From the ldd command it looks like the binary is looking in /lib/x86_64-linux-gnu and not /usr/lib/x86_64-linux-gnu where you found the symlink. Try running these and see if you still get the same error: sudo ln -s /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /lib/x86_64-linux-gnu/libcrypto.so.6 sudo ln -s /lib/x86_64-linux-gnu/libssl.so.1.0.0 ...

fail2ban uses iptables to block (assuming you're using the default iptables-multiport "action" in f2b). iptables is just part of Linux, so isn't something you need to install.

The easiest thing to do is remove the default route on host A. That way, it will only be able to contact other hosts on the local LAN, like host B. If you put up a host C on another LAN port, though, host A will be able to talk to it. The next step would be to put host A on a separate network/VLAN, and implement firewall rules to restrict it, though this ...

Restarting services as inetd can do is often not needed as the programs like sshd just start and run in the background, instead of being restarted again and again. If you install some serial ports you might have to install (x)inetd to allow login over a serial line, but I haven't seen any need recently for ...

The question isn't very clear, but my best guess for what you're trying to do is connect to your VirtualBox using ssh. If this is the case, you only need a terminal opened from the computer you're on; to connect to the Ubuntu box, you don't need any "terminals" open. The odds are overwhelmingly good that your Ubuntu box is running sshd, which is the ...

The obvious answer is sometimes the correct one.  You need to write to the cache directory, so you need write permission to the cache directory.  The fact that you're able to do the ls -l demonstrates that you have all the necessary access to the releases directory. You can get the desired access by either adding your user to the nginx group or changing the ...
