Question

免责声明：Google-fu帮助我解决这个问题......

我想知道是否有人能够看看这个＆amp;指出我正确的方向＆amp;谢谢任何有能力解决的人......我再次出乎意料......

与长度变量关联的文件大小函数是this;

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

我抓住＆＃34; scp状态代码1d无效＆＃34;来自这篇文章;

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);
}

此功能;

int ssh()
{
    ssh_session my_ssh_session;
    ssh_scp scp;
    int port = 22;
    int rc;
    int method;
    const long int length = filesize("samp_batch");

    //execute remote command here


    ssh_free(my_ssh_session);

同样，任何见解都会很棒。我甚至找不到任何解释状态代码1d的含义：/

Answer 1

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;
}

应该是;

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;
}

无法打开远程文件：SCP状态代码1d无效libssh 0.7.3
