WARNINGS

There is no way to specify options to the

socket() call that rexec() makes.

A program using

rexec() should not be put in the background when

rexec() is expected to prompt for

a password or user name. Putting

rexec() in the background will cause it to compete with the current

shell process for input.

Since rexec() replaces the pointer to the host name (*ahost) with a pointer to the standard name of the

host in a static data area, this value must be copied into the user’s data area if it is to be used later.

The password is sent unencrypted through the socket connection.
