When I SSH another machine and try to execute some GUI app, it does. But when I try to execute some app as root on a remote PC, it doesn't do and says:Code:X11 connection rejected because of wrong authentication.some-GUI-app]: Cannot open display:How do I make it work?

On my ubuntu I have a command pm-suspend, which puts the computer to sleep. It has to be run with sudo. Since it is inconvenient to be forced to type the password every time I want my computer to sleep, I thought maybe there's a way around it. Naively I thought that if I'd create a script as root, that invokes pm-suspend, and then let anyone execute that script, I could run that script as my own user and then that script would be considered run by root and hence be allowed to run pm-suspend. Obviously that didn't work. The root-check procedure in pm-suspend still found out that the original executor was someone different from root.
Still I think something similar (although slightly more elaborate) should work.I'm thinking about the process that allows the user to mount hard drives for example. Normally root is required, but it is somehow bypassed by the gnome utility mounting.
I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?
View 1 Replies View RelatedI downloaded a program called tonespace http://www.mucoder.net/en/tonespace/ which I extracted and then tried to execute the executable file with ./tonespace. This gives me the following message:
bash: ./tonespace: No such file or directory
When I use the command: file ./tonespace I get this: tonespace: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
I dont get it. The file is clearly there, yet when trying to execute it bash doesn't seem to recognize it.
It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?
I'm trying to get Expect to execute commands on a remote server using SSH with username/password authenticationMy current expect script is
Code:
#!/usr/bin/expect -f
spawn ssh -tq root@my_hostname "whoami"
[code]...
I can ssh to the remote computer OK, but the commands execute on the local machine, not the remote machine as they should. After much frustration I did the following hoping to clear the problem. I turned off all machines on my LAN, the hub and the router. I then rebooted everything in the reverse sequence - cable modem, router, hub, and then the computers.Then I reinstalled ssh on both machines.
sudo apt-get purge openssh-server openssh-client
sudo apt-get install openssh-server openssh-client
sshd in now running and port 22 shows on both machines. However the problem persists.
I have an immutable script on server A, it executes a maintenance command on the remote servers where elevated privileges are needed. I want the developers on server A to execute the script and run it without being prompted for a password. The script contains scp root@serverB and ssh 'root@serverB', if run as root it runs great since I am using ssh keys. However, as regular users they are prompted for a password. If I do created their group on server B...etc and give the group sudo it would still ask for passwords right? Can I overcome this?

I have been having trouble setting up a daily backup script with cron. It would basically never worked. Searched the net for answers but didn't find anything. I finally figured it out !! When root crontab is edited the execute flag is removed from #/var/spool/cron/crontabs/root. I change it with #chmod a+x /var/spool/cron/crontabs/root and all is good.

I'm connected to the internet using a wireless router. Each time I boot, I have to grant root privileges and type in a shell: iwconfig wlan0 essid linksys key dhclient wlan0 Isn't there a file(or location) that I can modify to automatically grant root privileges and execute these commands when debian starts? Something like autoexec.bat in windows.

I am running ubuntu 10.04 as a web/file server. I have set up several cron jobs in the past which until recently were executing normally. However, a few days ago, cron jobs stopped executing after a restart. I was able to fix the problem by deleting and reentering the cron jobs, but only until the next restart. ps -ef lists cron.
Summary:
1.) Cron was working --jobs executed without error and restarts worked fine
2.) Cron jobs stopped executing after a restart about a week ago --ps -e still lists cron
3.) Removing all cron jobs and reentering them by copying and pasting fixes until next restart
4.) Cron job syntax is known to be correct since they were executing before this problem arose.

I have Lynx, trying to connect to a tightvnc server on a Win7 box on my LAN.
Server IP: 192.168.1.42:5900
The remote desktop window just goes black and pops up a dialog saying connection closed every time.However VNC works fine as I installed xtightvncviewer as an alternative and that connects, and I can view the Win7 desktop and control it and do everything you would expect.
I've also tried connecting using Android VNC viewer from my phone on my LAN and that also works fine so it appears to be an issue with Remote Desktop Viewer.Incidentally using R.D.V. on Intrepid into a tightvnc server on my old XP box worked fine.
i just reported a bug to launchpad (#511562. i'm not sure if this bug is in flashplugin-installer or pulseaudio.when i use firefox or chrome for watching a flash video from videos for example, all works good. i then transfer the sound to a remote sink using sound preferences > output > internal audio analog stereo on myuser@otherhost. after this is done, the flash video halts. this is also true if i restart firefox and start a new video, already having transferred the sound. sometimes you can see the video taking huge skips forward. for example, on a 3 minute music video, i see 3-4 different frames from different places in the video. the sound is ok though! 100% reproducible and if i transfer the sound back to local speakers the video resumes and plays perfectly.
View 1 Replies View RelatedI set up a git repository on the live site of my website using git init. Then I created the same repo on my local machine using git clone command. Then I made a few changes and committed them to on my local repository. Then I tried to use git push origin alongside the ssh path to my repository on the remote machine to update my live website. However, I noticed that git-push only changes the head of my git repository on the remote machine and it doesn't change any file.
In order to update my remote repository I have to issue the following command after I use git-push.
PHP Code:
git reset --hard HEAD
This is a two-step process for committing changes to the live site. I was wondering if it's possible to merge these two steps in one to make life a little bit easier?
Note that, I'm the only one working on this project (sometimes from my laptop, sometimes from my desktop), so I trust all the commits.

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.
View 2 Replies View RelatedI've just upgraded my web/tv setup from 9.10 to lucid and everything seems to be working apart from my infra red remote control.The remote was working fine in 9.10 and was used to control mythtv-frontend however after the upgrade the remote appears to be controlling ubuntu natively, i.e. right left up and down control what is selected on the desktop where as previously the remote was set to only work within mythtv. Whilst native support for my remote control is muchly appreciated(if that is what this is) where can I configure the controls so that it is usable again?
View 1 Replies View RelatedI (finally!) have Mythtv working under 10.04. I use the Haupaugge DVB-T card with its remote. Whilst setting up the kit this worked OK. When I unplugged the keyboard and mouse the system prior to installing it next to the TV appeared to have stopped responding to the remote. In fact it seems to be responding to a number of the remote keys but not the OK and Go keys which isn't enough to run Mythtv.
I don't think leaving a keyboard & mouse plugged in is going to be domestically acceptable.

I want to set my main PC as a remote desktop so I can use it for programming and data storage remotely. I plan to control it with my netbook running Ubuntu Netbook Remix. If I disable compiz I can successfully connect and manipulate my desktop remotely, but I can't do it with compiz enabled on any settings. Is there a way to fix this issue? Would I have the same problem if I installed KDE?
