Security: April 2016 Archives

ssh/sftp 遇到 no matching cipher found 原因是在 OpenSSH 6.7 之後,
預設移除了不安全的 Cipher, *cbc 及 arcfour*
若使用較舊的 Client, 跟 Server 沒有 matching cipher 就會無法連線

更新 Client 或啟用 Server 端不安全的 Cipher,
在 sshd_config 加入 *cbc 的支援
Ciphers 3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,,,blowfish-cbc,cast128-cbc,
若還是不行, 就全加, 在 sshd_config 加入 *cbc 及 arcfour* 的支援
Ciphers 3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,,,arcfour,arcfour128,
