What is Slirp?
==============
Slirp is a TCP/IP emulator which turns an ordinary shell account into a
(C)SLIP/PPP account. This allows shell users to use all the funky Internet
applications like Netscape, Mosaic, CUSeeMe, etc.
Unpacking and Compiling Slirp
=============================
To unpack Slirp type the following command at your shell prompt:
gzip -dc slirp-VERSION.tar.gz | tar xvf -
Of course, if you have the latest GNU tar...
tar xfvz slirp-VERSION.tar.gz
Where VERSION is the version of Slirp you are unpacking. This will unpack
the Slirp package into a directory called slirp-VERSION.
To compile Slirp type the following commands at your shell prompt:
cd slirp-VERSION/src
./configure
make
Notes:
if you do not intend to use PPP you can give ./configure the flag
"--disable-ppp". This will make a somewhat smaller executable.
if you wish to disable the MS type DNS transfer for PPP, or enable
MS DCC functionality, you will need to edit the created Makefile and
add/remove the options.
By default USE_MS_DNS is enabled, MS_DCC is disabled.
That's all there is to it. If the compilation failed, read "Getting Help"
below for information on how to get help.
You should be left with a file called "slirp", this is the Slirp executable.
After compilation, you can type:
strip slirp
to make the Slirp executable smaller, but this will also remove any
debugging information from the executable.
Here are some common ./configure/compiler/pre-processor/etc. problems and
suggestions for fixing them:
* "configure: error: can not run test program while cross compiling" (or
similar errors about cross compiling). This almost always happens due to an
error in the setup of the compiler. Look in the file config.log for clues
as to why it failed, or send it to your sysadmin for help.
* "gcc: xxxxxxx.p: No such file or directory.": This can be completely
ignored when running the pre-processor, and can probably be ignored in the
actual compilation. The .p files only contain the function prototypes.
* "gcc: warning: no previous prototype for XXX'": Again, you can ignore
this.
* "RUN_MAKE_AGAIN: not found ... *** Error code 1": This is normal. As
suggested, simply run "make" again.
Running and Quitting Slirp
==========================
Once you have compiled Slirp you can delete everything except the file
called "slirp", this is the Slirp executable. I suggest you also keep all
the files in the "docs" directory, this is where all the documentation is
kept. Copy the Slirp executable somewhere in your home directory (E.g.:
~/bin) then to run Slirp, you simply type:
~/bin/slirp
or ~/bin/slirp -P (for PPP operation)
(or whatever the full path to "slirp" is). That's it. Now you activate
your SLIP/PPP software, and start your applications.
All you have to remember is this: Once you run Slirp, your shell account now
looks exactly like a SLIP/PPP account (with some limitations of course).
Any documentation that you have telling you how to connect to a SLIP/PPP
account is completely valid for Slirp as well.
To quit Slirp you simply kill your SLIP/PPP software and type five 0's
(zeroes), with a 1 second gap between each zero. Slirp will then exit and
you will be back at your shell prompt.
You can also "disconnect" Slirp by typing five 1's (one's), with a 1 second
gap between each. This will disconnect Slirp from your shell's terminal and
put Slirp in the background. Later, you can type "slirp -l 0" to
"reconnect" Slirp again. Please read Section 10, "Load-balancing" and
Section 11, "Link-resumption" of the Slirp manual for more information.
Slirp has lots of options available, so while this will mostly get you
up and running in the first instance, reading the manual is worthwhile.
Files in the Slirp package
==========================
Here are the list of files you'll find within the slirp package:
COPYRIGHT Conditions of the Copyright on Slirp. Please read this.
ChangeLog Descriptions of changes made to slirp from version to
version. Also details all contributors, and their
contributions.
IMPORTANT Information about who's the latest maintainer.
(Hint, it's not Danny)
README What was this file.
README.NEXT This file. Really!
docs/CONFIG List of configuration options (probably out of date)
docs/alt.dcom.slip-emulators.FAQ
This is the FAQ (Frequently Asked Questions) from the
newsgroup alt.dcom.slip-emulators.
docs/slirp.doc The Slirp manual.
src/* The source code to Slirp.
Getting Help
============
There are several sources of help. First, read the Slirp manual called
slirp.doc in the "docs" directory of the Slirp package, especially Section
13, "Troubleshooting" and Section 14, "Answers to Frequently Asked Questions
(FAQs)".
There is also a Newsgroup dedicated to SLIP-emulators called
alt.dcom.slip-emulators. You will find lots of discussion about Slirp and
other "SLIP-emulators". The FAQ (Frequently Asked Questions) for
alt.dcom.slip-emulators is included in the "docs" directory, I would suggest
reading this as well.
The Slirp website (http://slirp.sourceforge.net) has some information
too. Go there!
A mailing list for Slirp development is hosted by SourceForge.
If you are intrested in pitching in, go ahead and subscribe.
If all else fails, send Kelly, the new maintainer, an e-mail
with the following information:
* Output of the command "uname -a" on the remote system;
* Operating System name and version you run on your PC;
* If it's Linux, the name of which distribution you are running and
which version.
* What compiler and which version you're compiling with.
HINT: If it's not GCC, then I will be tempted to have you switch to it and
try it again. Seriously, GCC is much better!
* Version of Slirp you are using (IMPORTANT!!!);
HINT: If it's a 1.0g or less, you really need to upgrade first. This is
what I'll say first -- Upgrade and try it again.
* If you managed to get Slirp running, run Slirp as "slirp -S" then try
whatever failed. When you exit Slirp, you should have a file called
"slirp_stats". Send me this file; and
* Anything else you consider relevant.
Don't send me core dumps. I can't handle 'em, and they may be for an different
system than what I have!!!
*PLEASE* include all the above information. If you do not, I may simply
press "d". I can't guarantee a response, but I will try my best.
Kelly Price and the Slirp Development team.
(Thanks go out to Dan, the previous developer.)
