Subject: questions regarding IPCHAINS, IP MASQUERADING & SQUID
Date: 22 Aug 2000 15:35:53 GMT
Hi Everyone,
I am having dilemma and I am wondering if you can help me with
regarding configuring Linux firewall. Let me apologize if the
post is long; however, I would like to be as specific as possible.
My background comes from NT and have been working on it for 4 yr.
I've done work on Checkpoint Firewall and Microsoft Proxy Server
Version 2. My opinion is that everything running on Microsoft
Windows is a piece of shit (pardon my language, but it's true.) I
am not an expert on firewall by any means but windows NT has so
many holes in there that my firewall was essentially useless.
Please don't get me wrong, Checkpoint is a very good product;
however, NT is so buggy that it boils down to not having a firewall
at all.
I understand that checkpoint is shipping out with a new version
that will support Linux platform. However, in the mean time, I am
looking at implementing ipchains and squid on my linux machine.
Here is what understand from my intial research:
Ipchains is simply a packet filtering firewall. It is similar to
Cisco access-list. It works at network of the OSI layer.
Ip masquerading is, in another word, a NAT (Network Address
Translation). This allows your private network (i.e. 10.0.0.0,
172.16.0.0-172.31.0.0, 192.168.0.0) to access the Internet with
a single valid IP address.
Squid is a proxy server that enables http web-caching proxy
server that conserves the bandwith of your network (i.e. let
say that userA goes to www.yahoo.com and sometimes later
userB goes to the same site, squid will provide the userB with
information that it caches previously thus saving the bandwith).
Now here is my problem:
Let say that I have a small network with a network ID of
192.168.1.0/24 (private IP address) that consists of win98,
WinNT and Linux machines with the Linux machine having
two NICs. The first NIC on the linux machine belongs to the
private network with an address of 192.168.1.1. The second
NIC on the linux machine is connected to the Internet with
a valid IP address of 199.0.216.222. This linux machines
serves as a gateway to the Internet. Furthermore, I've
successfully implemented SSH on the linux machine so that
remote users can safely login from the Internet. I really
love SSH.
>From my win98 and winNT machines, I can ping the address
of the linux machine (i.e. 192.168.1.1) with no problem. From
the linux machine, I can get to the Internet with no problem
(i.e. http, ftp, telnet). Here are my questions:
1) I would like to implement IPCHAINS on the linux gateway
machine to prevent unwanted traffic coming into and out of
my private network. How do I go about doing that? What
exactly do I have to do? I've read a lot of books regarding
this topic but they only provide piece-meal answer or they
assume that you are an expert in Linux which I am not.
How do I configure ipchains? Which directory? Please
provide me with specific instructions on how about doing
this? Please do not leave out details even when you think
it is not important. Furthermore, if you have a ipchains
template, I would love to have it.
2) I would like users from win98 and winNT machines to
access the Internet to using services such as TELNET, FTP
and HTTP services. For example, let say I am at a front of
a win98 machine in my private network and I would like
to telnet to George Mason University. So, from the command
prompt, I start telnet mason.gmu.edu.
I understand that I have to implement IP masquerading for
this to work. Again, how do I go about doing this? As I
already mentioned above, lot of books provide piece-meal
solutions but it doesn't help me. Please help me with
specific instructions and please don't leave anything out
even if you think it is not important.
3) Assuming that I have IP masquerading work, do I
really need squid proxy server? I understand that squid
is a web-caching proxy server? Does it mean that in order
to utilize squid, I have to configure all the browsers (i.e.
netscape & Internet Explorer) to use squid? Please help
me on this one. Does it mean that I have to configure
the browsers to connect to the linux machine that runs
squid? Please help
I really appreciate everyone help and efforts. Thanks.
LONG LIVE LINUX. TRASH WINDOWS.
Sincerely,
David

The "best" request doesn't apply only to linux as I've seen messages posted
requesting the "best" television, stereo receiver, home-theater receiver/amp,
speaker, computer, computer parts, etc.... The problem with the posters is
that they don't think before asking as the perception of the "best" is
subjective and could very well be very much out of their price range of
willingness to pay; I know I cannot afford a "best" speaker that cost
around $10,000 so no need to ask which is the "best" speaker to get.

