Hi:
I hope to get some help.If somebody has met the same problem as me?
Although gatord has already started on target board, streamline on host PC could not connect to gatord.The gatord version is updated.Target board also could 'ping' to host PC.
On pandaboard:
root@arm:/gator# ps ax | grep gatord
864 ttyO2 S< 0:00 ./gatord
987 ttyO2 S+ 0:00 grep --color=auto gatord
root@arm:/gator# netstat -pln

Why gatord did not listen to tcp but tcp6? Is there any problem?
I make another embedded system for pandaboard.The communication between gatord and streamline turns out to be ok.And gatord listens to tcp.
