#407 No internet => No xMaxima
The windows compiled version of xMaxima refuses to
work if a connection to internet is not available and
working. A message saying "Error starting Maxima: Could
not open a socket" is issued.
After that the window xMaxima keeps mute, no prompt,
no echo, nothing...
If we have no Internet connection how can we keep
working with Maxima through the xMaxima interface?

An active Internet connection is not required by xMaxima.
However, you must have sockets installed, working, and
enabled, because Maxima uses them for interprocess
communication. Firewall software may be closing off sockets,
for example.

Some of my students have reported this problem to me, too,
although everything on my laptop (WinXP Home Edition) works
fine - even without internet connection.
The only significant difference to their machines, I can
think of, is that I once activated XP's compatibility mode
for older programs (sorry, I don't know the exact words
since I am running XP in german - do search for
"compatibility" in the help menu and reinstall maxima with it).
Just one possibility.

Uli.

I wonder just how much network stuff needs to be active in
order to enable the Maxima <--> Xmaxima connection. It seems
like just having the network stuff running with the loopback
address (127.0.0.1) should be enough. Should be possible to
test by shutting down any other interfaces and then trying
to launch Xmaxima.

If internet on then wxMaxima normal start and solve expression.
Without internet wxMaxima notify "Not connected to maxima!".
Console application maxima normal start and notmal solve without internet.
If I right undestand wxMaxima need loopback 127.0.0.1
I'll send mail to fedore support about loopback.
I hope, that developers wxMaxima make notify that wxMaxima need loopback if it seems.

Fedora users should check if the file /etc/hosts contains the following line
127.0.0.1 localhost
If it does not, then it needs to be added.
