It seems ACLs are more and more used by applications running on Debian rsp RaspberryOS. Unfortunately rsync does complain about ACLs with RC23 when files with ACLs are copied with rsync onto a nfs mounted partition. Today I detected it's possible but you have to use an important option when you mount a partition via nfs.

A ssh server is the most common way to access a server which is connected to the internet. Everybody who knows a userid and password or guesses them can access the server if the standard ssh configuration is used. If he succeeds to get root access the server can be compromized by the attacker and will be used as ftp-server, DOS client, mail SPAM sender ... and the owner of the server is liable for any activities of the attacker. That's awkward and can become quite expensive. The following page describeshow to modify the sshd config file to make the ssh server secure and protectagainst any attacks.

I'm bored to struggle with the compile issues of VMware Server on Linux. That's why I decided to use VMplayer. Unfortunately you cannot use multiple physical network cards in a VM - at least if you use the VMwareplayer GUI only. But you can if you add some lines in /etc/vmware/network and add and change some lines in the .vmx file of the Vm.
