</a><br></blockquote></div><br><br>How does nxserver use "su" to impersonate the intended user, out of curiosity?<br><br>I realize you only get an nxserver prompt if you were to ssh in using the default key. I assume that the nxclient issues commands of some sort to execute su and other tasks, what commands are those? Are they plain text commands or some sort of additional authentication/encryption/whatever performed at that point?
<br><br>I haven't had the time to do anything further with nxserver, myself. I absolutely require cygwin to do many of my day-to-day tasks at work, and the fact that I apparantly must choose between Cygwin or NXClient has pretty much caused me to abandon my nxclient investigations for the moment and return to tightvnc tunneled over SSH. I see there's something called the "web companion" but since I don't intend on running a webserver on my target machine I'm not sure if that's any use to me.
