The eskimo.com shell server (old SunOS 4.1.4 machine) is down and will remain that way until tomorrow afternoon. It is stuck in a mode where the kernel is still running and it can be pinged, but no user mode programs get CPU time. This is an old SunOS bug.
We only have one car and my wife has it right now. In the meantime please use one of the other shell servers: shellx.eskimo.com, debian.eskimo.com, ubuntu.eskimo.com, opensuse.eskimo.com, centos7.eskimo.com, scientific.eskimo.com, scientific7.eskimo.com, fedora.eskimo.com, or mint.eskimo.com.
