Subject: Linux 2.2 firewall, logging rejected traffic?
Date: 26 Feb 1999 16:04:29 +0200
I'm running a firewall/proxy machine with Linux 2.2 kernel. I would
like the system to log all traffic the IPCHAINS rules reject, but I
don't really care about the traffic that is accepted. Is there a
program that I could use to log the rejected packets, and preferably
analyse for attack patterns and warn me if anything is detected?
Please Cc me in your followups..

Pppd-2.3.5 supports demand dialing. Diald is said to be more
configurable.

This does not give me a warm fuzzy feeling here. The initial freeze was
most
likely do to an incorrect hosts file or entry therein. This problem
probably
still exists.

Absolutely ..... fix your system. It seems to be suffering from an
indentity
crisis. I would also suggest reading up on IP Networking, some further
knowlage in this area could have prevented this perhaps....
You could try posting the contents of /etc/hosts if none of this makes
sense.

Subject: domain with remote hosts
Date: Sat, 27 Feb 1999 15:05:44 GMT
I have a friend with a cool domain and a good job. She can afford a leased
line and a domain and I can't. I dialup to my ISP and what we want to do
seems simple, but I'm not exactly sure how to do it. I want my RH5 system to
be a host on her domain (she has FreeBSD).
ie. she is (lets say) thinker.blah.net
I want to be einstein.blah.net
I have a static IP address from my ISP, but it is not on the same Class-C as
her's. We can probably talk to the ISP and get our IP's on the same Class-C
if that would do it.
Could anyone please give me some insight into what has to be done.
Thanks

Subject: Trouble with IP tunneling under Linux (Red Hat 5.0)
Date: Fri, 26 Feb 1999 10:02:51 -0500
I'm trying to set up IP tunneling to be used over the Internet. On one
end is our Linux box that's connected to the internet and acting as our
firewall, DNS, mail server, and also does IP masquerading. In our
initial testing, we're using a Linux box at a coworker's home which is
part of a LAN there. So far, we've not had any luck getting the two
networks to talk to one another.
We've read the IP tunneling README file, and tried to set our up in the
fashion outlined there. However, I'm wondering if the firewall and IP
masquerading makes it more complicated than what's in the README.
First, if anyone knows of a source of more in-depth documentation for
setting up IP tunneling on Linux, please let me know. Also, I'm
wondering if Linux will have to be on both sides, or with this work with
Linux on our end, and HP-UX on the other?
Should the IP number used for the "ghost host" be an IP number from our
IP numbers on the outside of the firewall (i.e., those IP numbers that
are actually valid, registered numbers), or can it be an IP number from
inside our firewall?
Thanks.

Sorry about the brevity of my reply but I've had a problem with posting
the long version with comments. The answer is in the excessive time
differences between the commands sent to the modem and the modem's
response to those commands.
There's really only one conclusion: The IRQ configured for the modem
device file, /dev/ttySx x=integer appropriate for the modem, is not
the IRQ actually used by the modem.
The IRQ is configured for the device file by setserial at boot time,
usually in one of the /etc/rc.* files. Find out what IRQ the modem
actually uses and configure this one for the device file.

When I set up redhat 5.2 at home I had a NT 4 dhcp server. No I dont have
dhcp, but every time linux boots it searches for a dhcp server. When it is
done I end up assigning it an ip using ifconfig.
How can I disable the dhcp search on boot and establish a permanent IP.

you do not need a static IP for your own domain; your ISP should be able
to set up a "blind forward" such that all traffic to your.domain will
get forwarded to your ISP account. When I set my domain up back in '97,
it cost $50.00 for the setup fee and $50.00/year, with a 2 year
minimum. My ISP (mindspring) handled the "work" in dealing with the
Internic; it was worth the $$ for them to do that.

Keith,
Samba will do exactly what you're looking for. It will act as a PDC for
Win95/98 clients. Read the documentation on SMB.CONF (man smb.conf).
You'll want to enable "domain logons = yes". You can have roaming
profiles, logon scripts, home directories, etc. - just like NT, but cheaper
and faster (not just OS $, but faster than NT on slower hardware). You
mention an intranet server -- of course, Linux runs the Apache web server
quite nicely as well.
I use a single Linux box at work as a print server (via Samba) for 400
Windows NT workstations printing to 20 printers. I also use a separate box
as a web server. These boxes have been up for months without a reboot -
which can't be said for my NT PDC!
I hope this helps ... email me if you need help with the Samba settings.

SAMBA or NIS?

Very common. It involves not having your DNS set up correctly, or not
having all your hosts defined in the /etc/hosts file. I think someone
ought to write a FAQ about this...Anyone?

Windows 98 will allow for password encryption but 95 will not. Try this :
on your Windows machine (works on 98 too) ,regedit
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Vxd\VNETSUP]
new dword
"EnablePlainTextPassword" = dword:00000001
Don't use the quotes,of course.
Reboot.
This worked for me.
