-## Dropbear SSH
-A smallish SSH server and client
-https://matt.ucc.asn.au/dropbear/dropbear.html
+# ssh-daemon-project
 
-[INSTALL.md](INSTALL.md) has compilation instructions.
+`ssh-daemon-project` is the standalone Dropbear source tree adapted for ELKS on
+16-bit IA16 systems.
 
-[MULTI.md](MULTI.md) has instructions on making a multi-purpose binary (ie a single binary which performs multiple tasks, to save disk space).
+## Platform
 
-[SMALL.md](SMALL.md) has some tips on creating small binaries.
+- ELKS on 8086, 8088, 80186, 80188, 80286 and compatible CPUs
+- QEMU ELKS images and real XT/AT class hardware
+- `ia16-elf-gcc` extapp builds
 
-A mirror of the Dropbear website and tarballs is available at https://dropbear.nl/mirror/.
+## What This Repository Contains
 
-Please contact me if you have any questions/bugs found/features/ideas/comments etc
-There is also a mailing list https://lists.ucc.asn.au/mailman/listinfo/dropbear
+- the Dropbear source tree
+- `Makefile.elks` and ELKS-specific configuration
+- ELKS networking compatibility fixes for the client path
+- the `dbclient` SSH client build used by ELKS images and smoke tests
 
-Matt Johnston
-matt@ucc.asn.au
+The main ELKS deliverable from this repository is `dbclient`.
+The full source tree is kept because the QEMU test harness also builds a host
+Dropbear server fixture from the same source base.
 
+## Relationship To ELKS Enhanced
 
-### In the absence of detailed documentation, some notes follow
-
-----
-#### Server public key auth
-
-You can use `~/.ssh/authorized_keys` in the same way as with OpenSSH, just put the key entries in that file.
-They should be of the form:
-
-    ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAwVa6M6cGVmUcLl2cFzkxEoJd06Ub4bVDsYrWvXhvUV+ZAM9uGuewZBDoAqNKJxoIn0Hyd0NkyU99UVv6NWV/5YSHtnf35LKds56j7cuzoQpFIdjNwdxAN0PCET/MG8qyskG/2IE2DPNIaJ3Wy+Ws4IZEgdJgPlTYUBWWtCWOGc= someone@hostname
-
-You must make sure that `~/.ssh`, and the key file, are only writable by the user.
-Beware of editors that split the key into multiple lines.
-
-Dropbear supports some options for authorized_keys entries, see the manpage.
-
-----
-#### Client public key auth
-
-Dropbear can do public key auth as a client.
-But you will have to convert OpenSSH style keys to Dropbear format, or use dropbearkey to create them.
-
-If you have an OpenSSH-style private key `~/.ssh/id_rsa`, you need to do:
-
-```sh
-dropbearconvert openssh dropbear ~/.ssh/id_rsa  ~/.ssh/id_rsa.db
-dbclient -i ~/.ssh/id_rsa.db <hostname>
-```
-
-Dropbear does not support encrypted hostkeys though can connect to ssh-agent.
-
-----
-If you want to get the public-key portion of a Dropbear private key, look at dropbearkey's `-y` option.
-It will print both public key and fingerprint. If you need the pub key only you can grep by a prefix `ssh-`: 
-```sh
-./dropbearkey -y -f ~/.ssh/id_ed25519 | grep "^ssh-" > ~/.ssh/id_ed25519.pub
-```
-
-----
-To run the server, you need to generate server keys, this is one-off:
-
-```sh
-./dropbearkey -t rsa -f dropbear_rsa_host_key
-./dropbearkey -t dss -f dropbear_dss_host_key
-./dropbearkey -t ecdsa -f dropbear_ecdsa_host_key
-./dropbearkey -t ed25519 -f dropbear_ed25519_host_key
-```
-
-Or alternatively convert OpenSSH keys to Dropbear:
-
-```sh
-./dropbearconvert openssh dropbear /etc/ssh/ssh_host_dsa_key dropbear_dss_host_key
-```
-
-You can also get Dropbear to create keys when the first connection is made - this is preferable to generating keys when the system boots.
-Make sure `/etc/dropbear/` exists and then pass `-R` to the dropbear server.
-
-----
-If the server is run as non-root, you most likely won't be able to allocate a pty, and you cannot login as any user other than that running the daemon (obviously).
-Shadow passwords will also be unusable as non-root.
-
-----
-The Dropbear distribution includes a standalone version of OpenSSH's `scp` program.
-You can compile it with `make scp`.
-You may want to change the path of the ssh binary, specified by `_PATH_SSH_PROGRAM` in `options.h`.
-By default the progress meter isn't compiled in to save space, you can enable it by adding `SCPPROGRESS=1` to the `make` commandline.
+This repository is separate from `elks-enhanced`.
+The main ELKS tree keeps the menuconfig and install hooks for the Dropbear
+extapp, but the source is fetched into `extapps%
