Compiling hping on CentOS

hping was recommend to me as a tool to stage a mock DOS test against one of our servers. I found that I did not have it installed on my CentOS 6 instance and could not find it with a yum search. I’m sure there is an rpm for it somewhere, but I figured it would be just as easy to compile it myself as to find the rpm. I was wrong. It probably was a _little_ harder to compile it, but I learned some things in doing so. So I’ll share my experience. It wasn’t too bad. I have nothing original to add here to what you find elsewhere, except that I didn’t find anywhere else with all these problems documented in one place. So I’ve produced this blog post as a convenient reference.

I’ve also faced this same situation on SLES – can’t find a package for hping anywhere – and found the same recipe below works to compile hping3.

The Details
I downloaded the source, hping3-20051105.tar.gz, from Try a ./configure and…

error can not find the byte order for this architecture, fix bytesex.h

After a few quick searches I began to wonder what the byte order is in the Amazon cloud. Inspired I wrote this C program to find out and remove all doubt:

/* returns true if system is big_endian. See - DrJ */
    printf("Hello World");
    int ans = am_big_endian();
    printf("am_big_endian value: %d",ans);
int am_big_endian()
     long one= 1;
     return !(*((char *)(&one)));

This program makes me realize a) how much I dislike C, and b) how I will never be a C expert no matter how much I dabble.

The program returns 0 so the Amazon cloud has little endian byte order as we could have guessed. All Intel i386 family chips are little endian it seems. Back to bytesex.h. I edited it so that it has:

/* # error can not find the byte order for this architecture, fix bytesex.h */

Now I can run make. Next error:

pcap.h No such file or directory.

I installed libpcap-devel with yum to provide that header file:

$ yum install libpcap-devel

Next error:

net/bpf.h no such file or directory

For this I did:

$ ln -s /usr/include/pcap-bpf.h /usr/include/net/bpf.h

Next error:

/usr/bin/ld: cannot find -ltcl

I decided that I wouldn’t need TCL anyways to run in simple command-line fashion, so I excised it:

./configure --no-tcl

Then, finally, it compiled OK with some warnings.

hping3 for Raspberry Pi
On the Raspberry Pi it was simple to install hping3:

$ sudo apt-get install hping3

That’s it!

Raspberry Pi’s are pretty slow to generate serious traffic, but if you have a bunch I suppose they could amount to something in total.

Now I’m ready to go to use hping3 for a SYN_FLOOD simulated attack or whatever else we want to test.
