Hi

As you may or may not know, I host the FGCom server free of charge, and currently I've had to take it down to free up space for my paid clients.

I hope to be able to move it to a different server but for now I have to take it down.

I hope you understand. If you have any questions email me tgreer (funny at symbol) tsone (big dot) info

That is unfortunate, I hope there can be an alternative host found soon. Thanks for hosting it while you could, is much appreciated by the community.

Guess maybe it is time to revisit work on my fgcom alternative I had prototyped previously. It showed some promise, and doesn't require a singular central server for voice comms, but I got busy and had to put it on hold at the time.

cheers!

Luckily we already have a backup server courtesy of Charles (cbz-026) running on mpserver13. I'll see if I can get the DNS updated.

Hello,

on mpserver13, I have setup an Asterisk server to manage my own telephony over IP with friends and family and I setup a small configuration for FGCom. I do not know neither if the server will fit the needs nor if it will be powerfull enough, but I hope it will be useful and will be useable as a backup server for FGCom, so I do not mind using it for that purpose.
If you try to connect to some frequencies and you get a rejected message, just tell me, I will add new frequencies to my small configuration file and reload the dialplan.

Regards,

Charles

Hello,

sometimes, it may happens that the server suddenly hangs (Asterisk dies). For the moment, I do not know why but if your connection to the server fails (server not responding), do not hesitate to tell me. I try to be aware as soon as possible when such problems occur. Maybe I have to move to a more powerful server ?

Best regards,

Charles

I keep working on the server configuration but it still sometimes hangs up. I do not know if it is because the server is not powerful enough but before moving to a more powerful one, I try to set fine tuning on some server options.
I have just setup the following options :

- iaxthreadcount = 200
- iaxmaxthreadcount = 1000

in the iax.conf file.

hoping that it will prevent the server to die.

If any of you have suggestions, all are welcome. I am not an Asterisk guru but I make my day with it.

Best regards,

Charles

May I support in this effort? I have 10 TByte traffic per month included. The machine is a Quad Core 2.2 GHz each core and 8 GB RAM (DDR3).

Hi Quix0r,

are you able to setup an FGCom server ? I have some issues with mine and if you want, I can send you my configuration file for Asterisk and help you for setup.

Your server is more powerful than mine and your traffic bandwith is quite impressive. So if you have the possibility to setup an FGCom server, that will be great !

Regards,

Charles

PS : currently, the FGCom server is down for an unknown duration :(

I wonder how much traffic you got with a fgcom server? And how "secure" is it configured? Can anyone on this planet (even without an installed fgfs instance) use that server for any purpose?

Hi,

I have setup an Asterisk Server for my own telephony over IP between family and friends, with gateways to land lines and mobile phones, and it works quite well. I just added up a "fgcom.conf" file for use with FGCom.
The bandwidth heavily depends on the number of connected peers and on the codecs you use. Usually, the first codec used is the GSM one which has a bandwidth of about 13 kb/s for one peer. There are other codecs that can be used like G711 (uLaw for north america and aLaw for Europe).
Other codecs like G723 are of better quality and less bandwidth consuming but they are not free so I do not use them. Somehow, I am not a specialist of codecs in audio encoding.
With your bandwidth and computer power, I guess that you can have several peers connected at the same time. On my server, I usually saw about 15 ~ 20 peers connected with no relevant bandwidth issues.
About security, I sometimes see brute force attacks from servers which try to register a SIP account (they try to register with account "0000", then "0001", and so on until "9999"). Somehow, if you do not have any SIP accounts but only IAX2 accounts, there is no problems about such attacks that you can ignore. I have SIP accounts on my server but those attacks never succeeded (for the moment).

I hope this gives you some clues to setup an FGCom server. Feel free to ask me any questions if you want some help.

Regards,

Charles

I really like to help, but I better setup accounts for every FGFS user + a echo-account (guest:guest maybe) for testing purposes. I don't like the idea that all people all over the world can do IP phoning over my server. Then my server would be quickly on its limits which is bad for all of us.

I will think more clearly in the next weeks about it. Merci for your help. :)

In the Wiki is a default configuration. Does this mean, every user can use guest:guest to login into asterisk and use my fgcom server? If so, this is what I really don't want. The echo-box will be fine for guest:guest but not the whole fgcom service.

And please sent me your fgcom config file, then I can take a look on it. My email: roland__REMOVE_THIS__.mxchange__AND_THIS_TOO__.org

Re: FGCom Server Down 30th January 2011

Postby cbz-026 » Tue May 17, 2011 11:21 am

Hello,

the FGCom server (mpserver13) is currently down. I do not know if I am going to set it up again due to the fact that it has limited resources and sometimes, the asterisk process is stopped because it seems that requested resources overhead allocated ones. I use a dedicated virtual server with limited resources (and with 2 MB bandwidth).
Maybe, I could set up a real dedicated server (with higher bandwidth) but it is more expensive to hire. I would like to keep using my current solution for my own personal telephony over IP by priority. If adding functionalities like a FGCom dialplan overheads the allocated resources, so my server would sometimes hang up and my telephony over IP would be broken. This is a behaviour I would like to avoid.
I could also call for donation (if some are ready for that !) to hire a more powerful dedicated server with more bandwidth but I am wondering how much people will be ready to pay to get such server ?
I am going to try to look at a better solution to reactivate the server as soon as it is possible. But for the moment, it is down, I am very sorry for that inconvenience, and I apologize in advance.

How much money does it take per month to set up a dedicated server?
And if you manage to restore the old system, is that free or would you have to pay for that too?

Thanks for your work so far!

I have space and bandwidth if required...


ps: I've always offered this for free, but donations would be graciously accepted.
