I recently moved NIS from SunOS to Linux.
First move the actual source maps to the linux machine.
Edit the /var/yp/Makefile to point them in the right direction.
(if you have SunOS 4 machines, edit the ypserv startup script to include the
--dns option to ypserv or old Suns using NIS will fail to resolv hostnames)
Shut down the old master
update the /var/yp/ypservers file
start up ypserv on the linux machine
run make. that should do it.
don't forget to edit your /var/yp/securenets file for security sake.

Does the linux ypserv package ignore the /var/yp/securenets file?
I'm unable to lock down ypserv to one subnet on one of my servers.
I've got the file (copied from a Solaris machine where it works) and
I can't for the life of me figure out why it is being ignored. It has
just the single line
255.255.255.0 xxx.yyy.zzz.0
The server is a standard RHLinux 6 machine, with all errata applied.
thanks,

Eric,
1 - in a shell, type...
printtool
2 - click away the notices.
3 - select "add"
4 - enter the login name of the machine that has the printer
5 - enter the password, if any, for that machine, otherwise leave blank
6 - enter the workgroup for that machine's network presence
7 - select the appropriate input filter.
8 - finish the add, click on the new printer entry, and "print test page" from
tests menu
9 - if the text comes out with only one line, click on the printer entry
and edit it, then in the input filter window, click the stair stepping button
(or LF->CR/LF, whatever it's marked)
To actually print, from the shell, this will do it:
ls >tmp
lpr tmp
rm tmp (answer y<CR> to the question)
...that's redirect the output of the dir command to a file, "tmp",
lpr (LinePRint) it, and ReMove the file.
That should do it for you. Note that Linix has pretty sorry printing
capabilities, take a look at Ghostscript for postscript output conversions.
Good luck!

Look at the Proxim Symphony line (http://www.proxim.com/symphony/).
I have the ISA card in my linux gateway and a couple of the PCCard
cards in my laptops. Works pretty good through multiple walls.
They also have a ethernet bridge type thing -- not sure if it can
bridge two ethernets, but it can bridge the ethernet with the wireless
network.
I chose to have the linux box do routing and all seems to work fine.

No, it's the tulip driver. I install these cards all the time, they
work great. It might make a difference to make sure you're cabled to
the LAN before power up. Otherwise, please be more specific as to
the problem, and the driver version.

Hi Rainer,
The office I work at has the following setup that uses a linux-server as an
smtp-server for your windows-clients.
The computer named gateway runs Redhat Linux 4.2 with ip masquerade, apache,
squid and sendmail. Gateway is connected to an ISP on a premanent PPP
dialup 33.6 modem handled by the diald dialer program. Gate has three
registerd domain names on its eth0. One eth0 name is
mail.ourcompany.com.au and accepts internet mail.
Each Windows user has a login account on gateway. Each of the PC's POP3
login to gateway is the user login and password.
In your case, begin by configuring sendmail on Linux to send internet mail
from a login console.
Type mail [EMAIL PROTECTED] and see if it can deliver it.
Do you have a registered internet domain name? If you don't you may
initially have to set your domain name in /etc/sendmail.cf to a resolvable
address, say your ISP's domain name.
When this works each configure each Windows mail program to use the pop3 and
login to the linux box.
If you don't want the linux-server as an smtp-server for your
windows-clients set it up as a gateway to the internet (dialup or permanent)
and use you ISP's smtp-server accounts.
Good luck

Date: Tue, 20 Jul 1999 14:38:58 -0700
Hello,
If you don't want users to telnet to your systems at all, just remark with a
'#' telnet daemon line in /etc/inetd.conf, and you need to restart initd
daemon (if you don't know how, just reboot your machine).
Another scenario would be when you don't want certain users to use telnet,
but want to use it your self, then change their default shell in /etc/passwd
file to /dev/null. They won't be able to open a shell session to your
system.
One more scenario will require more shell programming skills, but it's more
'user friendly' - in user's directory (/home/user) in .bash_profile (login
script file) setup the following script at the end:
echo "You are not allowed to telnet to this system! Sorry..."
sleep 5
exit
It will display "...not allowed..." message and disconnect after 5 seconds.
Good luck!

i bought a new 4 port hub for about $30 on an auction site.
there is a large chain store that sells a 5 port hub
for about $35.
i would tell the name of the chain store
but there are paranoids out here who are suspicious of anyone
dropping of a name such as comp USSR.
paranoids think that anyone who does that is doing a commericial although
it is true that i get about $100 comission for each person from this
newsgroup visiting my sponsor. also just to be completely ethical i
should say that i have a very sophisticated way to figure out the
effectiveness of my commercial. basically it involves a spy satellite

Subject: Kernel 2.2.10, Mandrake 6.0 and NFS
Hello,
I have installed Linux Mandrake 6.0, and I had to compile a new kernel
for a support of my D-link ethernet card.
When I restart the computer (after a normal kernel compilation),
everything is fine but one thing : the nfs daemon.
in the init scripts, the message is :
starting nfs daemon : nfssvc : Function not implemented.
When I start Linux with kernel 2.2.9 (installed with Mandrake 6.0), the
nfs daemon (knfsd, called by the appeal 'rpc.nfsd') works fine (but my
ethernet card does not !).
Can you please help me ?
Jerome.

DHCP servers are broadcast based, which means you don't need to specify
which one you want to get your IP from.
You can probably do it in Linux, but most of cable company's users are
Windows based and Windows does not have that option, so it could be that
they are asking for something that is not normal setup.
Good luck!

I've put up with this problem for a while but now I have go-live on the mac,
with a crap non-configurable time-out I need it sorted.
Logging in from another machine usually takes well over a minute. With Top I
can see in.ftd come in straight away and then just sit there, I even tried
nicing the blighter with a -20 to no effect.
The machine doesn't usually run in ideal conditions with X, Apache and more
runing on a 32MB MMX. However, with just the basics, I'm left with over 10MB
of real memory left and still the same problem!!!
The machine is allocated a name and domain but they are rarely used. I have no
experience with DNS and haven't had the time to look into it but I soon will.
Whenever the machine is referenced it is by the IP address. I notice 'funny'
things though, ie netscape running on the server, pointing to a relative local
http URL, picks up the DNS name (non - internet registered - betsy.ad - on
255.255.255.0 subnet).
My only hunch but unlikely yo be the problem.
Your help is much appreciated,
thanks for reading,
