Hi Jordon Thanks for taking the time to report this bug in Ubuntu.
By just uncommenting that one line you will create a proxy loop - the gateway.example.com needs to be setup with a "ProxyCommand None" entry as well. So its nothing todo with a non-existent host - its just a misconfiguration IMHO. I was not able to take down a 12.04 server - I quickly got an out-of- memory error and the ssh command terminated. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1025418 Title: Using ProxyCommand w/a non-existant host results in infinite spawns.
