I have found that our network and support desk guys sometimes put in the ip address instead of the MF's canonical name in the tn3270 profiles. Either way you need to make sure that if the MF address is natted that the dns reflects the new ip address.
-----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Steve Grimes Sent: Friday, March 21, 2008 10:02 AM To: IBM-MAIN@bama.ua.edu Subject: Changing the MF IP Address Hello, I'm going to a meeting next week where I will advocate moving our MF behind the firewall, which means changing its IP address. The advance discussion has turned up an argument that this could (would) break a lot of stuff. I suspect that argument is based on FUDSI. But, I'm not the one in the systems group either. Here's what I do know: --The MF is not an FTP server. We cannot ftp to the MF. We have never been able to. So, there's nothing in this area to break. (We can initiate FTP's in jobs on the MF.) --We aren't running SMTP on the MF, much to my chagrin. --Our 3270 terminal emulators (of which I have personally set up scores for various people over the years) all reference the MF by (one of) its domain names, never the IP. I think this is true for the hundreds that are out there accessing our on-line CICS applications & TSO/ISPF. --Our MF environment is a single machine with 2 LPARS (plus a test LPAR) in a "ring" mode with GRS (whatever that means.) Question for the list: What should we be checking or looking for relative moving our MF behind a firewall and changing its IP address? Thanks!
