 I want to compile a little c program under Freebsd, but the source
 warns:
  
 "Linux 2.0.33 source, will compile on BSD if you modify the ip  
 header etc."

 I thought small tcp/ip applications could be copmiled under any Unix 
 :(,
 Well what should I modify? What's the difference between BSD ip 
 header and Linux ip header?
 
 the source:
 ...
 struct  iphdr *iph=(struct iphdr *)buf;
 struct  udphdr *udp=(struct udphdr *)(buf + 20);
 ...
 iph->version=4;
 iph->ihl=5;
 iph->tos=0;
 iph->tot_len=htons(sizeof(buf));
 iph->id=htons(1234);
 iph->frag_off=0;
 iph->ttl=255;
 iph->protocol=17;
 
 iph->saddr=inet_addr(SIP);
 iph->daddr=resolve_address(argv[1]);
   
 Should I modify udp header as well?
   
 Sincerely,
 
 Vlad Safronov
