Well, the reason you're getting DNS errors is simple: when you have no
connection, netscape attempts to look up the hostname of the web page
to get its IP (i.e. to translate www.netscape.com to 153.68.37.6 or
whatever), but since the network link isn't up yet, it can't do that.
If your modem is hanging up immediately like that, there's almost no
chance that it is actually getting a ppp connection at all. I suggest
you read the ppp-howto and follow the instructions for connecting
manually. (note that you should find out if your ISP uses PAP, CHAP or
a login authentication, since they all require different setups).

Date: 6 Apr 1999 16:53:20 GMT
Hi,
I.m having a verry frustating experience with a RH 5.2 and a ADSL modem.
The ip is static.the netmask is 255.255.255.248
Both cards are recognized at boot time.
I can ping both of them and I can assign ip on them.The cards are working.
The ADSL modem is *.* 218.97
In win95 I don't have any problems conecting by specifying this ip as
gateway.The connection is ok.
Now the problem :
I have like this
*. *. 218.99 - eth0
192.168.2.14 - eth1
route
Destination Gateway Genmask Flags Metric
Ref Use Iface
*. *. 218.96 * 255.255.255.248 U 1
0 eth0
192.168.2.0 * 255.255.255.0 U 0
0 0 eth1
127.0.0.0 * 255.0.0.0 U
0 0 0 lo
default *. *. 218.97 0.0.0.0 UG 1
0 0 eth0
If I do a ping to *.*.218.97 I have an answer so the cable to ADSL modem is
working BUT if I try to do a ping to an ip somewhere on the net (lets say
the ip for bell or netscape) I have no answer.None.Not even the message
network unreacheable.
I tried also by specifying the default to *. *. 218.99 but nothing.
I don't know what else to try .
Thanx for your time

Why not just install DNS and be done with it? You need to edit
/etc/named.boot and create or edit files in /var/named. You can find out how
to edit these by reading /usr/doc/HOWTO/DNS-HOWTO if you have one, or by
going to http://www.digitalvoodoo.org/LDP/HOWTO/DNS-HOWTO.html. DNS isn't
all that hard to get up and running, and it'll be good experience for you.

I want to route between two subnets in my building to speed up resource
sharing between 2 differeny companies. Both are connected to the internet
independently. I want to be able to route to the other subnet without taking
the 20 or so hops through the internet to get there. Do I need another
network card to accomplish this or is there a way to do this with adding
another network(alias) to the same network card and then connecting our
hubs together??? Any help will be greatly appreciated. I will be glad to
provide any extra info if you need it to help. Later

When sendmail is slow to start, and other services as well (typical timeout
3 minutes or so) it usually means a DNS problem - usually your inverse
address lookup which isn�t configured correctly.
If DNS is configured correctly, you should be able to do, FOR each of the
systems in your network and ON each of the systems in the network:
nslookup <hostname of system>
nslookup <IP address of system>
Also, nslookup loopback, nslookup localhost and nslookup 127.0.0.1 should
work on every system
If these fail, you have found the problem, and you should check the DNS.
Another solution is simply not to use DNS at all, and just fill out
/etc/hosts correctly and copy it onto every system in the network. DNS
inverse addressing can be pretty hard to set up. Read the documentation
carefully!

Subject: 1 IP address, 2 machines
Date: Tue, 06 Apr 1999 09:57:59 -0700
I have a DSL with 1 IP address. I also have 2 machines. One is a server
that needs to be accessible from the outside for telnet, ftp, http. I
also have a machine on the inside that is just for outbound (private
network to internet) connections.
My question is how exactly do I use masquerading so that requests to the
server from the outside reach the server (for cisco, this would be a
static address (map of external to internal addresss), while being able
to make the outbound connections from the other machine? In my mind, you
can only map that 1 real IP address to the server, and will not be able
to surf out because all calls to all ports of that IP address will be
mapped to the server.
Someone please tell me I'm wrong, and that there is a way to do this.
Thanks,

Absolutely not -- each IP address must be unique, unless you're running some
very strange routing software. :-)
What you're probably trying to do is called IP Masquerading, and you probably
want to set your eth0 network segment to be in 192.168.0.X -- that's a fake
network used for exactly this purpose.

Easy solution:
Try <shift>+<PgUp> after booting. This brings back the offscrolled
lines.
Other possibilities are the command dmesg or the file (if
exist) /var/log/boot.msg.

