It's likely that this can be got round also, by (for example)
gaining knowledge of the MAC address used (using a network
sniffer) , then unplugging the controller and issuing
RARP/BOOTP/DHCP requests (which?  Hey!  You've just plugged a
sniffer into the network!) to convice the server that the box has
just booted and should be allowed to NFS/whatever mount the
remote filesystems.

I could be wrong, however, but I'd need some convincing.

If the hacker can do this, you've lost, as they could remove the
harddrive and mount on their laptop, edit /etc/passwd & friends,
replace the drive and go on their merry way.

Actually, you could boot using initrd or similar, and when you
mount / require the passphrase for the encrypted filesystem.

But this destroys the possibility of unattended reboots, and
people may well be able to obtain the passphrase by compromising
the keyboard controller or cable.

If people have access to the hardware you must assume that they
have root/adminstrator/whatever on that machine, and gaining such
privilages on a local machine should not be able to compromise
the rest of the network.

Hello, 
     I am trying to use a couple of mongrel 10 meg ethernet cards.  The Mac
address starts with 00:c0:a8:34.  This points to a GVC corporation.  Checking
their web page shows only a realtek 8029 type card.  I need to use 2 cards in a
new PC so I need to turn off PnP and set the card manually for irq and

Any Ideas or help ?

Hi,

I want to create a PPP connection ... I've tried with minicom and
ppp-on/ppp-on-dialer scripts. No problem with the modem, I can dial the
Box with which I want to establich my PPP connexion, but if I type the
command "ifconfig", there is no ppp0 anymore !

I've read HOW-TO's and FAQ, and it seems to be obvious to have this
interface after PPP connexion ....

I don't know what I have forgotten ....

I am using Telnet to link to a RH5.2 server. The PgDn and PgUp keys
don't seem to work properly, especially when used with more, less or

Reply-To: [EMAIL PROTECTED]

i need to figure out a way to have my linux router keep track of bytes 
sent/received to three separate networks (all connected to the internet via the 
router). currently i've got ipfwadm doing it, but unfortunately it doesnt quite 
offer the versatility i need.
basically i need something that can monitor how much traffic goes in and out of 
each separate network. it would also be highly preferable if we could keep 
track of what addresses on the internet they are accessing.

Date: Tue, 18 May 1999 22:37:28 +0200

Hi all,

i ad set up a diskles X-erminal th SuSE5.1 which had kernel 2.0.32 and
work fine. Now I want to upgrade to SuSE6.1 both the server and the
client. All runs fine so far except the client doesn't boot. The reason
is that the BOIOTP request doesn't reach the dhcpd of the server. I can
see in /var/log/messages the DHCP-request of the bootprom, and the
tftp-requests of the used bootstrapper up to the point where the kernel
vmlinuz is delivered. I can see the delivered kernel boot up to the
BOOTP-request which isn't seen in /var/log/messages and times out.
I tried kernel 2.0.36 and kernel 2.2.5 with same result. The old 2.0.32
works fine.

Is this a bug in the new kernel versions or what could be the reason ?

Thanks for your help.
Thomas

Date: Tue, 18 May 1999 15:27:58 -0500

Hello-
    I am currently trying to implement a program which requires LLC-layer 
communications
with an external device.  Specifically, I need to be able to communicate using SAP 4 
protocol
over a token ring network.  The program is written in C on a Redhat 5.2 machine running
kernel 2.0.36.

What I need to know is if there is a way to do LLC-layer, SAP4 level communications 
under
linux?  If so, is this acheivable via tcp/ip sockets, or is there another C 
api/library functions that can be utilized? 
If any of you know, or can point me to resources that will allow me to find out, I 
would greatly appreciate it.

Thanks.

Hi,
        I am trying to setup a network in my home consisting of two linux
boxes and a hub. So far it looks something like this:

192.168.1.1     arson.toughguys.org     arson
192.168.1.2     tireiron.toughguys.org  tireiron

Both machines can ping each themselves but not each other (I have tried with
names and IPs).  When I run ifconfig, it lists the Bcast: 192.168.1.255. There
is no machine at this IP address. What should the Bcast be in my situation and
how is it changed? Do I need to add any gateways using the route command? Any
and all help is appreciated.

I use smbmount //(NetBIOS Name)/(Shared Folder) -c 'mount (local mount

I have not found a way to get this to work as a user, only as root. I
think that it is a permissions thing that I have not had the time to

I had this problem myself, and it turns out that my ISP was blocking
connections to port 23 on its firewall (and told me that it would only
allow connections on a case-by-case basis!)

rlogin works fine for me, though. Otherwise you could try changing the
port telnet listens to on your box and see if that gets results.

Odd, because the tulip.c file in both these kernels sport "v0.89H".
You don't think the kernel developers would hack the driver and not
change the version number, do you?  That would just add insult to
injury.  :P

Ensure that the kernel likes your ethernet card: use "dmesg" after 
startup.

Ensure that your "ifconfig" command is doing the right thing.

Ensure that your routing table is correct.

If you don't know what you're looking for, post the results of these 
commands run on both machines to this newsgroup.

ifconfig
route -n
