SFTP silent login
Hi,
I am connecting via SFTP to a remote Server. My problem is on trying to LOGin, I am asked for a password. I need to make this process automatic such that I can login without being prompted for a password.
I can achieve this if the remote server has a simple FTP server and not SFTP. How can I achieve this for SFTP ???
I have heard about some solution using KERBEROS but it appears way too complicated and even our System and Network Admins dont have any idea on how to use it..
Appreciate any suggestions,
TIA,
sg

curlopt_filetime
CURLOPT_FILETIME(3) curl_easy_setopt options CURLOPT_FILETIME(3)
NAME
CURLOPT_FILETIME - get the modification time of the remote resource
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);
DESCRIPTION
Pass a long. If it is 1, libcurl will attempt to get the modification time of the remote document in this operation. This requires that the
remote server sends the time or replies to a time querying command. The curl_easy_getinfo(3) function with the CURLINFO_FILETIME(3) argu-
ment can be used after a transfer to extract the received time (if any).
DEFAULT
0
PROTOCOLS
HTTP, FTP, SFTP, FILE
EXAMPLE
curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, url);
/* Ask for filetime */
curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
res = curl_easy_perform(curl);
if(CURLE_OK == res) {
res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
if((CURLE_OK == res) && (filetime >= 0)) {
time_t file_time = (time_t)filetime;
printf("filetime %s: %s", filename, ctime(&file_time));
}
}
/* always cleanup */
curl_easy_cleanup(curl);
}
AVAILABILITY
Always, for SFTP since 7.49.0
