Hi!
Ich meochte/muss auf der Linux Kiste mit einer Netzkarte eth0 zwei Netzwerk
Klassen laufen lassen. Als default habe ich ein Class C-Net mit 192.168.1.1
mit einer Subnetmask 255.255.255.0 als Adresse fuer den Linux Server. Nun
sollen aber auch alle Betreiber des Class A-Net mit 10.0.0.* mit einer
Subnetmask 255.255.0.0 auf die Linux Kiste zugreifen koennen. Ist das
moeglich? Leider laesst sich keines der beiden Netze ohne Probleme umstellen.
Das ganze System laeuft mit einer SUSE 5.1
Kann man solch einen Zwitter aus zwei Netzen herstellen und vor allem wie
mache ich das ganze?

Subject: ipfwadm forwarding versus paired input/output rules
Hi.
I was wondering if any firewalling gurus could please clarify for me:
what is the point of the ipfwadm -F forwarding rules?
It seems to me that everything that this ruleset can accomplish (except
masquarading) can be accomplished with a pair of
ipfwadm -I and ipfwadm -O rules. Could anyone please clarify this for
me?
As I understand it, -I rules look at a packet before it enters an
interface, -O rules determine whether it is allowed to leave a
particular interface. Do forwarding rules operate at the level of a
particular interface, or upon some kernel structure? If not, what is the
precedence of the rules.
A few weeks ago, I wrote something like
ipfwadm -I -a accept -S from_address -D to_address
ipfwadm -F -a deny -S from_address -D to_address
ipfwadm -O -a accept -S from_address -D to_address
and the packet still got through. This bugged me at the time, and I only
now have had time to get back to it. :)
tia,
Leon

I am new to Linux. I have set up a linux box using an old motherboard. The
system just works fine, but I am not able to set up the ISDN subsystem. I am
using an AVM Fritz card. I have used Suse's YAST configuration tool to set up
the system; the test of the card which is done during the setup runs perfect;
but I am not able to telnet to the Suse ISDN test access; just no response.
What can I do to identify the problem?
Thanks

Subject: Using Linux NIS client in Solaris NIS Domain
Date: Sat, 23 Jan 1999 19:00:44 GMT
Reply-To: [EMAIL PROTECTED]
HI,
I have a few linux machines (3 intel, 1 sparc) that I have just
started to play around with and want to setup for general use in a
small department - separate from the main IT section.
However I want users to be able to mount their homeareas from the
domain on to the linux boxes and also to be able to use the same
userid and passwds that they are used to.
I have looked around and read the NIS howto etc, and I'm still a
little confused and getting nowhere fast. It seems that our NIS domain
is using security (passwd.adjunct format) and that when I setup the
linux box as a NIS client, ie setup ypbind at startup, and set the
domain in /etc/yp.conf, I can do a ypwhich -m and it will list that it
can see passwd.adjunct but when I try to login to the box it fails -
I'm assuming that is due to the failure to pick up the passwd.
As for the setting on /etc/auto.master to allow me to use the
auto.home NIS maps, I seem to have got even less done here. Still a
bit confused about what the man pages are ttelling me. I'm including a
line like
/home yp,sun auto,home
Erm should this be in /etc/auto.master or should this be included in
another file that auto.master reads?
OK - but I'm not afraid to play around a bit more - no problem there -
I will but what I wanted to know was is it possible for me to get my
linux machines to particpipate as per normal solaris clients in the
NIS domain (ie someone out there has done it) or am I better off
turning one of my machines into a NIS slave, or even server, which in
some way gets the appropriate maps for passwd, passwd.adjunct,
auto.home from the solaris master and to use this as the machine that
the others bind to.
Yes, I dont really know what I'm talking about exactly, so sorry, any
and all help appreciated, and if anybody has some examples of working
setup it would be appreciated if you could give some pointers.
thanks,
ssd

Isn't too hard. Configure the Linux box to have dial on demand PPP. the 2.3.5
PPP version does this. Then set up the box to masqerade throught the PPP link.
This will change the outgoing addresses to the PPP IP.
Securitywise there isn't much to worry about beyond the standard stuff, like
checking the RH secuity pages and turning off any non-essential servies on the
Linux box.
Thanks about it. Hope this helps. There are PPP and Masquerading HOWTOs in
the standard places like http://www.linux.org.

