#2 jnettop 0.7 and FreeBSD 5.0

[Anonymous]

Hello,

I have downloaded jnettop and am trying to get it running
on my FreeBSD
system but I'm not having much luck. After I
run ./configure I run make and
get the following errors:

zephyr:~/jnettop-0.7$ gmake
gmake all-am
gmake[1]: Entering directory `/usr/home/mpc/jnettop-0.7'

gmake[1]: *** [jnettop.o] Error 1
gmake[1]: Leaving directory `/usr/home/mpc/jnettop-0.7'
gmake: *** [all] Error 2

So what I did next was just comment out lines 219
through 224, which allows
it to compile, but when I try to run it with "jnettop -i eth0"
as root I get
the following error:

Not sniffing. Error while initializing eth0: BIOCSETIF:
eth0: Device not
configured

If I start it without the -i it segfaults.

This might be helpful - it is from /usr/include/net/if.h
/*
* Interface request structure used for socket
* ioctl's. All interface ioctl's must have parameter
* definitions which begin with ifr_name. The
* remainder may be interface specific.
*/
struct ifreq {
char ifr_name[IFNAMSIZ]; /* if name,
e.g. "en0" */
union {
struct sockaddr ifru_addr;
struct sockaddr ifru_dstaddr;
struct sockaddr ifru_broadaddr;
short ifru_flags[2];
short ifru_index;
int ifru_metric;
int ifru_mtu;
int ifru_phys;
int ifru_media;
caddr_t ifru_data;
int ifru_cap[2];
} ifr_ifru;
#define ifr_addr ifr_ifru.ifru_addr /* address */
#define ifr_dstaddr ifr_ifru.ifru_dstaddr /* other end of
p-to-p link
*/
#define ifr_broadaddr ifr_ifru.ifru_broadaddr /* broadcast
address */
#define ifr_flags ifr_ifru.ifru_flags[0] /* flags (low 16
bits) */
#define ifr_flagshigh ifr_ifru.ifru_flags[1] /* flags (high
16 bits) */
#define ifr_metric ifr_ifru.ifru_metric /* metric */
#define ifr_mtu ifr_ifru.ifru_mtu /* mtu */
#define ifr_phys ifr_ifru.ifru_phys /* physical wire

#define ifr_media ifr_ifru.ifru_media /* physical
media */
#define ifr_data ifr_ifru.ifru_data /* for use by
interface */
#define ifr_reqcap ifr_ifru.ifru_cap[0] /* requested
capabilities */
#define ifr_curcap ifr_ifru.ifru_cap[1] /* current
capabilities */
#define ifr_index ifr_ifru.ifru_index /* interface
index */
};

I'm guessing ifr_hwaddr the program is looking for is the
MAC address... I
took a look at the 'arp' command source code and I
think "ether_ntoa" will
give the address on FreeBSD. I notice the Linux man
pages don't have
ether_ntoa, so maybe this is the source of the problem.

See
http://www.freebsd.org/cgi/man.cgi?
query=ether_ntoa&apropos=0&sektion=0&manp
ath=FreeBSD+5.0-current&format=html

I'm not sure if this is helpful or not, like I said I'm just
guessing. I
haven't done any C programming since college. :-)
