Subject: is having 2 default routes ever supported?
Date: Tue, 07 Sep 1999 20:19:44 GMT
Can there ever meaninfully be 2 default routes?
1) Most of the man page language refers to the default route in the
singular.
2) I have seen routing tables that contain 2 default route entries
I have assumed in those cases that one entry was a non-functioning,
garbage residue from some irregular manipulation of the routing table.
Am I wrong? A client switched to DSL from analog modem but has both
interfaces up at the moment. Has in mind keeping it that way in hopes
that if the DSL interface returns some error when a packet is routed
to is "as the first default route," the routing software would direct
it to the analog modem outlet to the other ISP as the "second default
route."
Idea never occurred to me. Surely it doesn't work that way, or... ??

That would be fine, except that 'pppd' on demand is a bi too sensitive;
it will bring up the line on _any_ packet, and keep it up if there is
_any_ packet going thru periodically.
That can be pretty costly, especially if one has a Win9X based network,
as one really wants to ignore a number of packet types, boht outgoing
and incoming (firewalling rules might also be used, but that's more
complicated).

I just thought it rude. But, before I open my mouth I did some research. If
you take some of the tools written mainly for the MS/IBM world they start off
with the cursor at the top of page (after the quoted data). Tools written
mainly for UNIX start of at the bottom (the quoted data and then space for you
to enter data) So, those users using certain 'tools' feel themselves superior
and arrogant enough to insist that their standard is the only standard. Just
because 'their software' allows them that option. Either at the top or the
bottom. I have just spend half a day trying to find the 'switch' in Netscape
to start capturing data at the top. If it is there, it is well hidden that
no-one should find it. If it so, that is another Linux based product I don't
use. I like the top. I am still trying though find in the FAQ for this
newsgroup where it says the top or the bottom. If it is not there I still
think it pure arrogance to insist someone do it!!!

Subject: Re: Multi-ethernet config at boot strange problem...
Date: Tue, 7 Sep 1999 13:23:01 -0400
I had a similar problem trying to use two ISA NE 2000 compatible cards. I
could only get one to work - the one whose io address was defined as eth1
was being used as eth0. Whenever I went back into linuxconf, it had the
same io address for both eth0 and eth1.
Then I saw a post that suggested that the options line in /etc/conf.modules
needed to have the io addresses for the two cards separated by commas. I
tried putting both io addresses separated by commas on the io address line
in linuxconf for both eth0 and eth1. If you subsequently check
/etc/conf.modules you will see something like:
alias eth0 ne
alias eth1 ne
options ne io=0x300,0x320
If you must also specify the irq, then follow the same technique - enter
both irq values separated by commas in the irq entries for both ethx
configurations.

You need to read how-to from redhat CD.
1 ipchains how to. this will teach you to route data from server to your
pc. let your pc to access homepage and email......
2. sendmail.cf need to modity it.
3. http.conf need to modity it.
you must take time to read the how-to from the CD.
I total spend one month to read the CD & book to success to setup the
server.

For AOL IM'ing I am using "gaim", and at one time there was a TIK version
supported by AOL. gaim works fairly well.... have to do a search for
it. Don't remember where I found it, off the top of my head.

Subject: PPP Connect but can't ping.
Date: Tue, 07 Sep 1999 10:42:07 -0700
Hello y'all,
I've sampled the wisdom of the newsgroups for some time now, and
I'm still a bit stumped by the problem I'm having with my ppp
connection.
Right now I'm using linuxconf to setup and run the connection. The
connection
has a static IP address. On the ``other side'' is a Sparc 5 running
ppp-2.3.5. On my side is RH6.0 with ppp-2.3.8. Below you will find the
log file after the chat connection is established. There does not
appear
to be any problem with the modem, since I can make a direct modem
connection
using e.g. minicom. Furthermore, the ppp connection works just fine
under
Win95. Finally, this same connection worked just fine under RH5.0.
As you will see from the log file, it appears that the connection is
established successfully and that LCP and IPCP negotiations are carried
out
with the peer. However, when I try to ping the peer, even by IP number,
nothing happens. The packets are sent but never received. This
probably
has to do with the frame errors that ifconfig reports (see below).
Then, if
I wait long enough, the connection will LCP time out due to the failure
of
the peer to return echo requests.

I have a cable modem with a Slackware 4.0 (2.2.6 kernel) box set up
with ipchains. There's a network of three additional machines behind
it (1 Linux and 2 windoze).
Recently, I started seeing the following in the packet log:
Sep 6 10:35:04 grumpy kernel: Packet log: input DENY eth0 PROTO=1
192.168.0.1:10 224.0.0.2:0 L=28 S=0x00 I=256 F=0x0000 T=64

Sep 6 10:35:10 grumpy kernel: Packet log: input DENY eth0 PROTO=1
192.168.0.1:10 224.0.0.2:0 L=28 S=0x00 I=7680 F=0x0000 T=64
I'm assuming that they'll get dropped and I won't have to worry <g>.
Besides, what would they take from my home machine???
However, over the weekend, I noticed the following OUTPUT packets in
the log:
Sep 6 10:37:31 grumpy kernel: Packet log: output REJECT eth0 PROTO=1
10.100.100.1:8 192.168.0.1:0 L=84 S=0x00 I=5682 F=0x0000 T=63
Sep 6 10:37:32 grumpy kernel: Packet log: output REJECT eth0 PROTO=1
10.100.100.1:8 192.168.0.1:0 L=84 S=0x00 I=5683 F=0x0000 T=63
Sep 6 10:37:33 grumpy kernel: Packet log: output REJECT eth0 PROTO=1
10.100.100.1:8 192.168.0.1:0 L=84 S=0x00 I=5684 F=0x0000 T=63
While these were dropped, do they mean that it's too late?? Is the
system compromised?? Note that the 10.100.100.1 address is one of the
internal machines on my network (modified to protect the innocent)
Two questions:
1. How can I determine if there's a problem with the firewall system
itself?
2. Where can I find a reference for the "L=", "S=", etc. outputs from
the logger.
TIA . . . .

Had a similar problem with my GE25000III PCI Ethernet card. What I had do was
not to use the NE2000PCI driver but, the non-PCI driver. Used the DOS program
to find by IRQ and port data. Went back to Linux and use one the KDE tools, I

Subject: Modem configuration for a PPP connection in a leased line

I have two USR Sportster 28800 external modems, one in each end of a leased
line, and I wanted to configure both modems as host and guest.
So I created a options.ttyS1 configuration file in /etc/ppp diretory to work
with pppd. I specified the connect option to use a chat script but, the AT
command I put there is not connecting the modems.
I also set up a line in the inittab file to respawn my pppd script for the
device (/dev/ttyS1).
I looked up in the Leased line mini HowTo but it couldn't help.
Can anybody give any help on those AT commands or on the modem DIP switches
configuration (if it is the case...)?
