I use to use MS-Proxy 2.0, which worked well with just about all
applications includeing games. AFter migrateing to linux (useing IP
Masq), the most of the games that I play over the MSProxy like
starcraft cease to work or will not work properly. The reason I
switched is because MSProxy was very slow and required alot of system
resource. So can anyone recommend a proxy software for Linux will
provide the cability that msproxy did.
Thanks

In my route.conf, I have only the gateway here, not the network:

Subject: Terminal stays active
Date: 30 Mar 1999 06:30:55 GMT
We have a problem in here with our small LAN server. We have telnet
accounts from the PCs in the LAN to the Linux server. When they log out,
the connection still seems to exist. So, 'who' also returns users that
have logged out eg an hour before. It can get really bad, up to a 1day
delay between logging out and really not being in the 'who'-list.
This gets annoying because one can get messages from users that are not
logged in anymore. Talks crash too. When one tries to talk with another
user on the network, user names are cludged - even using the tty device
as a parameter to 'talk' does not work.
The system is a Slackware distribution updated with a 2.0.36 kernel.
Does anyone know of this problem?
Thanks,
Pieter

Subject: Switching hubs question?
Date: Mon, 29 Mar 1999 14:03:29 -0800
I don't know much about switching hubs and I was wondering what kind of
performance would I see if I used them? I currently have 2 servers with
70 user workstations running over a 10Mbit network. (Yes, that would be
ten.) I know, I know. Anyway, two of my four hubs can be turned into
switching hubs but would it be worth my wilds to spend the couple grand to
do this? I mean, how much network performance improvement would I see?
Please send me any information/links/comments/or experiencing possible so
that I can make my decision. Thank You.

Subject: DHCP client and server for same machine
Date: Tue, 30 Mar 1999 07:21:38 GMT
I have been using the dhcpm client with athome for some time now with @home
service using the -h option.
I have just gotten a laptop and would like to use a DHCP server so that
I don't have to change the network configuration and reboot in Windows
when I am at home or at work.
I have installed the dhcpd program and set it up for the internal network.
I followed the howto and installed a route as follows
/sbin/route add -host 255.255.255.255 dev eth1
and then started dhcpd
/usr/sbin/dhcpd eth1
The client machines seem to work fine. My problem is that I don't
think that DHCP works on the external machine. I tried
/etc/sysconfig/network-scripts/ifdown eth0 and
/etc/sysconfig/network-scripts/ifup et0
I get DHCP failed message. I assume this is because of the route I added.
Is there any way to get this to work?
Also, does anyone know what port DHCP uses so I can block outgoing packets
from interfering with @home in case I screw up?
TIA
Jeff

Subject: Re: can't get client adress problem
Date: Tue, 30 Mar 1999 07:12:44 -0500
Here is what I understand to be happening:
This usually occurs when your server can't verify the address/name of the
requesting client. When a client makes a connection the tcpwrappers
tries to verify the user isn't spoofing by doing an name lookkup on the IP
presented by the client, then a reverse name lookup to make sure the IP
is correct. You can control what IPs or domains can connect to your
system via the /etc/hosts.allow file.
You get these errors when a connecting host does not have a DNS entry.
A local ISP near here added a bank of 56K modems, but apparently has never
added these ports/hiosts to their DNS. At least that seems to be what the
problem is to
me.

Subject: Accessing same HD by Linux & WinNT
Date: Tue, 30 Mar 1999 12:26:37 GMT
I have Linux installed on a 340 mb HD in an old 486 box. My NT 4.0 box,
which hosts a peer-to-peer network, has an extra 3.8 gb that I would like to
partition equally between NTFS, FAT, and EXT2 partitions.
Primarily, I wish to store Linux executables on the EXT2 partition, as an
extension to the Linux box. I'm not talking about dual booting between OS's
here. The idea is to enable simultaneous access of the same HD by different
OS's.
Am I asking for trouble?

Subject: PPP demand dial/network problem
Date: Tue, 30 Mar 1999 03:43:17 -0500
I'm trying to set up an old 486 to do IP masquerading for several computers.
Currently, I'm using Win95 to test the gateway and having problems with not
being able to ping the Linux computer from Windows.
Using Slackware 3.6.
PPPD 2.3.6 compiled into the kernel.
Network set up on 192.168.0.x.
Configured PPP using pppsetup.
PPP connects to ISP ok.
Starting ppp manually from the prompt works. I am able to use the Windows
computer to surf the net, email,etc. Local network works fine.
Starting ppp with the -d demand dialing option is where the problem starts.
When I do this: Pinging on the local network does not work from Linux or
Windows (timed out). Pinging the internet from Windows does not work (no
response).
Pinging the internet from Linux DOES work. This causes pppd to bring up the
link and connect. After the connection is made, the problems disappear and
the local network / internet works fine. IP masquerading works good also.
After wresting with the whole masquerading stuff for a month, this has got
me stumped. Can anybody give me a starting point to look for solutions?
Config files are below...
Thanks for any help,

I've successfully install Linux Redhat 5.2 but unable to connect to the
internet using it. I can connect to the internet using windows. But when I
try to do so with Linux, it dials the number, then you hear the squarking
noise. Then silence. AT this time I try to "ping" the server to see if it
is working only to hear the computer redialing. So basically, it calls the
number and then it hangs up. To set up, I used the configurator and set up
"ppp". The ISP I use says they use "chap" and not "pap". During setup, I
did not see any tab for "chap" so I assumed it default to "chap", if I did
not check the "pap" tab. Totally new to Linux and totally lost. Been try
to get this to work for weeks....no more hairs left to pull out. Can anyone
help? Pls remember that I am new, really new and really lost.

Hi Steven,
This may sound obvious and I am sure you have thought about it but why not
just use Samba and mount the volume on the Linux box using an NT share ?
If your talking about sharing the HDD across one physical bus then I
wouldn't be sure that it is possible without some proprietary hardware
involved and that would obviously be expensive. I can think of any solution
that wouldn't use SCSI or FC-AL and be provided by some-one like your
DEC/EMC/IBM/BoxHill's of this world.

Just in case you haven't checked Cert lately you should upgrade to Bind 8.1.2
to avoid some security holes in earlier versions of Bind. See
http://www.cert.org/advisories/CA-98.05.bind_problems.html for more
information. I think someone has actually written a worm that exploits this
hole.
