I have created a copy pypcap on github at this address:
https://github.com/hellais/pypcap.
I did some refactoring of the setup.py script and made sure that it will find
the libraries and headers on 64 and 32 bit ubuntu, fedora and OSX 10.7, 10.8.
I have not tested it with other distributions, but it should solve some of the
issues encountered by people in ticket:
http://code.google.com/p/pypcap/issues/detail?id=39,
http://code.google.com/p/pypcap/issues/detail?id=38,
http://code.google.com/p/pypcap/issues/detail?id=27,
http://code.google.com/p/pypcap/issues/detail?id=39.
Feedback and community involvement would be appreciated :)

What version of the product are you using? On what operating system?
Setup failed to build on our linux system from source, with a "can't find
pcap" error.
The following change to setup fixed the building problem:
for lib in (('pcap', 'libpcap.a'),
('pcap', 'libpcap.dylib'),
('pcap', 'libpcap.so'),
('wpcap', 'wpcap.lib')):

What steps will reproduce the problem?
1. Download the latest svn code. In setup.py replace:
'for sd in ('include/pcap', 'include', ''):'
with
'for sd in ('include', 'include/pcap', ''):'
so that it finds the right pcap.h in wpdpack
2. Follow the installation guide in Issue 28
3. mingw32-make gives an error ld.exe: cannot find -lwpcap
4. Move 'Packet.lib' and 'wpcap.lib' from wpdpack\Lib\x64 to wpdpack\Lib
5. Running mingw32-make again, gives the error 'undefined reference to
__imp_Py_InitModule4'
What is the expected output? What do you see instead?
Running 'make' and 'make install' should create a pcap.pyd file in the
Python26\Lib\site-packages directory, but I 'make' gives an error.
What version of the product are you using? On what operating system?
I am using the latest code from svn on Windows 7 64-bit
Please provide any additional information below.

Hi,
I am trying to do live capturing of packets but i am getting the error:
pc = pcap.pcap() # construct pcap object
File "pcap.pyx", line 189, in pcap.pcap.__init__ (pcap.c:1689)
OSError: no suitable device found
I think i have to set the network device
how can i do it???
Thanks,

this patch adds support for findalldevs() function.
tested on Linux, WindowsXP, MacOSX
There is one problem under windows.
there is no classic interefaces names under windows and this patch returns
what it gets from the OS (long names blabla). it's not a big deal but
lookupdev() returns ethX names. these ethX names are fake and don't know if
i should to do the same for findalldevs().

What steps will reproduce the problem?
1. Execute the following testcase while causing network traffic (for example
with "ping 8.8.8.8"):
#!/usr/bin/python2
# coding=utf-8
import pcap
capture = pcap.pcap('eth0', 1, True, 5000, True)
while True:
print(capture.next())
What is the expected output? What do you see instead?
capture.next() does only return every 5 seconds but with immediate = True it
should return every time network traffic is created. The same happens also if
capture.readpkts() is used instead but I'm not sure if this is maybe intended
there.
What version of the product are you using? On what operating system?
Operating system: Linux 3.16.3
pypcap: 1.1.2
Please provide any additional information below.
Trying to reproduce this with libpcap in C works as expected (to go sure that
for example the immediate mode is supported on the system).

When I captures packets in iteration mode (for ts, pkt in pc:) or through loop
I have long delays before recieving packets. This is particularly evident when
computer gets small amount of packets (if you set filter or network contains
small amount of computers).
I did some research. I think problem is related to timeout_ms (to_ms for
winpcap pcap_open_live). As far as I understand a value of 0 means no time out;
on at least some platforms, this means that you may wait until a sufficient
number of packets arrive before seeing any packets, so you should use a
non-zero timeout (http://www.tcpdump.org/pcap.htm). Winpcap documentation is
not very clear at this point.
I tried to delete lines
elif n == 0:
break
for loop and __next__ functions.
And all works fine.
I think this is the right approach - not break loop if timeout is reached.
Otherwise, you can get problems with timeout_ms values different from 0.
My OS - Windows 7. I uses lastes code from svn.

I've encountered a thread safety problem with pcap after importing the
pythoncom module in a separate thread. The code below exemplifies this
behavior. Here, the Debug Thread is locked in the pcap.pcap method, so you
never see the "PCap call successful" printout. On the other hand, if the
pythoncom module is imported in the Debug Thread (uncomment the import
statement at line 14 and comment out line 2), the code executes with no
problem. Anyone have any ideas?
Im currently running:
python 2.5.2
pcap-1.1.win32-py2.5
pywin32-210.win32-py2.5
WinPcap 4.0.2

What steps will reproduce the problem?
1. Set timeout_ms to less than 1 second
2. Run a capture on an interface with no traffic
3. Record the timings of the returned calls
This is pypcap 1.1 from svn (revision 102).
I traced the bug to the following line in pcap_ex.c:
#else
static u_char *__pkt;
static struct pcap_pkthdr __hdr;
struct timeval tv = { 1, 0 };
fd_set rfds;
int fd, n;
The timeval struct in the select call is set to 1 second timeout, regardless of
the timeout_ms value passed in. I attached a patch that changes the struct to:
struct timeval tv = { 0, 1000 };
i.e. a timeout of 1 ms. Sub ms timeout probably doesn't make sense anyway.
I think that's the right way to resolve that, unless I missed something.

