Today I had to yank a line from my ~/.ssh/known_hosts file on my jump box here at the office and I noticed that I had a lot of known hosts! I’d be interested to see how many you have.

My work jump box:

bsmith@ops654 [09:06:04 (0.00)] ~/.ssh 
-> wc -l known_hosts 
1155 known_hosts

My desktop:

AGCOM\bsmith@bsmith-laptop [09:07:21 (0.22)] ~/.ssh 
-> wc -l known_hosts 
65 known_hosts
