although not a guru methinks default is shorthand for 0.0.0.0 and mask
of 0.0.0.0, i.e. the network wildcard, it assumes a gateway. I do not
see the need for the second line as it is a directly connected network
and should find itself in the client routing table anyway, to confirm
this try
netstat -rn
Hope this helps

Did you try to look at printing HOWTO (

It contains a big database of printers supported by Linux.

Hi,
Is it possible to view Linux Xwindows on a NT box. using an equiv app
to Hummingbirds Exceed but for free. Maybe SuperX.
Linux box arch = Martox Mill G200 Video Card using SuSE.
NT box = Savage 3D Video Card.

Subject: Re: ppp problems partially resolved with zoom 2919L modem
Date: Sun, 02 May 1999 19:44:43 -0400
sadly, this issue is completely true. it's not that the modem knows what the file
is;
it's that certain patterns seem to cause the problem while others do not.
the 15 meg communicator 4.51 file downloads fine, whereas the sr1off97.exe file (8
megs or
so) does not. i've got cases where even small files cause this problem.
i am still using ppp 2.3.5, which could be part of the problem, but then again, the
problems were mostly resolved by my modem firmware upgrade.
i can also see the ppp0 device clicking off the dropped packets by using ifconfig.
the
number dropped only starts going up when the particular problem files start being
downloaded; before that, there are no dropped packets at all. if i use "kdebug 7" in
ppp,
then i also start seeing "kernel: ppp: frame with bad fcs, excess = NNNN", where NNNN
is a
seemingly random 4 digit hex number.
the problem still doesn't seem to be completely resolved. before i got the firmware
upgrade, i couldn't download sr1off97.exe at all. period. no combination of modem
init
strings or ppp options would let me. afterwards, i can download the file but there are
still dropped packets; they just don't completely hang up the download process on that
connection.
through all the original problem with this file, other connections seem fine; i can
browse
web sites, download other files, etc. but the download of the sr1off97.exe file
freezes up;
it never gets a single byte.
why doubt this such that you call me a liar? i've posted about this problem over
the last
couple of weeks because it's been driving me nuts. i've even had confirmation of the
problem on this specific file (sr1off97.exe) from one other person using redhat 5.1
(which i
was using, but the problem appears with 5.2 also) and a zoom 2919L modem; the exact
same
configuration i've got. that person (whose name i won't mention unless he doesn't
mind)
couldn't download the freaking file either.
luckily, several other people reading the PPP mailing list have tried to help me
resolve
this problem. i didn't get a single response in this group for my original posting,
but i
decided to share whatever success i had here anyway. and the only posting i get about
this
is you saying it's all bulls**t. very sad. but i don't mind. some people who are
just
learners consider themselves to know everything about everything; i don't think that
way
unless i'm very confused.

It sounds like the "host1.domain2.net" is returning
a different look-up value than 'host1.domain2.net'
when you telnet in.
Check the /var/log/secure file to see what id is
presented when you telnet in. Then do a look-up
on that IP to see if "host1.domain2.net' is
returned.

I haven't had a problem in the world with my 2849.
I note what I *think* are a lot of default settings in your init string,
and one that looks like a duplication. However, I do have the Rockwell
version while you have the Lucent chipset on yours. But I believe the
following are defaults:
&C1 &D2 &K3 V1 %C1 X4
You might check your manual to see if B0 followed immediately by B15 is
meaningful.
Keeping up with the latest modem firmware is important, as ISPs try to
keep up with the latest firmware for their modem racks. Nice thing about
the Zoom Modem Wizard is that you can back out your last update easily.
(Poor thing about it is that it requires Windoze.)

Date: Mon, 03 May 1999 02:18:02 -0400
I'm running redhat 5.2 on my laptop and my desktop system at home. I
also have an NT workstatiion. I was able to successfully network my NT
system and my desktop running redhat. I can ping between these two
systems with no problems. I'm currently trying to add my laptop running
redhat 5.2, but have been unsuccessful in getting the laptop to talk to
either the desktop running redhat or the NT box. The laptop is setup as
a dual boot system running Win98 and redhat. I'm using a 3-com
etherlink III 3c589c network card. Linux successfully recognizes the
card when inserted into the laptop. An ifconfig shows:
lo Link encap:Local Loopback

The only thing I can see that is wrong is that under Windows 98 the card
has an Interrupt of 10, and under Linux it has an interrupt of 3. Could
this be the problem? If it is, how can I change the interrupt under
Linux? The card works fine under Windows 98 and I don't see anything
wrong with the network setup. Any suggestions?
Thanks

If the 'server' is running win95 and the 'client' is running DOS you
cant use Diret Cable Conection b/c there would be no way to set it up in
DOS b/c you have to use Win95 to set the names and stuff for the
computers. If you are only using DOS you obviously coudlnt set the
configuration for that machine. If both were using Win95 then u coudl
use DCC to copy the files. IT doesnt matter that they are Linux files
b/c you were able to download them using Windows so copying them using
Win wouldnt be any different, just be like any other file to Windows.
Brandon
PS. just to clarify, do u want to copy using DCC the installation files
or install thru the DCC program? install or just copy?

Not sure how relevant this is, but I also had those same
errors in RedHat, but tried a few more /dev/tty device files
which by the way Linux is CASE sensitive, so you might
want to try that one again as /dev/ttyS2 in your ppp scripts
or if they are set up for /dev/modem, then make a symbolic
link in /dev such as:
ln -s /dev/ttyS2 /dev/modem
so that your ppp scripts find the right device name.

The modem-to-modem protocols include handshaking procedures. If you were
to run your 56K modem at a DTE speed of 19200, you should be quite safe
becaues once your modem's input buffer gets to its high-water mark, the
modem tells the other modem to suspend until further notice. (Kind of a
waste of bandwidth at 19200, though.) Similarly, if you run DTE of 115200,
connect at 53333 and manage 4x compression (213333 BPS), the modem will
sense reaching its high-water mark and throttle the other modem.
In handling real-world data, the modems reach 4:1 compression so seldom
that you'd never notice the throttling if indeed it is needed.
A nit about a comment you made earlier in the thread: the 16550A itself
is capable of more than 115200 BPS. However, it needs a different crystal
than is used in the typical PC serial-port hardware to do it. The port is
limited, but not inherently by the chip itself.

Subject: Is there a monodirectional protocol to make data/file broadcast ?
Date: Mon, 03 May 1999 10:20:56 GMT
Hi,
my question is simple, but I couldn't find an RFC or an application that made
that task: is there a protocol (RFC or other) that can be used to make file
transfer in broadcast WITHOUT RETURN CHANNEL ?
THANK YOU VERY MUCH FOR ANY HELP!

Try one of these on your linux box:
route add -host 255.255.255.255 dev eth0
If you get a message "255.255.255.255: Unknown Host"
Add this to /etc/hosts
255.255.255.255 all-ones
Then. try:
route add -host all-ones dev eth0
or
route add -net 255.255.255.0 dev eth0
Windows based clients need this route on the Linux server.

As they say at their site,
http://www.microimages.com/freestuf/mix/
MicroImages is happy to make its X Server freely
available for use on any Macintosh or Windows computers.
It installs very easily, works great, and can
pretty much be configured by referring to
the X documentation.

If you have video working on the Windows box,
the MiX server should work. It doesn't matter
what video you have on the client machine.

It just has to be sockets-compatible.

Hi there,
is there a way to have ACL on Linux ( if possible with the ext2fs )

IPX is because we do this to play games and most games don't support
TCP/IP...
