Adam,
you have to use NIS+ to do this.
You'll find it in every Linux distribution.
You're running a ypserver on your central host and
ypclients on the other machines.
ypserver holds the account databases (passwd, shadow, group,
hosts, whatever you like to include!).
Every change is done on the central host and then distributed
to the clients by a single command.
This is the normal procedure in UNIX networks.
Regards,
Ralph.

Subject: Email server for Linux
Date: Tue, 12 Jan 1999 22:14:59 GMT
Hi all,
I am interested in any options that Linux has for Email servers, if any. I am
invloved in setting up a small Netware LAN, 15 users, using it for simple file
sharing and printing. There will be a new box for NW 4.11, and all new
workstations running Win 95. They will (probably) want access to email, both
inter office as well as internet. It has been suggested to have a separate NT
server runnung Exchange, but the cost may prohibit this.
Does Linux have any packages similar to Exchange Server in this regard? I
have set up Red Hat in the past, version 4.2 I think, have only seen glimpses
of the latest (5 something) so I am not totally clueless, just mostly :-)The
major concerns are:
- being able to acces from Windows 95 clients
- being able to use their internet domain & email addresses provided with that
domain.
Would be nice to provide dial up connectivity also, but I think we could live
with Win95 handling that.
Any info appreciated,
Tony

I'm working fine on a 100Mbps network with a netcard RTL8139. But I
would like to change the transmission speed cause the 100Mbps hub is wrong.
When I connect Windows machines to the new hub, drivers are
configured like 'auto' and they change the speed automatically. Linux work
like that? Is it working like that? What I have to change?
Thanks a lot

Many times I have used an one 386 for networking purposes (i.e. ipmasq,
printserver using samba) and I have been amazed how little load there
is on the old machine.
Since packets are just going to be routed thru the machine and nothing
cpu intensive will be running on the machine I think you will be
amazed at the results. It's great to be able to use that old stuff
sitting in the closet again.

If you need to place a server on the net and want to scale it up, start
small and see how it goes, see http://announce.com.
We offer Linux or FreeBSD colocation services starting at $50.00 per

Subject: Linux-Windows95 PPP Connection
Date: Wed, 13 Jan 1999 14:37:51 +0800
Hi Folks,
I have an Intel box running Linux Kernel 2.0.30 with PPP 2.0f
suitably integrated with libdes4.04 to allow for client connection to NT
Servers using RAS. I am also using mgetty1.1.5. I can dial out using
uucp, ppp to unix servers or ppp to microsoft RAS. I can dial in
serially or connect via ppp from other unix hosts. What I cannot do is
to dial up from a Win95 PC and connect using Windows dial up networking.
It is my understanding that Win95 dial up networking uses PAP by
default and MS Chap if the remote server demands it. My (modified)
version of Linux PPP will use MS Chap as a client if demanded, but not
as a Server (i.e.. call responder.) This is using the standard
modifications discussed in the readme.mschap80 document that comes with
the ppp source distribution along with integration of the daemon()
routine from sys-svr4.c into main.c in the pppd source tree (I presume
that this routine lives in libutil, but this doesn't appear in the
RedHat Linux distribution.)
Given all this it would appear to me that all I would have to do is
to put a line like:
ppp1 sultan password
into /etc/ppp/pap-secrets where ppp1 is my account name, sultan is the
name of the linux host and password is the password passed by MS dial up
networking. I then make sure that the options.ttyD1 file specifies
proxyarp and all should be well. This is assuming that mgetty does
indeed recognise the PAP request and spawn ppp appropriately. However
this does not work. I cannot see a ppp process on the linux box, the
mgetty log file says 'huh? Junk on the line?' and MS dial up networking
says the authentication process failed. I can probably get this all
working with slip, but I would prefer to avoid this if at all possible.
Does anyone have any suggestions?
Thanks in advance,
John <[EMAIL PROTECTED]>

If you want to play safe, start a telnet session as an ordinary user, then
issue the 'su' command to change to super user (=root) and enter the
password for root.

Subject: Win98 on LAN served by a LINUX
Date: Tue, 12 Jan 1999 16:36:40 -0600
Here is what I have on the LAN:
* LINUX (Redhat 5.2)
* NT
* WIN98
* WIN95
All of them are networked properly (at least they talk to each other)
When LINUX dials out to ISP and connected to the Internet, I would be able
to use netscape or read emails on either NT or WIN95, with IP Forwarding
setup on the LINUX.
Now, I added a WIN98 onto the LAN, and works fine with local machines
through network. But somehow I could not go to any where on the Internet.
Seems that WIN98 is not working with the IP forwarding stuff. I checked the
network setup and to me, it seems to be set up properly (otherwise I would
expect that it did not talk to any local machine at all!)
Any experience or pointers would be greatly appreciated.

Subject: Copying packets over interfaces
Date: 13 Jan 1999 00:05:58 +0200
Hi !
I'd like to set up a linux box with two
network cards connected to two hubs. The first
interface in the box needs to read the packets
in from the first hub, and copy them over to
the second interface and out to the second
hub. Thus traffic on both hubs is identical.
Is this possible ??
For example:
-------------------
H1 -----(a)|172.16.1.1 |
||| | | ---- 172.16.1.6
||| | 172.16.1.2|(b) --- H2 ----
||| ------------------- ---- 172.16.1.9
|||
| --- 172.16.1.20
----- 172.16.1.24
H1 and H2 are the hubs, x.20, x.24 are machines on H1
x.6, x.9 are machines on H2
So packets going between x.1-x.6 are seen by
x.20 and x.24.
My main reason for doing this is that the two hubs
can be of 10baseT and 100baseT respectively and the
box in the middle switches the packets (on a point
to point basis) between the two different hardwares.
Finally I would like to replace one of the hubs by
FDDI, so the box acts again as a fixed router, but
connecting two different technologies. This also
is cheaper than buying a FDDI switch.
I've tried most things up to now, but it doesn't
work. The next step I would think is to write
something like tcpdump, but with a part to resend
the data.
Does anyone know if this has been done before ?
Thanks,
Pete...

Have you had a look at the DNS HOW-TO? It's all I used to initially

postmap is indeed wrong. IBM's offering is called postfix and I think
it is semi-commercial or commercial. The early versions were affected
by the curse of software claimed to be secure---moderate to dire
security problems (postfix's problems probably rated as only
moderate).
None of sendmail's recent problems have been that bad, so you might
use it for its infinite flexibilty and free source code. Cyberpromo's
disconnection beat me to the banning of domains with a certain host as
a name server or MX (any of cyberpromo's servers was my plan).
