If you want to use your linux box as masquerading gateway you also have to
add a masquerading entry :
ipchains -A forward -i <IP-external interface> -s <Network-IP-local-net>
-j MASQ
Good Luck,

If I am reading your message right...?
Windows 98 will send to the linux server the username and password that you
used to log onto win98.
This will only happen if you have windows family logon or MS client
installed in Control Panel/Networks.
When win98 first boots, enter the username and password used to log-in to
samba host.
Then open net-hood and open the linux server. Windows will send your win98
user info as default login. If it fails, you will be asked to re-enter the
password.
?? hope this helps :)

I used to run a DOS/Win31 pc networked into Linux using a packet driver (not
sure where to tell you to go for an Etherlink packet driver), a packet mux
(winpkt), and trumpet winsock. This will allow you to use a telnet client
(ewan was my favorite), wsftp, netscape, etc. (all those winsock clients).
And an Xserver for remoting display of xclients running on Linux.
I also had some machines set up using MS Client, which uses PROTMAN, etc.,
and allows File and Print Sharing with Samba over TCP/IP. Unfortunately,
the MS Client stuff is all "real mode" software... using up your precious
640K of DOS memory; so you don't have much memory left for applications.
All downloadable free software.

Date: Wed, 26 May 1999 21:26:05 +0200
Hello,
I've an RS6000 with AIX 4.3.2.
I've installed gnu-make, egcs 1.1.1, gnu autoconf from
www-frec.bull.com/.
I've bos.adt.include 4.3.2 installed.
I manage to compile apache 1.3.6, but PHP 3.0.7 and Mysql 3.22.21
complains when running make.
There seems to be a conflict in types declarations from egcs
includes and AIX include files.
here are the outputs.
============================================
For Mysql:
make
...
In file included from readline.c:26:

============================================
Any advice would be much apreciated.
may I try egcs 1.1.2 or do I have to cope with include files ?
Thanks in advance.

Install Windows for Workgroups? MS has a free TCP/IP suite for WFW,
probably still somewhere on ftp.microsoft.com; you should be able to
get it talking to Samba.

I don't think it does mutiprocessing. It does parallel processing, I
believe you need to run a parallel processing compliled program to

Hello;
I am a Master's of Managment Information Systems
candidate at Auburn University, Auburn, AL. I am doing research into
the problems encountered during migration from one network operating
system to another as part of my master's project .
I fully appreciate that this topic is not something one can read about
and
fully comprehend, but the goal of my research is to
provide a broad overview of problems associated with migration and not
in-depth tweaking methods.
To aid my research, I am conducting a web-based survey about Network
Operating System Migration. If you have participated in a Network
Operating System Migration, I would appreciate your participation in
my
survey.
Additionally, if you know someone who has participated in in a
migration,
please forward them a copy of this message.
To participate in this survey,follow this link:
http://www.auburn.edu/~mcgeeja/NOSSurvey.mv
If you have already participated in the long version of this survey,
please disregard this message.
If you have any questions, please email me at [EMAIL PROTECTED]
Any assistance you could provide would be greatly
appreciated.
Thank you,
John

I assumed he'd already known about that, and decided not to do it that
way [it _is_ a crappy solution, after all]. Everyone I know prefers not
having to type a port number explicitly.
