"But i have one question: in the file wvdial.conf i put my password and this file must be executed and everybody can see it. How i can hide the password?"
I used to hide the password in wvdial. That was a long time ago and I think that this is the way to do it:
In /etc/wvdial.conf set Password = to a file name:
Password = /etc/wvdial.security
Set the permissions of /etc/wvdial.security to 600.
In /etc/wvdial.security you have either:
Password = mypassword
I don't remember which.
