[Resolved] I can't use rsync in both sides

Modest Polykarpovich

Hello all. Now I setup cross-compiler on a virtual machine and rsync utility that need to copy binary files after compilation to the Omega2.

There are next problems:

I can't install rsync on the Omega2, look at the errors below.

Next. At my cross-compile virtual-machine (Debian 9). The RSA-keys to connect without password are not working, but the key appends into file /root/.ssh/authorized_keys as normal. After connection I must already type a password.

I've install rsync utility on Onion Omega2+ Pro. Look at the rigth command below:

opkg update && opkg install --nodeps rsync

The problem is in conflict of libpopt, but it is already installed by firmware OS.

But I can't connect via rsync:// protocol. Authorization is already failed. These are my rsyncd.conf file and command to run rsync as daemon:

rsync --daemon

List of my file /etc/rsyncd.conf

root@Omega-D913:~# cat /etc/rsyncd.conf
uid = root
gid = root
use chroot = no
max connections = 4
syslog facility = local5

[myprojects]
        path = /root/projects
        comment = My folder with projects C, C++

See to the successful connection to Omega2+ from my Debian Virtual Machine.

vladimir@debian-dev:~/projects/ac_template$ rsync -avz ./config.log rsync://root@192.168.31.123
myprojects      My folder with projects C, C++

Here is myprojects preset

Then I try to sync...

vladimir@debian-dev:~/projects/ac_template$ rsync -avz ./config.log rsync://root@192.168.31.123:/myprojects

On the onion, you need to put the keys in /etc/dropbear/authorized_keys. Maybe you're doing this -- it's not clear. I can say is that I use rsync to upload my distro to Omega2+, and it works. So whatever you're doing is fixable.

Many Thanks - it's work!
