• Question 284:

  You receive a HelpDesk ticket from a user that is unable to access the host server6. bigcorp. com from their workstation. The user's workstation is named ciient4.bigcorp.com .The user has issued a ping command and sends you the output:

  % ping server6.bigcorp.com ping: unknown host server6.bigcorp.com Big Corp has recently transitioned from using DNS. Big Corp now uses LDAP exclusively and has decomissioned all of their internal DNS servers. With the exception of the primary LDAP server, no client has access to a DNS server. The client4 .bigcorp.com was reconfigured to be an LDAP client, as were all other hosts in the department. A check of the contents of the /etc/inet/hosts file on client 4 .bigcorp.com reveals that it does NOT contain an entry for server6.bigcorp.com. You discover that all of the other systems in the department can access server6. bigcorp. com, even though they do NOT contain an

  /etc/inet/hosts entry for server6 . bigcorp. com.

  You run the nsiookup command on client 4 .bigcorp.com and get this:

  # nsiookup server6.bigcorp.com ;; connection timed out; no servers could be reached

  When running ldapsearch from client4 . bigcorp. com, it returns the correct IP address for server6 . big. corp. com.
