Re: [SLUG] X11 Forwarding over ssh
quote who=Kyle I know I could use VNC, but; 1. I have to be able to use std ports to get thru corporate firewalls and 2. I would like to have that connection secure And as best I can tell VNC doesn't support ssh; not to mention I wouldn't know how to send it through a std port without interfering with other services on those ports. Look at the ssh man page (or Google) for port forwarding -- that will allow you to do VNC over ssh. If you have any trouble, give SLUG another call. :-) - Jeff -- Robot Parade http://www.robotparade.com.au/ m. +61 423 989 818 p. +61 2 9318 0284 f. +61 2 9318 2884 -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] X11 Forwarding over ssh
2008/11/16 Kyle [EMAIL PROTECTED]: Peter, for some clarification please. Peter Chubb wrote: On Linux, BSD, Solaris, MacOSX or other Unices that are running X locally, you do $ ssh -f -X host xterm On the host you need to have X11Forwarding yes X11DisplayOffset 10 in /etc/ssh/sshd_config ## So to be clear on this; The 2 X11 params above are set in sshd_confing on the host I wish to control (controlled host)? From a Linux box, I would issue your above command; and from an OSX host, I can use the X11.app (which is I believe and Xterm application). Correct? And providing you have xauth and xterm installed on the remote host, you should get a local terminal window, from which you can run anything you want. ## So these need to be installed on the controlled host? You *won't* be able to run the window manager there (is that what you mean by `The gui' ???). It runs on your local machine. ## I can see the possibility for confusion here. To be clear; My initial question has to do with running the controlled host's desktop much like a VNC or RDP session. Which host it physically runs on, I don't suppose I really mind too much. So long as I can have it all running through std. corporately-available ports. You should however be able to run anything else. The way this works is that clients on the host talk to the SSH proxy on that host which tunnels the protocol back to the display indicated by the DISPLAY variable in ssh's environment on yo ## But if I understand your post correctly, you're telling me how to connect to a host and then run X-based applications displaying on my controlling host, but which are actually running from the controlled-host? Hey, Why not just use VNC over ssh? Crash course: Setup the vnc server on the linux box (system-preferences-remote desktop on Ubuntu) Then in the putty options add a port forward from an available port (e.g. '12345') to 'localhost:5900'. On your windows VNC client you then connect to 'localhost:12345' and it should connect to the remote VNC server. VNC might not be secure or run on the desired (corporate friendly) port, but forwarding it over ssh can help solve both of those issues... cheers, Owen. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Desktop integration with Google Calendar and Remember the Milk
I frequently move between computers, and so have found the 'old way' of keeping all my communications and organisation on one computer to be increasingly limiting. Based on recommendations, I've made the effort to migrate to Google Mail, Google Calendar and Remember the Milk. While it's nice to be free from specific machines, I have found the desktop integration to be lacking. My main bugbear is desktop notification. Gmail is fine here, as it uses standard mail protocols (its IMAP implementation is 'interesting', but it does work) - a desktop applet polls the inbox and tells me when there's something new. The same can't be said for Google Calendar and Remember the Milk. How can I be notified when there is an appointment or to-do item due? Gcal can show a pop-up within the Web browser window (so I need Firefox to be open and visible at all times for this to be useful). SMS and e-mail notification are nice, but not optimal. Remember the Milk has a similar problem, except that SMS reminders don't work here (ironic considering the company is based on Chatswood, but perhaps understandable given how telcos operate here). What I want is a desktop reminder similar to what you'd get with Korganiser/Kontact, Evolution and so on - something in-my-face that I can't miss, but with an option to snooze/suspend. It should also not be dependent on a Web browser being in the foreground (or even open at all). Gcal and RTM _should_ allow for this easily, except that they don't export VALARM parameters in their ICAL feeds. Currently I just use the e-mail notification, but that isn't optimal. So, how does one have their head in the cloud without losing sight of the real world? - Sridhar -- Bring choice back to your computer. http://www.linux.org.au/linux -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] X11 Forwarding over ssh
As ever, ask SLUG and you end up with 5 different ways of doing it. :-) Thanks all. I should be able to get at least one of those working. Daniel, most common problem I come across doing it the remote X11 way is no display setup. And never sure which particular variable it is that the relevant appl. wants. Aside from that however, the wish to run the 'desktop' (a.k.a Window Manager - I guess) is so I can leave programs running, log in and check on their progress.

Daniel, most common problem I come across doing it the remote X11 way is no display setup. And never sure which particular variable it is that the relevant appl. wants. Well, the particular variable is 'DISPLAY', which tells the X11 applications which display server to talk to. ssh X forwarding /should/ set that up for you automatically, including authentication, so that says that something went wrong at that stage. However... Aside from that however, the wish to run the 'desktop' (a.k.a Window Manager - I guess) is so I can leave programs running, log in and check on their progress. ...for that, you need something other than X forwarding -- X11 has no native display disconnection or relocation capabilities, so you would be starting a new session and then shutting it down each time. If you intend to do a significant amount of work remotely, especially over high latency links, then I recommend NX, which others have also mentioned. The performance is significantly better than VNC.

You can cobble together a couple of different services to get what you want. imified.com provides an instant message front-end to RTM and Google Calendar. This could work well for your desktop reminders. I synchronise my phone with my Google Calendar using goosync.com's service, and find it quite stable and reliable. Having my calendar with you wherever you go is perhaps the biggest productivity improvement I've had in recent years. There's also a tool to sync Outlook with your Google Calendar -- sadly I'm forced to use Outlook at work, but this way I can also sync it with my phone.

It's a nice excercise in bash scripting but quiet redundant with
today's GNU grep:
-R/-r/--recursive will replace the find
--include=pattern will replace find's -name ... (though many times I
use --exclude \*.svn-base to skip SVN files)
--colour will highlight the results
Less' -R/--RAW-CONTROl-CHARS will help page through the highlighted output.
So in the end you can achieve the same result with something like:
