I have PCLinuxOS installed on a machine which I run as a printer server using an Epson SX435W printer/scanner. This works fine for printing over the network and for scanning with iscan on the server. However I am unable to get the scanner working from another machine.

My problem is not actually with iscan but in getting root access on the server to make changes to files to make it work.

If I try to log-in as root I get a message that I am not allowed root log-in. I tried to sudo kwrite to edit files but didn't have sudo installed. I installed sudo and now I can run sudo and it asks for a password then says I don't have permission as I am not entered in sudoers file. I can't change the sudoers file as I don't have root access and I can't get root access because I'm not in the sudoers file - impasse!!

Any suggestions?

Mike

Not sure if you are trying a GUI login or terminal but if GUI try a terminal.

In a terminal type the following

If all else fails, you could boot from a live CD and edit sudoers manually.

OK I can use su + password then open sudoers with vim but it says you have to use visudo to edit. Did this and tried to read man sudoers but I can't work out how I edit and what the correct entry should be.

I guess I'll stick with using the server to scan and transfer the files over the network. Just means I have to log-in to the server.

Thanks,
Mike

Why not just edit the files you need to make ISCAN work as root and not bother with sudo for now.

once logged in as root you can still launch kwrite from the terminal.

Edit...
Have a look at this link on editing with visudo It's for debian but may help in your understanding.

visudo is kjst a wrapper that uses $EDITOR to edit sudoers and does some syntax checks before overwriting the original. You can do it directly with an editor but visudo is safer. As for what to add, try one of
