replace nospam with phoe in my address or just reply to this newsgroup.
I have a frustrating problem with my 905b NIC's.
First some info:
I have disabled PNP in the BIOS
I have disabled auto-negotiation with 3c90xcfg.exe in DOS
The driver is loaded as module 3c59x 0.99H-WOL
The kernel is 2.0.36
The dist. is RedHat 5.2
My network is 1 RedHat-box and 1 Win98 box (for simplicity).
All NIC's are 3c905b
The problem:
It's the troughput. When transferring files from Linux to Windows (ftp,
smb..whatever) performance is good., about 6mb/s
But when transferring files from Windows to Linux, performance is poor,
about 1-1.2mb/s
At first I thought this was because maybee Linux has poor support for
IDE-drives, (maybee it's fast only one way) so I got a couple of U2W
disks. Imagine my surprise when this didn't help?
I have been searching the newsgroups for cases similar to mine, but has
struck no luck.
Anybody fammiliar with this problem?

pppd invokes a shell script (/etc/ppp/ip-up) when the PPP link has been established,
and
another shell script (/etc/ppp/ip-down) when the link terminates.
Both of these scripts are provided a number of parameters pertaining to the connection
being manipulated. From the man pppd entry for /etc/ppp/ip-up...
/etc/ppp/ip-up
A program or script which is executed when the link
is available for sending and receiving IP packets
(that is, IPCP has come up). It is executed with
the parameters
interface-name tty-device speed local-IP-address
remote-IP-address
and with its standard input, output and error
streams redirected to /dev/null.
This program or script is executed with the same
real and effective user-ID as pppd, that is, at
least the effective user-ID and possibly the real
user-ID will be root. This is so that it can be
used to manipulate routes, run privileged daemons
(e.g. sendmail), etc. Be careful that the con-
tents of the /etc/ppp/ip-up and /etc/ppp/ip-down
scripts do not compromise your system's security.
/etc/ppp/ip-down
A program or script which is executed when the link
is no longer available for sending and receiving IP
packets. This script can be used for undoing the
effects of the /etc/ppp/ip-up script. It is
invoked with the same parameters as the ip-up
script, and the same security considerations apply,
since it is executed with the same effective and
real user-IDs as pppd.
As you can see, parameter #4 ($4 in the script) would be the IP address
assigned to your end of the PPP connection, and parameter # 1 ($1 in the
script) would be the name of your interface (ppp0 or similar).

I have the same problem with battle.net but ICQ works fine. Make sure you are
set to go through a firewall in ICQ. What command are you using for IP
masquerading? Let me know if you find out anything more about getting
battle.net working. So far all I know is that port 6112 has to be open to
send/receive UDP packets.

Hey... Just my $0.02
I think that it actually *CAN* be done.
Uhhh... I seem to recall that Donald Becker
<[EMAIL PROTECTED]> wrote a channel-bonding
patch for use with NASA's Beowulf hack of RH5.
This patch allows for channel-bonded linkage between
cluster nodes, increasing throughput.
I am not POSITIVE that this is what you are looking for,
but then again... It might be worth your time to take a
peek at it.
See <http://beowulf.gsfc.nasa.gov/software/bonding.html>
for a starting point.
Hope this bears fruit for ya....
Cheers!

Reply-To: "razoon" <[EMAIL PROTECTED]>
I have two clients behind a Linux 2.2.4 firewall.
This is my masquerading firewall as it is copied from a reliable source.
# default policy: deny all
ipchains forward -P deny
ipchains output -P accept
ipchains input -P accept
# flush all other commands
ipchains forward -F
ipchains input -F
ipchains output -F
# now setup masq for 192.168 network
ipchains -A forward -j MASQ -s 192.168.0.1/24 -d 0.0.0.0/0
I dont get this:
First i deny every forwarding in both directions
But in the last rule forwarding is accepted on all ports for all
destinations.
So in my opinion every outsider can send his packets to me. Is that right or
not?
That seems contradictory to me.
I cannot imagine this is a safe way to block against unwilling packets.
I would like to see some rules which are safe as forwarding is concerned.
thanks in advance

Okay, I've tried all I can think of to get banner pages to stop printing, to
no avail.
I'm using RedHat 5.2 and the printool to configure various TCP/IP printers
(HP 4MV, Tektronix, etc.); clicking the "supress headers" section doesn't
work; editing printcap and changing or deleteing "sh:" doesn't work. The
extra pages are annoying and a big waste of paper as the average length of a
document tends to be about 2-3 pages.
Advice? Feeling stupd....

Your forward rule will only forward packets from the 192.168.0 subnet (going
anywhere), but it will not forward packets with any other source address
(that's what -s is - the source addresses). You may want to set up a "spoof
guard" rule like in the ipchains docs, so that you can't get input packets
from the outside network that have source addresses that are internal, like:
ipchains -A input -i eth0 -s 192.168.0.1/24 -j DENY
(this assumes eth0 is on the "external" network you don't want to forward)
(should go very early in the rules. Not 100% sure it's -i for interface).
You should probably also add some "input" rules to block connections to your
router/masq box, or else it will get hacked, and then the rest of your network
will be wide open. Since I set up my box with ipchains on the cable modem
(it's on 24 hours a day), I notice 3-4 connection attempts a day from some
strange systems on the internet that are blocked by ipchains. Mostly tries
on "ident", "imap2", and "netbios-*" ports. I basically don't allow anything
connecting to my box but DNS from the ISP, and ftp-data.
Cheers, Andreas
