NMT:Samba
Easy. Once Telnet access is enabled
Edit /etc/samba/lib/smb.conf and add a section
[USB_DRIVE_A] path = /opt/sybhttpd/localhost.drives/USB_DRIVE_A-1 read only = No guest only = Yes guest ok = Yes
I did this by simply inserting 'echo' before each line and '>> smb.conf' at the end of each line.
Stop and start the samba server to see the effect.
