[Announce] snx: a simple NX client
Hi all!
I was tired of how bad qtnx works (Fn key doesn't work, crashes, only can run either gnome or kde sessions, etc), so I decided to have a try at it. So, here it is: snx, written entirely in shell script (bash syntax), a command line NX client, able to run commands, any desktop, or even funnier things. Notes: The package and its dependencies (xmodmap, wmctrlm xbindkeys and x11-utils) are provided in extras-devel repository, for both N8x0 and N900. In N8x0, you are advised to install Telescope to avoid problems managing NX windows. With the default diablo task switcher, some NX windows can be "lost" if minimized because they do not show an icon in the taskbar, Telescope will show all windows, fixing that problem. In N900, some remote windows don't receive the input focus (a known problem with the N900 window manager). You can press Ctrl+Return to toggle fullscreen state and give the input focus to the active window. Although it is a NX client, it won't use nxserver, nxssh protocol or the nx account. It just uses your regular ssh account. It works even if nxserver is not configured, as long as nxagent is installed in the remote server. Advantages: Very easy and fast to use. No setup. Keyboard works fully You can run single commands in rootless mode (default) and have the remote windows managed locally (to run several programs, launch them from a xterm) You can run any remote desktop. You can fullscreen the desktop window and the remote program windows with the fullscreen key Limitations: It requires a bash compatible shell in the server's user account (/bin/sh linking to bash is syntax restricted and doesn't work, it must be /bin/bash or /bin/ash...). Actually you can run just one client session per server. This might be improved in the future. Actually it doesn't run on desktops because it doesn't manage X cookies. This might be improved in the future. It doesn't run persistent sessions, disconnecting or closing the NX desktop window will close the remote session. This will be improved in the future. Only X remote sessions and programs. No vnc. No rdp. Usage: Open a xterm and type snx user@host[:sshport] [command] Type the ssh account password when asked. For example: "snx user@host firefox" will open a remote firefox The command is optional, if none is provided a xterm will open. The sshport is optional, you can use it if the host ssh server is listening in a non standard port. Standard ssh client file configuration also works with snx. To run a remote desktop: snx -d user@host start_desktop_command For example: "snx -d user@host startkde" will run a remote kde3 desktop To avoid typing your ssh account everytime, you can set the NXHOST environment variable export NXHOST=user@host Then you can just type snx [-d] [command] Server side: snx fails and you can read a message like: Server says: Error: Aborting session with 'Unable to open display 'nx/nx,link=modem,accept=127.0.0.1:1011''. This is due to a bug in your nxagent version. NX 3.4.0-14 binary packages from NoMachine are known to have this bug. You have to install newer packages from your distro to fix it. Opensuse: Install the NX-3.4.0 package from X11:/RemoteDesktop OBS repository. Ubuntu:Follow the instructions here https://help.ubuntu.com/community/FreeNX You need to install at least nx-common, nxagent, nxlibs and nxproxy packages (freenx packages are not really needed, but it doesn't hurt to install them either) |

Is this like VNC excpet application only?
Or am I just wanting this... well, not konqueror. I can't stand that browser. |

Update: Package snx-0.0.1-1_armel.deb did not reflect the compulsory dependency on xmodmap, uploaded snx-0.0.1-2_armel.deb to fix it. If you have the first release installed, please make sure you also have installed xmodmap, otherwise the keyboard won't work as expected.

Lulz, I use lynx.

The Diablo "Application Manager" complains that both wmctrl_1.07-5_armel.deb and xbindkeys_1.8.2-1_armel.deb are "Incompatable application packages". Do I install these using dpkg or something?

Re: [Announce] snx: a simple NX client
Yes, install them using dpkg, they will work with no trouble.
Btw, I don't understand why Application Manager complains, both packages were built in scratchbox's diablo target. |

New release 0.0.2: keyboard fixes. Now the keyboard always works, even with non-latin keyboards.

Excellent little script. I have been using a hacked jumble of scripts to use my home server over a ssh tunnel and vnc. This is much more efficient for my uses and tons snappier than sending raw X displays over to my tablet. Although I do not have a good screen keyboard option to enter text, I do find it useful for remote and home stuff. Some fun and useful things I've done with it:
