I just replaced my zoom 33.6 with a 56k usr/3com v.90
The zoom had a W2 in its init script in order to display the connect
speed in /var/log/messages.
The usr does not use W2, does anyone know how to display the connect
speed with this modem.
It is a model 0484.

That really means that you need to get an up-to-date "netkit" package
from one of the distribution archive.
Or it could mean that your old init system scripts have to be
corrected if they are explicitly adding interface routes. Under the new
kernels (2.2.x) the "ifconfig lo up *" command that is executed
somewhere in the network initialization subsystem *should* automatically
add the necessary "interface routes" to the kernel routing tables, and
the script should *not* attempt to do it again.
The "Documentation/Changes" file is not for the casual Linux user, it
is terse, full of kernel hacker jargon, and sometimes just to vague to
be really useful. Even if it seems clear, you sometimes need to go read
the kernel sources and struggle thru the poorly commented code to figure
out what *really* happens.
I dearly like Linux (almost to the point of love) but the kernel code
just *needs* more comments. I don't care that the kernel tarballs get
bigger, the comments add more value to the kernel than any "kewl" new
feature can.

I have a feeling that this might be the problem, though I am not sufficiently
familiar with Linux configuration to be sure. Here's something I tried after
having run vncserver on the Linux box and vncviewer on the WIndows box, On
the Linux box, I tried:
xman -display PC007248Linux:2
expecting to see xman appear on the windows PC. However, the Linux CLI
came back with...
_X11transSocketINETConnect: Can't connect: errno = 101
Error: Can't open display@ PC007248Linux:2
On the windows end, running vncviewer with the -console option displays
a console window that confirms the display name...
...
VNC authentication suceeded
Desktop name "sjm's X desktop (PC007248Linux:2)"
Does this support the notion that I might need some new entry in the
routing table? If so, how do I do this? Where is the routing information
held? Is it the IP address of the Linux box I need to add here (i.e.
the *server* end IP address)???
I feel I'm closing in on fixing this thing.
Thanks for your help so far.
Steve.

Hi All,
I am wondering if anyone can give me some pointer regarding
the "jiffies" variables defined in the shaper.c module.
The module is located in: linux/drivers/net/shaper.c
I have a tough time to locate the value of this "jiffies"
variables. Also, if someone can shed some more lights on the
algorithm of the module "shaper.c", I would appreciate very
much. Thanks for your time and helps.

Subject: Bootable Network cards... ?
Date: Fri, 12 Mar 1999 10:16:26 GMT
Using Debian on 486s...
I want to boot a 'Node' machine from a 'Host' machine. Setup is 10BaseT
Ethernet connected via a Hub. If I have no HD in the 'Node' do I require
a Bootable Ethernet card? Or is there a special setup I can use that
would have the machine boot from the 'Host' with a standard Ethernet card?
I guess it would be a diskless workstation sorta, my final goal being a
Cluster setup with multiple 'Node's.
Any info appreciated, please Email reply in addition to posting.

Hello,

Dang! I just discovered, that don't even have Netscape installed under
Windows on _my_ machine. I am reading my mail with Pegasus there.
However, that is inconvenient for me too, so I will have to look for
a nice solution to read mail in whatever OS and have the same
mailfolders.
I fear, that linking the directories won't help. After all, the
read/write
request is directed to the other disk and will have the same problems
there.
I just checked: the dos-disk is mounted as root and all the files are in
the group root with the permissions 764. Readable for everybody, so they
should at least show up, don't they?

I guess the problem is, that vfat does not understand permissions.
AFAIK, the vfat partition is mounted with root-permissions at boot-time
resulting all files to me owned by root.

How do you mount your dos-partition? Could you show me the line of
your /etc/fstab please?

That's not the point, I have to use Windows sometimes (using Framemaker
for my job, when I work at home sometimes) and I would like to check my
mails without booting another OS. This friend of mine had this problem
at first, but after all I discover, that I am working with two
mailbases.
Yuck.
> I'm using Agent for Windows in Linux and I use the same copy.
You are using it through Wine? Or is it available for Windows and Linux?
I don't want to install Wine on this machine, my time is limited and I
don't want to have _another_ Program to fiddle with.. ;)

I have two Tokenring LAN's connected by a FDDI ringswitch. Both LAN's
are on
the same network : 10.10.0.0 subnetmask 255.255.0.0. I can ping from a

ping to a host on LAN 1 and not to a host on LAN 2. I am using the

Subject: Packet Filtering with dynamic IP�s
I have my LAN connected to the Internet over a Linux-Gateway using ISDN
(ippp0). Everything works fine with masquerading. Now I want to set up
packetfiltering when the link goes up.
I inserted following lines in the dial-up script, where $INTERFACE means
ippp0:
# flush and deny everything
ipfwadm -O -f
ipfwadm -I -f
ipfwadm -O -p deny
ipfwadm -I -p deny
# my LAN needs full accces to the gateway
ipfwadm -O -a accept -b -S 0.0.0.0/0 -D -W eth0
ipfwadm -I -a accept -b -D 0.0.0.0/0 -S 192.168.42.0/24 -W eth0

kernel: ip_rewrite_addrs(): shifting saddr from 192.168.0.99 to

Your local IP (dynamically set) is now 212.7.130.45, so above Inputrule is
useless. Use Local-IP
You might have a look at my Firewall rules for dynamic IP's at
http://www.toetsch.at/de/tips/linux/99/08.htm
There are also rules against spoofing.
You can download the rules as TXT from the 2. page.
(Also would be nice if some firewalling profis have a look at the rules)

No you've to masquerade your local net:
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0 -W $EXT_INTERFACE

Well, I don't have all the answers, as I've not tried this yet, but
I do have a simple question on a hardware level.
I'm assuming that you have the machines attached via twisted pair
cabling and a hub. Can the hub deal with Appletalk? Appletalk is not 802.3
compliant, and many hubs can't deal with anything that isn't. It might be
803.2. I get the numbers mixed up at times, and it's too late for me to dig
up my hubs' manual. :-) Eitherway, Appletalk frames are not complient, and if
the hub can't handle it, it's not going to work.
