Subject: wish script woes -- getting to know X
After my fumbling in the presentation at the last COLUG meeting
with that darn Enlightenment window 'manager', I have broken
down, and spent the last week using X, rather than shell as my
desktop.
The color is rather nice, although I have not yet arrived at a
strategy on what to keep in which pager panel/sub-window. (What
_is_ the proper nomenclature for the differing panels?)
Here is my issue:
I have a process which is cronned to dump a tail on a file to VC
12 periodically ... displacing the prior content there. I've
written a wish script which is working pretty well, but ...
I have re-written the app in a wish script. But while I am at
it, I decided to add functionality. I cannot find the syntax for
handing a file's content to an lpr pipe. I've read 'man n open',
and tinkered with it to no avail.
My current fragment code is:
#########################################
# proc Print {} {
#This does not work - TBD
.stat insert 0.0 "Printing ...\n"
set lpr [ open | lpr "w" ]
catch { exec tail -55 $env(HOME)/telcomp/log.cid.tail } output
puts $lpr $output
close $lpr
.stat insert 0.0 "... Done\n"
}
#
- ----------------------
.stat is a status window
=======================
The other issue is that a _cronned_ process cannot easily
determine which, if any, X DISPLAY to use [If no X is running for
a given userid, it should silently die]. Additionally there may
be permissions issues which I have not yet hit.
My thought is to scan 'w', and then the process table for userid,
and then walk the tree until I find an X running; that 'ps' line
appears to list the display, so then I can hand it to one of the
panels ('pager windows <?>'). I'd prefer to spot the LIVE panel,
but this may be asking too much.
But this seems like the hard way to do it.
Any suggestions on either issue in the group?

I bought a new issue of a Linux magazine... can't remember which
one... but it had a lot of information on setting it up. I don't
know, maybe it was the network experience I had from Windows 98, but
I doubt it!
Good luck!

Why not just have syslog write directly to /dev/tty12?

Can't tcl run a shell command (lpr /var/log/messages)? You may need
to have another tcl extension besides tk, such as tclX (which results
in wishx when combined with tk). Or pick a different language
environment, such as python....

Ever tried xconsole? Just send the data to /dev/console, and use
xconsole (or xterm -C) to see it. Don't try to mess with X from
within cron; make it client-server.

Hi keith !!
You are going to face a lot of security issues.
I do not know how to go about handling all of that.
Perhaps get it working so that the ipmasquerading is all working and do a
test setup with ftp on the linux box.
Then be prepared to tear it all down and rebuild it in a secure manner and
maybe add a 486 firewall.
The security stuff always was always too much for me as a newbie.
It was hard enough figuring out what inetd was all about and then your are
quickly advised to "killall -HUP blah blah <grep -blah -blah inetd.conf"
or do something dificult in order to secure your box. Confusion and RTFM
would result.
I am not advising you to run an insecure machine i am just saying learn
the basic setup first and then you add the security/firewall
stuff.
I found the RedHat Linux6Server book by Mohammed J Kabir M&T books to be
pretty good for explaining networking services on RH. I can loan you my
copy. My RH machine is in the shop, so I am giving SUSe a test run. Drop
me a private e-mail and we can arrange a book transfer.
There is an online article called "armoring linux" i will find a link to
it. It gives you a good security overview.

The security issues are a valid concern, but luckily there are a
couple of utilities to give you a jump start.
By far the easiest way to configure IP Masquerading AND provide the
first modicum of security is PMFirewall:
http://www.pointman.org/pmfirewall
Once you're a little more comfortable with your system, check out the
Bastille Project
http://www.bastille-linux.org/
and then read this helpful introduction:
http://www.securityportal.com/cover/coverstory20000501.html
Best of luck.

Since those are standard progs that come with the base kernel stuff, perhaps
you should submit as a request to the kernel developers to make that change
(or make the change and submit the diff) and see what happens...
Well, it's a thought anyway.

The useradd and passwd utilities have nothing to do with the kernel;
they're userspace utilities. Don't bother the kernel developers about
them.

Subject: setting up automated linux installation
Does anyone have information on configuring a boot/root disk to do a
fully automated linux installation. I already have a working custom
boot/root disk. Now I'm trying to automate populating the file system.
The problem I'm having is:
resetting the root device from /dev/ram0 to /dev/hda1
I think if I could do this, then I could get the rest to fall into
place. Does anyone know how to do this.
Thanks,
