Thanks for the fast reply and hint. I found a simpler solution here:
http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&docTypeID=DT_KB_1_1&externalId=2009546
and here:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1016039
disable welcome page:
vim-cmd proxysvc/remove_service "/" httpsWithRedirect
and managed object brower:
vmware-vim-cmd proxysvc/remove_service "/mob" "httpsWithRedirect"
you can reenable it:
vim-cmd proxysvc/add_tcp_service "/" httpsWithRedirect localhost 8309
vmware-vim-cmd proxysvc/add_np_service "/mob" httpsWithRedirect /var/run/vmware/proxy-mob
