Subject: masquarade multiple private networks
Date: Fri, 10 Sep 1999 02:20:49 GMT
Hi to all.
Could anyone please explain if it is possible to
have multiple private ip networks work with
ip masquarading, and 2) how to do this.
By multiple ip subnets - I mean ones that will let
you forward traffic across them: thus
Real ip 1st private gw 2nd private gw
202.111.222.33 --- 192.168.1.0 --- 192.168.2.0
/ | | |
/ / | \
/ / | \
/ / | \
/ / | \
/ / host 2 \
/ / \
/ / \
/ host 1 host 3
company
subnet
I have tried the following
ipfwadm -F -a m -S 192.168.1.0/25 -D 0.0.0.0/0
then on the second network
ipfwadm -F -a m -S 192.168.2.0/25 -D 0.0.0.0/0
ip_forwarding is enabled ( echo 1 > blah) both private
gateways.
I can ping from both gateways to anywhere on the
internet. I cant ping from either gateway to host1, host2
etc on the second private network.
Arp tables are present and complete in both gateways,
but have no entries in host 1.
machines are pentium class or better, gateway2 is a
single board computer with a pnp lance ethernet card
on the host 1,2,3 side and an aeronet wireless
ethernet connecting it to the first private network.
The pnp lance card works when I configure it as
the first gateway and get rid of the wireless stuff.
It runs linux router project , kernel 2.0.36. Host1 has
a 3com509 card in it.
Any thoughts would be appreciated.

Date: Fri, 10 Sep 1999 03:13:48 GMT
Forgive me for the comp.os.linux.network cross-posting; even though it's
not a development group, I'm hoping someone there may have knowledge of
my problem.
I'm working with a small application that is doing a connect() to remote
host and am having problems with interrupting the connect().
The program was previously written, tested, etc under Solaris.
The connect() is wrapped with an alarm() and a signal handler so that if
the connect() didn't return within the alarm(x) time, the signal handler
would get thrown and interrupt the connect() call. This works as planned
under Solaris, but does NOT work under Linux either under Kernal 2.0.32
or 2.2.0-pre1 (the two enviroments I have available). I also tried
briefly testing sig_action to make sure it wasn't a problem with
signal() itself, with the same results.
The amount of time the connect() itself takes to timeout (10+ minutes)
is WAY too long for this application. I don't really care if I get the
signal application as above to work, I just need something to work, and
prefer if it will work under Solaris, HP/UX, and Linux.
Thanks

Subject: DHCP Problems
Date: Thu, 09 Sep 1999 22:07:48 -0500
Hey all,
I've just installed Redhat Linux 6.0 on a machine with 2 ethernet
cards. I'm using the machine as a NAT box for my private network. The
problem is that the card going out to the Internet, (it's an AOpen PCI
card that is using the NE2K PCI driver), will work if given a static IP
address, but not with bootp or DHCP. I read the HOWTO's and whatnot to
no avail. I noticed that the docs talk about dhcpcd, but my script
calls pump. When the system boots up, I get the message that it is
trying to get a network address, but that it fails. Is it because I'm
using pump? Or is there something else? Any help would be appreciated!
Thanks!
Mike

Subject: Re: HP Pavilion & Network Card problem
Date: Thu, 9 Sep 1999 20:33:32 -0500
Sorry I don't have specific suggestions, but as a word of encouragement I have
set up two servers on different Celeron based Pavilions (a 366 MHz and a 433
MHz) with RH6.0. On both I used the same Linksys 10/100 PCI card which works
with the tulip driver. In both cases I made a few changes in the BIOS but
nothing that should have affected the network. Also, in both cases I yanked that
silly modem/sound card. That modem is almost certainly a winmodem and so will
not likely ever be supported under Linux. I didn't need a modem for the first
box, and I added an external modem to the second (works great). On the first box
I ran RedHat's canned Server installation. On the second box I ran a Custom
install and let it install Everything. The 2nd box also got a small bootable
windoze partition. On both systems I used linuxconf to set up just about
everything and they are both running smoothly.
Although I can't offer a solution, I think you can focus on configuration and
not hardware, as your hardware should be fine. I got the first box up and
running before I removed the modem card. I took it out later for an unrelated
reason. Good luck.

