Hi, I'm wanting to do some testing with my linux (RH5.2) box. I've been
playing with ipfwadm and tranparent proxying. The problem is this, I have
only the one box. The transparent proxying only works when data arrives on
my box and goes into the input filters. When I try to test Netscape with the
transparent proxy it appears to put data on the output queue, so there is no
tranparent proxy. What I'd like to do is buy another PC and connect it to
this on, but I can't afford that. So I though I might try the news groups.
My idea was to create some sort of bogus interface (logic0) or some such,
then try and get netscape to send it's traffic to this interface there by
sending all my traffic through my firewall filters and tranparent proxy
stuff. Does anyone know if this is possible? I looked into chinging the
routing but I suspect there is no real way of sending all traffic back into
my box and then out to where it's supposed to go after it is filtered.
Any ideas would be greatly appreciated :-)

You are going to need a good sized chunk of a T1 just for the news
feed. If you're running with something slower than a T1 don't even
think about a full feed. If you don't get the alt.* hierarchy you can
still do the feed with a slower link. The linux doc projects how-to
list is probably the best place to start. Then read the documentation
for whatever news servers you are thinking of as a possibility. The
linux doc project's how-to list is here

There is also another workaround, changing a Linux configuration file instead
of changing the Win98 registry. Check the howto's for more info.

Hi, I posted this yesterday, but I didn't see it arrive on the list so here
it is again (apologies if it made it to you). I want to test some
firewalling stuff I'm configuring with only 1 machine. This means I have to
create an interface (eg bogus0) and get an application to send traffic
'apparently' from it to the box I'm testing on. Can this be done? Is there
any code out there that will do this or something similar.
Thanks in lieu :-)

Can anybody recommend some good sources of information for networking
programming? Such as, where would one get copies of the various RFCs
for FTP, HTTP protocols etc.
Specifically, I'd like to find out the protocol details for ftp'ing a
file through a proxy server.

Just installed RedHat 5.2 and can connect to my ISP, but can't ping anything
out on the Net. It seems that my ethernet card is setup as the default

How do I set ppp0 as the default? I know I did it on my 4.1 installation,

I am not sure how you are configured, but I use sendmail, and it doesn't use
these files. These files are only used by the wrapper program. So in
general these are connections in the inetd.conf. I would suspect that you
don't have an smtp line in here. A better bet would be that either you or
the hacker did something to stop sendmail from running properly. Check the
maillog files. Also try manually starting sendmail, it may be giving an
error message that you are not paying attention to because it is being
scrolled off the screen during boot up.

I have a pentium pc running RH 5.2, X and Star Office. I want to ethernet
connect a 486 workstation running X (or as a "remote" X terminal) and
sharing Star Office, data files stored on the pentium and the printer
connected to the pentium.
Is a non-dedicated server network like this possible in Linux? Roughly what
are the packages I need installed on the workstation and the server to do
all this?

Yep. Under windows this is com 1 so that would be /dev/ttySO.
There is the Lucent modem on com2 /dev/ttyS1. This is an internal modem.
I really can't figure out why I can't get the modem to work. When I run
minicom it says there is no such file or dir /dev/modem, but the file is
there.

