[Cialug] X to X

[Stuart Thiessen]

Would this be a helpful thing to put in the wiki?  Instructions on how 
to do VNC and X over SSH or links to a site that does explain that 
well. I have a Mac laptop but also have some other computers with 
Linux. I would like to be able to run X on my Mac laptop and tap into 
programs that are running or can be run on my Linux computers. But I 
have not understood how.

Perhaps that would be a useful set of links or instruction how-to on 
the wiki for those who are newbies or who are just users and not people 
who have the opportunity to use it regularly. I would love to delve 
into the technical side of Linux more but my job has evolved to where I 
am working more as a user, not a technician, so I keep forgetting 
things since I don't do it as much as before.

If nothing else, is there a good Linux User manual that explains these 
kinds of tips and tricks that can function as a reference manual?  Kind 
of like the programming cookbooks?

Just a thought.

Thanks,

Stuart
