if mkisofs disk reading and filesystem construction process stalls out
and your write buffer runs dry, you've got yourself a (lousy) coaster.
if you can't spare the 700MB for the iso image, you can't have much
room for anything else you're doing. it may be worth spending $100
for a 9GB hard disk.

You can limit users to their home directories in FTP, but in a shell, you
have to setup a root directory for them with all the programs/libraries
they'll need to use the system. Per user? this could be a few 100MB per
user, easily.
My point? It isn't worth the trouble to setup chroot'd shell users. just
don't give 'em a shell

You can do a restricted shell, but again, you have to do things like not
allow users to run their own binaries, and your system becomes useless. I
hope you aren't charging for these shells

Thanks in advance for your help.
ls -lni gcal gives the following:
1100523 c---r----- 8223 8224 8224 32, 32 Jan 30 1987 gcal
I don't understand the 8224 in the user and group columns either as
there is no uid/gid of 8224. Things don't look right to me.
I have tried everything I can think of to try and delete this file but
it always gives me a "Operation not permitted" error.
I have tried rm -f gcal to no avail.
Can any one show me the syntax to remove this file?

You need a kernel that supports a.out files and the proper libraries
(libc.so.4 for a.out and whatever the X libs are for that era).
Since Doom is now GPL'd, you may want to look for one of the more recent
versions like lxdoom to avoid this. See freshmeat.net

These days all Linux executables are in the "ELF" format (run something
like "file /bin/bash" to see "file"'s output on them). This executable is
in the obsolete format usually (poorly) called "a.out". Your kernel needs
to support this format, either by having it built in to the kernel directly
(CONFIG_BINFMT_AOUT=y) or by having the "binfmt_aout" module (available
and) loaded.

(Because of the former, this output might not be reliable.)

Subject: debugger for seperate files
From: green bird <[EMAIL PROTECTED]>

Hi, there,
Is there any debugger in Linux for a source file which calls
other functions and these functions are in other seperate files?
It seems that gdb can only debug a huge single source file.
Thanks.

Certainly have. Apart from using it on my company website for handling
the news, I have developed a full ecommerce system on my amiga using
it (can be seen at http://www.savilleflowers.com/) along with
numerous other cgi scripts. I did a nifty script to parse the BBC
news pages and download them locally (along with images) so I can read
offline. A lot faster than going to about 8 news pages and reading
them online. I just find it really great to use.
The newer Rebol/View beta which is now out for the amiga has GUI
capabilities on top of the core capabilities is quite neat too. Nice
versions of chess and minesweeper have been programmed for it.

I've used gdb on projects with anywhere from tens to hundreds
of source files in multiple languages (C, Assmbly, Modula-3),
and I never had any problems. What exactly happens when you
try to debug a program built from multiple files?

The website is done using rebol. Paul is listed as one of the

I suggest you rephrase your question with more care. The above makes no
sense without considerable context, all of which is lacking. Also
please separate your sentences with full stops! Fortunately I got a
glimpse of another reply in this thread, so I can guess what you are
trying to say.
If your telnet server is dying AFTER you have supplied a password, then one
would suspect that there is either
a) a lot wrong with one of your login scripts.
b) a lot wrong with your typing skills.
Based on the evidence so far, the latter would seem most likely ...
but look at the daemons logging output to find out more.
