Good morning, everyone...
I use IPCHAINS to filter packets coming from systems who are attempting
to spam a usenet news server running off my network. Here is a line from
my IPCHAINS used as an example:
ipchains -A input -j REJECT -p all -l -s 62.253.69.89
Now, let's say I want to block access for *everyone* in the 62.253
network, including this guy. I realize this is a harsh way to do things,
but running usenet news is a problem unto itself. ;-) You might be
surprised at the number of times blocking entire network blocks is
necessary the minute you turn on a news server.
So, wanting to block an entire network block of 62.253, which is
62.253.0.0-62.253.255.255 (if I am asking the question incorrectly,
please correct me) then I would do this:
ipchains -A input -j REJECT -p all -l -s 62.253.0.0/24
Is this not correct? What would work as I described, if this is the
improper notation?
I've learned a lot from reading this list, but this is one that always
has seemed to elude me. Thanking everyone in advance...
Dave
