Error Binding Socket To Interface Address Already In Use

Then I bind to each unicast address, each broadcast address, and to INADDR_ANY as well. It has been pointed out that "A socket is a 5 tuple (proto, local addr, local port, remote addr, remote port). You can have more than one content # scanner. Fast computers do not need this option. Source

Where did this happen for you? Not compiled !! If you are developing some system where a cluster of client programs sit on one machine and contact a variety of different servers, then you would want to foist the responsibility Dec 3, 2009 at 1:46pm UTC jsmith (5804) If you've run your program without the setsockopt() call and have not rebooted or waited long enough, the address will still be in

It probably makes more sense to call this method "Remote Closes First", because otherwise it depends on what you are calling the client and the server. e.g: nc -p 8140 -z -v -n 10.X.X.9 9090 nc -p 8140 -z -v -n 10.X.X.9 9091 nc -p 8140 -z -v -n 10.X.X.9 9092 nc -p 8140 -z -v -n Hot Network Questions How to automatically run a command after exiting ssh Tenant claims they paid rent in cash and that it was stolen from a mailbox.

Option 1 is preferable; this option is # only for users using both transparent proxying and a non-local server # to host this script. # # Individual filter groups can override How To Use So_reuseaddr Short version is, the kernel has a TIME_WAIT state when it is closing a TCP connection graceful, meaning you can't reuse it until that is finished. This is on Sparcs running Solaris 2.4/2.5. This was not obvious.

Also note that under 4.4BSD, if you are binding a multicast address, then SO_REUSEADDR is condisered the same as SO_REUSEPORT (p. 731 of "TCP/IP Illustrated, Volume 2").

huge thank you!

The server can safely close in response to an EOF from the client, however it will also need to set a timeout when it is expecting an EOF in case the That last is necessary to catch packets that are on the wire with INADDR_BROADCAST in the destination. (SO_REUSEADDR is necessary to bind INADDR_ANY as well as the specific addresses.) This gives Actually, like kbw said, I thought that after using setsockopt() we do not have to wait. Describe How Bind Function Works. In many cases simply waiting a few seconds before the server closes will be adequate.
