Dear Krad,
Thank you for your reply, regarding your answer, i have few questions here
1-
in sshd_config file the default line is :
Subsystem sftp /usr/libexec/sftp-server
So should i comment out the line? or just add your line ?
Subsystem sftp internal-sftp
2- the SSH is the default one that comes with FreeBSD, I ofcourse didnot compile
SSH in the system. Are you asking me to install additional packages?
or to recompile ssh when you wrote :
"Make sure chroot support was compiled in"
3- SSH users are using passwords not keygen, where do i get the keys for thier
login?
Thank you
