Security :: /proc/net/packet Says My Server Is Acting As Network Sniffer - According To NSA Doc
Apr 25, 2011So, the NSA puts out some handy documentation on locking down a RHEL server (running centos 5.6 x64 myself) here, [url]. Under "Ensure System is Not Acting as a Network Sniffer" on page 63, it says that if any numbers below the first line in /proc/net/packet, that it is acting as a network sniffer.
I get the following output:
Code:
Unless I've been pwned, I don't know exactly what could be causing this. Besides samba, nmap (compiled from source, not from yum), screen, and rtorrent, there's nothing I've installed beyond the fresh install I did a few days ago. I was not running nmap when looking at /proc/net/packet.

Ubuntu :: License Key For Sniffer / Belarc?
Jul 19, 2011Got a laptop I'm working on, the motherboard is fried. So I am archiving the data from the hard drive using a USB to Sata adapter. Is there a program native to Linux that can locate software license keys on an external drive similar to how Belarc Advisor or License Crawler does from Windows? If not, I can slave the drive in a Windows machine, I just normally do data retrieval in linux so I can safely scan the data.

Red Hat / Fedora :: Determine Network Interface That Will Be Used To Send Packet For An IP?
Apr 9, 2010I'm writing to you because I encountered the following problem. My program displayes all network interfaces that are available in the system, but I would like to adda functionality in which a user can enter a destination address IP (ex. the IP address of the Google search engine) and will get information which network interface will be used to send it. As I know it is associated with reading information from routing table in the system. Maybe you know the API (functions/methods) which I could use to do it in RedHat ? I program in C/C++, but if you know how to do it in other programming languages (Java, Perl, Python) I will be grateful for any information.

View 2 Replies View RelatedGeneral :: Getting More Than One Udp Packet To Remote End Using Sendmsg
May 11, 2010I am trying to send data via UDP using sendmsg on the sending side, and recvfrom() on the receiving end.The setup for my data is to have an iovec that has a packet hdr, followed by an iovec that has a payload, then to have subsequent sets of these two types of iovecs. On the receive end, I have a while true loop that does a recvfrom() receiving a size of 1 hdr/payload combination.When I do send out a message that has a total of just 4 iovecs (hdr/payload/hdr/payload) and I use recvfrom on the remote end with a receive size of a hdr/payload set,only the first hdr/payload of the sendmsg is received.I was under the impression that using this while true loop would allow me to receive multiple sets of this hdr/payload combination that is sent out by sendmsg().

I know a few basic things but I feel like I am stuck with my problem.I want to send the Magic packet (wake on LAN) from my linux machine to another, but I am unsure how to approach this. I have google�ed my ass off but I am none the wiser. I found a few forums posts and programs that can do the trick and guides in how to use the programs but I have no idea how to install them.You have to know that my linux machine is a NAS server and has therefore only Konsole access (no GUI). As I said before I am pretty much a noob

View 1 Replies View RelatedFedora Networking :: Raw Packet Creation - Sending Specific DHCP Offer?
Jan 25, 2011I am trying to design an application which violates the DHCP. Specifically the difficulty in writing this application is physically sending the raw packet. I need some documentation on either a library that supports this or where to look for support for raw packet creation. I am not trying to create a raw datagram, that doesn't meet my needs because a raw datagram is still at layer 3 I need to craft a raw layer 2 PDU.
Specifically I want to
Send a very specific DHCPDISCOVER
Receive a DHCPOFFER
and pull apart the offer while never sending a DHCPREQUEST.
Specifically I am pulling apart various options that are sent in the DHCPOFFER. I have a raw DHCPDISCOVER already crafted and the formatted struct sockaddr_ll where I fault is I can't send the damn thing. Getting the file descriptor after calling socket is okay but what now? How would I write to that file descriptor and have it transmit?
Code:
int connfd;
struct sockaddr_ll bcast;
bcast.sll_family = PF_PACKET;
...
connfd = socket(PF_PACKET,SOCK_RAW,0);
