It there a way to create or close in some cool way to avoid bind error? c sockets bind share|improve this question asked Apr 8 '11 at 8:53 spe 38751222 add a comment| 4 Answers 4 active oldest votes up vote 15 down vote accepted Somewhere in the kernel, there's still some information about your previous socket hanging around. Tell the kernel that you are willing to re-use the port anyway: int yes=1; //char yes='1'; // use this under Solaris if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &yes, sizeof(yes)) == -1) { perror("setsockopt"); exit(1); } See the bind() section in beej's Guide to Network Programming for a more detailed explanation. share|improve this answer answered Apr 8 '11 at 9:01 Philip 3,6251857 add a comment| up vote 1 down vote This is the expected behavior for TCP sockets. When you close a socket it goes to the TIME_WAIT state. It will accept and drop packets for this port. You need to set the SO_REUSEADDR option to bind immediately again. share|improve this answer answered Apr 8 '11 at 9:00 harper 8,46842867

This is the code: Code: .... struct sockaddr_in adresa; struct sockaddr client; .... int server_listen(int nport,char *bufferaddr) { printf("server listen\n"); buffer=bufferaddr; if(sd=socket(AF_INET,SOCK_DGRAM,0)==-1) {printf("pas 1\n");return -1;} adresa.sin_family=AF_INET; adresa.sin_addr.s_addr=htonl(INADDR_ANY); //using any address adresa.sin_port=htons(nport);//using the specified port //next is the problem if(bind(sd,(struct sockaddr*)&client,sizeof(struct sockaddr))==-1) {printf("pas 2 %i\n",errno);return -1;} return 1; } And also where can I find a list with the error codes Thx.

The problem is on this line bind(sckHandle, (struct sockaddr*)(SvrAddress), sizeof(sockaddr_in)) except that this line is ok. I found on a forum a problem similar and the dude answered that it was solved, it was a problem with his firewall settings on linux. I searched to modify them with FireStarter but could not find where was the problem. I hope you guys can help me, thanks in advance. Nov 4, 2010 at 8:57am UTC kbw (7986) What is the declaration for SvrAddress? Nov 4, 2010 at 12:32pm UTC kool (5) sockaddr_in* SvrAddress; and i initialized it with 1

SvrAddress = new sockaddr_in; SvrAddress->sin_family = AF_INET; SvrAddress->sin_addr.s_addr = htonl(ip); SvrAddress->sin_port htons(port); Last edited on Nov 4, 2010 at 12:32pm UTC Nov 4, 2010 at 1:37pm UTC jsmith (5804) What error are you getting? (errno) Nov 4, 2010 at 1:40pm UTC kool (5) the result from bind is -1, if it's what u'r asking for. Nov 4, 2010 at 4:43pm UTC jsmith (5804) No, I'm asking for the value of errno. Nov 5, 2010 at 2:16am UTC kool (5) Well i don't know 'cause i didn't manage to find how it works, but i found the error str "Address Already In Use" But who would use the port 7153 and the IP address is equivalent to INADDR_ANY Nov 5, 2010 at 1:33pm UTC jsmith (5804) netstat -ap | grep 7153 will tell you which process. Are you, by any chance opening two sockets and attempting to bind both to the same port? Nov 5, 2010 at 1:43pm UTC Galik (2250) It may be that the port is being held from a previous run of your program. Sometimes it takes time for it to be released. Don't know why. Nov 5, 2010 at 2:17pm UTC jsmith (5804) Machine A does that because it wants to give the other side (machine B) time to realize that machine A is no longer responding and close its side of the connection. Otherwise, if a different process starts on Machine A and opens the same port, it will receive packets that it can't comprehend. To turn off this behavior, you have to set the SO_REUSEADDR socket option. Nov 5, 2010 at 2:42pm UTC kool (5) Thanks for your precious help. 1. It was from a previous process wrong terminated. I guess CodeLite don't terminate the process it started when it crashes. 2. it is possible to check at Application startup if another process of the same name is open ?
