[VSCODE] SFTP Config Error

SFTP 연결시 아래와 같은 오류 발생

> handshake failed no matching key exchange algorithm

 

검색 결과 SFTP Config에서 remote algorithms을 설정해줘야 하는것 같음

> 자세한 오류사항은 별도로 찾아보아야함

 

 

해당 서버에서 어떤 algorithms과 Server -> cipher 을 사용하는지는 vscode sftp에서 [debug]로 표시되길래

해당 부분 복사 붙여넣기 해봤더니 접속이 잘 됨

# algorithms

[08-23 12:09:20] [debug] (local) KEX algorithms: ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1
[08-23 12:09:20] [debug] (remote) KEX algorithms: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
[08-23 12:09:20] [debug] DEBUG: No matching key exchange algorithm


# ciphers

[08-23 12:09:38] [debug] (local) Client->Server ciphers: aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm,aes128-gcm@openssh.com,aes256-gcm,aes256-gcm@openssh.com
[08-23 12:09:38] [debug] (remote) Client->Server ciphers: aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc,rijndael-cbc@lysator.liu.se
[08-23 12:09:38] [debug] DEBUG: No matching Client->Server cipher

로컬에서 사용되는 algorithms과 ciphers가 remote와 다름에서 발생하는 오류로 추측됨

 

 

그리하여 기존 SFTP 설정에서 아래와 같이 추가

"algorithms": {
    "kex": [
      "diffie-hellman-group-exchange-sha1",
      "diffie-hellman-group1-sha1"
    ],
    "cipher": [
      "aes128-cbc",
      "3des-cbc",
      "blowfish-cbc",
      "cast128-cbc",
      "arcfour",
      "aes192-cbc",
      "aes256-cbc"
    ]
  }

 

오류 해결됨
