ngrinder3.3对hosts内主机名配置要求？

[ypspace]

目前将agent部署在AIX上，启动成功，但是执行测试时报错，无法启动执行。
已下是错误日志：

本机操作系统为AIX，虚地址为192.168.1.6，实地址为192.168.1.26
hosts文件如下：
127.0.0.1       loopback localhost
192.168.1.26    test-TSC2

[junoyoon]

We haven't tested it with AIX.

I googled the error. The reason seems like that underlying DNSJava library searches the DNS sever in the /etc/resolv.conf and.. AIX doesn't have it.

Please see what you have in the /etc/resolv.conf and add the following configuration in your  /etc/resolv.conf

search com
nameserver your_dns_servrer_IP

[junoyoon]

The another way to configure this is that

1. open ${NGRINDER_AGENT_HOME}/agent.conf file
2. put the following line.

agent.java_opt=-Ddns.server=your_dns_ip -Ddns.search=com

3. restart the agent.

[ypspace]

添加agent.java_opt=dns.server=192.168.1.101 dns.search=com
启动不成功，报错：

[ypspace]

由于测试在内网中进行，脚本使用实际IP地址，不需要DNS解析，如何在启动时不使用DNS模式，如何设置？

[junoyoon]

Sorry. It should be

agent.java_opt=-Ddns.server=your_dns_ip -Ddns.search=com

I omited "-D".

[Kingo]

Why can't set the hosts in /etc/hosts?

[Mavlarn]

Because it is not convenient to set all hosts files manually on all agents.
