Hi. I am trying to set up a simple network between one win95 machine and
my linux box.
I will use an internet connection on my box, and the win95 will use <gasp>
aol. anyways, I have gotten the ethernet card recognized, and can ping the
win95 machine....but when I try to dial the internet (kpp...KDE)...I
connect, but I somehow connect to my linux box ip number.(ifconfig for eth0
and ppp0 have identical ips) so there is no internet activity....can anyone
help with this problem....is it an etc/hosts.....hostname.....my isp gives
me dyn ip numbers.

I am having problems connecting to my ISP (IBM Global Network) under RedHat
Linux 5.1. I have gathered a small amount of information from IBM's
knowledge base on the subject and am still coming up short. I can get my
modem to dial in but get disconnected shortly thereafter (within a minute or
two). I don't think my username and/or password are getting passed on
correctly if at all. I am close but could use a little help. Has anyone
out there successfully connected to IBM Global Network under Linux and if so
could you spare a couple nuggets of info? Thanks in advance. -Lee

Actually, a better answer is to either hang up and let someone else use the
dial in line when you're not using your connection, or pay for the dedicated
connection you obviously want.
ISP's are already in a low margin business and they don't need greedy customers
stealing services that they aren't willing to pay for. (of course, I also get
royally ticked off at ISP's who advertise "unlimited" service and then use the
fine print of the terms of service to re-define the word "unlimited" to mean
whatever they want....)

So whoever was telnetting to my SMTP port, my IDENT asks that host and that
host is getting the response back? Geeez, I've been reading O'Reilly'
"Building Internet Firewalls" and it never did mentioned about that (nor of
IRC servers doing ths same thing) .... must read the RFCs.

Hmmm ..... So there's no way to identify between an incoming IDENT request (I
am the server) from an external host versus an outgoing IDENT request (I am
the client) where I am making a connection .... like different ports? I
better read the RFCs.

Subject: Re: Cable Modems
Date: Sun, 18 Apr 1999 04:52:51 GMT
I have an ADSL line which is 5 time faster than a cable modem, supposedly. I
recently read an article put out by IBM saying that the maximum download
speeds are: ADSL 2.5 Megabits/sec, Cable 512 Kilobits/sec, Dialup 56.6
bits/sec and the average connection times were: ADSL 2.2 Megabits/sec,
Cable 450 Kilobits/sec, etc. as you can see the ADSL and Cable modems are
exceptionally fast, but keep in mind that when browsing the internet your
downloads will only come as fast as the slowest link and if one of the
routers you end up going through happens to be bogged down then you are
S.O.L. The down/upload times are far faster still though and personally I
see no difference between the providers in my area, they are both
incompetent, the sales people do not know what they are talking about and the
billing departments are a bunch of putzes. After all this however i still
recommend the high speed connection as it make browsing the internet bareable
and you don't have to wait for all of those damn addvertisements to load!!
Performance has never been an issue. Any problems that I have had, have been
at my end. I have never had Telus, my ISP, go down on me.
Your computer will need to be outfitted with an ethernet card, cable modem,
and, aside form setting/changing your IP address, that is all you need. All
of the ISP's arround Calgary, and accross Canada as far as i know will all
supply you with a cable modem, for a small deposit.

A Web search will be hit and miss without the exact name
of the program. The "tcp_wrappers" package (actually, TCP Wrapper)
installs a program called tcpd. It's a shim that goes between inetd and
whatever daemon (service) is being called by inetd.
The archive for TCP Wrapper, Postfix, SATAN, and some other stuff
by Wietse Venema is at ftp://ftp.porcupine.org/pub/security/index.html
but get it from a faster mirror.
TCP Wrapper comes with many Linux distributions. You may have already
installed it.

Subject: HTTP PUT via TELNET port 80 Question
Date: Sun, 18 Apr 1999 06:41:40 GMT
I would like to download some data (norad two line element sets) from a NASA
website on a daily basis and have it automated. I would like to write a
simple script that runs as a cron job.
Can I do this via telnet and how do I set up the PUT command? I have to
enter a username and a password (which I have) to gain access to the data.
How would I format the PUT command to return my username and password?
Below, a dump of a GET of the login URL is shown.
I assume the PUT command I will use is something like:
POST http://oigsysop.atsc.allied.com/scripts/foxweb.dll/loginok@app01?
content-type: text/plain
content-length: 100
...
Any comments would be appreciated.

It's a Marketing thing. Right along with "All you can eat." Are you angry
with restaurants who advertise "All you can eat" when you can't walk in and
walk out with "All of their food." Or how about "Anytime, Anywhere."
Marketing departments are in the business of "redefining" words for their
own purpose. It's what they do.
If Marketing Departments actually understood the products they were
marketing they would, in most cases, probably have a high suicide rate
trying to sell "Really, Almost Working" products. How about "Nearyly bug
free" Software.
You didn't actually believe them when they said that did you? WoW it's been
along time since I've been that trusting. Imagine. Actually trusting what
you hear in an advertisement as being honest.
Sorry if I seem like am going off here. I have a cold and the "non-drowsy"
formula medicine is getting to me :-)

Subject: PCMCIA woes
Date: Sun, 18 Apr 1999 03:22:01 GMT
I'm sure this is something braindead, but I am just completely stuck.
My problem is this: I'm running a Gateway Solo 9100/150mmx with a 2-slot
pcmcia port. I'm also using a commwave generic 33.6 modem and an NE2000
network card, poth in pcmcia form. Under RedHat 5.1, after a little messing
around, everything worked flawlessly. Naturally, when I had the chance, I
upgraded to 5.2/kernel-2.0.36/pcmcia-3.0.5 and ruined it. Both cards are
recognized. The modem initializes with settings 3f8/irq4 (com1), but for some
reason is not accessible via chat or minicom to /dev/modem, /dev/cua0,
/dev/ttyS0, nothing. statserial /dev/cua0 gives a full normal (as far as I
can tell) reading, with RTS and DTR reading status 1, and all 10 lines
reporting present, but I can't dial the &@#% thing. The NIC does not
initialize at all, but fails every time due to an IRQ conflict on, you
guessed it, IRQ4. So anyway, I upgraded to kernel-2.2.5/pcmcia-3.0.9, and I
have the same problem. I'm thining the problems must be related.
Before I wipe the drive and go back to RH5.1, does anybody have any ideas on
this? I'm totally out of ideas...
Thanks in advance,
Rudy

It should be a vanilla installation with one exception: create a
wildcard entry in smtproutes that points to Earthlink's SMTP server.
Like this, presuming that Earthlink's SMTP server is smtp.earthlink.net:
echo ':smtp.earthlink.net' >/var/qmail/control/smtproutes
For mail coming in, just use fetchmail.
