Ha! It works! Thanks, Clifford..
And for the rest of you, I'd thought I'd tell you how I go about shutting
down my firewall and SMB server remotely.
telnet from Win95 machine to SMB server
login as normal user (ie not root)
type su -
type password
type dip -t
port /dev/ttyS0 <-- firewall is connected to SMB via null modem cable
speed 38400
term
(now logged into firewall)
login root <--- BTW, Clifford, is this correct? Normal user wont work
here...
type password
type shutdown -h now
(firewall begins shutdown)
reconnect telnet to SMB server
login as normal user (ie not root)
su root
type password
shutdown -h now
(SMB server begins shutdown)
All done.. power cut to home network...
Thanks again, Clifford...

Please read the manpages for rlogin, rhost. There you find
information about the files /etc/hosts.allow and ~/.rhosts.
On the machine you try to rlogin there must be an entry in /etc/hosts.allow
for your machine. In your home directory on both machines edit .rhosts
to look something like this:
linuxbox [user]
If user is omitted you have to have the same username on both machines.
What should work is telnet -l user hostname.
Then you have only to know a valid user and password on the destination
machine.
Hope it helps.

I just installed RedHat 6.0 and configured my @home cable modem(with intel
etherexpress pro pnp card). I can type ping and ping my own IP and I get
responses so that means that something is working. Unfortunately, when I
use Netscape(in Gnome) it appears as though it would load the page, but
rather netscape just sits there idly with a Looking up hostname...... thing
in the bottom of the window. Also, when I try to use IRC or log onto FTPs,
nothing happens. But I am able to ping myself, so what's wrong?!

You haven't set your route properly. The packets are probably going
out but not coming back in.
Logon as root and type 'netcfg'. Click on routing and add your info.
You might have to deactivate and activate your eth0 again.

Date: Mon, 16 Aug 1999 02:30:47 GMT
I have tried to get it work but no matter how it does'nt seems to.
After downloaded from RealTek's homepage the linux text i tried to follow
it.So 1-The kernel is recompiled with (*)module support,(*)networking
support,(*)network device support,(*)ethernet and (*)ne2000/ne1000
(/usr/src/linux make xconfig which i believe is the same as make
menuconfig)
2-Run make dep,make clean,make bzImage (I boot to the linux RedHat 6.0 with
a boot diskette.In the original linux.txt stands make zImage which i
believe should be make bzImage.zImage comes with some errors anyway if i
try it.)After copying bzImage to the boot diskette i boot with that and try
to st up an ethernet device (eth0)and i am sure i do it the right way.
But when i try to activate it from usernet it never get the green color.
If i boot with it i get the message "delaying eth0 initialisation"
I know that there are two ways of doing it (getting ne2000 driver):with
configuring the kernel (as subscribed above)answering "Y" that make it a
part of the kernel or answering "M" which make it a module that should be
loaded to the kernel.The linux.txt from realtek's seems to use the first
way.I don't know what i am doing wrong.From the linux.txt document "the
driver will be loaded and will scan 0x300,0x280,0x320,0x340,0x360 port to
see if card is there. but from windoze i have the following RTL8018PnP Lan
with Input/Output 0220-023F and IRQ 05."How can i see that the driver is
loaded?I cannot see any after i run "dmesg" to see the boot message.
as a p.s in the linux.txt "in some case , PNPISA may assign io ports not in
range you can use 'rset8019' (in DOS) to set the card in jumpless mode ,
ioport" Well i have tried to do this from linux with dosemulator but i
can't.How exactly should i run it from DOS.I have not the real DOS
installed.I have windoze98,windozeNT4.0 workstation,and linux RedHat 6.0
running on the same P.C.
Any suggestion and help is welcomed.I am really in the dark here.
thanks a lot.

