Really not such a good idea though. There is nothing wrong with logging

I would imagine so.
To test it, log into the console of your box, then telnet to localhost
and see if top works.

HI,
What can I do in order that any user can use pppd?.
I have done the following:
in /usr/sbin
chmod -v 755 pppd
but it does not work.
Thanks

This is commonly done and fairly easy. Many ethernet cards are detected in
multitude automatically during the kernel bootup probing (or later if you
use loadable modules). I put 4 Netgear FA-310TX cards in one machine and
it simply found them all.
Getting them to work involves getting the appropriate "ifconfig" command
performed on each one. How this is done differs by which Linux distribution
you used. In Slackware I typically just edited /etc/rc.d/rc.inet1 and
added the commands. In Red Hat, you can configure multiple cards using
the linuxconf tool or just copy /etc/sysconfig/network-scripts/ifcfg-eth0
into names like /etc/sysconfig/network-scripts/ifcfg-eth1 and so on, with
appropriate changes edited into the files. If you want multiple addresses
on each card (max of 256 aliases) you can also do this in Red Hat by making
files like /etc/sysconfig/network-scripts/ifcfg-eth0:0 and filling those
in as appropriate. I've got a dozen or so addresses on one machine done
this way (I manually edit my files).

I have not programmed in this area, but if the procedure call approach can
do what you want, you might look into RPC. Personally I take the more
direct approach and just send things as streams of bytes over sockets.

Depends. If they oute all the traffic you want to route further, then you
can just drop the box into the net and use static routes, and everything
will work fine. If you have to announc the other routers additional routes,
then you will have to run a routing daemon (you better get permission to do
this first).

as i said above, this does depend on the existing routes. A lot of companies
do only static routing, then you wont need a routing daemon.

So you better be carefull. You should take a look at the Linux Router
Project, will help you with pre-intalled router-distribution on single
disks.

Tim,
Ping -r is only to ping a local host on your attached network.
Not
to go outside past your ppp box - only inside hosts. It seems
like
your trying to ping -r the wong boxes. Can you ping boston.com
from any
machine? You should not be able to ping -r boston.com. It
should return
host unreachable. Am I mis-understanding things?

Subject: Botting diskless SPARCstation off redhat5.2 unsuccessfull...please help
Date: Thu, 21 Jan 1999 14:44:29 +1100
PROBLEM:
A diskless SPARCstation ELC will not boot of redhat 5.2.....
PRECISE DEFINITETION:
The tftp protocol works ok and sparc station downloads the bootimage of
linux bootparamd
without any problems...ARP, domainame calls etc are all successfull....
Eventually the Sparc Station mounts the directory off the linux server !
It then attempts to download a kernel file(486kb large)......
NFS READ TIMEOUT ERROR occurs...
Upon checking out the network traffic.....It seems that the linux box
sends the packets too
quickly for the poor sparc station...and the overrun
occurs.............Upon linux sending 5 packets
the sparc requests a retransmission of the entire block.
My feeling is that Linux NFS BLOCK_SIZE is by default set to 8192
bytes....BUT for some reason
upon sending that block to the client, the NFS_SERVER chops the block
size into 1024 b blocks!
.....Thus when the NFS server sends the 1024 byte blocks , it expects
each in turn to be acknowledged......It seems that the sparc diskless
client is not expecting 1024b blocks....It expects
the whole 8192 block....!!!! And thus does not reconstruct the block
correctly and requests a timeout.
HELP:
Am I on the right track?
What can I do....how can I force linux NFS to produce 8K block
sizes....?
btw...please remember that this problem is specifically related to
diskless sparc stations....
If you can help , it would be most appreciated....I am sick to death of
hacking and recompiling
the NFS code! This is a really bad problem!

Hi,
I have recently bought 2 network card 3COM - 3c509 for my 2 machine
one running Windows98 and one running Linux ver 2.0.29. I installed both
network cards in the respective machine and everything seems ok. Since I
have only 2 machine instead of buying a hub to connect the machines, I
crossed a Cat 5 UTP cable. (pin 1-3 and 2-6).
I setup the following network....
Win98 IP : 192.9.201.2
Netmask : 255.255.255.0
Linux IP :192.9.201.1
Netmask :255.255.255.0
my problem is that they can't talk to each other....but the weird thing is
when i ping from my Win98 machine, I get no response...but when I do
arp -a.....the ethernet address for Linux machine seems to corresponce to
the network card at Linux machine....
But if I do it the other way around....ie ping from linux and not getting
response, and arp -a shows ethernet address 00:00:00:00:00:00 for my Win98
network card.....
Can someone please tell me what's wrong with my config? I know the card is
alright and the cable to...(i guess)

Hi..
I'm having trouble setting up a Linux printserver in an OS/2 and
Windows environment. Linux and Samba are working fine. I can see
the entire network. Problem is, I can't see my Linux-box in the
nethood of my Win95 workstation. I would appreciate it very much
if any one of you could give me a few pointers on what I'm missing.
Here's all the (ir)relevant stuff
Domain Controller and all the servers are running OS/2. We have
some 1500 users of which 80% is on Win95. 20% is (still) running
OS/2.
Up till now all the printing was handeled by OS/2 print-servers
(not entirely reliable, to phrase it nicely) but I finally convinced
my boss to explore alternative solutions. That is where my Linux-box
comes in.
The Linux-box is running RedHat 5.2 with Samba 2.0.0 .
This is the smb.conf I made.
#======================= Global Settings =====================================
[global]
workgroup = NLHDK (the OS/2 domain I want to be in)

Date: Thu, 21 Jan 1999 22:42:18 GMT
Well,
All is good in linux land for me. All I have left (which is
apparently the source of much pain to newbies) is sound and networking.
So, here's a few questions for the more experienced:
1. Do I need to include PPP and SLIP in my kernel if I have
the one-way Mediaone cable modem whenever I get around
to a kernel recompile?
2. When I create an interface entry in the Network Configurator
in RH5.2, it never seems to activate. Why?
3. I looked into the DHCP HOWTO as it seems to be rather
important for cable modems. (Got that out of the cable modem
mini-HOWTO) The first thing one must do replace rc.inet1 in
/etc/rc.d with a new script. Problem? I don't seem to have an
rc.inet1 to replace! Does it have to do with an incomplete
networking installation?
So many questions, so little time...

No...SAMBA is just to let you see the Linux/Win9x systems like Win9x
p-p networking. I did install Samba, but before that I was able to
share a cable modem connection using wingate. However, you will need
to install an ftpd on the Win machine to get the files...so you may
find Samba (actually a small ap) is a better way to go.
