Hi,
I am searching for a search where I can learn to program in PHP(3). And I
looked at www.php3.net . Are there any suggestions?

It isnt, thats why telnet should be closed altogether, use SSH + sudo
instead.

Not really, there's various utilities out there like ipautofw and slinux to
take the input of a specific tcp port on one machine and direct it to another.
with the slinux utils you would just do:
redir --lport 100 --caddr=10.0.0.2 --cport 80
that would take anything coming in on port 100 and throw it to the NT server's
port 80.. You ofcourse need good old IP Masquerading configured on the linux
machine so traffic coming from your inside web server can make it out.

hi,
I want to backup my hard drive to a dat tape streamer using kdat (kde).
I have SuSE 6.1 and kde 1.1 running. using kdat the backup always has to
be started manually.
my question: is there a possibility to add a line to /etc/crontab that
makes the backup start automatically. kdat is very handy to recover
files. it would be nice to automate the backup process by , if
neccessary, any other programm.
thanx
torsten

I'm sure it does after you get it working. My NFS mounts to my server
just hang. I'm not seeing any error messages on either the server or
client side. The NFS HOWTO has not yet been updated for the 2.1
changes. Does anyone know of a place to find documentation on the new
implementation so I can turn on some tracing?

Unless you have a ISDN T/A on the server side that supports V.90, 33.6
is all you gonna get. The psudo-56k standard requires didgital at one end,
and a lot of other stuff as well.

A real connection? Odd. It shouldn't work at all.

Yes. It should be set to be fed from the server. The server sees the
ether IP address as local to the ether subnet. You need different IP
addresses for every interface, reguardless of type.

Do a ifconfig. I bet it changed the IP address of you PPP interface
durring logon. First, I would set the server to assign an IP address from
a pool of IP addresses unused on the local net. A local ARP table will
show them all attached to the servers NIC. Then I would set the clients to
use DHCP to get the PPP address, or statically set them to the one in the
pool. Give it a shot, and see what happens.

When i made my first experiments with IP Masquerading, i've noticed that some
network services as ftp didn't work properly with it. This appened bcause with
IP Masquerading it is necessary to load some appropriated kernel modules:
I was not successful to make them be loaded automatically (I needed to look
into the kernel to know why... but time isn't so mutch :), so i made a small
function in a bash script that load/unload them when i star up/shut down my
firewall; i hope it will be usefull.
modules ()

FLAGS=""

if [ "$1" = "remove" ]
then

Subject: exim mailer and auth requests, how to disable?
Date: 31 May 1999 09:57:15 GMT
Hello!
How can I prevent exim from sending out an auth request (and waiting about
30 sec for the answer which will never come) when a client is attempting to
make an SMTP connection?
Alternatetively - can I decrease the timeout?
The client is Windows NT and I'd prefer not to install an identd server
there. The exim MTA is version 2.05 and runs on Debian 2.1, Kernel 2.0.36.
There is no firewall between them where I could redirect the auth request.
Thanks a lot for any help!

Allright,
I'll try to be more clear.
I have a client that both can run Windows NT workstation and Linux, and I
have one server that permanently runs Linux.
I want to be able to dial-in from a remote location to the server from my
client (portable) under Windows NT and access the Samba server file shares.
I can without any problem dial-in from my client if I run under Linux.
I have two kinds of problems:
1) Both connecting from my desktop under Linux and under NT, I only get
connected at a speed of 33600. Ideally I would like to be able to dial-in
into the server and have the server to call me back and establish the
connection.All of this I presume has nothing to do with PPP, since this speed
is already established before I get the login prompt. Consider this as a
minor problem.
2) If I dial-in from under NT with a dial-up. I get ppp established, but that
is all there is. I do not see any network traffic between the client and the
server. If I do a PING from the server at that moment to the client, I get
only CRC errors. If I try to telnet from the client to the server, I can only
get a connection during the first two seconds of the established PPP
connection. Could it be some IP conflict? But which one?
These networking settings do work if I connect through the ethernet
interfaces. Do I need to have a different IP setting of the client for my
dial-up connection and for my ethernet connection. I do not intend to use
them simultaneously.
Could it have something to do with the message in /var/log/messages:
'modprobe: can't locate module net-pf-4'? But then again, why does it work
correctly with my client booted under Linux?
Below is a small part of my /var/log/messages file:

The reason you are not getting help is that it is very difficult to
understand what you are asking by reading your post. You are going to
have to provide a lot more information in a much more organized
fashion.
What kind of machines (what OS) are involved in this problem? How are
they connected to each other and to the internet. What are you trying
to do with the machines? What do you know works, and what do you
think doesn't work, and why? Try to put yourself in the place of
someone reading your post. Would you be able to figure out what it is
all about? (right now the answer is no.)
This is not a flame. Please take it as constructive criticism.
