Problem: EXTRACT (Propagation) ABENDED and TCP/IP error 110 (Connection timed out) in gsserr.log
You can check by telnet command from source node to target:
telnet ip_of_target port_of_gg (ip_of_target and port_of_gg from extract configuration file).
During the telnet trying to connect, run netstat command from source server.
Expected output of telnet command: Connection timed out
Expected output of netstat command on source node: SYN_SENT
Solution: Configure fire wall to open 7809 port.
