The Davis Community Network (DCN) will hold an
"Introduction to Linux" class, presented by
the Linux Users' Group of Davis (LUGOD).
Monday

The class will be held at:
City of Davis Computer Labs
(Near City Hall)

Linux is a free "alternative" computer operating system
which is becoming increasingly popular in the server,
desktop and embeded environments.
Linux, and much of the software available for Linux are
known as "Open Source" products.
Open Source software is released under a license which grants:
* free (gratis; free as in price)
distribution of software, and
* free access (libre; free as in speech)
to the code behind the software
The class will be most likely be hands-on use of
PCs running Linux, and instructed by members of LUGOD.
The class is free, however space is limited.
To sign up, please visit:
http://www.lugod.org/projects/class/
LUGOD is a non-profit organization dedicated to the
Linux Operating System, and which holds regular meetings,
workshops, demonstrations and other events in Davis, CA.

I had trouble with that in SuSE 6.2 as well, but fiddled around and got it
to work...
Can't remember how though, so you'll have to help us all out with a few
tidbits of information...
What error messages do you get when you start it?

I have set up ipchains to deny all port coming into my linux pc.
However, when I sendmail or lpr a file, the mailserver and print server
will return TCP messages through ports from 1025 to 11xx. So, how
should I set the rules to allow connections to the mailserver and print
server? Thanks.

The file IS readable by emacs, vi, or whatever your favorite text

You do not need to reboot; that is a Microsoft error from which Linux
does not (usually) suffer.
If you change /etc/profile (or your ~/.bash_profile), it suffices to
logout and log back in again.

Some firewalls actually allow access to the higher ports, for instance:
/sbin/ipchains -A input -p tcp -s 0.0.0.0/0 -d <WhatEverIP> or <Network> 1025:
-j ACCEPT

Well, everytime the print/mail request is coming from different ports. So, if I
open the upper ports, say from 1025 to 6000, does it means that I lost the purpose
of secure my pc from others' access?

I've made an MP3 machine out of a low-spec box (DEC Multia/Alpha 166),
and it seemed that the best MP3 player for the job was mpg123 with the
GQmpeg front-end. It was easy to use on the 640x480 output to the
television and easy to control with the cordless keyboard or mouse.
At the time, XMMS was a bit CPU-heavy to use. It might be different now.
By the way, I had the Multia ethernetted to my main machine, which was
used as an mp3 server.

Providing that you have no services running in these high ports there
shouldn't be a problem, although you will have to be careful about the "rpc"
services as they hide on the higher ports. If you can identify a range that
the ports are using it would probably better than opening them all up, but
sometimes it is really hard to know what service is going to use what unpriv
port.

Hello,
Due to a crashdisk, I lost an html document figuring Tux, the linux

In fact the text was from the kernel sources, and only the color of the
letters made the penguin appear.
Does anybody know the page I am talking about ?
If yes could you please tell me where to get it ?

mkfs.ext2 rewrites the superblock, the block group information, and the
inode tables on a partition. If mkfs.ext2 was called with *EXACTLY* the
same options the second time (same block size, sparse_super set the
same) then a large portion of the data will still be there, just with no
organization to it at all. If mkfs.ext2 was called with a different
block size (4096 vs. 1024) then forget it.
mkfs-ing a raw partition is like building a filing cabinet. mkfs-ing a
partition that already has a filesystem on it is like taking the filing
cabinet and dumping its contents into a huge trash bin. If you have
text you need to rescue, you may be able to recover it by using grep on
the raw device. If you have binaries, in particular multi-megabyte
files consisting of compressed data (mp3s, JPEGs, tarballs...) then it
will be close to impossible.

Subject: ncurses with gdb??
Date: 27 Feb 2001 04:38:05 +0100
Hi, there,
I have a question on how to debug a ncurses program
using gdb.
I used "tty /dev/output_term_name" in gdb and then go
to "output_term" to let it "sleep 1000". Then I
returned to gdb to "run". But I always got
"Program received signal SIGTTIN, Stopped (tty input).
0xff318d4c in _libc_read ()" whenever I want to input
something in the terminal which will display the
windows.
What is the reason for this? What is the correct way
to debug ncurses programs with gdb?
Thanks for advice.
Davis