Date: Fri, 10 Sep 1999 03:00:47 GMT
1. Let's say I have junk.com as a registered domain name. Is it
possible/advisable to name my machine "junk.com", or should I always
add a leading name such as www?
2. What are the reasons for requesting delegation of DNS? Is it
advisable if I only have a few machines in junk.com?
3. Let's say my machine is named www.junk.com. If I want to host a
second domain (www.junkstuff.com) on the machine, what should I
request of my DNS service provider? Do I just tell them to add
www.junkstuff.com as an alias to www.junk.com?
4a. If I want people to be able send mail to me at junk.com, what
will my MX record look like?
4b. What would the MX record look like if I wanted all mail bound for
[EMAIL PROTECTED] to be redirected to www.junk.com? How do I request
this?
Thanks for all your help.

That means that the users were quoting too much text. That's a bad habit
no matter where the quoted text is located in the reply.

Actually, the point-by-point method of responding to posts has been alive

Subject: Linux 2.2.10 and Novell SFT-III
Date: Fri, 10 Sep 1999 01:32:00 GMT
Hi there!
I've put several Linux Pc's running a stock 2.2.10 kernel in a network
to replace the same number of hpux wks. Unfortunately, they have to
access a network plotter which seems to dislike linux lpr/rcp/rsh connects,
so I have to go through an existing Novell 4.11-SFT-III server to get plots
out. No problem, just insmod ipx and ipx_interface add eth0 802.3 and
ipx_configure -auto-interface=on -auto-primary=on; first plot gets out in
reasonable time. Then I begin to copy a large set of data from one of the
old hpux'en to one of the new linux'en: 75% packet loss when pinging each
other, strange for a lan.
The I install and activate the same ipx config on the other Linux'en:
within minutes, network connectivity is lost due to millions of collisions.
W* clients disconnect from the network, one othe the SFT-III servers goes
down due to overload in network traffic.
When I ifconfig eth0 down all the Linux'en everything is back to normal.
Seems as if the SFT-III alive packets trigger some kind of broadcast storm
down in the Linux ipx code since normal Novell server don't send these and
I know several Novell/Linux mixed networks which just work fine with single
or multiple servers, but no SFT-III.
Any hints?
see you

Ensure you have no firewall rules running ... and that you have ip forwarding

You need ip forwarding set for eth1 - I assume you did that ?.
Also unless you are using valid ip addresses (or ip masquerading) your
internal
addresses are going to wreak havoc on the net.
I'm guessing you are sending packets onto the net & replies are being sent
to
the real ip owners or the bit-bucket (for the range you indicate) ???
possible :-)
You need to look into ip-masquerading - it is not difficult there are
some good HOWTOS on the
topic.

Got both the nics detected by passing params to modprobe.
I assigned IP addrs to them. I can ping their own IP addr, but if I try to
ping the router it just sits there.
My IPs: 192.168.254.249, 192.168.254.250 netmask 255.255.255.0
Router: 192.168.254.254
ifconfig shows them UP BROADCAST RUNNING MULTICAST.
This should work, it works from my laptop.
Any hints?

Check your modem's user manual.
There is a register you can set to define the escape character.

Hi,
When I installed my Caldera 2.3 I couldn't recall the ether card I had
installed so left out the
net config in the belief I could set it up later.
What is happening is that I select
COAS / Network / Ethernet Interfaces
then select
New Device & from the list select WD8013, SMC Elite 16 (this works
fine - I have Redhat
dual booted on this m/c & RH6 comes up no problems)
As soon as I select that driver I ger error msg
The kernel driver wd has neither been installed as a loadable module on
this system, nor has it been
compiled into the kernel
The wd.o module is sitting in /lib/modules/2.2.10/net/wd.o
it is listed in /lib/modules/2.2.10/modules.dep
Can someone steer me in the right direction re getting this working -
sure don't want to have to
do a re-install just to get the network right :-(

I set up SAMBA and it appears to be working fine. I can mount my shared

the other way 'round. I can see "linux1" (the name of my linux machine) in
network neighborhood, but when I try and access it, it wants a password. To
the best of my knowledge, I did not setup any passwords to access it! Just
in case, I tried all the passwords I have entered onto the linux machine -
none of them work.
how can I disable the password feature in SAMBA. Or if I can't how do I set
