este é o meu primeiro socorro aqui, apesar de ser um leitor diário para aprender.
Estou trabalhando em um ambiente Unix (servidores Solaris e Aix) e minha chave pública de repente parou de funcionar depois de meses. Tentei recriar a chave, mas ela ainda não está funcionando, aqui estão os passos que realizei:
cd
cd .ssh
ssh-keygen -t dsa (input nothing on 3 prompts just as did before)
cat id_dsa.pub > authorized_keys
Depois disso, enviei todos os arquivos para ~ / .ssh no servidor desejado e confirmei que estava lá. E isso não funcionou.
Eu fiz uma pesquisa de defeitos e: 1. As permissões estão bem: o diretório .ssh é 700; chaves autorizadas é 600 (eu tentei com muitas permissões). 2. O sshd_config tem apenas estas entradas:
ListenAddress 0.0.0.0
Protocol 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
SyslogFacility AUTH
LogLevel INFO
PermitRootLogin yes
PrintMotd yes
PidFile /etc/ssh/sshd.pid
Banner /etc/issue
Subsystem sftp /usr/sbin/sftp-server
Eu tentei recriar essas chaves várias vezes ... Além disso, tentei criar uma chave RSA e authorized_keys2, nenhuma funcionou. O curioso é que estava trabalhando antes com essas mesmas configurações. Serviços SSH como outras ferramentas Unix são administrados por um Administrador do Sistema neste ambiente. Aqui está minha saída ssh -vv para que você possa me ajudar:

O que eu preciso é fazer o login nos servidores sem que seja solicitada a senha.
