The desktop version is Mates.

MUlticast Drop Issue On Ubuntu 16.04

Hello Team, We have installed an Ubuntu 16.04 LTS on our system to receive multicast packets but we are facing issue with IGMP connection.

Can you please let us know is there any specific settings to be done to keep th

Diagnosing networking and boot drive issues, likely due to faulty hardware

Linux ioctl

Is this the right place to ask for help with ioctl? I am looking for someone to discuss applications of ioctl. I feel pretty confident about theory of ioctl, no need to revisit that. I have managed to apply / use ioctl in i2c and GPIO applications. I have few issues with making SPI play.

Bizarre rogue PHP script

I found a bizarre rogue PHP script on our website. It was named hbindy.php, was 1953 bytes of ASCII gibberish. I don't see how it could be executed. We keep records of all PHP scripts executed and all files HTTP-ly accessed, and it doesn't show up in any of them. There's no reference to it in any of our legitimate scripts or pages. I don't post it here in case it could cause trouble. A search on that name shows nothing, nor do searches on strings extracted from it. We don't know that we've bee

Repeating xhci_hcd error in syslog after wireless keyboard update

Yesterday while browsing around the Software Center in my Xubuntu 18.04, in the 'Updates' tab I came across one available for my new, weeks-old Logitech wireless keyboard and mouse, named "Logitech Unifying Reciever". I shrugged and installed it. Everything seemed fine at first, but soon started to notice my mouse would stutter on screen, almost imperceptibly at first but it almost seems laggy every now and then. So I glimpsed into my syslog and seen this endlessly filling it: Dec 14 00:17:03
