The telnet service is very powerful. This function is used by many administrators. However, due to its security and restrictions, friends who use it may also feel uneasy. Here we will explain the mutual telnet between systems and some security issues. Telnet between host Windows XP and Virtual Machine Linux First, the host machine is Winxp and the ip address is 1

open_basedir, that is, disable file operations outside the directory. This protects local files and remote files from attacks, pay attention to the prevention of attacks on Session files and uploaded files. The third is to set safe-made to the enabled state to standardize the commands to be executed and prohibit file upload, it can effectively improve the security factor of PHP websites.

at the following code:void printeachwithlen (int* nums,int length) { int i; for (i=0; i) { printf ("", Nums[i]);} }At this point, we can call the Printeachwithlen () function in the main function:int sizeof (nums)/sizeof(int);p Rinteachwithlen (nums,length);Here's a look at the results:Therefore, it is generally necessary to pass the "Length" argument to the function when passing an array/string, because inside the function there is no known "how Long". For example: memcp

voidAdd (user user) {userscache.put (User.getid (), user); } Public voidGetintID) {userscache.get (ID); } }This fragment of code, the Userscache object is thread insecure. Because it is a static global shared object.If there are multiple threads calling the Add method at the same time, it may occur that the user object is overwritten, that is, the ID corresponds to the object inconsistency, which is the most common thing in multithreaded programming.Therefore, you can use the Co

In many cases, you can [always] or [need] use multiple threads. This will bring a better user experience, so that you will not suddenly get stuck when you are operating a function. In the case of. net winform, you can consider using the [asynchronous/auxiliary thread] when the control operations are not involved and the data volume is large 〕. The asynchronous/multithreading method generally considers the creation of the delegate, and then BeginInvoke, or directly implements the Thread operation
