loopback

How do I have a socket accept connections only from the localhost (in Java)?

I have a java app (not running in any application container) which listens on a ServerSocket for connections. I would like it to only accept connections which come from localhost. Currently, after a connection is accepted, it checks the peer IP and rejects it if it is not the loopback address, but I know that peer IP addresses can be s...

TIME_WAIT on Loopback Interface

Why is it that TCP connections to a loopback interface end up in TIME_WAIT (socket closed with SO_DONTLINGER set), but identical connections to a different host do not end up in TIME_WAIT (they are reset/destroyed immediately)? Here are scenarios to illustrate: (A) Two applications, a client and a server, are both running on the same ...

Can't access localhost/iis after installing Oracle and loopback adaptor

Recently I installed Oracle and the required Microsoft Loopback Adaptor, which worked fine. However, this seems to have screwed up IIS (or at least its interaction with Visual Studio) somehow.

What is the purpose of the Microsoft Loopback Adapter?

Just as the question says, what is the Microsoft Loopback Adapter, and as a bonus, what scenerios as a developer would it be useful?

Bidirectional/Loopback UDP in .net

I've got an app that needs to transmit and receive on the same port. This can happen in two cases: Where the PC is talking to a piece of remote hardware. It "replies to sender", so the datagrams come back in to my PC via the sending port. Where the PC is talking to itself (loopback mode) for testing and demoing (a test app feeds fake d...

Loopback connections working in user's context but not working from Local System account

We have a networking application that can run from a service account as well as a regular user's account. The app tries to open up a loopback connection to another service running on the local machine. So for example it tries to connect to: 127.0.0.1 port 2000.

Serial port loopback/duplex test, in Bash or C? (process substitution)

Hi all, I have a serial device set up as loopback (meaning it will simply echo back any character it receives), and I'd like to measure effective throughput speed. For this, I hoped I could use time, as in time bash -c '...' where '...' would be some command I could run. Now, the first problem is that I want to use the device at 2...

I know it's possible to bind multiple IP ...
