Linux Help

Hi,

I'm new to Linux, so i'm paling to install a gateway, with the following,

1. Firewall
2. DNS
3. DHCP
4. SMTP (relay only)
5. Email Virus Scaning
6. Gray Listing (email)
7. NAT
8 Web Cashing
9. Web Based Configuration tool for all above.

can any one tell me the best Linux version to use, (RedHat, Debian, etc)
and the software i can use, like DNS = BIND, some thing simple to use...

the Box will be a P2 with 256MB ram but if i can get it to work on a P1
166Mhz that would be great....

thanks
Kev

Hi Kev

I won't recommend any specific distro, as that's pretty much a religious
decision ;)

But...

QMail or Sendmail should both do the job just fine. If you are only

Should work fine on a P1/166. Depends on how complex your firewall rules
are, and the amout of mail you want to process. Mail Virus Scanning is
rather CPU intensive.

Greylisting (www.greylisting.org) is a new technique to slow the spread of spam, The
technique simply delays the mail 300 seconds and forced the original
mail server to attempt redelivery. Spammers will generally never
attempt redelivery so their mail messages will not get through. Once
the greylisting process is complete future email messages from the
usernames/ip will immediately be delivered to the destination.

It depends upon the amount of network traffic.

Networking daemons (and the IP filtering code) only consume CPU time
when they're actually doing something, and the amount of CPU time used
is roughly proportional to the amount of work they have to do.

Try it. If the load average is consistently high, you need a faster
CPU. If the hard disk is always busy, you need more RAM. If the box is
mostly idle but it still seems too slow, you need a faster Internet
connection.

Well, I don't know about BASIC, nothing really basic when it comes to this
stuff, but prepare to do a lot of reading.

Here is a good site to start you on your way to email security and there
is a very helpful mail list there as well.

http://www.impsec.org/email-tools/procmail-security.html

I've been using this methode along with Spamassassin for years and all my
networks remain virus free since before love bug. :)

> i know i sound really dumb, well i really dont know much about linux

No need to apologize, we all had to start some day. Asking questions is
not stupid (dumb is mute) ignorance is bliss, because you get to learn
what you are ignorant of. :) Enjoy, and keep learning, that's the key.

I think so, firewall, dns, dhcp, smtp, squid should really be there.

RedHat may use scripts to "help" you that just work on Red Hat. tldp.org
and similar offer the "everywhere-working" Documents :)

If you plan to add Web caching to this system (as you mentioned in an
earlier emssage), I think you'll find 64 MB to be too little memory for
good performance. Everything else should be fine.

In Linux, default installs do NOT automatically enable DMA on hard disks.
You'll want to do that in an init script (using the app hdparm, from the
Debian package hdparm).

In my prior reply, I didn't list postfix among the SMTP candidates, but it
is another good one, so should be fine for your purposes (though I myself
have no recent experience using it).

The usual way to maintain a Debian system after setup is by doing online
updates. In fact, unless you have an awful Internet connection, that's
usually the best way to install. That is, get a set of boot floppies (or a
boot CD, depending on your hardware), install the (very small) Debian base
from it, then use apt-get to add the packages you need from an online
repository.

This approach will assure that you get the latest versions of things
(Debian CDs, like pretty much all Linux distro CDs, aren't updated anywhere
nearly as regularly as the online repositories). In particular, it will
makes sure that you get all security upgrades ... VERY important for any
system that is connected directly to the Internet (as a router is).

>now the commands like
>setup on Redhat dont work, how come ? do i need to install any thing
>else ?

If you are asking why a particular command specific to Red Hat doesn't work
on a Debian install, then the answer is probably that Debian doesn't
include the app or the script that implements the command. Not being a Red
Hat user, I don't know what "setup" on a default RH install does.

If you are asking a more general question, you'lll have to be more clear
.... I have no way of knowing what Debian commands you think are "like setup
on Redhat". Also what "now" referred to, and if "dont work" means anything
more subtle than that the command itself is not present.

>leter on i'm going to install a 2nd HDD and Squid and BIND and some AV
>for the email relay, and the RAM to 256MB.

