For more information on samba try www.samba.org
Couple of things
1 You will need to use encrypted passwords
2 You will need to make sure that the password for the user account on
linux is activated.
Also looke around the news groups for samba I belive that this the best source
of info.

Doesn't NT use NetBUI under the covers when you log in to RAS? Also, you
don't mention whether your Exchange server supports POP3 or IMAP. I
thought it was proprietary myself, though I'm sure there is an SMTP
gateway for it.

It is very real. Where I work I use several Linux and Solaris boxes
and one NT machine for some legacy applications. The NT machine is the
pain in the ass. I use to remotely control all the Unix machines quite
well, from office or home, to the point I completely configured a CVS
and WEB server on a Solaris machine (using the Linux client) without
knowing even where the machine is, including rebooting after applying
OS patches. No way you do it with NT and no way you get the same
control *and* reliability. Windows networking is a joke. Try the DNS
server, works like a charm if the clients are Windows, if they are
anything different you have to patch it manually and it's down more
often than is servicing the net. And yes, I know that by experience :)

when I request a service such as telnet <my provider in /etc/hosts> it

then states
"ppp not replacing existing default route to sl0"
"connect script timed out. Killing script"
Ive tried to add an IP address in route.conf but it dosent seem to make
any difference
apparently its looking for a replacement route for serial line 0. AFAIK
this is a ficticioous device linking to ppp.
I do have slip running when dials starts <slip keep alive>
can someone shed some light to my delimmna?

Subject: eth0 alias defaulting to off...help!!!
Date: Wed, 27 Jan 1999 01:40:38 GMT
any help wpuld be much appreciated here
i installed RH 5.1 on an dell w/ an intel PII MMX (from the CD ROM that
comes w/ the book "mastering linux"; the book was written for a 2.0.32
kernel while the kernel on the CD is 2.0.34-0.6, but X expects a 2.0.34
kernel address. it's fucked up!).
in any case, i installed the 3c59x.o module for my Ethercard manually,
but:
1) the eth0 alias somehow defaults to 'off'
2) when i compiled the modules configuration file and got it to load the
module at startup, sendmail started taking 3 minutes to do whatever it
does at startup (and also the same happens when i start X).
the bottom line is, i can positively NOT get connected to the LAN (ping,
nslookup or anything) although the parameters are right and the module
is loading. i suspect the problem is that alias being 'off' but i have
no clue *where* that is happening or how to change it.
any ideas?
please...

Subject: PPP dial-up connection with RH5.2
I recently installed RH5.2. I used netcfg to configure my ppp connection
as instructed by RH support, I believe everything there to be right. I
click activate and the modem dials out, connects and then hangs up in
about 20-30 seconds.
First, where is the log file so I can look at it.(Debug is enabled)
Second, my ISP says (I don't think they really know for sure) they don't
use PAP and alas I have tried it with PAP and without to the same end.
Please help, it's getting a little frustrating and I'm about to give up.
I tired of trying to decipher the endless trail of FAQ's and HOWTO's and
mini-HOWTO's and man pages.

Get a hold of Samba from http://www.samba.org ... the latest version
will even act as your NT PDC (Primary domain controller) so you don't
have to fork out mega buck for NT Server :-) I'm currently testing
version 2.0 at work in a M$ Domain model that stretches the imagination!
What will it give you besides spare time :-) It will make NT think that
the Linux Server is just like another NT Server as far as connectivity

When a machine connects to your MTA using the SMTP protocol (to transfer mail
to your clients, or your clients sending mail out to the 'net at large), the
first command expected by the MTA is "HELO foo.bar.com". Some MTAs can
be configured to accept mail without being issued a HELO command, but it's
probably best to tweak your sendmail.cf file to prevent this - email abusers
often don't HELO, or forge their HELO (i.e. - "HELO mail.biteme.com", when
reverse DNS shows the machine name to be "dialup.bigisp.net").

Hello People,
I'm hoping that someone can help me out here. I have a Red Hat Linux box on
my network along with a cable modem and an ISDN connection out to the net.
Currently I'm using a quick script I created in Linux, Cable on/off, in
order for me to easily use the cable modem from the Linux box itself. What
I would like to do is have Linux intercept all requests for web access from
itself and clients on my network and redirect them out the cable modem.
Everything else would stay normal and go out ISDN. Red Hat is the router
for my network, I have four network cards in the Linux box, 2 separating my
10/100 side of the network and 2 separating the class C address of the Cable
modem. I'm anticipating that all of my clients would have to sit in the top
half of the 192 segment(The Cable modem) in order for Linux to masquerade,
but I would really like to be able to keep my registered IP's on the clients
themselves. Is this something that proxying would accomplish? Routing
works great, I can ping machines sitting any where on my network, except the
cable modem(I think it'll only allow IP communication from 1 address,
192.168.100.2), that is why I think I have to use masquerading.
To sum it up, can Linux be setup to intercept TCP/UDP requests on specific
ports and redirect them out a different device other then it's default
gateway? But have all other requests go out the default gateway?
I have been to the Linux Documentation project and read most of the HOWTO's
on doing firewalling, proxying, and masquerading. Plus I have read the
HOWTO for IPCHAINS. The HOWTO's on the LDP use IPFWADM which is
incompatible with my kernel, so I'm only able to use IPCHAINS. When I use
the commands specified in the HOWTO's on the LDP they seem to be
incompatible with arguments for IPCHAINS. With enough playing around I'll
be able to figure out how to use IPCHAINS exactly, but I'm really looking
for someone to tell me want I want to do is even possible. That way I won't
go wasting my time trying to do something impossible to begin with. :^)
Thanks in advance!

Did you try this out? I do not see how it does work. In the first run of
the loop [ do {...} while(0);] len does get less 0 in ACKCINAME (I
assume go->neg_name to be 1 as I see no way to get it 0 than a reject
received for this option). With your patch it does skip the ACKCIPROTO
lines and then does run into the loop again because len!=0. On the top
of the loop it then will be trown out of the loop by the check "if ((len
-= CILEN_NETN) < 0)" in ACKCINETWORK. After the loop it does return 0
and the frame is still declared as being invalid. I'am wrong about? If
yes where is my point of failure?
The sense of the other part of your patch I see. Just wondering there
was no warning by gcc about the "if(internal & 0)" never beeing true.
