I use FreeNX as the server and use NoMachine's client and now also use OpenNX since it works well with lion-10.7. The access over broadband internet is just like sitting at the computer--works great to manage remote servers running Edubuntu/ltsp. I hear it is even a decent experience over dial-up. So, while I don't know what the compression is, it must be pretty good to work this well in this situation. If you have more questions, let me know.<br> David<br><br><div class="gmail_quote">On Wed, Aug 24, 2011 at 7:15 AM, Jeff <span dir="ltr"><<a href="mailto:jeff@wildcoast.com">jeff@wildcoast.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> <div style="word-wrap:break-word">Hi all,<div><br></div><div>I don't have easy access to a server at the minute, and not sure where the settings are anyway; but I've been wondering about this for a while and am just hoping that someone can point me in the right direction:</div> <div><br></div><div>A week or so ago when I was onsite at a school, I ran a binary tcpdump to get an indication of network usage with approximately 12 thin clients working.</div><div><br></div><div>It wasn't a very precisely measured test or anything, but the server sent/received a Gigabyte of traffic in about a couple of minutes.</div> <div><br></div><div>So I'm just wondering whether SSH compression is enabled by default or not?
