Debian Configuration :: Remote Desktop / Firestarter?
Apr 4, 2011
I have a bit of an odd network setup, shown in the pic here:I am trying to remote desktop from the XP boxes on the side to the one on the bottom, behind a Debian box/firestarter firewall. Is this possible to do without changing my network (IE wiring/topology) setup? If I had my druthers, I would put the router behind the Linux box, before the XP box, but my work laptop does not allow me to connect in that fashion as I can't change the internet settings.
I am certain the setup is correct on both the Windows clients and host, so it has to be something with my firestarter firewall, or something else I'm completely missing. I have the RDP port opened on firestarter, but whenever I try to connect to the XP box, whether it's by computer name or LAN IP address, it is unable to connect. I had thought about setting up a VPN server on my Debian box, and then VPN'ing to it, and then in turn RDC'ing to my Windows machine. Is this possible? If all else fails, I may just plug the Windows box directly into the router and deal with the lower security or get a second wireless router just for my work pc.

I cannot remote desktop to the Debian machine from anywhere,hether within the same network, or on a different network elsewhere. Also, the personal wiki I set up on it to be viewed via a normal web browser cannot be accessed, either. Both time out when attempting to connect to them. I can still ping the Debian machine when on the same network, though.
This started some time ago when we had a failure occur on our main server.had to powercycle everything in order to restore things back to normal, the Debian machine included. Since that time, this problem started to occur. This is a major thorn in my side in attempting to prepare for our website to move,I've been unable to figure out how to fix it.Originally, I thought it would be something in between the Debian machine and anything else, which would mean something like our firewall box or our hardware switch was the problem. But the tech support people who maintain those for us confirm that there is nothing wrong with them, so now I'm not certain anymore.

I'm trying to get an laptop running more or less like a headless server, my reasons are not all that serious. Mostly I want to leave the laptop running as a seed box when my main PC is turned off, also want to setup it up as a media top, common place for media files and playback on Tv. So essentially I want to be able to access the remote machine, preferably sharing the same session and persisting while I log out from remote.
What I've done:
setup keys for ssh to connect automatically between machines, so I can login via terminal, access the file system without issues, which is already a great step. enabled remote access on remote machine lightdm manager setup deluge for daemon torrenting, which enables almost seamlessly client to connect remotely (though deluge is not the best with speed)
What I've tried so far:
Connect directly with a new X session
Code: Select allX -query your_server_ip :1
Works alright, creates a new display (:1) which is oddly in F2 tty instead F8 as is expected. Works alright, not much lag, audio is not routed.
But an issue! whenever I decide to log out X will simply shutdown, screen goes black and I can't resume on my regular session on my local machine.Connect X with nested Xephyr session
Code: Select allXephyr -query your_server_ip -screen 1280x1024 :1
This works too and might be the best solution yet, a windows is created and the remote session is nested in your current X session. Visual and performance is ok. Only real issue is that session is not shared, eg, application will not remain running...Connect via VNC
So it seems only solution for shared sessions is VNC.
With the remote desktop apps from KDE (which is the DE for both), I can connect buzz around and etc, but its kinda cumbersome and laggy, password always resets and I usually need to accept on the remote machine.
I've tried setting up lightdm to allow a vncserver at logon, but this is erratic at best, took a long time to get the Xvnc command correct enough for me to login remotely, and even then got a garbled screen and the X session wasn't even the same...
So that's it... Isn't there a way of regular X session sharing in the remote computer? Or a better solution for lightdm vnc invoke?

If i got gnome i may go to the top-panel: choose system, choose preferences and go to "remote desktop" and make my settings (allow, ask for allow, password, and other stuff). I don't want to be bound to gnome (though i like it, thats not the problem).Which config-files are the ones i am looking for?
I did search the web, but i can't find useful how-to's, explanations, etc.Cause what i find is related to the path i described above (gnome: top-panel, preferences...)Which is the app/tool which pops up and says:"someone wants to access, you want to allow it, yes or no?". The performance of VNC is lousy comopared to NX. Lousy is the friendly version. What might i be doing wrong?i usually do it from a Debian-host to a VirtualBox-guest.I am mainly asking for how-to's/docus and stuff like that. Links. Explanations are welcome too. Of course.

I 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 installed Firestarter, and set it up following some manual (just a simple, baseline setting, nothing fancy). However, after restart I got error message: Starting the Firestarter firewall... failed! and then, later: startpar: service(s) returned failure: firestarter ... failed! Why this happens?

how to configure my firestarter firewall. I have a website which requires the port 1935 to be open. I figured out how to open the port using firestarter. Is there anyway to make the port open only to this website, and not to every other website for security reasons of course.

