May be true. But, here the main server is internet. And, built round that.

There are many ways to capture data. As you rightly say one is cut and paste.
May it be my preference or, must I follow yours?

Hi all!
I have a linux box with two ethernet cards with adresses 195.114.37.210
and 195.114.37.211, that must act as a router. I connected a win95
macine to 195.114.37.211. The problem is, that when i ping from linux
the win95 box, it dont work. Pinging from linux to , for example
ftp.cdrom.com is ok. If i swap the ip adresses of ethernet cards and
swap the cables - nothing changes, so the both cards are working. Give
me some directions please

try this command
route add "win95 ip" gw 195.114.37.211
if this works you can add it to /etc/sysconfig/static-routes

There is no right or wrong in this one. There is actually no official
standard. It is as you feel comfortable and how people respond to your
question. I for example normally only read the first page of the message (due
to the fact that I get over 1,000 messages a day and do not have the time to
read and scroll all messages) and if I find nothing interesting I skip to the
next message. And being from the western world the first page means top. The
same happens with readers of newspapers. If the first paragraph is not
interesting you skip the rest of the article. No matter what it contains. Now
if the first part contains the quoted portion I assume that somewhere down the
page the question is answered and I skip the rest. But, that is me!!

Im having trouble getting on the network at my school, it works fine
with windows, but I cant get it to work in linux. I know my hostname,
domain name and that I need to use dhcpcd, and when I try it only sends
about 30 packets and doesn't receive any. any idea how to make this
work? I'd appreciate any help. thanks in advance

Date: Wed, 08 Sep 1999 11:33:36 -0700
I've also installed a DHCP server on my desktop at home, so that my
notebook gets routing and DNS info through there. If, however, that is not
an option (eg, you have no server at home, the laptop goes straight to your
DSL ANT) then you might be able to change your /sbin/ifup script so that
when you start pump, you wait for an exit code of 0, and if pump fails, you
configure the network as usual with the information from
/etc/sysconfig/network. Ie, change the part of /sbin/ifup where it says
if [ -n "$PUMP" ]; then
echo -n "Determining IP information for $DEVICE..."
/sbin/pump -i $DEVICE
else
if [ -z "$NETMASK" ]; then
eval `/bin/ipcalc --netmask ${IPADDR}`
fi
etc...
to
if [ -n "$PUMP" ]; then
echo -n "Determining IP information for $DEVICE..."
if /sbin/pump -i $DEVICE; then
echo "done"
else
echo "fail; using defaults"
if [ -z "$NETMASK" ]; then
eval `/bin/ipcalc --netmask ${IPADDR}`
fi
etc...
BTW make sure you have the latest version of pump; the one that comes with
RH 6.0 is buggy.

Does your network administrator also maintain DNS (BIND4 or BIND8)?
If so, then all you need in Linux to resolve Internet addresses
is an entry in /etc/resolv.conf referencing your network DNS server.
domain your.default.domain
nameserver 111.222.333.444 First nameserver
nameserver 222.333.444.555 Second nameserver
This should work until you setup your own caching DNS server
with possible forward entries in youre /etc/named.boot to forward
unresolved DNS to specified servers. Even with DNS server on
Linux, you still need /etc/resolv.conf so that gethostbyname and
similar commands can resolve IP addresses using your local DNS.

I'm having trouble trying to compile the latest version of tulip.c (v. =
0.91). Here's what I've done and the results:
1.. Copied tulip.c (version 0.91) to /usr/src/linux-2.2.5/drivers/net =
(that's where Red Hat's version 0.89 was).
2.. Tried to compile tulip.c from it's directory location using the =
following syntax on a single processor PC:=20
gcc -DMODULE -D_KERNEL_ -Wall -Wstrict-prototypes -O6 -c tulip.c '[ -f =
/usr/include/linux/modversions.h ] && echo -DMODVERSIONS'
(Note that I tried both zero-six and oh-six for "O6"; zero-six generates =
an error message so I assume it's oh-six.)
1.. The following error messages occur:=20
gcc: [ -f /usr/include/linux/modversions.h ] && echo -DMODVERSIONS: No =
such file or directory
tulip.c:100: warning: #warning You must compile this file with the =
correct options!
tulip.c:100: warning: #warning See the last lines of the source file.
tulip.c:102: #error You must compile this driver with "-O".
I checked to make sure that I have the /usr/include/linux/version.h =
file. I'm assuming that the kernel source code is installed (although =
I'm not sure how to verify that) because I installed the Kernel =
Development package when I installed Red Hat.
The error messages suggest a syntax problem (maybe I'm mistyping it?). =
Is it zero-six or oh-six? Are those apostrophes and are they in the =
right place? Do I need to create a modversions.h file?
Thanks.

That would only solve 1/2 of the problem. I *do* want to send the ICMP
port unreachable message, but I want the source IPaddr on that packet to
be the destination IPaddr of the rejected packet. e.g.:
Packet 1: [IP/TCP]
src: a.b.c.d srcport: xxx
dst: e.f.g.h dstport: 23
[data]
Response packet from firewall host: [IP/ICMP]
src: e.f.g.h
dst: a.b.c.d
[data]
See? No packet lists the address of the firewall. This way, no one
knows that system exists, and no one attacks it. STO is a bad thing, but
I don't need to give them a running start either.
I don't see anything in the ipchains docs about re-writing or forging
the ICMP source, but I'm hoping that this is either a hidden feature or
something on the drawing board.
Anyone?

I'm having trouble connecting to my school's
network. I know to use dhcpcd, and it sends
packets fine, but it doesn't receive any
packets. anyone know where I can get some help
for this? I'm really sick of using windows.
Thanks in advance
