The "obvious" solutions are:
1. Use aliases and throw in each list something aliased to a notify
program.
2. Hack the local delivery agent to do the notification.
Either way you will need some sort of persistent database of who is
connected to what IP and there are lots of possible solutions.

You probably have to recompile the kernel and modules to support your new
card. Depending on your card, you may have to add ("append") the new card's
IO and IRQ address to lilo.conf. Often these can be specified in options
files for modules in some /etc/ subdirectory instead; so if you use modules,
flip a coin or choose whichever you're more comfortable with. I don't use
RedHat 5.1's control panel, so otherwise, I can't say. Good luck!

Looks like you don't have a proper route added to your route table...please post

to ping. Maybe you are in a different subnet?
You should also try monitoring the network traffic with >tcpdump -i eth0(or

Hit me if I'm wrong but aren't you supposed to use 155.33.53.0 if you are
trying to add a 'net'. The way you have it, it looks like you're trying to add
your own IP as a network.
I haven't figured out this subnetting-stuff, but you're in a B-Class network
and your subnet mask looks like a C-Class one...

As you wrote you use the card in PnP-Mode you have to compile it as
module because else the network card is unitilisized while the kernel
does try to find it. Even if you switch it to "Soft-Configuration" you
might have to give the kernel parameters while as module it fits into
the design of YaST.

Subject: ISPS and modems for LINUX
Date: Fri, 12 Feb 1999 15:36:11 GMT
I am new to LINUX and just finished installing the Redhat 5.1 version. My
first success was to get LINUX to boot from a DOS prompt using LOADLIN ( much
faster than a boot floppy ). I was very encouraged by my small victory until
I read in a RedHat hardware compatability list that my modem is one of the
few that won't work out of the box with LINUX. It is a USRobotics 56K
Sportster. Does anyone know where one might find a driver for this modem? If
this is not feasible, would someone recommend a decent external modem? What
are the requirements of a LINUX-friendly ISP? Any recommendations? Thanx.

Subject: TCP port number and process
Date: 12 Feb 1999 17:08:50 +0100
Hello,
[ network dev. in C-UNIX ]
I'm writing an app to monitor TCP/IP connections on my computer.
( Linux RH 5.2 kern 2.0.36 )
Now I have the TCP port number of a connection. How can I get
(very quickly) the name of the program (executable file) using that
connection ?
I think It'll be okay if I get the PID of the process using that
connection.
I found some tables but none which gives the PID with the port number.
Is there someone who can help me ?
bonus : - Is it possible for multiple process to use the same port number
for multiple connections (what about setsockopt SO_REUSEADDR) ?
If so, what else do I need to find the right process ? And how
can I do that ?
Thank you for any help,
Ndrianina

Quite possibly your wu-ftpd is compiled for a different authentication
scheme than what you're using.
I encountered this problem after installing Slackware 3.4, tho I don't
recall it being a problem with my previous Slackware install (kernel
1.3.20). In my case wu-ftpd was probably compiled for shadow or maybe
PAM. I tracked down the wu-ftpd source, scrutinized the Makefile &/or
config files to eliminate "exotic" authentication #define's, compiled,
& installed. This resulted in successful user ftp.

I have @home service, they do not support dhcp in my area. You just set

I get the feeling that dhcp is required by @home in your area. You do not
need dhcp to run both ethernet cards. dhcpcd is the program to be a
client to a dhcp network. dhcpd (notice, one less 'c' in that one) is the
program to be a server..if you require that for your private network. I
have never heard of using both dhcpd and dhcpcd on one machine, but I
don't see why it wouldn't work.

I believe it uses differant libraries. Also, it will kill your current IP
masquerading setup - it uses ipchains instead of ipfwadm. I've heard of
problems with 2.2 and samba. Anyone else want to jump in here?

Subject: replacing the nt box - newbie seeks Howtos and advice
Date: Fri, 12 Feb 1999 08:24:29 -0700
Dump NT run linux! Actualy I haven't had this much fun since my first 128K
PC. Windows has made me lazy! Linux simply makes my brain hurt, or maybe I
need to check my reading glasses.
I have a dsl connection to the Internet that is feeding a NT box runnig
proxy 2.0. My other 3 machines are running 98 and several will continue to
do so. I would like to find a secure way to share the dsl line, supply email
like exchange, local storage for the 98 boxes and of course the same for
Red Hat Linux workstations.
I guess I'm looking for suggestions about proxy vs Masquerade? Should users
pull mail directly or should I run a mail server for local storage? Can I
use an old 386 as a firewall and do i need to? What about all the little
internet toys like MP3, Realaudio and Icq? Samba for file access? I would
love to build a "free" solution to what NT is now doing for me.
By the way Red Hat Linux 5.2 was a cake walk to install on my Toshiba
4015cds laptop.
Thanks

What are those "obvious reasons" that would keep Microsoft from making a
UNIX version of Internet Explorer?
Microsoft has released a version of Internet Explorer for Solaris, and last
time I checked Solaris was just a different flavor of the UNIX OS.

The server has enabled IP forwarding in the kernel but I don't know if I
have to
execute arp or routed or something
I would like the the laptop has an IP of the subnet but if I establish a
new subnet
and I configure the router (executing routed -s or routed -q and adding
the laptop network) the other machines can reach the laptop?
I'm sure that one machine from outside the subnet can not.
