Great post!

I fully agree that VNC is vastly superior in speed alone to the full blown X
of our old Sun/Linux (Dot Com startup - dial up ISP administration) days,
with all it's snafus (ever had your X session
highjacked<http://www.cas.mcmaster.ca/wiki/index.php/The_Mitnick_attack>by
the Support staff (you managed)?  No? I have..... [very funny you
guys])...

However, our concept of speed cannot be considered without also,
considering, in a non-linear way, security?  We assume that you architect
OSI security protection (VLAN exclusion or strict network switch port ACL
controls) since VNC password exchange can easily be
snooped<http://www.realvnc.com/pipermail/vnc-list/2003-September/040950.html>,
not to mention all command intercepted!

X is incredibly insecure and network taxing, as well as limited.  And SSH
with screen, with console editor is better, although still
MITM<http://www.signedness.org/tools/>able (and who limits SSH between
servers and the support staff?

SSLStrip will take your local https back to text, not that you are using
webmin or anything <http://g0tmi1k.blogspot.com/2010/04/video-pwnos.html>?

But, yes, we like it fast, from our slow Cox Wifi connections, which
cantrivially be brute
forced<http://www.aircrack-ng.org/doku.php?id=cracking_wpa>by our
neighbor kids....hopefully they won't get a clue what all those root
Nix commands mean?
