You fix this by setting up some 'alias' statements in one of the init
files. It has been thoroughly discussed, once fairly recently, so hit
dejanews with the search set for one of those strings.
I did that, and it works, but I do have one other question for the real
guru's out there which is:
With our modems capable of doing their own compressions specific to
working over miles of dirty copper, are we actually doing the *real*
transfer rates any good by using these compression schemes?
Inquiring minds want to know.

Subject: NFS Client Unable to Connect
Date: Sun, 04 Jul 1999 21:26:21 GMT
I'm setting up an old P5-100 as a home server using Red Hat 5.2. I've
successfully gotten IP Masq up and running and now I'm trying to serv
part of the disk with NFS. I used linuxconf and exported the directory
sucessfully and added a user. I'm using the Netmange Chameleon client
on my Win98 box. The shared drive shows up in network neighborhood but
when I attempt to map to the drive, I get a "bad password" error. I'm
entering the correct password for the account I'm using so I'm
wondering if it's not just interpreting the code from the server
incorrectly. Is there a log file for the NFS server somewhere on the
system so I can see what is going on from the server's perspective?
I've checked the HOW-TO but the information seems very limited.
thanks,
Bill

Even the dumbest of the dumb terminals have a CPU. You have two options: use
dumb terminals connected to the Linux box - not very practical in a business
environment for a number of reasons; use personal computers configured as
low-end workstations (minimum hard disk capacity, no diskette drive, network
card, sufficient RAM based on your particular requirements) - much better
solution for a business environment. You don't even need to install more than
the equivalent of PocketLinux on each workstation either on hard disk or floppy
depending upon your workstation configuration.
Good luck!

As far as I can remember this is more do to with DNS lookups of MX
records.
Take a look in syslog, and also run sendmail -v so it can show you what
it is doing.
eg.
sendmail -v [EMAIL PROTECTED]
Sendmail is probably configured to use DNS and you may to rewrite the mc
file use hosts only if you do not use a DNS. If you do you DNS make sure
the MX records are set up correctly. ie use nslookup.
set the type=MX to only show Mail Exhanger records.
If you are not using DNS or you do not have a direct connection to the
net, you will probably want to use a SMARTHOST. ie a mail gateway within
your firewall that does have access to the outside world. You simply
forward all mail that is outside of your domain to that host.
Hope that helps.
Here's an example from my machine, I've commented out some of the names
and ip addresses...
[root@ravenwood /root]# nslookup

Date: 04 Jul 1999 22:32:37 GMT
I am a casual Linux user and I have hit a roadblock, so now I turn to those of
you who know way more than I do.
I am running Red Hat Linux Version 4.2 on a dual-boot with Dos 6.2/ Win 3.1. I
am in the process of setting up a 10/100 LAN between my P200 w/ Win95b, my
"soon to be built when I cough up the dough" PII 333 w/Win 95b and my Linux
system (a lowly Cyrix 166). I would like to use the large HDD on the Linux
machine as a storage space and backup area for the two "crash"dows 95 machines.
What steps am I going to need to take to get the Linux machine ready? What if
anything needs to be done with the Win 95b (besides reformatting the HDD and
putting Linux on) machines?
It is possible in the future that the Linux machine will also become my
Internet portal. What needs to be done in that case?
Thanks in advance
