[olug] A TCP/IP mystery

[Jay Swackhamer]

Is it actually tunneled, or are they using sftp/scp?(please dont tell  
me they setup a ssh tunnel and then use FTP)

I've typically witnessed windows machines using sftp/scp/other  
encrytion only getting around 3Megabytes/sec through an encrypted link  
on a 100MB or 1GB network, and on the same network, two linux boxes  
will get 10-11Megabytes/sec.

It would help to know what they mean by 'blocking'. Using tcp the  
connection should be slower or faster, but not just hung.
