In order to uninstall LiLo ..is it the same to run SYS.COM and FDISK
/MBR in DOS.
Both commands can overwrite MBR which is LiLo resides?

The log files are determined by the configuration of /etc/syslog.conf,

*.=info;*.=notice /var/log/messages
*.=debug /var/log/debug
*.warn /var/log/syslog
This configuration sends chat messages to /var/log/messages along with a
few pppd messages, pppd link negotiation messages go to /var/log/debug,
and the occasional real bad error messages go to /var/log/syslog .
The files have to exist, "touch /var/log/filename", and when a new one
is created a "kill -HUP `pidof syslogd` is necessary to get syslogd to
reread /etc/syslog.conf.

Hi Frank,
No. sys will not overwrite LiLo mbr. There are two way of getting rid
of LiLo:
1. If you still have Linux partition up and running, login as root and
type lilo -u /dev/hda (where hda would be your boot partion) or
2. Boot with a dos boot diskette and type fdisk /mbr

Yes, thanks to PCI magic most, if not all multiport PCI ethernet

No, it has to do with shell expansion. Your second problem is because
you're pounding the server. Inetd probably killed rcp until it cooled
down. See your logs.

Michael,
For a little bit more than what you will pay for 3com cards, you can get
Intel's EtherExpressPro100 (eepro100 in short). You will have less
headache since it is compiled into the kernel by default with RedHat5.2 or
even maybe with SuSE ( I couldn't be sure about the later). We use eepro
in all our computers at work and it works great.

If you cant even ping itself (i.e. localhost), I believe you havent even got the
network setup yet. I mean the basic network setup. Do a 'netconf' (I dont quite
remember the exact command), and start setting it up. It will ask you for your
ip address, subnet, etc. Just follow the instructions. You might like pick up a
copy of the net-3 howto. It explains all these in there.

Ummm, I might be missing something... My Redhat 5.2, which is the latest

I'm having a hell of a time getting my PCMCIA ethernet support to work.
I've got a Dell Inspiron 3500 (I've checked out the online stuff on Linux
for Laptops) and I'm running Red Hat 5.2. I've tried editing
/etc/sysconfig/pcmcia and /etc/sysconfig/network but still no luck.
This is probably a question with an easy answer, but all the online docs say
to download pcmcia-3.0.6 so I did using Win98 since that's the only OS that
gives me network support. I've got a dual boot with Win 98. How do I get
the file I downloaded from Windows to Linux so that I can compile and
install it?

just one hint:
look in var/messages of the linux-server for any new warnings / errors that
appear when you try to 'work' with the mounted dirctories ( ls, cd ...)
might tell you a little more of what exactly seems to be forbidden.
you MIGHT try to mount the shares on your linuxbox itself - normally this is
nonsense but this way you might find out more about which side the
strangeness is on ( bsd or linux)

When I'm connected to my AppleTalk server running RedHat 5.2 and netatalk

folders on the server.
Instead of creating one alias file, TWO files are formed! A file of
filetype alias and a file of file type document are created. This only
happens in Mac OS 7.X - it does not happen with OS8.X.
Anybody else notice this? Is it a bug? Any work-arounds? Generally, how

<horrible strangling noise>
Ummm -- no. Instruction-level parallelism is extremely hard to
accomplish at anything above the chip level (that's what multiple
issue CPUs are, though) and when it is accomplished you won't know
it because it's not visible at the ISA level. That's what about
half of the transistors in a modern processor do. (The IA-64 jobs
will be a different story, with ILP visible to the compiler.)
SMP just has multiple processors closely coupled on a local bus with
shared main store, separate caches, cache coherency in hardware,
and all processors having equal access to all resources (no address
ranges specific to one CPU, no dedicated disk managers, etc.)
Part of the fun of SMP is scheduling threads to avoid thrashing
the cache. Threads need to be sticky (preferentially assigned to
processors which have the thread's working store in cache) without
being inflexible about it.

Keep in mind that a single 100Mb/s NIC is a pretty puny pipe compared
to even a so-so disk controller, much less a RAID array. If you're
setting up a server farm, you want to have a load-balancing router
feeding traffic to a whole bunch of servers. Since each individual
bitstream isn't all that fat, it makes sense to use LOTS of bitstreams.

I'm pretty close to getting my ppp server up. mgetty does a fine job of
answering the call (I tried for hours on end to get uugetty to do the trick
but it just wouldn't!), I have AutoPPP setup and it launches PPP fine.
However, the authentication fails. I'm sure the pap-secrets file is setup,
as such:
jack hostname hisPassword
where hostname really is the output of hostname.
jack also has a normal login entry in /etc/passwd. In the debuggin trail I
do see that the ppp was started ok, but that authentication failed even
though the username and password name are correct as reported. I have tried
using the "login" option in the /etc/ppp/options file and setting
"hisPassword" to "". I've checked that I can su to jack using his password
so I'm sure the password is OK. That's left?
Thanks

It appears I was wrong about this. Outgoing connections also stop
working. Incoming connections still work -- I can still telnet into
the box -- but I can't telnet out over either of the two ethernet
cards or to localhost.

I'm starting to suspect a problem with the masqerading and forwarding
that I've got set up. I have four machines set up to masquerade, as
they need to reach the outside independent of the proxy. I then have
a masqerade rule that allows all machines on the network to masq out
to port 110 on a certain outside server, for popping mail (a temporary
fix). I then have a few ip forwarding rules set up to allow 3
machines to use ICQ. Is it possible that there's too much masqing and
forwarding going on, and that's confusing the tcp in the kernel after
a while?
Thanks again,
Aaron

Hi, All!
How can I run UDP broadcasts (port 138) running between two subnets ?
Thanks,
Nickolay.
