1. The problem statement, all variables and given/known data:
My system is Redhat 5.6. I want to install snort in my system which requires following dependencies.
1. Libpcap 1.0.0
2. Libdnet 1.12
3. daq 2.0.4
And then finally we can install the snort.
The problem is that when I install libpcap 1.0.0, it gets installed properly but after that when I install daq , it says that libpcap 1.0.0 not found or missing.
I checked rpm -qa | grep libpcap , it gives me that
libpcap-devel-0.9.4-15.el5
libpcap-0.9.4-15.el5
are installed.
I dont know why I am unable to upgrade it to 1.0.0.
And if you have any other idea so that I can install snort on my rhel 5.6.
Please help me.

Which command did you run exactly

Hi, This error was while installing DAQ...
I just run ./configure in the DAQ directory.

Building and installing libpcap by hand does not inform your package manager of it. (Installing it by hand also probably installed it into nonstandard locations which your package manager, or ./configure, would not search for libraries inside). You should undo all the changes you made and install an appropriate RPM for your system instead.

Otherwise, you will be forced to build everything by hand, and keep doing so, when you need upgrades for those packages and anything depending on them.

Thanks a lot. Let me try this.

Hi I think I have configure the snort properly. Now the problem is when I log on with root everything works fine, but if I log on with other user account , it gives the following error.
ERROR: Can't start DAQ (-1) - socket: Operation not permitted!
Fatal Error, Quitting..
I am not getting how to resolve this.
I have created one group called 'snort' and added the user to that group.
Please guide me.

It inevitably requires administrator access to snoop on your system in that way. You could use sudo instead of logging into a different account.
