I think that you may use linux booting floppies to
* mount your hard drive
* create /etc/passwd with root entry
* reboot I conduct further recovery in single user mode
Redhat: use recovery options when you boot from installation
floppies.

Good point... but I like the bit about *well-documented OS*! Since when
has Micro$soft had a "well-documented" OS i.e. you don't have to spend a
hundred dollars on books! Besides, you can't get better documentation
than free source-code! (oh, and any bugs actually tend to get *fixed*!)
Just thought I'd add my 2 bits worth in!

Subject: IP-masquerading
Date: Sun, 18 Apr 1999 11:02:15 +0200
Hi!
I have to following problem: I want to set up a linux server to call my
internet provider and connect my win98 machine to the internet. Now I have
the problem that I was not able to get e.g. ICQ, Netmeeting and some other
software to run on my computer.
I think my linux server doesn't know to which the IP packages to send to.
The situation is that I can send ICQ-Messages, but not recieve.
Is it possible to set up the server that way, that I can use all these
services or is it impossible. Maybe I can configure my server to that all
unknown IP packages are sent to my win98 machine... This could be a work
around if it's possible.
Can anybody help?
Thank you, Marc

Hi!
Does anybody know anything about a telnet client which fully supports the
telnet features of Suse 5.3, e.g. to display the graphical boxes e.g. of
yast and other applications like mc correctly and one with which the
keyboard
has the same functionality as on a linux to linux connect. At now I use
SecureCRT in ANSI mode, but the textboxes are not drawn correctly and the F
keys don't work.
I already have a linux server down my cellar and don't ever want to start
linux on my win98 computer to configure... So, is there any solution? Can
anybody help?

Comparison Report
Certifed Performance
dont-mind-linus.sponsoredme-craft.com
Performance Comparison:
Windows NT 4.0 Workstations
and
SuSE Linux Kernel 2.0.36
Executive Summary
_SuSE Linux Kernel 2.0.36 is 13 times faster then Windows NT in application
performance_
Dont-mind-linus.sponsoredme-craft an unindependend test lab tested the
application performance of Microsoft Windows NT 4.0 SP4 workstation and SuSE
Linux Kernel 2.0.36 on two different test systems:
Testsystems:
Linux Hardware:
Pentium 133, 80 MByte Ram, 6 GB Harddisc
Linux Software:
unmodified 2.0.36 kernel as shipped by SuSE 6.0
Windows Hardware:
Pentium II 266,128 MByte Ram, 4+2 GB Hardiscs
(note: the faster system for NT was chosen to give NT a fair chance to keep
up)
Windows Software:
NT 4.0 Workstation Service Pack 4.0
To keep the influence of running daemons/services as small as possible the
programsuite to test the performance was very short. And to avoid speed
differences due to different compilers a interpreter namely Perl was
choosen.
Testprogram:
on Linux running in a text term with perl version 5.005_02:
> time perl -e 'print "start\n";while(1) {} print "end\n"'
on NT running in a cmd window with Activeperl 506 (5.00502)
> perl -e "print \"start\n\";while(1) {} print \"end\n\""
Testresult
Linux:
real 0m0.230s
user 0m0.220s
sys 0m0.010s
NT
Averall time: 3 s
To get these timing results the following key sequence was typed after
starting the test suite:
on Linux: <ctrl-c>
on NT: <ctrl-alt-del> <alt-t> <alt-e>
Linux Notes:
The syntax of the program is straight forward, no special remarks.
NT Notes:
1. The original testprogram gave an error message:
'Can't find string terminator "'" anywhere before EOF at -e line 1'
So it had to be modifed in the shown way.
2. Because of a missing timer programm, the time for the benchmark was taken
by hand.
3. Using the mouse to bring up Taskmanager and hit the "Endtask"-Button did
not improve the performance.
Conclusion:
For normal applications is Linux 13 times faster then Windows NT.

