I currently have a RHEL 5.4 software development server. A lot of my developers are using windows desktops and they need to run interactive sessions on the server. I need to support between 4-6 concurrent users on the server. I tried doing this with VNC but I was never able to set that up for more than one user at a time.
View 2 RepliesI have a mate who runs the IT in his office. He has recently set up and secured the network but now has an issue logging in to the network from home. Here is the message I got from him regarding the set up and what he is having specific issues with.
I was really pleased with the results on my Pen Test; the office itself is a pure MS environment but the testers all use Ubuntu 9.10 to hack with. The main tools of choice are Nessus and Ophcrack with a bit of NMap. It's pretty scary what you can do with just these tools. I had a Wireshark trace running all the time and it's fascinating to watch how these guys crack open a system. The only really major change I've had to implement on my network is to force the use of SSL as a transport layer for our remote desktop sessions. This has forced me to start using MS RDP Client 5.2 because it can use certificates on the session. The problem I've got now is that the Terminal Client in Ubuntu can't do this so I can't remote in from home on my Ubuntu laptop.
I have a need to support multiple remote desktop sessions. Each one seperate from the other and run concurrently.
Windows XP supports one. Widows server support two. How many will Ubuntu server suuport? How about Ubuntu desktop?
I want to be able to run multiple desktop sessions, but when I goto the next session terminal and type startx -- :2 the screen just goes all black.
View 4 Replies View RelatedI have a Debian VPS running Lenny and I'm trying to setup a way to run remote desktop sessions from it. I went with FreeNX, NX client for windows from nomachine, XDM and xfce4. All seems to have installed well, but I can't start an NX session on my box. I can connect to the server and authenticate, but the client hangs on "Downloading the session information," eventually timing out. The log output is below - I'm not even seeing an error message. Any ideas?
[Code]...
The only thing I noticed during install, which was about 400 packages since this was a barebones VPS, was that I should consider recompiling the kernel with CONFIG_SOFTWARE_SUSPEND=y. I don't know if this has any impact on session information, however, since this is a new session, not one I'm trying to resume.
I have VMware server installed on this machine. I also have a Windows XP VM running all the time. I have it bridged so it gets a valid IP from my router and such and is in my network. I use KRDC to remote desktop to it and I make it full screen. However if I want to go back to my desktop I have to minimize KRDC.
Is there a RPD client out there I can use so I can go full screen on 1 desktop and have everything else on another desktop then use KDE's Desktop switcher or ctrl+alt+arrow keys to switch between desktops to flip between Windows XP and Linux without having to minimize?
I'm looking for a way to store an encrypted filesystem on rsync.net which can be mounted and used by multiple clients concurrently - I've considered and experimented with many different ideas, including code...
but all of them are leading me to what looks like a fundamental theoretical problem: a filesystem with concurrent access needs someone to manage it, and who's going to manage it if I can't trust the server? Or refuse on principle to trust the server? There would need to be some trusted entity communicating with every client and making decisions to keep the filesystem and/or block device consistent, right?
Is my understanding correct, or is there any way of achieving what I'm trying to do?
So essentially, I have 3 monitors and i'm attempting to run 2 different window managers/sessions at once split up on the monitors. It is intended to be like this:
Code:
[GNOME/Compiz - Screen0]
- Left Monitor[code]......
Usually we require vnc to take remote sessions. There was one another i think it was called xdrp or xrdp. I am asking this out of curiosity, is there any way to take remote sessions using http. Like in web conferencing, we invite users to join the conference and then we are able to share desktop. Is there any way to do this on one-to-one basis ? is such a technology exists for linux (for any disto) ?

Will it be possible to maintain multiple sessions from Ubuntu?Actually we are working on one open source application and we have setup this application on one of our Ubuntu machine and this would act as a server for other developer's windows machine. Is any utility available(preferable open source) using which we will be able to access the Ubuntu server from all 4-5 developer's Windows machines?
Our requirement will be to access the whole system including console and GUI (same like remotely access) by using different sessions so that all 4-5 developers can start work together on the same Ubuntu machine.
I just bought a tablet, I would like to VNC to my machine with a lower screen resolution to match my tablet. Right now I use x11vnc on Ubuntu 10.10, and I was thinking to start another session using "startx" but I see there are parameters for display depth but not resolution.
View 4 Replies View RelatedI have been able to log into a tty[1-6] as root or my user, and then startx -- :1, while logged in as myuser and running X on tty7, , but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?
Related 2nd question: When I did the above startx -- :1, it would start the X session in the same tty (e.g. tty2) where I was logged in when running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work?
I am using putty to connect to some servers. Is there a program that let you connect to say three servers and when you write your commands to server1, server2 & 3 also gets the command? So I don't have to log in to all three servers to do the exact same thing.

