Slacker may be correct that Dropbear is a better solution. I plan to look at that at some point . I did manage to get ssh working.

First it seemd that in a uClinux environment the ssh daemon expects to be launched from inetd. So I modified the ssh makefile in

uClinux-dist/user/ssh to add a line in the inetd.conf file to launch the Daemon.

$(ROMFSINST) -e CONFIG_USER_SSH_SSHD -a "ssh stream tcp nowait root /bin/sshd -i" /etc/inetd.conf

I am using a simple sshd_config file:

Port 22

Protocol 2

AddressFamily inet

I generated the host keys on my PC Linux workstation and copied them into the jffs2 file system. The RC file copies them into the /etc directory. Not very efficient.

To start an ssh session from my workstation on the nios2 target I type:

ssh -x -l root -T <IP ADDRESS>

As mentioned in the initial post, I enabled the three ssh utilities in Network Applications.

I did not need to explicitly enable ssl. There was some documentation around that indicated that it was needed. If so it is picked up automatically.
