The pppd README file that comes with the sources and gets dumped to

Hello,
I've set up an NIS master server and when I run the ypinit -m, I get a
"failed to send 'clear' to local ypserv: RPC timed out" on each map name.
On the client side I get "YPBINDPROC_DOMAIN: Domain not bound" Now, the

Anyone have any answers?

Well try reading some information about SAMBA at www.samba.org that will help
you with your networking questions. Samba will "appear" as an NT server on
your network neighborhood, as for IP addresses.. why not try using the public
class C number such as 192.168.X.X Setting up IP address's on all of your
machines will make your life much easier. you might want to use this scheme
for doing it.
192.168.X.254 = Linux Server
192,168.X.001 = First Windows Machine
192.168.X.002 = Second Windows Machine
ect...
You will have to read about the configuration in setting up your Win98 Machines
to work with Samba. Currently there is two options... one is to enable
encrypted passwords for samba. The other is to change Win98 to send Plain Text
Passwords. Both have there Pro's and Con's. You can find more information
about this on www.samba.org .
Hope this helps you out.

Don't remember for sure.. but this might be an IDENT problem. Couple
of things to check:
1. Do a netstat -na on your Linux box and make sure that your smtp
daemon is listening on port 25. You should also be able to telnet to
port 25 on the Linux box from the Windoze box and get a banner if SMTP
is running. If it's not running find out why... if it is go to #2.
2. Do netstat -na on the Linux box and check to see if the IDENT
server is running on port 113. If it's not (and the default is to
not run it on a few distributions), edit /etc/inetd.conf and remove
the # (comment marker) from the line for ident. Then do a inet
restart and check it again with netstat.
3. If it still doesn't work it may be due to a DNS problem. Outlook
always wants to do a reverse lookup on the server name. If you have
DNS running on the Linux box make sure that it's set up correctly and
that the Windoze box points at it. If you are not running DNS, put a
HOSTS file in c:\windows on the Windoze box (There should be a sample
file called hosts.sam there to help you with the syntax). After all
that, check the setup of the server in Outlook and make sure it's set
to point at the correct ports on the Linux box (it defaults to 25 and
110, but it's possible to change these).
That's about all I can manage to brain-dump at the moment.

I recently purchased a 3Com USB NI (3c19250) for a Dell Inspirion 3200

Plug and play for the Windows 98 driver worked just fine and I can now see

I'd like to find a RH5.2 or Linux device driver for this interface, if one
exists. 3Com claims only W98 is

Is it possible to override the default gateway supplied by DHCP to a Red
Hat linux machine? I have set a secondary gateway in the DHCP service
but the linux machine does not use this gateway. In the Routing section

the desired IP address which has no effect. I know I am probably missing
something very simple...
Any help would be appreciated.

Sorry, change to a distribution like SuSE or RedHat. They have it

Hi,
I am told that a Terminal Adapter (TA) for ISDN is the way to go with
NT due to
the time delays associated with RAS and dial up networking.
But Linux is much better written. Does it make any sense to use a TA
with Linux?
Or is this a quality problem only associated with Windows products?
Is there a such thing as an internal PCI ISDN adapter that is Linux
friendly?
Any suggestions?