I installed Firestarter firewall on debian Squeeze.Now i note there is a gui available in System->Administration which apparently does not need to be running all the time - its not set up to start on boot.When I boot I notice the boot message has a line saying "Starting Firestarter firewall .... failed"When I am logged in and type "/etc/init.d/firestarter status" as the Firestarter FAQs say, I get"Firestarter is running... ... (warning)"I can run the gui manually and still same message.

I have just recently installed firestarter to get an idea of iptables editing with a GUI. Firestarter works great and I love it, however when I turn my system on, and my system is booting up the terminal displays a "Failed" message when attempting to start up firestarter. Now I have been doing my homework (reserch) and have read that a user will get this error because firestarter trys to load prior to the network manager starting up. I have also read some other variables that can cause this is if you use network manager and have a password on your user account (which I do have) can cause this issue.
However in most cases from what I have read is even though it gives the user a "Failed" startup message, once the user logs in, and is connected to the internet firestarter will actually load the iptables. I did some tests and from what I understand I can see that this is true because I have allowed access to certain torrent trackers, and denied access to others, and I can see some come online. Does firestarter load iptables once the user logs in? Or once it fails to load, does it not load at all unless you manually open/load the application. If firestarter just modifies iptables, then once I save my listings in firestarter then I really don't need it to start up correct?

remote desktop requires authentication on server side when trying to login remotely via VNC. I have the option set to not require confirmation of each access to the machine, I set a password that the user must enter from the client side.just testing this locally over my LAN, VNC connects and asks for a password(the user field is blank; might be nice to have to enter a valid username and password so I don't have to share a general password). after entering the password on the client, a window pops up on the server 'An application wants access to the keyring Default but it is locked' and requires me to enter a password, which once I do then the VNC gets control and all is good... but obviously if I am trying to remote further than down the hall this won't work.
Ideally I would like to remote into ubuntu desktop with account credentials from the server and require no physical person at the server to allow access. I currently have an XP pro box setup this way with remote desktop and works flawlessly. I want to keep it true to the same functionality where when I log in remotely it joins a session with applications already running, such as a web browser and mail client, with those applications left running when I logout of the remote session. its not all that important if it locks the server side locally as there will eventually be no physical access to the machine once its been setup.
as you may have noticed I am fairly new to linux, but very willing to learn. my primary reason to move to the linux platform is that I am hoping it will provide better performance than windows XP/windows 7 when I upgrade the box to an atom based mainboard. any other thoughts or recommendations on my planned setup would be greatly appreciated as well.just to be clear, the 'server' is ubuntu desktop and client side is generally windows XP, windows 7, windows server (I work almost exclusively on windows boxes)

I need to work with other computer. How could i make it? Should I use SSH over VNC, or?... There is a lot of information about it, but, maybe, too much information. I just need to connect to my other desktop. In win i've used TeamViewer. What should i use here?

Upgraded webserver to Jessie as an upgrade to Wheezy produced errors, and before reboot everything was up and running, but as all upgrade docs and info I read, I rebooted the server. However it never came back. I have the original backup files before I did the Wheezy upgrade. I also have access by Rescue to the server.Made a back up of critical files and have a 24GB tar file and I can connect by SFTP.
how to check the Debian files... Grub etc.. I would prefer to find the issue than start again.I am not able to sudo from Putty. I cannot run apt-get update. I did go to chroot, but then I get unable to resolve host errors and Could not open lock file because Permission denied errors and asking if I am root.There is information by googling for start up issues, but as I am working remotely with a Rescue set up, a lot of the commands I see and have tied do not work.

I have two remote systems which I have fstab entries for on the local system. I have them set to noauto, because mount fails during boot for some reason, but that's not the problem. For years I've mounted them in rc.local.
The problem is after I recently reinstalled Debian, when I mount them manually it always asks for my user's password. I've copied my user's pub key from the local to the remote system and put it in the user authorized_keys file (not root), like I always have. But it still asks for a password, and so fails to mount in rc.local.

I have just setup a debian box, and I want to be able to login to the machine remotely.Currently I have the following setup:Cable Modem -> Netgear Router (DHCP to outside world) -> Debian Box (DHCP for internal network)As I under stand it I have to set my Debian Box to use a static IP, but from there I di not know where to go.Also since my cable modem IP is dynamic, is there some way to have that the debian box get the IP address for the outside world, and e-mail it to my gmail account when it changes, or least every X hours?

