EMP Start Failed in VOS3000 Server SSH, How to solve ?

June 7, 2019June 12, 2019 king

Hello All,

# service empd start
Starting kunshi emp service: [FAILED]

Many of you face issue EMP Start Failed after giving the command for EMP, There are many reason, I will Describe now one major issue. VOS3000 Emp do not support all kernel versions of Linux. Mostly used OS for VOS3000 is CentOS, Centos 5.11 is no more supported anymore by centos, so its difficult to get it from any datacenter but possible. Need to Fix Repo file in that case. Also Centos 6.10 or Centos 7 also not supported many versions of VOS3000. Mainly emp not start due to kernel issue. without emp start you can not start MBX. In that case you have to downgrade Kernel to supported kernel or need to upgrade kernel to supported one. I am sharing emp supported kernel list here in attached file. So you can upgrade and downgrade easily.

For Upgrade or downgrade Kernel version you can search in google, there are many easy manual for that.

emp supported kernel list

Some important commands you need to know for kernel issue with vos3000.

You need to use standard rpm command to list installed software. Type the following command at shell prompt:


$ rpm -qa kernel
Output: kernel-2.6.18-4.1.15.el5 kernel-2.6.18-8.1.14.el5 k ernel-2.6.18-8.1.10.el5

VOS3000 Extended Firewall for Secured Server

May 27, 2019March 10, 2026 king

VOS3000 Extended Firewall for Secured Server

Hello all,

Basically we was the first who developed “Access Code” based firewall. Its actually most simple and easy firewall ever. The reason of this firewall is:

1. Many unwanted people scan ips and try for login in vos client, so for access code now its double layers. Without allowing access code nobody can login vos client. So they need to know both details.

2. Our Firewall block all chinese/russian/hacker ip database. So its completely updated automatically from our ip database.

3. We changed SSH ports as well and without allowing “Access Code” you can’t even login ssh.

4. VOS3000 Extended Firewall rules updated every month, version wise rules are not same, because each version have each type loophole, so need to study and work accordingly. Otherwise firewall will be useless.

5. we do not use any php based web firewall which looks good but actually not work well

6. we use simple rules in iptables and access code based system

7. outlook is not important for firewall the backend rules is most important here
