You can then
1) edit your /root/.ssh/known_hosts
2) remove the line refering to the host you are trying to reach (fcbs01b)
(you can make copy of the known_hosts file in *.old or whatever at first if you don't feel confortable with deleting the line without having a copy)
3) connect again ssh root@fcbs01b
4) answer "yes" when prompted. (the corresponding host key will be regenerated in your /root/.ssh/known_hosts)
5) you should be connected now

NAME
sss_ssh_knownhostsproxy - get OpenSSH host keys
SYNOPSIS
sss_ssh_knownhostsproxy [options] HOST [PROXY_COMMAND]
DESCRIPTION
sss_ssh_knownhostsproxy acquires SSH host public keys for host HOST, stores them in a custom OpenSSH known_hosts file (see the
"SSH_KNOWN_HOSTS FILE FORMAT" section of sshd(8) for more information) /var/lib/sss/pubconf/known_hosts and estabilishes connection to the
host.
If PROXY_COMMAND is specified, it is used to create the connection to the host instead of opening a socket.
ssh(1) can be configured to use sss_ssh_knownhostsproxy for host key authentication by using the following directives for ssh(1)
configuration:
ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h
GlobalKnownHostsFile2 /var/lib/sss/pubconf/known_hosts
This is an experimental feature, please use http://fedorahosted.org/sssd to report any issues.
OPTIONS
-p,--port PORT
Use port PORT to connect to the host. By default, port 22 is used.
-d,--domain DOMAIN
Search for host public keys in SSSD domain DOMAIN.
-h,--help
Display help message and exit.
