Yeah, what I want to do is to be able to close the X session, close all
X's and not have gdm still running as a daemon. So...I did some digging
around and found
1) No man entry for kdm (that figures)
But I found in my rc.d directory a line...
kdm -nodaemon
>From there I found /opt/kde/share/config/kdmrc
And edited the line for restart to
Restart=exit
Shutdown=reboot
Now Restart on the kdm menu takes me back to a prompt nicely, but I
still have to do a CTL-C to get back to a prompt. But now ps -aux shows
no kdm hanging out.
Anyway I'd like to chain a command on the line with 'Restart=exit' to
do this. Is this possible?
BTW, this will make you sick :)
I created a little startup script (I'm a lazy typist) called
'win' <ACK> ...it just has kdm -nodaemon.
But anyway, at least I can explore the different desktops or switch
around to suite my preferences. KDE is the best one as also StarOffice
seems to be strongly connexted to it. But, alas, no system sounds for
Slackware 7 (and 4 either). Enlightenment sounds are great. Gnome
sounds like crap.
I also add I amazed at how rapidly Linux is evolving. My first Slack
distribution sported kernel 1.2.13 :) Things are changing so fast now
about the time I get one setup right it's time to get another
distribution and the changes have been huge lately.

I just got an order confirmation of some Linux
CD's from "Linux" Systems Labs. When I tried to read
the jumbled mess of lines, I thought I'd check the
headers. Sure enough, Microsoft Outlook. What other
program could do such a lousy job of sending email.
I bet they've got a nice little Windows NT office
network there. I should have put in my order for
the new Windows Me. I bet they have it in stock.
What are they doing using this stuff? Remind me never
to do business with those dopes again.

This is an old, and totally bogus argument.
ASCII BS (the character) is indeed \010, aka character 8, aka ^H.
But that has absolutely nothing to do with the _keyboard_button_ that
often has a back arrow on it, and also often these days has the text
"Back Space" on it.
And guess what? People _expect_ it to _delete_ the preceding character.
They'd be really upset if it just backed up over it, which was the
original TTY behaviour (ie ASCII BS is truly historically just a cursor
movement - and in that sense it is truly closer to the "cursor left" key
than to the key many people know as "Backspace").
The way you did underlined text (sometimes still used) back in the age
when ASCII was invented, was to write the character, send ASCII BS, and
write a underscore. Kind of like t^H_h^H_i^h_s^h_.
The BackSpace _keyboard_button_ is something else altogether these days.
That, on vt100 terminals (which is what the Linux console and xterms
emulate), generally sends the ASCII DEL character. The key that is
marked "Delete" sends the vt100 sequence for the delete (^[[3~, I
think). It does not send the DEL character. The way to get ^H is to
press control and H at the same time.
Note that keyboard mappings are seldom the same as "ASCII mappings".
The classical example of this is CR/LF, where there is again a big key
sometimes called "Enter", and sometimes with a curved arrow, and
sometimes with both. And depending on the day of the week and the
particular terminal, that key will send either CR of LF or both.
And the "End" key usually sends _none_ of the ASCII characters ETX, EOT
or ETB ("End of TeXt", "End Of Transmission" or "End of Transmission
Block").
Also, why don't we have a "Cancel" key, even though that is what a lot
of people use "Escape" for?
It's tough, but basically the ASCII names do not match to the keyboards,
or vice versa. And using them as an argument is not very compelling.

Ok, you have two solutions.
1. if you have no critical data, format c:, nuf said
2.
If you do, on the other hand have critical data, remove the hard disk, it should be on
the side of the laptop and pull-out. Insert it into another bay , like on a tower
computer, which allows for this type of HD. boot up the tower, then it will recognize
the second hd as a slave, as d:/e: depending on network configuration and cd/dvd rom
configurations. remove any necessary files and reformat the drive, and dont mess with
the file aprtition sizzes next time unless making them bigger.
EMERGENCY Solution:
Throw dignity to the gutter and send the computer to Fry's electronics or something
like that and babble like a baby to them.
Enjoy your computer,

Hmm, I am not completely sure what all that means either. In
particular addresses like 10.x.x.x are supposed to be for private
networks and should not be visible on the Internet. However, I am on
a cable modem connection myself and get similar packets which I block
in my firewall without adverse consequences.
It appears that cable providers use 10.x.x.x for some of their routers
etc. (I can ping one of them from here). And they may use DHCP for their
internal purposes too.

