Netstat maps TCP/UDP portnumbers to names from /etc/services.

blackjack       1025/tcp   #network blackjack
blackjack       1025/udp   #network blackjack

What you got here is just a TCP connection from emporium port 1025 to
one of the netbios ports 137-139 on bugs.

Try "netstat -n" instead. The -n flag prevents the name mapping.
