Does anybody know if a Check Point's VPN-1 firewall on one side of a WAN can
talk to a Linux IPsec PC on the other side? Using SWAN or Pluto?
Did anybody ever try or has a running setup for this?
Any hints / suggestions will be appreciated.
Thanks,
Bill.

Hello:
I have set up a network with a mac (0s8.51) and a linux machine running
RH5.2 and netatalk. I can mount volumes on the linux side just fine,so
it appears that I have set up the system right, but when I try to ping
the IP of the linux box, it doestnt work.
I originally configured the network using ethertalk, then switched over
to a hardware ethertalk/localtalk bridge. I can still mount linux
volumes on the Mac via localtalk, but pinging doesnt work. It works
when I used ethertalk straight out of the mac though.
Can anyone shed some light on why using localtalk doesnt allow pinging?

wrong, they are both the same thing, just the name is different. besides
what good would NAT be if you still had to have a gazillion valid external
addresses. NAT is what the non unix community call it. Masq is what the
Unix community call it. That's the only difference!

Hi,
I'm reading the ipchains howto right now and am trying to design a
configuration for our linux redhat servers to use as gateways to the net on
a LAN. Basically I have a subnet of live ip addresses to give workstations
that I want to be able to get back to from anywhere on the net, and I also
have the rest of the workstations on the 192.168's. Can someone tell me what
the configuration would be to to allow everyone to get out(both sets of
ip's). Also allow for masquerading. Would it be something like this:
ipchains -A -m forward -s 192.168.1.0/24 -d 0.0.0.0/0
ipchains -A -m forward -s x.x.x.x/x -d 0.0.0.0/0 -b
Is this right? Do I need anything else? Thanks in advance!

Subject: Re: Problems moving from diald to cable
Date: Tue, 23 Mar 1999 18:55:12 GMT
Replying to my own post, because the solution may help somebody else down the
track.
It turns out that there was nothing wrong with my linux setup. The problem
was with the cable modem and/or Road Runner service. I initially setup and
tested the cable modem connection using a different machine running Wintendo,
and it appears that road Runner had somehow linked the NIC ID of that machine
with the ID of the cable modem, and while it would allow another NIC to get a
DHCP connection, it would simply not pass anything outside of its own subnet
after that!
When I reconnected the original machine again, it all worked beautifully from
Windoze, OS/2 or Linux.
So the solution appears to be simply to reset the cable modem when switching
from one machine to another. Now that I have done so, my gateway box is
working beautifully, but the original box won't work unless I reset the
modem. Not that I need it to anymore - the linux box will remain connected
from now on.
Cheers,
Jon.

Well it's definitely intentional

if(ifr.ifr_addr.sa_family==AF_UNSPEC)
{
memcpy(ifr.ifr_hwaddr.sa_data,dev->dev_addr,

(*(struct sockaddr_in *)
&ifr.ifr_addr).sin_family = dev->family;
(*(struct sockaddr_in *)
&ifr.ifr_addr).sin_port = 0;
}
goto rarok;
But, no, it is not right and it's fixed in 2.2.2

Subject: 2.2.3 PCMCIA Ethernet DHCP Woes
Date: Tue, 23 Mar 1999 19:04:36 GMT
I've installed a 2.2.3 kernel on my Red Hat 5.2 laptop (ThinkPad 765D).
I downloaded all the necessary RPM updates, and the kernel appears to be
working. I also got and compiled the PCMCIA 3.0.9 package, and that seems
to be working well in addition. I'm trying to simultaneously configure 2
ethernet cards so I can use this as an "internet proxy" with IP
Masquerading.
However, it seems that DHCP paralyzes the card manager. If my eth0
device is set to use DHCP in the /etc/pcmcia/network.opts script, then
everything looks OK at boot. However, it never creates eth1. /var/run/stab
claims that the second PCMCIA slot is empty, even though cardctl reports
(some) information for the card there. But all networking via eth0 works
correctly.
Here's the weirder part: when I shutdown or halt, I get a message with a
DHCP address for eth0, followed by cardmgr initializing eth1 and a DHCP
address for eth1. What the heck? It's like cardmgr got suspended until
shutdown?!?
If instead I manually assign networking configuration info, everything
works fine. However, I cannot do that "for real" since the internet
connection doesn't (necessarily)use a static IP address. One of the Red Hat
updates for a 2.2 kernel was a new DHCP RPM, so I wonder there's a problem
with that, or whether I'm just missing some key configuration steps. Any
help would be appreciated.
Thanks,
Aaron

When you have done it, you can provide us with the HowTo. I have
heard people talk about this, but I have never seen it done.
You need to get you two machines to agree on each others IP numbers.
Do services such as telnet, ftp and HTTP work?
You need to be sure that the smbd and nmbd ports are accessible
over the PPP link.
Once you have got started, you can follow the procedures in

You either use Microsoft's telnet server (from one of their Resource Kits, IIRC),
or buy a telnet server. We have used the Ataman telnet server successfully.
I've been told that the Microsoft telnet server has large stability problems, but
I cannot speak for or against it myself.

Perhaps a little pragmatism is called for.

