Re: [nslu2-linux] Re: Slug as Time Machine

One more piece of information: although I can't recall explicitly doing so, it appears a guest account already exists on the Slug. From /etc/passwd:

guest:xqnMpE/plEnFs:501:501::/home/user/guest:/dev/null

   Okay - looking through /var/log/messages, I found these entries when the Slug starts up:

Feb 25 18:39:18 (none) daemon.debug afpd[450]: Finished parsing Config File

   Then, when I try and connect over afp from my OS X client, I get these entries:

Feb 25 18:46:23 (none) daemon.info afpd[553]: ASIP session:548(5) from 192.168.0.183:64201(7)

Feb 25 18:46:33 (none) daemon.info afpd[450]: server_child[1] 554 done

   So, it looks like I'm getting permission errors when I attempt to login as guest, indicating either (1.) permissions are not setup for the TimeMachine share, or (2.) the permissions are not inclusive enough. However, I have no idea if the permissions are native to afpd, to the system, or something else entirely.

   I realize I'm pretty far down the rabbit hole on this one, but I appreciate any ideas the community might have.

   Thanks again.

   Accordig to http://netatalk.sourceforge.net/2.0/htmldocs/afpd.conf.5.html (under "Logging Options"):

"Extended logging capabilities are only available if Netatalk was built using --with-logfile. As of Netatalk 2.0, the default is --without-logfile since the logger code is partially broken and needs a complete rewrite (the -setuplog option might not work as expected). If Netatalk was built without logger support then the daemons log to syslog."

   I checked in /var/log and don't see any netatalk*.log file, so I'm assuming netatalk has been compiled without logging enabled.

   Here's where I show my lack of *nix skillz: where would I find the syslog on an unslung system?

I just tried this on my nslu2 running debian lenny

1) It does not work when using
AppleVolumes.default: /home/user "user"
and the default afpd.conf
2) It does work without authentication using
afpd.conf: "Time Capsule" -uamlist uams_guest.so
AppleVolumes.default: /mnt/directory "TimeMachine"

In case 1) I get errno -1069 in the terminal or
when using finder: Volume user could not be mounted
Under 2) I used finder and connected via
afp://ip address/TimeMachine

as guest - and there it was !

Hmm, what are the log files in your case
/var/log/syslog has some info in my case.

Otherwise it should not be too hard to compile under debian but the problem must have a simpler solution than that.
