Yesterday I upgraded one of my computers to Leap 15.4. Everything works fine except for problems with the network. When I try to connect to it from outside by ssh, it answers:
ssh: connect to host az port 22: Connection refused
At first I thought it was a firewall problem. So, I stopped firewalld and changed the start mode to "manual" in yast. But that did not help.
How can I allow connections from outside again?
Thank you in advance, Wolfgang
i am on tumbleweed and have had a vew month in past some problems copnnecting to a old server: if you connect to a old system, it might be that the key methode will not work any more your client offer. newer ssh has drop or disabled some of the old methodes. but my error message was a little different could also that the key is verry old and you have to generate new keys you could tell the ssh to use old key methode, but you should not do this if you go over internet...... some parts of my notes: according to :https://tools.ietf.org/id/draft-ietf-curdle-ssh-kex-sha2-09.html maybe use for older systems (best of the worse for very old systems): diffie-hellman-group14-sha1 (or for your case maybe a more weak is needed, or a better could be used) at to /etc/ssh/ssh_config 4 new lines: Host yourhostname KexAlgorithms +diffie-hellman-group14-sha1 Host your.host.ipv4.adress KexAlgorithms +diffie-hellman-group14-sha1 same/similar to this should work the oposite way, if you have a new host and try to connect from a old client. again if is this problem be sure you know what you do, otherwise you will drill a nice hole into your security...... better ist to update the ssh / sshd on both sides (if possible). simoN -- www.becherer.de
