I'm writing an application which will use "rsh" to an account on our
local server.  That local server's account will not have any passwords, but
will have (for the shell) a program I'm writing in C.

For the utility/application to work properly, the server will need to know
the user name and host name of the remote machine.  If the remote system
is a Silicon Graphics machine, this is easy (I simply get the REMOTEUSER
and REMOTEHOST environment variables).  But NO such variables exist on
the Suns!!!

How can I get the remote host and remote user names????

The server is a Sun 3/60 running SunOS 4.0.3.  "remote" systems are
SGIs running IRIX 3.3.2, and Suns running both SunOS 4.0.3 and SunOS 4.1.1.

Any suggestions???

Thanks you,
