I cannot connect to the server

About this task

Because Remote System Explorer accesses IBM® i servers, check for any firewalls between your local workstation and the IBM i server to make sure they are configured to allow communications to pass through. The firewall needs to pass traffic through on the ports that the client and server use; instead of blocking traffic on those ports. The IBM Toolbox for Java™ handles the communications to and from your i server, using http://www.ibm.com/systems/i/software/toolbox/faqports.html.

  1. The first thing you can do is check your TCP/IP access to the IBM i server. Open a command prompt and enter
    ping hostname
    where hostname is the name of your i server. If you can not ping your i server then you have a connectivity problem.
  2. If you can ping your server, but continue to have a problem, you can verify your IBM i connection. In the Remote Systems view, right-click one of your subsystems, such as Objects, and select Verify Connection. The dialog box verifies your connection, and notifies you if you need any PTFs. More information on verifying connections is below.
  3. Some components will need additional program temporary fixes (PTFs). To find more information about any required i server PTFs:
    1. Open the Remote System Explorer perspective (if it is not already open) by selecting Window > Open Perspective > > Other and select Remote System Explorer. The name of the current perspective is shown in the top left corner of the title bar for the Window.
    2. Create a connection to your i server by expanding New Connection > IBM i.
    3. Expand your new connection and right click on Objects.
    4. Select Verify Connection from the menu. This displays a dialog that shows which required PTFs are already installed on the system and which ones are missing.

One additional local port that should be opened is port 4300, which the STRRSESVR command uses from the workstation, to monitor "call backs" from the i server to your local workstation. See also Port information.
