Issue/Introduction
The ping to localhost works, but the tibemsadmin tool fails to connect with localhost.
Environment
Linux
Resolution
From EMS 6.3 onwards, EMS supports IPv6. KB 43287 explains why the connection fails. This KB addresses how to workaround on Linux machines to disable the IPv6 in the Linux Kernel and make the tibemsadmin tool connect to localhost.
To resolve the problem:
1. Edit /etc/sysctl.confChange:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
To:
net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
If the above entry is not in /etc/sysctl.conf, then create one.
2. Restart network service: #/sbin/service network restart
3. Restart the EMS server.
4. Connect with the tibemsadmin tool.
