Ubuntu :: Finding A TWAIN Tool To Operate A Scanner Using The TWAIN Protocol Over USB
Dec 20, 2010
I am looking for a NATIVE Linux tool (e.g. does NOT require WINE) to operate a scanner using the TWAIN protocol over USB. I found a package called "twain" but it appears to not be a package. The following message is produced by attempting to install it:
Code:
E: Package 'twain' has no installation candidate
The following information is produced about it by the "aptitude show twain" command:
Code:
No current or candidate version found for twain
Package: twain
State: not a real package
I'm looking for a real package, of course.

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.

I am trying to search a tool for testing multicast. Currently, 'yum search multicast' yields nothing. I saw mcsender and mctest in google but they seem not to be supported in CentOS. Do you know any tool that can test multicast?

I deleted files on my linux drive that I shouldn't have. What is a good tool to use to recover these files that will:
Recover the various file types (txt, php etc)
Recover it as the original files names
TestDisk and PhotoRec almost do the trick, but the original filenames are not restored.

My collection contains some MP3s which have some glitches like
displaying the wrong duration on loading
minor jumps
suddenly ending despite the duration claims another minute remaining
noise
I'm looking for a tool that can detect as many of these glitches as possible and fix those that can be fixed (obviously e.g. noise can not simply be eliminated in most cases).

I just installed ubuntu 10.10 on my HP G70-460US laptop, the ethernet connection works but my wifi card cant be detected..I dont know if the the wifi state being "off" (there is a button to turn it on and off) has anything to do with ubuntu not being able to pick up on it..but even before i had no problem getting ubuntu to find the proprietary drivers.

I'm looking for a tool that can directly convert mp3 file to a swf file. Tried ffmprg - 'ffmpeg -i master.mp3 -ar 22050 -ab 32 -f swf -y -vn new.swf', output is as follows:
Output #0, swf, to 'new.swf':
Stream #0.0: Audio: 0x0000, 22050 Hz, stereo, 0 kb/s
Stream mapping:
Stream #0.0 -> #0.0
Unsupported codec for output stream #0.0
I found a way to perform this task using ffmpeg to convert the mp3 file to a wav file, and converting the wav into a swf file using swftools (wav2swf), although this is not a good option because the output swf file size is very big - for a 12mb input 320kbps stereo mp3 file, the swf file is 25mb. Also downloaded a free direct mp3 to swf conversion software, which had an output swf file - with the same 12mb mp3 file - of ~400kb.
The requirements I have from the tool are:
1. Can be ran from the shell.
2. Direct conversion, or an indirect one that will produce a small output swf file.
3. Suport for multiple file conversion is a plus.

I was able to get my Epson Stylus NX510 printer up and running (after much issue), but I can't get the scanner working. I'm on a laptop, and the printer/scanner is wifi enabled and broadcasts with its own IP address. I can print with no problem, but xsane and simple scan don't recognize the scanner. I'm running Ubuntu 10.04 Lucid Lynx.

How to get this scanner to work with Ubuntu 10.10
It's connected and printer is working through the scanner.But i can't get the system to recognise the scanner.
I'm all new to Ubuntu, and i thought it was easy and terminal is a totally new thing to me.
Is there a workaround to get this scanner to work through graphical interface install, or is terminal wisdom needed...

I've installed XSane Image Scanner. When I first opened it, it searched for my scanner and didn't give any error messages, and it had my scanner model in the heading of the scan window. But when I hit the scan button, it gave me saying, "Failed to start scanner: error during device I/O.I closed everything, and opened XSane again. This time it said there was no scanner available. The scanner is plugged into the USB port and uses that for both power and data. It's a Canoscan Model N650U.

After downloading and installing iscan and run it i see this message:
Could not send command to scanner. Check scanner's status.
After command sane-find-scanner:
And this message is result of scanimage command:
No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).

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

I've used Jaunty since it came out have been quite happy with it. However, it is no longer supported and I can't access updates. When 9.10 came along, I tried to install it but found my system would randomly freeze. In fact, it randomly freezes with 10.04 as well. I tried Linux Mint's equivalent to Ubuntu's 9.10 and 10.04 and have the same problem. I've visited discussion boards and see that this is a huge problem for many Ubuntu users --- but I've never found a solution that works.
I assume the problem is in the kernel and am interested in seeing if 10.04 will run on that kernel version. My questions are these:
a) Is my conclusion that the source of my problem is the kernel a reasonable conclusion to reach?
b) If the conclusion is reasonable, is it possible to run 10.04 using the same kernel that 9.04 came in?
c) If the answer to C is, "Yes," then is there a tutorial that will walk me through how to install kernels?

I recently downloaded a copy of Kubuntu from the official website...when i finished downloading it and tried to run it inside windows, my virus scanner immediately picked up several malware inside temp files in my computer called win32 antivirus. I attempted to install kubuntu on my computer on a partition (i've previously done this on other computers no issues) but it had multiple partitions. Instead i tried to do a clean install of kubuntu then attempt to install vista again then. However it is now telling me my files are corrupted and will only operate Kubuntu. This is not what i want, i wanted to operate both on partitions as i haven't completely figured out how to use kubuntu?

I am unable to run Veracrypt on Debian 8.3 64 bit. Yet I have applied the installation procedure.
I downloaded the 1.16-veracrypt-setup.tar.bz2 archive and I unpacked in a directory veracrypt I created in my home.
I get 4 files: veracrypt-1.16-console-setup-x64; veracrypt-1.16-console-setup-x86; veracrypt-1.16-setup-gui-x64; veracrypt-1.16-setup-gui-x86
I keep 2 that match my 64-bit architecture, ie: 1.16 veracrypt-console-setup-and-x64-veracrypt 1.16-setup-gui-x64.
I log in as root in the terminal. I slip the veracrypt-1.16-setup-gui-x64 file. Validate the installation choices by default. After completing the installation, I see the icon Veracrypt and when I click on the Veracrypt application does not start.

I'm wondering if it's possible to operate a Web Server 'without' registering a domain name, using an IP address alone.I currently have Apache & Tomcat running on one of my workstations. I am currently using these servers as development sandboxes; and I have P2P Search Engine 'YaCy' running under Apache, which is accessible from the outside to the entire P2P network.
Since my Apache server is accessible from the outside, I was thinking that I might setup one of my other workstations as a server with just my 'external' IP address & port number as a way of reaching my site, i.e. http:// 255.183.47.201:8090/. I can't see any reason why this wouldn't be possible. I seem to remember several of my former companies doing this on their corporate Intranets. Also, I wouldn't be locked into registering a domain name every year; and I wouldn't have to worry about any content restrictions. If my intended audience knows where to find me; I can't see any reason why this wouldn't work. And, I don't see why my site couldn't be indexed by search-engines. The only caveat I can think of is making sure I have enough bandwidth from my ISP to support the anticipated traffic.If this will work, I assume I can setup a regular website, an online store, podcast, or provide any other type of tradional web-service this way.

I was experimenting with Emacs and Xemacs - trying to chose between them. Finally I've re-installed Xemacs and find that keyboard in Xemacs don't operate.
I'm using openSuSE 11.3
Emacs 23.1.1
Xemacs 21.59....
Perhaps I should uninstall Emacs?
