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?
I 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.
Is there a RDP client that supports version 7? I've been using rdesktop, but as far as I can tell it only supports version 6. The main reason is that version 6 doesn't support the Windows 7 Aero theme.
When either of the proprietary Nvidia drivers are enabled, viewing the desktop using a remote client (Windows TightVNC) does not work. The initial remote screen display is ok, but no updates to the remote display occur. Reverting back to the non-proprietary driver solves the problem. I have also tried using a 10.04 Live CD and used Remote Desktop Viewer on the client machine, and it behaves the same way.
I love Ubuntu but there is just one thing that I cannot get working. I have vista on this computer (Which I am going to delete after I get this working) when this computer is booted into vista then I type "192.168.1.65" (which is this computers internal ip address) and it connects to it without a problem. When I try this on ubuntu with KRFB running I type "192.168.1.65:5900" as it tells me to do with the added port number. This computer (This is the one I am Connecting to says "The remote user has been authenticated and is now connected." and when I hover over the icon it says "Desktop sharing - Connected with 192.168.1.70" which is my laptops IP address. On my laptop however it says "Remote Desktop Disconnected Because of a protocol error detected at the client (code 0x1104), this session will be disconnected. Please try connecting to the remote computer again." No matter how many times I try it doesn't work.
I am using VNC to login to remote machine (vncserver). My question is; How can I login to remote machine (vncserver) through VNC client, without having to login to vncserver first physical. For better explanation here is an example: If john wnat to login to vncserver remotely first he has to login the vncserver physically then he can login remotely.
I have Fedora installed on a netbook. I customarily mount several NFS shares on this machine, from both a desktop system running F11 and a small server running FreeBSD. On the server side the shares are write-enabled. On the server side the shares are write-enabled. In the past this has worked fine.
However since upgrading to F12, my configuration no longer works as before. Reading from the NFS shares is no problem, but as soon as I try to write to one, either in Nautilus or from any other program, including on the cmd line, all hell breaks lose. Nautilus crashes, and I am unable to remount the shares. Usually rebooting the client is the my only recourse.
There are no clues in dmesg on either the client or the server. In terminal trying to remount a "trashed" share I see this:
Code: $ sudo mount -v venus:/media/disk8 /media./disk8 mount: no type was given - I'll assume nfs because of the colon mount.nfs: timeout set for Sat Feb 20 17:34:59 2010 mount.nfs: prog 100003, trying vers=3, prot=6
The NFS versions under F11, F12, and FreeBSD are the current ones (all updates applied).
Well this is my first time using redhat 7, the install went fine and webserver, mysql, phpmyadmin are all working......great
The only problem i have is the remote desktop
I have set the password in preferences/remote desktop run command vncpasswd and set password
In services vncserver i get this message......... xsetroot: unable to open display '' Xvnc is stopped and vncserver failed. The error was: xsetroot: unable to open display '' Shutting down VNC server: 1:user1[FAILED]
Starting VNC server: 1:user1 [FAILED]
My vncservers file looks like this
I have tried restarting service using root login and user1
I can successfully connect to a remote Windows Computer using Terminal Server Client but I cannot save the profile (Fedora 12).This means I have to enter the details every time I wish to connect. As I have many different remote locations I need to access on a regular basis is there any way to save the profiles?
I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface
When ever I have an issue with our LDAP server (which I was able to fix) we see the following errors in /var/log/messages and it causes problems with our services running on that box, e.g. httpd, nrpe, xinetd, etc. Aug 8 17:44:42 hostname httpd: nss_ldap: failed to bind to LDAP server ldap://serveraddress/: Can't contact LDAP server Aug 8 17:44:42 hostname httpd: nss_ldap: reconnecting to LDAP server (sleeping 64 seconds)... I am only wanting to authenticate SSH and Sudo and not services like httpd, nrpe, xinetd etc.
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface auto lo iface lo inet loopback
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.
I have configured server ubuntu 11.04. Everything works fine, but there is a need for some clients to connect local hard drive. What should I do? How and what modules are added to the ltsp-image? How to register in the fstab on the client? Maybe I'm going the wrong way?
i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect. I changed my server firewall settings[Fedora 11] and added "udp 60178" to trusted ports but still nothing happened. I ran wireshark and observed that packets are coming to the server machine but server returns a "Port Unreachable" ICMP message and doesnt give the packet to the application.
I am looking for a client/server application that can allow me to have remote GUI access (eg: VNC) but with the ability to use sound.
I see that TeamViewer has a linux application out now but for my company, it would compromise security protocol because it reaches out to the TeamViewer servers to do any work.
Basically, we have applications that require a GUI and we need to hear sounds from them if they throw an alert (the app is a monitoring tool).
We are running a VNC server on it currently and when our monitoring machine was on Windows, TightVNC was able to get the sound...that is not the case with any Linux client so I am wondering if there is actually one that exists.

I want to get the connected client MAC Address after accept() call. I can get the IP address of the client but i don't know how to get the client MAC Address in my this programme. Here I am Posting my Code.
I have been trying to install the KDE desktop via terminal services, but am failing because I have forgotten the syntax. Could some one please help? I know I did this for Gnome before, so I think it would be just as easy to install KDE with all it's dependencies.I am running Mandriva One Spring 2009 on my laptop and Mandriva Free 2010 on my desktop. I want to install KDE environment on both.
I'm SSHing to a headless Ubuntu box and sometimes need to upload files from that box via FTP. The built-in FTP client does not show the progress of my upload (or at least I don't know how to view it). I just see this during the operation (which could take up to an hour):150 Opening BINARY mode dataonnection for MyFileAre there any FTP clients which I could use in terminal and would show the progress (some kind of a progress bar or just the percentage)?
