Subject: Please help. Sendmail not delivering local mail on Linux
Date: Sun, 31 Jan 1999 11:18:49 -0600
Oh knowledgeable sendmail gurus, I need some help!
First the problem. All mail is received and sent properly via UUCP,
however all incomming mail gets put right back into the uucp queue to be
sent back out rather than delivered to the local user. It is as if the
mail system is confused as to its idenity.
I think my sendmail problems might have to do with the strangeness of my
internet connection/mail domains. Let me just review it for you.
All email sent is eventually aliased to the andante.mn.org domain. This
domain is my internal domain on all my machines as well as the domain on
most of my mail. A local ISP provider Skypoint also hosts my visible
commercial domain andnate-systems.com. Mail sent to andante-systems.com
is aliased to andante.mn.org for all it's pseudo-users. For example
[EMAIL PROTECTED] and [EMAIL PROTECTED] are sent to
[EMAIL PROTECTED], [EMAIL PROTECTED] is sent to
[EMAIL PROTECTED], etc for all the pseudo-users in
andante-systems.com. I then pick up the andante.mn.org mail via UUCP.
I have a second provider for my ISDN internet connection. Gofast.net is
my ISDN provider. My internet connection is a Pipeline Router hooked to
the ISDN wall plug on one end and to my 3Com hub at the other. The
Pipeline Router acts as a router to the Gofast DNS.
My /etc/resolv.conf file looks like this:
############################
search andante.mn.org
nameserver 200.46.63.1
nameserver 209.46.63.6
The two nameservers are dns servers at Gofast.
Now Gofast does not appear to know about andante.mn.org. I can not ping
andante.mn.org. I think this might have something to do with my machine
NOT knowing its identity with respect to mail delivery. Does sendmail
as the dns if the mail is local? I have tried putting the domain in the
sendmail cf file and it makes no difference. Should all that not be
retrieved from the above resolv.conf?
Please help if you can.
If anyone wants to see my sendmail.cf I can mail it.
Thanks

Reply-To: [EMAIL PROTECTED]
Actually, dhcpd doesn't create the dhcpd.leases file, but it does
maintain it. But YOU must create the initial file (with nothing in
it.) Just make a blank file and call it dhcpd.leases. DHCPd will
start maintaining the leases in that file. You CAN edit that file
manually later on to do things like remove leases, free up leases but
be very careful you keep all the braces intact. DHCPd does periodic
maintenacne of thfile to keep it cleaned so you shouldn't have to
touch it.
Another pitfall I found... A backup of DHCPd.leases is made called
~dhcpd.leases. I would suggest a cron entry to back THIS file up or
rename it. If you use emacs for editing, you know that emacs creates
backups preceded by a tilde. This could really mess you up to find
your system backup of the leases file got overwritten by emacs
backup...

You don't use an ip address to connect, their end should supply you with
an
ip address.
What sort of authentication do they use
1. Plain text login
2. PAP
3. CHAP
4. MS-CHAP
Getting this info would be a good start.

I have the same problem: I have a standalone system. I only
call my ISP with a modem. Yet Caldera OpenLinux 1.3 installation
procedure (LISA 3.0) asks me for a full domain name.
What numbers should I use without screwing up either my setup or
the Internet connection? Something like 127.0.0.1?

Create a /etc/lmhosts file on your Linux machine. It needs to know
how to resolve the name "lucifer" to an ip address. Something like
this: (assume Lucifer's ip address is 10.1.1.1
/etc/lmhosts
10.1.1.1 lucifer
That's it. Should work once you get that going.

Or use SSH. Run sshd on the Linux box and get a SSH client for NT
(commercial or free). SSH's traffic is encyrpted, so it's better than
telnet since telnet passes the username and password in clear text!

Subject: 3c905 board problems not seeing network?
Date: Sun, 31 Jan 1999 21:15:58 GMT
I have 4 workstations on the internet through a DSL modem on the @work
network [@home].
All the workstations are winbloze running 3com 3c905 NICs in 100Base-T mode.
The hub is a dual speed, so it works great with both 10 and 100 base cards.
All the workstations can see each other and see the internet. The linux
redhat 5.1 workstation can't ping anyone but itself. No one can ping it.
They are all on the same subnet, with the same gateways, etc. I've seen
others say their 3com based linux workstations exhibit the same problems,
has anyone found a solution?

Just turn ip-forwarding on in kernel (recompile with the option and then
write "echo 1 > /proc/sys/net/ipv4/ip_forward" . If you have set up the
routing table correct, then this is all you need.

Oho, message got patched somehow :(.
Well let's repeat.
I've NT 4 SP3 as PDC and Linux/Samba as a workhorse in this domain.
Everything seems to work but when I turned debug level 100 I got following
messages in a log file:

Is it critical? Where does it come from? Domain name of SambaServ was
set same as domain name of PDC. Does PDC add kind of identifier to domain
name in shadow? ("80001000")

Your linux box already has everything it needs to do routing:
ifconfig - sets up the interfaces
route - sets up the routes
Step by step:
1) install two NIC's into the Linux box
2) get your kernel to recognize them
3) make sure that your startup script has two ifconfig calls:
ifconfig eth0 <ipaddr0> netmask <netmask0> broadcast <broadcast0>
ifconfig eth1 <ipaddr1> netmask <netmask1> broadcast <broadcast1>
under debian this is done in /etc/init.d/network
4) make sure that your startup script has the following route calls:
route add default gateway <gateway_ipaddr>
BTW, you don't need route commands for the networks directly connected to
the linux box. It can figure those out from the ifconfig commands.

RFC 1918 describes which IP numbers should be used for "private"
networks. For small networks, the class C reserved numbers should suffice
as listed above (except there are two errors):
127.0.0.1 localhost
192.168.1.1 host-a
192.168.1.2 host-b
192.168.1.3 host-c
All the hosts should be on the same class C subnet, 192.168.1.0, which
has the netmask 255.255.255.0.
If you need to have a domain name, pick something that CAN'T exist, like
mynet.local. ("local" is not a top level domain) So then you have:
127.0.0.1 localhost
192.168.1.1 host-a.mynet.local host-a
192.168.1.2 host-b.mynet.local host-b
192.168.1.3 host-c.mynet.local host-c
Hope this helps,

You would need two interfaces in the Linux box, one to the outside
world, one to the internal network. You could connect the internal
network via a small hub and UTP cabling, or via coaxial cables
using BNC (bayonet) connectors on the NIC or a mixture of both.
You would set up the Linux box as a proxy Firewall, using the
single IP address from your ISP. Read the HOW_TO. I suggest that
the internal addresses you use shoudl be from a private range.
