Secure Shell Puns

So we had this issue yesterday where secure shell commands were failing from our newly enabled backup system to a downstream application.

I logged in manually using the correct credentials to confirm the keys were fine, but I noticed it was the first time in known hosts, so i typed “yes” to put the entry in and figured that would fix it.

When the problem came back today, I was surprised at first, but then it hit me...

Same ssh -t different server...
