Port number to use when defining System Z - FTP connection type in the CICS Explorer

Question & Answer


Question

What value do you specify for port number when defining a System Z - FTP connection type in the IBM CICS Explorer for CICS Transaction Server for z/OS (CICS TS)?

Answer

Specify the port number through which you FTP into your LPAR. Typically this value will be 21, which is a well known port for FTP. If you use Secure FTP, the default value is 22.

If you do not use the default values, then you will need to use the port number for FTP that has been setup for your environment.

You can enter a NETSTAT PORTLIST command to see the ports that are in use. Output from this command will look like this:


MVS TCP/IP NETSTAT CS V1R12       TCPIP Name: TCPIP           20:56:12
Port# Prot User     Flags    Range       SAF Name
----- ---- ----     -----    -----       --------
7     TCP  MISCSERV DA
9     TCP  MISCSERV DA

19    TCP  MISCSERV DA


20    TCP  OMVS     D
21    TCP  FTPD1    DA
23    TCP  TN3270   D
25    TCP  SMTP     DA
80    TCP  OMVS     DA

You can also check your SYS1.TCPPARMS(PROFxx) member for the PORT statement used for FTP and SSHD.
