Check out "Internet Junkbuster"
(http://www.junkbusters.com). It's a web proxy that you can
configure to block certain sites and it works well in
linux. While you'll still have to feed it a list of sites
it may be nicer than your ipforwarding method.

Does the 486 machine have only ISA slots? ISA can't keep up with a 100
Mbps network so you might be better off just going with a 10 Mbps ISA
card. Check the http://howto.linuxberg.com/LDP/HOWTO/Ethernet-HOWTO.html
for a detailed list of various cards.

Ahh, but did you also change ppp from the version that came with 2.0.36
to the version that goes with 2.2.9? They're not compatible with the
opposite version kernels.

No! Without the quotes, as I said in a reply to me. I never claimed to
be a guru, but what works, works, and those quotes were there when I
called it up to compose that reply, and I stupidly clicked on accept, at
which point my ppp0 fell over and refused to connect. I took 'em out,
and instant gratification again.

Agreed. :-)

I did manage to find a somewhat fuzzy explanation someplace in the
HOWTO's, AFTER I figured out how to make ns4.51 load a local file.

Well, my problem turned out to be an interrupt conflict on the modem.
If you see a long delay in the log between a modem command and the
response, that may be your problem as well.

I would like to disable tcp_window_scaling on my RH 6.0 box in the hopes
that this will make it communicate better with my MS NT 4.0 box.
How do I change one of the settings in /proc/cyc/net/ipv4? My first

2 solutions:
I. Edit Windows registry to enable the plain text password;
Procedure:
1) Launch the Registry Editor as follows:
Click on: /Start/Run
Type "regedit" and press enter.
2) Double click on: HKEY_LOCAL_MACHINE
3) Locate the following Key:
/HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/VxD/VNETSUP
4) From the menu bar select Edit/New/DWORD Value
5) Rename the entry from "New Value #1" to:
EnablePlainTextPassword
6) Press Enter, then double click on the new entry.
A dialog box will pop up and enable you to set a value.
You must set this value to 1.
II. Using encry. password in Samba : Look at the ENCRYPTION file that comes
with the SAMBA.

Please forget the single quotes, when I brought it up to give it to you,

Hello,
I just installed Red Hat 5.2. I have a 3Com 3c509 Ethernet card in
it. Linux sees the card just fine but I cannot ping the machine or
out from the machine. All my other machines are fine.
When I type ifconfig, this is what I get:
eth0 Link encap:Ethernet HWaddr 00:10:4B:24:EA:8E
inet addr:192.168.10.11 Bcast:192.168.10.255

Anyhow, a friend suggested trying TCPDUMP. I looked and it is not
installed.....but it is on the CD. how do I install it?
I am looking for help trying to get this NIC to work.,....if you have
any suggestions, please let me know.

Subject: Cannot ping other win95 PCs in same LAN segment
Date: Mon, 24 May 1999 12:50:05 +0800
Reply-To: [EMAIL PROTECTED]
Hi all,
I currently have 3 PCs that run on Win 95. These 3 PCs are linked thru
private LAN that I set up using network cards and a hub.
The IP address for the PCs are 192.1.1.30, 192.1.1.40 and 192.1.1.50.
The netmask for the LAN segment is 255.255.255.0 and the domain is
'iceberg'.
What I want to do is, to set up a REDHAT Linux 5.1
in a new PC in the LAN segment and have 192.1.1.60 for IP address,
so that all the 3 PCs running Win95 can telnet and login to the linux
server.
What I did so far, was get a book called " LINUX SECRETS" by Naba
Barkakati
which comes with a RedHat 5.1 distribution CD-ROM. Then I followed the
instruction in the book on installing the OS on a new PC
with a 3com 3C905B network card.
I answered Y to " Do you want to configure LAN...?"
and put in the following info for the next dialog box.
IP adderess : 192.1.1.60
Net Mask : 255.255.255.0
Default Gateway : 192.1.1.254
Primary Nameserver : 192.1.1.1
For "Default Gateway" and "Primary Nameserver", I left it to their
default value
eventhough I don't have any machines with IP address 192.1.1.254 and
192.1.1.1 on
my network.
For the next dialog box I keyed in these info,
Domain Name : Iceberg
Host Name : Captain. Iceberg
Secondary Nameserver (IP) : <blank>
Terting Nameserver (IP) : <blank>
Then, the next dialog box is the time zone setting and after
that I got dialog box asking "What services should be automatically
started?"
I did not change any default setting on it but instead went on
and cliked 'OK'. I skipped all the printer-setup dialog boxes and
followed
all the instructions regarding the LILO that made sense to me and then
it was done.
So, I reboot the machine and logged in as root.
The first thing I did was ping the linux own IP address
which was 192.1.1.60. Yes! It worked.
But when I ping the IP address of all the Win 95 machine
it was just not there. And when I ping the Linux IP from any one
of the Win 95 machines, the same thing happened. The ping failed!
So, if anybody out there can help diagnose my problem please reply.
I've already tried everything I know which is not much by the way!
So any response would be greatly appreciated.

Can anyone point me to how to set up MSChap to an NT RAS server, but
using the standard configuration tools of RH6.0? I'd rather stay
within those bounds so I can use RH's interface for configuration
as well as opening & closing the interface.
