A network expert is able to do whatever he wants on your machine when you
are directly connected to his computer... The only problem is to convince
the lawyers using legal methods. I don't think it is legal to forbid
masquerading, and your computer only acts as a gateway. For a non expert,
the sole thing which can help to find whether or not you are masquerading is
the heavy traffic on the network connexion, coming from many sites at once.

It is the normal way to kill pppd (often by scripts) for

Subject: IPX Router
Date: Wed, 01 Sep 1999 00:31:07 GMT
I am setting up a linux router for the high school in my school district.
It it is connected to the WAN via tokenring. It connect two diffrent
ethernet segments together to the tokenring and does pass tcp/ip very
well. I am having a problems getting ipx to work on the token ring as a
tokenring ipx router. the two ethernet segments work with each other and
is passing ipx. I have added the folowing to my inittab file to deal with
ipx.
ipx1:3:once:ipx_interface add -p tr0 802.2 a0200
ipx2:3:once:ipx_interface add eth0 802.2 4326634
1px3:3:once:ipx_interface add eth1 802.2 4343675
ipx4:3:once:ipx_internal_net add a0400 43643264
ipx5:3:once:/usr/sbin/ipxd -d
The techies have told me that the tokenrings address ipx node is a0400.
I have no clue what the proglem is...
Thanks Dan

If the router, fileserver, web server, nameserver is in any way a
small machine, I suspect you are running out of cycles. You have the
symptoms of "sure it will run everything, it's Linux!" disease.
You *may* get some relief by compiling the kernel with the option
"optimize as a router, not a server," assuming I've guessed your
problem. There's another option, something like "CPU is too slow to do
useful work," or something like that. Read the description, but my
opinion is that if you really are running out of cycles, get more. Move
the servers off to another machine, or use an old PC as the router.
If the problem is something else, do share it!

Hello,

the process of installing, with dual boot, Linux 5.2. I don't want to be
able to either telnet or ftp to the Linux boxes. I need Linux to act as

He didn't say firewall, he said router. Unless you have a source of ISA
cards with multiple NICs which I've missed, you don't build a router on
any 486.
Actually, it's fairly hard to do with any PC, the multi-NIC cards are
pricy, and I don't know driver status for Linux. You really want to be
able to get at least eight connections to call it a router.
Someone will probably post the source for a 10 port ISA card for $200,
of course ;-)

Hi!
I here's a fix that worked for me: (WARNING: THIS IS FROM MEMORY,
AND MY NEURAL MEMORY IS DEFINITELY NOT NON-VOLATILE :-) )
Add the following line somewhere in the beginning of sys-linux.c
(in the pppd directory of the source code for pppd):
#include <sys/sysmacros.h>
makedev() is a macro that takes two arguments and is defined in
/usr/include/sys/sysmacros.h.

Subject: Help Installing Xircom Realport REM56G-100
Date: Wed, 01 Sep 1999 01:33:58 GMT
Hello All,
I just recieved my Xircom Realport REM56G-100BTX but I am clueless on
how to install in under Redhat Linux 6. I have looked at many how to's
but I get more and more confused. I bought the card because most people
reported good success and easy setup with the card. During te Linux
boot i see a message that the IRQ resource can't be allocated so I am
assuming there is an IRQ conflict going on. Could some one point me in
the direction of a good tutorial (for a Linux beginner) on setting up
this Xircom card with RedHat 6? If someone wouldn't mind posting what
they did to get it going I would be grateful. Thanks!
P.S. I installed KDE as the desktop but cannot figure out where the
good old RedHat control panel is located. Any suggestions?

Subject: IP Masq Changes in Kernel 2.2.12
Date: Tue, 31 Aug 1999 18:30:16 -0700
I just installed kernel 2.2.12. Prior to this, I ran 2.2.1, the
stock kernel of Stampede Linux 0.89. This machine is my internet
gateway and I have set up IP masquerading. I have had to make a change
in my firewall rules to permit ftp access outside my network. With
kernel 2.2.1, I used these rules to permit ftp access from my local
network to external ftp sites:
/sbin/ipchains -A input ! -y -j ACCEPT -p tcp -s 0/0 ftp
/sbin/ipchains -A input ! -y -j ACCEPT -p tcp -s 0/0 ftp-data
Now, I must use this:
/sbin/ipchains -A input ! -y -j ACCEPT -p tcp -s 0/0 ftp
/sbin/ipchains-A input -j ACCEPT -p tcp -s 0/0 ftp-data
If I do not, I am able to ftp into an ftp site, but when I issue the
"ls" command, I get this:
ftp> ls
200 PORT command successful.
425 Can't build data connection: Operation timed out.
Does anyone know why? TIA

There is a cached implementation of NFS desgined exactly for this
purpose, e.g. for serving /usr/local for a roomful of workstations from
a central point. I believe the product "PC-CacheFS" is a version of this
sort of thing.

I just can't figure it out. Has anybody had the same issue ?

If the CGI is properly written, it should output "Content-Type:
text/html" among its headers. The browser is under no obligation to
assume anything it receives is HTML unless told so explicitly.
Likewise, a web server should set the appropriate content type when
serving static pages.
The use of ".htm" instead of ".html" is of course a Microsoft-ism to
support one or more of their broken OS'es with its silly 8-dot-3
filenames.
