Re: 2ssd dual boot windows10 and centos7

You say you ran grub2-mkconfig and it found windows? What did you run and where did you write the output to? Is your system using UEFI or Legacy BIOS?

Re: Automatic Bug Reporting Tool / coredump

Having ABRT enabled on CentOS is pretty pointless as no-one ever looks at the tickets that get raised.

Re: Meltdown and Spectre

Pretty sure that both IBRS and IBPB need microcode support and it's unlikely that a VM will have that and only Intel processors that have had a microcode update will do so.

Re: SSH "party did not proplerly respond ...."

It's the same command and you need to exclude the machine from which you are ssh'ing or it will dump that traffic. So whatever the ip address is of your windows computer, use that in the "not host x.y.z.a" argument. I'm not sure what you mean by "5 minutes behind". It dumps traff...

Re: SSH "party did not proplerly respond ...."

It's a simple test and will help to narrow down where the problem lies. If you are connecting to the system to do this via ssh then you'll need to add "and not host 1.2.3.4" to the tcpdump so it reads "port 2201 and not host ..." where 1.2.3.4 is the ip address that you are conne...

Re: SSH "party did not proplerly respond ...."

Can you get to the server by another method? If you can then run e.g. tcpdump port 2201 -l -n -nn -i any and then go and try to connect to it from outside. If your tcpdump then sees the packets they are making it past the router/firewall and onto your box. If it doesn't then the problem is between y...

Re: Spectre & Meltdown patched but still vulnerable

IBRS requires a microcode update to fix it. Virtual machines are unlikely to have fixed "microcode" available.

Re: PCI compliance when update not available

Does your system match the criteria for allowing the bug to be present? This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. The rest of the description makes it sound unlikely to be easily exploited: Analysis sugge...
