Solved Failure on windows SBC install

[AWS2P]

Hi
I'm moving a pbx to cloud and I'm converting in SBC the previous pbx pc running W10
Install and restore on cloud pbx is OK, but now the SBC install is stuck on the step displaying the message on screen copy



FQDN is resolving on new public IP adress without problem from SBC computer.
Also 3Cx console is available from https FQDN
Provisioning URL and authentication KEY ID have been copy/pasted so no way to typo error

So what can i do to get an SBC ending properly his install and working fine ?

 

[AWS2P]

I just found some weird thing nslookup is giving the right Public IP against FQDN, but if I ping using FQDN or IP none are answering.

Have you uninstall 3cx from the pc ?

Check the windows\system32\drivers\etc host file

Do you have an fqdn dns configure somewhere else, which may be pointing to the internal IP address of the old 3xx server

 

[AWS2P]

Just gone in aws firewall and added an ICMP rule and now ping is answering from both IP and FQDN

Have you uninstall 3cx from the pc ?

Yes first step and done a PC reboot before SBC install tries

Do you have an fqdn dns configure somewhere else, which may be pointing to the internal IP address of the old 3xx server

No DNS on that location, only ISP box combining router and firewall, but in NIC dns setting is on google 8.8.8.8

Check host file, as above

If you have a fixed IP address, you could add the fqdn to the host file as a temp solution to get the system up and running

 

[AWS2P]

got something in host file fqdn is linked to 127.0.0.1 but after deletion of that entry I cant save the modified file

 

[Saqqara]

You need to change the permissions / security of the file,

Lines starting with # are remarks , and not activate

Ok thanks Saqqara, right on target, i got hosts file with entry deleted and file saved, now SBC install is ended and SBC is seen connected to 3CX

 

[Saqqara]

Glad to see it is how working,

Now the next step reconfigure the phones to use the sbc server

 

[AWS2P]

exactly , and i do this all remotely so it's really painfull to reprovision the phones manually

 

[AWS2P]

Got everything working and reprovisionned even if it was not a pleasure to access manually in each phone GUI to factory reset them, but it ended fine so the result is good.

Thanks for all help Saqqara
