Re: [Openh323gk-users] 2 gnu gatekeepers working as neighbors

Hi Luca,

When you said "Both gatekeepers have a public ip address" I assumed
that each gatekeeper has two NICs, one of which is a public IP.  Or,
at least, the public IP is an address listed by ipconfig.  But from
your .ini file, it seems that the gk's are behind NATs.  Is that correct?
If so, I don't know if what you are trying to do with LRQ/LCF is
supported -- I have not tried this myself, nor have I seen any posts
from others having succeeded.

When you get the 10049 error, is the address printed that for gk1?
If so, it is probably trying to bind to that address, which may be a
bug in the code.  Perhaps Michal can comment on this.  If it's the
address for gk2, you might try adding some debugging statements, so
we know why the system call is being rejected.

Running a gk on a dynamic IP is not a big problem, if your IP changes
only once or twice a year as a result of a network outage.
But if your provider purposely changes your address (some do it
every day) you will have trouble.  Not only will all calls be dropped
when the address changes, but you won't be able to call back right
away, because it will take a while for dynamic DNS to propagate, and
clients to realize the address to which they must register (or send
LRQ).

Regards,

Stewart

Hi stewart,

I've observed LRQ and LCF messages, and they are correct,  the telephony service and the firewall 
are unable.
I see that LCF is correctly read from gk1.
I also keep a check of my gatekeeper.ini file  :-)
The ip 62.101.106.41 that you've tried connect to, is an ip that my provider dynamically assign to 
me.

"I assume that the :0 means that gk1 was trying to connect to
 port 0, which was rejected by the OS"
Well, i have tried to run the 2 getekeepers and the 2 clients in the same local lan, in this case 
all worked fine.(audio and video too)
But i've see that when the gk1 open tcp to the gk2, the log show:
Connect to 192.168.1.82:1721 from 192.168.1.81:0
Where
gk1=192.168.1.81
gk2=192.168.1.82

I read in the manual this words:
"Note to make proxy work, the gatekeeper must have direct connection to both networks of the caller 
and callee."

So,I want to ask you, do you knows if is possible my configuration?

PS: i made my test only with the 2.2.3 version of gnugk, tomorrow i'm trying with 2.0.9 version.

I'm attaching my two gatekeeper.ini files.

Thank you,stewart.
