i tried login ssh to my vps server with ip 1.1.1.1 from santrex hosting
but i always got error messages “server unexpectedly closed network connection”
for the first time i try login with lvm webpannel
adn can login ssh with loginvm@91.1.1.1
then i generated 3 key of sshd:
ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_key -N “”
ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N “”
ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N “”
