What is a socket?
Could someone explain to me what a socket is? I see it in many acronyms in context of SSL, etc.
How can I communicate with a Unix domain socket via the shell on Debian Squeeze?
I’m running a Debian Squeeze web server. I’ve installed memcached on it, and configured memcached to listen on a Unix domain socket (at /tmp/memcached.sock), as it only needs to receive messages from the website, which lives on the same server.
How do I list all sockets which are open to remote machines?
A vanilla ss -l lists (on my current machine) lots of open sockets, with various Netid types and many of which are only listening on localhost.
Kernel socket structure and TCP_DIAG
I’m working on a software which connects to a Real Time data server (using TCP) and I have some connections dropping. My guess is that the clients do not read the data coming from the server fast enough. Therefore I would like to monitor my TCP sockets. For this I found the “ss” tool.
How do I reserve ports for my application?
How do I reserve a list of ports for my custom applications?
Are FIFO, pipe & Unix domain socket the same thing in Linux kernel?
I heard that FIFOs are named pipes. And they have exactly the same semantics. On the other hand, I think Unix domain socket is quite similar to pipe (although I’ve never made use of it). So I wonder if they all refer to the same implementation in Linux kernel. Any idea?
Is there a file for each socket?
“Everything is a file” in the UNIX World.
What does the @ symbol denote in the beginning of a unix domain socket path in Linux?
When I run netstat --protocol unix or lsof -U I see that some unix socket paths are prepended with @ symbol, for example, @/tmp/dbus-qj8V39Yrpa. Then when I run ls -l /tmp I don’t see file named dbus-qj8V39Yrpa there.
