Subject: I am confused about Sendmail.
Date: Wed, 20 Dec 2000 21:30:00 -0500
I have the sendmail Bat Book and the DNS and Bind Cricket Book, but
cannot figure out how to handle what I need. I normally generate the
sendmail.cf file by editing the sendmail.mc file and running m4 on it.
I have two machines networked together (named valinux and touchl) on a
tiny (2-machine) network, and I configured each one so that sendmail can
send my stuff to my ISP and out over the Internet. One of the things I
had to do to make that work with my ISP is set my /etc/sendmail.cf file
to say (in part):
# my official domain name
# ... define this only if sendmail cannot automatically determine your
domain
Djjdbeyer.exit109.com
(jdbeyer.exit109.com is my static IP address's name)
so when my ISP (mail.exit109.com) examines my domain name, it is valid
and it is willing to forward the e-mail.
If I set up both machines like this, I cannot e-mail from one to the
other (even though ping, etc., work between them) because the sendmail
at the target machine (touchl, in this case, but the problem is
symmetric) complains:
553: touchl.localdomain config error Mail loops back to me (MX problem?)
554: [EMAIL PROTECTED] ... Local Configuration error
I could be wrong, but I doubt it is an MX problem, because my only named
(bind) file that discusses MX records on the valinux machine says:
@ IN SOA valinux.localdomain. jdbeyer.exit109.com.
( 2000062100 10800 3600 604800 86400 )
IN NS valinux.localdomain.
localhost IN A 127.0.0.1
touchw IN A 192.168.1.1
valinux IN A 192.168.1.250
valinux IN MX 10 valinux.localdomain.
touchl IN A 192.168.1.201
touchl IN MX 10 touchl.localdomain.
Now if I change /etc/sendmail.cf on touchl machine to read (again, in
part):
# my official domain name
# ... define this only if sendmail cannot automatically determine your
domain
#Dj$w.Foo.COM
I can send e-mail between the machines just fine (in either direction).
But then I cannot send e-mail from touchl through my ISP because it then
uses domain name localhost.localdomain, and my ISP does not like that.
On valinux, my /etc/sendmail.cw file is:
# sendmail.cw - include all aliases for your machine here.
valinux
valinux.localdomain
jdbeyer.exit109.com
localhost
localhost.localdomain
On touchl, my /etc/sendmail.cw file is:
# sendmail.cw - include all aliases for your machine here.
touchl
touchl.localdomain
localhost
localhost.localdomain
I seem to be stuck in a rut here. Can anyone give me a pointer, into the
Bat Book perhaps, so I can configure all this wo work?

it would probably help if you posted your /etc/modules.conf, your efforts to
load the modules (scripts, whatever), the output of /sbin/lsmod - and what
sound card you happen to have.
off the top of my head... it's better to use modprobe to load things...
since alsa has a lot of dependencies between the different modules.
also... did you run the 'snddevices' script when you ran through the alsa
install?

Or is there something else in the squid conf file?

Hi guys:
I have recently come across two old 386 laptops with low density disk
drives. I have used some of the small linux distros but they all come
on one high density disk. Is there anyway to make one of these small
distros fit and boot off a 720K low density disk? Or better yet, is
it possible to do up a small kernel with basic linux utilities to fit in
720K or less...
If this is possible, how would some of you do it. For instance, I can
put a kernel on a disk, but what utilities should I include with it???
Thanks...
Sincerely,

If you want to run MS VB on Linux you are out of luck AFAIK. However, you
can host your data on MySQL and access it from Windows using MyODBC. I assume
this was your real question.
A link to MyODBC is available at http://www.mysql.com.

Yes, but AFAIK some standard programs will "break" at the new speed unless
they're recompiled too.

If you are going to run this a long time and you are using a standard
distribution turn off as many processes as possible. In particular turn
off crond. It seemed to want to do some sort of scan at midnight on my
machine, and there was little else you could when it was running. It
really sucks when you are trying to log in under a console and it reads in
text like molasses.

Hi,
I'm also trying to have my hardware clock use the net for updates but I'm a new bee and
therefore limited - for now.
I tried the two command mentioned in this thread (rdate & ntpdate) from a Konsole but
neither
command was found. I'm running 7.1 so maybe that makes a difference.
Any suggests? I'd like to just get it to run from a command line first then move up to
a cron
job later. Oh ya, I'm on cable so I don't run PPP.
Thanks in advance the help
Regards,
Bob

I use xntp3 on my system (and I use cable modem like you) and it is
much more automated and easy to setup. Anyway, install the appropriate
package for this program (eg. xntp3 RPM under Red Hat) and edit the
configuration file /etc/ntp.conf with something like this:
driftfile /etc/drift
server <time server 1 ip>
server <time server 2 ip>
server <time server 3 ip>
authenticate no
No start up the time server using whatever is in your bootup script
(eg. in Red Hat you do /etc/rc.d/init.d/xntpd restart) and wait a few
minutes till it synchronized and then type 'ntptrace' and it will
estimate how close it is tracking to the other clock. If you run this
before it synchronizes, it will give some kind of error. This program
is quite sophisticated in that it will allow backup time servers and
will even store drift values in a file so if you lose the connection
to the net, it will keep on correcting based on this old drift values!
So that means after you get it all working, leave the computer on for
a couple hours so it get a good estimate of the drift value for future
use.
