snort: error while loading shared libraries: libdnet.1:cannot open shared object file
 

i am using ubuntu 12.04. I've already installed snort and its supporting packets like barnyard etc. i got a trouble when i tried to test the snort with this command:

sudo /usr/local/snort/bin/snort -u snort -g snort -c /usr/local/snort/etc/snort.conf -i eth1

it said:

/usr/local/snort/bin/snort: error while loading shared libraries: libdnet.1: cannot open shared object file: No such file or directory

anyone can help me?

thanks before :)

Your other post was reported for being a duplicate and for re-opening/hijacking an old thread. The error very clearly tells you that you are missing the libdnet library. Did you try to look up how you would install this? Try "sudo apt-get install libdnet"?

And you don't say how you installed snort, since the instructions for the pre-built package on Ubuntu are different than for installing things via source.

I found that these must be installed in order: daq, libdnet, snort

I install libdnet from a src rpm -- I found that way to work best for me.

That is not really a good way to proceed. Unless you need some bleeding-edge feature, installing from package is a better way to go. Not only is it quicker, but FAR less likely to introduce instability in your system.
