Subject: setting up internal LAN
Date: Tue, 1 Aug 2000 18:46:44 +0100
Hi all,
I am having a problem with setting up and tesing my network. I set
up my network within our LAN here at work.
internet-------outside Lan--------------|firewall
system|------------------internal LAN
/
\ \
192.168.1.38
192.168.2.1 192.168.2.2
.Where the firewall sits on the Linux box, is where all my smtp,www,and dns
will be controlled. The pc (192.168.2.2) can
ping the internal address(192.168.2.1)
From the firewall i can ping an Internet System.
Now I come to a problem.
When i turn off ip_forwarding i can't ping the outside address
of the firewall(192.168.1.38)
However when i turn on ip_forwarding i can't ping the outside address or
anywhere on the internet from 192.168.2.2
I think my problem is that these address are not valid on the Internet.
The Outside LAN is connected to the Internet Direct. How can I go about
giving the Firewall a valid address on the Internet on the outside to allow
the internal
addresses to access outside.
Any help would be very much needed

Subject: Very slow modem connection
Date: Tue, 1 Aug 2000 18:36:50 +0100
What can that be due to? OK my PC is only a P75 but the modem is a 56.6
Hayes Accura and under windows it worked just fine.
I'd like to download a wordprocessor and by my reckoning, WP 8.0 personal
would take ... 21 hours!
Hayes technical services say:
Had a look at the log file you sent, first thing i noticed was that the
atz string was still being used, check that it has been replaced with
at&f (not case sensitive). Nothing wrong with atz but we don't know what
the settings were previously. Maybe worthwhile dropping the port speed,
could be too fast for the port.
I've already changed ATZ to AT&F in my PPP0 settings.
If anyone can decypher what follows I'll translate his CV into French for
free!

Subject: Re: Installing SUSE via FTP?
Date: 1 Aug 2000 17:53:14 GMT
SuSE is not very helpful at managing small-scale installations
compared with some other distros, but there should be no particular
reason you could not limit a server-based install via ftp from YaST1
to just the essential items from the A1/A2 and N1/N2 sets, which
would yield you a bootable text-mode system with networking, and
then load up other packages (individually or diskset by diskset)
over the course of time, either by doing additional small ftp-based
installs via YaST1, or by using a recursive ftp client to download
the sets and then installing them from a directory on your hard
disk.
But by the time we would get all this work done, it would be hard
to justify not just shelling out a dollar or two for the evaluation
distro on CD to save the time, money, and frustration that
would go into doing an install via slow dialup ftp.
I installed Slackware once via dialup. Ain't *never* gonna do that
again. And in sheer size Suse dwarfs Slack...
All the best,
--Kevin

Well, a for-instance...
I've got two identical FIC motherboards, with the same amount and type of RAM,
Same vid card (essentially, one was a 3DXpression+PC2TV and the other had no
PC2TV) one with an AMD 233MMX, one with an Intel 233MMX... The intel was
faster.... MUCH faster...
Guess why?
I'd set the DRAM speed to FAST on the Intel, and left it at SLOW (the default) on
the AMD... I don't have any numbers to back this up, and I really don't want to
reboot either of them at the moment just to produce results, but the "feel" was
noticably sluggish on the AMD, until I found that little problem...
Now the machines perform roughly equal... Again, I don't have numbers, but the
feel is about the same, and if you ask me, the AMD feels a bit faster... but
only a little bit.
At any rate, the DRAM speed setting affected performance, making one of two
otherwise nearly identical machines perform very differently.
Of course, I could just be smoking crack...

no, no, it's not pentia. that's plural. mandrake optimizes for *the*
pentium -- as in pentium classic.^1 this specifically excludes
pentiumpro, pentium-ii, celeron, pentium-iii &c. i586 != i686.
[1] ok maybe the old mmx classic version slips in there too.

First, make sure that your X server generates the [Backspace] event if
you hit the Backspace key and that it generates the [Delete] event if
you hit the Delete key. You can check that with the utility xev which
you can start from any xterm. Start xev and then hit the Backspace and
the Delete key and look at the output. I'm pretty sure that the output
will be as you'd expect - that insures that all X programs (including
Emacs) will work correctly. (If however the Delete key sends
[Backspace] and Backspace sends [Delete], you need to fix that with
xmodmap first.)
If bash runs in an xterm, bash's input and output is connected to
something called a pseudo terminal. (It's called pseudo because Bash
thinks it is connected to a physical terminal, while in fact its input
is generated and its output is consumed by a program, xterm.) Every
terminal, pseudo or not, has an erase character used to delete the
last character. To find out what they erase character is in your case,
say
stty -a
and watch for erase. ^h means BS (Control-h or ASCII 8), ^? means DEL
(ASCII 127). You want ^? as your erase character. You can either say
stty erase '^?'
(type it in as you see it, caret followed by question mark)
or you can tell xterm once and for all what you want: put a line
like
XTerm*ttymodes: erase ^?
as root in your /usr/lib/X11/app-defaults/XTerm or in your personal
$HOME/.Xresources.
Now, if you hit the Backspace key in an xterm running bash, the X
server sends the [Backspace] event to the xterm program, and xterm in
turn translates that into some ASCII character or character sequence and
passes that on to the shell, via the pseudo terminal. You need to find
out what that character sequence is: type "cat <Enter>", then type an
"a" and hit the Backspace key, then type <Enter> and Ctrl-d or Ctrl-c
to get out of the cat program. There are two cases:
1) If the "a" went away, your Backspace key gets translated into the
terminal's erase character, which we just set to DEL. This is good.
Continue below.
2) If something like "a^h" or "a^[[3~" appeared on your screen after
the cat excercise, your xterm doesn't translate the Backspace key
correctly into our erase character ^?. We fix that by putting
XTerm*VT100*translations: #override <Key>BackSpace: string(0x7F)
as root in your /usr/lib/X11/app-defaults/XTerm or in your personal
$HOME/.Xresources. (0x7F is hexadecimal for 127).
Now that xterm is fixed, if the bash input line still doesn't behave
right, it's because your .inputrc is screwed up (bash, unlike some
other programs, ignores the setting of the erase character, it only
believes what it sees with its own eyes in .inputrc). So, delete
everything you have in .inputrc because there's likely a lot of cruft
in there by now, and insert the line
"\C-?": backward-delete-char
Then start a new xterm and it should work. If you want to use other
fancy characters in your bash, such as Delete, Home, End etc., follow
the same procedure: use cat to find out what sequence the key generates,
then bind that sequence to some function in .inputrc.

i like
/boot 10-20MB *at front of disk*
/home 1-2GB or more as you've got space to spare
/ 4-5GB *including* /usr
<swap> 128MB
/boot is there to make the lame bios happy and let lilo load linux. i
use /home to store /etc and /usr/local (tar is good) during upgrade.
i let the / get totally clobbered during the upgrade. therefore, make
/home big enough to hold config stuff and other things you want to
survive the upgrade. the swap depends on memory and how much swap you
use, but 128 is probably a good starting point -- disk being fairly
cheap.
unless i have to (i.e., multiple physical disks), i don't bother with
more partitions because re-partitioning is a pain in the ass and if
you have a lot of small ones, some one of them is bound to get full
sometime.
i have tried the one huge ass parition. i have tried the many little
ones. this is what i've settled on as good for me.

Mark,
Have you looked at the access log? Also, the regular log, error_log is set
this way in httpd.conf should have a message of httpd starting and stopping.
If there are no start/stop messages in the log then Apache is not responding
because its not running
