That's a typo; my machine has ``lo''.
/etc/hosts says:
127.0.0.1 localhost localhost.localdomain
194.222.41.126 vision25.demon.co.uk vision25
I have tried to activate the loopback device using
``ifconfig lo 127.0.0.1'', but unfortunately there is no ``ifconfig''
program on my machine.

1. Yes
2. Kind of silly --- you wouldn't want to virtualize RAM using RAM, unless
you were a real masochist :-) Just make sure you have sufficient physical
RAM for your apps.
3. /proc is a virtual file system as it is --- it doesn't depend on the disk
4. APM
Having agreed that it will work, I have to wonder if you really would rather
use something designed for embedded use rather than linux --- I really like
the idea that I CAN build a linux router, for example, but would much rather
just plug in the cisco and forget it.....

Sounds like the modem is set to a loopback test mode. Here the test

Sounds like that a part of the problem may be at A's end, that when

There should be no problems caused by different pppd versions.

Every machine on a given hub sees every packet sent to and from every other
computer on that hub. If you don't trust the people you're sharing your
network with, buy a switch. Switches forward traffic only to the ports that
need to see it.

Yes... as long as you're staying in the same subnet you're fine. It's okay
to have loose cables.

I bought an 8-port 10Mb hub for about $35. It was from Fortis. Seems to
work fine, and comes with a lifetime guarantee -- though if it ever fails I
doubt I'll bother tracking them down. :-)

where to buy that stuff online. :-)

Hi,
I plan to write a little multiplayer game. Does anyone know of any good
faqs on that subject? I mean, I know how to setup sockets and all that -
but it gets interesting when you come to realtime aspects, how to
implement the server best (to fork or not to fork...), where to
calculate collisions etc. etc.
Any (documented) source code of any other multiplayer games would be a
great help, too!

Not necessarily. Yes it is true assuming the card -only- supports 100Mbs or

On this topic, can anyone recommend a utility which reports whether a card

Hi,
I'm kinda newbie toLinux.
Here's the problem:
I have a small network (about 10 PC all running win95/98).
Only one machine is physically connected to the Internet - this machine
is running win98, and Sygate is the gateway on the network to access
Internet..
>From another computer in the network, running RH Linux 5.2, I can ping
the computer running Sygate (the gateway), but when using Netscape
Communicator it doesn't find this gateway.
It says there is no DNS.
The IP number of the computer running Sygate is entered on the netcfg in
X11.
What's happening?
What have I to configure to access the Internet?
Thanks in advance

Hi
I installed a router with suse Linux 5.3 which enables a LAN with win98
clients connecting the internet using ISDN. Everything is working
properly
except that the Linux box is dialing my ISP every 5 minutes if a win98
box
runs.
All ips are in the /etc/hosts.
Using verbose 3 with isdnctrl showed this:
Apr 19 02:09:51 hades kernel: OPEN 192.168.0.99 -> 137.248.1.8 UDP,
port: 61000 -> 53
192.168.0.99 is the dummy ip adress for my own (dynamic) ip
137.248.1.8 is the DNS server of my ISP.
No kind of inet software runs on the win98 boxes.
Also i found out that netstat -M shows:
udp 1:15.82 192.168.99.100 137.248.1.8 netbios-ns ->
domain(61000)
Has anybody an idea (samba is not running)?

Read more closely before assuming somebody is an idiot [yes, I know I don't
always follow that advice myself, but.. uhh.. screw you, moron]
The original poster was talking about NT (P)OS (Partial Operating System), not
standard Windows NT. I assume that's some sort of hobbled version of the OS,
like Windows CE. I don't know, I've never heard of it before. Then again,
maybe that's just a nickname that the original poster has for NT. Maybe I'm
just smoking crack.

Subject: dhcp and windows 95
Date: Mon, 19 Apr 1999 20:30:57 GMT
I have setup a DHCP server under Linux for our internal network
(192.168.x.x). Anyway, I am able to have win95 pc's use the DHCP server to
assign an ip address. However, I am having problems with the name server
setting. I have assigned my nameserver as
192.168.1.2
And, in fact, I think that the win95 machines are using the ns. However, if I
type "telnet mail" the telnet client tells me the connection was refused. If
I use CRT (a better telnet client for windows), I can choose both "mail" or
"mail.wec" and the port, which is 23. I still get the same error. However, I
can telnet to the ip address, which is 192.168.1.2. Is this a DHCP problem or
a problem with windows? The thing that confuses me is that if I type "ping
mail" or "ping mail.wec", the ping actually works.
(yes, i did "route add -host 255.255.255.255 dev eth0", per the DHCP HOW-TO)
Any insights would be greatly appreciated.
