我有一个有点像这样的服务器:
class Server {
private WorkingThing worker;
public void init() {
runInNewThread({
// this will take about a minute
worker = new WorkingThing();
});
}
public Response handleRequest(Request req) {
if (worker == null
我已经配置了ActiveMQ主服务器和从服务器。
如果主服务器发生故障,则从服务器设置为活动服务器,但无法从主服务器获得先前的消息。
主配置(broker.xml):
<connectors>
<!-- Connector used to be announced through cluster connections and notifications -->
<connector name="artemis">tcp://192.168.2.200:61616</connector>
我的服务器(Ubuntu18.04)在Postfix上收到了大量垃圾邮件请求。Fail2ban正在工作,但垃圾邮件发送者一直在改变IP的最后一部分,并且没有被禁止。例如,
2021-10-09 09:40:01,260 fail2ban.filter [790]: INFO [postfix-sasl] Found 212.70.149.88 - 2021-10-09 09:40:01
