Socket bind permission denied python
Not sure if it matters but my python files are in Desktop dir.
You should use Apache, nginx, etc. From the Bottle docs :. This non-threading HTTP server is perfectly fine for development and early production, but may become a performance bottleneck when server load increases. There are three ways to eliminate this bottleneck:. Have you considered using sudo? You could configure sudoers to securely allow user "pi" to execute only gggg.
Thanks to Wooble I realised that permission error had to do with the port and not the file system. A working workaround is to use port above which works perfectly and is fine for development. Using port for now:. How are we doing? Please help us improve Stack Overflow. Take our short survey.

This uses the Internet TCP protocol, which provides for continuous streams of data between the client and server. The other parameters are passed to the BaseServer base class. This uses datagrams, which are discrete packets of information that may arrive out of order or be lost while in transit.
The parameters are the same as for TCPServer. These four classes process requests synchronously ; each request must be completed before the next request can be started. The solution is to create a separate process or thread to handle each request; the ForkingMixIn and ThreadingMixIn mix-in classes can be used to support asynchronous behaviour.
Creating a server requires several steps. First, you must create a request handler class by subclassing the BaseRequestHandler class and overriding its handle method; this method will process incoming requests. It is recommended to use the server in a with statement. When inheriting from ThreadingMixIn for threaded connection behavior, you should explicitly declare how you want your threads to behave on an abrupt shutdown. You should set the flag explicitly if you would like threads to behave autonomously; the default is Falsemeaning that Python will not exit until all threads created by ThreadingMixIn have exited.
Server classes have the same external methods and attributes, no matter what network protocol they use. There are five classes in an inheritance diagram, four of which represent synchronous servers of four types:. Forking and threading versions of each type of server can be created using these mix-in classes.
The mix-in class comes first, since it overrides a method defined in UDPServer. Setting the various attributes also changes the behavior of the underlying server mechanism. Use daemonic threads by setting ThreadingMixIn. Changed in version 3. Add a new socketserver. To implement a service, you must derive a class from BaseRequestHandler and redefine its handle method.
You can then run various versions of the service by combining one of the server classes with your request handler class. The request handler class must be different for datagram or stream services. Of course, you still have to use your head! For instance, it makes no sense to use a forking server if the service contains state in memory that can be modified by different requests, since the modifications in the child process would never reach the initial state kept in the parent process and passed to each child.
In this case, you can use a threading server, but you will probably have to use locks to protect the integrity of the shared data.
Here a threading or forking server is appropriate. In some cases, it may be appropriate to process part of a request synchronously, but to finish processing in a forked child depending on the request data. This can be implemented by using a synchronous server and doing an explicit fork in the request handler class handle method.
Another approach to handling multiple simultaneous requests in an environment that supports neither threads nor fork or where these are too expensive or inappropriate for the service is to maintain an explicit table of partially finished requests and to use selectors to decide which request to work on next or whether to handle a new incoming request.
This is particularly important for stream services where each client can potentially be connected for a long time if threads or subprocesses cannot be used. See asyncore for another way to manage this. This is the superclass of all Server objects in the module.This module provides access to the BSD socket interface.
Some behavior may be platform dependent, since calls are made to the operating system socket APIs.
For an introduction to socket programming in Csee the following papers: An Introductory 4. The platform-specific reference material for the various socket-related system calls are also a valuable source of information on the details of socket semantics. Parameter types are somewhat higher-level than in the C interface: as with read and write operations on Python files, buffer allocation on receive operations is automatic, and buffer length is implicit on send operations.
For socket module methods, flowinfo and scopeid can be omitted just for backward compatibility. Note, however, omission of scopeid can cause problems in manipulating scoped IPv6 addresses. Other address families are currently not supported. The address format required by a particular socket object is automatically selected based on the address family specified when the socket object was created.
The behavior is not available for IPv6 for backward compatibility, therefore, you may want to avoid these if you intend to support IPv6 with your Python programs. For deterministic behavior use a numeric address in host portion. New in version 2. TIPC is an open, non-IP based networked protocol designed for use in clustered computer environments. Addresses are represented by a tuple, and the fields depend on the address type.
All errors raise exceptions. The normal exceptions for invalid argument types and out-of-memory conditions can be raised; errors related to socket or address semantics raise the error socket. Non-blocking mode is supported through setblocking. A generalization of this based on timeouts is supported through settimeout.
The module socket exports the following constants and functions:. This exception is raised for socket-related errors. The accompanying value is either a string telling what went wrong or a pair errno, string representing an error returned by a system call, similar to the value accompanying os. See the module errnowhich contains names for the error codes defined by the underlying operating system. Changed in version 2. This exception is raised for address-related errors, i. This exception is raised for address-related errors, for getaddrinfo and getnameinfo.
The accompanying value is a pair error, string representing an error returned by a library call. This exception is raised when a timeout occurs on a socket which has had timeouts enabled via a prior call to settimeout. These constants represent the address and protocol families, used for the first argument to socket.
These constants represent the socket types, used for the second argument to socket. They are generally used in arguments to the setsockopt and getsockopt methods of socket objects. In most cases, only those symbols that are defined in the Unix header files are defined; for a few symbols, default values are provided.
The constants are used as arguments to the ioctl method of socket objects. See the TIPC documentation for more information. Connect to a TCP service listening on the Internet address a 2-tuple host, portand return the socket object.
This is a higher-level function than socket. This makes it easy to write clients that are compatible to both IPv4 and IPv6. Passing the optional timeout parameter will set the timeout on the socket instance before attempting to connect. If no timeout is supplied, the global default timeout setting returned by getdefaulttimeout is used. The familysocktype and proto arguments can be optionally specified in order to narrow the list of addresses returned.Share your knowledge at the LQ Wiki.

I have also tried other ports too - no luck. Running cvlc with root doesn't help either and that is not recommended by the documentation.

Bind911 - could not listen on UDP socket: permission denied
It only takes a minute to sign up. I've recently rebooted one of my machines after a long time and a now I'm having a lot of problems with configuration changes. No other process is running in portas I said when I try to run command manually it works perfectly.
If you want to run syslog-ng on differrent port, you have to change ports labels. As Alexander pointed the problem was that SELinux was blocking the port but I'm receiving the logs in so i cannot change it. The solution was to set SELinux from enforcing to permissive with setenforce 0.

I have made a Linux program that sends UDP packets to a lighting controller. I configured an ethernet port to have a static IP address with the correct netmask.
The ethernet cable pugs straight from the controller device into the Pi. I edited the dhcpcd. The device's IP is Is there some additional network configuration I should try that includes specifying the netmask or something? I do need to be able to broadcast though so still looking for a solution Static addresses have nothing to do with it.
Sending to a broadcast address is a privileged operation. Are you sure about your network mask? Sign up to join this community. The best answers are voted up and rise to the top.

I don't know why you want static address, but it might work if you used a consistent network setting.
