FahMon (multi-platform app to monitor various F@h clients)

[benadderson]

Thanks for the clarification, that one had been bugging me for a while!

[Oak37]

Hi,
I came across a weird issue. I had FahMon setup on my Ubuntu 8.04 box and added a third client to monitor on another computer. When I added the location of the third client FahMon crashed and FahMon now crashes as soon as it starts up, the only error it produces is 'Floating point exception' when started through the terminal.

A bit more background info if it helps: Currently my Ubuntu box connects with my WinXP box through Samba, in this case the XP box is acting as the server. On my XP box I am running one instance of the console client and one instance of the GPU client. I'm sharing both folders containing all the relevant folding files which I'm able to browse and access through my Ubuntu box. FahMon worked fine when I added the location of the Console client but when I added the location of the GPU client it crashed and refuses to start up. When I start FahMon it briefly tries to download an updated edition of psummary.html but subsequently crashes. Any ideas? I'm going to try and compile it again, see if that fixes it.

The version is 2.3.2b

Since you're on Linux you can probably help debug this.

Compile FahMon again, make sure you do not strip the binary (by default it won't), and then launch FahMon through gdb with

Code: Select all

gdb fahmon

Then type run, hit enter and see what happens. If it crashes again, can you send me the output from gdb as this will generally contain the info about what caused the crash.

Appreciate the help but it was my firewall blocking ports, I didn't think of this because it had been running for the past few days without any errors and I thought I set up the rules on both sides properly, obviously not! Thanks again.

[Oak37]

It turns out it wasn't the firewall. I compiled it again and It's repeating the same behaviour and I've tried numerous firewall options including disabling firewalls on both sides. I did run gdb though although now FahMon is hanging rather than crashing. The 'Downloading New Projects' window appears but then hangs. I ran this numerous times and got two different outputs from gdb. The first one here is when I manually terminated the program:

The second one is different but I didn't do anything differently:

EDIT: I've discovered the problem only occurs when I try to add the GPU client to be monitored, I'm able to monitor the CPU client with no problems.

I'm hanging on Archlinux (pure x86_64) with 1 SMP client and 1 remote CPU client (cifs mounted to ~/mnt)

[Trivolve]

Hi, i was just wondering whether you could add a feature in.

I'm monitoring my FAH clients on a few computers over my wireless network, and sometimes they are off but i want to know their progress, so perhaps instead of the "Something is wrong with this client. Please check the messages (FahMon->Show/Hide Messages Window)." message, you could post the latest version of FAHlog.txt that FAHMON had accessed below that, so that i can track the last update on the computer even if it is off at the current moment. Thanks.

[JWhy]

Hello,

I'm wondering if there is a way to select a specific language for FAHMon GUI instead of the default one (apparently based on the OS's regional options) ?

My locale is french (fr_FR) but I would like to display english messages
Is there a proper way to do it (other than deleting my /fr_FR folder, duplicating the /en_GB folder and then renaming it to fr_FR ...which seems to work just fine. ) ?

Thanks,

JY.
edit: Of course, I do not want to change my regional options

[uncle_fungus]

In short the answer is no, not the way I'm implementing the language settings. However I know it is possible to allow language selection in wxWidgets apps, so I'll look into it.

[JWhy]

OK, thanks UF.

Here's what I did :
1/ Quit Fahmon
2/ Rename /fr_FR to /fr_FR.original
3/ Duplicate /en_GB
4/ Rename this copy to /fr_FR and rename the file en_GB.po to fr_FR.po
5/ Start Fahmon

and voilà, it's in English

JY.

Here's what I did :
1/ Quit Fahmon
2/ Rename /fr_FR to /fr_FR.original
3/ Duplicate /en_GB
4/ Rename this copy to /fr_FR and rename the file en_GB.po to fr_FR.po
5/ Start Fahmon

Hi JY!

You don't need to make a new fr_FR out of en_GB. If FahMon doesn't find the language set up in the OS, it automatically uses English. So steps 1, 2, and 5 are enough.

Gerby

[JWhy]

Ah , I didn't know that.
Thanks for the tip

JY.

[uncle_fungus]

It depends whether you want British English or US English. The default is US, which you'll get with Gerby19's method.

[Russ_64]

Any chance that that OSX version will work on the new iPhone 3G? or maybe a port sometime in future?

[uncle_fungus]

Not in the near future no, since the wxWidgets toolkit doesn't currently support the iPhone, and I'm not sure that the current FahMon interface is suited for an iPhone.
