Misc Freebsd Notes

Random things from the recent past, for the record.

The setup I described some time ago for taking regular snapshots of the file system corrupted my file system in obnoxious ways.  This is appears to be a known problem for some other folks.  Doing repeated fsck didn’t resolve the problem; deleting all files from the snapshots and then doing the fscks did.  I’ve turned it off; which is a bummer.

I have this “HP Media Center PC”, a “HP Pavillion a1125c”, inherited from an elderly friend who was clearing out assorted junk.  Rumor is it was the victum of a power surge via the Ethernet; and the Ethernet certainly doesn’t work.  I stuck a cheap Ethernet card in it.  I’ve no idea who to blame for the resulting “elm kernel: dc0: watchdog timeout” messages in /var/log/messages.
I setup Music Player Daemon on a machine, which is very nice.  I then setup Firefly so the same collection can be played from the Macs around the house.  It’s nice too.  Avahi provides the mDNS support to make that visible to iTunes.  Avahi complains (a lot) about “avahi-daemon[1224]: No slot available for legacy unicast reflection, dropping query packet.”  I haven’t puzzled out how to make it happy.

I setup netatalk so as to get an Apple File Protocol deamon (afpd) that would let the family add things to the Music Library.  The deamon, afpd, complains when launched “main: atp_open: Can’t assign requested address,” this message went away when I disabled the old Apple datagram protocol support, via -noddp.  Now it only emits that error message occationally, I have no idea why.  It is also complaining about “bad function 4C”, but that appears to be a known problem with Leopard’s AFP implementation having as yet undocumented additions.

This machine has sound hardware who’s vendor, it appears, hasn’t let the open source community have at it.  So I had to install something called Open Sound System (sic).  It took me a while to figure out that i needed to use ossmix to turn up the default volume: e.g. “ossmix connector.green.green 80:80” to get the stereo mix to 80% on both left and right channels of the green colored connector on the back of the machine.
I came into a Seagate FreeAgent Pro 750Gig usb drive; which I’ve been hoping to use with Bacula.  Sadly it doesn’t play nice with the HP a1125c; the BIOS hangs on boot if the usb drive is plugged in.  Otherwise it works fine.
I also came into a Apple Time Capsule, which is very nice.  It has a USB connector, so I put the 750Gig USB drive on it.  That requires reformating it to something The time capsule wants to mount.  The time capsule makes it’s drives visible via AFP, and SMB.  There doesn’t appear to be a way to mount AFP file systems on FreeBSD, netatalk can provide them but not mount them.

Freebsd has mount_smbfs built in so I went down that path.  The auto mounter (amd) has a not unusual feature where it takes file names like /net//foo/bar and squeezes out the duplicate slashes.  In spite of clear instructions in the documentation I was unable to get amd to mount my SMB file path, since they start with two slashs.  So instead I have amd mount the drive via a script, and that script names the drive.  The man page for amd.conf was key to seeing how to get enough logging to see what wasn’t working.

The 750gig drive is enthusiastic about putting it’s self to sleep.  That might be why I’m getting assorted time outs at this point.  But then again it might because the time capsule is busy doing other things.  I’m also getting “kernel: smb_iod_recvall: drop resp with mid 4858” errors in my logs.

This machine’s logs are getting to be a mess.  That’s a dangerous situation since it leads to ignoring other errors.  For example looking I see a few of these “arplookup failed: host is not on local network.”  Hm.    I may need to dust off some old code I’ve got for log file analysis and monitoring.

If I was a better person I’d add lots and lots of links to this posting.
