sudo might be the answer. It allows you to give permissions on a

Subject: Firewall Redhat 7.1 setup?
Date: Wed, 09 May 2001 14:48:48 GMT
Hello,
I am trying to install a firewall under Linux RedHat 7.1, kernel 2.4.
2 days that I am trying to understand what to do... }:o(
This is my configuration.
- One server under RH7.1 with an ethernet card (eth0) for the internal
subnet (protected) an other ethernet card (eth1) for external subnet,
which can connect to the Internet by a gateway.
The object is to allow connected PC on the internal subnet to access
the internet and other services (like w2k authentification).
But for the moment, I would like to ping a computer on the external
subnet from a computer on the internal subnet. And nothing happens...
:o(
This is what I found on the web:
- Ipchains is used by default by RH7.1 instead of iptables.
If I want to use iptables, I need to make a new kernel. True?
- Under RH7.0 we could use /proc/sys/net/ipv4/ip_forward to make ip
forwarding. Under 7.1 this is not usable (I get an error message).
What should I use instead? How to configure?
- There must be a route for eth0 to connect on the gateway on the
external subnet. True?
Who could help me?
I would like to find a howto setup a firewall on RH 7.1 kernel 2.4
The basis, please.....
Thanks in advance for light.

Hi all,
I wanted to install Suse Linux 7 and Windows 2000 on the same PC.
I intalled Linux first in the sectors 1 -> 882 (Swap 882 -> 892) and
then created 3 partions in the extended partition. The first one (hda5:
893 -> 1912) should be used for windows 2000 as c:\
I booted my PC using win98 startup disk and run the installation from
the win2000 CD.
After the first part of the installation was achieved the program
rebooted the PC to complete the installtion.
But I got always the LILO bootmanager and could not access windows.
I booted Linux and added to LILO a "win" boot image that should boot
from hda5 but in vain.
Any help is appreciated

Sending this message to comp.os.linux.networking could result in better
answers...
But I just had the same problem with Redhat 7.1 too...
I used ipchains to solve it and it's very cool to use now...
You can try /sbin/ipchains -L
to list the current rules
You can add a MASQ rule for your LAN that will let them connect to the internet:
/sbin/ipchains -I forward -s 192.168.0.1/255.255.255.0 -d 0/0 -j MASQ
-I stands for insert in forward
connection comes from -s IP/MASK and goes to -d IP/MASK (0/0 means
everywhere...)
and -j MASK indicates the packet should be masqued...
You can make the forward policy to ACCEPT with
/sbin/ipchains -P forward ACCEPT
And save the current rules with:
/sbin/ipchains-save > /etc/sysconfig/ipchains
But 'man ipchains' will give you better help on different commands...
Hope this helps!

I keep Win98 and Mandrake 7.0 on seperate disks and everything is

I need to repartition my windows disk, and therefore reinstall
windows. However, I know this will wipe out LILO.
Everything works fine at the moment, and afterwards I'm thinking it

copying the LILO config to where it needs to be.
Can anyone clarify/confirm before I screw the mbr by reinstalling

I have Mandrake 8.0 on a Pentium 200 with 64MB RAM. The system is on a
network and I access it from another Linux box. The Mandrake system stops
responding (including ping) after sometime. This stopping seems to
correspond with the times when the console terminal goes on screen-save
mode. When I hit a key on the main console that brings the console back
alive, the ping from the other Linux box starts working!
Is this really possible? Or is there any other problem I should be looking
for? Is there a fix for this?
Completely clueless,

How exactly do you need to repartition it? Parted is pretty
clever these days and perfectly capable of shrinking
Windows98 partitions.

Kind of the wrong forums but I don't think it does. Some
flavours of NT can be fussy about which partition it gets to
install on. Whilst you have a Linux boot disk and don't muck
with the Linux partitions its pretty easy to recover things.

Subject: Question: One IP Address w/ Two Servers
Date: Wed, 09 May 2001 15:43:20 GMT
I am getting a single static IP address (I have a dynamic IP address now).
Having the static IP address will work for a single Linux box ~or~ a single
Windows NT Server box. What I am wondering is if there is some way to have
both servers use the single static IP address. The static IP address will go
to a Cisco router and then to my local network.
For example, what I want to do is have the Linux box handle the domains
abc.com and def.com: www.abc.com, smtp.abc.com, www.def.com, smtp.def.com,
etc., and have the WinNT box handle the domain xyz.com: www.xyz.com,
smtp.xyz.com, etc. What I would ~really~ like would be to have www.abc.com
on the Linux box and www1.abc.com on the WinNT box.
I know how to create sub-domains and set up services on both systems, but
I'm not sure how to use both servers simultaneously. Any hints, suggestions,
directions, or pointers to information would be greatly appreciated.
This is a learn-as-I-go project and I get stuck occasionally. :^(

If you have to reinstall windows, it will overwrite the MBR. Create a linux
boot disk that allows you to boot the installed linux system. From there you
just call lilo again to restore your dual boot configuration.

You don't even need to copy it. The LILO configuration file is in
the Linux filing system and the Win98 installation shouldn't touch it
(unless it screws up badly and splats the Linux partition). Simply
boot with your boot floppy and at the shell prompt type "lilo". This
will cause LILO to be re-installed with the same configuration and
you should be fine.

Couldn't find the XFS site?
http://linux-xfs.sgi.com/projects/xfs/
I installed RH 7.1 using SGI's XFS installer on monday, except for a couple
of harmless messages on boot because of SGI's kernel using devfs everything
looks good so far. You can disable the use of devfs on boot using
"devfs=nomount". From the XFS site:
Maximum File Size
For Linux 2.4, the maximum accessible file offset is 16TB on 4K page size
and 64TB on 16K page size. As Linux moves to 64 bit on block devices layer,
file size limit will increase to 9 million terabytes (or the system drive
limits).
Maximum Filesystem Size
For Linux 2.4, 2 TB. As Linux moves to 64 bit on block devices layer,
filesystem limits will increase.
Filesystem Block Size
Currently fixed at the system page size - 4K on IA32. Filesystem extents
(contiguous data) are configurable at file creation time using fcntl and
are multiples of the filesystem block size. Single extents can be up to 4
GB in size.

ReiserFS still has data corruption problems. I can't say how stable XFS is
I just started using it, but is has supposely be exstensively tested.
However I would not trust it on a system with critical data yet.

Try looking at the log screens (press ALT + Function Keys). It sounds like your

Use the program 'minicom' (should be included in your distro - otherwise
look
at the SuSE site or do a search on the internet. It's pretty standard.)
With that you can modify the serial port settings as well as send

Hmm, I wouldn't bet on it, that windump installs on any partition except
the first primary partition at all. I have never tried it and I heard
something about windows
always using the letter c: for the first primary partition of the first
harddrive.
Did this change in Win2k????
I think you would be better off by letting windump have it's will and
let it use the primary partition and use the others for linux.

Since you are going to have a Cisco router handle incoming
connections, the router will have to decide which server
to send the packets to. As such, c.o.l.setup is not really
the appropiate place for help, Cisco is. For us to help
you, you might have to make some changes. The linux box
can be setup to handle incoming packets and forward those
for the NT box to the NT box. I think this is part of
IP_MASQ which you can read up upon. You might also have
to look into ipchains/iptables for the rules to do the
forwarding.
