I guess you could say Gandalf's application is seeing TCP segments and saying "you shall not pass".

Ah, I see! I will edit my answer so it's a bit clearer for others facing the same problem who find this. Thank you for explaining :)

That's why I said "IP address then goes on the bridge, not on the physical interface" :)

comment A tool to get disk activity statistics from strace?
This should be calculable using a script of the usual Linux text processing tools (awk, sed, etc).

Do you have both the network service and NetworkManager running? If so, stop and disable NetworkManager or uninstall it altogether.

Does whoami really return a blank line? Usually that should be your username. Also you only showed output from one system.

comment Remote SCP & SSFTP access to linux server denied
How do you think you disabled root logins? Your config contains PermitRootLogin yes. As passwords work, this sounds like a problem with your keys. Can we see whoami; ls -alZ ~/.ssh on client and server?

comment Remote SCP & SSFTP access to linux server denied
Post your config. egrep -v "^#|^$" /etc/ssh/sshd_config should get ssh. Also show your firewall. Don't forget to chmod 700 .ssh and chmod 600 .ssh/authorized_keys, plus restorecon -R .ssh if you're using SELinux.

comment How to capture ack or syn packets by Tcpdump?
Personally I would not do this. I'd capture all packets, then filter on SYN and ACK flags later. If you're troubleshooting TCP, you almost always want to see a whole conversation, not just a handshake or ACK. If you're not interested in the actual data payload, you can limit packet size with tcpdump -s SIZE. The TCP header can be a variable length, so capturing -s 128 will probably get all possible headers and maybe a little bit of data.