Be advised that /dev/ttys1 is not the same as /dev/ttyS1, the link from
/dev/modem should point to this device.
I think the idea of disabling your com2 might not be such a good idea
and I would check dmesg to see if the ports are being recognized.

Date: Fri, 28 Apr 2000 21:13:21 GMT
Thanks for the note, but `uname -m` on Intel returns "i?86"
(?=4/5/6 etc) on Compaq-Alpha returns "alpha", which still
means I have to *know* that 'Alpha' is a 64-bit processor
and the i?86-s are 32-bit chips. I could easily hardcode
this in my script with a case-esac, but that may fall
apart when the ia64 comes out! :)
I guess what I'm looking for is more along the lines of what
`getconf KERNEL_BITS` does on HP-UXs (returns nothing on32-bit
architectures, and "64" on 64-bit machines). While 'getconf'
*is* available on Linux Intel *as well as* Linux Alpha,
unfortunately, "KERNEL_BITS"/"_SC_KERNEL_BITS" isn't one
of the valid variables in 'sysconf(2)'.
Oh, well. I'll go (kicking and screaming) with the hardcoding
option, I guess...
:-R.

I've compiled the kernel 2.2.14 to use the framebuffer device (for
Mach64 driver). It seems everthing is okay if I set the framebuffer mode
with "fbset 800x600-72". Unfortunatly I can't activate it thru
lilo.conf.

Subject: Hosting Multiple Domains
Date: Fri, 28 Apr 2000 14:26:05 -0700
I've recently been put in charge of setting up a RedHat 6.1 server to do
domain hosting for multiple clients but I've never done anything like
this before and so have a few questions. My server will act as primary
DNS, Mail, Web (clear text and SSL), and ftp server for all of the
domains. I pretty much know how to configure the Web and FTP stuff, but
where I'm running into unfamiliar territory is with the DNS and sendmail
stuff. Not to mention, I'm more of a Solaris and Slackware linux admin
and don't have to much RedHat under my belt.
As far as DNS is concerned, What would be the best way to set it up. I
currently am using master zone files for each of the domains and
pointing the master server for those domains to the IP address of the
server. The only "A" entries I've been putting in has been for
"www.somedomain.com" and I've benn adding MX records to point to the
mail server as well.
EXAMPLE:
blah.com. IN SOA 192.168.1.100. user.blah. (
956891576
10800
3600
432000
38400 )
blah.com. IN NS 192.168.1.100.
blah.com. IN MX 10 mail.blah2.com
Is this the right way to do this or am I doing it wrong? I have
noticed that so far, the only things that will resolve is the servers
own domain and hostname. None of the other entries will resolve
correctly either from the server or the internet including othe "A"
entries in the servers domain.
The other question I have is in regards to sendmail. How do I set it up
to handle multiple domains. I also need to configure it send all mail
for each domain to the domain owner's e-mail address. Is this possible,
and if so how do I do it.
Any help on any of the above issues would be GREATLY appreciated.

Chris,
A few questions first and assumptions.
1) Win98 machines is currently connect to the interest via some ISP.
2) What Linux distribution are have you installed? IE> Red Hat 6.x SuSE?
3) You need two 10/100 BaseT NICs in the windows and one in the Linux box.
4) You need a HUB or one cross-over patch cable. (pref. HUB)
5) Make sure your NIC in the linux box is supported by the distro
EtherLink or Intel Pro 10/100 are easy.
6) assign static address to linux 198.162.0.2 netmask 255.255.0.0
gateway/router 198.162.0.1
7) if you are this far .....and/or you don't know how to configure
the interface on the linux box, let me know. I will help but I need to
know your distribution.
8) In the Wingate application, I hope you have the manual, set up the
ip forwarding and clients information.
