Error: Environment validation filed for environment "LINUXTARGET" host "192.168.175.140". Cause: Validation of user environment failed.

#DemoEnvironment

Usually the cause of this issue with landshark is the DNS that is being fed to your systems. (nfs attempts reverse dns)

Click the upper right menu on the Delphix engine and go to the server setup page

login with sysadmin/sysadmin

modify the network settings and remove the dns server.

reboot the delphix engine. 

Try again.

I also have tried this commands in the LINUXTARGET:

Hey Sergei, that is what I would suspect on the linuxtarget. Your situation is different than Amandeep's. In his case, I want him to run those commands on the Linuxsource. 

Thank you, Adam! It's work! Great!

Supreme.
