Working on debugging a bad sftp connection here, and get puzzled by the log in dialog.
It says "searching for host". I do not know what that means, should it be "resolving host", which indicates a DNS session is in place, or is it "connecting to host" meaning a session is being initiated with target host?
I would love for the message to be something in the line of
1. Resolving host "myhost.test.com"
- DNS SYN request sent to DNS server "10.10.10.4"
- DNS ACK request received from DNS server "10.10.10.4"
- DNS SYN-ACK request sent to DNS server "10.10.10.4"
- DNS resolve request sent using DNS server "10.10.10.4" on UDP port 53, waiting for answer
- DNS resolve response "myhost.test.com": has IP 220.127.116.11
Or if error
- DNS resolve response from server "10.10.10.4": "myhost.test.com": NXDOMAIN
- DNS request timed out (typically 2 sec)
- DNS server rejected connection
2. Connecting to SSH server at "myhost.test.com" on port
- SYN sent
- ACK received
- SYN-ACK received
- Banner received, server identifying itself as running SSH protocol 2.x
Or if error
- connection refused, received RST packet
- connection timed out, received no packets in <timeout> seconds
Challenge response sent
On working connections, this would be very fast and short, and on failing ones it would be very useful...

OK, will consider this.
