hi, I'm using: libcurl (7.21.3) + openssl(0.9.8k) + libssh2(1.2.8) as SFTP client to try to download 1 byte from server . Client side code is like this:
CURL *curl = curl_easy_init(); curl_easy_setopt(curl, CURLOPT_SSH_AUTH_TYPES, CURLSSH_AUTH_PASSWORD); curl_easy_setopt(curl, CURLOPT_USERPWD, m_userpwd.c_str()); curl_easy_setopt(curl, CURLOPT_URL, myUrl.c_str()); curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); curl_easy_setopt(curl, CURLOPT_WRITEDATA, hd_src); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, this->write_callback); curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)1); curl_easy_perform(curl); curl_easy_cleanup(curl); To most SFTP server, this works fine. But when we use this code to connect to the SFTP server that our customer provided. We get this error in step curl_easy_perform(curl) : But if we try to connect customer's SFTP server by FileZilla or other mature SFTP client, no error occur. This seems to be really serious issue, and I don't know what is wrong here. Please do help to figure it out. Thanks.
