Greetings, Frances B. Webb!

> My ssh config is this, followed by a bunch of hostname aliases:

> Host *
>         ServerAliveInterval 180
> Host solr* jenkins folio*
>         IdentityFile ~/.ssh/aws_id_rsa

> The ServerAliveInterval is something I added when I was trying to debug the
> issue last summer. It didn't work, and I never took it out.

I hope you are aware that all matching operators mutually exclusive?

Do you have any local firewall software installed?
