Problem solved. If i link it correctly against -lutil it works. So i can
report, i have working rshd, rlogind, rsh and rlogin for your linux system.
do you want to include it to your repository?
i would love to provide you the sources.
regards, chris

I integrated new applications into the build process by making a directory under \
uClinux-dist/user with traditional Makefile and adding application-specific options \
to uClinux-dist/user/Kconfig and uClinux-dist/user/Makefile . To build applications \
independently, I reproduced the environment at the time of the build and used it in a \
wrapper script that runs build only for the current directory but with environment \
that should be set at the build time. Unfortunately this local build procedure is \
ridiculously ugly and should be replaced with something better before I can recommend \
it for anyone else to use.<div>
