Calling uuname is not a bug, you just have a uucp router in your routers 
file. Or is it that smail allways uses that router even if you comment it out
in the routers ? I don't remeber.

The easiest way out is to install uucp, then smail will call uuname to
find out that the mail is not going to one of your uucp_neighbours and 
will try the next router. 

Even a better solution is to disable all routers and use a smart_host instead.
In that way you avoid the problems with smail not looking up MX records.

can someone explain the SNARL question in "make config"?  I am
trying to do something silimar as the originators of this thread.
I am not sure if the problem I have is a netmask issue with an
xterminal, or if I show worry about this SNARL question in the
kernel.  below I will describe the situation, and lotso output.

anybody have any ideas?

************************************************************************

I have been given a 3bit subnet (6hosts+netaddr+broadcast) from
my internet provider.  I use my linux box to establish a slip
connection and want it to provide to routing for my subnet.
the subnet is very small right now - just my linuxpc and a sun3
as an xterm to the pc (running linux-Xkernel!).

here is a little experiment I have tried:
========================================================================
ping my sun3 xterminal from a host on the slip-server side...  to
check that the forwarding and routes were correct.... this is 
so I can throw up X stuff on my sun3 from other places on the net.

host definitions:
        picard          host on net of slip-server
        distraction     my linux pc
        weenie          my sun3 as an xterminal

ip addrs:
        134.207.6.40    my subnet (using last 3 bits)
        124.207.6.47    broadcast for this subnet
        255.255.255.248 netmask for this subnet
        134.207.6.41    distraction
        134.207.6.42    weenie

facts:
        ping from picard to distraction is successful
        ping from picard to weenie fails, but packets are delivered
                to distraction's eth0

output from tcpdump while ping'ing weenie from picard:

You shouldn't need subnetting.

They should be pretting much the same..

I think only B needs it compiled..

: 4) Is B considered to be a 'gateway' to C from A (& vice versa), or is

gateway.

here is what you do...

Assign IP numbers to every *interface* (not machine)..

A.slip = 127.0.0.2
B.slip = 127.0.0.3
B.eth0 = 127.0.0.4
C.eth0 = 127.0.0.5

now on A

ifconfig sl0 127.0.0.2  pointtopoint 127.0.0.3
route add 127.0.0.3 127.0.0.2
route add default 127.0.0.3

now on B

ifconfig sl0 127.0.0.3 pointtopoint 127.0.0.2
ifconfig eth0 127.0.0.4
route add 127.0.0.2 127.0.0.3
route add 127.0.0.5 127.0.0.4

on C
ifconfig eth0 127.0.0.5
route add 127.0.0.4 127.0.0.5
route add default 127.0.0.4

That should do it.. (I think)

Don't run routed

Talk works just fine for me (Slackware 1.1.0 and kernel 1.0). Have you 
checked your message setting (type 'mesg'). If the result is 'n', you 
cannot be reached by talk. Try 'mesg y' and see what happens...

Subject: NIS domainname appearing in login banner
Date: 15 Sep 1994 10:31:26 GMT

I'm using Slackware 2.0 and I'm having an annoying problem.  The NIS
domainname of my network is not the same as the DNS domainname.  When
I set the NIS domainname, the login prompt that appears when telnet
connects contains the string 

Linux 1.0.9 (hostname.NIS_DOMAINNAME) (ttyp2)

changing domainname back the the DNS domainname makes ypbind hang
(obviously).  I'd like to have the login banner use the DNS domain so
that users don't get any more confused than they are already :-)

Can someone tell me what I should do to make this work the way that I
want it too.  I guess that a simple way would be to modify login so
that it doesn't the domainname in the banner...  Anything else that I
can try ?

getting the following error messages in a message bos that says the following

scan command returned:

This message also appears with "msgchk command returned" about every 30 seconds,
do I need to install MH first or what is going on here.

Also I located a file called Xmail.1.5.tar.Z that I cannot compile, I am getting
an error that says something like this before the compile crashes.

I know that the file it wants exsists on my drive, I just don't know how to

Does anybody know how to fix this and or set up XMH or possibly find some other

First of all, this question is not a linux problem.  This question should be
asked in comp.mail.smail.

In answer anyway, I believe the problem is not with your machine but with 
the machines that feed you (were you get your mail from).  They only know
your machine only as slip65.  This machine sees lupo and says "I never heard
of this machine".  Your machine name has to be in the hosts file of the mail
server (which you probably don't have control over).  If this doesn't answer
your question, you should post a follow-up to comp.mail.smail with more detailed
error messages (i.e. the headers of bounced mail).

Unless you are root, you can only mount the filesystems marked with the
