hi everyone,
i am having problems setting up a RH6.0 (2.2.5) masq'ing box that
will allow for a windows box on the inside to play age of empire
over the internet.
i have tried to allow ports to be open/masq'ed using ipchains
but that doesn't do it. i have searched and found numerous
references to 'ipportfw'. A tool supposed to do 'port forwarding'.
i figured if i'd do that then that should work, but i have not
found this magic tool...
is this the right tool or is there anything else i could do to
achieve this (ip_masq_aoe module maybe?). please let me know. i
am desperate and clueless...
thanx for all your help
jp
please post and reply to me!!

The question is how to allow root logins, not how to get around
the problem.
Edit /etc/login.defs and/or /etc/securettys to allow remote login.
Edit /etc/inetd.conf and change the line that invokes in.rshd to
use -h (rhosts) parameter instead of -L (log option).
Make sure the proper entries are in the file /root/.rhosts, there
should be one entry per each line, giving the name of each host
that you want to allow root login.

I have two machines. One is running Windows 98 and the other one has
Windows 98 and linux installed.
I found that both machines can ping each other when they are running
Windows 98.
But when I switch a machine to run Linux, the ping command does not
work.
The linux machine can ping itself through the interface eth0.
Can anyone tell me what is going wrong

Subject: Cannot access anything else except for own static IP address and the loopback
Date: Sun, 1 Aug 1999 18:58:57 +0800
Why can I only send but not receive anything? Whenever I try to ping, zero
packets return! My 3Com NIC card (the 3c905B) using the 3c59x.o module was
set up successfully (Linux recognizes the card during bootup). Also, checked
using the 'ifconfig' command and saw the ethernet card set up with my Static
IP (given by my ISP), my gateway IP and the netmask. Everything looked fine.
Am I missing anything? I even indicated my primary DNS IP and a secondary
DNS IP address. Enabled IP forwarding also (default). Only thing I realised
was when I use the 'route' command, the netmask was 255.255.255.255 (when it
is supposed to be 255.255.255.0). I thought I've set the netmask to
255.255.255.0 (under the routing tab in the 'netcfg'), then why is it
assigned a different value? Does this make a difference? Anyway, I am using
a RJ-45 cable (not the crossover type but the normal direct cable) to
connect to the '10-Base-T' port in my Alcatel 1000 adsl modem. The 10-Base-T
led lights up constantly and I noticed the Tx/Rx led on that modem blinks
all the time (after boot-up). Checking the 'ifconfig', I realise that the
eth0 (the 3c905B) had sent a cumulative no. of packets constantly. (to my
static IP address i think) but without receiving anything.
How to resolve this. I can ping the assigned IP address of the NIC (given by
my ISP) but not to the outside world. Is there a problem with the routing or
something else? Anybody has got a similar problem or anybody who
successfully set up something like mine pls advice me. Been trying to figure
this out for 2 weeks already! Really hope to set it up so I could surf the
net using Linux.
Btw, I have another ATM card (it's a Virata VL 1025 ATM card) in my system
together with that 3c905B card as well except that I did not set the ATM
card (due to no drivers available) in Linux. I doubt this ATM card would
cause anything would it? I dun think there is a conflict since it is not set
up. Using redhat 6.0. The 3c59x.o module I am using for the 3com NIC comes
from Redhat 6.0.
Thanks.

Down to the
Special Dell instructions
A "SIOSIFFLAGS: Try again when starting an ethernet device means
that there is an interrupt conflict. Dell machines tend to
assign multiple PCI devices to the same IRQ line. Generally this
works under Linux -- most PCI drivers are willing to share IRQ
lines (with the inevitable increase in CPU overhead). But some
drivers, specifically several SCSI drivers use the so-called
"fast" interrupt structure that is incompatible with most other
drivers. See IRQ conflict [LINK] page for more information.
Maybee?

When you build Samba, you specify the default file path for the
/etc/smb.conf file. All Samba utilities let you overwrite that default
value and use another configuration file with a command line switch
(generally -s). The same is true for Swat: the default path to its
configuration file is determined at compile time, but it can be
overriden with the -s command line option.

