Careful. Unless he changed it from Slackware 3.6 and earlier,
syslogd is actually started in /etc/rc.d/rc.inet1 .
There is a syslogd start command in rc.M, but it isn't used
if networking is installed.

I had posted this article a couple of weeks ago, after listening, endlessly
about how NT couldn't SMP, or Cluster, or stay up 99.8% of the time.
"In 1998, the Microsoft Web site team achieved the long-term goal set in
1997 to attain 99.8% availability. When talking about or referring to
availability, we have two classifications to increase granularity: server
availability and user availability - both of which are equally important.
Server availability refers to the overall healthiness of the site's servers.
This means the servers are "capable" of serving a request; that is, the
server is not in an unknown or locked state and the INETINFO process is
functioning correctly.
User availability is the experience the user has when she requests a page or
data from the site's servers. Does she receive the response that was
requested? Examples of user availability problems include error messages
such as the 500 Server Too Busy error. When you're looking at server
availability, this is OK since the server is still responding. For user
availability, it is not."
They achieved the 99.8% availability of the site, with a very heavy load.
But you can draw your own conclusions.

Even worse --- a horrible failure of logic.
let X be an app. Then the "caveot" says
X is linux app ===> X is Solaris app
which Chad tries to argue. However, he does so by showing
There exists an app Y such that
Y is a Solaris app ===> Y is a linux app
does not hold.
Of course, that is not surprising. After all, VW beetles are cars, i.e.
X is VW beetle ===> X is car
while not all cars are VW beetles
There exists a thing Y such that
Y is a car ===> Y is a VW beetle
does not hold.
What he would need to find is something that is _not a car_, and yet is
a VW beetle (or _not a Solaris app_, and yet a linux app).

This is possible in principle, but potentially dangerous to the
health of your system. Be sure not to over-write any basic
library files that are already there. You may want to look at
recent versions of Slackware, which are still (alas!) libc5-
based, but which feature run-time support for glibc2. Not that
you'd want to switch your system, but take a look at the packages
and see how they did it.

Date: Thu, 17 Jun 1999 01:10:09 GMT
Hello,
I attempted to install a second network card under RH 6, and in doing
so, I somehow buggered my pre-existing network configuration.
The original card, an ancient ISA NE2000 card is on IRQ 11, and I/O
0x300. This was always running as eth0, with kernel module 'ne'.
The new card, an unknown LinkSys NIC included with a HomePNA package is
'supposed' to be on eth1, with IRQ & I/O port determined by probing.
Since Linux does not probe all cards if you have at least one ISA NIC
present, I specify the following LILO boot line:
linux ether=11,0x300,eth0 ether=0,0,eth1
Which subsequently causes the module dependencies not to be found upon
start-up, disabling both interfaces. In an attempt to at least restore
my original configuration, I disabled eth1, removed the appropriate
entries from /etc/conf.modules, and started Linux normally, but eth0
still cannot be established.
Can someone please help me out, before I go and buy an iMac (the fuchsia
one) :o
Thanks for your help.

Actually, they made an effort with DOS 4.0, but IMHO by then the
backward-compatibilty baggage prevented real progress, because there
were all these other applications hooking into interrupts to extend
DOS because it was so limited in the first place.

I think the complete lack of applications for Linux and the repeated claim,
in this forum, that Linux could run Solaris applications, they are available

IM(l)E query slowness is largely unrelated to CPU. Disk locality and

Provided you allow only your own hosts in /etc/exports and forbid
access to everyone else, making double-sure with ipchains (NB: protect
the nfsd port as well as portmapper!), then it isn't screamingly
insecure, but SSH is still better.

Not is you use SSH.

I'd use SSH, or the Cryptographic NFS filesystem (search the web).

demand fairness, demand a ban on using ms operating systems next time
there is an incident with an ms machine

Subject: How to reset modem after system crash?
Date: 16 Jun 1999 23:38:19 -0400
Reply-To: David Guertin <[EMAIL PROTECTED]>
Hi folks,
I've been happily using PPP over my modem for a long time on my home
Linux box. Then yesterday, while I'm connected to the network via
PPP, Oops! the power to the computer gets interrupted and the system
goes down hard. Ouch.
Upon restart, things come back to normal after fsck gets a workout.
Except that now the modem is no longer working. PPP says the modem is
busy. 'setserial /dev/ttyS2' responds with "/dev/ttyS2: Device or
resource busy."
OK, it seems there's still a stray lock file somewhere that needs to
be deleted. But where?? "find / -name '*lock*'" and "find / -name
'*LCK*'" don't turn up anything that looks promising.
Maybe I need to send a reset command (&D3 or something?) to the
modem? How? "echo \&D3 > /dev/ttyS2" just gives me the old "Device
or resource busy" message.
I'm stuck -- does anyone have any suggestions as to how to get my
modem functioning again? (This is a RedHat 6.0 system with a 2.2.5
kernel.)
Cheers,

I know that in order to switch to another terminal while already
in Xwindows is <CTRL><ALT><Fx>. Thing is, what if you want to switch
back to that Xwindows session? Whenever I use <CTRL><ALT><Fx> to go
back, all I get is a black screen with text. Is there a way to go back
to the graphical Xwindows session?
