Re: LNXADMIN as IDENTITY
Hi Tito, the reason is, that this machine also serves as terminal server. In the cookbook, it is also used to show the different setups of RHEL and SLES for LNXADMIN, but the main reason is to run the IUCV terminal server.

Re: LNXADMIN as IDENTITY
Tito, Why not 4 LNXADMIN USERS or 1 relocating if needed... As Berthold mentioned, the Linux terminal server needs one Linux system per z/VM. If you also use these servers as LDAP or DNS servers, you may want one to be primary and others secondary/tertiary. A couple of other solutions that fit this model well are global file system servers and zoom. -Mike M On Fri, Jul 10, 2015 at 10:37 AM, Alan Altmark alan_altm...@us.ibm.com wrote: On Friday, 07/10/2015 at 10:26 EDT, Tito Garrido titogarr...@gmail.com wrote: hmmm So If I have to install/clone linux 4 times, keep it synced... why not 4 LNXADMIN USERS or 1 relocating if needed?
