Subject: A problem with routing
Date: Wed, 03 Mar 1999 13:53:49 GMT
I have a small network at home it consists of 1 NT 4.0 Server, 1 Linux
Slakware box, and an insignificant WFW 311. Now the problem is I have an
ISDN line on the NT box and a modem on the Linux box. The ISDN I use for
work and the modem is to my ISP for personnal stuff. On the Linux box I can
only see the local machines and the internet through my ISP unless I use the
proxy server on the NT box then I can browse the Internet through the ISDN.
But I would like to be able to telnet to a HP 9000 at work but I can't .
I'm not sure where the actual problem lies, I'm assuming it's on the NT box
not able to route the telnet session through the proxy. But I'm not sure.
Any help would be a great help.
Thank you
Jeff

Does anyone have any experience using redhat 5.2 to connect to Media one
express in Chicago?. I am currently running win95 with ishare to connect but
am in the process of getting rid of my nonworking always need to be rebooted
system. I intend to use redhat as a firewall and also on another machine for
all my internet activities and to let my kids keep using 95 until they get a
little older. Any help would be appreciated.

We use sounds.

sniffle for a 486/66
whirr and clunk are printers

It is a security risk, because everybody could set up a fake NIS server.

Linux is like a Vorlon. It is incredibly powerful, gives terse,

Subject: Auomatic E-Mail Generation
Date: Tue, 2 Mar 1999 16:15:13 -0000
Is is possible to setup a condition in the e-mail server in Linux (sendmail
etc) so that when you send an e-mail such as
[EMAIL PROTECTED]
it runs a script/program and returns the generated output from the program
to the
reply address of the client sending the e-mail. The user program, is a dummy
alias, which runs an external script.
Why do I ask this.
Well I am trying to create a routine on my e-mail server whereby a user can
request a file to be downloaded from the Internet by passing in the address
of the file. Hopefully the script will pick up the address of the file and
use ftp to download the file to a local directory. It will then e-mail the
resulting file to the local mailbox of the user in question.
The format of the e-mail would be something like
File: ftp://ftp.test.com/users/test1.zip
Login: homer
Password: simpson
All other details such as reply-to-address would be picked up from the
message header.
This routine would allow the user to disconnect whilst a large file is
downloaded to our local server thus saving dial-up time which the company
pay's for. The user could then dial-in later and download the local file at
full speed of their modem, rather than the slower connection which they will
get by directly downloading it over the net.
Note this is not the only routine I would like to try. I also thought of a
way to pick "lucky dip" lottery numbers. By sending an e-mail to
[EMAIL PROTECTED] then the reply would contain a list of the lottery numbers.
I have still to think of other features.

Well heck, I should of thought of that! :-) We use Samba to support our
Win clients. Thanks for shaking my brain.

Not a problem, we only have to worry about Linux and even then there are
only 4-5 users incl myself.
Thanks again.

You're screwed.
I have one of those miserable Winmodems too. Due to the design there
will be no support for the foreseeable future.
Maybe someone in 3Com/Usr would do the decent thing, yeah right.

Subject: Newbie: DHCPCD problems
Date: Thu, 04 Mar 1999 01:57:30 +0100
Beeing somwhat of a Linux Newbie, i realy need help setting up my ADSL
connection with Linux!
Tried Dejanews, but it didn't help, so i'd really be gratefull for any
help.
I've sucessfully set up the connection on Win98. My ISP uses DHCP to
provide IP-addresses, and all comunication with the internet is done
through a Proxy (Except for a special server used for loging on to the
network, that doesn't use the Proxy).
I use SuSE 6.0, and i downloaded DHCP v1.3, ran "tar", "make" and "make
install", no problems reported.
During startup, Linux reports finding my 3COM 10baseT card, saying:
eth0: 3COM 3COM Boomerang (unknown version) at 0xb400,
00:10:5a:f0:3f:28, IRQ 10
So i've tried to start dhcpcd, withch just returns immediatly, no
errormessages or anything. Running ifconfig reports that
eth0 HAS an inet addr. Does this mean DHCP is actually working? I've
read that it should generat some files into the "/etc/dhcpc" directory,
witch it doesn't. I've createt the directory, but it is empty.
Another guess is that something might be wrong with the nameserver. I
read that i should add something like
nameserver 10.0.0.1
in a file called /etc/resolv.conf
So a created the file and saved it in that directory.
But... No matter what i do, Netscape reports that the Proxy oesn't
exist, and wont even let me save my settings. I've tried skipping the
Proxy-part, but Netscape doesn't find the login server at all.
So... have I missed some REALLY vital part, thus making a fool out of
myself? Is DHCPcd even runing? Is something wrong with the DNS? Is
Netscape just joking?
I use
SuSE 6.0
kernel 2.0.36
DHCPcd 1.3
Gratefull for any help

Add a new DWORD value named EnablePlainTextPassword and give it a value

Have you tried entering the network address you want to use directly? For
instance, try entering "\\foobar\goofy" to access the "goofy" volume on
machine "foobar". In my experience, that'll often get you in, even if
foobar doesn't show up in Network Neighborhood. Occasionally it'll then
cause everything else to appear in Network Neighborhood.
You might also want to look into passwords issues. The default on earlier
versions of Windows was to send cleartext passwords, while the default
with the latest versions of Win95 and Win98 is to encrypt the passwords.
I don't expect this would cause your other machine to not appear at all in
Network Neighborhood, but I'm beyond expecting rational behavior from
Microsoft OSes.
In more direct line with your original question, there ARE other file- and
printer-sharing protocols available. Linux, being a Unix clone, supports
NFS natively. Linux also has AppleTalk support (in the netatalk+asun
package). You'd need software on the Windows side to get either of these
to work, though, and I'm not sure precisely what's available. Try doing a
Deja News or net search on something like "NFS and Windows"; that should
turn up some leads.

Ok, I've setup SyGate, but it hasn't helped me. I still can't ping
either machine from the other. BTW, in past I also tried disabling my
outgoing NIC, but that didn't help.
I must be missing something fundamental about TCP/IP networking. I'm
sure the cards work, the termination is good, and the wiring works. If
I didn't want a Linux network so bad, I think I'd give up!

^^^^^^^^^^^
There's your problem. You need to put the address that people will be
trying to connect to (the one that's visible to the outside world) as
the incoming address. Also, it looks like you've redirected it to
itself - you need to forward it to _another_ machine.
Your ipportfw command should be as follows:
ipportfw -A -t 195.96.x.y:8080 -R 192.168.0.2/80
where 195.96.x.y is your outside visible address; and 192.168.0.2 is
the computer that's hosting the web page.
Beware that you cannot test it from inside your private network. Email
me for a shell account on my machine to test with, since it must be
tested from outside.
