FTP will work mostly right away...if you just want to shove data around thats probably the stress free method.
If you are going with SAMBA/smbfs here's a line i use for my NAS
(i have an icon on WB which i can access whenever i want to)
C:Run >NIL: Samba:smbfs/smbfs WORKGROUP="your_group" DEVICE=SMBFB: VOLUME=your_volume_name: SERVICE=//192.168.xxx.x/your_NAS/
That works a charm given your smbfs installation is working and ready.
I went as far as creating a start script which checks for the availability and only adds the NAS after becoming available and checking for and in case adding an icon to it
If you want i can post it aswell