The providing of unqualified answers when there are potential related
security issues is irresponsible, IMhO.
Someone who does not know how to allow root access via telnet (which is
a fairly easy problem to solve) may honestly not be aware that safer
solutions to the problem may exist.
While I've seen variations on how "allow telnet as root" a dozen times
or more in the past few months, I don't understand the requirement, and
strongly question the wisdom of doing what you suggest if the machine
is in any way connected to the outside world.
Since you decided to lecture me above, can you further enlighten me?

Some of us feed local news servers via a dial-up connection
to read off-line or over home LAN later and therefore don't
know of binary content until it has already been
downloaded. If you want to make a binary file available to
readers, what's wrong with simply providing a link to the

Subject: Games and net access via Linux box.
Date: Sun, 1 Aug 1999 20:29:22 +1000
After losing carrier to my ISP due to time out or lost carrier (ie, anything
other than manual log off) I find that for about 10-15 minutes after
reconnecting, I cannot access any games server which uses UDP protocol,
whether on my ISP or another. I don't know if other games protocols are
affected because I've only tried Quake, Quake2, and Half-Life. I can ping
the servers, and Gamespy can even see who's in them, but when I actually try
to connect within the game, it fails until this 10-15 minute time limit is
up (never timed it specifically). The port doesn't matter, nor does the
game. ie, if I was playing Half-Life when I lost carrier, I can't get into a
Quake2 game when I log back on. ICQ works fine.
Something I didn't notice until the other day, is that when I try to connect
with these games, there is absolutely no modem activity at all. The packets
aren't even getting past my Linux box! This never happened when connecting
directly with my Windows machine. If I reset either machine before
reconnecting to my ISP, the problem stays. If I reset both machines before
reconnecting, the problem goes away. So it's something funky going on
between the Windows and Linux machines, I just have no idea what. Someone
please help, it's driving me crazy. It doesn't make any sense at all.
My setup: Windows 98SE, and SuSE 6.1. The rest of it's pretty standard, two
100mbit ethernet cards with IPX and TCP/IP bound to the Windows card. I'm
not an expert on Linux (a friend set it up for me) so don't ask me how I've
set up the ip masquerading or anything. I can answer specific questions
though, like "what is contained in file X?" etc.

I have been using MRTG on Linux for almost a year now. In fact, I have setup
MRTG for a few customers (typically small businesses). It is a very
in-expensive solution that allows them to view not only router congestion,
but also server congestion (on interfaces) using HTML as its display
mechanism. The graphs it creates on a 5min, daily, weekly and yearly basis
can give you the peaks and valleys or your network (at a glance). Of course,
you can purchase HP Openview, Tivoli Netview, Cabletron Spectrum, etc... but
at a significant cost.
Most routers have SNMP running by default. Most distributions of Linux
include snmpd, it's just not enabled by default.
If you were to enable SNMP daemon (snmpd) on Linux and you can monitor its
interfaces. The same thing can be said for NT, load SNMP as a network
service and you can monitor its interfaces. As for MRTG, it uses a form of
snmpget, (type: snmpget on your linux box) which means the device
(system) your are "getting" MIB data from must be running snmpd.

Since MRTG updates its charts (incrementally) based on the polling interval
you setup, you do not loose any data during reboots. Obviously, if you were
to reboot the Linux box that MRTG is running on, you would see a "gap" in
the chart for that time period because it was not able to poll the devices
and update the charts. On the other hand, if a device is rebooted that MRTG
is monitoring, you would also see a "gap" or (0) because the MRTG could not
retrieve MIB data during that polling cycle. One nice side effect of using
MRTG, is its polling cycles are setup through cron. If a device is NOT
responding to snmpgets, MRTG generates an error for that device and prints
it to stdout. Since cron jobs do not have a stdout attached, cron
automatically sends and email to the user you setup to run the cron job.
(like a network admin)

I've been working with the How-To for several days, but it hasn't helped.
It appears that the module is not being loaded at all. The reason for the
funky IP addresses is that our network is "supernetted". We use 192.1.x.x.
I've also used the 3Com cards before with no problem, but not in a
Poweredge server.
