I'm trying to VNC into a computer that does not broadcast it's ip address. I can ssh into it though, for example, by first ssh'ing into a computer that does broadcast it's ip address.
Someone told me the following would work:
Code:
vncviewer -via user@externalhost internalhost
but I get:
Code:
channel 3: open failed: connect failed: No route to host
vncviewer: VNC server closed connection
I tried to connect to the server with vncviewer Therefor I installed vnc-ltsp-config (repo EPEL) I configured /etc/sysconfig/vncservers
VNCSERVERS="9:roland"
VNCSERVERARGS[9]="-geometry 1600x900 -localhost"
I was wondering if it was possible to put something like a linux image on to a hard drive to install the OS on first boot. The reason I want to do this is because of the following reasons. First, I broke the IDE port on the mobo so I can't use the internal DVD drives on the computer.
Second, I don't have an extra SATA DVD drive lying around. Third, for some reason, this computer will boot from a USB DVD drive but once it starts loading the kernel, it just stops calling the drive and the computer freezes. I tested the disc and the drive with another computer and it works fine.And forth, the computer refuses to boot from a USB flash drive with linux on it. So as you can see, I'm in a bit of a pickle here. I would love to be able to hook the hard drive up to another computer and put the required files on the it for it to boot up to an installation.
I accidentally formatted my internal HDD and unmounted it and now my computer won't detect it as a bootable device. I have a system recovery disc but it doesn't seem to be making any difference. Also I do not have my windows 7 installation disc nor can I write discs.
Is there a way I can fix this and keep all of my important files?
basically just wanting to find the UUID for my internal disc drive. Running Slackware 13.1

View 1 Replies View RelatedI use vncviewer (win32) to connect to my SuSE 11.3 box. The SuSE box has the "standard" xinetd started Xvnc server running (includes the -inetd switch).
My client (the vncviewer) has to go through a firewall with limited ports available and so I use the command line:
Code:
However, if there is a problem with the connection, such that the client disconnects, it seems that subsequent request to the Xvnc server create a new session/display. The text in the client window reports "nobody's x11 desktop (host:1)", then "...(host:2)", then "...(host:3)" etc.
I have tried combining the display and the port parameters, like this:

View 1 Replies View RelatedI managed to install Centos x86 for the first time, together with VncServer, SSH access, mySQL and Apache. Everything worked greater until I logged in remotely to the server from my Windows 7 machine using RealVnc. I manage to connect successfully and able to use the GUI remotely. However, when I press logout from the menu, the screen gets stuck on the funky blue and white curly background. It does not close automatically.
If I close it using the 'X' button and reconnect, I get in to same stuck screen. My only workaround is to login with Putty and type 'service vncserver restart'. Then I am able to connect again. But same thing happens when I do a logout.
I've installed TurboVNC and also libjpeg-turbo on Centos 5 to view a Windows computer. I previously have been using TightVNC and it worked great. When I connect to the server using vncviewer, it will only occasionally refresh the image, like when I change a browser window to full screen.

I use vncviewer command line to remote access my pc from my notebook.
Is there any option to resize the view like windows client can by percentage?

already look here: http://linux.die.net/man/1/vncviewer but I don't see any option to do that.
I set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.

View 2 Replies View RelatedI have two Linux computers and one small home router with DHCP functionality. I configured the router with the "dynamic DHCP" setting, ie, the static DHCP with MAC-Address was not used. Before that, I used the manual IP configuration, defining the two computers' names in the /etc/hosts file.
Example:
10.0.0.2 comp2
10.0.0.3 comp3
Now, with DHCP, the above example is no longer appropriate, because the DHCP server is supposed to tell the computer what IP number it will receive. However, I am missing something, because I haven't figured it out yet how to make one computer know the other computer's name. Is it that I haven't installed a name-finding package? Is there a simple way to accomplish this (one computer finding the other computers' names)?

View 4 Replies View RelatedI am currently working with a cloning project using FOG on Ubuntu 10.10 (Desktop). While there is certainly a learning curve, all seems to be going well.
For the initial project, I have this "cloning network" isolated completely. Meaning, it is not connected to my main network/domain switch - FOG is handling the DHCP, I have a dedicated managed switch handling the routing between the FOG server and the client clones.
The main problem I am having is that Ubuntu is not able to resolve the hostnames of the client computers.
I know this is because I do not have DNS setup on my Ubuntu PC.
What is the best route to take in order to resolve this? Can I use bind9 to take care of it, or is that too complicated for what I need it to do?
CLIENT A - 10.10.10.2

ROUTER - eth0 - 10.10.10.1
ROUTER - eth1 - 10.10.20.1
[Code]....
Everything is working fine and CLIENT A can talk to CLIENT B and vice versa, with only one problem - CLIENT A cannot ping 10.10.30.1.
I checked routing several times, there is no NAT and firewall is disabled on the SERVER.
CLIENT B can ping and access any device in the diagram. CLIENT A can ping and access any device in the diagram too, however cannot ping eth1 of SERVER (10.10.30.1). ROUTER can ping any device in the diagram except eth1 of SERVER (10.10.30.1).
If I launch 'ping 10.10.30.1' from CLIENT A and run tcpdump on SERVER eth0 I see no hits at all. If I launch 'ping 10.10.30.1' from CLIENT A and run tcpdump on SERVER eth1 I see ICMP requests coming from CLIENT A but no replies.
It doesn't look like a routing problem because clients A and B can communicate with each other. Also, we have around 20 similar installations but this is the first time CLIENT A cannot ping internal interface of SERVER.

A mycat.kgn 192.168.0.1
A samba.mycat.kgn 192.168.0.128

dns: 192.168.0.129
ldap all machine to zimbra.mycat.kgn for login info and password.
map drive g: to samba.mycat.kgn data-share (with users rights from ldap)
I tried to do this in virtualbox, but fail badly! I created 6 vm using ubuntu 804 and 910, but my dns was not getting any records with dig, so I found an howto on powerdns. But I had to use mycat.com and not mycat.kgn?
I will draw my network to be!
each machine:
ip: (sameas above)
gateway: 192.168.0.1
dns: 192.168.0.129
dns-nameserver 192.168.0.129
nameserver 192.168.0.129
and if the dns server does not find the info it forward it to the gateway 192.168.0.1
Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.
192.168.0.2
192.168.0.3
etc...
My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.
Basically, i want to be able to type a domain in my browser e.g. default.dev and it direct to the ../www/default folder on the Ubuntu Server on my network. The reason being is that as a web developer i have a number of sites that i'm working on locally and i'm getting tired of adding the domain to my hosts file and then creating a virtual host in Apache - i believe this can be done with BIND - is this right? If so what steps are required?
View 1 Replies View RelatedIf I try ping a host on my internal lan from my ubuntu notebook the host name never resolves, but if I ping www.domainname.xxx it will resolve because our dhcp server is setup as the dns server too. If I use the connect to server tool and select samba share and specify host by name, it can resolve that and the shares show up... same dns server, same machine, but different interface/program. My real reason behind this is because my synergy+ keeps falling over whenever the synergy servers dhcp lease expires and it gets a new I have to then specify the new address and change configs.

I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?
I am not too knowledgeable on networks, however I think this should be possible.I have a computer at work, which is connected to the work network. I have files stored on the central server here and also my local computer.
At this place, computer support say "We do not offer this service". However they also say "The simplest way to do what you are asking is to install an ssh server on your actual workstation".I have done this, and it the openssh server is working because I can test from my workstation by doing ssh user@hostname and it works.What I want to do however, is to connect from outside the network. Firstly, is this possible, and secondly, what is the syntax for ssh in order to do it.
