Error Binding Socket Address Already In Use


It has happened with me a lot of times. The time now is 08:52 AM. - Contact Us - Unix & Linux - unix commands, linux commands, linux server, linux ubuntu, shell script, linux distros. - Advertising - Top TIME_WAIT is the state that typically ties up the port for several minutes after the process has completed. These are telnet escapes. have a peek at this web-site

This is my Bind part of the Socket program //Bind if( bind(socket_desc,(struct sockaddr *)&server , sizeof(server)) < 0) { //print the error message perror("bind failed. can any one suggest why this happing so when this bind error comes thankx Last edited by bhakti; 07-24-2006 at 05:43 AM..

Bind Failed. Error Address Already In Use

Let me get over being really excited about this and work your methodology into my program... Error: Address already in use I don't know how to fix this problem.. But if any data sending action happens in the server side to the client, the same service(same port) restart will have this error: (Address already in use).

This tells the kernel to let you know when a socket is available for use. Can't Bind Server Socket Address Already In Use On my Linux system it is about 2 minutes.

This ensures that socket resuse is setup BEFORE # it is bound. Go Here Every time I then wait for a few more secs and then it starts working again. Bind Failed.

Additionally, others don't like that a busy server may have hundreds or thousands of these TIME_WAIT sockets stacking up and using kernel resources. Check This Out Without SO_REUSEPORT, only one ftpd thread can bind to TCP (lhost, lport, INADDR_ANY, 0) in preparation for connecting back to the client. I will look into this further in my own program. you can wait or use socket option SO_REUSEADDR as mentioned in another post. Could Not Bind Socket Address Already In Use
