O great devs that know grep I have a log that I took from a local company's router that got DOSsed yesterday (they sell very nice sandwiches) and I wanted to know how I can take only the IP's from the log so that I can take action against the users (contacting the abuse if the ISP)

    Try this:

    cat "path/to/logfile" | grep -e "[0-9]\{0,3\}\\.[0-9]\{0,3\}\\.[0-9]\{0,3\}\\.[0-9]\{0,3\}" -o

    @inpothet The command I posted seems to work and grabs all ip addresses. However, I don't know if that is exactly waht you're looking for

    Don't even try. The machines will be hacked ones. The only one you will find are users who do to know about their computer's shady second life

    @Kimmax only thing I wanted to do is to contact the ISP as I got notice that this was happening Al over the Netherlands yesterday and people are speculating it was the Turks due to the bad situation between our countries
