We have a customer SFTP client that experiences this error " SocketError: WSAECONNRESET An existing connection was forcibly closed by the remote host." they are running the SFTP process inside MS SQL Server (SSIS). I have examined our server side log and do not see the server sending a disconnect to the client. So I am guessing that a router/firewall in between is terminating the socket. Can that be the case? They are actively downloading data but this error always pop up around after 10 minutes of data transfer when a rekey is happening On our server, we have a barebone configuration. We do not have SFTPClientAlive defined. Will it help of SFTPClientAlive is set? thanks -------------- Client Error logs -------------- Received SSH2_MSG_KEXINITrekeyStart: build_kexInit: preferRsaHostKeyAlgorithm: 1 (leaveContext) KeyExchangeAlgs: algorithm: ecdh-sha2-nistp521 algorithm: ecdh-sha2-nistp384 algorithm: ecdh-sha2-nistp256 algorithm: diffie-hellman-group18-sha512 algorithm: diffie-hellman-group16-sha512 algorithm: diffie-hellman-group14-sha256 algorithm: diffie-hellman-group-exchange-sha256 algorithm: diffie-hellman-group-exchange-sha1 algorithm: diffie-hellman-group14-sha1 algorithm: rsa1024-sha1 (leaveContext) HostKeyAlgs: algorithm: ssh-rsa (leaveContext) EncCS: algorithm: aes256-ctr algorithm: aes192-ctr algorithm: aes128-ctr algorithm: aes256-cbc algorithm: aes192-cbc algorithm: aes128-cbc algorithm: blowfish-ctr algorithm: blowfish-cbc algorithm: cast128-cbc algorithm: arcfour256 algorithm: arcfour128 algorithm: 3des-ctr algorithm: 3des-cbc (leaveContext 15ms) EncSC: algorithm: aes256-ctr algorithm: aes192-ctr algorithm: aes128-ctr algorithm: aes256-cbc algorithm: aes192-cbc algorithm: aes128-cbc algorithm: blowfish-ctr algorithm: blowfish-cbc algorithm: cast128-cbc algorithm: arcfour256 algorithm: arcfour128 algorithm: 3des-ctr algorithm: 3des-cbc (leaveContext) MacCS: algorithm: hmac-sha2-256 algorithm: hmac-sha2-512 algorithm: hmac-sha1 algorithm: hmac-sha1-96 algorithm: hmac-md5 algorithm: hmac-md5-96 algorithm: hmac-ripemd160 algorithm: [email protected] algorithm: [email protected] (leaveContext) MacSC: algorithm: hmac-sha2-256 algorithm: hmac-sha2-512 algorithm: hmac-sha1 algorithm: hmac-sha1-96 algorithm: hmac-md5 algorithm: hmac-md5-96 algorithm: hmac-ripemd160 algorithm: [email protected] algorithm: [email protected] (leaveContext) CompCS: algorithm: [email protected] algorithm: zlib algorithm: none (leaveContext) CompSC: algorithm: [email protected] algorithm: zlib algorithm: none (leaveContext) LangCS: (leaveContext) LangSC: (leaveContext) ChosenIncomingEncryption: aes128-ctr ChosenOutgoingEncryptoin: aes128-ctr ChosenIncomingMac: hmac-sha1 ChosenOutgoingMac: hmac-sha1 ChosenIncomingCompression: none ChosenOutgoingCompression: none ChosenKexAlgorithm: ecdh-sha2-nistp256 choose_hostkey_algorithm: (leaveContext) ChosenHostKeyAlgorithm: ssh-rsa numBits: 128 pbits: 1024 m_keyAlg: 1256 Using ECDH. sendEcDhInit: initCrypt_aes2: (leaveContext) getEntropy: (leaveContext) fortunaAddEntropy: (leaveContext) fortunaReseed: initCrypt_aes2: (leaveContext) (leaveContext) generateNewKey_ecc: loadCurveByName: name: secp256r1 (leaveContext) initCrypt_aes2: (leaveContext) pointMultiply: (leaveContext) (leaveContext) exportEccPoint: (leaveContext) Error sending on socket (1) SocketError: WSAECONNRESET An existing connection was forcibly closed by the remote host.
