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 putty network error connection refused raspberry pi 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.

We do not attempt to list all error messages here: there are many which should never occur, and some which should be self-explanatory. If you get an https://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter10.html error message which is not listed in this chapter and which you don't understand, report it to us as a bug (see appendix B) and we will add documentation for it. 10.1 ‘The server's host key is not cached in the registry' This error message occurs when PuTTY connects to a new SSH server. Every server identifies itself by means of a host key; once PuTTY knows the host key for a server, it will be able to detect if a malicious attacker redirects your connection to another machine. If you see this message, it means that PuTTY has not seen this host key before, and has no way of knowing whether it is correct or not. You should attempt to verify the host key by other means, such as asking the machine's administrator. If you see this message and you know that your installation of PuTTY has connected to the same server before, it may have been recently upgraded to SSH protocol version 2. SSH protocols 1 and 2 use separate host keys, so when you first use SSH-2 with a server you have only used SSH-1 with before, you will see this message again. You should verify the correctness of the key as before. See section 2.2 for more information o

I had PuTTY up & running untill I did a reinstall of Fedora13. I can ping 192.168.1.163 fine. SELinux is disabled. Firewall is default (SSH allowed on p22). I have just disabled the firewall with same result) PuTTY reports: =~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2010.07.20 16:23:52 putty network error =~=~=~=~=~=~=~=~=~=~=~= Event Log: Writing new session log (SSH raw data mode) to file: C:\Users\wim\Desktop\putty.log Event Log: Looking up host "192.168.1.163" Event Log: Connecting to 192.168.1.163 port 22 Event Log: Failed to connect to 192.168.1.163: Network error: Connection timed out Event Log: Network error: Connection timed out Does anyone have a clue? To confuse the matters (as I can Ping 192.168.1.163 normally) see below. Any input greatly appreciated. this THREAD seems to have a short and a longer version (5 replies). It is solved. However I can't seem to edit the correct thread. Solution was given by Scot35276: sshd was not running. Thankyou Scott.

Another possibility is that the firewall is blocking access (check the "trusted services" list). jpollard View Public Profile Find all posts by jpollard #3 28th July 2010, 03:19 PM scott32746 Offline Registered User Join Date: Jun 2007 Location: Lake Mary, Florida Age: 52 Posts: 1,088 Re: Pink OK but PuTTY gets connecti

Understanding the cause of the message will ultimately lead you to solving your problem. The message 'Connection Refused' has two main causes: Nothing is listening on the IP:Port you are trying to connect to. The port is blocked by a firewall. No process is listening. This is by far the most common reason for the message. To determine if this is the problem, on the remote system run netstat or ss1 e.g. if you are expecting a process to be listening on port 22222 sudo netstat -tnlp | grep :22222 or ss -tnlp | grep :22222 For OSX a suitable command is sudo netstat -tnlp tcp | grep '\.80 ' If nothing is listening then the above will produce no output. If you see some output then confirm that it's what you expect then see the firewall section below. If you don't have access to the remote system and want to confirm the problem before reporting it to the relevant administrators you can use tcpdump (wireshark or similar). When a connection is attempted to an IP:port where nothing is listening, the response from the remote system to the initial SYN packet is a packet with the flags RST,ACK set. This closes the connection and causes the Connection Refused message e.g. $ sudo tc