You have a few more steps to follow before your NFS server gets going, which are
as under :-
1. On your NFS server make sure that in file /etc/inetd the rows with bootpd and
tftpd are uncommented.
2. Edit /etc/bootptab file and make entries for all the diskless hosts you want
to run. You should consult /usr/doc/NFS* and /usr/doc/NET3* files for detailed
info about how to do it. I can meanwhile repost a detailed procedure about how
exactly to do it if you need.
Do not forget to give command bootpef after any changes you make to this file.
3. Put boot ROMs on every ethernet card of diskless hosts. The boot file should
contain the driver for your network card and tftp client which takes care of
initial call on the network and bootp client which requests server to actually
mount the NFS. The package which enables this is
http://metalab.unc.edu/pub/Linux/system/boot/ethernet/etherboot-4.0.tar.gz.
OR
Just make use of
http://metalab.unc.edu/pub/Linux/system/boot/ethernet/diskless package to boot
off a floppy drive on a diskless host.
4. Create a directory which is actually mounted by a diskless host once it boots
off in step 3 above.
Generally the directory is named /tftpboot with its subdirectories as
/tftpboot/192.168.0.1, /tftpboot/192.168.0.2, ... for the very obvious reasons.
You will have to creat a skeleton file system
on each of these subdirectories, similar to our Linux root '/' filesystem, which
will hold the image for the remote filesystem.
5. Configure the files in /tftpboot/192.168.0.?/etc for each host to hold the
host specific configurations.
6. Edit /etc/exports file to export any file systems you like to share with other
hosts. Do not forget to give command exportfs -a after any changes you make to
this file. And do edit fstab for every host
entry in /tftpboot directory to mount any NFS file system over a remote host.
Don't worry I also faced the above seemingly groovy stuff, but it is worth while
once you have
X-Windows over NFS running on diskless machines.
Do study the help files and documentation for Linux before you do all this. It
would be a great help.
With Best Wishes!!!

I'm not exactly sure what your symptoms are -- but when I was first setting up
a pcmcia ethernet card (3c589d) on a SuSE system [Using the pcmcia module built
from source as the version that comes with SuSE doesn't have support for the
Toshiba controller] I had problems getting it to see the netowork because the
YAST network configuration doesn't set up the pcmcia files. I had to manually
set up /etc/pcmcia/network.opts -- the pcmcia with RH on the otherhand has been
tweaked to use the standard network config files.

Well I'm not sure about the novel, or even the windows parts because most of
these positions linux is usually the server; however, you could just make the
users once on one machine, pass the /etc/passwd file to all machines, and have
them all mount their home directories from an nfs mount.hope that helps

Subject: ne2000 clone help?
Date: Thu, 14 Jan 1999 06:48:01 GMT
Hi everyone,
I have an old 486/66 that I would like to use as a fire-wall and
I've been stumped ! Perhaps someone out there is gracious enough
to help.
The problem is as follows:
I have a cheap ne2000 clone (SN-2000 ISA card matter of fact) that
works in a friend's 486/66 running redhat 5.1.
When I put it in my 486/66 running redhat 5.2, no matter what I
try the card is not detected.
I've gone through the Ethernet-HOW-TO and tried a good portion
of the suggestions in the HOWTO.
Such as:
1 making sure the /proc/ioports are not close to the base io
address of the card (tried many different base io address
for that matter)
2 making sure the /proc/interrupts isn't being clobbered.
3 recompiling the kernal with the ne card support ONLY.
4 specifying the irq,and the base io port address during
the boot.
Given these facts, I suspect that it might be the motherboard and
the bios setting. Could this be it ? If so, how do I fix this
turkey?
The bios for my 486 is (ROM ISA BIOS I486SV2G) from award software
and the irq settings sez:
IO DEVICE Timer: Disable
IRQ1,3,4,12: IRQ's
COM/LPT Ports: COM
IRQ15 (Reserved): Enable
IRQ14 (Hard DIsk): Enable
IRQ13 (Coprocessor): Enable
IRQ12 (PS2 mouse): Enable
IRQ11 (Reserved): Enable
IRQ10 (Reserved): Enable
IRQ9 (Reserved): Enable
IRQ7 (LPT or LAN): Enable
IRQ6 (Floppy Disk): Enable
IRQ5 (LPT or Lan): Enable
IRQ4 (COM 1): Enable
IRQ3 (COM 2): Enable
IRQ1 (Keyboard) Enable
Note that the irq toggles are Enable/Disable only. I've also
tried several combination of Enabling and Disabling the irq's
for the card as well.
I've also tried to Disable IRQ 7 and 5 in case they
were conflicting with the card.
If someone out there could help, I would definitely appreciate it!
Thanks in advance.
Best Regards,
Kirby Kim.
