Also, last I checked, Secure Shell relies on an NaCl plugin incompatible with the Samsung ARM Chromebook.
There's an enable "Portable Native Client" (PNaCl) in about:flags (dev. branch, at least), but I have little idea if this would fix the problem. This kind of troubleshooting is OK for power users, but seems at odds with the type of users ChromeOS wants to attract. Still love this machine, though.
