It's correct that I didn't attach a "cygcheck -svr" report. I can say,
however, that the machines on which I have observed this problem were
running Windows 2000 and 'OpenSSH_3.7.1p2'.
I see what must be the code to create the directory with the proper
permissions/ownership:
.
.
.
# Check if running on NT
_sys="`uname -a`"
_nt=`expr "$_sys" : "CYGWIN_NT"`
.
.
.
# Create /var/empty file used as chroot jail for privilege separation
if [ -f /var/empty ]
then
echo "Creating /var/empty failed\!"
else
mkdir -p /var/empty
# On NT change ownership of that dir to user "system"
if [ $_nt -gt 0 ]
then
chmod 755 /var/empty
chown system.system /var/empty
fi
fi
.
.
Should the 'chown' line be 'chown system.root' instead? Anyway, if I have to
install 'sshd' again, I will pay close attention to what happens here.
Thanks for the suggestions.
