- use nmap to find where you have Picka [or you can try to find it as next to bridge ip]
- Scan for every TCP and UDP open port:
sudo nmap -n -PN -sT -sU -p- remote_host

MacOSX Backup & restore Banana PI SD card
Backup
# to list partitions diskutil list #/dev/disk4 (internal, physical): # #: TYPE NAME SIZE IDENTIFIER # 0: FDisk_partition_scheme *7.9 GB disk4 # 1: Windows_FAT_32 boot 58.7 MB disk4s1 # 2: Linux 7.9 GB disk4s2 #in our case it was /dev/disk4 #CTRL+T as SIGINFO could be used to check progress sudo dd if=/dev/disk4 bs=1m | gzip > ~/1_Labka/banana_picka_25.5.2016.img.gz
example how to copy backup by scp
copy to remote host
scp ~/1_Labka/banana_picka_25.5.2016.img.gz user@remotehost:/home/share/Picky_Backup/
copy to localhost
scp your_username@remotehost:/home/share/Picky_Backup/banana_picka_25.5.2016.img.gz /some/local/directory
Restore
- remember, SD card should be unmounted
# first check where SD card is visible, but not mounted by diskutil list # let it be again /dev/disk4 gzip -dc ~/1_Labka/banana_picka_25.5.2016.img.gz | sudo dd of=/dev/disk4 bs=1m
remove password to ssh

- ssh root@IP
- password is bananapi
mkdir ~/.ssh chmod 700 ~/.ssh touch ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys
example of generating key to non standard position
over@darkstar>mkdir ~/ssh_tmp ssh-keygen -t rsa -C "tpetru@gmail.com" -f ~/ssh_tmp/id_rsa_na_jine_misto Generating public/private rsa key pair. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/over/ssh_tmp/id_rsa_na_jine_misto Your public key has been saved in /home/over/ssh_tmp/id_rsa_na_jine_misto.pub. The key fingerprint is: SHA256:hriECJShFg+8AKVHVkoqYtBknvhf/sGW+KQr4wqtEUE tpetru@gmail.com The key's randomart image is: +---[RSA 2048]----+ |=EX.. | |*%=o | |@o*. | |** . . . | |o o o o S | | o o + + . | |o . o o * | | + o * . | |. .o.oo.o | +----[SHA256]-----+
nano ~/.ssh/authorized_keys <--- copy there public key generated somewhere
this is what you should have:
drwx—— 2 root root 4096 Mar 13 13:23 .ssh
-rw——- 1 root root 209 Mar 13 13:21 authorized_keys
nano /etc/ssh/sshd_config -> PasswordAuthentication no sudo service ssh restart
test by:
ssh root@localhost
if it is asking for key, everything is ok !!! do not disconnect from session before test from outside !!! try from outside:
ssh root@IP_of_pi
when able to connect by key, everything is fine
create ~/.ssh/config for labka
touch ~/.ssh/config chmod 110 ~/.ssh/config
* add there this block of code; user needs to be correctly set up:
Host labka
user [SOME USER PICO]
hostname 193.84.207.21
ForwardX11 yes
* next time, you can connect to server by
ssh labka
instead of
ssh [some_user]@193.84.207.21
add user to wheel group [grant him sudo]
usermod -aG wheel username
Change colour of shell
nano ~/.bashrc
edit to something like this 31m is red:
PS1='\[\e[1;31m\][\u@\h \W]\$\[\e[0m\] '

Pulseaudio
sudo apt-get install pulseaudio pulseaudio-module-zeroconf alsa-utils avahi-daemon pulseaudio-module-zeroconf pulseaudio-utils
The following is what I did just to get it working in per-session mode (not system mode). System mode may work as well, I haven't attempted it. Setting up server will require some more work. I found this information in various places, hopefully gathering it here will help someone.
Install pulseaudio and make sure user (e.g. over) is part of the audio group:
sudo adduser over audio
Change /etc/asound.conf look like the following. This sets up pulseaudio to be used as an alsa device by default so applications use it without any additional configuration. The first two declarations (including the commented one) was in the original file.
pcm.mmap0 {
type mmap_emul;
slave {
pcm "hw:0,0";
}
}
pcm.pulse { type pulse }
ctl.pulse { type pulse }
pcm.!default { type pulse }
ctl.!default { type pulse }
Add the following lines to /etc/pulse/daemon.conf:
default-sample-rate = 48000 resample-method = trivial

To start the pulseaudio server, use:
pulseaudio -k; pulseaudio -D
You might be also be able to set up in system-wide mode with:
sudo pulseaudio --system
To debug, run:
pulseaudio --log-level=debug
To test alsa, run:
amixer -Dpulse
