c:\> psping -6 [2607:f8b0:4000:811::2004]:80

Enable SSH server on QNX 6.5

This is quick start guide how to run ssh server on QNX. Tested on QNX 6.5 (650SP1-VM.tar).

# ssh-keygen -t dsa -b 1024 -f /etc/ssh/ssh_host_dsa_key -N ''
# ssh-keygen -t rsa -b 1024 -f /etc/ssh/ssh_host_rsa_key -N ''

This is not security best practice but this is only a test machine. Enable direct root ssh login to the machine.
# sed -i 's/#PermitRootLogin no/PermitRootLogin yes/g' /etc/ssh/sshd_config

Start ssh service
# /usr/sbin/sshd

Use /usr/sbin/sshd -ddd to view debug output
