README

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

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