我已经停止使用CentOS运行上下文代理实例的虚拟机。在使用enabler重新启动系统时,后者会出现致命错误。见以下日志:
# contextBroker

[root@VM-20-14-centos lighthouse]# sudo systemctl restart vsftpd
Job for vsftpd.service failed because the control process exited with error code. See "systemctl status vsftpd.service" and "journalctl -xe" for details.
[root@VM-20-14-centos lighthouse]# sudo netstat -antup | grep ftp
我正在使用Ubuntu16.04,但我相信我的问题适用于许多发行版,如Debian、CentOS和Red。
netstat -l的手册是:
Show only listening sockets. (These are omitted by default.)
netstat -a是:
Show both listening and non-listening sockets. With the --
interfaces option, show interfaces that are not up
netstat -a的输出是否包括nestat -l的输出?在主页上似乎是这样的,但
