Mystery solved! That matches perfectly:

Those are you — manually SSHing from behoserver to the router! The "preauth" close just means you connected, got a password prompt (or lacked keys at that point), and disconnected before authenticating. The history shows you were also cd .ssh around the same time, likely setting up key-based access.

The later entries show you successfully got keys working and connected to a bunch of machines:

Jun 01 08:01:19 → ssh 10.0.23.23 (behopc)

Jun 01 08:01:23 → ssh 10.0.23.22 (behotv)

Jun 01 08:01:33 → cd .ssh

Jun 01 08:01:52 → ssh 10.0.23.2 (router)

Jun 01 08:02:01 → ssh 10.0.23.2 (router - preauth close)

Jun 01 08:04:44 → cd .ssh

Jun 01 08:08:01 → cd .ssh

Jun 01 08:16:00 → cd .ssh

Jun 01 19:30:32 → cd .ssh

Verdict: 🟢 Nothing suspicious. Just you fiddling with SSH keys between machines — probably setting up the passwordless sudo access documented in the network skill. Your .bash_history is tiny (Sep 2025 — likely from the old shell before you switched to zsh/oh-my-zsh), and the real trail lives in .zsh_history.
