[PLUG] Close TCP sockets C program.
If kill is used to stop a C program running on Linux that has open sockets, the sockets get orphaned. How can I in the event of a ctrl-c close all sockets owned by the program immediately? Waiting 3-10 seconds for Linux to close the orphaned sockets is too long. ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

I loved Linux Journal and subscribed for many years. I let my subscription go when they went digital as I didn't really have the resources to read it at the time.

But I saved one item: May/June 2000 issue of Maximum Linux, featuring reviews of Corel Linux, Slackware 7.0 and WordPerfect 8.0, plus two CDs containing Storm Linux 2000 and Mandrake 7.0. Corel Linux was my first venture into Linux. For those who are too new to Linux to have heard of it, Corel Corporation, whose main program was CorelDRAW!, by 2000 had added Corel Photopaint, and had acquired Ventura Publisher and the WordPerfect Suite. Their avowed plan was to develop Corel Linux and then have all these programs running on it. Unfortunately, their method was to work with WineHQ to get them all running under Wine. They got as far as CorelDRAW, Photopaint and WordPerfect, but financial difficulties forced them to abandon getting Ventura Publisher working. I was heavily into DTP at the time and I was eager to abandon QuakXPress, PageMaker, and most of all, Windows and MS Office. I eagerly bought Corel Linux and all the Corel programs and installed them on my previous computer, sitting unused. Sadly, Michael Cowpland (head of Corel Corp.) was a genius at user interfaces, and an utter klutz at getting good code. Getting X and Wine to run for more than a couple hours without crashing was usually impossible. Eventually I had to give up and continue my obeisance to the evil empire. If anyone collects old Linux magazines I would be happy to give this copy to someone who would appreciate it. :) ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Re: [PLUG] Permissions over house network
Use NFS instead of Samba for ordinary sharing and replicate the user accounts on the NFS server. That is probably the easiest. Alternatively, you could setup a samba/active domain for central authentication, so that you are the same user everywhere. That would take care of it.

[PLUG] Need to use DBus...
Hello pluggers, I need to use DBus on a Raspberry Pi 3 running Raspbian Stretch to synchronize the reading and writing of a PNG file. One program writes the graphics file, the other program needs to read it. File locking is cumbersome, how do you make sure that the the writer gets a lock before the reader does? If only the writer could talk to the reader before the reader grabs the file. The writer should indicate whether or not the file is ready to be read or maybe the file is still being written. Maybe the camera is still snapping a picture. In theory, if the programs communicate with each other there is no need for file system level locks. Problem, the 2005 Linux Journal article that shows a way to use DBus does not compile. The original dbus is apparently too low level and evidently it is deprecated. Ouch! I'm trying to write a C program to go between the writer and the reader and communicate with both of them concerning the file in question using UNIX sockets, but that seems like overkill and far more involved than I had hoped it would be. Please help! I have twelve days left to address this synchronization issues. I can't replace the 6k lines of C code that comprise the writer of the PNG file in twelve days, it isn't documented at all hardly. ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
Re: [PLUG] Moving from HDD to SSD
That is what I ended up doing, It did well. Actually I copied the old files on the new directory, it asked if I wanted to merge them, I merged them.

Re: [PLUG] Permissions over house network
I believe there's a "force user = " option you can put into your smb.conf that will force all file operations to be performed as that user on the server side.

[PLUG] Permissions over house network
Here's a frustration that I always fix from the command line, but would like to learn how to have it be not necessary, if that's possible. Is there a way to set things up so that when I copy things from one machine in the house to another (using a GUI) that I don't need to change the user to whom the file is assigned on the receiving machine? It's not a difficult fix. sudo chown me:me * works fine.
