I found a adsl how-to and it looks like its going to be a snap to
set up.
My only concern was the internet games problems thru the linux machine
and should I forget linux and just plug into the pc.
The reason I say this is a game like tribes does some stuff so you
can play right thru a firewall..TRY that with mech warrior 3 or
delta force.
Mechwarrior 3 has a listing out of what ports you have to open up to
be able to play thru the firewall, only 100.
Delta Force about the same.
What I need to decide is if you open up 100 ports here and 50 prots
there to play a game thru the firewall...what firewall ???
might as well forget a firewall or masquerading and just tie streight
to the pc and play away.
I know there is no problem with ftp, telnet, or surfing the net but
that is not ALL I want to do on my machine.
CAN ??
can I use linux as security and play games on the net ?
thanks again

I need to block out port 67 & 68 UDP on eth0 using ipchains. I also need to
block out the samba ports on the same nic, eth0. Don't know the range of
ports. Thanks for any suggestions.

We would like to use and ip address ending in .250 rather than .1 on
the linux masq server.
.1 is in use by a major server and would not like to change it if possible.
Can we use .250 or do we have to use .1?

true enough. however, mis- or dangerous- usage should be slightly
more awkward than safe usage. this is not so with C/C++.
it often takes more work to look at return values, errno and catch
exceptions than it does to simply ignore them. in C the default
handler is no handler at all. C++ helps somewhat but i still find it
a royal pain in the ass to check and handle

Subject: Problem with news-server
Date: Sun, 02 May 1999 21:26:54 GMT
Hello!
I set up an isdn-dial-in-server about a year ago and about 2 months
ago I added a news-system (c-news) and everything was working fine.
Just about a week ago the trouble began and I ran out of ideas, so I
thought I just might ask the wonderful linux-community. :) (Caution!
slime-tracks!)
The problems:
a) The news system is unavailable at unpredictable times for both, the
internal LAN and for dial-in-users. Just a full reboot helps.
b) Other than before for now about a week it is impossible to retrieve
news for LAN-users while somebody is connected from the outside.
The system:
SUSE Linux 5.1 partially updated with packages from 5.3 and 6.0.
AMD K6-200 with 32M RAM
2 AVM ISDN Fritz!-Cards for dial-in (as I mentioned the dial-in works
fine).
Some clues.
Problem a) might be a hardware-problem, since this is an old house and
trucks going by the main street get the whole house vibrating. The
keyboard or keyboard-socket may have a fault. (I found it not working
once and some playing with the cable fixed that :~)
I don't have any concerning problem b)
If somebody has an idea it would be nice to have the answers by mail.
If I find a solution I'll post it to the newsgroup.
Thanks in advance,
Taar (Olaf Thorbruegge)

Thanks for the tip. I'll use that, then. It does seem odd, though, that
rather than use the default route (ppp0 is the default root -- there is
no default route when not dialed in) it chooses the other one. That
makes no sense to me...

I've tried lpr, the name of the printer, you name it. I do use netatalk. The
only way I can get my other macs to see any printer on my linux box is use lp
for printing in the printtol and use lp in the papd file, but I can then only
use one printer.

Oh yeah, very nice chipset. Works in everything. You need to use the Tulip

Subject: DHCP Linux server and subnets help
Date: Wed, 27 Jan 1999 01:10:21 GMT
I am setting up a DHCP server on Redhat 5.1 running
ISC DHCPD V2-BETA-1-PATCHLEVEL-6
Our network has a router that seperates our class C ip address in to 4
segments.
The subnetting of each segment occurs every so many IP numbers, fo example:
xxx.xxx.xxx.32 is segment A with a mask of 255.255.255.224
The port for that router segment is xxx.xxx.xxx.33 (i.e. the client's gateway
for that subnet).
and so on.
I set-up the linux server on segment A, and configured a couple of clients to
test it. They have no problems getting IP addresses and info from the server.
But when I have a machine, on say segment C of the router, it doesn't work.
my dhcpd.conf looks like so:
default-lease-time 1000;
max-lease-time 3000;
option domain-name-servers 38.9.215.2, 38.9.225.2;
option domain-name "foobar.com";
shared-network FOOBAR {
# Router seg. A
subnet 10.0.1.32 netmask 255.255.255.224 {
option subnet-mask 255.255.255.224;
option broadcast-address 10.0.1.63;
option routers 10.0.1.33;
range 10.234.100.35 206.234.100.57;
}
# Router seq. B
subnet 10.0.1.64 netmask 255.255.255.192 {
option subnet-mask 255.255.255.192;
option broadcast-address 10.0.1.127;
option routers 10.0.1.65;
range 10.0.1.81 10.0.1.94;
range 10.0.1.96 10.0.1.126;
}
# Router seg. C
subnet 10.0.1.128 netmask 255.255.255.192 {
option subnet-mask 255.255.255.192;
option broadcast-address 10.0.1.191;
option routers 10.0.1.128;
range 10.0.1.131 10.0.1.140;
range 10.0.1.142 10.0.1.158;
}
# Router seg. D
subnet 10.0.1.192 netmask 255.255.255.192 {
option subnet-mask 255.255.255.192;
option broadcast-address 10.0.1.255;
option routers 10.0.1.192;
range 10.0.1.209 10.0.1.217;
range 10.0.1.240 10.0.1.248;
}
}
When monitoring the server in debug mode I notice it seems to only be
listening to it's own subnet and none of the others.
Any help would be greatly appreciated.
thanks,
colins stefani

PPP0 wants to use it so it will work. Do a route and you can see
it.
It is your network device and it is our gateway to the internet.
Do
an ifconfig -a after ppp0 comes up.
