I'm having problems in 5.4 getting automatic ownership and mode correct on /dev/bpf2. Added this to /etc/devfs.conf: # Allow group tcpdump to use bpf* own bpf0 root:tcpdump perm bpf0 0660 own bpf1 root:tcpdump perm bpf1 0660 own bpf2 root:tcpdump perm bpf2 0660 And this to /etc/devfs.rules: [devfsrules_bpf=5] add path 'bpf*' mode 0660 group tcpdump The intent is to allow members of group "tcpdump" to use /dev/bpf2 without being root. The above creates /dev/bpf[012] as desired at boot but some time later /dev/bpf2 disappears. System has two NICs, xl0 and fxp0. At this time fxp0 is not being used. Vlan0 is configured (as a VLAN of course) on xl0, and thats where I need /dev/bpf2 for tcpdump to see what my stuff is doing. If missing, /dev/bpf2 is created automatically when tcpdump opens, but its not created with the same ownership and mode as during reboot. Suspect my problem is related to [devfsrules_bpf=5] or the fact I haven't informed the system to apply this rule to the /dev filesystem. So where is the 'i' that I've failed to dot? -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
