Good. Are you using both an IP filter and an application filter? Such as

Hummm . . . This is a interesting way of doing things. This means you have
to have setup some special static routes on your Linux firewall.

You won't be able to ping unless IP forwarding is on and you have some
ARP and static route statements added to the firewall. What you are
attempting is NOT a good idea. The machines that share the same hub as
your firewall are vulnerable to outside influences such as crackers and
other malcontents. I suggest either re-IPing your inside boxes to private
numbers (10.0.0.0/8) and use the valid IP addresses only on the outside
of your firewall or have your ISP give you another block of 32 to use on
the outside of the firewall.

Right! You have no ARP and static route statements to accompany the
IP_FORWARD. Think of it this way. How does the one NIC know to listen
for packets destined for the other NIC if you don't tell it to?

I strongly recommend using a proxy filter as well (TIS fwtk, Squid, or
SOCKS).

The statement you have above is correct. IP forwarding is on. That is
not your issue. Your issue is static routes and ARP statements. Read up
on them.

No. Once you go to different IP blocks on each NIC this issue will go
away.

Nope. Read above.

I am interested in getting a cable modem internet connection through the
local cable provider here in Baltimore, Comcast. However, there is more
than one computer in the house, and if we want all of them to be wired to
the cable modem, we need to setup a network. Here is my question: What all
is involved in that? I'm a computer science major, so I've got a pretty
decent understanding of the concpets, and all, but I've never setup a
network. Here is what I *think* is involved, please tell me if I'm right
or way off:
We buy a hub which hooks into the cable modem. The modem acts sort of as a
"server", to which each of the computers is connected as clients. Network
cards (ethernet I believe) run into the hub connecting each of the
computers.
Is this right? Has anyone had experience with this type of connection who
could lend me a hand with it? Instructions? Hardware/Software
reccomendations? Any help you can give would be REALLY appreciated!
Also, I'm running Windows 98, Linux, and Solaris on my computer. Can I use
the cable modem connection with Linux and Solaris?

Hello people. Thank you for your attention.
I've to make SAMBA server running for small department.
NT PDC (effectively only authentification) + Samba (workhorse - disk space,
backup, printing, etc). All goes fine except I can't figure out meaning of
"Printers" folder. When I have shared printers NT WS connects to Samba
server and sees printers and empty "Printers" folder, When I remove all
shared printers I've only empty folder, if I remove all including [printers]
section I still have this folder. Nearly same goes when I share printers
from NT server. So question, what for do I need this "printers" folder.
F.e. Mars NWE doesn't show such folder. Could I remove it somehow? Actually
I don't care it can stay (security?) and I forgot how to wonder about M$
masterpices but what for did they introduced this folder?

Is there any documentation on nsupdate? I can find the utility but there
is no man page or docs anywhere I can find. The DNS-HOWTO doesn't mention
it either. Hell, if this works one of my biggest problems with DHCP and
DNS may just be solved!

Just set up the 2 connections normally. But you will need to alter=20
resolv.conf for each so they use proper nameservers. You can do this=20
from /etc/ppp/ip-up and ip-down (or *.local in RedHat). Not sure if=20
you need to alter your hostname, but I never have even when connecting=20
to CompuServe with dynamic IP. In ip-down.local I similarly 'cp=20

Our apartment complex is offering T1 access in our apartments
for a certain monthly fee. For the basic fee we receive a
dynamic IP address. For an additional fee we can receive a
static IP address.
What I am interested in doing is mounting several file systems
from my office workstation (a Sun Ultra 2 running Solaris) on
my Linux box via NFS. Can this be done if I have a dynamic
IP address? I'd rather not pay the additional monthly fee for
the static address, if possible.
The mini-HOWTO on DHCP seems rather sparse--I'm not sure if
this is the answer to my problem. I'm running RedHat 4.2 with
the 2.0.18 kernel version.
Thanks for any info,

It could be that the unix box has a /hosts/allow arrangement allowing

It looks to me like the driver is having trouble talking to the
card. The message indicates that the driver is waiting for a
"Remote Dma Complete" response from the card after it
has told it to send the packet. Could be that the card is not really
NE2000 compatable. W/ PCI I would think the driver would
find the correct I/O & IRQ values, but maybe not:? I'd also check
your cables & make sure the link light is on on you hub.
Good luck.

Is this a monolithic kernel or a modularized kernel. If it is modularized,
you can type something like "linux init=1" at the lilo prompt to get it to
boot into linux single user mode and make your changes there, it shouldn't
load any of the modules. Perhaps even init=2 would work, since that is
multiuser w/o networking. You could try this with a monolithic kernel, but
I am not sure it will work. Regardless, you could always try to umount the
boot floppy and mount a dosfloppy with a correct copy of the kernel on
it. I am not too sure that the floppy kernel would support a dos formatted
floppy, but it is worth a shot. Obviously, if you can get at a unix box and
create the file you want from there and remount a floppy with that, it should
work. Hope this helps

Check out http://simmons.starkville.ms.us/tips/081797/ for more
information.
Basically, you need to have the allow-update option set in the zone for
which you want to permit updates.
Also check out http://www.acmebw.com/askmrdns and search for nsupdate.
The commands are as follow:
update add <hostname.yourdomain.com.> <ttl> IN A <ip address>
update delete <hostname.yourdomain.com.>
and can be given on the command line or in command file.
There's also a PERL package that wraps the nsupdate command. Check out
http://www.fuhr.net/~mfhur/perldns/Update.html.
Finally, don't forget to look at www.freshmeat.net's appindex for the
cron script that will parse the dhcp.leases file. (once www.freshmeat.net
is back up, that is)
