firewall rules

I‘m trying to get data (AXFR query) from master tinydns server to secondary DNS server using tcpclient as follows:
tcpclient -v a.ns.example.com 53 axfr-get example.com example.com example.com.tmp

>axfr-get: fatal: unable to parse AXFR results: protocol error

How do I fix this problem?
