OK so we have been running a dongle server on Linux (debian VM) for a couple of years, rarely problems with maybe a good 8-12 dongles.
Mid last year, we seem to lose alot of the dongles, as in they were not visible from the Windows clients (VMs). After a reboot of the Linux system all was well.
But the last couple of months, things have been getting slowly worst. Currently problems:
1. We don't see all the dongles, maybe 4 out of a good 8.
2. I might restart the system and power off one of the USB hubs and we see maybe 6? But two days later some are not visible again.
I upgraded the Windows client, no difference.
3. It seems to get confused what dongle is which one (within brands). We have five (5) of one brand and it doesn't seem to know which one is which, especially if i have to move them. Do I need to power down, remove, power up, then add them one at a time? Or is this just a flow on effect of our bigger problem?
So, is there a log which might show errors? I'm guessing there is. (sorry more a wintel person)
Sorry what is the best way to upgrade the Linux server/daemon.
