#PUTTY SSH CONNECTION REFUSED SOFTWARE#
You can also try some software that tests the uptime of an Internet connection. See: Internet Connectivity Monitor. If you see even one message saying “Request timed out”, this indicates an internet connectivity issue, which may cause PuTTY to disconnect with “Network Error: Software Caused Connection Abort”. Open Windows Command Prompt and run ping -t (or the IP address of your remote server) and leave it running while your SSH connection is open. Monitoring your pings is a good way of determining if your internet connection is dropping packets and to blame for PuTTY disconnecting. If you are still getting the error “Network Error: Software Caused Connection Abort” despite enabling TCP Keepalives, the problem may be due to an unreliable Internet connection. Still Getting Disconnected? Check for an unreliable Internet connection If you are using a PuTTY session profile, don’t forget to Save your profile with these new settings. Now click Open and leave the SSH connection idle for a while to see if it stays up. In the field beside Seconds between keepalives, enter 5.Ĭheck Enable TCP Keepalives (SO_KEEPALIVE option) In the left-hand menu pane, select Connection To solve this issue, you can configure PuTTY to send null packets and TCP keepalives every few seconds. This can cause PuTTY sessions to be unexpectedly closed by the firewall if no traffic is seen in the session for some time, which will trigger the error: “Network Error: Software Caused Connection Abort”. Usually, these firewalls will assume a connection is dead if no data is transferred in either direction after a certain time interval.
Some network routers and firewalls need to keep track of all connections through them.
