Software :: Clients Cannot Find Network Scanner?

Feb 5, 2009

I currently have a network with an older machine, which is (usually) operated in headless mode as a data & backup server, with a fixed IP of I have two client machines, a desktop & a laptop, which use DHCP. All three computers are running Slackware-12.2, the clients with a full install & the server without any X components. I want to set the server to serve a scanner & have been following this link, which is mostly a rewrite of the man page for sane.d. I set up saned per the article, adding the saned:saned user. 'scanimage -L' works for both root & my local user on the server. I can ssh into the server as my desktop user & 'scanimage -L' works. Ditto if I ssh into the server, then 'su -' to root. I can scan either locally from the server or via ssh from the desktop machine. BUT, I cannot get the scanner recognized on the network. On the server, I have this line in /etc/sane.d/saned.conf:

Code: this line in /etc/services:


sane-port 6566/tcp #SANE network scanner daemon & this line in /etc/inetc.conf:


sane-port stream tcp nowait saned:saned /usr/sbin/saned saned

I have changed the line in /etc/sane.d/saned.conf to just "+", for testing. That didn't work either. On the clients, I have these two uncommented lines in /etc/sane.d/net.conf:


My server user is in the same groups, less vboxusers. The server is identified in /etc/hosts & I can connect to it via ssh & mount nfs shares from it. What am I (not) doing that is killing network scanning?

Ubuntu :: Canon MX320 Scanner Not Able To Get The XSane Image Scanner To Recognize Scanner?

Jul 11, 2010

I just received a Canon Pixma MX320 as a gift.

I am currently running the Ubuntu 10.04 OS

I was able to get the printer up and running by downloading the printer driver for debian linux (3.1) from the Canon site without any problems.

Unfortunately I am not having the same luck with the scanner.

I tried downloading ScanGear MP for Linux (deb) (1.3) from the same Canon site but have not yet been able to get the XSane Image Scanner to recognize this scanner driver for my Canon.

Debian Hardware :: Cannot Find The Scanner

Mar 10, 2015

Very easy to get the printer working via wifi on this printer/scanner under Wheezy. But oh the scanner! XSane doesn't see it via wifi- worked ok on USB. Problem could be with Xsane or CUPS? URL....One shows various useful tips under one roof: I can now access the scanner using xsane on the command line; but xsane cannot find the scanner when launched normally]

Hardware :: Find Scanner - Yes / Scanimage - No

Oct 25, 2010

I posted in the Ubuntu forum regarding a problem with an HP Scanjet G4010 scanner, but now I have a specific question. The scanner is reported with lsusb and recognized by sane-find-scanner, but scanimage -L does not find the scanner. My question is: What would be the cause of the scanner being reported in lsusb and sane-find-scanner but not recognized by scanimage -L?

Ubuntu :: Unable To Find The 'scanner' Drivers?

Mar 10, 2011

I have a CanonMP280 printer and Ubuntu 10.10. Mp280 is not recognized by Ubuntu 10.10. Through 'cybertechhelp' I was very lucky to get the printing drivers to install. So the printer works.

No-one seems to be able to find the 'scanner' drivers and Canon_help is useless. So I must dual-boot with Windows to be able to scan.

Although win7 is a vast improvement on vista. I would much prefer to single-boot with Ubuntu. I tried other Ubuntu and Ubuntu-Based distros, but, the printer-drivers I have, only work in Ubuntu 08.04 - 10.10

Slackware :: Sane - After Upgrade To 1.0.22 Cannot Find Scanner

Mar 24, 2011

I have a Samsung SCX-4200. It was working pretty good with sane 1.0.21. I'm using slackware current, keeping updated (almost) every day. On the Mon Feb 28 update sane was updated to sane-1.0.22-i486-1. After that update xsane (as user) cannot find my scanner. I was able to find it running sane-find-scanner as root, but scanimage -L (as root) wasn't able to find the scanner. Now I have updated to the last sane package, named sane-1.0.22-i486-2 . In the changelog I can see that this rebuild should add libusb support.

