This does not, as I am typing, include generating the id_dsa.pub but... I just put that part in from another script. I include -X and Compression so running a GUI is possible even across slow links. Sometimes we start... vncviewer -bgr233 -noraiseonbeep -nocursorshape -quality 0 \ -encodings "copyrect tight hextile zlib corre rre raw" \ -compresslevel 9 localhost:0 To 'peek over the shoulder' of our clients. I don't advise that unless you are on the phone with them at that moment because they freak when mouse moves and screen gets typed to without them. Diverting messages from expect so your novice users will be less intimidated I leave for the readers because I have spent too much time on this already.

Remote access partition and install Linux. With a Near Zero skilled operator at the remote site.
by Oren Beck 23 Jan '08

23 Jan '08

The reasons for this situation are several at more than one location. The overview is to remotely install Linux on computers owned by non tool users, zero skills presumed of them. What I am seeking is several methods for making the process just plain work. Initial customer is my mother in Berkeley, and her social groups may join in. The minimal cold start scene will be a Knoppix or Damn small tested computer and net connection. The defined factors are: DSL or cable modem set up as DHCP. Hardware approx 2000 or newer. Working OS of XP or installed Knoppix or both.in most cases. Very Few sites with no OS. Internal HD swaps are a non starter as most of these folks are non tool using mundanes. The rest of the story is they almost all are politically or socially desiring to use Linux.by choice! With a few skeptics that "want to be shown"-more about the net than Linux as they still use TYPEWRITERS! And they often have little to no computer skills to unlearn. Short of my doing some major frequent flier miles tripping,KCLUG may be their salvation. "Someone is going to do it- why not us?" -- Oren Beck 816.729.3645

Cisco 3750 Switch
by Kelly McLaughlin 23 Jan '08

23 Jan '08

I know we have some great minds in this group. I have a question for a network guru. When creating VLANs in a Cisco 3750 switch, can a single interface port belong to more than one VLAN ??

Personally I just want something which prevents the need to look up the command line options every time I want to try something different. That would suffice for mencoder and transcode. However, the GUI was to be for my friend with his interest in Astrolog. ____________________________________________________________________________________ Looking for last minute shopping deals?

Quick GUI frontend development for command line tools?
by Leo Mauler 20 Jan '08

20 Jan '08

There are a few command line applications for which I would like to have a GUI, or for which I've found a GUI I'm just not happy with. I use mencoder and transcode a bit but I'm not happy with the GUI frontends I've found for those applications. I also have a friend who is interested in the Astrolog astrology application but who is very unhappy with the command line interface, a potential Linux convert if a GUI can be discovered. KAstrolog has been out of development for so long I can't seem to compile the thing. I haven't written any code in ten years so I'm looking for something to create GUI Frontends without too much programming experience. ____________________________________________________________________________________ Never miss a thing.

It will probably become a red giant and swallow the Earth before it collapses. We better start building our REALLY GOOD bunkers now! ;) <- notice the winky face???
