Dobry den, hledal jsem na netu zpusob jak zjistit IP adresu pocitace, nasel jsem dva zpusoby, akorat ze pro Ubuntu to funguje, ale pro debian ne, nevim jestli mam spatne nainstalovany debian, nebo se musi kod nejak upravit.

script:

 #!/usr/bin/env python
import socket
hostname = socket.gethostname()
ip = socket.gethostbyname( socket.gethostname() )
print 'Hostname:', hostname
print 'IP adresa:', ip

 Ubuntu:

Hostname: Ubuntu8


IP Adresa: 127.0.1.1

 Debian:

Traceback (most recent call last):
  File "./h", line 5, in <module>
    ip = socket.gethostbyname( socket.gethostname() )
socket.gaierror: (-5, 'No address associated with hostname')
 

jiny zpusob

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <netdb.h>
#include <unistd.h>

#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int main(void)
{
      struct hostent *he;
      char buf[80];

      if(gethostname(buf,sizeof(buf))==-1) {
            perror("gethostname");
            exit(1);
      }
      printf("Host Name: %s\n", buf);
      
      if((he=gethostbyname(buf))==0) {
            herror("gethostbyname");
            exit(1);
      }
      printf("Your Host Name: %s\n", he->h_name);
      rintf("Your IP Address: %s\n", inet_ntoa(*((struct in_addr *)he->h_addr_list)));

      return 0;
}

 Ubuntu:

Host name: Ubuntu8


Your Host Name: Ubuntu8


Your IP Address: 127.0.1.1

 Debian:

Host Name: debian
gethostbyname: Unknown host
