Technically, it will search the hosts.allow file first, then if no matches
are found there, it will check the hosts.deny file. So you could simply
put
ALL: LOCAL @local.domain
in the hosts.allow file -- or
ALL EXCEPT: .local.domain
in the hosts.deny file
hope this helps.

Subject: Dynamic NAT with a pool of IP address
Date: Thu, 18 Mar 1999 21:37:10 +0000
Hi,
I have installed several Linux machines acting as Internet Gateways
using IP Masquerading to hide a 192.168.x.x network behind a single
static IP address with great results so far, but I am now faced with a
problem that has me stuck, Linux-wise.
The site the latest gateway is intended for has IP address allocated
over the entire 192.x.x.x range, meaning I can't use Linux's
masquerading due to IP address conflicts with allocated IP addresses and
the site concerned is adamant that they will not renumber their machines
and routers. They currently use a IPX based web proxy and would like to
move entirely to IP.
What I intend to do is use NAT to change these address to addresses in
the 10.x.x.x range. However, since the allocated addresses are spread
throughout the 192.x.x.x range I believe that static 1->1 NAT mapping is
not possible due to the need to have several different 10.x subnets
available to handle addressing on both sides of the NAT. Thus, I wanted
to use dynamic NAT where the IP translations were picked from a 'pool'
of, say, 255 addresses. The 'clean' side of the NAT ( 10.x ) would then
contain a web proxy, acessed by those machines on the 'dirty' side of
the NAT, which would retrieve the web pages.
Having investigated this, it seems Cisco produce a router that would
handle NAT in the way I desire, and would enable my solution to work,
but ideally I'd like a Linux machine to carry out the NAT. The NAT
systems I've seen for Linux don't appear to handle this - are there any
that do ?
Basically :
192.x.x.x -> NAT with -> 10.0.0.x -> Web Proxy -> Internet
pool of
255 IP's
Also, is it possible to have the Web Proxy ( eg Squid ) on the same
machine as the one that is ( possibly ) performing the NAT ?
Any help would be appreciated.
Thanks,
Darren

Subject: Changing an Ethernet driver
I have an EtherExpress Pro\10+ loaded on my computer. It worked just fine
under 2.0.36, but it loaded the eepro driver. Now that I have upgraded to
2.2.3 it doesn't work but it is loading the eepro100 driver. I think this
my problem but I cannot find out either how to load the eepro back on
instead or what the parameter list is for the eepro100 to get it to work.
With the eepro I had to use these lines in my conf.modules file...
alias eth0 eepro
options eepro iox0x210 irq=11
When I enter these into the eepro100 it tell me io is an invalid parameter.
Can anyone help?
Thanks in advance,

Certainly does. Called IP Masquerading. Here's the HOWTo page on it.

I'm pulling my hair out trying to get my Linux system set up as a PPP
usable form Windows/NT. I get connected and the PPP connection is
apparently active but all I can do is simple PINGs to IP addresses.
(Can't even PING from Linux back to the NT).
Since my post of a couple days ago didn't yield an answer, how about
a simple example of working PPP Options, and startup command file
along with the configuration options used on the NT side.
It would also help to know the Linux kernel and PPPD version.
Thanks,
Dave Morris

Greetings
I am trying to resetup my Linux box for internet access. I rearanged
my hard drives so that now I have a removable "trayed" hard drives.
Now I am trying to get things setup again. It's been 2 years since I
have messed with my point to point protocol.
I "have" reread the PPP howto. but I seem to be missing something.
The system will dial, access, and log in. But I can't ping anything.
I type "ifconfig" and there will be NO ppp0 device.
Below is all that I have modified to get to where I am now to include
a portion of the /var/log/messages file. I have intentionally omitted
my user name and password.
What am I missing?
I am useing a USR 33.6 modem on a 233mhz Pentum

Subject: Routing question... (second try)
Date: 19 Mar 1999 00:40:11 GMT
Hi,
This is my second try at this question... My last post about a weekor so
ago didn't get me any answers... if this doesn't get me an answer,
I will go out and buy a bloody book on the topic I swear... ;-)
I am on a TCI cable network. At various times of the day, my connection is
so clogged as to make me wish for a good old 14.4 modem. Running traceroute from
inside and from various points outside the network has led to the discoveries that
a) the routing of traffic is ALWAYS asymmetric.. ie. outgoing packets are
ALWAYS using a different route than the incoming packets.
b) The first hop out of my cable modem IS definitely the bottleneck.
And incoming packets always have a much faster path in general than
outgoing packets.
So now my obvious thought is how do I make sure that the outgoing packets take
the same path the inocoming packets are taking. Basically I want to control the
first hop out of the cable modem. I am not clear on my routing/gateway concepts.
So could somebody tell me how to achieve this with a 2.0.37 kernel linux system.
( I am willing to upgrade/downgrade the kernel if needed). Reading the man pages for
route/ifconfig is only confusing me more. Is it under my control at all...???
Thanks
Chetan Ahuja

Well, chances are that any recent Fast Ethernet card you buy nowadays will

You actually got a connection with this interface....

That interface terminated and ppp1 is trying again.
>Mar 17 13:12:53 czech chat[1351]: Failed (NO CARRIER)
Modem is still tied up with ending ppp0???\
>Mar 17 13:13:10 czech ifup-ppp: pppd started for ppp1 on /dev/modem at
>Mar 17 13:13:32 czech pppd[1397]: Serial connection established.
Now ppp1 gets through
>Mar 17 13:13:33 czech pppd[1397]: Using interface ppp0
>Mar 17 13:13:33 czech pppd[1397]: Connect: ppp0 <--> /dev/modem
ppp0 causing problems? If it is then you may have problems at layer 2
(datalink layer) which is where frames are created and sent across the wire.
You seem to be getting frame related errors but I'm not sure what an fcs is.
This is just a guess. Check out why you have 2 interfaces going at once.
>Mar 17 13:13:36 czech kernel: ppp: frame with bad fcs, excess = 9088
>Mar 17 13:13:36 czech kernel: ppp: frame with bad fcs, excess = 47b2
Good Luck

I may have already posted this before, but I
never received an answer. How do you set
TCP/IP kernel parameters in Linux? Solaris
has the "ndd" command, and AIX has the
"no" command. Please help.

It looks like you'll want IP Masqurading. The resource page for it is
http://ipmasq.cjb.net/
There are true NAT packages for linux as well. I've never tried any of
them though. The IP Masq is built in to the kernel.

Subject: HELP squid and apache broken - no apparent reason
Date: Thu, 18 Mar 1999 22:18:31 -0600
I have had my RH 5.2 box set up for about a week now.
I have apache, caching name server, squid, diald configured and installed.
Everything worked fine for several days. To the best of my knowledge,
"nothing" has changed on the box. Haven't added any other software, etc.
Now, for no apparent reason, I cannot connect to the apache server from
another pc on my network. Connecting from the linux box to localhost,
servername, www.mydomain.org, all work fine, with no delays.
Connecting from my PC, however, simply dies. I have tried the linux server
name, the linux server address, etc. - nothing happens. The globe just
spins.
Connecting to squid will no longer dial out using diald. However, forcing
some other task on the linux box will dial out and connect (cron task,
getting my mail, etc.)
The name server appears to work fine. From my PC, I can ping the linux box
by name, name.localdomain.org, and any of the CNAMES I have configured in
the DNS server. No delays in response.
Any ideas what happened, and how to go about tracking down the problem? I'm
really frustrated. I've spent hours getting everything working just right,
it was working, and now it's just a pile of brown matter.