But be careful if you're running any sort of DNS, because I've
heard no end of trouble with people getting spurious dials in
that circumstance. I'm running caching nameserver, so I haven't
even tried. Besides, the rest of the family appreciates some

I'm trying to get PPP going on my new Slackware 4.0 setup.
I've been using PPP for several years on my older linux stuff with
little incident but now... For some reason, I can't seem to get past
the successful login of userid and password. All I get is some stuff
about LCP confreqs timing out or something to that effect. I am using
the default scripts provided with Slackware 4.0 using kernel version
2.2.6 and PPP 2.3 (I think). Keep in mind the chat script is working
fine; it gets through the modem setup and login and password prompts
with no problem but I never get the IP address from Primenet.com. When
I used the debug option in my ppp options, I see that it is exchanging
LPC messages but the number of sent far out numbers the ones received.
I don't think this is right. The internals of PPP go over my head a
bit and I don't really know what to do beyond this point. I guess I
could recompile PPP and the kernel and see what that might do for me.
Oh, I am using the ppp-go script provided by the slackward
distribution with no local changes.
Can anyone help me out with this one?

Subject: Help trying to setup masquerading for PPTP
Date: Mon, 16 Aug 1999 02:45:49 GMT
Hello,
I have a Windows 98 box sitting behind a Linux firewall. I'm trying to
understand how to set up PPTP connection from my Win98 box to an external
server. I have RedHat 6.0 (kernel 2.2.5) and have IP masquerading working
fine.
Looking through documentation on the web, I'm getting confused. If I
understand it, ipportfw and ipfwadm have been replaced in 2.2.x kernels with
ipmasqadm. However, all the pages that I find that talk about VPN setup
discuss ipportfw and ipfwadm.
Is it possible to setup PPTP VPN with ipmasqadm and ipchains alone?
Any help would be appreciated,
Thanks
Peter

Hi,
It seems you didn't have a correct dns setup. You have to create a file
called /etc/resolv.conf which should have the nameservers' ip address
something like this:
nameserver 192.168.1.2
Also, you need another file /etc/host.conf which tells your system how
to make name lookup. The relevant line is
order hosts,bind
Of course, for this to make sense, you would need an /etc/hosts file. I
would recommend check out the NAG, Linux Network Administrator's Guide.
It is available either as book or online (LDP, possibly on your machine
if you installed the docs). It is a gentle intro how to setup a network
and some network related config.

Date: Sun, 15 Aug 1999 20:11:59 -0700
Hello,
With network of your size you should not worry about subnetting. Just make
sure that your network backbone is switched (switches are linked!), server
should be connected via switch as well, and give each workgroup a switched
down link.
If you need to manage the bandwith in your switched network, you can learn
more about VLANs (virtual LANs).
Actually more and more networks everyday are moving from router based
networks to switched networks with VLANs.
Good luck!

Subject: delaying eth1 initialization
Date: Mon, 16 Aug 1999 03:57:04 GMT
I cannot seem to get a second card recognized which is a ISA NE2000
compatible with a realtek8019 chipset. My first card is also an ne2000
compatible D-Link card.
I upgraded to the 2.2.11 kernel (and also had to change to ISC's dhcp
client). But the DHCP address is really only for eth0.
cards are configured as follows:
eth0 interrupt=3, io=0x300
eth1 interrupt=5, io=0x320
I previously tried interrupt=9 and 0x280 but same problem. I did check that
there are no io conflicts.
On bootup I get:
NE*000 ethercard probe at 0x300: xx xx xx xx xx xx
eth0: NE2000 found at 0x300, using IRQ 3.
But no mention of eth1.
then later I get
"Delaying eth1 initialization"
questions
1) Any idea why on startup it can't see any detection of eth1? I read in
redhat linux secrets that it does not detect multiple cards. How can I
remedy this? When I pull out the eth0 card it _does_ detect the eth1 card.
2)Any idea how I can get second card talking IP?
Thanks in advance for your help

You want to take a look at the HOWTOs dealing with
firewalls, IP masquerading. Ethernet, IPChains, ISP Hookup,
Net-3 and Networking. that's alot of stuff but in effect
you need to set tour Linux system up to be a
router/gateway. The firewall adn IP Masq. should give you a
good start.

You aren't getting DNS. Trying pinging by IP, I bet it works..
When you ping yourself you are only pinging the loopback address, so this is
not a real test.
