hello out there,
I am setting up a firewall with ipchains.
question: is there an example of a *secure* configuration for a small sized
company with www, dns, mail, news, ping, traceroute ?
thank you all
I think you'll find what you want at my web site. There is a tutorial at
<http://rlz.ne.mediaone.net/linux>. There is a free version of my firewall
design program at <http://rlz.ne.mediaone.net/linux/firewall>. The program is
intended for home users, but you've described your needs as being simple
enough that this program should do more than you need.
As for *secure*, that's in the eye of the beholder. A firewall is a
lower-level security measure, but it is not the end all and be all. You will
still have to pay attention to what daemons you are running, tcp_wrappering,
and general system security. I think the paper will give you a good start.
I haven't publicized my site on usenet in general because it is being served
off of a home computer over a cable modem. There are bandwidth limitations...
;-) And, my ISP's Linux customer base in this area keeps me supplied with
more questions than I can possibly answer.
Where can I get other filters besides postscript??? I'm trying
to print from a laserjet printer but the only filter I've got
has been for postscript files. I only have an hpleaserjet without
the postscript module.
