There are IMAP clients (mutt, fetchmail) that can do NTLM
authentication (the encrypted challenge/response system used by
MS), so if plaintext authentication is a problem for the
powers-that-be, you can give on that point. Don't admit you
can handle NTLM at first. They'll probably come up with
"security" issues as the excuse to not enable IMAP.
Also, check to see if there's an SMTP server enabled somewhere.
There's got to be an MS box _somewhere_ with SMTP enabled, or
they wouldn't be able to get mail from outside. If you can use
SMTP to send mail, then you're half way there. The SMTP server
on MS Exchange might require authentication, but it's just
plaintext username/password in base64. I've got a patched copy
of ssmtp that will work. If you need it let me know.
I've also written a Python program that fetches mail via MAPI
and forwards it to an SMTP server. Unfortunately, you need a
dedicated Win32 box for each user who's mail needs to be
forwarded. Windows (even NT) is most definitely _not_ a
multi-user system -- despite delusions to the contrary in
Redmond. You can't have multiple instances of the program
fetching mail for multiple users, since you can only fetch mail
for the currently "logged in" user, and there's only one user
logged in at a time under Windows. What a lame POS.
If you want a copy of my mapi fetcher program it's at
ftp://ftp.visi.com/users/grante/stuff/mfetch.py
with a sample command line in
ftp://ftp.visi.com/users/grante/stuff/mfetch.bat
There's some hard-wired logic that converts our internal
Exchange-style addresses to Internet style, so you'll have to
change that part. I haven't yet figured out a good, general,
configurable address translation scheme.
It should be fairly easy to write gateway program that goes in
the other direction (SMTP->IMAP), but my MS-Exchange server has
SMTP enabled, so I didn't have to. ;)
Good luck.

"Don't worry about it" is my advice. System.map is used mainly to aid
in debugging kernel problems. There's one user-space program that I
know of (lsof) that uses System.map to do its thing, but in the main,
System.map isn't used.

Sounds like WinDOS has hosed itself. I'd guess you can try booting from
a bootable DOS disk that has COMMAND.COM and SYS.COM on it, then COPY
COMMAND.COM C:\WINDOWS\COMMAND\ and SYS C: .... you may wish to ask
this question on a WinDOS newsgroup, though.
BTW, Linux can read and write DOS partitions and has been able to for a
long time now. You can access your DOS partition from Linux and copy
your files to a safe place if you end up having to reinstall WinDOS.
See this group's FAQ or your Fine Manual for how to do this.

Yep, LILO's documentation says that error 0x10 means "CRC error -- a
media error has been detected." This is a bad sign, and often means
that the disk is going south. The fact that you can boot from the
floppy and not the drive is telling here.
If you're not quite convinced, boot from Tom's Rootboot or a similar
rescue system, and try doing this:
dd if=/dev/hda of=/dev/null bs=4096
If the command aborts at any time, you've most likely got a partially
br0ken hard disk. You can *try* and recover by doing "mke2fs -c" or
badblocks on all the partitions and reinstalling.... sorry this had to
happen to you.

Reply-To: [EMAIL PROTECTED]
Date: Fri, 18 Aug 2000 02:40:40 GMT
[Note: Followup set to the group I read most frequently]
As the subject indicates, I'm having trouble unloading a module that
just won't go away. I've got VMWare installed (version 2.0.2 currently),
and since upgrading to the latest set of Linux 2.4-test* kernels, I can
no longer unload the vmnet module, thus I can not upgrade versions of
VMWare or re-configure VMWare without removing the VMWare start entries
from /sbin/init.d/rc2.d and re-booting. I just hate re-booting Linux,
especially when my uptime starts to climb again (damned power failures),
so I'd like to find a solution to remove this module from the running
kernel.
When I attempt to run vmware-config.pl, it first calls '/sbin/init.d/vmware
stop' which returns this output;
blackdeath:~ # /sbin/init.d/vmware stop
Stopping VMware services:
Virtual machine monitor done
Bridged networking on /dev/vmnet0 done
DHCP server on /dev/vmnet1 done
Host-only networking on /dev/vmnet1 done
Virtual ethernet failed
I assume it's related to this problem;
blackdeath:~ # rmmod vmnet
vmnet: Device or resource busy
For the life of me, I have no idea what could be using this module. I've
tried shutting down any daemons or applications that could have anything
to do with VMWare, but to no avail.
What tool(s) are available to determine what's using a particular module,
and is there any way to force the removal of a module?
Thanks in advance!

Hello,
If you just want to try out Linux commands and utilities as a user and
possibly create a few user groups and accounts, I suggest you download
zipslack.zip ( a single file, about 36 Megs, expands to under 100 ).
No repartitioning is required.
Unzip the file into a FAT (DOS or Windows) directory, edit the
linux.bat file as explained in the readme file ( to tell Linux which
drive to boot from), and start it from DOS with the command Linux.
When you quit Linux (with Ctrl-Alt-Del) you're back in DOS ( or
Windows ).
Voilà ...

In short: you can't. Those are kernel structures and your user program
cannot access them.
struct sk_buff contains _ONE_ packet; note the data will
reside elsewhere, only pointers to it are in sk_buff. The
kernel links the sk_buff-s for a given device in a linked
list (I think it is a linear FIFO, not circular).
There are several ways to proceed:
1) instead of a user program write a kernel module. but you will still
have difficulty "grabbing" those packet sk_buff's because they
pass through rapidly and are only transient.
2) use an ethernet tap0-tap15 device. But I don't know how.
3) ipchains has a method for passing packets through a user program,
but I don't know how.
4) use tcpdump. despite its name it can dump all IP packets. Use
the option "-w -" and it will write all packets to stdout; pipe
that into your program and have it read stdin.
4 is obviously the easiest way to get access to those packets, if all
you want to do is monitor them.

Greetings,
I run Linux-Mandrake 6.1 on a Celeron 400. I have had a horrendous time
with netscape Communicator 4.61 and recently managed to get the standalone
browser (Navigator) 4.74. Installation was a breeze with no problems. The
directory i installed into was /usr/local/netscape/ . The old browser was
installed in /usr/bin/ with the library files in /usr/lib/ . Should i have
installed into the old directory?
Anyway when i tried firing up the new browser by clicking on the
exucutable in the /usr/local/netscape/ directory it gives me the following
error:
===============================================================================
netscape: program is version 4.74 but resources are version 4.61
This means that there is an inappropriate 'Netscape' file
installd in the app-defaults directory. Check thses environment variables
and the directories to which they point:
$XAPPLRESDIR
$XFILESSEARCHPATH
$XUSERFILESEARCHPATH
Also check for this file in your home directory, or in the directory
called 'app-defaults' somewhere under/usr/lib/.
============================================================================
I've looked for this 'app-defaults' directory but cant seem to find it
anywhere. Does anyone know of any solutoins to this?

Every time I've priced machines from Dell, I have 3, the Linux offerings
were always much more expensive than the equivalent Windows machines,
but it's true they were not exactly the same. Dell only offers Linux on
server class machines which use SCSI rather than IDE drives, which
drives up the price of the machine by a thousand bucks. In workstation
applications SCSI offers no performance advantages, SCSI is only helpful
in file server applications. The Dell desktops are completely Linux
compatible (unless you select the Winmodem option instead of the real
modem) but they are not offered with Linux.
