Of course its relevant. The perms that you set allow *only* the root user to read /usr/local/bin/cdrecord, and no one else. I'll say it once again, you can't execute a file that you can't read. Since your normal user(s) is a member of the xcdwrite group, the perms for the group are key to fixing this. At the minimum you need: ----r-s--- 1 root xcdwrite > >>>I had to do a 'chmod +s' myself.

Fine, then do members of your xcdwrite group have rwx access to the burner device? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Lonni J Friedman [EMAIL PROTECTED] Linux Step-by-step & TyGeMo http://netllama.ipfox.com _______________________________________________ Linux-users mailing list - http://linux-sxs.org/mailman/listinfo/linux-users Subscribe/Unsubscribe info, Archives,and Digests are located at the above URL.
