Request:
You have a working dial-up configuration with ISDN and have set the dial-mode to "manual". Now you want "normal" users to be able to dial.

- Only "root" should be allowed to open the connection:
- SuSE Linux 6.4:
- In YaST:
-> System administration -> Security settings -> General information on system security
set the option "File permissions are set to: secure".
- or change olny the permissions for
isdnctrl
as root:
chmod 700 /sbin/isdnctrl
and change the appropriate line in the file /etc/permissions.easy
:
/sbin/isdnctrl root.root 700
- SuSE Linux 6.3 and older: Default
- Only privileged users should be allowed to open a connection ( recommended for all versions ):
- Add the user to the group "dialout":
e.g. activate the flag "Access to modem permitted" for this users in YaST "User administration".
- As user root: change the permissions for
isdnctrl
:
chown root.dialout /sbin/isdnctrl
chmod 4750 /sbin/isdnctrl
and change the appropriate line in the files /etc/permissions.easy
and /etc/permissions.secure
:
/sbin/isdnctrl root.dialout 4750
- All Users should be allowed to open a connection:
- SuSE Linux 6.4:
In YaST:
-> System administration -> Security settings -> General information on system security
set the option "File permissions are set to: easy" (default).
- SuSE Linux 6.3 and older, or file permissions "secure":
As user root: change the permissions for isdnctrl:
chmod 4755 /sbin/isdnctrl
