Mac OS X requires root privileges to bind port 80, but if you start eclipse or Tomcat with root, the various files created by the startup are root and cannot be deleted by ordinary users.To do this, we can do the network layer port forwarding through the pfctl, so that the connection to the native 80 port of the request, are forwarded to 9090 port; (Note that Mac OS uses 80 ports for network file sharing, to shut down first)Modify/etc/pf.conf, use sud
Start Tomcat Server error:
Several ports (8005, 8080, 8009) required by Tomcat v5.5 Server at localhost are. The server may already is running in another process, or a system process may is using the port. To start this server you'll need to stop the other process or change the port number (s).
Cause: Port 8005, 8080, 8009 are occupied. It is possible that eclipse was turned off with Tomcat turned on, or that eclipse was shut down abnormally, causing

To debug the program, the native installs IIS and Apache, cannot use 80 ports at the same time, now gives the workaround:
Method One:
IIS5, multi-IP coexistence, IIS for 192.168.0.1,apache for 192.168.0.2 original address
C:\Inetpub\Adminscripts
cscript adsutil.vbs set w3svc/disablesocketpooling true
The command feedback follows DisableSocketPooling: (BOOLEAN) True
Restart IIS
Inetpub\adminscripts>cscript adsutil.vbs set w3svc/disablesocketpool
A single process listens on multiple ports
A single process creates multiple socket bindings for different ports, TCP, and UDP are all rows
multiple processes listening on the same port (multiple processes listen on same port)
The way you create a subprocess by fork can be done in other cases.
When the connection arrives, the child process, parent process can accept, this is the famous "surprise group"

If the switch port of a vswitch is "err-disabled", it is likely that the workstation Nic device is not properly installed, then you can reinstall the NIC or update its driver.
During normal work, the failure of workstations to access the Internet is generally caused by the switch port. Currently, many technical forums have provided some solutions to switch ports, these methods provide us with ideas and methods for efficient network management.
However
For how to disable useless ports in win2000, I mentioned this in my previous posts and Shared Folder Security I wrote yesterday.Here I am writing security knowledge basics for your reference:Each Service corresponds to the corresponding port. For example, the WWW Service port of zookeeper is 80, smtp is 25, ftp is 21, and the service is enabled by default in win2000 installation. It is unnecessary for individual users to disable the port, that is, to

Use finecms to bind a domain name to a multi-site master site: 1.1.1.1: 803 create a new website to inherit from the master site, and bind the domain name to: 1.1.1.1: 804. The problem is: whether access is 803 or 804, the content displayed on the front-end is displayed on the main site. How can this problem be solved? The GA intranet IP address is insufficient. only phpcmsfinecms ports can be used.
