I have the privilege of configuring a new Concurrent 5450 running RTU 5.0 and have run into trouble with the network software. Apparently Concurrent has decided for this new release that the method for validating equivalent hosts used in the past is no longer secure enough. Their customer support people inform me that the format of the .rhosts, and hosts.equiv files has changed. The files now require both host and username, eg.: hostname username According to the online documentatation, either username or hostname may now be replaced by a wildcard asterisk. In practice, all I have been able to make work is: * username This implies that a user with username from any host may log into this account without a password -- not very secure. Also, the support people *think* (and I can confirm) that the equivalence mechanism no longer works for superuser. Remote dumps and that sort of thing can no longer be done as root. The only workaround I have found is to copy an older version of rloginserver over the new version. Anyone else have a better solution? Thanks in advance.

We still have a few machines running RTU 5.0 and are sucessfully using host name only entries in /etc/net/hosts.equiv. In my recollection, we quit using "*" when we made our Internet connection which was about the time of RTU 3.1 or so. We have not yet felt the need to use both hostnames and usernames, but I suspect that we will get there eventually....
