Networking :: Remotely Login To Remotely Display Data?
Jun 29, 2011
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!

I usually remotely connect to a client server to make adjustment via the CLI.Occasionally I have to login into the desktop to understand some issues that my customer are trying to explain via Vino-Server. I have notice that sometimes when I attempt to login via ssh, I sometimes can see that a user has not logged into the GUI desktop which means that I cannot login into the remote desktop session to resolve any issues via the GUI. My question is:How can I remotely login via ssh and start a gnome or kde session for the user account that I am trying to resolve his or her issue?

Does anyone know or recommend some software or a script to remotely power on a PC from standby to on, or even better from completely off?
I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)

Problem : centos 5.3 hangs while remotely copying data onto this server.
I have A centos 5.3 x86 Version installed on Xeon Quad core , running on 8 GB DDR2 RAM, RAID 1 confgured on SATA drives. this was old installation copy and It has many more things running on it.Therfore, I can't just reinstall it.
I have setup SAMBA PDC + ldap on it. I encounter that system hangs when I copy data into this server from LAN computers.
My troubleshooting steps :
1. I have checked for network issue , My network works fine when I transfer data between other LAN compuers.
2. Even I have tried confguring seprate LAN....
3. I thought their might be some problem with my SAMBA configuration, therefore I did data transfer from sftp .

I installed CentOS 5.2 and then run yum update. I configured this server as LDAP/Samba primary domain controller. LDAP seems to be OK and for testing I am able to create users with:smbldap-tools useradd -am usernameI can ssh into the server as root and also as a Linux user which was locally created in the server. But ssh into the server as LDAP user fails (from a Fedora 11 machine) with "Permission denied, please try again", prompting again for password.Some data:
# rpm -qa | grep ldap
python-ldap-2.2.0-2.1
php-ldap-5.1.6-23.2.el5_3

I am running NFS and NIS servers in my FC8. Clients are also running FC8. Everything was working fine. I could login remotely to server as well as clients. Suddenly (few days ago) a problem started. I can not login remotely to client machines. I did not do anything. I can login to server remotely, but not the client. When I try to login, it accept password and nothing happens. Also, when I try to login from server to client same thing happens. We share the home directory of the server with client. Another question: there two type of nfs server nfs-user-server and nfs-kernel-server. I just use gui to set up the NFS. I don't know which one I am running. Is there any way to find out which nfs I am running?

there is a way to set an ip address on a computer remotely. Here's my issue : Have a debian computer (plug computer) on which, after upgrade, i m not able to log in back anymore. At the moment it seems i have no chanche to connect something like a monitor but i m pretty sure the computer it boots up cause wireless is on and i can see ssid and mac address of the ap.
I ve tried to assign an ip to the mac address (from my laptop) by arp and in the table it shows the link between the mac and ip, but i m unable to ping the ip after that. I was trying to think of maybe set up a dhcp server from my laptop and see if the plugcomputer gets an ip automatically, but i m not sure if it is working and at the moment i have little experience on set up a dhcp server on linux (sabayon). Do you think is it possible to manage the network card of my plug computer by eth/wlan from my laptop?

I'm running Ubuntu server. To change the IP while I'm sitting in front of the computer, I would:
1. edit /etc/network/interfaces
2. ifdown eth0
3. ifup eth0
Remotely, I can do the first two no problem, but the ifup command causes some problems since the ethernet interface is no longer functioning. Is there some kind of script that can be written for this purpose? Maybe something that will check eth0 every so often and make sure it is running and bring it up if it isn't. Or else a script run with nohup?
I do not intend that changing the IP address will be a frequent occurrence, but when it needs to be done, it must be done reliably and without the possibility that the computer will no longer be reachable for more than a couple minutes or so.

Just throwing in a quick question to see if anyone got any ideas about this.I'm unable to create a remote X session with TightVNC viewer. The local computer is a windows XP box and the remote server is running Slackware 13.
Using Putty on the XP box to connect to Xvnc through a ssh tunnel works just fine. However, when I fire up TightVNC viewer and try to connect to 127.0.0.1 as I'm used to, TightVNC viewer is unable to establish a connection to X. I'm puzzled.
This has worked when I used another XP box as local computer. I'm running all within my LAN. Can this be a firewall/iptables issue? I've obviously posted this in wrong forum category. Sorry about that. Starts this thread in server category too.

I have two machines. Desktop and X61s. I have a drive on Desktop called Ianthe. This is in /media. This is remotely mounted on my X61s machine (a laptop), as /media/Ianthe. It automounts when I boot it up. BUT, the same drive looks different when viewed on the remote machine. An example is a certain directory, which when viewed on Desktop has 21 files in it, but when viewed on X61s has on 7 files in it.
If, on the X61s machine, I go to Network > Windows Network > LBBARNET > DESKTOP > Ianthe and navigate to the relevant folder, I can see all 21 items. But if I mount it, I can only see the 7. I have tried rebooting X61s, but it remains the same. The permissions on all the files in the folder on Desktop are identical, so I can't see any permission reason why this should happen. And, if I copy one of the files on the Desktop which doesn't appear on mounted view on X61s then the copied version appears immediately on both views.
fstab on Desktop
Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

I've got a problem about how to map or mount the whole developing environment remotely?
For example,There is a server A (CentOS) which I have got a normal user name and password but no root control.And my desktop B (Opensuse) which I've got the root authority.Normally, when I do some software developing, I use SSH to login to A. All the developing environment are installed on A, e.g. libraries, PATH, makefile, etc.However, there is a waste of my machine B, because all the test, debugging are performed on A.
I know that sshfs can map a path to local remotely. May I ask if there is a method to map or mount the whole working environment from A to B please?

