Nonsense -- dynamic allocation _never_ makes sense.  If a machine is only on
the net a few hours a day, then chances are it doesn't *need* an
externally-routable address.  The ISP would be *far* better off giving
everyone a _fixed_ 10.x.x.x address, and reserving the "real" IP addresses
for people that actually need it.  This is easier to set up than DHCP, it's
better than DHCP, and it's the way IP allocation was *meant* to be done. 
Dynamic allocation is a hack that never should have seen the light of day.

I think this brings us up to $0.06 collectively. :)

Hi,

If you want to telnet to another computer by going through wingate, you must 
first telnet to your proxy server: you will see the Wingate prompt. Enter the 
address that you want to telnet to at this prompt.

Wingate> anywhere.youwant.com

Depending on the telnet program you are using, you might have to press a 
combination of ctrl-enter instead of enter.

The FTP in handled in a similar manner.

J'esp�re t'avoir donn� un coup de main. Bonne chance :)

ps: Si tu as d'autres questions sur Wingate, j'ai peut �tre les r�ponses: je 
m'en suis servi pendant un an. � d�faut d'avoir la r�ponse exacte, je pourrai

Hi Wayland,

Not sure I'm following the whole discussion.  From your first post, I think
you said things like http are working and things like ftp are not.  Also, you
are using masquerading.

Be sure you load ip_masq_ftp.o.  Put something like this in your rc.modules:
/sbin/modprobe -a -t /lib/modules/$(uname -r)/ipv4/* and be sure the ipv4
modules were built for your kernel.

If this fixes it, your trouble was reverse masquerading.  FTP builds a link in
the reverse direction to pass downloads.  Since your local address is
masqueraded, the server needs to be told what to do with the incoming
connection.

Hi all.  I have the specs for an ethernet card which I would like
to use.  These include possible io addresses and irqs.  How do I
discover which ones my card is actually using?  Since the module 
can't automatically detect the card, it's asking for these values.

Hi Traveler,

I have little to add to Vasily & Reto, But I would recommend Reto's solution
( and turn off encripted passwords in smb.conf ) as I have had it working
brilliantly using this method. However, one import detail they both missed
out is to ensure you use Samba 2.0.3. I had no end of problems until I used
this version. I also had a few problems with speed of access until I
installed the DNS server especially with Telnet.

Hello,

I just installed Linux a few days ago in my Dell with the 3Com
3c509B-TPO (ISA) card.  Everything
worked well.  Today, I installed a second nic, a 3Com 3c905B-TX (PCI).
I just learned that this is
not a "Tier 1 supported hardware" device according to RedHat.  (Why?)

There is no specific module for the 3c905B in the kerneld configurator,
so I have a few questions.

1) Will the 509 and 905 use the same driver?  I don't think so, but want
to double check.

2) If so, will I have to recompile the kernel?  Why, and what would I
have to do to make sure the
NICs are supported properly?

3) If not, where do I get the driver module for the 905?  Does the
3c59x.c driver at http://cesdis.gsfc.nasa.gov/linux/drivers/vortex.html
support the
905B?  I wasn't sure if that one driver supports all the NICs.

4) Where can I find steps to installing the new driver?

Thanks,
 Chip

Let's say all the ISP's in the world "see the light" and change over to the
scheme you suggest. Then I guess you wouldn't mind handling all those
support calls the ISP's are going to get when one of their users can't run
the latest hot new online game because their is no protocol specific handler
on the firewall. Maybe you're the incredibly fast programmer that's going to
write those handlers in record time and get them to all the ISP's before
anyone notices that their not actually on the Internet and can't run some
protocols because they're behind a firewall. Personally, when I contract
with an ISP I expect them to provide the access to the _Internet_ not some
private network with a half-assed bottle-neck of a router.

Maybe you should _think_ about the ramifications of what you suggest before
you start calling other people idiots. DHCP has solved a major problem with
the Internet. Before it was in widespread use there were predictions that we
would run out of IP addresses before today. For the vast majority of users,
DHCP is the simplest, most cost-effective, and robust way for them to gain
an IP address. For other users (you seem to be one of them) DHCP is
unnacceptable. Those users can find an ISP that will give them a fixed IP
address. It's simply a matter of using the right tool for the job.