Subject: Can Sendmail/Fetchmail do what Pegasus does?
Date: Tue, 06 Apr 1999 16:41:41 GMT
Reply-To: [EMAIL PROTECTED]
I have recently installed slackware 3.6 on my PC and I am eager to
start sending/receiving mail from my linux box (I connect to my ISP
through PPP).
I am used to Win95 mail programs such as Pegasus Mail and Outlook
Express with which I can connect to free e-mail servers (iname.com,
softhome.net, etc.) and easily download my pop3 mail (from my free
account at the server) and send via smtp using the server as relay
host. All it takes is that I click on user's options and set :
1) pop3 server; 2) pop3 username; 3)pop3 password; 4)smtp server for
each account.
I currently have e-mail accounts with 5 different servers, all with
different usernames and all managed from a single installation of
Pegasus Mail.
My question is: can I use my current installations of Mutt (MUA),
Sendmail (MTA), Fetchmail and Procmail to do the tasks that were
previously done with Pegasus?
So far I have been able to download pop3 mail with fetchmail from one
account (but have no idea as to how I can setup Fetchmail to retrieve
from my other four pop3 accounts and place the retrieved mail in 5
different folders (one per account).
However, the biggest puzzle is Sendmail. I have read all I could find
on its configuration setup in the docs and in the newsgroups, and have
experimented with the sendmail.cf file, but have so far gotten very
poor results (I am still unable to get my mail sent out).
I have added in my sendmail.cf:
#my official domain name
Djwww.bogusname.com
# who I masquerade as (null for no masquerading)
DMmyISP.net
# "Smart" relay host (may be null)
DSsmtp.oneofmye-mailservers.net
My /etc/resolv.conf file:
search .
nameserver NNN.NN.NNN.NN
nameserver NNN.NN.NNN.N
(where the N's stand for the actual numbers).
My /etc/hosts file: 127.0.0.1 localhost
0.0.0.0 roderick
When I run 'sendmail -q' sendmail fails and I get an e-mail titled
"Mail Delivery S (48) Returned Mail:
Data format error" which states "501 <[EMAIL PROTECTED]>...
Sender domain must exist."
How do I do it right, and is it possible to configure Sendmail for
five different relay host accounts?
Would anyone be knowledgeable enough to give me some specific advice
or direct me to some docs that explain in simple terms how to get
things right?
Thank you very much to all who will respond.

RH 5.2 ships stock with telnet enabled, unless you purposely disabled it in
/etc/inetd.conf and /etc/services. Just set up some standard user accounts
for the folks who you want to be able to telnet in to your machine, and let
them know about it. Then keep a sharp eye out for hackers with rootkits and
other fun things that can destroy or otherwise abuse your system.

Subject: Re: How to set the NIC parament in Linuix?
Date: Tue, 06 Apr 1999 12:40:29 -0700
Usually that's autodetected; most of the Intel NICs are supposed to switch
back and forth. I would guess that perhaps someone set it with a Windows
utility to only speak 10MB. If you have a Windows box available, you might
try changing its settings back to autodetect.
I went and looked through the eepro100 source. I'm not a fluent C programmer
by any means, but it appears to me that the driver should autoswitch between
10 and 100 without any effort on your part. It appears that the driver is
clever enough to change media types even during normal operation -- that is,
you can hot plug it back and forth between 10 and 100 speeds and the driver
should figure everything out and keep things working without a reboot -- if
the board is working properly. If it's not switching, then it may have been
disabled. See prior paragraph :-)
You might also have substandard or defective cabling.

This should be the right way to export your filesystem.
But did you restart the nfsd daemon? Usually you have
two possibilities:
You can call the program exportfs to export the filesystems. But
in most cases you won't have such a program on your linux box...
The other way is determining the PID of nfsd and send a -1 to
this process. After this you should be able to mount the filesystem
by the other machine:
mount 192.168.1.1:/ /mnt -o ro

problem is as folows:
2 cmputers conected with a modem. (Home and work)
large files have to be transfered betwen the two computers.
normaly the file is transfered some smal changes is done and the file

so the files are nearly identical and the files lives on the two

folowing colud be done make a diff file of the two versions and send
only that.
Smaler amount of data equals lower connection time.
Q is ther a system already that have this build into it? so that I
only have to tel the system what to send and it negociates what have
to be in the diff file and sends that.
or is the only way to use diff and send it an patch it by hand.

A collision is the result of two (or more) computers trying to
transmit packets at the same time. An incorrect NIC driver will not
cause collisions, it just means that some features of the card are not
available (if the card works at all). You might want to look up
CMSA/CD and Contension Based Media to find out about collisions.
