Running snmpfwd-server in Windows

JorgeJuanTel commented 5 years ago

Hi

I'm trying to run snmpfwd-server in Windows but when I execute it in a console window nothing happens. No matter what parameters I put, it does not do anything (except the version and help parameters that do work) .

I'm using the example SNMPv3 to SNMPv1 proxy server configuration file. This file is located in the directory "c:\tmp". In the next example, I run the command three times. The first time to check the script printing the version. The second and third time, passing the configuration file with a relative path or with an absolute path.

C:\tmp> C:\tmp> C:\tmp>snmpfwd-server.py --config-file=server.conf

C:\tmp> C:\tmp>snmpfwd-server.py --config-file=c:\tmp\server.conf

C:\tmp>

Also I have tried to put the parameters logging-method, log-level and debug-snmp but nothing has worked. Maybe it is a problem of windows permissions, but at this moment I have run out of ideas. My operating system is Windows 10 and my user is an administrator of the machine.

I would appreciate any help. Best regards,

Jorge

I personally do not have much experience with Windows logging.

Let's may be start with something simple e.g. --logging-method=file:snmpfwd.log? Though the default is stderr, may be also try --logging-method=stdout? It may also have something to do with user permissions.. Sorry, I do not have anything more specific to offer off the top of my head.

If you could debug that any further to come up with a fix, that would be useful! The code to start with is perhaps here.

Thank very much. I have debugged the code and the problem is in the function PrivilegesOf. The debugger says: AttributeError: module 'snmpfwd.daemon' has no attribute 'PrivilegesOf' I have seen in the daemon.py file that PrivilegesOf is not defined for Windows:

if sys.platform[:3] == 'win': def daemonize(pidfile): raise error.SnmpfwdError('Windows is not inhabited with daemons!') def dropPrivileges(uname, gname): return else:

Is it correct? Maybe I have an old version of daemon.py. I have to tell you that I am a beginner with Python.

In any case, I have defined the class PrivilegesOf inside the 'if sys.platform[:3] == 'win':' and, it works now.

Thank you Best regards,

Jorge

I ran into the same issue as Jorge. His solution worked for me. I wish I noticed that it was in the daemon.py script file as I was looking in the wrong place. I am new to Python as well so I'm not sure if I fixed it in the cleanest way.

I am running snmpfwd version 0.4.4 with Python 3.8 on Windows 10 for testing.

For those attempting the same (with a pip installation), the file is located here:

\Lib\site-packages\snmpfwd\daemon.py Original Code Block: ``` if sys.platform[:3] == 'win': def daemonize(pidfile): raise error.SnmpfwdError('Windows is not inhabited with daemons!') def dropPrivileges(uname, gname): return else: import os # original code continues... ``` Work around code changes: ``` if sys.platform[:3] == 'win': def daemonize(pidfile): raise error.SnmpfwdError('Windows is not inhabited with daemons!') def dropPrivileges(uname, gname): return class PrivilegesOf(object): def __init__(self, uname, gname, final=False): return def __enter__(self): return def __exit__(self, *args): return else: import os # original code continues... ``` Hopefully a correction can be added to the source code (by someone more familiar with Python than me).
