Are you have compiled it for pch? Share it?
I can't compile this right now case i need it from scratch: install linux, install sdk, find right option, compile.
I try it soon.

Best regards

Yes I have compiled it for pch and of course I share it Download

As I said on hddtemp topic (I have also compiled hddtemp ) I haven't a premium rapidshare account so it should be better if someone can host it elsewhere.

@t0nik
People are asking for the dropbear a lot to add it to the CSI.
As you might expect I am way to busy with CSI to maintain every package in it. Could you help me out here and create a package for CSI?
It isn't hard, I will guide you through the process.

Please contact me.

I forget to post something I think interesting.

It's the script I launch after each reboot (the start_app.sh script launched by the ftp server will launch it)

So I put in the /share/.ssh folder:

- the authorized_keys file with my public key
- a .profile file with alias and environment variables
- a etc/dropbear folder with public and private keys of the ssh server

Code:

#!/bin/sh
#
#
#Dropbear SSH server
#

#Copy Host keys
/bin/cp -r /share/.ssh/etc/dropbear /etc
/bin/chown -R root /etc/dropbear
/bin/chmod 700 /etc/dropbear
/bin/chmod 600 /etc/dropbear/*

#Give shell for root
/bin/mkdir -p /root/
/bin/sed -e 's/^\(root:.*\)true$/\1sh/' -i /etc/passwd
/bin/cp /share/.ssh/.profile /root/.profile

#Give shell for nmt
/bin/mkdir -p /home/nmt
/bin/sed -e 's/^\(nmt:.*\)true$/\1sh/' -i /etc/passwd
/bin/cp /share/.ssh/.profile /home/nmt/.profile

#Give keys for root
/bin/mkdir -p /root/.ssh  
/bin/cp /share/.ssh/authorized_keys /root/.ssh
/bin/chown -R root:root /root
/bin/chmod 700 /root
/bin/chmod 700 /root/.ssh
/bin/chmod 600 /root/.ssh/authorized_keys

#Give keys for nmt
/bin/mkdir -p /home/nmt/.ssh
/bin/cp /share/.ssh/authorized_keys /home/nmt/.ssh
/bin/chown -R nmt:nmt /home/nmt
/bin/chmod 700 /home/nmt
/bin/chmod 700 /home/nmt/.ssh
/bin/chmod 600 /home/nmt/.ssh/authorized_keys

#Launch Dropbear (-s disable password logins)
/share/.bin/dropbear -s &

exit 0

Hope it helps

Okay, since nobody want to actively help me to get this in CSI I just started it myself.
I got dropbear up and running, changed the path to /share/Apps/DropBear (for new package format).

I've created a new public-private keypair using PuttyKeyGen.
Saved the public key in the authorized_keys (the one with content: ssh-rsa AAAAB3Nxxxxxx/AMgow== rsa-key-20090426)
Ultimately ending up in /root/.ssh/autorized_keys
and am using the private key for putty.

When I connect using putty I get an "Server refused our key" after entering the "root" username.
Anyone able to help me out here?

Sorry for no answer
Got many task at my work.
You have trouble with dos carriage return, i think.
For this package, imho, it need create a "default keypaire" and strongly recommend to user change it to his own.
I've compiled again dropbear, now version 0.52, but not write any script for CSI yet. I've package dropbear-0.51 long ago and forget some details.
I've been change some source code for correct work on popcorn with deal with its firmware.

Hi Ger Teunis,

Finally, here it is thanks to t0nik (Dmitry Antonov)!
Dropbear SSH server has been added to the CSI.

Installing will take a few minutes to complete
Dropbear will generate a new keypair for optimal security during install.
It will make copies of the keys (the id_rsa_ files) to the root of your harddisk on the nmt, move them to a save location.

Use you perferred ssh client and use the ppk file mentioning root to login as root, nmt file to login as nmt.
This dropbear includes a very complete busybox and midnight commander.

Enjoy!

Is it possible to add sftp support? Inside options.h, there is an option called SFTPSERVER_PATH which should point to the sftp-server from OpenSSH (which can be downloaded at http://packages.debian.org/sid/mipsel/op...download). I would love to have sftp access, but I don't know how to compile this one with the same options as your build (and I do not have any experience in compiling programs for my NMT). It would be great to have sftp-server enabled. Is this possible? Can I help you to achieve this?

Edit:
If you do not have time, I'm also happy with your compile settings - than I can add sftp myself hopefully.

Hi,
I've installed DropBear through CSI (great !) but I encounter a connection problem :
- connection possible with WinSCP (root & nmt users)
- authentication successed but connection failed with different Mac clients :

Code:

subsystem request failed on channel 0

Dropbear logs don't notice any problem.

Anyone's already got that ?

Thx

Hi,

I Did figure out how to use rsync, dropbear with my centos server.
So now I can do a backup of the HDD installed in my Popcorn and store the data/files/movies on my Linux centos 5.2 box.

I have installed "rsync 3.0.4" and "Dropbear 0.52-3" with the help of NMT Community Software Installer (thanx!)

I had to make adjustments etc on howto get rsync to work on the popcorn and also how to get ssh to work from centos to the popcorn.
(thought I may post a separate instructions/howto for this)

what I do;
I run the rsync command on my centos box.
This copies from Popcorn and down to my centos box..
but the rsync (but really it is the ssh login process) takes a very loong time to login to the popcorn.

Is there already a way to speed up this login ? or
Is there a sshd deamon we can tweak on the popcorn, file ?

Thank you all for contributing!! both developers and you other posters!
