But connect() depends on a specific IP and port being ready for use. –Remy Lebeau May 21 '15 at 19:02 Server Fault has a canonical question about Connection Refused. –Raedwald Sep 30 '15 at 12:34 add a comment| 9 Answers 9 active oldest votes up vote 40 down vote accepted There could be many reasons, but the most common are: The port is not open on the destination machine. The port is open on the destination machine, but its backlog of pending connections is full. A firewall between the client and server is blocking access (also check local firewalls). After checking for firewalls and that the port is open, use telnet to connect to the ip/port to test connectivity. This removes any potential issues from your application. share|improve this answer edited May 21 '15 at 18:55 Remy Lebeau 231k13141269 answered Feb 25 '10 at 11:02 a'r 20.5k33755 3 Firewalls would normally give timeout errors, as the connect (SYN) packet is just discarded. Connection refused is because the server has received and rejected the SYN packet. –CuriousPanda Feb 25 '10 at 11:04

This Site Careers Other all forums Forum: Sockets and Internet Protocols Connection refused, Socket Help Benjamin Rohrer Greenhorn Posts: 7 posted 5 years ago I apologize in advance if this has already been asked, im sure it https://coderanch.com/t/540638/sockets/java/Connection-refused-Socket has. But I've been searching and cant get any answers. I'm learning how to http://askubuntu.com/questions/30080/how-to-solve-connection-refused-errors-in-ssh-connection make simple Client/Server Connections using Sockets and ServerSockets. I started out with a client and a server both running on the same machine, the IP address the client was using was the local "127.0.0.1" loopback address. However, when I ran the server from my desktop, and the client from my laptop , it did not connection refused work. The first time I used my external IP address and I received a connection timed out error. So I changed the IP address in the client to the internal "192. etc." and this time received a connection refused error. I do have a firewall, however i've changed the settings on both machines to allow connections from the appropriate java programs. I'm starting to think that my problem may error connecting to be my router? As in, i need to change a setting in my router to allow the connection, but I honestly have no idea. If i need to post the code i will, its very short. But i think I may just have a problem with the addresses. Let me know. Thanks in advance. Ben Marco Ehrentreich best scout Bartender Posts: 1294 I like... posted 5 years ago Hi Benjamin, the reason for timeout errors is most probably your firewall silently dropping packets. It's hard to tell what exactly is the problem without knowing more about your firewall and network setup. A connection refused error usually means that the server socket (protocol+IP+port) is not opened and listening for incoming connections. On Windows and UNIX/Linux you can use the "netstat" utility to check for open sockets. If there's no socket in listening mode for the address your client tries to connect to the problem is on the server side. If that's not the case the problem could indeed be your router/firewall. But here again it's hard give better advices without having more details. Marco P.S: Welcome to JavaRanch Benjamin Rohrer Greenhorn Posts: 7 posted 5 years ago Thanks Marco. I appreciate it. I

I'm making SSH connections to it from my PC via Putty. The problem is, sometimes I'm able to login seamlessly. However, sometimes it gives me an error like this: Network error: Connection refused. Then, I dont't change anything, try to login a few times more, wait a while and try again. Sometimes I can log in, sometimes I cannot. It seems pretty random to me. What can I do to solve this? Edit: And Sometimes, Putty gives Network error: Software caused connection abort error after displaying login as: text.