What steps will reproduce the problem?
1. Use pypcap in a multi-threaded scenario, with each thread using a
separate pcap instance.
2. In each thread, read packets via pcap.next(), in parallel.
What is the expected output? What do you see instead?
Expected output is normal packet retrieval. Instead, one sees occasional
packet truncation (e.g., caplen 46, IP hlen indicating full 1500B). The
cause for this is the additional static pcap_pkthdr variable in pcap_ex_next
and the fact that the hdr variable in __next__ points to it, as races may
not reflect the right content at the time it is accessed.
I'm attaching a patch that fixes the problem for me. It removes the
static variable, thus restoring pcap's "caller owns value" semantics in
this particular case.
What version of the product are you using? On what operating system?
SVN trunk, Linux 2.6.

Maybe this is outside the scope of this project, but have you considered
providing a Python interface to pcap_sendpacket()? This would allow Python
apps running on Windows an easy way to send raw ethernet frames. Thanks.

I'm using pypcap 1.1 and made the changes from issues 14 and 22 so it would
build on a 64-bit setup.

Attachments:
pcap.pcap.__init__() has an undocumented parameter "timeout_ms=500" which
is passed to WinPcap. WinPcap's pcap_next_ex() function returns after this
time (in milliseconds) if no packets were received. The return code is 0 in
this case. But in our pcap.__next__() method, we do not deal with this
return code but just continue listening. This leads to problems, for
example with non-blocking I/O.
Example:
I want to stop receiving packets when a given timeout (e.g. an inter-packet
interval) has been reached. Moreover the user should be able to interrupt
at any time with Ctrl-C.
-- test.py --
import pcap, time
pc = pcap.pcap()
interval = 2
while True:
start = time.time()
print "Waiting for next packet..."
ts, pkt = pc.next()
end = time.time()
print "Packet received: %s (%s) %r " % (ts, end - start, pkt)
if end - start > interval:
print "Max inter-packet interval reached. Quitting."
break
--------------
Run test.py on an empty LAN. The program prints "Waiting for next
packet..." and blocks in pc.next() until a packet is received (which can be
long after the supposed interval has elapsed). Ctrl-C has no effect either
before the next packet is received.
And inserting pc.setnonblock(True) in order to switch to non-blocking I/O
mode doesn't change anything.
My config:
pypcap 1.1 on Windows XP SP2, WinPcap 4.0.1 (packet.dll 4.0.0.901), Python 2.5
Suggested patch: see attachment
The important part are the last two changes: If pcap_ex_next() hasn't
received any packets before the timeout (n==0) we just return None to the
caller (together with a timestamp). The rest is only for compatibility: If
a user explicitly specifies a timeout, he now must take into account that
.next() will return None if no packets were received. If he doesn't specify
a timeout, everything is like before and .next() will wait forever for new
packets.

Dirk

There is currently no support for saving a capture file with pypac. The
attached patch adds the support for the pcap_dump_open, pcap_dump_close, and
pcap_dump API functions internally, and exposes to python the setdumpfile(self,
filename) function to set up the packet dumper. Once enabled, any packet that
passes the filter will be logged to the dumpfile.
Not included is a way to selectively dump individual packets from python, as
that would require re-architecting things in such a way as to make pcap_pkthdrs
available to python to pass to pcap_dump(). Not impossible, but it would change
the semantics a bit.

I'm trying to write out some packets read from a .pcap file
into a new file.
It's not clear to me how to do this. The relevant part of the help text for
pcap.pcap I see is:
| name -- name of a network interface or dumpfile to open,
| or None to open the first available up interface
| snaplen -- maximum number of bytes to capture for each packet
| promisc -- boolean to specify promiscuous mode sniffing
| immediate -- disable buffering, if possible
| dumpfile -- name of a dumpfile to open, if necessary
| dumptype -- only open a dumpfile and specify its type
but unfortunately, it does not specify what value should be passed to the
dumptype argument.
I tried:
pcout = pcap.pcap(dumpfile="out.pcap")
and I got:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pcap.pyx", line 194, in pcap.pcap.__init__
OSError: no suitable device found
which looks to me like it's trying to open a network device for live capture.
I also tried:
pcout = pcap.pcap(dumpfile="out.pcap", dumptype="pcap")
which gives:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pcap.pyx", line 188, in pcap.pcap.__init__
OSError: Internal error pcap_open_dead.
Looking through
http://code.google.com/p/pypcap/source/browse/tags/PYPCAP_1_1/pcap.pyx I don't
see any occurrences of pcap_dump_open() so I'm wondering whether dumping of
packets to a file is actually implemented.

What steps will reproduce the problem?
1. prepare a capture packet,the pkt in file more than one.
2. p=pcap.pcap(file);pkts=readpkts();print(pkts)
3. you will find the each of pkts buffer ptr point to the same address
What is the expected output? What do you see instead?
expect all the pkts buffer is not the same.but got the result as this:
[(1276937965.531224, <read-only buffer ptr 0x00F7004A, size 81 at 0x00C94E20>),