*Solved* I have been reading the following guide on how to use the VNC programs and a GUI to connect to my main machine from my laptop via my LAN and router:
[URL]
This allows me to control the server remotely, and run applications on the server remotely, with the GUI output being shown on my laptop, which is really neat I had Eclipse + PDT running on my server and had to stop it and start a new instance remotely from the laptop via VNC viewer, as Eclipse said the workspace I wanted to use was already in use.
So starting the VNC server on the main machine does not allow me to access the programs that are already running on the main machine under the native X server. However I can now do PHP debugging remotely using Eclipse + PDT now, and all the PHP source code is on the server machine. That's OK, but I would like to do more than that. I want to be able to connect to the native X server on my main machine, and control all the applications running on the main machine remotely from my laptop, without having to shut them down and restart them again via a VNC viewer.
Is there some sort of remote control program I can use to allow me to connect to the running X server on my main machine from my laptop, and control those applications remotely please, so the desktop layout on the main machine's screen is mirrored on the laptop screen?

I have a computer (C1) to which I can connect through the Internet (ssh, for instance) (it has a static ip and though it is sitting behind a router, the appropriate ports are all forwarded). I have another computer (C2) that doesn't have a fixed ip address and sits behind a router that I cannot fiddle with (so no port forwarding here). I would like to know if there is any way to connect from C2 to C1 such that a directory on C2 would be mounted on C1.

I'm trying to set up an SSH connection from my school to my home, but not on port 22. I originally tried port 2222, but it didn't work. I called my school IT people and they said they block that port. I asked if they care if I set up an SSH and they said no, but that they wouldn't tell me which ports are blocked and which are open for "security" reasons (which I guess I can actually understand). They suggested just using port 22 or 222, but said if a ports open I can use it.
My question is, can I check ports without setting up SSH? It seems like a hassle to try a different port every day on my home SSHD file, come to school, see if it works and repeat. Is there a way I can check my computer home for connections that could connect, even if there isn't a service listening? I don't know how to do that, or even if its possible. If not, I suspect I'll just try a few until I find something that works, or just go ahead and use 22.

My work uses an internal software suite where the data is hosted with a linux server. It uses mysql and samba shares. We are currently opening a new location and need to be able to access the samba shares. We are able to access the mysql databases. The samba shares are used to store various files for the software such as updates, invoices (as pdf files), etc. I've setup vpn connections using windows servers in the past but I can't, for the life of me, get a VPN server setup on our linux server that windows will connect to. I've tried openvpn and pptp. I'd prefer to use the built in windows client to connect.

I am trying to setup the most efficient way to remotely administer an ubuntu system. So far I was successful in setting up ssh. I have the server running and made sure it only uses keys to authenticate and changed the default port. I can connect to the ssh-server. This system is behind nat and bots trying to break-in when I forwarded the port. I used the AllowUsers option, which helped in knocking back these rouge connections. I was not comfortable leaving a port open all the time, so I set up logmein Hamachi VPN and closed the ports that were open on NAT.
Now I use Hamachi and am very impressed. I use VNC in VPN. But Vino is slow, I tested x11vnc and it was slightly faster. I also tried to set up freenx but nxsetup file was missing. some one posted that file in the forums and suggested copying to the system but I was not sure if I want to download a script from the forum and use it. So for the time being, I thought I will just concentrate on X11vnc until freenx is fixed.
I would like to create a separate desktop on the server and use it to access remotely. This way we will not have to fight over the cursor (sounds funny but very frustrating). From what I understand x11vnc has this function inbuilt (uses vncserver). I cannot get it to work! when using ssh, at the remote machine's command prompt, if I type "evince xyz.pdf", it does not launch the "xyz.pdf". what am I doing wrong? When using VNC, how can I change between different users on the remote machines? Right now I can only use VNC in one account that I first setup. When I try to change to another user, vnc client goes blank. How can I get as much control of the remote system as possible? Right now I need someone to switch on the remote system and login to their account before I can VNC. Can I use ekiga inside VPN, I use skype right now and it's sometimes terrible with dropouts. I looked around and someone suggested using ekiga as it works very well over lan. How do set up ekiga so that I have a direct connection with the remote system? Is there any client that just takes the IP address and creates a connection? Mumble seems to be the popular choice, it's most suited to LANparties, I just need a connection between two systems. I am trying to set this up to help users with hardly any computer knowledge to use the system without any issues.
