hi,
i just had the problem with the sftp login on TinyCore v12.86x
from the file /usr/local/etc/ssh/sshd_config:
# override default of no subsystems
Subsystem sftp /usr/libexec/sftp-server
with that line sftp login didn't work, cause there isn't a directory named libexec
when adding the following line and reboot, it does work
# override default of no subsystems
#Subsystem sftp /usr/libexec/sftp-server
Subsystem sftp /usr/local/lib/openssh/sftp-server
i don't know if that is a bug or i am missing something new
