How to Tell What Version of Ubuntu You Are Running
Try the following:
cat /etc/lsb-release
cat /etc/issue
uname -a
lsb_release -d -s -c
sb-release is a better option for ubuntu, but /etc/issue works across most linux varieties. Uname will print information about the kernel version and is not the same as the version of the OS.
cat /etc/lsb-release
cat /etc/issue
uname -a
lsb_release -d -s -c
sb-release is a better option for ubuntu, but /etc/issue works across most linux varieties. Uname will print information about the kernel version and is not the same as the version of the OS.
Installing Canon MP210 on Ubuntu 10.10 Linux
How to use Canon MP210 on Ubuntu 8.04 (Linux printer drivers setup tutorial)
(It also applies to earlier version of Ubuntu 8+.)
Step1: Get the drivers.
You will need 4 driver packages:
* cnijfilter-common_2.80-1_i386.deb
* cnijfilter-mp210series_2.80-1_i386.deb
* scangearmp-common_1.10-1_i386.deb
* scangearmp-mp210series_1.10-1_i386.deb
Get them from here:
http://support-au.canon.com.au/EN/search?v%3aproject=ABS-EN&binning-state=model%3d%3dPIXMA%20MP210%0Amenu%3d%3dDownload%0Aos%3d%3dLinux&
Step 2: Install the drivers
Earlier version will follow below steps:
prompt%> sudo dpkg -i cnijfilter-common_2.80-1_i386.deb cnijfilter-mp210series_2.80-1_i386.deb
prompt%> sudo dpkg -i scangearmp-common_1.10-1_i386.deb scangearmp-mp210series_1.10-1_i386.deb
With 10.10 version or close:
Go to places (GUI mode) and locate the printer files (cnijfilter-common_2.80-1_i386.deb, cnijfilter-mp210series_2.80-1_i386.debin) Download folder and double click each files listed in step 1 to install. Same goes to scanner.
Step3: Add the printer (if not already added)
* System->Administration->Printing
* Remove MP210_series
* Add new printer
** Device URI hal:///org/freedesktop/Hal/devices/usb_device_4a9_1721_505BD0_if1_printer_noserial
Or do it via CUPS:
http://localhost:631/printers/
If you just need the printer, you're done!
Step4: Install Scanner
Locate the scanner files (scangearmp-common_1.10-1_i386.deb, scangearmp-mp210series_1.10-1_i386.deb) in Download folder and double click the files listed in step 1 to install.
Test by going to Application->Graphics and Simple Scan and you're done!
For old versions of Ubuntu, try below steps:
Step1: Download drivers for scanner, Extract & Build
http://internap.dl.sourceforge.net/sourceforge/mp610linux/mp150-0.14.2u.tar.bz2
prompt%> tar jxvf mp150-0.14.2u.tar.bz2
prompt%> cd mp150-0.14.2u
prompt%> make
prompt%> sudo make install
Step 2: Setup XSane
prompt%> sudo mv /usr/lib/sane/libsane-pixma.so.1.0.19 /usr/lib/sane/libsane-
pixma.so.1.0.19.old
prompt%> sudo cp libsane-pixma.so /usr/lib/sane/libsane-pixma.so.1.0.19
prompt%> sudo apt-get install xsane
Step3: Run XSane
Click Applications->Graphics->XSane Image Scanner and scan away.
Connect to 2 networks from one machine
Scenario
We want to use the Notebook built-in wireless NIC to connect to another Wireless Access
Point and also use our PCMCIA Adapter at the same time.
What we did
We want to use the Notebook built-in wireless NIC to connect to another Wireless Access
Point and also use our PCMCIA Adapter at the same time.
What we did
- Look for best TELSAT signal.
- Position notebook on the roof to act as an antenna and access point. Mount it on a high platform with clear line of sight.
- Use an Access Point with dead wireless function to act as a switch.
- Run a cat5 cable to a workstation in the house.
- Configure notebook network adapters. This is important.
How to configure?
1. In Control Panel, double-click Network Connections.
2. Right-click a network interfaces, and then click Properties.
3. Click Internet Protocol (TCP/IP), and then click Properties.
4. On the General tab, click Advanced.
5. To specify the Metrics, on the IP Settings tab click to clear the Automatic metric check box, and then enter the Metric that you want in the Interface Metric field.
How to track an Application's version number
Most applications and drivers today will check online and update you about their latest version, but we were curious to work out alternatives.
There are different methods but we prefer by Google.com. The quick method is go to www.google.com and do a search on the [Aplication Name] + [Wiki].
For e.g. we did a google search on the term "Internet Explorer Wiki " and it resulted in the url: http://en.wikipedia.org/wiki/Internet_Explorer
In Wikipedia, they listed it's history we found easily on the application page content tree as shown below:
Source: Wikipedia
Also you do not only find the version number, but some detail history and other useful information about a Software.
example:
Internet Explorer 7 was released at the same time as Firefox 2.0, and overtook Firefox 1.x by November 2006, at roughly 9% market share.[84] Firefox 2.0 had overtaken 1.x by January 2007,[85] but IE7 did not surpass IE6 until December 2007.[86] By January 2008, their respective version market share stood at 43% IE7, 32% IE6, 16% FF2, 4% Safari 3 and both FF1.x and IE5 versions at less than half a percent.[8 - Wikipedia
We came across VersionTracker which was created by Kurt Christenson in 1995 as an Apple-only site but eventually expanded to include software related to the Microsoft Windows platform, but it does not convince us because users will need to download and install the application before running it. It's time consuming!.
VersionTracker Wiki
It competes against driver/program update sniffers DriverAgent.com, RadarSync, PC Pitstop, UpdateStar, driverguide.com, drivershq.com, SUMo, and to some degree with Download.com, Softpedia, Tucows, and other file download sites, as well as MacUpdate for Macintosh software updates.- Wikipedia
So more information are collected, like similar applications and ways of keeping track of an Application version number.
