When I newly installed the Zend Studio 12.5, it required the start of ssh for connection to the Iseries IFS directory. I started it using strtcpsvr *sshd. All was working well. However when I do a netstat on the iseres, I realized that there were strange IP address (eg 222.186.30.xxx from China) appearing with ssh connection. This happens when I was the only one using the Zend studio and I am locally connected to the Iseries. Is this a hack? The IP address can keep changing and even use different user like QSECOFR, QSRV and even my own id. Only when I ended the sshd, it disappeared. It also happened when I am not using the Zend Studio. Zend Studio requires the sshd connection and I need to start it in order for it to work. So how can I secure the connection.
