I was trying to setup sublime text editor to connect via sftp on my server but was getting connection timeout all the time. I found a solution and followed this article : https://superuser.com/a/957666

They suggested to change the server config to accept a mac algorithm used by the client by adding this hmac-sha1 on KexAlgorithms. So in /etc/ssh/sshd_config, I changed:

KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1

to

KexAlgorithms diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,hmac-sha1

And now i try to login on my server and i get Network error: Connection refused

How can i regain access to my server? My server is hosted on kimsufy.

  • if you're trying to troubleshoot ssh why not do it normally i.e. not with sublime.. then add sublime if you have it working normally. And can you show a screenshot of sftp in sublime, it sounds interesting. – barlop Oct 2 '15 at 9:06

Network error: Connection refused means that the server refused to open the connection (at the TCP level). The usual cause is that sshd is not running.

I think sshd does not like something in the configuration and aborts. Look in the sshd log.

By the way hmac-sha1 does not seems to be a valid value for KexAlgorithms but for MACs
