Estou tentando fazer login em uma máquina remota com SSH ou SFTP.
- quando tento
ssh [email protected]
, a CLI simplesmente não responde. Eu recebo uma nova linha vazia, na qual eu posso digitar caracteres, mas nada mais.
- quando tento me conectar com
SFTP
usando as mesmas credenciais (uso Transmit
como meu cliente SFTP) ele fica pendurado para sempre e não se conecta.
Sem erros. Sem resposta.
O problema não é específico de frbit.com
e persiste com qualquer outro servidor que eu tente conectar.
depuração do cliente ssh
Executando o cliente ssh com o sinalizador -vv, obtive a seguinte saída:

depuração do ssh-agent
UPDATE: passando pelo meu local (máquina do cliente ssh) system.log
encontrei o seguinte:
Mar 6 10:28:17 matanyas-imac com.apple.launchd.peruser.501[235] (org.openbsd.ssh-agent[574]): Exited with code: 1
Mar 6 10:28:17 matanyas-imac com.apple.launchd.peruser.501[235] (org.openbsd.ssh-agent): Throttling respawn: Will start in 10 seconds
Mar 6 10:28:27 matanyas-imac com.apple.launchd.peruser.501[235] (org.openbsd.ssh-agent[575]): Exited with code: 1
Mar 6 10:28:27 matanyas-imac com.apple.launchd.peruser.501[235] (org.openbsd.ssh-agent): Throttling respawn: Will start in 10 seconds
O que significa Code 1
?
UPDATE: encontrei o arquivo com o qual launchd
tem problemas em System/Library/LaunchAgents/org.openbsd.ssh-agent.plist
:
<?xml version="1.0" encoding="UTF-8"?>

Quando executo /usr/bin/ssh-agent
, obtenho:
SSH_AUTH_SOCK=/var/folders/pg/1g6_hnwx47bgqv5vcm1lq18h0000gn/T//ssh-01WuaHF32SlV/agent.2145; export SSH_AUTH_SOCK;
SSH_AGENT_PID=2146; export SSH_AGENT_PID;
echo Agent pid 2146;
como para o -l
flag ( <string>-l</string>
), não existe esse flag na minha versão de ssh-agent
. Saídas:
ssh-agent: illegal option -- l
ps aux | grep

Versão SSH: OpenSSH_5.8p2, OpenSSL 0.9.8r 8 de fevereiro de 2011
ATUALIZAÇÃO: Descobri que não importa com qual usuário eu inicialmente faço login na inicialização do sistema - seja meu ou da raiz - ssh não funcionará até que eu seja explicitamente alternar usuário no terminal ( su -
ou su matanya
)
ATUALIZAÇÃO:
Eu verifiquei as assinaturas de código.
Ran: codesign -vv /usr/bin/ssh-agent
:
recebido:
/usr/bin/ssh-agent: code object is not signed at all
In architecture: x86_64
Deve ser:
/usr/bin/ssh-agent: valid on disk
/usr/bin/ssh-agent: satisfies its Designated Requirement
ATUALIZAÇÃO:
Quando executo :
eval 'ssh-agent'
ssh-add
Eu consigo entrar com o ssh.