I'm going to install Debian on a friend's desktop. Since he lives far from me, I think that being able to administer his machine from remote would be nice. OpenSSH is supposed to do that, isn't it? Thus, I'm going to install OpenSSH server on his Debian, but - to avoid security holes - I'll write two scripts to start and to stop the OpenSSH service; he will run such scripts whenever I need to check his machine, to make OpenSSH server available only when needed. I'm also aware that disabling console access for root is better, and that I should log in as a regular user and then do "su".

I just installed Debian 8 and ran vnc4server. I want to get Gnome on a client computer so I read some threads on the internet telling me to edit the ~/.vnc/xstartup file, which I did. Unfortunately I've tried multiple edits of this file and I cannot get it to work properly. Any working script of what it should look like for the latest stable version of Debian?

I've gotten VNC setup and working well on our LAN. The next step we want to do is making it acessible from the web, so we can remotely do things with the office files.Unfortunately, I have no idea how to go about this.Our current setup is a router which connects to the phone line, and into which other devices are connected. We're in one room of a big office building which may complicate matters somewhat.Can anyone provide a bit of general info on this topic. Give me somewhere to start ?Ultimately we want to be able to connect to the vnc port from anywhere in the world.

I have a windows 7 box and a debian 5.0 box connected to a linksys wrt300n router. I can access the linux box from windows 7 through ssh. I used to be able to access the linux box from outside the LAN, but when I was messing with the ssh port configuration (at least I think this was what happened), i lost my ability to connect. I tried writing a new sshd_config file so that it is much simpler:
Protocol 2
PasswordAuthentication no
UsePAM yes
I tried directly connecting the linux box to the internet to rule out a router firewall issue that i was missing. iptables -L yields nothing, as I have since rebooted the machine since messing with iptables rules. But still, when I try to ssh in from outside the LAN, I get a connection timeout error after a 10-15 second hang.

I've got a fresh Wheezy/Xfce install.I'm trying to access a remote samba share the gigolo way. It is an external USB hard drive connected to my router. I can access it read only using the following URL with Icedove: smb://bbox/
Anyway, this is just to try and give might-be-useful information, but ultimately, I don't really want to use fusesmb. I would rather have the gigolo way working, allowing local network shares browsing, auto-connect, etc.

I've setup Debian 6 on a PC and allowed remote desktop to it.
I'm having an issue that everytime I remote desktop to it via VNC it ask for the default keyring password, but how am I supposed to enter this if I'm not by the computer that I'm trying to remotly access? Can gnome keying be disabbled altogether? Never had this issue with Debian 5.

My wife has taken over the desktop (ubuntu 14.04 LTS). I've setup a second wireless router, dedicated to the MAC address of my laptop (debian) and using ssh I can view my email (thunderbird), but I'm not sure what to do to view woodworking videos without downloading. So, do I need to setup tunneling, do I need to view the windowmanager or is there an way to run videos? Anyway I've come along way using HOWTo's with breaking debian. Not sure how to proceed.
Note: The primary wireless router is from my ISP.

I installed firestarter and then at a later date uninstalled/purged it, both actions via synaptic. I have a very verbose boot, I like to see what's going on, and noticed after the uninstall/purge that I was getting an error zooming up the screen containing firestarter in it. After many restarts I found that a file was left in /etc/network/if-up.d/50firestarter and this file was simply a script trying to restart firestarter. At this point I've commented out the calling line and followed the commented line with exit 0. This removes the error but there's still a link calling the file so, is this a bug or am I missing something? It appears the uninstall/purge wasn't entirely complete.

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 running testing, so yesterday I upgraded to the new kernel (2.6.38). Unluckly I can't get to the desktop, because the system just hangs (screen goes black then nothing happens). I have found that my problem is the radeon (open-source) driver. When the it tries to get to the desktop it enters an infinite loop, so the system hangs. The bug is better described here: [URL]. However, I don't know how to fix it. I would prefer not to go to the fglrx (proprietary) driver because of tearing issues.

I was wondering if a standard Debian 8 system with Gnome desktop does any kind of local dns caching, and if so, what the command is for clearing it. (Assuming I haven't purposely installed any DNS server software.)
I found multiple posts on the Web about unix DNS caching, but with widely different answers across distributions and across time.
