Direction issues

This piping does not appear to work, here is my command line:

ra -S 127.0.0.1 -w - | rasqlinsert -r - ip -w mysql://username:password@192.168.1.1/db_name/table_name <mysql://username:password@192.168.1.1/db_name/table_name> -s autoid stime saddr daddr -s -record -d -m none

I get the rasqlinsert[PID]: Timestamp started message, however no data is inserted into the database. The schema is created, however.

If I run just: ra -S 127.0.0.1 -w - I can see all the binary output to the terminal.
