Mark, Did you GRANT this z/OS?
Ray ________________________________ From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Mark Pace Sent: Monday, January 26, 2009 9:33 AM To: [email protected] Subject: Layer 2 to Layer 3 I have a Linux guest that I use as a DNS cache server for my z/VM, z/OS, and other linux guests. Friday I migrated from z/VM 5.2 to z/VM 5.4 and changed the vswitch from layer 3 to layer 2. Since this change my z/OS can no longer use the linux guest as a DNS server any DNS query (NSLOOKUP) returns: EZB3040E *** Can't find server name for address 199.44.xxx.xx: No response from server I can ping the z/OS address from the Linux guest, and I can ping the Linux guest from z/OS, so I know that the connectivity is not messed up. Another z/VM in a different LPAR using layer 3 vswitch can use the linux DNS server. It too uses the same OSA CHPID with different addresses dedicated to it's LPAR. I might add that this same Linux guests is also an FTP server. The z/OS system can connect to the FTP server either. Hardware: z9 z/OS 1.9 and z/VM 5.4 use the same OSA CHPID, just different address dedicated to different LPARs. -- Mark Pace Mainline Information Systems 1700 Summit Lake Drive Tallahassee, FL. 32317 ________________________________ NOTICE: This e-mail is intended solely for the use of the individual to whom it is addressed and may contain information that is privileged, confidential or otherwise exempt from disclosure.