In fact, now there's no way to find the scanner. And now also sane-find-scanner (as root) is no more able to detect the scanner, also running the command as root. I've tried running sane-find-scanner -v -v and scanimage -v -v -L but I can't get no useful hints. I have checked the sane configuration files but always seems good (the row with USB IDs is not commented in the backend file, which is xerox_mfp, and the backend is listed in dll.conf).

Ubuntu :: LibUSB Not Available To Sane Find Scanner

Apr 21, 2011

I too have what looks like the same problem. I too have read all the relevant man pages and other relevant sites:

CanoScan LiDE 110 (the printer I've just bought) has "complete" support apparently.
Followed directions here: [URL]

The solution? Use windows xp in a vm.

I don't think much of that sort of solution. As a temporary work around... ok. I'm running debian lenny.

Ubuntu :: Why Can't 9.10 Find My Epson TX110 Printer/scanner?

Apr 29, 2010

I can't use my printer/scanner - it is an Epson TX110. When I try to use Image scan - I get the message; "Could not send the command to scanner. Check the scanner's status."

There is nothing wrong with the MFC apart from not working on Ubuntu 9.10. I have had it connected to another computer that ran Ubuntu 9.01 (I think that was the release used) and it ran fine but now I'm stuck -

I have drivers installed but cant get them to co-operate with me.

I don't really have a reason for this currently. I recognize all the MAC address on my DHCP client list and keep it rather well locked down.

Software :: Kerberos Clients Cannot Find Administrative Server Through DNS

Jun 27, 2010

This problem has taken me the whole Sunday and the only thing I've got left before start kicking my computer equipment is to ask you guys for help.I have a problem on my client side of Kerberos. Basically, none of my clients is able to make a connection to kadmin using DNS SRV-records. Only if I use the relevant directives in the krb5.conf files - it works.

Something is weird regarding the adm server. I mean, without [realms] stanza, the client does query the DNS properly for the KDC master - it can be tracked in the DNS logs and I mean, even logically - with no [realms] stanza - there is no other place than DNS where it can find this information. So, the actual authentication of the principal works. It's the kadmin-part that exits with the error message above. According to all manuals, books, guides I've read - this shouldn't be happening. The [libdefaults] with default_realm defined in krb5.conf in combination with proper DNS records, should be everything kerberos client needs. But apparently not.I don't remember having any problems like this before. This is the first time in several months a freshly install a KDC. I believe Kerberos packages did get updated few times since then. Could this be a bug of some kind introduced in never version of libs? I have the latest packages on centos 5.3.

Each time I connect to a Mumble server, this appears:Quote: Unable to find matching CELT codecs with other clients. You will not be able to talk to all users.

Ubuntu :: Can Not Get A Network Scanner To Work / What To Do?

Nov 8, 2010

I'm trying to get a network scanner to function. I've been following the guides here:

And I think I am just misunderstanding something.

1. The scanner is properly functioning on the server side.

2. Both, the client and the server, have the package sane-utils installed.

3. I changed /etc/default/saned on the server to RUN=yes (that was easy!)

4. Editing /etc/sane.d/saned.conf is what I think I'm getting confused on. The internal IP address of the server is and the subnet mask is The internal IP address of the client is So, what do I put there? Is correct? That didn't work!

5. Also, editing /etc/sane.d/net.conf on the client is confusing me too! What IP address should go there? Can I put the server name? What is the correct syntax?

6. I added saned to the correct group, lp. I made sure that the scanner was owned by the correct group by doing these commands:
ls -al /dev/bus/usb/XXX/XXX
The group was lp.

Just to be clear, I am not asking about connecting a usb scanner then sharing it over a LAN, that's different. This scanner plugs straight into the LAN.

OpenSUSE Network :: 11.3 NFS Server - Clients Cannot Connect

Jan 2, 2011

Upgraded two machines to 11.3 in the past 2 weeks. NFS is broken on both, in different ways. The problem I'll mention here is that the nfs server is running, but clients can't connect.

