Re: Xterm, Cygwin, etc
As I already hinted, I don't see a problem with X security per se. You are probably seeing or hearing about security issues because of cases where people disable X security. For decades, X has had its own crude 'xauth' control. The trick is to prevent hijacks of that, protection which is commonly available. CYGWIN/X can be locked down just like other X servers. (Here we are not addressing Windows security concerns.) Given that, an 'xterm' running on it is not a serious risk. Within that 'xterm', run 'ssh' with X tunneling, and your remote X apps are similarly secured. (Here we are not addressing security concerns on the target, which could be any op sys.) Summary: don't fear X, don't fear CYGWIN. -- R; Rick Troth Velocity Software http://www.velocitysoftware.com/ On Mon, Aug 1, 2011 at 14:47, Gentry, Steve steve.gen...@westernsouthernlife.com wrote: I still like to occasionaly connect to zLinux and use the GUI Desktop interface.

Re: Xterm, Cygwin, etc
vnc is what I use..startup vncserver on zLinux .. use a vnc client ( tightvnc.org has a free one) to connect. You can also use a web browser and the 58xx port. Need the firewall to allow 59xx and/or 58xx ports.

Re: Xterm, Cygwin, etc
Hi, Steve, -- Actually, there is not necessarily a security problem with 'xterm'. But for the moment, I will defer that discussion. For remote desktop, I use VNC heavily. You get good security if you lock down VNC where it runs (ie: set it to reject remote connections) and then connect via tunnel over SSH. If you have a VNC already up remotely, then connect something like this ... ssh -n -L 5910:127.0.0.1:5910 thedesktop sleep 30 vnc viewer :10 (Above assumes you are display :10. Change the last two digits of the 59xx port to match what VNC tells you.) Where thedesktop is the system where your virtual VNC desktop is running. You get a secure tunnel from port 5910 locally to 127.0.0.1 port 5910 on the target system. There is overhead, but VNC is somewhat less chatty than X itself. In my experiences, VNC comes up with TWM -or- with no window manager by default. It is really easy to kill TWM if started and then to bring up GNOME or KDE in either case. The biggest problem I have is sometimes ugly color planes. (Also lack of audio, if that matters.) There are other remote desktop solutions. -- R; Rick Troth Velocity Software http://www.velocitysoftware.com/ On Mon, Aug 1, 2011 at 14:47, Gentry, Steve steve.gen...@westernsouthernlife.com wrote: I still like to occasionaly connect to zLinux and use the GUI Desktop interface.
