Hi,
I have a Redhat 6.0 Linux machine from which I can nfs-mount files.
However, if I stop the nfs services and try to restart it it doesn't work.
The message is shows is :
nfssvc: Address already in use
If I reboot the machine, everthing works fine ... but again if I stop the
nfs services (say if I change /etc/exports) and try to restart, it doesn't
work !
If anyone has an answer, I would greatly appreciate if you could e-mail
me.
Thanks,
Sriram

Subject: Duplex/simplex printing on HP printer
Date: Tue, 14 Sep 1999 19:18:53 -0700
Hi,
I have a Redhat 6.0 machine and a duplex capable printer attached to it
(it's a HP 4050 laserjet with a duplexor in it). I can print simplex or
duplex to the printer by going to the printer and changing the menu
entries there.
What I would like to do is to be able to print either duplex or simplex
without going to the printer (from the machine) alone. One possible way is
to probably use two printer names for the same printer and use a duplex
driver for one of it .... does anyone know where I can get such a driver ?
Or is there another possibility to do the same ?
I would really appreciate if you could answer these questions. Please cc
your mail to my e-mail address to : [EMAIL PROTECTED]
Thanks very much,
Sriram

Subject: Device Driver for FEP-4206-EP 10/100 NIC from Unicome and some other questions
Date: Wed, 15 Sep 1999 02:19:14 GMT
I have a low cost but decent NIC card (10/100 FEP-4206-EP
from Unicom). It works fine under Win98 and it also has
a driver for Red Hat 5.2 (as far as I can tell). The
driver comes as a GPL liscenced source and an object
(probably compiled with 486 in mind). My Linux is
Mandrake 6.0, compiled for Pentium. My questions are:
1. How do I compile the driver source optimized for
Pentium, so it will work nicely with the rest of my
system?
2. Regardles of how it is compiled, how do I make an RPM
out of it, so I could easyly install and upgrade it
(when needed) like the rest of the system?
3. How do I than configure the network portion of Linux
(I skipped that part in the installation time, since my
NIC was not one of the known NICs)?
4. How do I configure the Linux machine to work with the
rest of my network (peer to peer Win9x machines)
Unrelated to these questions:
5. How do I find what is the DEV associated with any of
my devices?
6. In particular, I need to know the DEV of my IDE CD.
7. How do I mount the Linux CD? What about other CDs?
8. Is there an easy way to work with Iomega ZIP drive or
do I still need to mess with kernel compilation and
configuration?
Thanks

Hi all
I am getting an intermittent error when using rexec - the host machine comes
back with Connection refused. This only seems to be when I am running
scripts which rexec many time concurrently to the host. I am using rexec to
distribute network reporting. Is there a limit on the amount of concurrent
rexec calls to a host? and if so, can I change the limit?

Here's the situation...I have a cable connection and i want to use
a linux box as a router so that the rest of the house can use the net
I think that my first problem is that the link light between the linux box
and an internal computer don't light up....I have check the cards
individually and they all work with the cable modem itself I have also
switched between a few chunks of cat-5 cable with no avail....
my second question is does anyone know where I can get a

Glad you've gotten your problem solved. There's no power
management on my system though, so it's something else.
I get *no* error messages at all.

: Yep. You can get cheap 4-port unmanaged switches for around $100.
-switches- or dual speed (dual segment) repeated hubs?
cheapest I've seen is the bay unit (something '104' as the model #) for about $165.
if there's truly a 10/100 switch for $100, I'd like to know!

A couple of things to check
recompiled kernel?
did you add the cards as modules? probably
print out of your /etc/conf.modules or /etc/modules.conf?
What happens after the modprobe, any kernel messages?
If you do a "dmesg |more" it will give you the kernel messages, see what
happens, does it successfully load?
Hope this helps

Hello....
We have a setup of PC and MAC and internet accesss is provided by the ISP
via T1. While trying to print to a color printer from Windows machine,
the printer takes a long time to print ppt. files with few mega bytes
since the data has to go to ISP and back again before reaching the
printer. Wondering if any one has setup a private network within small
business with Linux so that users can share color printers without riding
on the internet traffic through ISP.
thanks in advance.

You are using a dynamic IP and this is causing problems with the
firewalling rules in your ipforwarding, aliasing, etc. I ran into this also
until I got a fixed IP from my ISP.
There is a howto on "Dynamic IP Hacks" that you might want to look at.
There is other stuff out there too which deals in that stuff.

Hi,
I tried to setup SAMBA on my RH6.0 Linux box so that my NT 4.0
workstation can connect to it.
I have both a global and a [homes] section.
NetBIOS name = SANDIEGO
Username = helena
[homes]
Path=/home/%u
Host Allow= 192.168.1.0/255.255.255.0
[global]
Host Allow= 192.168.1.0/255.255.255.0
When I try to logon from NT, I try the following path:
\\SANDIEGO\helena
Then I type in helena and the password. The following errors would
show up: "The account is not authorized to login from this station".
I have been up three nights to set this one up without success, so I
would appreciate all helps.
Thanks.

I get the same kinds of errors here and don't have a clue why. It works fine
using older 2.0.36 version installs but when I moved to 6.0, things are broken.
In mine, it won't connect to the second nfs mount I have established on my
server but the first one mounts... partially. I made a root mount for nfs so
I could do adjustments and stuff via Midnight Commander, and it's utilities.
(makes for easy edits and all).
I can't see /usr, but I can see /bin. I can't see /home, but I can see /tmp and
/var.. Go figure.
My best guess here is some new bugs in this version that were reappearing. I'd
seen this before in an earlier version and a fix was released to address it and
it did. Now it's back and nastier than ever. Maybe someone compiled in old
code???!@!!

I have 2 machines on a 10-baseT network, a Caldera linux 2.2 machine and
a Win95 machine. IP addresses are set to 192.168.100.1 and
192.168.100.2, respectively. I can ping either machine from the other,
and I can telnet to the Linux machine. I can't however connect to the
Linux machine using a web browser. I had it working once, but made
changes at 3am without documenting them. I guess I was asleep. . . So
far, I have not set up DNS; my understanding is if I explicitly type an
address (192.168.100.1) into my browser, I don't need to. Anyway, it
worked once without it. The windoze machine also has a modem and a
dial-up connection that works just fine.
1.How can I tell whether the problem is in the Windows machine or the
Linux machine?
2. Could it be a route problem i.e Netscape doesn't know to look on the
ethernet segmet to find my Linux box?
Any help is appreciated.

This sounds like a problem that I was having with the tulip driver.
Type 'dmesg' at the prompt and see if your ethernet card is switching
from 10baseT to 10base2 or v.v.
If it is, pass the option of options=12 to the tulip module. This will
force it into 10baseT (only if your system is running 10baseT).
