Xsane and wifi scanner in other vlan

Honstyxi · 2023-01-28 08:18:18

Hi to all
i've my pc in 192.168.1.0 lan
Printer/Scanner is wifi Epson-XP-2200 - ip 172.16.1.10, (it doesnt have web interface for simpli scan by web)

The scanner/printer is in 172.16.1.0 lan
From 192.168.1.10 (my pc) i can reach 172.16 subnet: printer is installed in the pc and i print correctly from my pc

In my pc i've installed Xsane and sane, sane-airprint
When i launch scanimage -L ...can't find the scanner!

i've also tried command simple-scan "smfp:net;172.16.1.10" but it doesnt find scanner: unable to connect!

Can you helm me?! i ve to config sane daemon for reach 172.16. subnet?
I haven't found any info about

thanks in advance

Welcome to the Arch Linux forums. You need to tell us more.
You mentioned VLAN in the title, but you did not elaborate in your post. Are you using VLANs? If so, they are logically separated and are not accessible by design. If you are not using VLANs, and you really have a 172.16.0.0/16 sub net and a 192.168.1.0/24 sub net, then I assume that those sub nets share the same router?

The simple solution might just be to add a second address to your NIC from the 172.16.0.0 sub net such that your PC has a toe in both sub nets.

Thanks for you answer and excuse me for my bad explanation:

in my lan i've two vlan: default vlan1 192.168.1.0/24 and vlan2 172.16.1.0/16
in vlan1 there is my pc 192.168.1.10 and in vlan2 there is 172.16.1.10 Epson printer/scanner
there is a router that route connection from vlan1 to vlan2 and a managed switch L3

my pc can correctly reach Epson for printing but Xsane software in my pc doesn't find scanner!

I hope I explained well in order to allow someone to help me debug.
Maybe I need to configure the saned daemon to allow it to find scanners on different networks than the one it's on?

Ah, I missed that fact that you can print. Is there a route back from the scanner to the PC? It might be that the printer needs to open a stream in the reverse direction; I don't know that to be true as I am not that familiar with the in workings of sane.

Did you try https://archlinux.org/packages/communit … imagescan/ ?

yes, there is a rule that allow packet from scanner to vlan1

i think is a sane config for allow a discovery scanner over other subnet...

Can you use the scanner inside the same subnet?

nmap 172.16.1.10

there is a rule that allow packet from scanner to vlan1

Where is what rule precisely? Also for UDP?

There's a http and https port…

If your device supports sane-airprint, but DNS-SD autodetection is not possible through vlan routing you can add the device manually to the sane-airscan config:
https://github.com/alexpevzner/sane-air … of-devices

But according to the manual, only AirPrint/Bonjour printing seems to be supported, no scanning: https://download.epson-europe.com/pub/d … 1553eu.pdf

The scanner does not seem to be supported by ImageScan v3, but for network access you need an additional nonfree package from the AUR. Maybe it still works even if not explicitly supported.
https://wiki.archlinux.org/title/SANE/S … ge_Scan_v3

The scanner driver epson provides for this scanner is epsonscan2: https://aur.archlinux.org/packages/epsonscan2
In the GUI you can manually add a scanner if it doesn't detect it.
Edit: For the sane module of that driver, the manual device URL would be

epsonscan2:networkscanner:esci2:network:###.###.###.###

Network access with the built-in sane driver does not seem to be not supported:
