Hello,
I created account scom-user on my test Linux Ubuntu server, added account to 3 profiles, installed openSSH, added group scom-user to /etc/ssh/sshd_config, restarted SSH service, added 22 port and others to iptables, tried to telnet 22 port and connect to server from SCOM server using Putty successfully, but discovery does not work with error "SSH connection error" (exit code-1073479115).
