Hi Archie, I've another, probably unrelated problem that has surfaced with mpd-netgraph in the last couple of months. The work-around is simple, which is why it's taken me so long to get around to raising the issue. I start mpd-netgraph at boot time, to create a VPN link to my office, with a script /usr/local/etc/rc.d/mpd. That used to work fine, and I haven't changed my mpd configuration at all in the mean time. For the last couple of months, though, this has resulted in no ng0 node, and a log that looks like: Feb 5 21:41:46 gurney mpd: mpd: pid 240, version 3.6 (root@gurney.reilly.home 18:28 19-Jan-2002) Feb 5 21:41:46 gurney mpd: [vpn] can't create socket node: Exec format error Feb 5 21:41:46 gurney mpd: mpd: local IP address for PPTP is xxx.xxx.xxx.xxx Feb 5 21:41:46 gurney mpd: [vpn] using interface Feb 5 21:41:46 gurney mpd: [vpn] IFACE: Open event Feb 5 21:41:46 gurney mpd: [vpn] IPCP: Open event Feb 5 21:41:46 gurney mpd: [vpn] IPCP: state change Initial --> Starting Feb 5 21:41:46 gurney mpd: [vpn] IPCP: LayerStart Feb 5 21:41:46 gurney mpd: [vpn] bundle: OPEN event in state CLOSED Feb 5 21:41:46 gurney mpd: [vpn] opening link "vpn"...

It seems to be a race or dependancy problem, because the "fix" is to just wait for a couple of seconds after stopping mpd, then start it again, and then it works fine. After doing the manual stop/start sequence, the kernel mutters something like: Jan 30 09:29:03 gurney /kernel: bpf: ng0 attached Hints?
