* configuration is in /etc/ssh/sshd_config
* all logins are documented in /var/log/auth.log

 Aug 13 08:09:02 raspberrypi CRON[29805]: pam_unix(cron:session): session closed for user root
* SSH credentials (e.g. for WinSCP or Putty) for user=pi pwd=Halloo0@1 (old raspberry) 
* enable SSH access for root with pwd Halloo0@1 by
 sudo su
 passwd Halloo0@1
 // edit /etc/ssh/sshd_config
 // decommend PermitRootLogin without-password
 // add PermitRootLogin yes
 sudo service ssh restart
* to just enable root for ssh 
 copy /etc/ssh/sshd_config to /etc/ssh/sshd_config_2019-08-18
 add to ssh_config
    # added by UH 2019-18-08 10:05
    AllowUsers root
 restart service by 
    sudo service ssh restart
* cmd line access via fritzbox by 
 ssh root@uweheuer.spdns.de -p 54444
* or use WinSCP

===SD Card===
* SD Card is file /dev/mmcblk0 and mmcblk0p[1-7] are the partitions, see them
 fdisk /dev/mmcblk0
 p
 q

===Timezone===
set to Berlin by:
 sudo timedatectl set-timezone Europe/Berlin
check with
 timedatectl

===USB stick 1===
* pluged-in 64GB USB stick -> USB stick is sda1 (see lsblk)
* windows partition table changed to Linux according to [http://www.netzmafia.de/skripten/hardware/RasPi/RasPi_Laufwerke.html here]
* format USB stick to ext4 filesystem by 
 umount /dev/sda1
 mkfs.ext4 /dev/sda1 -L USBSTICK
* mount the USB stick by
 cd /media
 mkdir usbstick
 mount /dev/sda1 /media/usbstick
* make the mount permanent by
 nano -Bw /etc/fstab
 add line /dev/sda1 /media/usbdisk auto defaults,user 0 1

===USB stick 2===
* pluged-in 128GB USB stick for backup of raspberry -> USB stick device is sdb, partition is sdb1 (see output of tail -f /var/log/messages)
* the stick is formatted with FAT filesystem and is changed to ext4 by:
 fdisk /dev/sdb
 d
 n + p
 w
 reboot
 mkfs.ext4 /dev/sdb1 -L USBSTICK2
* mount it 
 cd /media
 mkdir usbstick2
 mount /dev/sda1 /media/usbstick2
* and for mounting it permanently add the following line /etc/fstab
 /dev/sdb1 /media/usbstick2 auto defaults,user 0 1

===Fritz NAS===
