Hi everyone,
I have a DSL line coming into my house and want to be able to host one
machine on the inside that can be accessed from the general Internet
(telnet, etc)(machine 1), but I also want
to be able to attach an additional computer (machine 2) on the inside to
do some surfing on. I only have 1 IP address, and my initial thought is
that with masquerading, I could have both machines behind the linux fw,
but I don't think it would be possible for me to access the machine 1
because from my understanding, masquerading is mostly for sharing
outbound connections.
Does anyone have any suggestions or comments
Thanks in advance.

DNEWS4 News Server Mthly Pointer to FAQ
This message is a brief description of the DNEWS 4 news server
features and a pointer to the FAQ and binary areas.
DNEWS is a high performance NNTP News Server. It is suitable
for large and small ISP's and Corporate Intranets. DNEWS is
available for all common operating systems, installs easily and
is designed to run unattended.
Design :
Database : DNEWS incorporates a database specifically
designed for News, enabling DNEWS to handle full news feeds
more efficiently and faster than other news server software.
This is important as news volumes continue to grow rapidly.
DNEWS can provide significant performance improvements
particularly where resources are limited.
Dynamic Sucking Feed Option: In addition to traditional news
feed options DNEWS also provides the unique Dynamic Feed
option. A Dynamic News Feed offers business and smaller sites
several important advantages over traditional full or
partial news feeds. The Dynamic Feed delivers enormous savings
in Network bandwidth and diskspace compared to taking a full
feed.
Performance is significantly enhanced as the high redundancy
of the full feed is automatically eliminated. Unlike the older
traditional partial feed a Dynamic Feed does not require users
access to be limited or the maintenance of updating selected
groups to meet users changing needs.
By dynamically reflecting users reading habits the server
automatically only gets and maintains those news
groups that users actually want to read. In this way users
retains all the advantages of the full news feed while
enormous saving in network bandwidth and diskspace are
possible.
The process is completely automatic so there is no
ongoing administration .
News Reader Efficiency: The advanced design significantly improves
news server efficiency. On similar Hardware DNEWS will
typically support 2 times as many news readers per server
with the same fast interactive response time.
Scalability: Designed for high scalability DNEWS design will
handle 0-60 Gig news spools most efficiently. Can be
configured with 2-10 Multiple Server processes on single
server each handling 50-200 concurrent users.
DNEWS can be configured to take multiple full news feeds
and up to 16 dynamic suck feeds and can efficiently send
multiple full feeds with built-in Live feed technology.
Easy Installation and Management: Designed to run unattended
DNEWS is easy to install with virtually no ongoing management.
Key Features:
Easy Installation - totally configurable without recompiling.
Low Maintenance - designed to run unattended.
Support for Multiple IHAVE Feeds
Support for Multiple Dynamic Suck Feeds
Built in Live Feeds Technology for sending full news feeds to other
servers with the efficiency of a news router.
News to Web Gateway , for putting news onto web pages , with full
text searching .
New to Mail Gateways (both ways)
PGP authentication (optional)
Flexible Access and Security options for reading and posting.
Flexible Expire Options allowing intelligently response to number of
items and available diskspace.
Advanced 'SPAM' detection and filtering mechanisms.
Email confirmation of posts.
XOVER extensions implemented in software removing the need for a
separate ' XOVER' database
Streaming extensions are built in speeding up feed throughput

You have to configure all the other machines on your network to talk to the
WINS server. They announce themselves via a datagram, once they know that
they should. Ideally, you'll have DHCP on all your machines and can just
change this setting at the DHCP server -- it will then trickle out to your
clients as they renew their leases. If you shorten your lease time to 1 hour
or so, wait until all the leases are on the 1-hour limit, and then make your
changes, it will percolate out a lot faster.
When your remote box announces itself to the WINS server, it will ask, "who
is the master browser?" If that browser has registered with WINS (as it
should have), WINS will tell the remote machine who it needs to contact to get
the browse list.
Personally, I think this is a rather dumb design -- WINS and browsing should
be the *same service*. But it isn't.

