A whole "several months"? Wow! I suggest you check out

Hi there,
I've got a box here with 2 PCI network cards and slackware 4. One of the
cards is easily found by ne2k-pci, however the other one doesn't want to be
co-operative.
I _think_ it's a D-Link 530. However, I've tried both the via-rhine and
tulip drivers to no avail. It looks like it just isn't announcing itself
properly-- here's an excerpt from my PCI bus:
======
Bus 0, device 10, function 0:
Ethernet controller: VIA Technologies Unknown device (rev 6).
Vendor id=1106. Device id=3043.
Medium devsel. IRQ 3. Master Capable. Latency=64. Min Gnt=118. Max
Lat= 152.
I/O at 0xa800 [0xa801].
Non-prefetchable 32 bit memory at 0xe0000000 [0xe0000000].
=====
Anyone come across this problem before? The one card is working, so at
least I have some internet access, but I would like to run IP Masquerading.
Am I going to have to go buy a better card? :)
Thanks!

I recently posted this excerpt from my "input rules" firewall script.
Forwarding is another matter, but similar. I'm posting it because
when this is just what I needed what I was an "ipchains newbie", but I
could never find it. As a network professional you should be able to
get an idea of how ipchains can be used from this brief sample. I
hope it helps!
Also, I'm no network pro like yourself, so my rules may not meet your
needs. If there's anything stupid in there, let me know.
##############################################################
# Note, some of the syntax here may be wrong because I'm did this from
memory.
# It's close. Doesn't that count? :-)
#
# Note: you get a usage counter on each ipchains rule implicitly. It
increments each time
# the rule is met.
#
# safety first! Set the default input policy to "deny"
ipchains -P input DENY
# now you must explicitly accept any packet types or they get denied
# first create user-defined chains for each network interface.
# You can think of a user-defined chain as a kind of subroutine (if
that helps)
ipchains -N eth0-in
ipchains -N eth1-in
# now divert the packets into a chain based upon the device they came
in on
# you don't have to do it this way, but I like to break things up.
You could put them all in the pre-defined input chain.
ipchains -A input -i eth0 -j eth0-in
ipchains -A input -i eth1 -j eth1-in
ipchains -A input -i lo -j ACCEPT
#############################################################
# now let's apply rules for eth0 (lets say it has an IP/netmask of
192.168.99.1/24)
# prevent spoofing of the attached subnet
ipchains -A eth0-in -s ! 192.168.99.0/24 -j DENY
# now apply other rules that accept the packet types that you want to
allow
ipchains -A eth0-in -p tcp -s 0/0 http -j ACCEPT
# i'm not going to enumerate anymore, you get the idea
# Finally add a rule to deny anything that was not excplicitly
accepted. You ask
# if the default policy is already DENY, then why deny it here? Well,
personally, I'm
# bothered if I can't tell where the 37 packets that were denied
# by the default policy came to me from. This let's me find out what
interface the
# packets are comming from by doing 'ipchains -nvL eth0-in'
ipchains -A eth0-in -j DENY
#############################################################
# now let's apply rules for eth1 (lets say it has an IP/netmask of
192.200.99.1/24)
# and so on...
Good luck and don't fear the Penguin!

Does anyone know of work being done to port Linux as a RTOS in an
embedded, I2O environment. That is, is there a Linux that will run on
embedded processors, complete with I2O API wrappers? If so, may I
request appropriate websites and or e-mail addresses for the developers?

I have the same problem. I have a P2-300 laptop running Win 98 and a P2-400
desktop running RedHat 6.0. I re-configured the kernel to include the 3c515
ethernet driver. I get good telnet session response (win to linux login). I
get good response from the http running on linux. I get good throughput from
linux to win for ftp transfers. But, I get poor if any throughput when doing
ftp from windows to linux. I'm running 100base-T, so things should be pretty
zippy.
I'm going to try getting the linux box to login to the cable modem ISP and
test throughput that way. Still looking for the answer!

I just had a similar problem. Everything was working fine and then I moved.
After the move eth0 loaded ok, but was unusable. Turns out that the mother
board decided to change the irq of the network card to the same irq of another
card. After I changed it back, all is well.

I had a similar problem when I upgraded the kernel from 2.0 to 2.2 without
upgrading all the necessary other programs. Once I upgraded all the programs
everything started working correctly.

I believe this would work for you, if I'm reading you correctly... You
could set up DNS caching on the linux box, tell the windows boxes to
use the linux box for DNS and the linux box to use yer ISP.. There's
HOWTOs for DNS caching...
Hope this helps.

I had to rebuid my kernel to support the card I have (3Com 3c515). It works
pretty well. The kernel re-build was not hard, just time consuming. Look in
the "Kernel" HOWTO file. I took the defaults for most of the configuration
questions.

Hello.
I 've got problems in SAMBA.
I can telnet; ftp and http in and out or it is RHtoW98; W98toRH; RHtoRH:
W95to E98; RHtoW95 or W95toRH.
I can "smbclient" from RH5.0 to Windozes.
I can "nethood" from Windozes to RH5.0.
The only thing doesn't work is "smbmount".
Note:I used to use "enter" for password (me set it up like that).
It did work if I "smbmount" RHtoRH at root directory only, since
I could use my root login password, all other directory failed.
This is meaningless since I would like to "smbmount" a windoze
directory or drive.
I configged and configegd and then configged.....but
First "nethood" went blank in Windoze, then I try to restore
smb.conf by configging and configging.... then
Second, now I can't even "smbclient" RH to Windozes.
This means Samba is all out, what a "fight".

| More than likely. It's a simpler design, hence why hubs are cheaper
| than switches. The tradeoff is efficiency.
Efficiency is a somewhat broad term, bandwidth is the issue. In a hub,
if A has a socket to B and C to D, they each see every packet, a so have
only 10Mbit (or 100Mbit) to share for all machines. In a switch the
shared limit is the bandwidth of the backplane of the switch, usually
500MB to 5GB, so both sockets can run at full speed.
This can make a huge difference in latency and throughput for a system
where traffic is distributed.

I am trying to create a centralized cgi machine to service a lab which I work

cgi requests to the cgi machine a problem occurs. The problem is that cgi
data sent by the POST method is not being sent through the redirect. I am

to get around this problem, or any kind of fix? Please email me any insight
you may to fixing this problem. Thanks.

Complete Bullshit. Even now Germany is *still* rebuilding and repairing
from WWII. As for the USA benefitting from WWII, have you even *read*
history concerning the war and just how many US troops died? If I remember
the population numbers of England correctly, it was more than your entire
country (not just your combat dead, but your whole country).

Not in anywhere near the numbers that the US does they don't.

: The rest of the world (tm) dates WWII as 1939 to 1945.
Sources? I personally doubt that. I would be much more inclined to think
that each country dated WWII as lasting for the time of their involvement
in it. Just like the English do. Just like the US does.
