Why VOS3000 Server getting restarted daily auto, Know easy Solution
Hello,
Table of Contents
if you are using VOS3000 2.1.8.0 or 2.1.8.05 sometime VOS3000 server went down/restart/reboot auto daily in a fixed time and VOS3000 server starts but vos3000 softswitch shows offline or softswitch stays offline or red on softswich.
reason that happen in VOS3000 installation script have one cronjob where it have a command line to reboot/restart the server everyday, so according to timezone the vos3000 server reboot everyday sametime and when it starts sometime in cloud server or small vps or low resource server have problem for auto start the mbx3000 which is Softswitch module in VOS3000, so after server restart and come back online mbx3000 stays stopped and shows softswitch offline in VOS3000 client software you will see red in mbx3000 status icon where it suppose to be green, in that case need to login to ssh and start the mbx3000 manually by command line “service mbx3000d restart” or “service mbx3000d start” VOS3000 Server getting restarted
but the real solution is stop that cronjob, so the server will not get rebooted everyday at sametime. for centos7 or centos6 server command for cronjob edit “crontab -e” then it will open a linux editor and remove the command line and save. VOS3000 Server getting restarted
Also you can add auto cronjob if incase mbx3000 goes offline the cronjob will check automatically and start the mbx3000 in server, for that you will need a custom cronjob whcih will check the status of mbx3000/softswitch and will start it auto if that is offline or down. VOS3000 Server getting restarted
if you need more help or details for vos3000 then contact in whatsapp: +8801911119966 (only whatsapp text)
VOS3000 latest versions like 21805 or 21907 work mainly on Centos7, so you will need to use Centos7 as OS for VOS3000 2.1.8.05 or 2.1.9.07 Versions. Any Centos7 is ok but will need accurate kernel to work the emp, else emp will fail sometime.
any Centos7 is ok but if you still ask me then you can use this ISO which is small and easy to install

VOS3000 API (2.1.9.07) Connection, Common issues, VOS3000 API easy Guide
Hello,
Table of Contents
in earlier VOS3000 versions for VOS3000 API Connectivity we needed few extra modules, like VOS3000 3rd Party (rpm) or VOS3000 Web External (rpm) to be installed at the VOS3000 server but in VOS3000 2.1.9.07 those are auto builtin with the server and no need any extra rpm file to be installed, for example 2.1.6.00 version had extra files named: vos3000-webexternal-2.1.6-00.i586.rpm and vos3000-webthirdparty-2.1.6-00.i586.rpm to be installed in VOS3000 2.1.6.00 server, so APi module worked with those api calls, but now no need to install anything like that, VOS3000 2.1.9.07 version have all builtin, still many people fail to connect the API. Here is some common issues i want to mention:
in VOS3000 API manual (2.1.9.07) you will see everywhere it mentioned http://ip:8080/external/server – but where is actually the VOS3000 2.1.9.07 by default http port is 9090, so correct URL will be http://ip:9090/external/server , many people get confusion on the URL and fail to work on it
VOS3000 2.1.9.07 version they developed a Test interface from where you can see if the VOS3000 is working or not with the API calls, what are the return codes coming, but you have to allow your local ip (computer ip) in the VOS3000 web access control to make that link workable and only then you can test…
this is VOS3000 Web External API Call Test Panel, you Can test api from here if they are working well with server or not, you have to allow VOS server ip also your computer ip to access this ip….
This is the place where you have to allow the ips, to activate both real api call and test call as well, /external/test/ – this place for test the API CALL. now many people had issue with ipv4 and ipv6, when they try with localhost, 127.0.0.1 – the server try with ipv6 to connect with the VOS3000, so i have also added 0:0:0:0:0:0:0:1 – which represent ipv6, so if you in case have issue to connect with ipv4 then this will work too.
This you will see after you test the API Calls, the response will shown with retCode (return code), and you will see if thats worked with your VOS3000 server or not, you will able to see changes in your VOS3000 main server.
here in from SSH i am trying to get real data for API call to get all customers name, the result also came with all customers name, you can see names are showing after return code.
Here you can see exact those accounts are in my server which the API got from my server in SSH.
So overall VOS3000 2.1.9.07 Have most easiest way to connect the API, you can develop your own VOS3000 complete web management solution if you want also you can use any billing software if you needed. The VOS3000 api manual is in chinese, so many people get confusion but this is very easy and all things are builtin, so no need anything extra or any extra pain.
if you need anymore help for VOS3000 API settings, manual, api connection issues, API not working, how to connect api easily or anything you need to know about VOS3000 API for 2.1.9.07 or other version VOS3000 API related things or manuals then knock me in whatsapp: +8801911119966 (Whatsapp only)