Configure every machine on your network to talk to it, and things should
start to work. Remember that when you are using Samba as a WINS server, you
can't have a backup -- so if it goes down, your remote browsing will fail.

Hi
Is it possible to take control over the MAC layer of an ethernet card
in Linux on a PC ?
I want to be able to overrule the carrier sense and collision
detection. Is this possible with any standard ethernet card ?
Perhaps with some minor hw modification.
Any comments are most welcome!!
(I know this might sound strange but I actually _do_ need to do this)

Yepp,, the hardware you need is only "basic" net cards. You dont need to buy
anything special. Today offices are trowing away 10 mbps coax
cards/equipment when they uppgrading to 100mbps. Look around and you can
even get it for free. Or if you want to spend more money buy 2 100mbps cards
and you can run 100mbps in full duplex. The anly thing you need then is two
100mbps cards (around 40 each) and a cross over cat 5 tp cable and you are
fit for fight.

I've done this by putting /dev/null as the login shell for a given user (edit
/etc/passwd). Lets you choose which users get telnet and which don't.

Create /etc/service.switch:
hosts files
aliases files
To prevent sendmail from performing dns lookups.

If you're not 24/7 connected to the net, create /etc/service.switch:

and sendmail won't do dns lookups any more. If this doesn't work, start
sendmail with "sendmail -bD -os -d", and manually telnet to the sendmail port

I'm setting up junkbuster to avoid downloading all the annoying ads. The
installation and set-up went fine. Most sites work fine, but slashdot in
particular never responds to the proxy.
I thought it might be that my blockfile is blocking out slashdot - so I
experimented - if I try to view a banner add directly, junkbuster kicks in
with simple "Internet Junkbuster" page. I don't get any response (except
a timeout after awhile) when I try for slashdot.
Anyone have any ideas?
Thank you!

It will. However, the BIND distribution bundled with the Slackware

a year ago.

Just download the DNS-HOWTO document and do as it says: it gives

Want to be root it telnet window?
1. Log in as a normal user
2. Type: su at the prompt
3. type the root password.
4. You root.
Want to transfer files easily to and from the linux box?
Use Samba. It's not that difficult to setup. I am using Mandrake also and
have attached the samba configuration file. If you already have Samba
installed copy this file to /etc (overwrite the existing one). Edit the
[Global] section of the file (near the top) replace comptech with the name of
your workgroup. Then do the following:
[root@router]# /etc/rc.d/init.d/smb stop
Shutting down SMB services: smbd nmbd
[root@router]# /etc/rc.d/init.d/smb start
Starting SMB services: smbd nmbd
[root@colin colin]#
or simply reboot. This will enable you to view the linux box as a win95
computer in network neighborhood. WARNING!!! The file I have sent enables you
to have full access to the whole hard drive. Be careful.
Colin
P.S
You will need to reboot windows and change the user name
for microsoft networks to root.
You will also need to do this on the win95 system:
1) Launch the Registry Editor as follows:
Click on: /Start/Run
Type "regedit" and press enter.
2) Double click on: HKEY_LOCAL_MACHINE
3) Locate the following Key:
/HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/VxD/VNETSUP
4) From the menu bar select Edit/New/DWORD Value
5) Rename the entry from "New Value #1" to:
EnablePlainTextPassword
6) Press Enter, then double click on the new entry.
A dialog box will pop up and enable you to set a value.
You must set this value to 1.

Anyone ever run ipx over ppp? I know very little about ipx, just
looking for ways for telecommuters at our office to access the file
server. Sounds messy to me, but right now they're using (shudder) RAS
on an unreliable NT box. So, anyone tried it? Would you do it again?

A better solution, unless you have a *REALLY* slow Internet connection, is
to change the MTU on the Linux box to 1500. An MTU of 1500 is an Internet
standard and should be used in all possible situations.
