In Host C: perform telnet localhost 3333 display: SSH-1.99-OPENSSH_3.9P1 says SECURECRT has successfully done port forwarding for you.
Or use the Netstat-ltn |grep 3333 command to view the listening port
-------------------------------------------------------------------------2. External Network D host SECURECRT settings are as follows
