How to transfer media to other Core or linux PC
I have scenario with one main Core (Core1-internal ip 192.168.0.1) with dual network cards and another Core (Core2 - 192.168.0.253) I'm setting up for my new house. I'd like to transfer media from Core1 to Core2. Core2 has only one network card and gets ip from dhcp of Core1.
1. Set Internal network on Core2 to 192.168.1.0 (in contrast to internal network 192.168.0.1 of Core1) and set Firewall off temporarily
2. Add share to /etc/smb.conf on Core1 (this is probably needed only in my special case, cause have symlink
ls -l /home/public lrwxrwxrwx 1 root public 17 2006-09-16 15:25 /home/public -> /home/data/public
create mask = 0777
directory mask = 0777
path = /home/data
public = no
3. Mount samba share from Core2 :
mount.cifs //192.168.0.1/media /mnt/data -o user=xxxxx
How to get live logs (unchecked yet)
On recent releases logs are updated with some time delay. To get them more in real time :
1. 'export ImmediatelyFlushLog=1' 2. then
/usr/pluto/bin/MessageSend localhost 0 -1000 7 11
or use 22 instead of -1000 (to be just for XinePlayer)

Useful hooks for adding Ruby code to GSD device
Actually, there are following hooks where you can put your code:
1. Private Method Listing - you can put there common methods which can be used in the others hooks.
2. Process IDLE - run every couple of seconds when device is not active.
3. Process Incoming Data - receive all data which comes from the device.
4. Process Initialize - call when device is starting (not real device, Pluto device).
5. Process Receive Command For Child - when device or its child receive a command from Pluto it comes here.
6. Process Release - call when device is shutdown.