I totoally agree with Carlson in theory. But if you want to do it
anyhow:
ftp://ftp.wcl.bham.ac.uk/pub/bam/patches/pppd-2.3.5-get-ms-dns.diff
This adds a new PPP option "ms-get-dns" defined thus:
+Implement the client side of RFC1877. If pppd is acting as a client
+to a server that implements RFC1877 such as one intended to be used
+with Microsoft Windows clients, this option allows pppd to obtain one
+or two DNS (Domain Name Server) addresses from the server. It does
+not do anything with these addresses except put them in the
+environment that is passed to scripts. The /etc/ppp/ip-up script
+should use this information to perform whatever adjustment is
+necessary. Note: RFC1877 is a horrible protocol layering violation,
+the correct approach would be to use DHCP after the IPCP phase.
The purists who maintain pppd not only refuse to incorporate this
patch into pppd but clearly regard the suggestion a so far beneath
contempt that they refuse to even respond to my e-mails.
Personally I'd rather IPCP could operate without even IP address
discovery. That way ip-up would get called with remote/local IP
addresses 0.0.0.0 and could use a varient DHCP client to do the job
properly.

4th time today. So far that is. I've hardly started browsing.
Must be getting close to a record even for this question.
Anyone know the stats on this?
What is the largest number of times the "broken reverse DNS" question
has appeared in a 24-hour period? (I don't recall seeing more than 4).
What is the longest period between instances of this question in the
last few years? (I'd guess not more than 5 days).
Just when did it start appearing frequently? (I'd say 1996)
Is this really the current number one FAQ[1] in this newsgroup?
(Almost certainly. It's hard to judge because only other contender
that I can think of is the question to which the answer is "you need
to be using IP masquerading". The problem is it kinda difficult to
come up with a simple search criterion that'll find the masquerading
question).
Is this really the number on all time FAQ in this newsgroup?
(Probably).
Is this even the number on all time FAQ in the whole comp.os.linux.*
hierachy? (Possibly not, "how do I remove LILO" had a couple of
year's head start).
> Any ideas?
Yeah, read the newsgroups you are about to post to.
If you don't then you run a very high risk making a yourself look
foolish[2] by asking the _most_ frequently asked question in the
group.
[1] FAQ in the literal sense of being frequently asked.
[2] "foolish" is a very gentle term. Over the years I've been
criticised for some of the names I've called people who have asked
this question so now I'm sticking to very mild rebukes.

The "tulip" driver works for this card, though in some situations you may need
to get the newest version of it (v0.90 or so; RedHat 5.2 ships with v0.89 or
somesuch) from:
http://cesdis.gsfc.nasa.gov/linux/drivers/tulip.html
The compilation instructions are a little out of date (w.r.t. RedHat 5.2),
but it's pretty easy to install nonetheless. Basically, just cc it and
copy it into the net drivers directory! (Read the instructions in the source
code first.)
It's not obvious, but this SOHOware card uses a Macronix (MXIC) chipset which
is compatible with the DEC tulip chipset. You'd have to (physically) look at
the card pretty closely to figure out that Macronix is the manufacturer. The
device list from the MS Windows control panel will identify the card and
chipset for you (assuming you got it working under Windows -- see, Windows
isn't totally useless ;-))
But even armed with this knowledge, it's not always obvious which driver
goes with which chipset. I figured it out by trying a few until I found one
that worked!
A better method (and the one you've chosen :-) is to ask someone if they
know the answer. An even better method would be to use www.dejanews.com.
I wish I had done that to begin with; it would have saved me a lot of
grief!
Good luck!

Subject: IP Alias, IPFWADM and IPPORTFW Help Needed!!
Date: Tue, 23 Mar 1999 15:29:07 -0500
Trying to set up a firewall with several IP Aliased addresses. Addresses
are as follows:
eth0 IP address a.b.c.20 for ethernet card connected to Internet. Used
as masq'ed interface to internet
eth0:0 IP address a.b.c.21 to be used to redirect to internal web server
192.168.1.x
eth0:1 IP address a.b.c.22 to be used to redirect to internal mail server
192.168.1.y
eth0:2 IP address a.b.c.23 to be used to redirect to internal mail server
192.168.2.z
I've been able to set up the rules for the eth0 interface and firewall. I'm
running into trouble getting the aliased interfaces to forward packets to
the respective internal IP addresses. I've tried IPPORTFW, but I'm still
running into trouble. Can someone help me out???
Thanks,
Ken McCord

Subject: Linux as a firewall!!

I've got a couple of questions, I hope someone has the answers, or ideas at
least :-).
I've got DSL installation in about a month. I want to have my 4
workstations, behind a firewall, and still have a DMZ (Demilitarized zone).
I know I can setup the Linux box as a multihomed system with 2 network
adapters, but can I put in 3? 1 for access to the Intranet, one for the
DMZ, and one for DSL? Here's a simple layout of what I'm trying to
accomplish...
[Internet (DSL)]
|
|
[Firewall (Linux)] ---- [DMZ]
|
|
[Intranet]
Make any sense? I know all about ipfwadm, so I'm really just curious as to
how to implement the network. Without the DMZ, I can clearly see how a
multihomed system with 2 network adapters would work, but how can I add the
DMZ? I will only have 2 systems on that segment, but it needs to be
completely free of the policies on the firewall. If any of this needs
clarification, please let me know. I greatly greatly appreciate any
response...
TIA,
Chad
