How to edit "/etc/udev/rules.d/40-basic-permissions.rules" file
Hi,
Just dual boot my Acer Aspire 5551 laptop with Ubuntu 8.10.
Have encountered some problem when trying to get by Brother MFC-260C to perform scanning. I've managed to get it to print. From the Brother web site, it was mentioned that I would need to edit the 40-basic-permissions.rules file and change "0664" to "0666". However, the text editor does not allow me to save the file. Any advise.
Also, I also encounter problem accessing a particular web site : www.ura.gov.sg
Not sure if i have missed out add-on to my firefox browser. Pls kindly advise.
When you browse to the directory where that file is, don't just open the directory by double-clicking on it. Instead, right-click on the directory (rules.d) and choose "open as root". Then open the file in a text editor and it will run as root and you can save your changes.

Well, this was a difficult one to track down, but I was sure I had read something like this recently, but it took me an age to track down the thread.
There's nothing wrong with your firefox, there's something wrong with their firewall.
At first I couldn't load the link you posted, but after giving the command
Code:
sysctl -w net.ipv4.tcp_window_scaling=0
(and you'll need to be root to do this) the site loaded fine.
To become root on an ubuntu system, in a terminal, issue the command
Code:
sudo -i
and give your login password when asked. Then give the comand as above. Please check your spelling / copying very carefully before you press <RETURN>
While I'm here, to edit that file for your printer, you need to give the following commands in a terminal:
Become root (as above). Notice how your terminal prompt has changed.
Back up the original file:
Edit the file.
Save the changes with "WriteOut" which is <CTRL><o> and then "Exit" which is <CTRL><x>
You'll need to restart udev so the changes are noticed:
Code:
/etc/init.d/udev restart
Close the terminal.
Plug your printer in and see if you can configure it.
sudo nano "file" OR use sudo vi "file", except don't write the ".
In nano, to save and exit, do Control + X, then you will be asked if you want to save y(yes) or n(no), then what to save the file as (just hit enter to keep the same name) and then your done
Its me again. After accessing the site (www.ura.gov.sg) on several different occasion, I realise that I need to key in the command / code (sysctl -w net.ipv4.tcp_window_scaling=0) every time I re-boot/power up my computer. Is there a way to set this as default?
There is also another web site that I recently encounter problem accessing : www.myhomepage.singtel.com/
The code (sysctl -w net.ipv4.tcp_window_scaling=0) did not help. Any advise on what is missing?
