Apparently your machine does not have a valid internet domain name. You
might get more help for that topic on a newsgroup related to your mail
program (sendmail?).
Mine works by default, but I have a real IP and hostname (I am just
posting from here because our news machine went belly up).

One problem that you will have regardless, is that you cannot simply make
up any IP addresses for your LAN. They need to be in the private address
ranges. See the NET howto and search for PRIVATE.

Subject: Problem with KPPP
Date: Sun, 06 Jun 1999 23:10:16 +0200
Hi there,
I recently bought Linux (kernel 2.2.5), and I'm using the KDE Desktop...
When I try connecting to my ISP with KPPP, I get an error message:
"Sorry, but KPPP's helper just died. Since it would be pointless to
continue, the process will be terminated."
If I restart KPPP and connect again, it connects flawlessly. BUT if I
shut down X11 and restart it again, starting up KPPP results in the same
error the first time. Restarting KPPP connects normally again. Is there
anything I can do about this? It's not serious (I think), but it's just
an annoying message.....
and I have to click twice to get on the internet :-)
Any help would be appreciated
Dennis

I've never connected the chain to anything. the BNC connector supplies
sufficient grounding IMO.
I always thought the chain was placed there as a tether...

Subject: Internet access and IP Masquerading`
Date: Sun, 6 Jun 1999 15:03:42 -0700
Basically I have Linux setup for IP masquerading, and it works fine. 3
Win95 boxes can share the dsl line with no problem. What I want to do is
keep users that don't have a valid account on linux from being able to
connect. I have Linux setup with SAMBA to take domain logins, and this
works great for file sharing. If users don't login, and just hit cancel,
they aren't able to use some of the programs, like office97. I would like
to keep users from getting access to the net unless they login. Is there
anyway of doing this? Can someone point me in the right direction?

Usually 1500 mtu is default. Smaller mtu (and mru) only help if working
with many small files (or maybe if you telnet alot)..

Aeh, ich hab's so verstanden: ein default-gateway ==> ein Router
bzw. mehrere def.gw ==> mehrere Router

Mir geht es nicht um Kompetenzgerangel, sondern ganz einfach darum, im

Hello,
I was wondering if anyone has a suggestion for a
'free' (GNU licensed?) firewall product similar to
TIS Firewall Toolkit. I would like to change from
the TIS product due to it's commercial
limitations. As a consultant I can't 'support' the
TIS product unless I go for Gauntlet (and even
then I'd have to examine the license).
Basicly, I'd like to get a publicly licensed
product that I can utilize freely (both
commercially and privately), provide commercial
support for if I choose, and develop along with
the rest of the internet community to ensure it's
longevity.
I believe this proposal should be well accepted as
it embraces the very core ideals of OSS.
If anyone has info, please let me know.

Subject: diald and manual connections
Reply-To: [EMAIL PROTECTED]
Date: Sun, 06 Jun 1999 18:05:40 -0400
I have diald set up to connect to connect to my ISP for normal
connections, but I also have other manual connections (typically using
ifup or usernet in Redhat). The problem is that diald's psuedo slip
connection interferes with pppd's defaultroute for manual pppd
connections.
Sending a 'block' to diald's fifo does block diald, but does not remove
the routing. Is there anything short of killing diald that would bring
down its routing temporarily? Somehow when diald brings up pppd, it puts
the ppp default route before its psuedo slip route. I guess I will have
to experiment to see if I can do what it does just using '/sbin/route'
(from /etc/ppp/ip-up.local)

If you don't or can't get the patch, simply install dhcpcd and replace
/sbin/pump in your if-up script (I think that's where it was) with the
apropriate dhcpcd command. It worked for me.

Ok, my question is (I suspect) quite simple. I have a 3-node LAN, but
the server is buried away in a corner. How can I put an audio CD into
the server, and play it (i.e., have the music heard) in another room ?
If I try to export the CD, it needs to be mounted. If I don't mount
it, then my host can't see it.
Another question: I plan to put four speakers onto my sound card. How
can I set cron to play a CD at a particular time?
Thanks.

Subject: Connecting to the Internet.
Date: Sun, 6 Jun 1999 19:10:35 -0400
I just set up Redhat 6.0 and installed all options...I'm brand new to the
world of Linux (experimenting) so perhaps someone may have experienced this
before. I've done nothing with this system except attempt to connect it to
an ISP.
My first Linux Task:
1.Connect to the Internet.
Using Gnome I browsed through the menu's.
KPPP Seemed like the easiest method to connect.
My ISP has me choose a terminal setting to log in...where I type in my
username and pass. Type in "ppp default" and continue.
My modem dials no problem...and the login script debug windows shows that my
ISP has assigned an IP address.
Suddenly an error window pops up with this message.
The pppd daemon died unexpectedly!
Details:
Jun 6 18:53:14 localhost pppd[693]:pppd 2.3.7 started by root, uid 0
Jun 6 18:53:14 localhost pppd[693]:Using interface ppp0
Jun 6 18:53:14 localhost pppd[693]:Connect:ppp0 <--> /dev/ttyS1
Jun 6 18:53:14 localhost pppd[693]:Warning - secret etc/ppp/pap-secrets has
world and/or group access
Jun 6 18:53:28 localhost pppd[693]:Hangup (SIGHUP)
Jun 6 18:53:28 localhost pppd[693]:Modem hangup
Jun 6 18:53:28 localhost pppd[693]:Connection terminated
Jun 6 18:53:28 localhost pppd[693]:Connect time 0.3 minutes.
Jun 6 18:53:28 localhost pppd[693]:Exit
I believe my problem lies in pppd not negotiating communication properly.
I've also manually connecting following the instructions at
http://axion.physics.ubc.ca/ppp-linux.html my modem appears to work fine.
The log files from the instructions at the site above show nothing about
pppd. Even though it says it should var/log/ppp should reveal info about
the type of login.
I've confirmed that the kernal is set up for ppp and that pppd exists.
I'm new to linux, but not to computers I've spent about 7 hrs trying to get
connected so far... and I'm etremely frustrated.
PS. I appropriately added and removed the lock option. Other than the
configuration instructions at the site above...I've made no other changed to
my system...perhaps I should?
Any guidance would be appreciated.

Hi everyone - I'm sure you're all sick of answering questions such as
this...but anyways..
I'm running RedHat 5.2 on an i386 machine, and had been using KDE v1.1
for some time... The KPPP program was fine, and connection to the net
was no prob...Anyway I finally got sick of KDE's clunkiness and changed
to Gnome (and no flames about Gnome's supposed instability thanks!) ..
Gnome/Enlightenment is great, but I am no longer able to connect to the
internet..
I have tried several connection programs (including EzPPP and GnomePPP)
and _every_ one of them dials out, connects, sends login/password, and
then hangs up and reports that the "pppd dameon died expectedly..".
Obviously it is a prob with the pppd/dial program, but I'm not sure
what...
As I said, it was fine with KDE, but not under Gnome....I know I haven't
provided much info but I'm not much of an expert on networking, and it's
probably a common problem....Any suggestions to try out would be
appreciated, or failing that, if someone can tell me how to provide the
relevant details I will get more information...