I'm having problems establishing secure sessions with my bank's online banking service provider. I've already contacted their local tech and together we were unable to solve the problem. I've tried deleting my cookies, session store, cache, and none of it worked. He's currently forwarding our conversation to the service provider's tech support line, but who knows what will come of it. Or even if they will offer support for an iceweasel user. I'm using Iceweasel 3.6.4~build2-1 out of the experimental repo.
I'm able to login successfully to online banking site to view my list of accounts, however if I try going any further than that, I'm redirected to an error message page that tells me a security error has occurred - the online session has expired. I get this on browser profiles 1, 2, and 3, however I do not get the error message on profile '0' (default) or on newly created profiles. And as mentioned earlier, I've tried deleting all persistent data (cookies, session, cache) on a non-working profile and the problem still exists. Let me know if I can provide any more information.
Running Jessie (with a low-pinned Debian-based repositories added to my sources.list (e.g. Kali, kxstudio) for those packages not currently available on Debian (like the Kali menu of security tools). Running on a HP 15-r189nd (Energy Star) laptop.
First question: How do I get GDM3 to add root as an option during login? I can type the root user name in. I don't need it to show the root user in the user list (would actually prefer to need to type it in), but I do want to be able to start an X session as root, since some of the Kali tools (e.g. nmap) needs root to function fully. If I type in root and try to start, it just takes me back to the GDM3 login.
Second question: When I want to select my Desktop Enviroment/Window Manager in GDM3, the list appears below the little gear so I can only see half of the list (xfce not visible to select). How do I change the GDM3 appearance/settings that will change the position of the DE list?
Third question: How do I get multiple X sessions running simultaneously? What I have been able to do, while logged in as myuser and running X on tty7, is to log into a tty[1-6] as root, and then startx -- :1, but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?
Fourth question: When I did the above startx -- :1 as root, it would start the X session in the same tty (e.g. tty2) where I was logged in as root running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work? Or is there something wrong with my setup?
Question 5: Once I have started an LXDE session as root, how do I get it to show the full application menu that my regular user can see? Can I just copy the config files over? Which ones? Or is there a better way?
Question 6: Gnome used to start fine. Then I ran Gnome on Wayland once, and now regular Gnome (on X?) no longer runs, but give me a "Oops! Something went wrong" error and Alt-F4 just takes me back to GDM3. Classic Gnome and Gnome on Wayland still runs OK. Should I log a bug report?
if i stop that session, and come back later, it will have me log on at the login screen, but start a new session, with multiple instances of things..now, with vino, i could just keep the same session running, and when i VNC in, it just resumes it.. This one starts a new one.. i even tried just locking the screen, and it still starts a new one...i know there is an easy fix.. lol.. i just cannot find one.. i REALLY like how it shows me the ubuntu login on my server.. that is slick, so id like to keep that, if possible.
View 2 Replies View RelatedI have a small problem regarding multiple X sessions. I want 2 X sessions started automatically on boot with 2 different users auto logged in and 2 different sessions running.
On first X session I would like to have gnome running with user1
On second X session I would like to have xbmc running with user2
So far my computer logs user1 in to a gnome session via gdm on boot. But then I have to launch a tty, log in as user2 and then start xbmc in a new X session.
How to make it work? I would also love to have the second X session active after boot. I am running Ubuntu 10.04.
Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.
Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.
I've written a script (that doesn't work) that looks something like this:
#!/bin/sh
screen -dmS "somename" somecommand
for i in {0..5}; do
screen -dmS "name$i" anothercommand $i
done
For some reason, if I copy and paste this into a terminal, it creates 7 detached screen sessions as I expect. If I run it from within a script, however, I get only the first session, "somename," when I run screen -ls.
Edit: If the same can be accomplished another way (e.g. with multiple screen windows instead of sessions), I would be open those solutions as well.
My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. what open source solution i can apply for my problem?

I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.
I maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?
I'm working on getting my myth box hooked up to my Sony flat panel display.Originally the nvidia drivers could not read the EID, so defaulted to only 640x480 over my HDMI-DVI connection.I manually updated xorg.conf with a mode for the resolution I know the thing can handle. Suddenly there are several resolutions avaialble in nvidia-settings and it seems to be communicating with the TV, as it is now listed as a Sony FP display rather than a CRT.I'm able to change the resolution now as expected.my problem, however, lies with the TV itself. I can't seem to get it to actually display the output. I'm able to remote desktop into the box and can see Gnome logged in and everything.However nothing on the TV itself.How do I troubleshoot this? Am I missing something obvious?
