UPDATE: 5.9.1 seems to work without the need to manually compile libssh. Simply replace the libssh part below with
sudo apt-get install libssh-dev
Also, grab 5.9.1 using
wget -c http://freeworld.thc.org/releases/hydra-5.9.1-src.tar.gz
Wikipedia describes THC-Hydra as “… software … that uses a dictionary attack to test for weak or simple passwords on one or many remote hosts running a variety of different services.” Its useful for doing quick tests against your servers to make sure that your users are not using simple passwords. In pen tester speak, this is called a brute-force attack.
Here are the steps needed for installing it on the 32-bit version of Ubuntu 10.10 (Maverick Meerkat).
Make sure you have all the necessary development tools (i.e. libraries, compilers, headers) and the source files for GTK:
sudo apt-get install build-essential linux-headers-$(uname -r) libgtk2.0-dev libssl-dev cmake
Before we compile Hydra, we need to install libssh. For some odd reason, hydra does not like the libssh-dev package that comes with Ubuntu.
wget -c http://www.libssh.org/files/0.4/libssh-0.4.6.tar.gz tar -xvzf libssh-0.4.6.tar.gz cd libssh-0.4.6 mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug .. make sudo make install cd ../..
Download and extract the THC-Hydra tarball
wget -c http://edwincastillo.com/wp-content/uploads/2010/12/hydra-5.9-src.tar.gz tar -xvzf hydra-5.9-src.tar.gz cd hydra-5.9-src
Now you are ready to compile:
./configure make sudo make install
You are now ready to use Hydra. Type ./hydra -h to get syntax help. The GUI version can be started by running xhydra.
If you have a GMail account with IMAP enabled, you can use the following example to test hydra:
hydra -S -l email@gmail.com -p your_password -V imap.gmail.com imap
I believe that I am only at a beginning, only knocking at a door, and I believe that the best is yet to come. –Pat Buckley

Thanks! Just what I needed! Great job.
Well , In the first step the url is wrong it should be
http://www.libssh.org/files/0.4/libssh-0.4.6.tar.gz
Thanks for the correction. I have made the change.
thanks a lot for the help! this worked perfectly
Hey I m getting some errors on the first step plz help , thought it was my computer problem but on my friends laptop also this occurred
After I type
“sudo apt-get install build-essential linux-headers-$(uname -r) libgtk2.0-dev libssl-dev cmake”
I get the error
”

Help….
Hi Vailhav,
Are you using Natty instead of 10.10 (Maverick Meerkat)? The reason I ask is because there seems to be a bug in Natty. Let me know.
Also try Synaptic’s feature to fix broken packages

Hi I have followed the instructions and am still receiving the same error when running the make command.
I have installed the libssh as the guide suggests above.
The out put of the make command is below:

Hi I wanted to add a update. I have re followed the steps above and am still getting the same error.
I dono if it makes a difference but I am running Kubuntu 64Bit.
Please help me get this working.
Thanks,
Dave
Hi Dave,
I downloaded Kubuntu 10.10 64-bit, installed it in VMWare, ran all updates and than followed the instructions above. I did not get any errors. The error shows that there is a syntax error in hydra-ssh2.c. Could it be that the file you downloaded is corrupt? Try downloading the files again from here: http://freeworld.thc.org/releases/hydra-5.9-src.tar.gz
Dave i am getting the exact same error messages. Configure goes well and when i type make i get the same stuff. I have tried hydra-5.4 and hydra5.9 with the same results.
I am on Maverick 32 bit, fresh install with all updates. After my botched 5.4 install i cleared everything out and started fresh on this page following every step.

I believe your libssh is not well setup, that’s maybe why you got all these errors
After I ./configure it lists several items not found. I’ve install all but SAP/R3. Are these important?

