Connection problems


I just recently installed Ubuntu Netbook Remix and everything works well. Including Internet for firefox but not for a program named MarketMaker. It is very important that I can get this program work 100%.

The program (MarketMaker) can sometimes connect and sometimes it can't. I sit a school now, using a wireless connection with 62% connection status. Downloading files with firefox I can get speeds up to 1 Mb/s and the files never get broken.
Using firestarter as firewall and it does get better if I close it but still connection timeout.

Have you any clue what the problem could be?
Can there be something wrong with iptables? In firestarter, marketmaker have grey letters meaning: Connections classified as harmless. This class consists mostly of broadcast traffic.

Doesn't marketmaker use their own servers? If so, then the speed would depend on those servers. You're running this as a web application, yes? (from Firefox?). On their website they claim they are now using new high speed servers so maybe the performance with improve.

It is an .exe file that I'm using under wine.

But do you think the problem is my computer? It is a Aspire One laptop.

I don't understand. Maybe we are talking about 2 different marketmakers. Can you give the website of the software you're talking about? I'm talking about this one: http://www.marketmaker.uiuc.edu/
cheers,

I found this aswell:
"Does Marketmaker® run on Macintosh or Linux?

Presently it does not, but it is our intention to release a version of Marketmaker® for the Macintosh OS and Linux. The reason the Mac and Linux versions are not yet available is because the version of SunJava for the Macintosh and Linux is not compatible with the latest version available for the PC. When the versions are compatible, our development team will then begin work on building Macintosh and Linux versions. It is possible to run Marketmaker® using emulators on Linux and Mac, but we cannot officially support these installations and offer no warranties/guarantees."

But I am using wine, shouldn't it work then?

I have no idea. I have never used wine. It might slow down your connection but you'll have to ask someone who actually uses it to see if that is normal. If your connection speed is normal when you're not using wine, then it's either wine itself or the way wine runs this particular software.

From what I saw on the link I posted, it seems to be able to run as a web application. Can't you use that one or isn't it the same thing?
cheers,
jdk

The web application only works in UK and not in sweden.


This program is very strange because I can use it without any problems on Linpus.

Marketmaker uses Java and I am not sure if Java is installed on my system.
When I am trying to install it this output comes out:
Code:
sudo apt-get install java
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Couldn't find package java

I don't use a debian package for java. I get it off the sunsite. Just untar it in a temporary folder and run the installation script. It's dead easy to do. You can get it here: http://www.java.com/en/download/manual.jsp and choose the linux version (32 or 64bit).

If you'd rather use a .deb package it's not called java but rather sun-java6-jre (at least on debian repos it is) so
Code:
sudo apt-get install sun-java6-jre
should do the trick for you.

Cheers,
jdk

Didnt get any better... =(

As I said before the program starts and everything works fine. It is just it loses the connection from time to time. It is connected in 0,5 seconds then loses connection then it tries to connect again and stays connected for 0,5 seconds and drops again.

Sorry about that danne but I don't have any other ideas. You might write to the devs of Marketmaker and ask them. Also maybe if you can run it under some virtual machine environment... sorry I couldn't be of more help.

Thanks for all the help you have given me. I really appreciated it.

BTW!!! You said something there! Remote desktop, if I can remote my windows computer with Marketmaker installed then I can use it without any problems. The question is how can I remote a windows computer using Ubuntu Netbook Remix (gnome)? Do you got any suggestion how I can do it?


There most be something wrong with the firewall, because I can't connect to marketmaker at home with my wireless network there either. I am using firestarter as firewall, do you know how to make a port forward for a certain program?

Question #1. I'd suggest starting a new thread on that with a good descriptive title like:
"Remote login to a windows host using Ubuntu Remix" or something like that.

Question #2. I use a browser interface to talk to my router. On of the things I can do is port forwarding. It's quite simple. I just have to specify the port and the machine and poof! It's done. I don't know anything about your setup so I can't help you there.
Cheers,
jdk
