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?
...
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
