To find out what IRQ's are in use 'cat /proc/interrupts'. Similary
'cat /proc/ioports' to determine I/O locations in use. If your cards
current settings are in use, you can use the information to pick new
unused ones. This may indeed be your problem and all else may fall
into place once you check it out.
Here's some additional info on what I did; You might find it useful as
a short summation.
You may also need to edit a couple of other files. One is
/etc/modutils/aliases to insert the driver. Examine the file with the
Ethernet HOWTO nearby and it will be clear what to do. Here's the
relevant lines from mine:
#alias for your ethernet card(s)
alias eth0 3c59x options=3
alias eth1 tulip
I have two cards so I load the drivers for both and alias them to eth0
and eth1 respectively. As you can see, you can add options if
needed. Reference the Ethernet-Howto as well as documentation for your
card's driver in the kernel source under Documentation/net/ .
You will also probably need to edit /etc/modules to have your driver
loaded at startup. make a copy of the original 'cp /etc/modules
/etc/modules.orig' before editing. Here's my edited /etc/modules:
# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a `#', and everything on the line after them are ignored.
# An entry named `auto' will cause the system to start kerneld immediately.
# Kerneld then loads modules on demand. `noauto' disables kerneld completely.
lp
serial
ppp
# added by omega 1/5/1999
3c59x
tulip
Last, but not least, you need to set up the interface (ifconfig) and
the routing. The NET3-HOWTO is the source of info on this. Make a
backup of your original /etc/init.d/network as we did above for
/etc/modules and then edit appropriately. Here's mine as a sample:
#!/bin/sh
#establish the networks and routing
ifconfig lo 127.0.0.1
route add -net 127.0.0.0
#added 1/9/1999
#for 3c590 internal lan hookup
ifconfig eth0 192.168.1.3 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
#added 1/9/99
#for SMC EtherPower PCI (eventual cable modem connection)
#to be changed at a later date
ifconfig eth1 192.168.2.1 netmask 255.255.255.0.up
route add -net 192.168.2.0 netmask 255.255.255.0 eth1
#eventually all routes through cable rather than diald slip setup
#route add default gw 192.168.2.1 eth1

Subject: Probably BUG: Re: Samba: request_oplock_break: no response (again and
Ok, some time ago I search all Samba listproc archives and found
the same problem. I posted a message to the samba-bugs, and here too,
but got no responce(s). Some people tell that this is a Windows problem,
not a Samba, but I disagree -- _all_ our clients have same problem!
I posted a detailed log file too (log level 10). No responce!
This problem seems to be exist in all 2.0 line (starting from alpha-...,
do not remember). In detailed log there is a message indicating that
smbd got a responce with len = -1 ! (I can't look to this log now,
since I'm at home now, and have no samba here...)
As I see, there are (some) users in the 'net that have this problem.
And so this is probably a bug in _samba_, not clients, or _common_ bug
in clients and if so, it should have a workaround in samba code...
As you wrote, 1.x line have no this problem at all, but it correctly
implements oplocks.
P.S. Another thing around this problem: at monday I will try to compile
2.0 code by gcc, not by (experimental) pgcc with all optimization,
may be this help...

Subject: Connect without hub
Date: 17 Jan 1999 08:18:35 GMT
I am planning to connect the following two machines with ethernet
without using a hub.
(1) PC (Pentium II 266 Mhz; Intel AL440LX mother board) with
multiple-boot set up for Win95/Linux/FreeBSD
Ethernet card: 10/100 Mb (will be Intel EtherExpress Pro or 3Com)
(2) Sun Sparc Classic with Solaris 2.5.1
Ethernet adapter: 10 Mb (preinstalled in the system)
These machines are only two feet apart.
I heard it is possible to directly connect two machines with
ethernet cards if you use a crossover 10 baseT cable.
But I would like to make sure it is really possible in my case,
since I have no experience in setting up an ethernet connection.
There is no possibility to add another platform in the future,
hence no need to use a hub.
However, I would like to know the following points:
(1) Will there be any degradation in performance or stability if
I do not use a hub?
(2) Will there be any danger in connecting 10 Mb only (Sparc) directly
to 10/100 Mb (PC) with a crossover cable?
(3) Will there be any other problems if I use a crossover cable
without a hub?
I would appreciate any help, comment, or pointer related to this subject.
Thanks in advance.

