Let's call your @home interface eth0 and your adsl interface eth1.
You can configure your DHCP client (dhcpcd) to listen on eth0. You can
configure dhcpcd to run a shell script when it successfully gets an IP
address (dhcpcd has a command line option for this: "-c filename").
The following environment variables (amongst others) are set and passed
to the shell script: HOSTNAME, ROUTER, IPADDR, NETMASK and BROADCAST.
So you need a shell script that will set up the routing table that you
want and set the appropriate metric values. By using metric values, you
can set up two default routes to two different gateways (one for @home
and one for adsl) but have one route be preferred over the other. This
way, most traffic will be routed over eth1 (adsl) rather than eth0
(@home). This should solve problem #2.
Of course, the solution to problem #2 routes all of your traffic and
can't be applied to individual protocols. So if somebody makes an ftp
connection to your box via eth0 (@home), will the packets leaving your
machine for his go out over eth1 (adsl)? I suspect that they might. So
you will also need to use ipfwadm to deny outgoing ftp packets on eth1
(adsl, the preferred default route). Since there is a second default
route, the packets should then go out eth0 (@home, the second default
route). This should solve problem #1.
You will probably want to deny incoming ftp traffic on eth1 (adsl) so
that people can only ftp to your machine via eth0 (@home). In fact, you
should probably use ipfwadm to secure your linux box on all the other
ports, leaving open only those services that you need (ftp, http, smtp,
pop, icmp, etc.)
I haven't tried this, but I think that it'll work.
Good luck.

I highly reccomend diald (dialer daemon). It is extremely configurable and
invisible to the users. For example, you can tell the kids "No Internet after
9PM and before 7AM!" and configure diald to disable the link between those
hours. Very nice.

More than likely they are using PAP for authentication.
You make a chat script just like before, except that you leave off everything
after the "ogin:"
You have to make a /etc/ppp/pap-secrets file and set them up according to the
manpage.
See http://www.peak.org/next/ppp/ and get the latest binary installer.

Well you'll either have to provide a working email address or check back for
followups.
BTW there's really no reason to muck your email address in the BODY of the
messages. Spammers take them out of the headers and there's no evidence they
take them from the body (which would take too long anyway).

Subject: ppp-2.3.5 and kernel 2.2.0-pre6
Date: Mon, 11 Jan 1999 04:24:53 GMT
I've built 2.2.0-pre6 with ppp.2.3.5 and
can't succesfully send lcp packets (neither
requests or acknowledges). I send requests
but never see acks and I get requests which
I ack but get retries on those requests.
I've read the pppd README and README.linux,
the kernel Documentation/networking/ppp.txt,
and many others. I've done "make kernel" in
the pppd distribution and it says the kernel
sources are OK and copies nothing. I also
know that for 2.0.35 I needed to copy ppp.c
anyway because the kernel sources were newer
datestamps but older contents. Anything like
that now? The FILEVERSIONs in the kernel
sources are newer than those in pppd-2.3.5 yet
the kernel sources say 2.3.3!
The pppd-2.3.5 sources work ok with my 2.0.35
kernel.
Here's the lpc req/ack where you can see the
retries ...Jan 10 00:14:08 oscar pppd[77]: sent [LCP ConfReq id=0x1

I followed your instructions and it still tells me that I need root
privileges here is the message:
/usr/sbin/pppd: using the name option requires root privilege
I still need to be able to pass it the name option. How can I get a user
to be able to use this command? I want to use pppd as a user.

I really like wvdial also. You could also consider X-isp which goes in a
slightly different direction. I use X-isp quite a bit here now. I just
like the program and it seems quite robust.

I believe shutdown and ifconfig are in /sbin, and /sbin is not

Hello!
I'm running RedHat 5.2 and my access to the LAN does not work when
i'm connected to internet via PPP at the same time. So my LAN works when
i'm not using PPP. The problem comes from the /etc/hosts file...
Here is my /etc/hosts file that I use when my PPP works good :
127.0.0.1 localhost localhost.localdomain
As you see, there's only my localhost and in this situation, my LAN
doesn't works. But I can ping. Samba doesn't work, I freeze. I takes 5
minutes to get to ftp to my station from another station on the LAN.
To get my LAN to work, I use this /etc/hosts :
127.0.0.1 localhost localhost.localdomain
127.214.87.128 server.house.ca server (NT server)
127.214.87.129 jos.house.ca jos (win95 workstation)
127.214.87.131 john.house.ca john (win98 workstation)
(My IP is 127.214.87.130)
When I use this file, my PPP doesn't work.
Here is my resolv.conf
================
search house.ca
nameserver 127.214.1.99 (ISP domain server)
nameserver 127.214.87.128 (LAN domain server)
Ehhh... Another thing, as i've read, the file smbmount is used to mount
(map) shared volume via smb.
I installed samba 2b5 and I don't find the smbmount binary. It was not

Subject: Redhat 5.2 - Can't Get Internet Access Going
Date: Sun, 10 Jan 1999 23:53:55 -0500
We have a very simple network here - a hub feeding a few computers off of a
cable modem. No DHCP - every computer has a dedicated IP. The cable modem
(192.168.100.1) is the "default gateway".
This is exactly what I've set up in Redhat 5.2 and I can't get out on the
net. I can, however, see all the computers on our network, and can even
ping the cable modem, but can't get anywhere outside. The other machines,
all running Win98, are working fine. I've set the DNS's correctly, the
netmask is right (255.255.255.0), and the default gateway (the cable modem)
is set just as in Win98.
After many hours, I'm still getting nowhere. Obviously, I'm missing
something. It's probably something stupid. Any suggestions???
Thanks!
