The client is not sticky and may be stuck on the service sideFirst you need to master the principle of a Socket transceiver messageThe data that the application sees is a wh

In Linux, if you have write access to a directory, then we can create a delete file in this directory.Now we're going to create a directory where we can create files, but other users can't delete the file.A special permission is used here: sticky bitsThere are three special permissions in Linux, namely:SetUID = 4: Permissions set on the ownerSetGID = 2: Permissions set in the owning groupSticky bit = 1: Set in other people's position (denoted by T)Fir

Originally I intend to open a separate chapter, specifically to explain the sticky bag and broken bag, but I think this thing I am doing is a headache, but for others may not be so important, so write it here.So what is a sticky bag or a broken bag?

SUID, SGID, and Sticky attributes of the file SUID attributesThe SUID attribute is generally used on an executable file. When a user executes the file, the user temporarily has the permission of the owner of the executable file. When you use the "ls-l" or "ll" command to browse a file, if the third digit of the executable file owner permission is a lowercase "s ", it indicates that the execution file has the SUID attribute. For example, the/usr/bin/pa

At the same time, the file also has a group number, indicating the group to which the file belongs, generally the group to which the file owner belongs. If it is an executable file, the file generally only has the permission of the user who calls the file, while setuid and setgid can change this setting. Setuid: set to grant the file owner permissions during execution