Subject: lpd configuration problem
Date: Sat, 16 Jan 1999 13:26:10 +0000
Hello,
I am running RH 5.2 on my computer and I'm having problems sending print
jobs to a remote printer. Apparently my lpd is not appending the
hostname to the configuration and data files, so the lpd on the
printserver is not processing the requests. Here is the log from the
printserve's syslog:
%Jan 5 16:24:41 printserve syslog: /usr/local/lib/lpd: ap_gradcol-
Printjob:
control file origin 'Aa02487' and H entry 'dharma.princeton.edu' do not
match
at Tue Jan 5 16:24:41 1999
The sysadmin sent his opinion on this:
"The 'H' entry is one of the entry's inside the control file, indicating
the host name that sent the file. The "control file origin" is based
on the filename for the controlfile and datafile; chances are your lpd
is not building those filenames to properly include the hostname. So
if the control file 'H' entry says "myhostname" the files might be
named 'dfAa03142myhostname' and 'cfAa03142mythostname'.
If you want to print, you'll need to reconfigure/fix your lpd."
So, HOW do I reconfigure my lpd? There is nothing in the man pages that
talks about any configuration file.
Thanks for your help.
Sai.

Subject: Problem with netscape, ppp and RHLinux
Date: Sun, 17 Jan 1999 02:23:34 -0600
I am having a strange problem with RH Linux, netscape and ppp:
I am establishing a ppp connection successfully, and am also able to start
up netscape. However, intermittently, when I use the slider bar, all the
fonts seem to get messed up: even in windows outside the netscape window. I
suspect that this might be either netscape or pppd overwriting some X buffer
somewhere, but I don't have any clear ideas. The only cure that I have
discovered this is to leave X and restart. I don't know if this a networking
problem, a netscape problem or if it could possibly be happening because I'm
using an older version of RHLinux (5.0).
Has anyone experienced anything similar? Any hints will be very much
appreciated.
Thanks in advance,
Anthony Quas

My ISP has flatly told me they will not help me configure Linux.

With SuSE thios is very easy,
edit your /etc/rc.conf
Try finding MSQ_START
Change MSQ_START="yes" instead of no
Change MSQ_NETWORKS="" in your ip address f.i. "192.168.0.1/24" the /24 is a
class C mask. (24 ones)
MSQ_DEV="" the device on wich masq needs to be used probably "ppp0"
MSQ_MODULES should be
="ip_masq_cuseeme ip_masq_ftp ip_masq_irc ip_masq_raudio ip_masq_vdolive"
NOw you probably need to stop inetd and start it again. Or just plain reboot
will always do the trick. (All this is also in the SuSE handbook)

Oops forgot one thing.
In order te get it working, you need to setup a default gateway address on your
other clients.
This default gateway address shoud point to the IP address on your Linuxbox.
NOT THE PPP ADDRESS!!! But your standard IP address on eth0

I've just tried something I thought would work, but there's something
funny going on which doesn't allow it.
I created two C programs, one (infilt) waited for a file to be created,
and then printed to stdout. Another (outfilt) waited for "Escape
character is" on stdin, and then produced that file.
I used them as so:
infilt | telnet www.iinet.net.au 80 | outfilt
My programs seemed to work fine. I set debug timers and everything, and
everything matches. "outfilt" detects the correct line, creates the
file. infilt detects that file has been created, waits for one second
(just in case) and then outputs my text. Then it exits after another 5
second wait. outfilt exits after being depleted of input. The text
sent by infilt just doesn't seem to have been received by telnet.
I've also just tried it on a normal telnet session, detecting "login:"
and sending a name, but telnet still looks like it can't receive the
login name I send it. The same programs without the redirection work
fine.
So, is there something else about telnet which I need to know ? Like it
can detect where stdin is coming from, and not allow it unless it's from
a normal login ?
Is there another program like telnet I can use which would work ? Is
there perhaps a sample program using sockets which I could modify to do
what I want ? I'm a good C programmer, but have never used sockets, or
done much TCP/IP before, so it's easier with a sample program than doing
it from scratch from man pages. Should I look at the source code for
telnet, or a web browser, or ftp or something ?
Thanks.

I'm sorry you're drawing doesn't make any sence to me, but you can add

But as it seems on your drawing eth0 and eth1 live on the same subnet,
routing to the same subnet has no use.

I appreciate your help, however I am not trying to print to a novell server...
The device attaches to the centronix port on your printer and takes a RJ-45 cable

It works rather nicely for the Windows machines that I have, but now that I have

You could compile IP accounting in your kernel this gives track on wich
ports and wich ip addresses there has been masqueraded.
But you could also install I thought it was called "ipwatch" this shows
it real time very nice.
You can browse to ftp.suse.com and check out their n1 and n2 directory
it must be in here somewhere it might not be called watch but it surely
starts with ip.

I don't know open DOS at all. But if OpenDOS has network clients for
NT / Windows 95 and it supports an IP stack yes then it is possible.

No problem at all. The 386 is a pretty fast processor for routing means.
But be sure you enable 386 optimation and optimize host has router options
in your kernel settings

Enabling WINS won't do very much.
What you should do is edit /etc/resolv.conf
and enter the ip addresses of your ISP's nameserver.
The errors that you get are those sites that aren't cached and so the ip
addresses to there names arent known. We use DNS to resove those nice names
in to cryptic IP addresses. If your client can't find such a DNS server it
can't get a IP address and that is when your browser starts to moan
