無法打開遠程文件：SCP狀態代碼1D無效libssh 0.7.3

免責聲明：谷歌-fu'ing通過這個我的方式...無法打開遠程文件：SCP狀態代碼1D無效libssh 0.7.3

我想知道如果任何人都能夠去看看在這&指向我在正確的方向&謝謝你的任何人能夠解決......我剛剛從想法的新鮮...

與長度變量關聯的文件大小函數是這個;

ifstream::pos_type filesize(const char* filename) 
{ 
    ifstream in(filename, ios::binary | ios::ate); 
    return in.tellg(); 
}

我從這件作品中看到了「scp狀態碼1d無效」

rc = ssh_scp_push_file(scp, "samp_batch", length, 0766); 
if (rc != SSH_OK) 
{ 
    fprintf(stderr, "Can't open remote file: %s\n", ssh_get_error(my_ssh_session)); 
    ssh_free(my_ssh_session); 
    exit(-1); 
}

該功能;

int ssh() 
{ 
    ssh_session my_ssh_session; 
    ssh_scp scp; 
    int port = 22; 
    int rc; 
    int method; 
    const long int length = filesize("samp_batch"); 
    char password[128] = { 0 }; 
    my_ssh_session = ssh_new(); 
    if (my_ssh_session == NULL) 
     exit(-1); 
    ssh_options_set(my_ssh_session, SSH_OPTIONS_HOST, "10.52.136.185"); 
    ssh_options_set(my_ssh_session, SSH_OPTIONS_PORT, &port); 
    ssh_options_set(my_ssh_session, SSH_OPTIONS_USER, "security"); 

    //connect to server 
    rc = ssh_connect(my_ssh_session); 
    if (rc != SSH_OK) 
    { 
     fprintf(stderr, "Error connecting to host: %s\n", ssh_get_error(my_ssh_session)); 
     ssh_free(my_ssh_session); 
     exit(-1); 
    } 

    //verify the servers identity 
    if (verify_knownHost(my_ssh_session) < 0) 
    { 
     fprintf(stdout, "unkown host\n"); 
     ssh_disconnect(my_ssh_session); 
     ssh_free(my_ssh_session); 
     exit(-1); 
    } 


    // Try to authenticate 
    rc = ssh_userauth_none(my_ssh_session, NULL); 
    if (rc == SSH_AUTH_ERROR) { 
     error(my_ssh_session); 
     return rc; 
    } 

    method = ssh_auth_list(my_ssh_session); 
    while (rc != SSH_AUTH_SUCCESS) { 
     // Try to authenticate with public key first 
     if (method & SSH_AUTH_METHOD_PUBLICKEY) { 
      rc = ssh_userauth_autopubkey(my_ssh_session, NULL); 
      if (rc == SSH_AUTH_ERROR) { 
       error(my_ssh_session); 
       return rc; 
      } 
      else if (rc == SSH_AUTH_SUCCESS) { 
       break; 
      } 
     } 

     // Try to authenticate with keyboard interactive"; 
     if (method & SSH_AUTH_METHOD_INTERACTIVE) { 
      rc = authenticate_kbdint(my_ssh_session, NULL); 
      if (rc == SSH_AUTH_ERROR) { 
       error(my_ssh_session); 
       return rc; 
      } 
      else if (rc == SSH_AUTH_SUCCESS) { 
       break; 
      } 
     } 

     if (ssh_getpass("Password: ", password, sizeof(password), 0, 0) < 0) { 
      return SSH_AUTH_ERROR; 
     } 

     // Try to authenticate with password 
     if (method & SSH_AUTH_METHOD_PASSWORD) { 
      rc = ssh_userauth_password(my_ssh_session, NULL, password); 
      if (rc == SSH_AUTH_ERROR) { 
       error(my_ssh_session); 
       return rc; 
      } 
      else if (rc == SSH_AUTH_SUCCESS) { 
       break; 
      } 
     } 
    } 

    //SCP samp_batch file here 
    scp = ssh_scp_new(my_ssh_session, SSH_SCP_WRITE, "/"); 
    if (scp == NULL) 
    { 
     fprintf(stderr, "Error allocating scp session: %s\n", ssh_get_error(my_ssh_session)); 
     return SSH_ERROR; 
    } 
    rc = ssh_scp_init(scp); 
    if (rc != SSH_OK) 
    { 
     fprintf(stderr, "Error initializing scp session: %s\n", ssh_get_error(my_ssh_session)); 
     ssh_scp_free(scp); 
     return rc; 
    } 

    rc = ssh_scp_push_file(scp, "samp_batch", length, 0766); 
    if (rc != SSH_OK) 
    { 
     fprintf(stderr, "Can't open remote file: %s\n", ssh_get_error(my_ssh_session)); 
     ssh_free(my_ssh_session); 
     exit(-1); 
    } 

    const char *contents = "samp_batch"; 
    rc = ssh_scp_write(scp, contents, length); 
    if (rc != SSH_OK) 
    { 
     fprintf(stderr, "Cant write to remote file: %s\n", ssh_get_error(my_ssh_session)); 
     ssh_free(my_ssh_session); 
     exit(-1); 
    } 

    ssh_scp_close(scp); 
    ssh_scp_free(scp); 
    return SSH_OK; 

    //execute remote command here 


    ssh_free(my_ssh_session); 
    return 0; 
}

再說一次，任何見解都會很棒。我什至不能找到任何解釋什麼狀態代碼1d意味着：/

嘗試運行'ssh user @ remotehost echo foo'使用您用於此過程的相同用戶和主機。除了遠程服務器上的「foo」之外，還有其他的東西嗎？特別是，你會得到一個歡迎橫幅或類似的東西嗎？另外，您是否可以通過交互式運行'scp'實用程序來複制此文件？ – Kenster

@Kenster對於「ssh user @ remotehost echo foo」，[foo]是唯一返回的內容，沒有橫幅等，它是一個已知的主機，共享的pub文件。對於scp，[scp samp_batch user @ remotehost：/ home/user/samp_batch像魅力一樣工作 – Snow

@Kenster [ssh_scp_new（session，ssh_scp_write，「filepath」）;是不同的！它實際上是在遠端創建一個文件：D。（我現在也遇到了分段錯誤，但我明天就會開始工作）。謝謝您的幫助。 – Snow

scp = ssh_scp_new(my_ssh_session, SSH_SCP_WRITE, "/"); 
if (scp == NULL) 
{ 
    fprintf(stderr, "Error allocating scp session: %s\n", ssh_get_error(my_ssh_session)); 
    return SSH_ERROR; 
}

應該已經;

scp = ssh_scp_new(my_ssh_session, SSH_SCP_WRITE, "/home/user/"); 
if (scp == NULL) 
{ 
    fprintf(stderr, "Error allocating scp session: %s\n", ssh_get_error(my_ssh_session)); 
    return SSH_ERROR; 
}
