I'm not 100% sure I understand what's going on here, but true to
myself, I will speak anyway.. :()
If you have a firewall set up and the audio server is going to be
outside of it, and you give that server a local IP, you'll have to
open the firewall to accept local IPs on its EXTERNAL interface. No
big problem with this, in a technical sense, I guess. The problem
that I see is that you'd be opening yourself to IP spoofing attacks by
allowing "internal" IP addresses into the firewall from the outside.

I think he said he did that already. I've had, actually I still have
that kind of problem each time I do a fresh install of rh60. Are you
by any chance using a netgear NIC? After rerunning netconf and
dinking aroud with the settings (delete & re-enter :-)) and a couple
of reboots, the thing would then work. Been bugging me for a while
now.

Does the ISP even have the time to scan and log all this stuff, and
why would they bother unless there is a huge surge in bandwidth?
Otherwise what would they be protecting themselves against? If they go
to all this trouble and then shut you off, there goes their monthly
income stream from you and all the other poor fools they waste the
time and effort on to sell you on their service, set it up and then
kick you off. Seems kind of pointless. It would be like a drug pusher
selling you drugs, getting you hooked and then turning you into the
police, thus killing the goose that laid the golden egg.
Hey, I guess if I lived/worked in an apartment complex/office bulding
I could subscribe to a DSL service, wire up the complex with
ethernet, run ip-masq, set up my own apartment complex/office building
isp and sell the service to all the occupants. That would probably
piss the DSL provider off, eh?

Subject: General Sendmail Question
Date: Thu, 26 Aug 1999 17:31:01 GMT
I have set up a mail server using RH6 (also serves as my workstation) that
is able to send and receive email through the internet.
I would like to do is move this box to only perform email/web/ftp server
functions and then set up a new box for personal use. That way I can
screw around all I want with "my" box without messing with the server
services.
My questions:
1) Do I just continue to leave mail on the server and pick it up via POP
or IMAP?
2) If I don't pick the mail up with POP, can the mail server just deliver
it to my machine automatically? Where can I be pointed to for
reconfiguring this?
3) When I create mail on my machine, does my machine send it out directly
to the internet, or does it get routed to my mail server for for ultimated
delivery? I like to use KMail for mail reading/creation.
4) If I have to send outbound internet mail to my mail server for
delivery, what file needs to be configured?
5) What mail related services need to be running on a workstation?
Thanks for any help. I am planning to buy the O'Reilly book on sendmail
to get an idea how all of this is supposed to work. I have heard that the
book does not include some of the latest updates/features though.

Date: Thu, 26 Aug 1999 20:08:18 GMT
Actually the problem was that I didn't have ipchains installed on my
computer. I thought it was installed with RH 6.0, but it wasn't.
Support for ipchains came preinstalled on the kernal, but the ipchains
program wasn't installed by the RH installation. I downloaded
ipchains, compiled it and everything works great, including the
newsreader.
The ipchains program was called several times in the rc.firewall
script, but wasn't actually there, so things weren't working properly.
I was able to get Netscape to work by enabling the proxy config and
pointing it to the linux box, but one I got ip-masq working with
ipchains the proxy wasn't even necessary.
There wasn't anything in any of the documentation I read about
masquerading nntp. How would you do that exactly?

Hmm, that didnt work for me, but what i did was i went into the ftp

I did modprobe ip_masq_ftp as well, but before the firewall setting and
it didnt work, so maybe it was a combination of the two that fixed it.

In modern distributions like Red Hat and SuSE, Tcl/Tk comes on the CDs.
There is some documentation included, but a good book you could try is
called "Tcl and the Tk toolkit" by John Ousterhout.
(He's the creator of tcl/tk).
As well as some good tutorials since I've never even seen

Search your Mandrake CDROM. There should be 2 versions of tcl/tk included.
The old 7.6 one and the new 8.x version...

Is there any way of seeing the rest of the network from Windows? Thanks

Hi,
I have the same setup in my PPC7500.
If you are not sure about what ethernetcard you have have a look in
/proc/pci and /proc/interrups
You must recompile your kernel with the DECchip Tulip (dc21x4x) PCI support
as a module.
Then you must edit your /etc/conf.modules, I have added in my
/etc/conf.modules :
# installing ethernetcards
alias eth0 mace
alias eth1 tulip
options eth0 -o mace io=0x100 irq=14
options eth1 -o eth1 tulip io=0x400 irq=25
It's working fine under LinuxPPC R5 and in past also on R4.
Succes,

Simon,
Masquerading is included in the kernel and masquerading is working fine.
I just use one ipchains rule to enable the masq functionality.
ipchains -A forward -j MASQ -s 192.168.0.0/24 -d 0.0.0.0/0
That is why I am fustrated when phonepatch at port 1084 and fsgs at port
6112 don't work..
Anyways, thanks for your reply Simon.

The netgear card works flawlessly in WinX though. I've also had that

What about port-forwarding? While I don't know the details, I do know
that you can enable port-forwarding so that requests (like FTP, for
example) that arrive at the firewall's ports can be sent on to the
appropriate host within the local network.

Samba can be used, but for DOS, I think this would be difficult. Your
best option would be to get a good NFS client for DOS and use that. This
provides remote disk access as a drive on your DOS machine. Now where
you would get one, I just don't know. Try www.download.com or a search
engine like yahoo.
To do Samba <-> DOS, you need the netbios installed and running. I
have never done this, but I believe that windows 3.11 for workgroups had
this builtin and would solve that problem. Next make sure you Samba
server is configured correctly. This, however, is another problem and
can be solved by reading the docs and searching the myriad of Samba help
sites around the world.
Good Luck.

Okay.. here's a brief ASCII art picture.
[W98_PC3]
| 192.168.2.0
|
[NT_PC1]-------[W98_PC2]----[LINUX_SV1]----129.215.x.x---> To
Net
|
| 192.168.3.0
[LINUX_SV2]
|
| 192.168.1.0
[w98_PC4]
Okay, as you can see I have 4 PCs which need networking. Three Win 98
machines and one NT machine. I have TCP/IP routing just fine. As
you can tell, I had to use Masquerading on LINUX_SV1 to get the W98
machines on the branches to see the net.
Okay, what are my problems:-
1) The W98_PC2 sees NT_PC1 as the Domain Master, but all the other
machines think that LINUX_SV1 is the Domain Master. How do I
stop the NT machine from grabbing the domain?
2) Then I do SMBCLIENT -L W98_PC3 from LINUX_SV1 I get:-
Interface added 192.168.2.1 with netmase 255.255.255.0
session request to W98_PC3 failed
session request to *SMBSERVER failed
3) How can I get all 4 computers in the Mygroup domain to all appear on
their browse lists?
W98_PC2 sees : NT_PC1 itself LINUX_SV1
W98_PC3 sees : LINUX_SV1 LINUX_SV2 itself
W98_PC4 sees : LINUX_SV1 LINNUX_SV2 itself
LINUX_SV1 sees: itself LINUX_SV2
LINUX_SV2 sees: LINUX_SV1 W98_PC4 itself
(in short, they see their own little corner of this horrific
network)
Can anyone point me in directions where I can fix these problems, or at
least find out how to diagnose what's going wrong? I've been all over
the net, and I've checked this newsgroup, and haven't seen anything
similar.
Many Thanks in advance
Nick

The above means you've got an irq conflict. cat /proc/interrupts will
show you the irqs in use and one is likely an irq that the nic needs.
I just took a quick scan through the Ethernet-HOWTO and couldn't help
but notice all the tips and tricks aimed squarely at the 509.
