Ubuntu :: Is Remote Development Over VNC Using Local Devices Possible
May 12, 2011
I'm looking to convert my HTPC into a remote android dev server for my girlfriend and myself, however I want to make sure that it is possible to do what I am looking to do.Is it possible to map local devices to the VNC server (such as an android phone) so that we can work on development over VNC with phones we have on our client computers? I know its a trivial matter to map local drives over VNC, but what about non-HD devices, can I still maintain full functionality as if the device itself was plugged directly into the server?'ll be installing ubuntu again this weekend, never got around to it after my last HD failure.

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

So I have apache running on my local computer. When I open up local development sites in tabs in my browser, apache threads are started. That's as it should be. However, when I close the tabs, close the browsers, and then run system monitor/system task manager, I get a long list of apache threads that are sleeping, waiting around for god knows what. How do I get these apache threads to stop hanging around?

I'm trying to make a local package server for my offline development network. Can anyone recommend a mirror containing every single package for CentOS 5.4 x86 as well as 64 bit? I've looked around but I haven't had too much luck yet.

how to setup a local mail server for internal testing on my php development work. For example if I sent an email using php script to [url]....I should be able to check the mailbox of 'someone' either in Outlook or SquirrelMail.I have done some reading about this. All I know is that I need Postfix with Courier. But I just don't know to get it working.

In my home network, My Ubuntu 10.04 LTS (fully up to date) is having trouble being able to ping other computers by their computer names instead of by their IP#s. I've checked over the settings of the router (D-Link that provides wired and wireless connectivity, DNS, Gateway, etc.) and I'm pretty sure it is set correctly. My Ubuntu system is a dual-boot (Ubuntu and XP), the other computers are all XP except for one which is running Windows 2000 Pro. All the other computers are able to ping each other by name, and can ping this one by name when it's in XP or when it's in Ubuntu.
But this computer (when in Ubuntu) cannot seem to ping the other computers by name. Some it can be pinged by name from the Ubuntu system if I include the .local to the name, but others do not. I have checked and compared the network settings on each of the computers to make sure they were set identically (only the computer name is different). All of the XP systems are DHCP configured, The Win2000 is set static and is also reserved at the router. NONE of them have any of the computers listed in a hosts file. I want to avoid editing hosts files if I can.
There are seven computers in all. Only the Ubuntu has difficulty pinging other computers by name. What should I check? What can I set? I would like to know what it is that I'm missing.

I've setup openVPN using bridging following these guides
[URL]
I'm running Ubuntu Server 10.10 My clients can connect and get their own IP within my ip range (192.168.1.x) They can ping each other and I've tested I can use the connection a lan game and a windows RDP connection. The problem is I cannot access any of the actual local network devices except the vpnServer. Is their something else that needs to be done to allow full network access?

Up until yesterday I was able to access these devices through the web interfaces that they use. I'm running Ubuntu Karmic 9.10 I have 3 PCs running on my network, and 2 NAS devices: Ubuntu (main computer, also has an XP partition)) - static IP 192.168.1.30 Ubuntu netbook - DHCP IP Windows XP (HTPC) - static 192.168.1.50 Linksys NSLU2 (was running Debian, problem arose when trying different configuration, now back to stock firmware) - static IP 192.168.1.100 Dlink DSM-G600 - static IP 192.168.1.120
I used to be able to able access these just fine using my main Ubuntu setup. Now, it will no longer display the pages. Internet access is fine, i can even access my DSL/Router device's internal config page. The netbook and the Windows HTPC can both log into these devices, as well as the XP partition of the Ubuntu system. I have tried using a VM of XP within Ubuntu, bridging the network device, i have the same symptoms - internet is fine, cannot access local network web-logins.
Access to fileshares among all machines remains unchanged. another odd behavior is that i can SSH into the NSLU2 device from all the machines, but i get odd things from this computer - it will let me log in, asks for a username and pass, but if i run anything like mc or htop, it just blanks the terminal in an odd way. from other computers the login and display are fine.

I was wondering if you can 'share' devices in Linux by overlaying the devices nodes? For instance, is it possible to use SSH (FS) + bind to selectively bind devices locally?

When I scan the blue led comes on solid and goes back to blinking afterwords but nothing is found. I did try another adapter and the bluetooth worked. BTW The Bluedevel application is real nice and works much better then the kdebluetooth app,

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.

I have Ubuntu 10.04 (fresh install) and it is my work computer/Server and i'd like access to this PC from my home. But with Remote Desktop it only says i can do local.
I've look around and opened up port 5900 in my router. Set this IP to to static and forwarded the port to this computer.
I've read that unchecking the "configure network automatically to accept connections" as it seems to cause an issue in ports i've read. Still nothing.
Here is a screen cap of my settings

I have a remote drive mounted on my system(ubuntu 10.04 x64), and i have the contents of that drive backed up to dropbox. the problem is, if i unmount the drive, the files disappear from dropbox. is there a way to mirror the contents of the network drive to a localfolder(preferably in such a way that all changes and file deletions are changed on the local folder instantly, but unmounting doesn't delete it all)? It looks like rsync would work, but im not sure how to make it work.

