Hi Dusty,<br>
<br>
That should work as long as user dclark belongs to the group users.<br>
Check with 'id'<br>

Pardon for the noob question, but I have Etherlab 1.5.2 set up on a<br>
Fedora 19 system, and have a strange issue with reserving a master instance.<br>
<br>
To start with, I *should* have read/write permission on the<br>
device:[dclark@bukhansan Debug_ecat]$ ls -l /dev/EtherCAT0<br>
crw-rw-r--. 1 root users 249, 0 Jan 1 13:33 /dev/EtherCAT0<br>
<br>
But when I wrote the simplest possible application to just request and<br>
then release the master to check I had all the build and link options<br>
set correctly, I got the following error:<br>
<br>
[dclark@bukhansan Debug_ecat]$ ./TestServo<br>
Failed to open /dev/EtherCAT0: Permission denied<br>
FATAL: couldn't request a master instance.<br>
<br>
Running it as root:<br>
[root@bukhansan Debug_ecat]# ./TestServo<br>
Master instance created ok<br>
Releasing master...done!<br>
<br>
Any ideas why this would be? Thanks in advance!<br>
