You want ipchains for this kind of thing. Much more flexible. Not bad to
have both though.

Mostly handled by the kernel itself. In the case of inetd, it listens on
certain pre-defined ports for connections. If it gets one (via kernel),
it uses whatever rules have been established by tcpwrappers config
files. The kernel itself has to get everything first. ipchains works at
the kernel level, while inetd/tcpwrappers is a system service that can be
turned on/off/configged in various ways.

Probably so, but most (all?) of the services controlled by inetd have
their own logging facilities.

Subject: Help with NMAP and its results

I have run NMAP on several systems, including my home Linux box, MS
Windows NT 4 and 2000 systems, some Sun workstations, and a few Macs.
Each time I run it on said systems, I get different results:
TCP Sequence Prediction: Class=random positive increments
Difficulty=840322 (Good luck!)
Why do the Class and Difficulty variables change for each run on the
same system? What are their dependencies? How are they calculated?
I've emailed the author but have yet to receive an answer. I've glanced
through the source code but would need more time to trace the variables.
Thanks for any answers.

Am trying to install UT on my Linux PC but after struggling with getting

I can't just copy it off the Windoze version can I? Can somebody e-mail
me a sample of what the ini in Linux is supposed to look like? Or would
they be identical?

Check your preferences in Real Player 7. It has setting for OSS sound

I would suggest adding more ram to the system. You have an awful lot of
storage in the system and not a lot of memory. I would have to think that
you have processes or tasks occurring that would require more than 128 mb
of ram. I would suggest an upgrade to 256 mb or 384 mb of ram. The HD
light staying on during the crash could indicate excessive SWAP file usage
locking the system up due to not enough memory.

If you get an answer off-group, please clue me in as well. Every scan I
have ever done (friendly ones) ends with 'Good Luck!'. The difficulty
number seems completely random, and is higher with the more ports found.

I've fixed the last problem (clash between spinlock.h in asm/ and linux/
by renaming the file in asm/ and substituting a file with a single
carriage return.
Now I've progressed to a compile error in the USB drivers. I would
presume this relates to some of the choices I made in the .config file
relating to the USB options. I'll play with that again, but if anyone
has any input, I'd appreciate it.

The point is that telling the newbie "read the FAQ" is more useful than
answering the specific question posed - b/c reading the FAQ will answer this
question and the next 7 that the newbie will have. I.e., the real point
being made here is that it would be better if the newbie would post "Hi, I'm
a newbie - what should I do?" rather than any specific question. B/c then
the answer would be: "Read the FAQ - it is located at http://blah.blah.blah"
The newsgroups that are dedicated to being what the Usenet classically is -
that is, a place for smart people to discuss amongst their peers - do
maintain a pretty good discipline about this sort of thing. As the poster
said, if the question is in the FAQ, the answer is "read the FAQ" and
everybody is better off for it. OTOH, newsgroups whose purpose is to bring
in the masses, will generally not follow the discipline.
But, hey, look on the bright side - at least with Linux, it is still farily
small and self-contained. If I have a WinXX question, I don't even bother
trying to use the net - I know that there are likely to be 80,000 newsgroups
and I'd have to wade through thousands of layers of "How do I turn the
computer on?" - a question which, I suppose, makes "How do I boot from above
1024 cylinders?" seem positively erudite...

Try asking over in comp.arch.embedded. I'm pretty sure there are some

If you're using a WinXX machine with these programs, then ask this
question in a WinXX newsgroup, or read the online help that should be
included. Personal experience is that ACraptek's CD-burning stuff is
horrible; can't say much about Nero.
Under Linux, it's much much easier to burn an ISO image. Just get
cdrecord installed and set up, then:
cdrecord -v dev=/dev/sg0 speed=4 cdimage.iso
Edit the dev= and speed= options to conform to your CD-R(W)'s location and
maximum speed.
