hosts.equiv (or .rhosts)

The /etc/hosts.equiv or .rhosts files, and its NIS equivalent, contain the names of remote hosts that are trusted on or equivalent to the local host. Equivalent hosts are given access to the local machine using rcp, remsh, and rlogin commands without a password. All client machines that perform DCM transfers must be equivalent hosts on the DCM destination machines.

Each host entry in the /etc/hosts. equiv file has a syntax like the following example:

hostname

hostname.domain_name.com

hostname.other_domain_name.com

If you are running NIS, update the NIS master hosts.equiv map. If you are not running NIS, you must edit the /etc/hosts.equiv file on every engine, client, and build machine.

Also, ensure that ccm_root is a trusted user on the database server, from each engine machine. Doing so ensures that ccm_root can log on remotely without a password in either direction.

For example, type ccm_root in the database server hosts.equiv file as a trusted user from machines solaris1 and aix1, as follows:

aix1 ccm_root
solaris1 ccm_root

Use either /etc/hosts.equiv or each user .rhosts, whichever is appropriate for your network security requirements.
