libzt
Library version of ZeroTier
libzt makes it easy to securely connect devices, servers, cloud VMs, containers, and apps everywhere and manage them at scale. We provide a socket-like API supporting SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW. There's no need for system-wide virtual interfaces. This connection is exclusive to your app and fully encrypted via the Salsa20 cipher. For a more in-depth discussion on the technical side of ZeroTier, check out our Manual
C++ Example
#include <sys/socket.h>
#include <arpa/inet.h>
#include <netinet/in.h>
#include "libzt.h"
int main()
{
char *str = "welcome to the machine";
char *remoteIp = "10.8.8.42";
int remotePort = 8080;
int fd, err = 0;
struct sockaddr_in addr;
addr.sin_family = AF_INET;
addr.sin_addr.s_addr = inet_addr(remoteIp);
addr.sin_port = htons(remotePort);
zts_startjoin("path", 0xc7cd7c981b0f52a2); // config path, network ID
if ((fd = zts_socket(AF_INET, SOCK_STREAM, 0)) < 0) {
printf("error creating socket\n");
}
if ((err = zts_connect(fd, (const struct sockaddr *)&addr, sizeof(addr))) < 0) {
printf("error connecting to remote host\n");
}
if ((err = zts_write(fd, str, strlen(str))) < 0) {
printf("error writing to socket\n");
}
zts_close(fd);
zts_stop();
return 0;
}
