(Reposted from xda-forums. Yes, I plan to do v2 and maybe even release bins..)
No need to use telnet anymore, I ported dropbear sshd over. (Mostly just mangled up the authentication.)
I provide the patch with basically no support, and reserve the right to ridicule you if you ask stupid questions. (If I described something incorrectly or you have actual questions, thats different. But if you aren't comfortable cross-compiling code - or compiling it at all - then this is not for you.)
It isn't plug and play, its a patch to the dropbear shipped with the Android platform code and you are on your own getting it to cross-compile. (I used the sourcery pack.) My build is MULTICALL=1 STATIC=1 and includes dbclient, dropbear, dropbearkey. You'll want to set the root password in debug.h and follow the instructions in the patch.
Latest patch attached.
# A couple of hints for this script.
# debug.h - you want to set a password at the bottom
# I prefer to build STATIC=1 MULTICALL=1 but you can do what you want.
#
# It still checks /etc/shells so unfortunately you have to create that file
# and put your shell in it. (by default I use /system/bin/rootsh. Which you
# will want to create.)
# If you want key-based authentication, there's some additional prep work:
# /data/dropbear needs to be root:root 744 and
# /data/dropbear/.ssh root:root 700
