This is why I broke down and signed up with TZO. The price is not to bad I
think $50 a year + internic fees and I have my own domain name running off
of my DSL account.

Basic setup looks OK; I think your patterns aren't matching.
Are you sure the To: lines don't just have your own name
when procmail sees it? Try filtering on ^Sender or something
else.

Reject triggers an ICMP message to the sender of the offending packet,
saying "destination unreachable". Deny suppresses that, silently
dumping the packet. Often, deny is preferred, because it gives the
potential attacker no information, it's as if the destination host
didn't exist at all.

Ok I have just recently found Linux (Redhat 5.2) and love it. I have
been tinkering with computers since TS1000's where all the rage. And
linux does some much stuff that I'm unsure of how to ...
Here's what I have a PII 333 with 6.4G, 64Mram Ne2000 compatible card
and external 56K modem running linux only, I blew windows 98 away the
last time it crashed and gave all the hard drive space to linux and I
have a 386DX33 with 540M, 8M ram Ne2000 compatible card . And a 5 port
hub.
What I mostly do is surf the net with the PII running redhat and I am
learning C++ programming and my kids play games and occasionally do
homework on the 386 running WFWG 3.1 (Yes I know that this box could run
linux but the video dosen't run X very well (crashes alot probably due
to a crude vga video card). Both are connected to there own printers.
OK I'll get to the point I would like to give the kids net access
through my box. And while both boxes have net cards they are not being
used at this time just because there isn't any need to share
printers or files. Can I do this and if so point me in the right
direction. One more thing is that I have promised my kids another
computer in the near future so they can quit fighting over the one 386.

Subject: LAN network and Cable modem
Date: Sun, 14 Feb 1999 18:25:04 -0500
I am new to linux and have been working for days to set up a network
with a linux box connected to the internet. I hoped to have the linux
box distribute internet access to all of the computers on my LAN using
IPMasq. or something similar. The problem is my cable modem and
LAN both use ethernet cards and when I have the card connecting the box
to the LAN, DHCP fails at bootup for my cable modem. Does anyone know
why this would be happening, or if it might be happening because my two
ethernet cards are from the same manufactuer.

Yes, linux can forward packets based on port number. Take a look at
ipautofw and ipportfw. These are standard packages for Debian and should
be standard with RH as well (I'm assuming you are using RH).
Hope this helps,

I have the Netgear 10/100 FA310TX network card and it works flawlessly!
(at 10 Mbps at least, haven't had a chance to try it at 100). It uses
the Tulip drivers which can be compiled into the kernel or loaded as a

Had a very similar peroblem myself where the 3c905(B, in my case) would hang in
Linux after a few days use or heavy network traffic - especially over-the-wire
backups. This despite using latest driver module (RH 5.1 2.0.34). Even with
debugging on all I got was complaints that the were giant-sized packets. It
seems to me like memory leakage of some sort, or garbage collection. I finally
gave up and swapped it with a 3c515 from my wife's win98 box. Both are now
working faultlessly at 100mbs through a Netgear 8 port 100mbs hub (no option
for 10mbs).
I kept reading some mention of patches for the vortex driver but was not able
to find them. I hope you have more luck.

Subject: DNS Questions?
Date: Sun, 14 Feb 1999 22:10:35 GMT
Luca,
I succesfully configured the DNS caching server and the linux.bogus as
described in the DNS-HOWTO. I am excited about accomplishing this
task, yet I have a couple unanswered questions.
My dsl connection gives me a static ip, but the ISP has a name
resolved to it. You can see (below) that if I do a reverse dns lookup
on it, it will return the pacbell name. I am planning to run a primary
DNS on my machine and reconfigure brie.com to point to it. The dns on
my machine will "resolve" www, ftp and so forth. When someone does a
reverse dns lookup on 207.212.133.10 will they get
adsl-207-212-133-10.dsl.pacbell.net or brie.com or both? Will this
create problems?
$ nslookup
> 207.212.133.10
Server: localhost
Address: 127.0.0.1
Name: adsl-207-212-133-10.dsl.pacbell.net
Address: 207.212.133.10
When both are aliases to the same ip will it give
$ nslookup
> 207.212.133.10
Server: localhost
Address: 127.0.0.1
Name: brie.com
Name: adsl-207-212-133-10.dsl.pacbell.net
Address: 207.212.133.10
Second question. I noticed in the DNS HOWTO in the zone file for linux
bogus (Section 4.2) that a secondary mail exchanger had been
established (quoted below). How does this work? Does this mean that
that mail exchanger mail.friend.bogus is configured to hold email when
the machine mail.linux.bogus is down? What if I have only one mail
exchange and my machine is down? Will that mail bounce?

right, so why not have a significant-sized buffer? cdrecord does,
and lets you set it to pretty much whatever you want.

Note that one of the limitations often cited of CERT is that it is _not_
a full disclosure service. CERT issues advisories, but does not always
provide all information required to assess, recover from, or prevent a
given exploit.
You might want to check also with BUGTRAQ and the newly announced HERT
(Hackers Emergency Response Team), both of which specifically address
the full disclosure issue.
