I had the same problem... The book is wrong when telling you where to put ETC HOSTS file. it should be on TCPMAINT's 592 disk. This disk has to be accessed by whoever is doing the PING...
At least that is what they told me, and it works. -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] Behalf Of Morris, Kevin J. (RET-DAY) Sent: Monday, June 16, 2008 1:54 PM To: [email protected] Subject: zVM 5.3 and DNS We recently installed zVM 5.3 onto our test VM LPAR (production is still 5.2) and encountered a strange problem in that TCPMAINT appears to be the only user that can resolve hostnames. OPERATOR, MAINT, other systems programmer CMS userids all get "Unknown host xxxxxx". Example: --- as user: TCPMAINT --- ping vm03 Ping Level 530: Pinging host VM03 (10.196.76.30). Enter #CP EXT to interrupt. PING: Ping #1 response took 0.001 seconds. Successes so far 1. --- as user: MAINT ------ ping vm03 DTCPIN0014E Unknown host VM03 Ready(00100); T=0.01/0.01 14:43:36 ping 10.196.76.30 Ping Level 530: Pinging host 10.196.76.30. Enter #CP EXT to interrupt. PING: Ping #1 response took 0.002 seconds. Successes so far 1. ------------------------- Has anyone else encountered this issue? We use RACF, but I don't see any error messages going to RACFVM or OPERATOR, so I don't think it is RACF related. Plus, when we IPL 5.2 on the test LPAR, it uses the same RACF database and we don't have this issue. Any ideas? Thanks, Kevin Morris Reed Elsevier - Technology Services zOS Systems Engineering
