Trying to do a ksh script that needs to list all ip address between ip address a and b ..
ie.
Ip address A=192.168.1.200
Ip address B=192.168.2.15
So the subnet changes from 1 to 2 but I want to list all possible ip addresses between the 2..
Which would be:
192.168.1.200... (4 Replies)

four interfaces with ifconfig
all interfaces have the same mac. If is not set for unique.
but it still works.
what difference does it make to have all macs the same or different? (4 Replies)

pcap_compile
PCAP_COMPILE(3PCAP)PCAP_COMPILE(3PCAP)NAME
pcap_compile - compile a filter expression
SYNOPSIS
#include <pcap/pcap.h>
int pcap_compile(pcap_t *p, struct bpf_program *fp,
const char *str, int optimize, bpf_u_int32 netmask);
DESCRIPTION
pcap_compile() is used to compile the string str into a filter program. See pcap-filter(7) for the syntax of that string. program is a
pointer to a bpf_program struct and is filled in by pcap_compile(). optimize controls whether optimization on the resulting code is per-
formed. netmask specifies the IPv4 netmask of the network on which packets are being captured; it is used only when checking for IPv4
broadcast addresses in the filter program. If the netmask of the network on which packets are being captured isn't known to the program,
or if packets are being captured on the Linux "any" pseudo-interface that can capture on more than one network, a value of PCAP_NET-
MASK_UNKNOWN can be supplied; tests for IPv4 broadcast addresses will fail to compile, but all other tests in the filter program will be
OK.
RETURN VALUE
pcap_compile() returns 0 on success and -1 on failure. If -1 is returned, pcap_geterr() or pcap_perror() may be called with p as an argu-
ment to fetch or display the error text.
