I installed OpenWRT on a WRT54G-TM (linux 2.4). No problem so far!. I also installed tcpdump on the box.
I set the adapter in monitor mode.
Code:
wlc monitor 1
It created the prism0 interface. Tcpdumpíng is also possible using this interface.
Code:
root@cmWRT:/tmp# tcpdump -i prism0 -s 0
tcpdump: WARNING: prism0: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on prism0, link-type PRISM_HEADER (802.11 plus Prism header), capture size 65535 bytes
(data here)
Now, the small problem I got is that this won't sniff regular ARP, UDP or TCP packets. I sent udp packets over the air from a laptop and sniffed on both the wl0 and prism0 interface. Tcpdumping on wl0 showed the packets, but it didn't on prism0.
Is the problem related to the lack of a IPV4 address of the prism0 interface?
Hello
I googled for "tcpdump view HOST http headers" -- that fine
However can we do same for HTTPS like after the HTTPS gets decrypted by Apache ?
I think this is legitimate on the server where the site is hosted since at some point the Apache itself needs to get the HOST patrameter in... (1 Reply)
I've recently started learning to use TCPdump, and I find it pretty interesting. There's one thing I don't understand. When I tell it to capture packets on, say, the WiFi interface en1, it often captures packets sent or received by other hosts on the network. How can it do this? My... (3 Replies)

Hi ,
I have a typical situation. I have 4 files and with different headers (number of headers is varible ).
I need to make such a merged file which will have headers combined from all files (comman coluns should appear once only).
For example -
File 1
H1|H2|H3|H4
11|12|13|14
21|22|23|23... (1 Reply)

In one of the Unix Programming FAQ's they have the following headers in the program to catch SIGCHLD
#include <sys/types.h> /* include this before any other sys headers */
#include <sys/wait.h> /* header for waitpid() and various macros */
#include <signal.h> /* header for signal... (5 Replies)
