Hello Mahmoud et All,
When I run Ring/samples/UsingSockets/tcpserver.ring I get next error message:
--------------------------------------------------------------------------------------------------
Line 4 Bind Error
In bind() in file C:/Ring/samples/UsingSockets/tcpserver.ring
--------------------------------------------------------------------------------------------------
The code is:
------------------------------------------------------------------
load "sockets.ring"
sock = socket(AF_INET,SOCK_STREAM,0)
bind(sock,"127.0.0.1",5050)
listen(sock,5)
ns = accept(sock)
send(ns,"Hello Client")
msg = recv(ns,1024)
? "Client Say >> " + msg
close(ns)
close(sock)
? "Socket connection closed"
------------------------------------------------------------------
Have a nice day and good work.
Greetings,
Gal Zsolt

Hello Gal,
if you get bind error, that means some other process uses socket 5050 or it is blocked by firewall (it will not be reported unless your configuration says so).
Check if you have running ring process which wasn't stopped correctly and still uses socket 5050 or use netstat -a (dos prompt) command to find all occupied ports.

Hello Ilir,
Thanks for your useful suggestions, I try to do them.

Hello Ilir,
I use port not occupied, but the program still does not work properly.

Hello Gal,
change the port in Ring source to 8081. This port (including 8080) is usually used by proxy servers, other Ring samples use them without a problem. Something is blocking port 5050 on your machine, I can't know what without physical access to your machine.

Hello Ilir,
I changed the port to 8081 but still get same error message.

Hello Gal,
what happens if you run samples\webserver\ringlibuv\webserver.ring?

Hello Gal,
as the message says:
Listen error address already in use. Something is running on your machine using all ports you tried. What netstat -a says about ports 5050,8080,8081? Can you run task manager, performance, open resource monitor, network to see which processes are using above ports?

Hello Gal,
as you can see, ports 5050,8080,8081 are used. Use resource monitor to check which process occupies which port and shut it down. Or simply restart your computer and see what will happen.

Hello Ilir,
I restarted the computer and still got same error.
How can I use resource monitor?