All easy to do using Debian's apt-get and apt-cache package management
system. (Except I don't know what "some AV for the email relay" means ... I
can't parse "AV" in this context.) The extra RAM should handle your Web
caching needs quite nicely. I'm not sure if you'll need the second hard
disk ... it depends on traffic volumes (SMTP and Web caching).

>if any one can give me the basic how to do this, or a link to some sites
>(Linux for Dummies :-)

The Debian installer itself should walk you through the installation
process. The big gotcha to watch out for is NIC modules ... you don't say
what NICs you are using, and stock Debian Linux kernels only support the
most common ones directly. For others, you'll have to install kernel
modules ... the installer prompts you to do this, but it doesn't help you
identify the ones you need.

Last time I checked, the Debian install process still used an old kernel
(2.2.something). Once you have the system configured, and before you set it
up to route and firewall, you'll want to update to a newer kernel ... at
least 2.4.whatever_is_current, maybe even 2.6.something. Unless you want to
compile you own kernel (a good idea for a router, but maybe not such a good
idea for a beginner), you apt-get install a suitable kernel-image-* package.

If memory serves (I'm not certain, though), the stock Debian install kernel
does NOT contain support for NICs that use the rtl8139 driver (or the newer
8139too driver). If that's the "comm one" you are referring to, you will
need to add a module for it to do an online install.

Ah. I guess that's why words communicate better than made-up abbreviations
(for me, AV = audio-visual, but that made no sense in context).

I just skimmed the Debian package list (for Sid; Woody will be less
complete or current) and found that postfix has these associated packages:

amavis-ng - AMaViS "Next Generation"
amavisd-new - Interface between MTA and virus scanner/content filters
amavisd-new-milter - Interface between sendmail-milter and amavisd-new

postgrey - Greylisting implementation for Postfix
webmin-postfix - postfix control module for webmin

Not having used any of this stuff myself, I can neither recommend nor
criticize it ... just let you know it is (probably) there, for you to take
a look at.

I know I'm being timorous for questioning your memory here Ray, but I'm
almost sure when I did my Debian install here (starting from floppies) on
my machine that has an onboard rtl8139 NIC, I did get network support
without loading of additional modules. If I'm wrong - well, what do you
expect from a newbie? :)

About as much as I expect from an old timer with a failing memory. (That's
why I said I wasn't certsin when I posted it ... being lazy, these days I
*always* put a tulip-based NIC in any system I am setting up, then switch
to its "real" NIC after I have the kernel I actually want to use on the
system installed.)

Oh well, command is "modprobe 8139too" or "modprobe 8139cp" or "modrpobe

If you are installing Debian, you might want to look here:

How about Courier for the smtp part?
As Kev said a web based config would be nice and courier comes with
courier webadmin - nice thing to get your setup up and running.
and it some graylisting facilities as well

Hiii guys................


i'm having pro with LAN cards on my Debian BOX, i did the installation 2-3 times but still fail to up the network but i can see form "lspci -v" that the card was detect,

Realtek 8139 both card;s are the same.... maybe a conflict ?

plz help

Glynn,
I'll let you correct me if I'm wrong, but isn't ip filtering also a
memory requirement? I'm thinks specifically of connection tracking.

All of them have memory requirements. Connection tracking is probably
going to be the least significant of those, although, unlike
user-space daemons, it requires physical RAM rather than swap. Even
so, connection tracking needs an extra few bytes per connection,
whereas a daemon which forks for each connection may require a few
hundred Kb or more per connection.

Glynn,
Thats good to know, for some reason I have always been under the
impression that connection tracking could have a significant memory
requirement.

It's potentially significant for a *router* which may be tracking a
substantial number of connections with minimal RAM.

Bear in mind that a basic router (or a router with only stateless
filtering) requires zero bytes per connection: routers deal with
packets rather than connections, and once a packet has been sent, it
(and any memory associated with it) is gone for good.

In that sense, even a few bytes per connection is an increase by a
factor of infinity over zero bytes per connection.

But, unless you're talking about a router which might have to track
tens of thousands of outstanding connections, or one which has very
little RAM, then it probably isn't significant.
