Hi all,
I got my PPP connected lately. Having tried to use that, found the data
downloading speed is extremely slow, varying from 35 to 350 byte/sec
even though the connection rate at 50600bps. If I connect by using
win98's ie5, averagely I get 2.8kbyte/sec.
Another question about netscape is why its graphic resolution is not as
appealing as win98? I'm using Nvidia RIVA TNT 16meg Video ram, and had
setup X-server with RIVA TNT driver. It seems X-server does not fully
making use of the resources ;-).
I believe Linux can do as good as win98 or even better. It is just my
ignorant on these issues.
Would anyone help me.
Rgds,
Nixien

I am unable to solve a problem with DNS. I have tried and tried and
no matter what I do my telnet session from a Windows NT PC cannot
see my nameserver. It can see the IP address fine but not my name-
servers DNS name.
I have used the O'Reilly book 'DNS and BIND' to setup everything.
'NSLookup' with respond back with the proper information about oracle1
but from what I have read NSLookup does not use 'named' to lookup
info so it is not a true test.
My configuration is as follows:
============================ etc/hosts ===========================
127.0.0.1 localhost localhost.localdomain
192.168.200.2 oracle1.diodesign.com oracle1
========================== etc/host.conf =========================

/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};

You can get online right now by manually configuring yer eth card. Then screw
around with dhcp later if u want. I cannot for the life of me get connected
to my dhcp server so i gave up and consider my cable service a static
connection.....
ifconfig <ip address> netmask <netmask> up
route add default gw <home's gateway> netmask 0.0.0.0 metric 1
and add home's name servers to /etc/resolv.conf

Yes, the information is sent with the headers.
Here's how it works:
What you have to do is send an extra header along w/ the request.
It's like this:
Let's say the URL is http://www.somehost.com/private/file.html
and the user is `rene.bauer' and the password is `secret'
First, encode the user/password as such: `rene.bauer:secret'
Then, base64 encode this string: cmVuZS5iYXVlcjpzZWNyZXQ=
<CAVEAT!>
(base64 encoding... Is kind of beyond my DESCRIBING it to you, but I'll
attach some source at the end, to base64encode and decode...)
(It's stuff I just hacked together now, and it's not anywhere
NEAR bullet proofed, so, be warned, it's JUST for illustrative
purposes... I'd suggest looking up source for real base64 decoders.
(Just, mine is probably simpler when you're just trying to figure it out...)
</CAVEAT!>
Then, what you do is you open a connection to www.somehost.com port 80
and send
GET /private/file.html HTTP/1.0
Authorization: Basic cmVuZS5iYXVlcjpzZWNyZXQ=
And, that's how "Basic Authentication" is done...

Date: Sat, 10 Jul 1999 04:45:03 GMT
I was in the shower today, and i got this crazy idea that it would be
fun to get a few friends together, and start a local internet type
network, but completly off the the real internet, maybe there would be
gateways and such to get on to the internet though. I have been using
linux and the internet for a few years now, and although im not a
hardcore hacker(the good kind), I know quite a lot. I understand TCP/IP,
DNS, arp, and stuff like that.... but there are still a lot of things
i need to know, like how to go about assigning IP address's to a umm,
well
say someone was calling up my computer and connecting via PPP, im not
sure how to give them a couple of IP address's to use for there own
computers. what do ISDN connections use, is that PPP also or something
else? how about ADSL, could i buy an ADSL modem thingie and connect
to another computer who also has ADSL? or does the local phone company
have to have something special setup? i dunno, i got a lot of questions,
im going to go look for some good RFC's but there are so many of them
and then there are at least 10 RFC's for eatch topic, I think im gonna
be wasting a lot of time looking for the good stuff. im also about to
go browse throug the linux faq's and how-to's.. but I guess what im
asking is just for any good info anyone thinks i should look at, any
good books on starting up a tcp/ip network using *nix. any real good
RFC's, any good websites that explain networking real good... anything.
Nick
p.s. Yes, I realize this could cost a lot of money, and I might be
crazy, and I will probably never do it, but it sounds fun. so for now
im gonna try to learn everything about it i can.
p.s.2 I will try to read this newsgroup to look for responces, but I
would like it if you could send responces to my email address at

Does anyone know if it's possible to set up Netscape so that it will

I have searched "freshmeat" an dother sites to no avail.
Also; Whenever I insert a "link" in a message and click "Apply", then
clicking "OK" causes Netscape to crash! Does anyone know what causes
this and if there is a fix?
