README

1This is Dropbear, a smallish SSH 2 server and client.
2
3INSTALL has compilation instructions.
4
5MULTI has instructions on making a multi-purpose binary (ie a single binary
6which performs multiple tasks, to save disk space)
7
8SMALL has some tips on creating small binaries.
9
10See TODO for a few of the things I know need looking at, and please contact
11me if you have any questions/bugs found/features/ideas/comments etc :)

17In the absence of detailed documentation, some notes follow:
18============================================================================
19
20Server public key auth:
21
22You can use ~/.ssh/authorized_keys in the same way as with OpenSSH, just put
23the key entries in that file. They should be of the form:
24
25ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAwVa6M6cGVmUcLl2cFzkxEoJd06Ub4bVDsYrWvXhvUV+ZAM9uGuewZBDoAqNKJxoIn0Hyd0Nk/yU99UVv6NWV/5YSHtnf35LKds56j7cuzoQpFIdjNwdxAN0PCET/MG8qyskG/2IE2DPNIaJ3Wy+Ws4IZEgdJgPlTYUBWWtCWOGc= someone@hostname
26
27You must make sure that ~/.ssh, and the key file, are only writable by the
28user. Beware of editors that split the key into multiple lines.
29
30NOTE: Dropbear ignores authorized_keys options such as those described in the
31OpenSSH sshd manpage, and will not allow a login for these keys. 
32
33============================================================================
34
35Client public key auth:
36
37Dropbear can do public key auth as a client, but you will have to convert
38OpenSSH style keys to Dropbear format, or use dropbearkey to create them.
39
40If you have an OpenSSH-style private key ~/.ssh/id_rsa, you need to do:
41
42dropbearconvert openssh dropbear ~/.ssh/id_rsa  ~/.ssh/id_rsa.db
43dbclient -i ~/.ssh/id_rsa.db <hostname>
44
45Currently encrypted keys aren't supported, neither is agent forwarding. At some
46stage both hopefully will be.
47
48============================================================================
49
50If you want to get the public-key portion of a Dropbear private key, look at
51dropbearkey's '-y' option.
52
53============================================================================
54
55To run the server, you need to generate server keys, this is one-off:
56./dropbearkey -t rsa -f dropbear_rsa_host_key
57./dropbearkey -t dss -f dropbear_dss_host_key
58
59or alternatively convert OpenSSH keys to Dropbear:
60./dropbearconvert openssh dropbear /etc/ssh/ssh_host_dsa_key dropbear_dss_host_key
61
62============================================================================
63
64If the server is run as non-root, you most likely won't be able to allocate a
65pty, and you cannot login as any user other than that running the daemon
66(obviously). Shadow passwords will also be unusable as non-root.
67
68============================================================================
69
70The Dropbear distribution includes a standalone version of OpenSSH's scp
71program. You can compile it with "make scp", you may want to change the path
72of the ssh binary, specified by _PATH_SSH_PROGRAM in options.h . By default
73the progress meter isn't compiled in to save space, you can enable it by 
74adding 'SCPPROGRESS=1' to the make commandline.