Please don't simply make up IP addresses that do not belong to you.
Sooner or later this will cause problems. Use IP's in the range
192.168.x.x or 172.16.x.x (I forget what the 3rd range is).
Use proxyarp if you are on a LAN, however, in that case I would think
you would use IP's in that subnet. I use my eth0 IP for local IP.
In Windows you can tell if you are connected with 'winipconfig' (look in
\windows for the exact name), and in Linux you can tell with ifconfig.
Make sure \windows\hosts lists the Linux box and /etc/hosts lists a
name for each IP.
For an example see: http://www.xnet.com/~efflandt/linux/

Subject: Getting through the masquerade?
Date: Sat, 23 Jan 1999 19:39:19 GMT
Hi,
Our local university has just connected some of the living areas for students
close to the university to internet through 10 Mbit ethernet, which imho is a
really great thing to do. ;)
But the downside of it that they are using some kind NAT to masquerade all of
our ip-addresses.
I do however have access to real ip-adresses outside the masqueraded network,
and am wondering if it would be possible to tunnel the traffic to thoose
ip-addresses to my "behind that boring firewall" network.
If it hadn't been for the masquerading the task of tunneling ip-adresses would
be next to trivial, but now it isn't.
Is there some kind of software or magic setup thing that can open a
connection from my computers to a computer outside the firewall and then
tunnel back to me?
BTW, I have spooken to the admin on our site and they have no problems with me
messing around.
I have some spare computers with multiple ethenet cards, so putting up some
kind of router would be no problem.
Any suggestions would be welcome .... ;)

In the old days as a sufferer of Microsoft Wind-Uh-Ohs, I could easily find and
delete the
assorted ``cookies'' that would accumulate in the course of browsing the Web.
Now, as a fairly
recent and inexperienced Linux-user, I am not quite sure how to implement the
`find' command (or other) to locate and delete any accumulated `cookies'.
I would much appreciate anyone's help with this question.

Eric Raymond recognizes this as an important capability to add to fetchmail, and
has asked for assistance in adding Exchange capability to fetchmail. See
http://www.tuxedo.org/~esr/fetchmail/ for more information. -- the feature list
suggest that it might already have Exchange support, but the FAQ implies that it
may require convincing your Exchange administrator to enable POP3 support and
even make a slight Registry change. :-(
I think Eric was interested in folks who might use packet sniffers to capure the
client/server exchange and reverse-engineer the "native" Exchange protocol;
check the Web pages and if all fails, drop ESR a note.

Subject: Problem in using uugetty/PPP server
Date: Sat, 23 Jan 1999 19:11:39 GMT
Hi,
I had set up a "uugetty" deamon to connect my home linux PC to a remote
Linux station . I had successful set up a connection with the "uugetty"
deamon on my COM2 at my remote server. However, when I fired "pppd" at the
server (after successful connection with Minicom on my client end) , I fired
a "pppd -d -detach 19200 /dev/modem" (the same command line works with my
ISPs) . But the ppp connection never established ! I can conclude that the
problem is laid at my ppp server end where I might not be configured
correctly.How could I auto-fire a ppp connection after a successful "uugetty"
connection ? At the moment , I wish to find the way out with "uugetty"
instead of "mgetty" or "AUTOPPP" because I had problem compiling mgetty .
I added the line "local_IP:Remote_IP" in my option.ttyS1 file in /etc/ppp
but thing still doesn't work out. I appreciate any advice from anyone who
knowssomething about uugetty . :)
