Hugo, The security is usually set on /usr/sbin/pppd Check with $ ls -l /usr/sbin/pppd To enable dialout without Root permission do: $ su - root (not for Ubuntu) # chmod a+x /usr/sbin/pppd or under Ubuntu related Linuxes $ sudo chmod a+x /usr/sbin/pppd will usually enable dialout by any User. Some Linuxes do security scans periodically and reset weakspots to the more secure installation defaults.
