Thanks, I didn't know that option at all, but I'll add it as seems to work fine. I've 
searched more about it at internet, and some people even thinks this is a 
bug  from Linux sockets implementation. This option seems to be not standard, 
some UNIXes support it, some other support it but doesn't need it to "rebind" the 
socket, and some other does not support it... I've found that, for example : 
 
"--------------------------- 
Now back to the bug in Linux. When you open a socket, you must also call 
the setsockopt() function with the following segment of code: 
 
#ifdef LINUX 
 
opt = 1; len = sizeof(opt); 
setsockopt(sockfd,SOL_SOCKET,SO_REUSEADDR,&opt,&len); 
#endif 
 
 
The #ifdef and #endif statements are necessary only if you want to port the code 
over to systems other than Linux. Some UNIX systems might not support or 
require the SO_REUSEADDR flag. 
 
'----------------------------------------------------------- 
 
So people trying to port GAMBAS to FreeBSD or other systems will need to 
test that socket implementation in their O.S.
