Replicação de Servidores [RESOLVIDO]

Como faço para verificar? Mas pelo visto o firewall esta ativo,como fazer para desativar?

/etc/init.d/iptables status

Se estiver rodando para ele ou libere a porta 22, mais por defualt o iptables não bloqueia a porta 22........


ve se o sshd está rodando

Pronto, sobre o firewall foi corrigido, mas está dando o seguinte erro:

root@172.29.0.181's password:
Permission denied,please try agayn

Está dando permissão negada, mas to fazendo isso como administrador, como faço para resolver essa situação. Que senha é essa,usuário da máquina??

Boa tarde srs,

Apagando a primeira linha do arquivo "/root/.ssh/known_hosts".

# sed -i 1d /root/.ssh/known_hosts 

ou

# ssh-keygen -f "/root/.ssh/known_hosts" -R 172.29.0.181 

Após apagar a linha tente novamente.

Boa noite, fiz o processo conforme a sua orientação, mas deu o seguinte erro:

Oi bom dia,

Por favor me ajuda nesse processo por favor.

Bom dia srs,

Realizei a configuração nos PostgreSQL, máquina servidor e escravo,mas quando eu vou fazer o rsync -av 172.29.0.2://var/lib/postgres/9.1/main ele pede a senha do root@172.29.0.2, gostaria de saber que senha é essa, o comando acima estou fazendo na maquina servidor.

Bom dia Srs,

Estou apenas com esse problema:

The PostgreSQL server failed to start. Please check the log output:
2014-04-12 08:48:52 BRT FATAL: could not load server certificate file "server.crt": Permissão negada
