I've googled around for a while trying to find a good libnet tutorial but most of them appear to be out of date or lacking on good code examples. What do you recommend for learning libnet? I'm also having problems compiling programs using the libnet headers; what's the flag(s) needed for this? ...
I have recently started playing around with libnet and using it to generate IPV6 packets. I am very new at programming, however, I am quite happy with the library. I have one problem with it though. It seems that libnet currently does not have the ability to properly calculate checksums on IPV6 packets. Being so new to programming,...
I'm building an FTP client using Net::FTP. The documentation states that the new constructor has a Host option which can be a reference to an array with hosts to try in turn. I don't seem to be able to get this to work. I'm using ActivePerl under Windows XP. Here's my code: @try_these = ("turing.unh.edu", "euler.unh.edu"); $ftp = Net::F...
I'm using pylibnet to construct and send UDP packets. The UDP packets I construct in this way all seem to have invalid checksums. Example: # python Python 2.4.3 (#1, Sep 3 2009, 15:37:12) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> >>> import libnet >>>...
Could someone provide some links to additional documentation or tutorials for the CPAN module Net::Libnet? ...
Hello. Writing a program on C, using libnet and libpcap to impersonate an RSH client and inject my own command on the server machine, running RSHD. As I understood, the command should be in the 'payload' of the ACK packet, but in the format, that RSHD will pass it to the shell. How should I assemble the packet to achieve this? ...
I just took a glance at the introduction of libnet, seems it mentioned support for udp,*ip*,but not tcp? Does it support tcp at all? ...
I am building a NAT program,I change each packet that comes from our internal subnet, change it's source IP address by libnet functions.( catch the packet with libpcap, put it sniff structures and build the new packet with libnet) I am trying to build an http packet. When I look on wireshark, I see that the new packet that I have built...
Hi, I need to look up MAC address in the local network and I'm using Linux. What I do is send a ARP request with libnet, but after I send 3 requests, the cache still won't update. I use wireshark to catch the packets. From wireshark, I did get 3 ARP replays, after each of my ARP request. Does anyone know how come the ARP cache won't ...
I want to capture ip packages on one server, and then forward the packages to another server by libnet, who has some examples ? thanks in advance. ...
when i install libnet by sudo apt-get install libnet1, the program can not find libnet.h and I also can not find it at /usr/local/include or /usr/include. so i download the libnet and make it, but I get the errors make -C lib/ lib make[1]: Entering director `/home/liuqiang/workspace/libnet/lib' gcc -O2 -Wall -Werror -Wno-unused -Wstrict...
I write a demo with libnet, but get an error when call the function: libnet_error(LIBNET_ERR_FATAL, "libnet_open_link_interface: %s\n", errbuf); The error is "error: ‘LIBNET_ERR_FATAL’ undeclared (first use in this function)". my gcc command is: "gcc demo.c libnet-config --defines --cflags --libs", and run on ubuntu. I want to know ...
I hava captured some packages by libpcap and built ip header. The package is a const u_char type and named payload, so how to pass the payload to libnet , then I can forward the payload to another ip ? which libnet api can work for this ? ...
I notice that many demos with libnet, they build many headers(ip icmp arp ……) for payload(the data need to be send). I guess the link layer header must be built, because the libnet works in link layer, i am not sure it is right. Now I want to forward some ip packets, can I just only build the ip header? ...