When I use the GUI, on start it says:
Error: Compiled without LIBAFP support, module not available!
Where can I find LIBAFP?
You only need support for what you will use. In my case all I want is SSL support so I install libssh. AFP is for Apple Filing Protocol Support. The main page for the open source version is http://sites.google.com/site/alexthepuffin/home. I found a deb package of the tested version (0.81) here:http://sourceforge.net/projects/afpfs-ng/files/afpfs-ng/0.8.1/. I haven’t tried it but this should work:
sudo dpkg -i afpfs-ng_0.8.1-1_i386.debThanks for the tutorial, it’s very nicely done. It almost worked for me.
Any advice on this error during the make?
hydra-mysql.o: In function `start_mysql’:

make: *** [hydra] Error 1
It’s something with the mysql bit. But I don’t know what to do about it.
Nevermind. I was trying to compile hydra 5.9.1 but I downloaded 5.9 like in your tutorial and it worked fine.
Ubuntu maveric, followed instructions from the post, but I get this error after typing “make”:
hydra-5.9-src$ make

Try this:

Hey that solved my problem thanks, I’ve been struggling with the compilation process for a few minuted but that cleared everything up!
Great! It works! I’m using Ubuntu 10.10 x64

when i past this link to my terminal getting error message “Connecting to http://www.libssh.org|91.121.49.183|:80… failed: No route to host” anyone got an idea?
Thank u so much man, it was brilliant!
i got it to work in 11.04 the way you have it thanks man
Very nice tutorial, everything worked perfectly.
Thank you very much!!
thanks
Notes for Hydra module dependencies for Ubuntu 10.x:
====================================================
Here are the additional modules you’ll need to build Hydra with support for these:
===================================================================
MySQL:
——
apt-get install libmysqlclient-dev
===================================================================
idn:
—-
apt-get install libidn11-dev
===================================================================
pcre:
—–
apt-get install libpcre3-dev
===================================================================
postgres:
———
apt-get install postgresql-client libpq-dev
===================================================================
svn:
—-
apt-get install libsvn-dev
===================================================================
ncp:
—-
apt-get install libncp libncp-dev
===================================================================
firebird:
———
apt-get install libfbclient2 firebird2.0-dev
===================================================================
afp:
—-
apt-get install libfuse-dev libgcrypt11 libgcrypt11-dev libgmp3-dev libgmp3c2 libreadline-dev libgmp3c2 libgmpxx4ldbl automake
Download the appropriate afpfs-ng package from Sourceforge. If running 64-bit Linux, you’ll need to grab the source tarball and compile rather than using the .deb Here is the one I got: afpfs-ng-0.8.1.tar.bz2. If compiling from source, one twist after you do the ./configure, make, make install is that the make install does not copy the C header files (like afp.h) to /usr/include/afpfs-ng/, so I had to manually do a mkdir /usr/include/afpfs-ng and then cp /include/*.h files from the afpfs-ng build directory manaully to /usr/include/afpfs-ng. When you’re done, afp.h and about 8 other header files should be in /user/include/afpfs-ng. Otherwise if you don’t do this, when you do the ./configure for hydra, it will say it’s can’t find the AFP dependencies.
Also add /usr/local/lib to /etc/ld.so.conf and do another ldconfig. That’s where libafpclient.so was installed by the make install, at least on my system.
===================================================================
oracle:
——-
download the following three Oracle Instant Client rpm’s from Oracle ( http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html ) – you’ll need to register for an OTN online account (free).
oracle-instantclient11.2-basic-*.rpm
oracle-instantclient11.2-devel-*.rpm
oracle-instantclient11.2-sqlplus-*.rpm
Then you need to convert RPM to DEB format, so do this apt-get:
apt-get install alien libaio1
Then run alien to convert and install:
alien -i oracle-instantclient11.2-basic-*.rpm
alien -i oracle-instantclient11.2-devel-*.rpm
alien -i oracle-instantclient11.2-sqlplus-*.rpm
Add the following to /etc/ld.so.conf (that’s where it put my libs for version 11.2 – substitute your version there)
/usr/lib/oracle/11.2/client64/lib
Then do an: ldconfig
Then when running ./configure for hydra, use the –with-oracle and –with-oracle-lib switches. Here is the one I used.
./configure –with-oracle=/usr/include/oracle/11.2/client64 –with-oracle-lib=/usr/lib/oracle/11.2/client64/lib
Then one final twist before you do the make – you have to edit the Makefile and manaully add the Oracle include dir to the XIPATHS var. Here is mine where I had to manually add to the end:
XIPATHS= -I/usr/include/subversion-1 -I/usr/include/apr-1.0 -I/usr/include/subversion-1 -I/usr/include/mysql -I/usr/include/afpfs-ng -I/usr/include/oracle/11.2/client64
(Remember to substitute your include path if different.)
SAP/R3

Only one I didn’t do. I’ll leave that one for someone else to document…
