<P>Hi Jeff,
|
|
<BR>
|
|
<P>that of course is also no good reason and it should be changed in
|
|
<BR>
|
|
the backend or sanei_pio. If I remeber right single port permissions
|
|
<BR>
|
|
can be set by fcntl so that a user process can access the releavnt ports.
|
|
<BR>
|
|
Hm, is it possible to create a separate process with SUID bit set that
|
|
<BR>
|
|
sets the port permissions so that your backend can work with user permissions?
|
|
<BR>
|
|
<P>Bye
|
|
