We have just installed VNC. It seems to work fine. If we connect to a remote system using VNC, on say DISPLAY 5, it works and we can run our applications. If another person wants to view this session, they can also connect to DISPLAY 5, and it is fine.
However, if you are just sitting at your own system, without using VNC, and someone connects to your system using VNC to DISPLAY 0, so you can show them what you are doing, they do not see your session, they see a plain startup session, not the session in which you are running your applications... How do you let VNC users see your normal non-VNC session? Have I configured something wrongly? We are new to VNC!
I have created 2 users and changed their secondary group to grp1, then changed permission for a directory dir1 to 770(no permission for others) and group to grp1.
The both normal users are not able to access dir1. How is it possible to access that Dir using general permission (770).

View 3 Replies View RelatedI have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)
I write a little script that run top command and clear the output leaving only cpu ram and swap values. If i run the script manually everityng works fine but when i schedule the cript to run every 5 minutes from /etc/crontab all run fine but the output of the top command doesnt appear in the log :

I read one release goal for wheezy which I had read few days ago, dnssec for wheezy.

Now the only thing I understood is this will make it harder for the bad guys to give any fake packages while I'm updating from a debian mirror .
Am I correct in assuming that ?
Also do I just have to install the autotrust package and wait for the dnssec-conf to be packaged and installed, correct ?
As per subject, what's the best way to run a CRON job for something that "normal" users need to run as SUDO? There is a problem with the internal clock on my PC so at a regular time (every hour or day for example) I want to sync with my Network Time server. I use "sudo ntpdate time.bgr.local" as it is now and have to enter my user's password for it to work.I know root is disabled by default and would like to keep it that way if possible but if I have to enable it and then add it to root's cron list the so be it but would prefer not to.
View 5 Replies View RelatedI have Lucid lynx on my laptop, its been working perfectly for months. Recently been trying to get flash videos on sites to play and came across a 'fix' that said to disable desktop effects, which I did.
That didn't work and afterward found out that adobe flash 10 don't work on 64-bit linux, which is what I have. Tried to re-enable desktop effects to normal but got "cannot load desktop effects" popup.
I've removed nvidia driver, reinstall it, tried to enable desktop effects, didn't work. Ran nvidia-settings which said to run as root nvidia-xconfig and restart X(alt-printscr-k), which I did, it didn't work. I just want my desktop effects back, I had it on extra.
Edit: Forgot to mention that at boot, after grub menu nothing shows. No login screen. I have to add "nomodeset" by pressing e at boot menu and typing it to the boot options to get a dialog to choose restart x which then shows the login screen.
Update: I've been searching all over, tried to install by downloading from nvidia site, didn't work, been rebooting like crazy after every try. Installed a bunch of nvidia files from software center and got hardware drivers to have nvidia current. The driver is activated and in use. However I still can't enable desktop effects and ubuntu doesn't boot normally. After the grub menu it shows the logo for a second then blank screen. I have to boot with nomodeset and choose to restart x or start in low graphics mode.
Please help me fix this.

View 9 Replies View RelatedI have shared two external harddrives via samba on ubuntu, but only I can access it. The reason being is because I have logged into linux, and become the owner of the external hdd's. On the permission properties, I can see that the group I have created every other user under has "No Folder Access", and if I change this it reverts back instantly. So frustrating, I've tried to chmod it which hasn't done a thing. The owner of the external hdd's seems to be the only person who can access it over samba.Is there anyway I can get normal users to just read and write to external hdd's?

Here's what I want to do: install ubuntu on a laptop and then create a normal user so that the user could install the normal upgrades without using the root account (or getting root privileges via sudo).
I know that this can be done by adding the user to the admin group, but this has (at least) two bad side effects:
1. The user can use sudo to gain root access. (And then do everything: install or remove programs...)
2. The update-manager doesn't seem to appear in the panel. (In stead it opens in the background.)
I could easily make a script that downloads and installs the upgrades automaticly, but I'd like to give the user a chance to choose when to do all this. So that it's not done for example when the user is using slow mobile connection.

Code:
works fine. On Fedora I can get into the directory with Nautilus and have read/write permissions as specified in /etc/exports on the server, but on Ubuntu I can only get into it from a sudo'd command line.
The ownership of the file on Fedora is "nobody" and on Ubuntu it's "user #500", with only people in the "500" group having access to it.
Obviously the permissions can't be changed on the client, but with the Fedora box being able to read/write to it with no problems I'm not sure what else I can do on the server to let normal users on the Ubuntu box read it.
