Subject: HELP! Problem to setup a Linux Server
Date: Tue, 08 Jun 1999 09:15:50 +0200
I have 3 Computers and want 1 as a Linux server the other as client
(also linux or WIN98).
The problem is how can I use the large disk on the server via NFS and
use it from
the others. A NFS mount from server:/usr to client:/usr seems not to
work properly!
Who can tell me how to setup the mountings and startup scripts?
PS : the system is running properly, I have no problems with nameserver,
yp-sever and other
communications.
Thanks a lot!

You could also try to add quotes in your pap-secrets like this :
*************************/etc/ppp/pap-secrets********
# Secrets for authentication using PAP
# client server secret IP addresses
"user@md3" * "mypassword"
It seems to have made a difference for me ;-)

IF Linux was that screwed up, it wouldn't be so popular with ISP's. If you
are having broadcast storms the first place to look is your NT boxes. I
have done dozens of trace captures with a GN sniffer and it is the NT boxes
that generate the broadcast traffic. The damned browser alone can be a
network butcher but when you add to that a lot of cross-mapping between
workstations and you have a recipe for disaster. I have seen broadcast
storms averaging 2000 packets per second lasting up to 10 minutes on
networks with only abotu 100 NT stations. Beleive me when I tell you that
can slow a swithed environment to a crawl.
The dozen or so Linux boxes on our network are almost invisible.

NBase-Xyplex use Linux in teh OSR8040 Switch Router. You can't get more
critical than that. I haven't had a chance to play with one but the specs
look better than the Cisco 5500's are those suckers are _fast_.

Subject: Conecting to a windows fire wall
Date: Tue, 8 Jun 1999 17:26:34 +1000
Hello All,
Here at work we have a windows nt fire wall and mainly
windows machine. Any way, I've managed to convince my boss that we need a
linux box to do some development work on and so far we've got it get a ip
adress from the dhcp. The last problem is to get it to talk to our fire
wall so it can talk to the outside world. The fire wall uses socks to
authenticate.
I was wondering if one of you kind ppl could tell me how to do this, or
point me in the direction of a HOW-TO or a web page that can tell me how to
do this.
TIA
Craig
ps sorry this is a bit rambly but I've had a long hard day of coding and I'm

Got the answer.
Changing the mtu only doesn't help.
On my setup I've also set the mru to 576.
This was the setup for the ppp0
location /etc/sysconfig/network-scripts/ifcfg-ppp0
This is the maximum recieve unit.
You can't set mru with ifconfig , only mtu.
So I edited the ifcfg file to use an mtu and mru of 1500
same as the ethernet card and all worked well.
(both where 576 the optimum for demon.nl)
Thanks for the suggestions.

First off I'm running RH 6.0 with pppd version 2.3.7. My ISP is running
Debian with 2.0.35. I'm using Redhat's ifcfg network configuration
system as my ppp interface. But once I connect it gives me 'IPCP:
timeout sending Config-Requests' and then terminates. What is happening
here? Any suggestions are appreciated. Below is the error log and my
config files. Thanks for your help.

Hello,
I try to use a network printer from a Dell Inspiron 7000 with Linux
RedHat 5.0.
What I've done :
Configure Printtool (Remote printer, correct IP number, correct
filters) and trying to print test page.
What I notticed :
Creation of a /var/spool/lpd/lp spooler directory.
The test page appears correctly in the spooler.
It does not appear out of the printer !!!!
If someone could help me, it woould be great.
Thanks in advance.
FRED.

The tests referred to by George lacks a lot of credibility. Besides NT
being tuned and the testers not being up to speed on tuning Linux Mindcraft
didn't bother to divulge that the test was being performed in MS Labs and
that the tests were paid for by MS. Refer to article "Lies, Damn Lies and
Benchmarks" by Art Wittmann at www.networkcomputing.com. Mindcraft is at
www.mindcraft.com
Mindcraft is now fighting a credibility battle and have 'posted articles
insisting that the company can't understand why the Linux community and
other went ballistic upon learning that the tests were paid for by MS and
performed in its labs'. Clueless?
The Mindcraft tests should be dismissed.

Subject: Windows clients, Samba server and generic postscript printer.
Date: Tue, 08 Jun 1999 07:07:18 GMT
Hello Everybody!
I am trying to create some kind of faxserver on my Linux box, and idea is to
create a 'virtual' postscript printer
with redirection of incoming postscript data to a fax software, with using
Ghostscript as converter PS -> G3 FAX.
Is there any way to create such a 'virtual' printer, which will be seeing
from Windows clients (95/98/NT) as
some kind of generic (or not generic) printer?
Or may be using postscript as 'common language' is a bad idea?
Or, may be, there are other not-email-based ways to send faxes from Windows
clients?
Thanks for any help

Subject: Trouble at Red-Hat 6.0 network laptop installation
Date: Tue, 08 Jun 1999 11:19:19 +0200
Hi !
After standard installation of Red-Hat 6.0 on a laptop, PCMCIA card
seeming well configured, I systematically get some trouble JUST AFTER
having set my TCP/IP eth0 card adress (delaying eth0 initialisation ...
[FAILED]).
In fact, all network services (DNS, HTTP, ...) seem to work properly and
the eth0 card is there with "ifconfig".
Having previously installed former Red-Hat 5.2 + kernel update versions,
I am persuaded this is simply a routing trouble : the system wants to
route either before the eth0 card is up or tries to see really (ping ?)
all related IP adresses (DNS, Gateways, ...) which are usually not
connected when I start my laptop.
Some magazines seem to say too that network route initialisation scripts
changed under Red-Hat 6.0, but they say very little.
Please help if you can. I will post the correct answer for newsgroup if
I ever get it.
Bye !