To tell you the truth, I would rather have a static IP address for my ADSL
connection, but my telco doesn't provide that option. I guess I could find
an ISP that did, but I have found that with just a little extra effort, I
can connect to my machine while I am away from home with no problem, and a
simple script that posts an HTML page to my ISP's server is all I need to
lead users to my website.

It's silly and childish to berate others for percieved mistakes when you
don't even understand the requirements they were trying to meet. DHCP is
actually an elegant and robust solution to a complex problem. I'd like to
see you do better.

Reply-To: "G.L. Grobe" <[EMAIL PROTECTED]>

I've got win98 over a LAN to Linux(2.2.3) which has a ppp connection to
my ISP. Both can ping each other. Both machines are configured like the
ip-masq mini-howto states, except for ipchains (read below). Linux surfs
the web fine, the win98 box can't even ping outside, or if it is, I
don't see any responses coming back (which I take as a routing prob -
ipchains?). 

I can't find a file called ipchains and I don't quite understand it yet,
but believe this is what forwards packets from my gateway machine to
other machines on the LAN. Should ipchains have been installed with all
the other ip/networking options when installing RH5.2? What package can
I pick them up from/how do I install them? Does this look like it describes the 
propblem?

Any info/other necessary info/suggestions much appreciated?

A few minutes before making this post, I opened several hundred http
connections, several hundred smtp connections, and several hundred finger
connections simultaneously to your machine.  A few minutes before that, I
ping-flooded it from three different locations simultaneously.

I would issue actual page requests to your httpd in order to test that, but I
don't want to grind your disks too bad and don't know if you pay for
bandwidth, so I won't.

If you want to do a real stress test of your networking performance (and
don't have issue with high bandwidth usage), create a test page that's a
reasonably small size and post the URL here.  I'm sure you can get enough
people to set up small scripts that will continously request the file to give
you a good stress-test (I'd put "Please test me" and "Please don't test me"
or some such similar messages in the file, so that people who read this post
late won't be pounding your server for weeks to come :).

You'll probably want 16M of memory.   I was able to install RH5.1 on 8Meg,
but was
unable to upgrade to 5.2 untill I got more memory.

270Meg is enough for a firewall, but if you like to put alot on it 'just in
case' you may
need a little more,  I think used about 450Meg on my install.  But if you're
careful I'm
sure you can make it work, with 270.

486-100 is plenty,  as a firewall, for even a small company.

Subject: diald with dynamic IP / DNS problem
Date: Fri, 02 Apr 1999 09:41:02 GMT

I have configured diald with a dynamic IP address. I have setup DNS locally
because I need it for qmail running on the server to exchange mail via UUCP
(All incoming messages must be routed to a SMTP host on the LAN, that's why I
need DNS, to lookup the SMTP host's name in smtproutes). Now, if some user
opens a TCP connection (e.g. telnet some.host.com) to the internet, diald
starts up properly, does a name lookup and opens the connection. However,
when the name is already in the DNS cache, the connection doesn't work on the
first attempt because the dynamic IP is assigned after diald has started up.
Is there some way to disable DNS cacheing, or any other solution to the
problem?

I have a Linux box running SuSE 5.3 that I am trying to get to recognize
an Ethernet card.  I have two that I've tried, but I got them second hand,
without manuals or anything.  

The first is a Novell card (I searched their site to no avail) with a BD #
738-000228-001 rev. C and Assy # 810-000228-001 rev. C.  The big chip on
the board is a Nat'l Semiconductor that says:

K9242C4
XC03137L
NSC
DP83905AVQB
AT/LANTIC

There are no jumpers or switches on the board so I don't see any way to
configure an address or IRQ.  It's a 16-bit ISA card, with 10bT, 10b2, and
AUI connectors.

The second card I have just has a sticker on the back that says: 

USER FRIENDLY
495123   2-17-95

And the big chip on this one says:

Winbond
W89C905F
340AF23330430

Again, there are no jumpers or switches to configure it.  This one only
has the 10bT and 10b2 connectors.  

I'd like to get both of these up and running eventually, since I want to
set one box up to learn linux and one to connect a network to the DSL line
I'm getting.  I'm new to both networking and linux, so feel free to yell
at me that I should have checked X reference first, as long as you give a
good pointer to X. 8^)  Thanks!
