When I turn it on https://www.kernel.org/doc/html/latest/networking/ip-sysctl.html I guess it's IP_ Dynaddr - Boolean. If set non-zero, enables support for dynamic addresses. If set to a non-zero value larger than 1, a kernel log message will be printed when dynamic address rewriting occurs.Default : 0. Should it be set to 1 to send packets disguised as IP? But when I use vi IP_ dynaddr To modify and save the prompt: "IP"_ dynaddr" E212: Can't open file for writing“. So I used Chmod 777 ip_ dynaddr authority, display error: Chmod: changing permissions of 'IP_ dynaddr': Operation not permitted. I use chaddr - i ip_dynaddr command to removes attributes and displays an error: chattr: Inappropriate ioctl for device while reading flags on ip_dynaddr. How to set dynaddr?
