CTO of XDA Developers.

Linux systems are my specialty. As with any good system administrator, I dabble in networking, storage, virtualization, Android, and more.

LOPSA since 2008

I enjoy spending time with my family, social media, gaming and going backpacking. I have also blogged professionally for MakeUseOf, Lifehacker, and my own personal blog about system adminstration.

comment Why does my ssh timeout vary with network location?
This is a setting on the client endpoint, so although if you are in a hostile environment this might add to the ability for someone to spoof you, it is very highly unlikely to make an impact on the security of the connection. I can't really see this causing extra load, either.

comment Intermittent DNS timeouts, independent of DNS provider
What is your network setup, and do you have any sort of QoS or filtering appliances in place? Firewalls?

comment named Cluster DNS breaking ssh
Drop ssh from the troubleshooting and use dig to do a direct query on your DNS server to see if it is responding properly. Let us know what dig shows for the hostnames. You can use 'dig c0-0 @ip.of.dns.server' to query the server directly.
