I have had the very same problem, and can tell you exactly what your problem
is. RedHat distributes /usr/bin/dos as suid root, and /etc/dosemu.users such
that it contains:
nobody nosuidroot guest
guest nosuidroot guest
# If you want to allow limited dosemu to all users, uncomment the line
# all nosuidroot restricted
"nosuidroot" means that a regular user will get exactly the symptoms you
describe if he is attempting to run a suid root copy of DOSEMU. You have four
choices: First, remove the "nosuidroot" directive. Second, always run DOSEMU as
root. Third, remove the suid bit from /usr/bin/dos. Fourth, copy /usr/bin/dos
to another location as non-suid.