Subject: RAS Access from Win 95 to Linux via ISDN
Date: Sun, 18 Apr 1999 14:15:03 +0200
I want to access my linux server via RAS from a windows 95 client.
Maybe I am silly but I want to use ISDN instead of a modem access.
What I did up to now:
1) Install a ISDN card on the linux pc. Card seems to work. No errors
during startup
2) Install RAS and AVM NDIS WAN Port on the Client. Test session to
AVM is working. So I assume no errors in the configuration.
Now, when calling the Server I can see that the call is accepted
from the linux server (message in /var/log/messages), but anyhow
no connection is assumed.
I have no idea about the TCP/DNS configuration of the RAS / Linux.
Can anybody help me with a working configuration or a document about
this topic.
thanks alot.

Subject: About subnet configuration...
I'm now have a bit confuse of subnet setting, If I want to make 4
subnet in a class C
IP, then I make the 2 higher-order bits for subnet, that's 11000000...
Then...is that:
00xxxxxx = subnet 1 and the ip can use in this subnet would be 1-63
01xxxxxx = subnet 2 and the ip can use in this subnet would be 65-127
10xxxxxx = subnet 3 and the ip can use in this subnet would be 129-191
11xxxxxx = subnet 4 and the ip can use in this subnet would be 193-254
And the subnet mask should be 255.255.255.192
Am I right? But someone told me that the first and the last subnet
cannot be
use, so just have 2 subnet can be used in this case, and just 126 ip can
be assigned in
this case, is that true and why?
I'll so appriciate if someone can tell me more detail on it... =~~~>

I'm not sure exactly what you're trying to do, but a single DNS can be the
primary name
server for multiple domains. Under Bind8 just add another zone to
named.conf
and under bind4 add another "primary domain.com db.file" entries in
named.boot .
Having multiple seperate DNS on same system would probably require mutiple
instances of named with separate config files and zone file. I've thought
about this for security reasons, (inside DNS and separate outside DNS), but
it was simpler just to put it on another machine.

Subject: Re: Cable Modems
Date: Sun, 18 Apr 1999 15:32:18 GMT
I'm not sure where you get your cable service from but mine provides up to
1.5 Mbits/sec to each user on a given node (downstream speed). The upstream
speed is capped at 192Kbit/sec. They actually installed a 30Mbit/sec
capability to each home. There are a number of homes on the cable service,
node dependent, so you might not always achieve the 1.5Mbps speeds but in
the worst speed performance I've seen in our neighborhood was 100Kbit/sec;
slightly slower than ISDN but certainly faster than V.90 [V.90 in the US is
capped at 45Kbit/sec full-duplex by the FCC - at least it was when I last
checked at the end of last year and might have changed lately].
The idea of cable modem like mentioned below, which is the same in my area
[cable modem part of the service], is a benefit, at least, to me. They take
it back when I leave or cancel the service. ADSL in our area is provided by
Bell Atlantic and they want you to sink $325 to buy their ADSL modem. Big
startup cost for ADSL as compared to less than $100 for installation of the
cable modem. Plus I don't have to worry about technology upgrades -- my
cable service does that.
Now what does all this have to do with Linux other than using Linux as a
firewall/router?

check loaded modules with lsmod
you can load modules manually in your /etc/rc.d/rc.local with insmod or
modprobe.
see man insmode, man modprobe
this might look like:
insmod -o eth0 /lib/modules/KERNEL-VERSION/net/ne.o
(if ne.o is the correct module for the ne2000 - I dont know)
forget the redhat-configuration-tools. it just mess up your system and
you dont know what happening at all.

It's iffy without seeing the chat logs and chat script. You can try
replacing an expect/send CONNECT '' with CONNECT '\d\c' . You
can make sure that what the ISP sends is "username" and not "login", or
perhaps "Username" since case makes a difference in any *nix.

Haven't seen Exchange Server, but I use AtDot (http://www.atdot.org/), it

I have posted some days ago to this same ng the maillog (that is, before I

not a *friendly* packet. I have also sent a mail to the admin of the site
