rackspace ports

When we conduct system security protection, we need to prevent Trojans, and there is a network connection to the Trojan. We detect the data port and process mode to prevent Trojans. We use VC ++ to detect Data ports and processes. For more information, see code implementation and annotations. # Include

Find the service name with the specified port and protocol if you want to find a network service, it is best to know which port the service is running on TCP or UDP protocol. If you know the port that the Network service uses, you can call the Getservbyport () function in the socket library to get the name of the service.Technical Point decomposition:1, define the Find_service_name () function, note the code indentation in the function2, Getservbyport (Port,port_type), through the port lookup se

same client accesses App1 and then accesses APP2, it will find that the APP1 session is missing.When the client accesses App1, Domain01 retains a cookie named Jsessionid on the client, records the DOMAIN01 information, jsessionid the default value of WebLogic Cookie-name, When the same client accesses APP2, the Jsessionid value in the client cookie is Domain02 refreshed, and if you continue to access App1 in the previously opened IE, the session is lost (Jsessionid has been Domain02 refreshed!)

Redis is only locally accessed by default after Ubuntu installation and requires additional IP access we need to modify the Redis configuration file1. Dpkg-l Redis-serverThis command we can see the Redis installed files in those directories2. We then modify the configuration filesudo vim/etc/redis/redis.confThis is what I changed, by default it's 127.0.0.1.Here I change is 0.0.0.0 that is the arbitrary IP can be accessed, of course, can also configure multiple IP access, multiple IPs separated b

The 1.Netstat command is used to display various network-related information such as network connections, routing tables, Interface states (Interface Statistics), masquerade connections, multicast members (multicast memberships), and so on.2.lsof (list open files) is a tool that lists open files for the current system.The 3.kill command ends a process by sending a specified signal to the process.So, there are two ways to do this:Lsof-i: 8001Netstat-apn|grep 8001Release the port on the PID corres

Our firewall default rules are as follows:If the firewall releases the port but still cannot access it, it may be because the rule is added with the IPTABLES-A option, so that the added rule is arranged after the 6th rule, although the service Iptables status shows that the port is released, but in fact, As a result of rule sixth, the new addition does not work.Instead, use iptables-i to insert the rule, and before you add the rule 6th, you are ready to take effect.The Linux firewall has release

The Oracle listener on the server has been started.Lsnrctl Status View Listener stateLsnrctl Start Oracle Listener3. The error message that the client gets is usually: Ora-12170:tns: Connection timed outAt this point, we can basically be sure that the server is not open 1521 port (assuming you use the default settings)Workaround:1.
