It is at http://www.blackcastlesoft.com/uotrace/index.html How to explain
to him that a game tool is reliable is up to you. :-)

Subject: DNS and DHCP working in harmony?
The background
I have a home network that includes 1 printer, 3 NT boxes and 3-5 Linux
boxes. Currently, all hosts have /etc/hosts (or their NT equivalent).
Everybody talks to everybody with no problems - the system works as I
would like it to work.
I just recently setup dhcpd on one of the linux boxes and have set the
rest of the boxes as dhcp clients. leasing of IP addresses works fine.
What I'd like to do
With dhcp, /etc/hosts become irrelevant because they contain hardcoded
IP addresses. What I would like to do is set up a DNS (named) on one of
the linux boxes. I know, this is not a network that needs a DNS - I
just want to do this to learn. Anyway, my understanding of the database
needed for DNS indicates that I need explicit IP addresses to enter into
the database.
Questions
Since I am using dhcp to randomly and dynamically distribute IP
addresses, it is possible to use DNS to do the name-IP address
resolution?
If it is possible, what should I read, review to learn how do to this?
TIA

HI Jeff,
in fact I am running gated and routed on the client box too, so that
might be the problem or part of it. So, to make it clear, do I just have
to remove gated and routed form runlevel 3 for the client machine, or do
I also have somehow to tell the client machine
that it has to rely on the server for routed & gated services?
Thank you -- Stavros

We experienced some problems with the drivers and/or the chip for
100 Mz Ethernet.
I think we had our board vendor back off to the old 10M chip until
the drivers and/or chips were corrected.
I don't know if it has been all fixed yet or not.

Date: Fri, 02 Apr 1999 17:33:42 GMT
1) Verify you have an entry in your /etc/inetd.conf for rsh. It should look
something like:
shell stream tcp nowait root /usr/sbin/tcpd in.rshd
2) Put an entry in your ~/.rhosts file that looks like:
machine username
where 'machine' is the hostname or ip address you gave your Windows 95 box.
You may need to add to /etc/hosts if you use a hostname. username is the
username you log in with in Win 95.
Hope that helps

Subject: Help: info search for Cogent enet card
Date: Wed, 31 Mar 1999 13:24:48 -0500
I've got a mystery card on my hands that I want to stick in an old 486
that will be running RedHat 5.2. I'm trying to find documentation on it
and having no luck searching the web. Hopefully someone here can
help...
Here's what I've got so far:
Mfr: Cogent Data Technologies
Model: Emaster+ AT
P/N: 525001-0002
Copyright 1993
It's an ISA card, and it looks like it has an Intel chipset. Interfaces
are TP and AUI. I found what I thought was Cogent's website, but it was
under construction. Dead end. No luck finding any hardware references,
link pages, etc.
Any help would be welcome!
Thanks,
Eric

the problem is not Samba but win98 (the worstest thing ms did)
there is an .inf file in /tools/mtsutil you have to install on your win98
machine
if i'm not wrong Ptxt_on.inf to turn encrypted passwords off
You have to apply it every time you change networks options.

I've been messing around with a specific problem for some time now. I'm
trying to use my ISDN-adapter (AVM Fritz!Classic) under Linux. I've managed
to get a connection to the internet, but there's something weird going on. I
can ping to the outside world, but when I try to telnet to the same machine
(which does accept telnet) it will hang forever. Anyone have an idea what I
might be doing wrong?
The initialisation I'm using is:
ifconfig ippp0 0.0.0.0 netmask 255.255.255.0 pointopoint 0.0.0.0
ipppd ippp0 file /etc/ppp/my_ioptions.ippp0
-> from this moment on this prompt will hang - the ipppd remains active, but
doesn't run in the background.
isdnctrl dial ippp0
The file /etc/ppp/my_ioptions.ippp0 contains:
debug
#mtu 1500
name loginname
defaultroute
I'm using the isdn4k-utils version 3.0beta2 compiled on, and used on, Linux
2.2.3.
Any feedback is very welcome.

You can use linuxconf in xwin, too - a great utility that comes with the Red Hat
Distribution.
To start linuxconf, go to the start button, then the administration folder, then
linuxconf.
In linuxconf go to the Config | networking | user accounts branch and you'll see the
user accounts maintenance screen.
You can also start linuxconf from a terminal - just go to a terminal and type
linuxconf and the window appears.
See also linuxconf in the Red Hat installation guide.
