Hi,
I wish I came to this thread before my newserver expired the original
question....
I also have a laptop that I use to connect to a number of different
networks - some use dhcp, some don't. I want to be able to easily
switch network settings so that I can easily connect to any of them.
That part isn;t too hard, althoug I've only done it once - in the next
few days is when I'll really be doing more swithing. But I suspect my
hardest piece will be getting mail right.
I'm using fetchmail to pull mail form various servers - I just put in
all the servers I need and if some time out - so what. But outgoing
mail seems pretty tough. In once place I need to do some "heavy"
masquerading, so I make the appropriate sendmail.cf changes, also the
*comps files in my nmh files, but I still think I'm having trouble with
sendmail.
THis is the distributed sendmail with rh6.0 - I may go to a "real"
source distribution - I'm having trouble with relaying - every time I
email to a new domain, sendmail says that relaying to that domain is
refused - probably has to do with the fact that I'm masquerading.
Anyway, Id love to share experiences moving from network to network on
a regular basisand particularly mail issues in that situation.
Cheers,
/ Sid /

I recently got some tips from dansgold about setting up my home net.
with NFS and Samba... this also brought on some more questions:
What I really want to do is a test run between my Win95 & linux box to
see if I can get them talking using TCP/IP. If I can then get NFS and
SMB going, I'll switch over the cable modem over to the linux box and
use it as my firewall/proxy.
SETUP:
1 Pentium 100 linux box with a Linksys PCI NIC using NE2000 driver ip
192.168.0.1
1 Pentium 166MMX ip 192.168.0.2 with Linksys PCI NIC & SMC NIC connected
to Cybersurfer WAVE cable modem via VIDEOTRON cable services
1 4 port hub connecting the pcs
1)I can ping the "localhost " and 127.0.0.1 on each machine;
2) can also ping the host ip address itself, but can't ping the other
box that's across the hub...it's as if the ping command was frozen, if I
do a CTRL C, it shows 100% packet loss;
3) the localhost on the Win95 pc seems to be linked to the SMC card
which is connected to the cable modem;
4) dansgold had suggested to me to take the cable modem and attach it to
the hub; fine...but because my ISP uses DHCP how will the modem know to
whom to assign an ip to in this case (random or both or neither???);
5)my subnet mask is 255.255.255.0;
I've read several HOW-TOs on TCP/IP, ETHERNET but am still a little
lost. I've gotten a little help as well, but not sure if I'm forgetting
something in my net.'s config...
NOTE: does route, subnet on linux and Win95 pc have any bearing on all
this???

# Secrets for authentication using PAP

In your /etc/ppp/pap-secrets file, I would try something like:
user * mypassword *
where user = your login name on remote system.
mypassword = your password on remote system
pap-secrets should have root/root 600 permissions.
I'd like to know if this fixes it.

I think you may be overthinking this problem.
I have three 3c905b cards in my Linux box which have been successfully
autoprobed with IRQ 10 (all of them share the same IRQ) and various base
addresses under RedHat 5.0, 5.1, 5.2 and now 6.0.
Make sure you have 3COM cards and 3c590/3c900 "Vortex/Boomerang" support
compiled into your kernel. Also make sure nothing else is using IRQ 10.
Check this in /proc/interrupts.
It should show up at boot time like this:
eth0: 3Com 3c905B Cyclone 100baseTx at 0xfc80, 00:10:5a:9e:9a:3f, IRQ 10
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
MII transceiver found at address 24, status 786d.
MII transceiver found at address 0, status 786d.
Enabling bus-master transmits and whole-frame receives.
Hope this helps.

Hi,
I'm new to pppd. Previously, when I type pppd, the response is OK. But
now, when I type in the same command, the response is in the form of
characters which looks like garbage to me.
Nevertheless the connection to my ISP was established when I use eznet.
But the problem is DNS lookup is extremely slow. In addition to this,
the web pages weren't displayed at all.
Please help. I'm currently using Redhat 6.0

Date: Fri, 04 Jun 1999 22:58:27 +0200
(please read this message with a fixed font)
You should only do it if you intrested in learning about routing policies,
subnets, etc. And I mean this in most possible way :)
You will need a third(!) 10mbit nic to connect de laptop with linux box.
The NT box and the laptop will be on a seperated subnet, linux on both.
You should use ipchains/ipfwadm to setup forwarding between NT and laptop.
Setting up smb file/printer sharing between these two subnets is quite tough,
especially setting up browsing correctly.
cable modem -----10mbit--- linux -------100mbit crossover-------NT
|
10 mbit hub
|
laptop
Alternative, you could plug the new 10mbit nic into the nt box and enable
forwarding on NT.
This might be prefereble if you do not require direct smb file/printer sharing
between linux and laptop.
cable modem -----10mbit--- linux ---100mbit co------ NT --hub-- laptop
However I do not recommend putting the laptop on the same subnet as cable modem.
The big question is should you do it?
- Well an extra 10 mbit nic and cables shouldn't be too expensive,
make sure you use a cat 5 crossover tp cable between NT and Linux
- It might be faster if run large graphic apps or games on the linux box.
But I don't think you will notice much.
However, if you are curious if will work and want to know how to set it up, try
it, the most trouble is having the laptop play along.
Good Luck!

I've gotten to the stage where I trust my linux box more than I trust my
provider. Last week I suddenly disappeared off DNS.
But did I suspect my box? NO WAY - first thing I did was check my provider,
and sure enough their nameserver had hiccupped.
Linux very rarely breaks, once your box is set up it's more productive to
start checking external factors if something goes wrong. (My last server
reboot - which was only because I was checking a problem which turned out
to lie with my provider - was on May 13 at 13:09:28. It's been continuously
running since. In the interim I have added and/or changed so many files and
settings on that server, it's not funny).
