Hi !
I understand there is no solution to sniffing
for local traffic on Solaris since the
kernel always used the loopback interface for
that.
I suggest to write a STREAMS module to sit on top
of the loopback driver.
Does anyone know if the loopback driver is a
STREAMS driver ? (Say, Solaris 8 a
Thanks for the answer!
There is nothing similar to ip_loopback_bypass
in Solaris.
When I run netstat -i, I do see packets that
are "passed through" the localhost interface.
Is there a real entity in the kernel which is the
loopback interface, may it be a driver (seems not to
be one), STREAMS mo
OK... Assuming I insist on enabling localhost
sniffing on Solaris to the benerfit of all:
How should I approach it?
How about pushing a STREAMS module on top of the TCP
driver? ( Is *that* a STREAMS driver nowdays?)

Does it handle lost segments well? I mean, when
you never get a segment, will NIDS understand that,
give up on the segment, and continue feeding the
user with the rest of the stream?
Similarly, does it track connections without

Hi,
I have pcap_dispatch sometimes returning value <0 and
pcap_geterr printing "Resource temporarily

The pcap handler is non blocking
(pcap_setnonblock was called with 1), the fd was
found with pcap_get_selectable_fd, it was select()ed
on and returned turned on. Yet pcap_dispatch

}
What I see is :

Is this because there are no packets to read?

Hi,
I am trying to run this small sample program on
Solaris 2.8, using pcap 0.8.3 on solaris 8. All I get
when I run this is:
pcap_dispatch: Resource temporarily unavailable
every select timeout. In a gdb session I see that the
fd I got from get_selectable_fd is set, so I call
pcap_dispatch. T
Hi,
The link to pcap-0.9.0-096.tar.gz in www.tcpdump.org

Also, this is a strip-down of something else that
select()s on more than one fd, so the select() is
kind of silly here...
I'll try to compile with the latest version.
Thanks again!

Your error was that you did not save the
return value from pcap_open_live. It's not
related to the ! operator. You can keep on
using ! if you want.
Change your original errornous

Just to same you some pain, here is another
error in your program: Look at your die()
function:
void die (_Bool onoff, char *text, ...) {
va_list(args);
va_start(args, text);
vfprintf(stderr, text, args);

Hi!
I'm having a weird problem on AIX 5.2. I have
a program that opens en0 and installs the
following filter :
((tcp[0:2] > 4 and tcp[0:2] < 50001) or
(tcp[2:2] > 4 and tcp[2:2] < 50001)) and (
net 0.0.0.0 mask 0.0.0.0 )
It runs well for a while. If I truss it I see a
lot of lines like
receives EINVAL from every read on
the bpf socket.
However, this does NOT happen if I use libpcap
0.8.1 . I suspect that something has changed
between 0.8.1 and the version that is now
in cvs.
This happens both on Uni-processor and SMP.
Thanks!

I'd prefer calling "pcap_open_live()" twice,
set the appropriate filters (which may be
different), call "get_selectable_fd()" on each
pcap_t, and then use select() to pick up packets
from any interface that may have some ready. That
way I don't have to deal with threads.

The buttom of the problem is this:
You excpect libpcap to call X::dumper in
the context of an instance of class X.
(The "real" first parameter of "X::dumper"
is a variable named "this" of the type "X*".)
But the libpcap API is not defining a

Hi,
I am running a local pcap application on a

host, capturing only packets going to and from a
specific interface. Sometimes I see several
packets coming in, in a row, and then several
packets going out, in a row, from that interface.
However, I know (from the content of the packets
