004-01-27 GnuPG key: F84A2DD9/B3C0 2F47 EA19 64F4 9F13 F43E B8A4 A88A F84A 2DD9 Support Free Softwarehttps://my.fsf.org/donate Join the Free Software Foundation https://my.fsf.org/join -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org

What I was complaining about was 192.168.2.14, not .12, which is correct. I am looking around trying to find where I saw .14. -- sane-devel mailing list: sane-devel@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/sane-devel Unsubscribe: Send mail with subject "unsubscribe your_password" to sane-devel-requ...@lists.alioth.debian.org

I had found that portion, but got frustrated with them calling "hostnames" as "IP addresses". Not the same thing. Hostname is before the IP address is resolved. You're right that host names and IP addresses are not the same thing, but the saned manual page says: The access list is a list of host names, IP addresses or IP subnets (CIDR notation) It doesn't say they are the same thing. It just says that you can use whatever combination of these three is most convenient for you. I have to go and find where I got the misunderstanding. One of the pains-in-the -neck of RHEL is that EVERYTHING is deliberately out-of-date. Man pages are often wrong. And "192.168.2.12/29" which only gives you a single IP address with its subnet mask. Using that would allow access from all eight IPv4 addresses that have the same 29 initial bits as 192.168.2.12. Please note that the CIDR notation was introduced exactly to allow addressing on arbitrary bit boundaries. See https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing From the above link: For example: 192.168.100.14/24 represents the IPv4 address 192.168.100.14 and its associated routing prefix 192.168.100.0, or equivalently, its subnet mask 255.255.255.0, which has 24 leading 1-bits. the IPv4 block 192.168.100.0/22 represents the 1024 IPv4 addresses from 192.168.100.0 to 192.168.103.255. Which was my complaint with "192.168.2.12/29" which only refers to one IP address, not all the IPs in its mask (not the block). If you wanted everyone in 29's mask (the block), it would have been written as 29's broadcast address, not a member of the mask: 192.168.100.12/29 meaning 192.168.100.12 to 15 The above line shows that you do not need the subnet mask. xxx.xxx.xxx.0/24 tells you all the IP's from xxx.xxx.xxx.1 to 255 Can I get away with 192.168.222.0/23? That would be 192.168.222 to 223. 1 to 255 Yes. Hope this helps, Yes it does! Thank you! Are you able to look at my error log over on "[sane-devel] where is my socket error?"
