I need to be able to tell which process a given window was created by. (Window ID=>Process ID)
Apparently, X servers don't know which process a client is, they just get a socket (b/c of X's network transparency). It has been suggested that I could run a program like netstat on the client machine(which in my case is the same machine running the server) to get a list of which sockets belong to which processes. Then, I need to get the ID of the foreign socket (socket ID on client end) from which a window was created. What would work well is if the socket ID and the client/window ID could be written to STDOUT or STDIN when the window is created. Then I can have a script read the server's STDOUT or STDIN and compare it to the list of socket IDs and process IDs from netstat on the client machine (which for my purposes is on the same machine as the server). MY PROBLEM: I don't know how to get XFree86 to write the socket ID and client ID when a window is created! Today, I was looking at the XFree86(4.3.0) source code for the first time and trying some different hacks to get the info I wanted to print. In xc/programs/Xserver/dix/dispatch.c, I found ProcCreateWindow and the ClientPtr structure. I was able to get X to print client->index and client->OsPrivate->fd when a new window was created. Which is what I want, except that the client index that is printed is always 2 and the socket ID is always 13. 13 is the ID of the socket that X listens on and I think 2 is the server client? What am I doing wrong? How can I print the Window ID and foreign/from socket ID of a client when a window is created? :) thanx PS: I'm thinking of making a sourceforge project to publish the XFree86 modification and some associated scripts so that others will be able to see which process created which window. How does the project name XTracer sound? __________________________________ Do you Yahoo!? Yahoo! Finance Tax Center - File online.
