Hi!
I want to allow a WinNT client to use only some spezial IP-adresses.
The rest of the Internet should be not allowed to get access to.
I am just installing my Linux-machine as a proxy-server. (Socks)
Any Howto's, FAQ's?

I am using Redhat 6.0 on a PC, connected to a network via a ne2000
isa-interace.
I have trouble connecting another network via a second interface, and I
can't find a sample conf.modules file to see if my adjustments were correct:
Here's what I added:
alias eth0 ne
alias eth1 ne
options ne io=0x300, 0x340
it seems to me that at boot-time my machine sometimes find eth0 and
sometimes eth1, but not both together.

Hi Folks.
Here is my dilemma:
I have two computers. One is a Win95 box, and the other is a Linux
machine running RedHat 6.0. They are networked and each box happily
communicates with the other. What I want to do now is set up the Linux
box so that:
1. If I (or my girlfriend) fires up Internet Explorer on the Windows
box, the Linux server will dial a connection if the URL isn't local.
2. The Linux box should accept email from the Windows machine and once
or twice a day dial up and forward this mail to my ISP. At the same
time, it should download any mail waiting for us in the pop mailbox and
provide pop access to the Windows client.
3. If an email is marked "urgent", the Linux box should dial up
immediately and send the email.
Can anyone help me? I've heard a lot about diald, but where do I get it?
(man diald says that there is no page for it, so I assume I'm going to
have to download it).
Thanks,
Hugh Saunders

almost certainly no. Look at the description of the card with UTP+coax, does
it support this?
If you go to UTP, you will need a hub. I think coax is dying.

Reply-To: [EMAIL PROTECTED]
For general stuff on smbmount (I do not know what kernel you are using),
look at section 4.14 on my web-page. If that does not help, comment out any
'debug level = ' line in smb.conf and then try running the smbmount with a
debug-level of 3 or above. How to do that will be in the standard
documentation and where *that* is is also in section 4.14.
My ISP seems to filter 90% of all news-items out so I will probably not see
any follow-ups to this.

Can anyone help me with this one.
I have a Tatung TXT5000 X-Terminal, and i must boot it by tftp or nfs.
But it sais that it needs Xnds or nds and probeble some software from
Tatung.
Does anyone have an idea of how to get it booted, or does anyone have
Xnds, nds, or the Tatung X-Terminal software?
Any help would be nice.

Subject: Linux print filter writing
Date: Mon, 21 Jun 1999 02:56:41 -0700
I was wondering if anyone knows where I can go on the web to find
a source for writing my own print filter. I can't seem to get linux to
work with my HP5L laser printer through a Linksys EPSX3 print server. I
have tried everything I can think of including manually editing the
printcap file, but nothing works. So my last recourse is to try and
write my own print filter to get the laser printer to work properly.
The print server works fine in Win98 and the laser printer works fine
when connected locally. But when printing through the LAN the lights
flash and I might get one page and then nothing and it keeps the rest of
the data either in the printserver's memory or in the printer's memory
and the only way to get it out is to manually eject the paper(but it
does not come out correctly and usually does not print the whole page)
or turn off the print server and printer and then turn them back on.
So, if anyone know where I can find information on writing print filters
I would appreciate it.
Thanks,
Roger

The best way is to setup sudo. Then you type sudo appname

Is this refering to a single or multiple processor machine?
Note that WRT to the original Mindcraft test rather specific "fiddles"
were used. Which rely on the the number of NIC's being the same as
the number of processors. Also, IIRC, the required functionality
in NT is new and possibly not even available to any real customer.

Can you physically fit 8 NICs in the machine (and find free IRQ's

If the length of the cable was only limited by the cable losses, one could
extent the mamiximum length by using a low loss cable.
There are, however other limitations to the cable length;
If 2 computers are transmitting at the same time this will lead to a data
collision.
If thay are too far apart, they will not notice the collision because they
will have stopped transmitting before receiving the packet from the other
side of the cable.
A simular situation occurs when the far side of the cable is not properly
terminated: The remote side will reflect the signal and if the packet is
really small and the cable very long, the computer will have finished the
transmission before receiving it's refelection.
This means that the cable length is limited by the speed at wich the
signal travels through the cable (velocity factor; useally 66 % of the
light speed) and the minimum packet length (minimal 72 bytes including
preamble and sfd, 100 ns per bit for 10 Mbps and 10 ns per bit for 100
Mbps ethernet).
The higher the velocity facter and the longer it takes to transmit the
smallest possible packet, the longer a cable may be.
Regards,
Rob

Subject: NT Call Back with Linux ppp connection. Any Help / Ideas?
Date: Mon, 21 Jun 1999 13:30:59 +0100
HI,
I need some help here if possible. At present I connect to the net using
win95, I dial into a server at work which, when i connect to it, prompts me
for my phone number. my 95 box then hangs up and waits for the server to
call it back - therefore enabling me to use the net at my companies expense
(it is all above board!)....
My problem is that i have been using Linux for a while now, and prefer it by
100%, so does anyone know if it is possible to accomplish the same task
above with my Linux connection? I already have ppp set up so i can get
connected via my ISP.
Any help is very much appreciated!

You have to find the program causing the switch into promiscuous mode.
Next step is then either to drop or replace the program or to convince
it with parameters not to switch into this mode.

You do not need to disable it permanently as only root does have the
right to enable this mode.

I would only think about being hacked if it does occour spurious, says
without a good reason. If one is not hacked there is a well-known class
of programs which do use this feature, network-sniffer (tcpdump and
friends) and bridges are contained within.

I have not. If one of my interfaces is in promiscuous mode I know why
this does happen.
