Hi Glenn,
I'm still trying to get PPP scripting to be 100% reliable, but
hopefully I can help. Fist off, can you establish a solid
connection by using something like minicom? I went
ass-backwards and tried to get scripting to work first;
spare yourself the same misery.

I am trying to get an AsanteFast 10/100 ehternet card to work I don't
know which driver to use and what settings to try.
I did find an article that implied that the tulip driver would work, but
when I loaded it, it failed. Does anyone have experience with this
card?
Thanks,

hallo!
i've heard that when you've got a 10 MBit network, than it's faster to use a
twisted pair connection than a coaxial one.
because the twisted pair is bidirektional you can transfer 10mbit in both
directions at the same time.
is this correct?
please answer me! (also per email please)
thanx in advance,

Nicholas,
Is that all it takes? I would imagine that Internic would want one to
provide the ip-address & hostname of the server that is authoritative for the
domain. And since the original poster did not want to run DNS himself, I guess
that would mean that his ISP has to run DNS for his domain. Am I right?

Subject: Help wedging in a firwall (2.2 kernel)
Date: Sun, 13 Jun 1999 13:04:20 GMT
I call it wedging in because I can't reconfigure the router to change
where it pushes by default.
Current Setup:
|------------|
| Internet |
|------------|
|
|-------------|
| Router |
| 192.10.10.1 |
|-------------|
|
| <------------ Wedge point
|
/|\
/ | \
|----------------|
| Internal Hosts |
| 192.10.10.* |
|Default Gateways|
| 192.10.10.1 |
|----------------|
I would like to wedge in the firewall in between the internal hosts and
the router without having to reconfigure everything. Then using
IPChains, I could choke down on the addr/ports as required.
Firewall is RH5.2 [2.2 kernel] 2 NIC's.
Since I can't force the router to send all packets to eth0 on FW, I
think I need to alias eth0 to all the internal address.
Q: How do I alias all the ports on eth0, then pass that info out eth1
to the device with the same address? Can this be done?

Subject: PPPD daemon dies under Enlightenment/GNOME 1.0 (RH 5.2)
Date: 13 Jun 1999 14:30:43 GMT
I just installed GNOME and Enlightenment (under RH 5.2). Everything seems
to be working except the PPP (found under Internet in the main menu).
After clicking connect my modem does its usual screeching/clicking.
Eventually, the status window says "PPP connection established." ~10
seconds later my modem shuts off and an error window saying "The PPPD
daemon died unexpectly" appears. If I try to quickly ping sites before
the modem shuts down, it gives the old "host is unknown" message.
The strange thing is that PPP works perfectly if I use the old network
config area from my original RedHat 5.2 install (which is now under
"anotherlevel menus -> network config" in the gnome main menu config). As
far as I can tell the setups are the same (same DNS servers,
username/password ect). Any advice would be greatly appreciated :)

Subject: Re: 100MB Fast Ethernet ISA ??
Reply-To: [EMAIL PROTECTED]
Date: Sun, 13 Jun 1999 14:33:14 GMT
ISA isn't anywhere near fast enough to keep up with 100Mb ethernet. 3Com
made a ISA 100Mb card when 100Mb first came out, but I'm pretty sure they've
discontinued it since. They made it purely to allow ISA machines to
participate in 100Mb networks (although the performance was barely more than
10Mb cards). The introduction of switches and switching hubs made such
cards unnecessary. The cards were pretty expensive anyway.
But before you consider 10Mb to be too limiting, you might want to consider
that 10Mb is over a Megabyte per second and that 100Mb is faster than most
modern hard drives. Are you really using that bandwidth for your little
home network? Also, if you ever get a cable modem or ADSL connection,
they all use 10Mb ethernet.
The preferred way to connect them nowadays would be a switching hub. If you
want the cheapest route, that would be to put a second NIC in your main
machine, hook it up to a 10Mb hub and set your main machine up as router.
You can get a 5 port 10Mb hub for under $20 if you shop around.
I can't comment on the ping problem, but .5ms would be the typical ping time
for 10Mb ethernet. 100Mb ethernet should theoretically be less than .1ms,
In actual practice, you'll be CPU/bus bound to something under .2ms.

bv,
The answer is that you have to set up DNS for your domains. This involves
installing the 'bind' software and configuring it. Be warned that this is not a
trivial task and you will have to do a significant amount of reading. It is
really not called for on your small network unless your intention is to learn
about DNS. There is a HOWTO available for this I believe. And there also is an
excellent book from O' Reilly : "DNS & BIND" (go for the 3rd edition).
As pointed out, the other alternative is that you put the hostname to
ip-address mapping in your /etc/hosts file. This is a lot faster to setup and
is easier to maintain on a tiny network. However, it is a horrible solution for
bigger networks.

This doesn't sound like a masquerading problem at all, but rather
one with your e-mail client. Does it do the same things (hang) whilst
using FTP? You say that it doesn't when fetching large WWW pages.
I'd take a hard look at the mail client. Failing that, I'd be
tempted to deploy fetchmail on the Linux box (connected directly to
your ISP), pull mail from the ISP to that system and set up a POP
server on it and pull the mail from there with your client.
Good luck with it!

Date: Sun, 13 Jun 1999 16:41:31 +0200
Hallo,
obiges Problem habe ich, netstat -r zeigt mir default auf meinem Gateway
(eth0).Wie zum Teufel trage ich das denn in netcfg oder linuxconf ein?
Bitte helft mir, aber einfach beschrieben - sonst raffe ich das nicht
:-)
( Bin bisher "Windozer", da geht das "einfacher"!)
Eine Verbindung baut meine ISDN-Karte auf, hält diese auch, findet aber
das große Netz nicht.
Auch folgender Versuch funktionierte nicht:
isdnctrl addif ippp0
isdnctrl encap ippp0 syncppp
Antwort:
/dev/isdninfo: Kein passendes Gerät gefunden
Bei diesem:
/sbin/route add default ippp0
kam:
SIOCADDRT: Kein passendes Gerät gefunden.
Ich bin mir sicher, daß es sich hier um einen Konfig Fehler handelt,
weiß aber nicht wie ich ihn beheben soll. Ach so - benutzen tu ich
RedHat 6.0 mit Kernel 2.2.9 und die ISDN4LINUX FAQ konnte mir leider
auch nicht weiterhelfen.
Vielen Dank!!!

It's sorta true. What you're talking about is called full-duplex ethernet.
Many 10Mb cards don't support it, although almost all 10/100Mb cards do.
To do it, you'll also need to connect all your machines to an ethernet
switch capable of full duplex (most are). Using a regular hub forces
everything to run at regular half-duplex. The cost of the switch usually
makes this arrangement unreasonable.
I'd recommend twisted pair, but not for reliability and flexibility reasons,
not for performance.

Absolutely no sense at all.
You might get some insights into connecting from this URL:

It's my personal opinion that manually dialing in and then starting pppd
is not a good idea despite the PPP-HOWTO. Others think differently and
they are entitled to their opinion too.
