Re: 'Short sftp packet error' in libssh

Following the last email I don't see any options to change chunk size when copying a file to the remote computer:

#include <libssh/sftp.h>
#include <sys/stat.h>
#include <fcntl.h>
int sftp_helloworld(ssh_session session, sftp_session sftp)
int access_type = O_WRONLY | O_CREAT | O_TRUNC;
sftp_file file;
const char *helloworld = "Hello, World!\n";
int length = strlen(helloworld);
int rc, nwritten;
file = sftp_open(sftp, "helloworld/helloworld.txt",
access_type, S_IRWXU);
if (file == NULL)
fprintf(stderr, "Can't open file for writing: %s\n",
return SSH_ERROR;
nwritten = sftp_write(file, helloworld, length);
if (nwritten != length)
fprintf(stderr, "Can't write data to file: %s\n",
return SSH_ERROR;
rc = sftp_close(file);
if (rc != SSH_OK)
fprintf(stderr, "Can't close the written file: %s\n",
return rc;
return SSH_OK;

I dont know. How can I check it?

I am using the exact same sample code provided in the documentation.

I am sending a file from x86-64 system to ARM system.

do you write in 16k chunks?
