OK, so my Linux installation on my Xeon 32-core mobo, has somehow gone bad.
Let me explain.
It was (until Sunday 30 Aug), crunching away merrily on some GPU and CPU projects, at my office. And I occasionally remote log into it, to make sure it's OK. I tried to do so on Bank Holiday Monday and it appears to have rebooted at some point before this, and although it was set to "auto-run" BOINC Manager (BM) everytime it boots up, BM was running but it was displaying the "Add a Project" tab.
I rebooted it a couple of times (remotely) and the same thing kept happening.
I was at work today (Wednesday) and the PC was working, but BM was still asking for me to "Add a Project URL".
But BM was not showing ANY projects in the "Projects" tab and no tasks were shown in the "Tasks" tab (of BM).
Doing a quick command line "top" command, I could see that BOINC itself was running (as it was crunching Collatz GPU tasks, tho' it had no CPU tasks).
I took a quick look through the File System and sure enough all the projects are all displayed in the /var/lib/boinc-client directory...so, the files for BM do exist.
And BM is still saying "Disconnected" at the bottom of its window.
I've tried to use the "File > Select computer..." option to select "127.0.0.1" as the host, but still I get "Disconnected".
I've checked again this evening and the PC is still running AND is returning validated Collatz tasks. But I cannot get BM to actually display any Projects or Tasks that are active. And hence I cannot control what projects can accept work and which tasks to actually crunch.
So, there seems to be a "disconnect" between the BOINC program and BM.
I thought of re-installing BM, but I'm running v7.9.3 and the latest version on the BOINC website is 7.4.22 - and there are no instructions to teach this Linux noob, how to re-install BM on a PC running Mint (though there are instruction for installing on a Ubuntu/RedHat/Debian/Fedora OS) - and the Mint Software Manager only has the 7.9.3 version.
So, I'm stuck.
I've switched my Collatz Preferences on their website, so that this Mint host will run dry of work...and I'm tempted to just re-install Linux from scratch - but it's a real pain to do that and I'd rather figure out why BM on this host has lost contact with the BOINC tasks running on it.
If anyone has any pointers, I'd appreciate it.