I run a very fast machine (10,000 rpm SCSI hard drives, two 550MHz Pentium
IIIs, etc.), so I do not notice speed differences between KDE and
GNOME/Enlightenment. When I first got Red Hat 5.0 (for my old machine), it
came with a few window managers, and I settled on fvwm. It was the least
worst. It may have been good, but it was too hard to customize, so I left
it as it came out of the box.
When I got Red Hat Linux 6.0 about a year later, it came up with
GNOME/Enlightenment and that was much easier to use. It may have been a
little flakey, but still so much better than Windows 95 that it was a
pillar of stability by comparison. I have been told that at that time
(about 1 year and a half ago, I guess) that KDE was much more stable, but I
did not want to monkey around with it, so I did not try it.
When I got this machine, it came with Red Hat Linux 6.0 pre-installed and
both KDE and GNOME/Enlightenment ready. KDE was the default. I played
around with it for a few days, and it is certainly a competant window
manager, but I switched back to GNOME anyway, because I was more familiar
with it and because I could not take the trouble to figure out how to set
up their networking stuff. Probably would not have been difficult, but I am
frequently patience challenged.

Pressing Ctrl-Z usually suspends the current program running in the
foreground. The command 'fg' will then resume the program in the
foreground while 'bg' will resume it in the background.
C++ has nothing to do with it. It's a job control thing in the shell.
Look for "JOB CONTROL" in the manual for 'bash' (if that's what you're
running as your shell).

Subject: NFS umount problem
Date: 22 Aug 2000 16:59:12 GMT
On my RH6.1 boxes I unmounted my NFS'd CDROM from the import
machine OK, but trying to unmount on the exporting machine I get the
"device busy" error. umount -f doesn't work, same message. I tried also
to use linuxconf to unmount, the linuxconf response says "umount
successful" despite the command line error message "device busy". I'd
like to find a way to determine what could be keeping the CD filesystem
busy, as I can't open the CD drive to remove the CD. I'd like to be able
to solve this without having to kill the NFS process. Is there a way to
track down what's actually keeping the device busy [ps -ax only shows there
are NFS processes active]?

That's because KDE isn't a window manager...
It's a layer sitting on top if kwm (the K Window Manager).

I doubt it's SuSE. SuSE has a very specific license restriction on its
YaST/YaST2/SuSEConfig which forbids charging for copies of CDs that contain
those things.
Mandrake, Definite Linux and many others are based on Red Hat (or started
out that way)
Stormix, Corel and others are based on Debian...
Never heard of easyLinux though.

Not... quite...
You can remount a partition read-only and THEN perform fsck -c -y.

Subject: Cirrus Logic 546X AGP cards and Installation issues
Date: Tue, 22 Aug 2000 17:02:29 GMT
Hi,
I've installed Mandrake Linux 7.0 and even tried 7.1 on my system with
configuration as follows,
ASUS motherboard with K6 AMD 400 MHz.
64 MB RAM
U.S. Robotics 33.6K Fax INT PNP
Cannon BJC 4300 Printer
Cirrus Logic 546X AGP (I could not get precise number if it is 5462/ 5463
etc.)
Microsoft Mouse ( Serial, 2 button)
CDROM ATAPI 6X
Monitor Samsung Syncmaster 17GLi
Problem Statement:
1) I did install first letting the installer to select the options but in
case of Graphics card I selected 5462/5463 and all other Cirrus Logic cards
that start with 546X. Although for a while Xwindows ran okay but then after
a few minutes (say 5 - 8 Minuts whole Xwindows hangs up. I had to reboot
the system.
2) I installed with X 4.0 and got following dump logs attached with the
mail.
3) I can run the Linux on this system from the command line without
running any X windows.
Is there any suggestion that you can offer?
I hope it's not the problem with the Cirrus Logic card driver!
=======================================================================
I've tried installing the same linux 7.0 and 7.1 on a different system with
a configuration as follows,
Configuration: GDS Intel Pentium III 600 MHz CPU With 256KB Cache
ASUS Pentium III Motherboard BX, 6PCI, 1 ISA, 1 AGP
4 DIMM Socket, 512 KB Cache
64 Mb 168 pin PC 100 DIMM SDRAM
10.5 GB IBM 7200 RPM Hard Drive EIDE
1.44 MB Floppy Drive
52X CD-ROM Internal IDE make MRTP
ATI Xpert 128, 16 MB AGP Video Card
Creative LAB SB 128 PCI Sound Card
Monitor Samsung Syncmaster 17 GLi
Mitsumi PS2 Scroll Mouse
Problem Statement: While installation , the installation does not recognize
my CD Drive and asks me first to selct from SCSI or IDE, if I select IDE
then it asks me to select one of the drives such as Sony, etc. But my drive
is not one of them. Even if I select one of the drives the installation
screens asks me for some parameters which I do not know what to enter.
Did anyone encounter these problems before? and if yes then what are the
solutions?

[review snipped]
Gnumeric is a good excel clone, since you're looking for a spreadsheet.
AbiWord is OK as a word processor, though it has quite a few glitches
and missing functions so far. Both programs take up FAR less space then
the applications you reviewed.
I use StarOffice because it contains the only decent presentation tool I
could find. I'm eagerly awaiting the rollout of KDE2, though. I have
Beta3, but haven't had time to test it.
