Can't install Firewalk - libnet problem

[Petester]

Hi guys,

I'm trying to install Firewalk 0.99 but when I use the configure command I get back errors about libnet installed. I'm pretty sure it is installed tho by default.

root@bt4:~/Firewalk-0.99.1# ./configure
loading cache ./config.cache

checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking build system type... i686-pc-linux-gnu
checking for gcc... gcc
checking whether the C compiler (gcc -O3 -funroll-loops -fomit-frame-pointer -pipe ) works... yes
checking whether the C compiler (gcc -O3 -funroll-loops -fomit-frame-pointer -pipe ) is a cross-compiler... no

checking for a BSD compatible install... /usr/bin/install -c
checking for libnet_build_ip in -lnet... no
configure: error: No libnet? No firewalk.

As far as trying to install libnet, thats another headache too:

root@bt4:~/libnet# cp makfiles/linux.mak port.mak
root@bt4:~/libnet# make
make -C lib/ lib

Any advice anyone please?

Hi Pentester,

Am facing the exact same problem installing firewalk that
you've mentioned. However, I was able to install libnet without
any probs. Try downloading and installing libnet 1.1.2.1.

But even after installing libnet I got the same exact error
message again while trying to install firewalk.

Please help us guys

EHLO,

Perhaps you've already tried this otherwise it's worth a try.

Do like this:

1. Visit this mirror site: packetfactory[dot]openwall[dot]net/projects/firewalk/index.html
2. Download "latest version" 5.0

3. Download libnet 1.1.x from provided link in mirror site.

4. ./configure && make && make install for the just downloaded libnet

5. Do ./configure in the above downloaded 5.0-version. Do you still have the same problem? Otherwise continue with editing the firewalk.c at line 191 and add "break" after the default switch-case.

6. After editing the source code you're now able to compile it. Do "make" and continue with "make install" and after that target the specified router/fw
