+===== ssh mit python =====
+Es gibt mehrere Implementierungen für ssh in python. Das Module ''paramiko'' wird hier vorgestellt.
+Installation:
+<code>
+python3 -m pip --proxy https://192.168.21.91:3128 install --user paramiko
+</code>
+Beispiel-Script:
+<file python ssh_paramiko_test.py>
+# https://daanlenaerts.com/blog/2016/01/02/python-and-ssh-sending-commands-over-ssh-using-paramiko/
+import paramiko
+USERNAME='schueler'
+PASSWORD='schueler' #kritisch bei offenen Strukturen; hier besser keys verwenden
+HOST='192.168.33.80'
+ssh = paramiko.client.SSHClient()
+ssh.set_missing_host_key_policy(
+ paramiko.AutoAddPolicy())
+ssh.connect(HOST, username=USERNAME, password=PASSWORD)
+stdin, stdout, stderr = ssh.exec_command('ip address print')
+while not stdout.channel.exit_status_ready():
+                # Print data when available
+                if stdout.channel.recv_ready():
+                    alldata = stdout.channel.recv(1024)
+                    prevdata = b"1"
+                    while prevdata:
+                        prevdata = stdout.channel.recv(1024)
+                        alldata += prevdata
+                    print("1:"+str(alldata, "utf8"))
+stdin, stdout, stderr = ssh.exec_command('ip address add address=22.0.0.1/24 interface=ether4')
+while not stdout.channel.exit_status_ready():
+                # Print data when available
+                if stdout.channel.recv_ready():
