Solution:
Onepossiblereasonisthatbecausethesshserverdaemon,orsshd,
isnotloadedandrunningonlocalhost,soanyattempttosshconnect
tolocalhostwouldfail.Ichecktoseewhethersshandsshdarerunning
bytypingthefollowingcommand:

$psaux|grepssh

#Result:bunchoflines,butnoneofthemisabout"sshd",onlyonelineisabout"ssh"

Resultis,Ionlyseesshrunning,butnotsshd.SoIknowsshserverdaemonisprobablynotstartedyet.
First,IverifythatIhaveinstalledthepackage“openssh-server”onmyfedorabox.
ThenIcheckthestatusofsshdservice:

YoumaynothaveOpenSSHcompletelyinstalled.Typethisinterminal:


sudoapt-getinstallopenssh-client

sudoapt-getinstallopenssh-server

Anotherproblemthatyoucouldhaveisthatyourfirewallcouldbe
blockingthesshconnection.IuseFirewallConfigurationtomanagemy
portsandfirewall.
