I have the following use case:
1. connect from windoze to local started Gnome session,
2. remote Gnome(Debian Linux) -> to local started Gnome session,
3. connect to local started(Gnome) session.
Until now I've been using xrdp while on windoze and a vncviewer while local or remote Linux machine, but when local I have the pb: I use 2 Gnome sessions with the same user: local GUI desktop and second, where I actually run my programs(the VNC session). Many of the desktop settings are stored by user so when changing something on VNC session changes are lost because of the interfere of local session. My workaround is using different users for local and VNC sessions.
Other solutions I tried:
1. vino remote desktop - can't use it as other local user is using that machine as desktop while I need it also.
2. XDMCP/xnest - needs X server on windoze and not sure if I can reconnect to the local session(?)
Other solutions I heard of but I did not try:
1. freenx - I read about it and it looks it can do what I already did with VNC: reconnect to a locally started session - the pb with 2 sessions of the same user may still be there unresolved.
Freenx is only a relevant project if you need LOTS of simultaneous connections. If you only require personal administrative access, you can use the original NX software from nomachine.org. This provides a MUCH better configuration experience than the freenx projects attempts, and is, as far as end to end remote desktop solutions go, very good.
Ultimately though, I'd urge you to work in a way that means you don't need access to a persistent remote graphical environemnt in the first place. Terminals rule.
I do admire AK, but disagree with him on a few things. VNC is wonderful (IMOHO) just slower than RDP. You are using it for the virtual desktop if you use XRDP (xrdp 'just' starts and maps the VNC session and the RDP protocol).
It sounds like you plan to loopback form one desktop session to view/control another session using the protocol. Used that way scale is unimportant, network latency is irrelevant, and security is a non-issue.
I would run some tests and see if VNC would work for you, simply because that will be fast and easy to implement. If that does not work for you, there are always other options to fall back upon.
I realized that what I want is a remote terminal service solution:
As server side I have 2 solutions that I know of:
I'd give a try to x11vnc because maybe it provides a more general solution.
Although, there is no requirement to have it accessed from mobile devices yet, this may be needed in future.
Are there any freenx clients for Android, iOS, MIDP ?
I have some info here:userlogin
but seems not trivial to cfg.
the nomachine nx client with the nomachine nx server is very simple, as they both come preconfigured with the same default RSA key. if you used freenx then you need to put in your own key to get started. I mean, you SHOULD put in your own key either way with NX, but at least you know it works with the defaults.
the free admin version of nx is only 1 or 2 connections though, so maybe that might be a blocker after all. That's basically why the freenx project was started AFAIK.
NX is not only limited to two connections--it's limited to only two different users. This became a drag for me so I switched to freenx. I installed it on about six linux servers that I administer and the only thing I had to do was to copy the key from /etc/nxserver/client.id_dsa.key to the windows nomachine nx client.
A few days ago I installed Fedora 16 on my home PC and I have not yet been able to make freenx work on that machine. Not only that, I accidentally removed it from a server at work and am unable to re-install it. I'll post back when I resolve my problems.
It certainly depends HOW you use it as to how useful it is. I certainly have never heard of that limitation. Do you just mean the running sessions, which I guess would naturally be limited by how many users are already logged in? Depends what "concurrent" really means to each person I guess.
I used to work with my PC for a long time during day times. My system used to slow down or even hang whenever I used to install or download a new software or function. Is will be problem to down load the attachments regarding the Remote Desktop solutions? I am in search for this information as I am in require for this. Could you please produce some attachments regarding my problem and also their price details?