The server is running:
tinderbox:~ # /etc/init.d/nfsserver status
Checking for kernel based NFS server: idmapd running
mounted running
statd running
nfsd running

It has a valid export list:
tinderbox:~ # showmount -e
Export list for tinderbox:

The export exists:
tinderbox:~ # ls -lR /usr/local/share/
total 4
drwxrwxrwx 2 root root 4096 Jan 2 12:10 common

total 0
-rw-r--r-- 1 root root 0 Jan 2 12:10 test.txt

But attempts to mount the export are unsuccessful, both from the local machine:
tinderbox:~ # mount.nfs /mnt -v
mount.nfs: timeout set for Sun Jan 2 12:14:19 2011
mount.nfs: trying text-based options 'addr=,vers=4,clientaddr='
mount.nfs: mount(2): Connection timed out
mount.nfs: Connection timed out

...and from an OpenSUSE 11.0 machine.
moira:~ # mount.nfs /mnt/tmp/ -v
mount.nfs: timeout set for Sun Jan 2 11:52:17 2011
mount.nfs: text-based options: 'addr='
mount.nfs: Unable to connect to, errno 110 (Connection timed out)
mount.nfs: mount to NFS server 'rpcbind' failed: timed out, giving up

I've had NFS running on my local network for over a decade, and never had problems like this before.

Hardware :: Getting Canon 8800F Scanner Working / No Other Scanner Found?

Recently got a Canon Canoscan 8800F after looking it up on the SANE site and said it was completely supported for Linux.

I have downloaded the pixma drivers and have compiled the command line program, but it can't find the scanner.

lsusb returns a Canon scanner Bus 001 Device 005: ID 04a9:1901 Canon, Inc.

and sane-find-scanner returns:found USB scanner (vendor=0x04a9 [Canon], product=0x1901 [CanoScan]) at libusb:001:005

but scanimage -L (under my user login or sudo) returns only the webcam. No other scanner found.

My system is running Linux Mint 7, ia64 kernel 2.6.28-11-generic

Debian :: Sane - Share Epson Scanner Over Network

Apr 29, 2010

I have a debian server (squeezzy) amd 64, running with an epson BX-300f pluged to USB. And I want to share the scanner over my network. So let's do that, Intalled sane, sane utils, iscan, which I've downloaded from epson drivers and wich include epkowa drivers fro scanner to work..
after that I installed on my system (Ubuntu 9.10) xsane... on console I type:

root@bruno-laptop:/home/bruno# scanimage -L
*** glibc detected *** scanimage: free(): invalid pointer: 0x00be63d0 ***
WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect

device 'net:' is a Epson Stylus BX300F/TX300F/NX300/ME Office 600F flatbed scanner

I don't know why I find so much things, if i only have one scanner. Then I opened xsane and found the scanner over network. I chose the epson with epkowa drivers I try to scan something but it dont output nothing and sometimes it gives me "end of file reached". I can put whatever config files here if you want to, just ask. One time it worked fine.. but only half of an image...

OpenSUSE Hardware :: Scanner Works But Won't Network / Solve This?

Mar 19, 2010

Fresh install of openSuSE 11.2.
Laserjet 1220 multifunction device.

Successfully installed, network driver also installed, XSane shows both local and network scanner on local machine. Scans locally via both drivers.

However, networked scanner is not discovered by machines on local network, using XSane. Did a similar installation a few months ago with openSuSE 11.0, which works fine on the same client machine.

Have tried disabling firewall, but still no joy.

So, questions:

1] Is there anything I have missed?
2] Is anything known to be broken in 11.2?

Ubuntu :: Share A Scanner On Network In Lucid System?

Jun 27, 2010


Your scanner is installed properly and fully function. If you need to install your scanner first, have a look at the ScanningHowTo. To check if your scanner is connected and installed properly you can use the command "scanimage -L".
The machine we're configuring to use as the scanner server has the ip address and subnet-mask This means that this machine is on the (CIDR notation) network/subnet. code...
