Re: ssh vulnerable
Hi checked a little bit some other sources also and it seem that disabling the -etm macs is also advisable. Same as for ciphers. get the current list of macs: sshd -T | grep -i 'mac' remove the ones with -etm in the name and add a line at the end to /etc/sshd/config. sample for centos 7: macs umac-6...

New poll!
Which distro should we focus on for eFa?
in the light of redhats announcement to close the source . Wouldn`t it make sense now to focus on Debian or Ubuntu LTS ?

Re: Next Major Release OS Version Survey 2020
Hi
based on the current decision of Redhat to lock down their repositories i voted for Debian.
CentOS is and was not bad. But with this mindset you can no longer trust redhat. Or should we say IBM ?

Re: Next Major Release OS Version Survey 2020
Ubuntu might have the same attitude next week and CentOS Stream is like gambling .
So natural choice is Debian. One the other side why isnt devuan on the list ?

Re: Centos 8 roadmap
Not sure if Debian is the right choice.
But im also really dissapointed about this behaviour.
Lets see if the wave of feedback will change the mind of CentOS people.

Hi there is no direct upgrade from CentOS 7 to CentOS8. So you need to save the config and your customization and migrate to a new VM. at least not an official one. https://wiki.centos.org/FAQ/CentOS8#Is_there_a_way_to_upgrade_CentOS-7_to_CentOS-8.3F_How_about_leapp.3F But you can make a snapshot of...
