not sure where you got the software, so I don’t know how it was configured and how it was set up, but I’d guess that any user name (admin, for example) with a password of “mt-daapd” might work.
If not, check the config file. Use any user name and the password specified as the “admin_pw” in the config file (Typically /etc/mt-daapd/mt-daapd.conf, or /opt/etc/mt-daapd/mt-daapd.conf).
From Infrant. Firefly svn-1676 with some svn-1696 fixes is included with the latest firmware.
This may be of use to you Ron.
Compiling natively on the ReadyNAS is slow. How about a cross-compiler?
You can grab a tarball of a cross-compiler to compile using an x86 system from here. It includes gcc, g++, and development headers, for use on Linux-based systems. Extract the tarball from your root directory to ensure things are placed in the correct path.
