Alan,
It may be random flakiness, but I reliably connect to Netcom's news server
by its DNS name using Navigator 4.08 und win95, but have never connected
to that server by DNS name using Navigator 4.07 under Linux the 3 times I
have tried. I do seem to reliably connect to that server with Linux if
I use a numerical IP address directly. It doesn't feel all that random.
Mabe 4.07 vs 4.08 is a big difference here?

I don't know what distro you're using, but on my RedHat server, in the
/etc directory I have a file called services. Port 9 UDP and TCP are
listed as discard ports. I don't really know why they're sending, but I
think they're designed to be sent to /dev/null. :-)

Subject: Samba losing connection to NT server
Date: Mon, 19 Jul 1999 16:59:51 +0200
Hello everybody,
I've got a strange behaviour when acessing our NT server using samba
2.0.3 :
First, I mount 2 paths of the NT server under /server and /fax under
Suse Linux 6.1,
an everything works great.
Some time later, the /server directory appears empty and the mounted
path on the server
disappears.
The /fax directory which is mounted to the same server, but to another
path on it is still operable !!
So I had a look to /var/log/messages and found the following:
=============================================================
Jul 19 15:50:41 CLIENT810 kernel: smb_trans2_request: result=-32,
setting invalid
Jul 19 15:50:41 CLIENT810 kernel: smb_retry: caught signal
Jul 19 15:50:41 CLIENT810 last message repeated 4 times
/----CUT----/
Jul 19 16:41:18 CLIENT810 kernel: smb_trans2_request: result=-32,
setting invalid
Jul 19 16:41:19 CLIENT810 kernel: smb_retry: new pid=1330, generation=3
=============================================================
I can get it to work again with
/sbin/init.d/smb restart
for some time, but this worked with samba 1.9 without any problems.
Anyone who knows about this ?

A question:
I just setup a samba server last week which validates user lgons from 98
machines and which was working perfectly. I used Class 'C' addresses
(192.0.1.*) for the internal network of machines. I just hooked up a
cable modem to the same box and so I had to change the default gateway
so it would look at the outside world. However, now my 98 machines won't
log into the server.....can someone tell me what I need to do to get
both working together?
Thanks.....

If the printer has its own IP stack, you can print directly to it; bypassing
NT or Novell. I've done it before, but I would have to refer to me notes on
how to do it...

No, there's no way to force the ISP peer to request anything. Either
one of the two peers in a PPP link negotiation can _request_ something
directly or through a configure-nak but neither one can force the other
to accept a particular option. In the case where a proper connection
was made the peer requests PAP and pppd agrees.

Compare this with the similar lines below from the successful session.
One of the ^Ms that follow 38400 is from the CONNECT "" chat expect/send
and this is very likely what confuses the ISP into presenting a menu
rather than skipping the menu and starting PPP instead. The ^Ms are
carriage returns, one from the CONNECT "" and one from the ISP as a
spacer to begin the menu.
Note that in the messages below no ^M is seen arriving, only that two
are sent. In this instance the carriage return from CONNECT "" is
not sent until after the `~' is found that marks the start of PPP at
the ISP and after chat has yielded to pppd. It comes too late to be
picked up and logged by chat and to late to affect the ISP. So whether
you connect or not depends on whether the carriage return is sent before
or after the ISP starts PPP .
Sometimes the ISP is slow to start PPP and is confused by the carriage
return. Sometimes it is quick to start PPP and the carriage return
problem is avoided.
A solution is to not send a carriage return. You can do this by replacing
CONNECT "" with CONNECT \d\c . The new CONNECT expect/send inserts a
one-second delay and doesn't send a carriage return. The \d shouldn't
be necessary but sometimes it seems to help. The ~ '' expect/send
probably isn't necessary but it shouldn't hurt either.

The new FA310TX boards (no longer using the DEC Tulip 21140-AF, because
they don't make them anymore) use a "compatible" chip. They work with
the Tulip driver in the kernel, but Netgear distributes their own that
I have found to work a little bit better. It's on the floppy that comes
with the network cards.
But yes, they are supported. Very much so. And they out-perform my
$70 3Com NICs. Not bad considering I only paid $11/ea. for them. :)

The newer Netgear FA301TX cards have native support for linux as they're based
on the Tulip drivers, the disk has the source to compile into the kernel with
it.

FWIW, I've had 3 of 3 Kingston NICs go bad on me. This could well be a
statistical anomaly, but it's pretty suspicious. I'd recommend a Linksys
or NetGear 10/100 PCI NIC instead. Both are ~$30 at Micro Center, less by
mail order.

I've got a Linksys 5-port (+1 uplink port) hub and have no complaints.
It's JUST a hub, though, not a switch (so I can't do full duplex, etc.).
IIRC, it was about $70 or $80 at CompUSA.
I've not heard much about the quality of different hubs. Certainly there
are no Linux-specific issues with these devices.

Since you posted this to a Linux newsgroup, I'll assume that at least one
of your computers is running Linux. In that case, I'd recommend that you
install a second NIC in a Linux box, plug the DSL router into the second
NIC, and configure that box for IP masquerading (or as a router, if you
want each machine on your network to have its own IP address on the
Internet).
