Colegas, estou tentando fazer um ssh de uma máquina qualquer para o meu servidor que eu chamo de nxserver, mas quando eu vou dar um ssh, ele me retorna este erro:
ssh_exchange_identification: Connection closed by remote host

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
