Have you checked if the IP addresses and the names of all the desktops
are listed in the /etc/hosts file? It's really a networking issue at
hand here.
The mail server is trying to resolve the hosts' name from the supplied
IP addresses (hint: so that you will have a better looking log file) and
will work faster if these IP's are readily reverse-resolvable.
Cheers.

Run regedit and go to:
HKey_Local_Machine\System\CurrentControlSet\Services\Rdr\Parameters
add a DWORD value named EnablePlainTextPassword and set it to 1.
The reason is NT disables plaintext password authentication by
default. If security is not an issue, the above would work just fine.
Otherwise, you should use another security mechanism in Samba, such as
user or better, domain.

On what address is the card?
The driver probes a couple of addresses, as defined in
/usr/src/linux/drivers/net/eepro.c.
It probably looks like this:
/* First, a few definitions that the brave might change. */
/* A zero-terminated list of I/O addresses to be probed. */
static unsigned int eepro_portlist[] =
{ 0x300, 0x210, 0x240, 0x280, 0x2C0, 0x200, 0x320, 0x340, 0x360, 0};
Make sure your card is on one of these addresses. Also, it is a good idea to don't have
any other cards on any of these addresses.
A last thought: if the card is PnP, disable it.

It also works to do

this assumes you are logged in on the client as the user you want to log on

Linux does not have anything to do with your P-75 or MP. Linux's
responsibility stops at the Ethernet port. It generates True &
Proper TCP/IP and the Pipe accepts it.
Consult the various Pipeline-help sites for details on how to get
it going with two channels.

Check the readme, there is a section on the routing of the 255.255.255.255
route (would tell you but not by my server). Also ensure that your attaching
the
dhcpcd daemon to the correct card (dhcpcd ethx) and that all of the options
in the dhcpcd.conf are correct. I have the lastest version from www.isc.org
on a 2.0.36 machine with win98 and redhat clients running dhcpcd on the local
and dhclient on the cable modem side. Been working fine for 4+ months.

Date: Sun, 02 May 1999 01:37:18 -0700
Bob,
OK, I think I can help. Lets go.
I take it that you have configured the smb.conf file in the /etc directory.
This is the file that configures samba on how to comunicate. But you have to make
some changes to this file since you win95 machines cannot see it. Make a
workgroup name and input it into your win95 machine and also into your smb.conf
file under the workgroup parameter. In the smb.conf file you have to change the
security level to share instead of user or server. On the hosts to allow section
of the file add your win95 computers name or ip address. Make sure that the guest
account line is uncommented and add the user pcguest to your userdatabase in
linux. Don't screw around with any of the OS level or password settings and leave
them commented. Generally if you don't know what it is for, don't use it. Go to
the section in the smb.conf file where you list the shares and add the lines guest
ok = yes and public = ok to the shares. Your main problem is probably the
security level which I described above. Now that you edited the smb.conf file,
save it and restart samba with the commands /etc/rc.d/init.d/smb restart . If you
want to restart you whole networking in linux use /etc/rc.d/init.d/network restart
. Give windows a couple of minutes so it can see your linux box on the network.
If it still does not see it then restart your win95 machine. For further
information on samba see the man pages with man smb.conf . As for you connecting
to your win95 machnines from linux use smbclient -L
\\\\yourwin95name\\shareddirectory -U usernametoconnectas . Let me know if it
still does not work. Hope I helped.

Hi, I setup a firewall by ipfw from Redhat 5.2(kernel 2.0.36) and a
webserver in DMZ. I could use a web browser to read my webpage very fast
from private network or router side. However, I couldn't ping and
traceroute to webserver ip address whatever from private network or from
router side. What is the difference?
And, is it necessary to add a default route on router pointing to
firewall to make the world access my webserver in DMZ, because I need to
add a default route to my pc pointing to firewall.
High appreciated on your information.

Now I'm curious. Can you speculate on what will happen if you have a
file with more than 4:1 compression that comes through a ppp circuit
with hardware compression on both sides? Say a file that consists many
bytes, each one identical to every other one in the file? An extreme
case granted, but you get the idea. Offhand it seems like it might
cause serious trouble.
Hardware exchanging bytes at a 53 kilobaud rate might easily exceed the
115200 top speed of the common PC 16550A UART and would likely cause
PPP fcs errors with files that have long sequences of duplicate bytes.
I'd believe - until show otherwise - that this also might account for
some of the problems with files hanging during download that are seen
posted here and on comp.protocol.ppp . The 4x rule seems to imply that
you need at least a 230400 kbaud UART for 53 kbaud connections and that
even a 38.6 kbaud modem might at times get some benefit from such a UART.
Comments welcome.

Subject: 3c509 Cant see packets
Date: Sun, 2 May 1999 19:08:31 -0500
Hello all,
Well, after 9 or 10 tries I finally managed to get COL 2.2 installed on my
machine. Everything is working normally it appears except for the networking
portion.
Here's what I have.
Celeron 300A
Riva TNT
128mb RAM
3COM Ehtelink III 3c509TP
1 gb Linux partition
running dmesg show that the 3C509 is correctly detected with no error's. All
of the resources detected by the kernel appear to be correct for the card
(i/o, irq, etc..). Running lsmod shows that the 3C509 Module is loaded
(however, the Status column for the 3C509 module entry is blank, is this
normal?). All of the networking information as far as IP address, Default
gateway, etc, etc ...has been checked and double checked and is correct (the
card is setup identically in my Win98 partition and is functioning normally
here). I just don't seem to be getting any network action at all. A ping to
other machines on the network (another win98 box, and to my ISDN router)
result in nothing. I let the ping command sit for 5 minutes and it just sits
there, it never comes back with a no response message or anything, it just
just sits there saying:
Pinging <ip_address> with 56 bytes of Data:
and nothing else ever happens. The strange thing is that when I issue the
ping command, I can see activity on the hub start up between my linux box
and whatever else I happen to be pinging on the lan. This is a small network
(3 devices) so I know there is nothing else going on. This makes me think
that the NIC itself is funtioning. It just seems that the boxes aren't
talking for some reason. I've tried pinging from another box TO the linux
machine (win98 box to Linux box) and the ping times out even though the
activity lights on the hub between the two boxes begin blinking.
It looks like the 3c509 is sending butnot receiving. I can check the
netstats on the box I'm trying to ping and see that packets have come in and
responses have gone out....but the linux machine never gets them.
Again, this thing works fine under win98 so I don't think its a
hardware/wiring issue
I'm new to linux but fairly familiar with TCP/IP based networking. Is there
something in linux that I need to configure for TCP/IP or something?
Any help would be greatly appreciated.
