Subject: Pump, hostname/IP association
Date: Sat, 14 Aug 1999 21:30:50 GMT
I'm currently running rh 6.0 and using pump. Pump is working properly, it
talks to my DHCP server and I am assigned an IP address. I can
send/receive email and use the internet. However, how do I associate my
computer name (hostname) with my IP address. Normally this would be done
through the hosts file but since the IP address is constantly changing,
that is not possible.
This problem manifest itself by programs such as Samba or VmWare not being
able to see my IP address.
Any ideas are appreciated. Thank you!

If you at all familiar with scripting under linux, or batch files under
windoze, then you could create a re-map drives batch or script that gives
all the relevent commands. You could even set it up as a shortcut on the
windoze desktop.
Good Luck!

But, I took linux off my box for a while to play with the BE os. (Very
cool by the way, but not as mature as linux yet)
Anyway, I have a windows 98 machine in my home network and I have the
stupid encrypted password thing messing up my Samba shares.
In the past, I turned off encrypted passwords in the 98 box. I'd rather
enable encyption on the Samba/Linux side. However, I don't remember how
to do the first, and I'm not sure where to start on the second.
Any help would really be appreciated!

I really liked the Gnome/Enlightenment desktop but found it to be less
than stable. Netscape, for example, would frequently just disappear!
I switched back to the KDE desktop and have not had near as many core
dumps or mysterious disappearing apps.
When I have time (Ha!) I'm going to try and figure out what is wrong with
the Gnome setup.

I spent days trying with no success to get diald to work, the latest pppd
with demand dialling took about 30 seconds to set up and works
fantastically. It's only ever dialled up once when I didn't want it to and
that was a dns problem. Try it, you might like it.

Thanks for the reply...
Have you actually tried that? I had already tried that before I
posted the message and could not get it to work.
My modem is a USR Sportster v.90 PnP on COM2. I use ISAPNP to
configure it.
I have created a link for the modem device...
ln -s /dev/ttyS01 /dev/modem
Now I can do page just fine with minicom, so I know everything is
setup properly. (Plus my modem dials up a PPP connection and does
ipmasq for my network, so it's all working OK hardware-wise)
I type:
echo "atdt1234567"\n > /dev/modem
and it just returns to the command prompt. I also tried the cat
command with no luck.

John,
JProxyma ( http://www.intellectronix.com/jpro/ ) is probably
the solution you need. Using its Mapped Link feature
you can create application specific proxies for practically any
network game. You may be better off using a proxy server because
of the improved performance that comes with caching. Our proxy
server has the security features that you are looking for.
In addition to many other cool features JProxyma is one of the first
thrid-party Java applications that support Sun's JINI technology.
Hope this helps.

Subject: Linking DHCP/non-DHCP computers on same network
Date: Sat, 14 Aug 1999 22:59:25 GMT
Here at our apartment we have 3 Win95 computers on a hub connected to
a cable modem. They each get IP addresses dynamically via DHCP. I
would like to add a Linux box to our little network, and I would like
for it to be able to talk with the Win95 machines (via FTP, or
whatever). However, I don't want it to get a dynamic IP address
through the cable modem, I just want it to have a non-Internet static
IP like 192.168.10.1.
I set up the linux computer with that address but wasn't able to ping
the other computers on the hub, or have the other computers ping the
Linux box. Is there any way these computers can communicate with each
other? Has anybody ever tried something like this and had it work? Any
advice would be greatly appreciated.

Subject: Diskless workstation using ethernet boot ROM
Date: Sun, 15 Aug 1999 09:10:00 +1000
Hi
I have an old P75 which I want to set up to work purely as a workstation (an
X-Windows terminal would be great). I am wondering if it would be possible
(and I am assuming that it would) to add a boot ROM chip to the ethernet
adapter (NE2000 compatible) and run this term diskless, using some king of
X-Server program to run the X-Windows session. For that I would probably
use the grunty Alpha I am awaiting delivery on.
Does this sound feasable? Is there anyone out there who has already done
this and could point me in the direction of the correct man pages/HOWTOs?
Could anyone reccomend the specs of the boot ROM that I have to buy?
Thanks alot

Diald is effective but the latest version of pppd supports demand dialing
with just a few lines in the /etc/ppp/options file. Install the latest pppd
package and read the pppd manual it explains it all.

Subject: Connecting Linux to a Mac network
Date: Sat, 14 Aug 1999 16:16:25 -0700
I access the Internet from behind a firewall on a Macintosh-based network.
The server is a Macintosh running Vicom Internet Gateway. Most of the
machines connected to the network are Macs; there are also a few Windows PCs
on the network. We recently switched from an ISDN connection to ADSL. We
also use DHCP for assigning IPs.
My primary computer is a Macintosh. I also have a PC with an AMD K6/200
processor. A few weeks ago, I abolished Windows98 from the PC, replacing it
with RedHat Linux 5.2. I've never had any trouble connecting to our LAN or
the Internet when using Mac OS or Windows. However, when it comes to
connecting with Linux I am absolutely baffled!
Under Mac OS & Windows, all that was necessary was to specify "Ethernet" as
the network type and "Configure using DHCP" for acquiring an IP address and
getting all the other numbers (subnet mask, DNS, gateway, etc.) However,
Linux seems to want me to enter 17 different addresses in 42 different
locations (okay, so I'm exaggerating). Why can I not find a way to get Linux
to simply gather all this info from the DHCP server?
All of the manuals, FAQ's, How-To's, etc that I've been able to locate
instruct me to enter my machine's IP address (I thought the DHCP server is
supposed to assign this...), enter the subnet mask (I thought the DHCP
server is supposed to assign this...), enter the addresses of the
nameservers (I thought the DHCP... well, you get my point.)
I know the hardware works, because it's the same hardware I used with
Windows98. Under Linux, I can successfully ping my loopback address
(127.0.0.1). But I can't ping anything else. So apparently, I'm missing
something important here. I've configured everything as best I can using
netcfg, but my Linux box still can't even find our gateway/server.
Does anyone know of a helpful tutorial that is written for people coming
from a Macintosh/Windows98 background? I'm just a user, not a programmer,
and I'm afraid that I'm too accustomed to being able to tell my Mac "Do
this" and it just does it. I really want to broaden my horizons and learn
something new, and I feel that learning Linux/Unix can also help me get into
a new career. Until I can connect my Linux box to the Internet, I can't get
any new software onto it, and frankly, I'm getting tired of playing
minesweeper and mahjonng ;-)
For what it's worth, I've set up a regular user account for myself because I
know better than to run around as root all the time; I did manage to
successfully install and configure KDE, and I can find the appropriate
networking tools from within KDE. I'm just not understanding what I'm
supposed to _do_ with these tools...

Generally speaking, you're not supposed to use an all "0"s address,
since it's supposed to be the network and you don't use an all "1"s,
which is supposed to be the broadcast address.

This is my solution.
Download TAR98 . Tar98 is a WindowsNT program that allows you to write
and read UNIX Tar format archive tapes.
Tar98 also allows you to write and read UNIX Tar format files.
Then restore the data to an NT system.
Install Microsoft Services for Unix and make the information avialable
for both unix and Windows clients.

It depends what the tape was written with. Assuming it is tar, you
should be able to put the tape in a DAT drive on your Linux system and
read it with tar. There are often strange incompatabilities between
one DAT drive and another, though - these are nothing to do with
Linux. If the SCO system is running on PC hardware you can probably
take out the DAT drive and SCSI card, transfer it to the Linux system,
load the appropriate SCSI card kernel module, and read the tape. You
can't mount the SCO disks on your Linux system.