I want to have a script that pull db from remote server to my local. Beside that the filename should contain current date the time the db was dumped.
Ex: getdb databaseName
Then the filename should be like this:
So basically I have an archive of DB. Similar to this I need also a script that pull directory from remote to my local.
Ex: getdir htdocs
Then the filename should be like this:

I'm trying to rsync a folder(and all subfolders) down to a local directory, upon completion I'd like the remote folder to be deleted.
What I've come up with is
Code:
rsync -rvtW --remove-sent-files -e ssh user@example.com:/remote/folder /local/folder
What this is doing is simply wiping the remote files within folders(not the folders themselves) and not actually syncing anything down to my local folder(as in no files at all on my /local/folder)

I have the need to SSH into a Slackware 12 box to provide remote support. I got this, but it doesn't provide for a real 2-way communication.
while : ;
do read -p "Enter text to Local: " TXT ;
DISPLAY=:0 Kdialog --inputbox "$TXT" ;
done
So this loops and all, but it doesn't have a history and I have to wait for a return from the Local operator. If the operator has changed focus I can be waiting all day for a response and I would have to start another session to post a second comment.
What is nice is that it's small and I can create the .sh when I remote in.
-----Update since I started
I now have two scripts to take over from the first one. I have to have 4 SSH running to get this to work.
1 SSH to move(archive) and create a chat.txt; it also fires off a .sh that fires off a console that tails a chat.txt so the operator can see the chat history
2nd SSH to fire off a .sh that loops a Local kdialog input box that appends the chat.txt 3rd SSH to tail -f the chat.txt file on the remote so I can see the chat history 4th SSH to loop a read -p on the SSH so I can append the chat.txt

I am trying to stream audio from one machine to several others via pulseaudio.
Following a bit of digging, I configured the "sender" with:
load-module module-null-sink sink_name=rtp
load-module module-rtp-send source=rtp.monitor rate=48000 channels=2 format=s16be
..and the "listeners" with: load-module module-rtp-recv
Then, playing on the sender, and using PulseAudio Volume Control /Playback to set "Null Output", my listeners all start working as expected. The outstanding problem is that the sender is silent - nothing from its speakers. Perhaps not surprising after the "Null" setting above.
Is it possible to stream like this and also listen on the sender at the same time -

As many developers probably do, I have a Windows based machine on which I run XAMPP locally to test my code and a Linux machine with Fedora as my remote server.As I sometimes use .htaccess as a way to authenticate some parts of the website, I end up having two .htaccess files: one with the local path (something line D:My_Webs) and one with my remote path (something like /var/www/html/) to the password file.I have searched high and low, but I cannot seem to find any trick so that I only have to maintain one version of the .htaccess file which can work on both Linux and on Windows machines.

my local box is centos 5.5 running gnome.
I have a eucalyptus instance (vm) running an older version of centos (5.3?). As a vm it has no graphical display. I'd like to run a graphical app there so that it displays back on my local machine.
Used xhost locally and it shows the remote IP (eucalyptus instance) as enabled. On the remote side (eucalyptus instance) I set DISPLAY with:
export DISPLAY xx.xx.xx.xx:0.0
where xx.xx.xx.xx is my local ip address. Oh, I did install X in the vm instance (yum groupinstall "X Window System"). X is installed but not running there (does the point of origin of the x app need to have X running as well - and what does this mean in a vm which is a non-graphicla environment?).
Anyway, I try to run (from remote to local) xclock and get the typical
Error: Can't open display.

I would like to experiment a "green" idea of virtual desktop where multiple users are served by a single powerful machine.
I have a server running 24/7. The monitor of this machine is turned off most of the time and the OS is on the login screen.
Other users, in the same local network, use less powerful machines, which could be a thin client or an old Pentium 3 machine. They access their accounts remotely and work with the GUI as if they were sitting in front of the server. Each user sees their own desktop (different themes, screen resolution, etc.). And of course it can happen that several users could log in at the same time.
The usage is modest: mostly web browsing and the usual default applications (office, wine, gimp, etc.). In particular no games or any demanding applications. The users want to use their desktop in graphical mode only.
Question: How do we call this way of using a server? Is it possible with Ubuntu? And how to implement it?

I have a fast computer in my office and I want the person using the slow computer in the same office to boot up and see the login window (gdm) and log-in from there into the fast computer and be able to use their session on the fast computer the same time I am locally logged in to the fast computer as a different user and session.Is this best done through XDMCP? Where is a good tutorial on how to set this up?

Is there any software that will do full mirroring between a local and a remote file system. I have a server (9.04) and a laptop (9.10). Each user has shared a shared directory on the server, and on the laptop. Updates to files may be done on either system. I want to keep both copies syncronised. Currently I use a script based on rsync (scheduled by cron) to keep the local and remote copies in sync.
The problem with this approach is that rsync only seems to be able to handle deletion of files if one file system is the master, which is not the case in my set-up. If I move a file to a different directory, rsync will reinstate the old file as well as copying the new one. I was hoping there was some software that could do proper mirroring between the 2 systems, but6 so far I cannot find anything.

I have a Ubuntu server hosted on Amazon EC2. I need to create an automated backup scheme so I created another Ubuntu instance on my local network which is hosted in a virtual environment. I managed to transfer the necessary files between 2 machines on the same network using the rsync command:
rsync -azvv -e ssh /home/path/folder1/ remoteuser@remotehost.remotedomain:/home/path/folder2
How can I do the same thing but transferring files from my Amazon server to my local server? Is there a way I can achieve this with port forwarding, or by VPN, or anything else? It doesn't have to be rsync. If you know about a better method, kindly let me know.

I know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:
1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.
What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.
