hello, check this code (put it into Eric new file and save)
while it works well with 4-line function myFunction (both variables a and
msg are marked as unused), it fails for more complex _operationByMAC (only
a is marked as unused and msg is not)
def myFunction(operation = 'lock', macAddress = 'A0:B0:C0:D0:E0:F0'):
a = 4
msg = f'operation {operation} with macAddress={macAddress} is finished'
#print(msg)
return r
import paramiko
class EmptyClass:
pass
def _operationByMAC(macAddress=None, operation=None, routerIP = None,
userName = None, password = None):
assert operation in ('unblock', 'block', 'get_state')
r = EmptyClass()
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
r.ssh = ssh
ssh.connect(routerIP, username=userName, password=password)
command = f'ip firewall filter print where
src-mac-address="{macAddress}"'
stdin, stdout, stderr = ssh.exec_command(command)
result = stdout.read().decode()
lines = result.split('\n')
RuleLine = None
for line in lines:
if 'src-mac-address='+macAddress in line:
RuleLine = line
break
if RuleLine is None:
match operation:
case 'get_state':
r.state = 'unblocked'
print(f'{macAddress} is unblocked')
return r
case 'block':
pass
case 'unblock':
msg = 'Error: this MAC was not found in firewall rules'
print(msg)
r.msg = msg
r.state = 'unblocked'
return r
a = 3
msg = f'operation {operation} with macAddress={macAddress} is finished'
#print(msg)
return r
