There are many time zone files accessible from the command line that don'thow up in the GUI ("system-config-time"). How do I add these time zones to the GUI
This is actually in a time format(hh:mm:ss) and how do i add all the values and get the sum in seconds . the output should be in seconds like total number of seconds : 241 secs
I've just installed Ubuntu 10.04 and find that if I leave the machine for more than a couple minutes, it will automatically log me out. Instructions at other sites have indicated that session controls are to be found in System>Properties. But there is no Session in the list under Properties in Ubuntu 10.04. How can I control this feature so that I'm not having to constantly login every time I turn around? I've searched everywhere and can't find a solution.
When I installed CentOS, I forgot to modify the settings of Network Time Protocol. I need to do the following: 1. Enable Network Time Protocol. 2. Add a new ntp server to the list. How I can do this after the installation. Is there an utility to handle this? or do I need to modify any files manually?
I just set up denyhosts and it worked properly the first time adding lots of ips to the hosts.deny.I then set it to run every 12 hours noon and midnight.I wanted to see if ran properly and I got all this.Does it look like its working?
When I search addons with firefox, it takes 4 mins to connect to server, and after approving to ad it, it again takes that much time to connect to download. While downloading it's ok, but connecting to server takes time. This is for all addons. Is there any body having same issue?
My ISP offers the service of native IPv6. So my ADSL router provides me with a local and global IPv6 address. However after a reboot it takes minutes to finally see the global address when using "ifconfog eth0". During that time I can't do a ping6 to an external server, which seems logical. So I waited several minutes, but no global address. After that I started a KDE session, went back to the console(<Ctrl>+<Alt>+F1) and now the global address was there. Is this normal behavior or should I file bug report?
example:I block my desktop in gnome, what happens first? what programs run and how i can configure the behavior?If screen-saver is running, how i can run a "background" process that can count the time the session have blocked?How i can run programs when returning from screen-saver?I know that all depends on the desktop environmenl and the screen-saver used, but i want to know all the "bloodie" details behind.
Is there a session manager I can use with 10.10? I would like to try Openbox but am not sure how to select it as a startup session. I would like to be able to choose between kde, gnome and openbox.
I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.
I am putting together some new systems for my customer and I'm having some trouble with a script that we use to back up files to a DVD R. The problem is that I can't write a 2nd session to the DVD unless I eject the disk and reload it. The drives are slimline type drives, Sony BD-5730S and Teac DV-W28S-V93, so they won't reload without human intervention. Opsys is CentOS 5.4 or RHEL 5.4. I've tried both AMD and Intel based mother boards. If i try this on Fedora 11 or 12 it works fine. This works on IDE attached drives but not a SATA attached drives. Fedora appears to use something called genisoimage instead of mkisofs. I can't get genisoimage to run on CentOS or RHEL.
Here's the code to setup the test files:
rm -f /tmp/BDtest/* mkdir /tmp/BDtest dd if=/dev/zero of=/tmp/BDtest/blank.iso bs=10M count=1 for NUM in {1..160}
I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
The following message comes up when I boot up: Logging in user Warning: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0. When I press OK, the system completes the start up and everything looks normal. But when I try to connect to internet, I get the following message:
KNetworkManager cannot start because the installation is misconfigured. System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution. KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.
Don't know what info is of interest. I'm using
Opensuse 11.2 KDE 4.4.2 (Factory) After upgrade from 4.4.1 to 4.4.2 it worked fine for a week or so.
I do a clean install of slackware64 13.1 beta1 with KDE and switch default runlevel to 4 in /etc/inittab.
I try to login in kdm, I always come back to the login....
I try this with default runlevel 3 and an .xinitrc with "ck-launch-session startkde" .. works without problems, so I switch back to default runlevel 4, now i can login and only get the error "Cannot open ConsoleKit session: Unable to open session..."
It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?
I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.
I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code: hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.
For like windows you can resore your os to a state of peace kind of. If you messed up your vital files you could go back in time and restore you computer to a selected time. I was wondering if you could do that for ubuntu
Ever since I installed Ubuntu Natty, from time to time, for no particular reason, the entire computer screen freezes, and I am forced to hold the power button on my laptop to restart things with a hard reset. I cannot explain why it happens.
Such an issue never occurred in any of the past installations and versions of Ubuntu. This is a fresh installation of Natty by the way.
Also, I can currently be running a lot or nothing and it does this. Thus, it does not matter what I am actually doing (ie, what programs I might be running).
It has occurred about 10 times since I freshly installed Natty 6 days ago.
I started out with Kubuntu RC, then installed ubuntu-desktop and updated all the way to the current state of packages.Anyway, from the moment I installed the RC, from time to time the boot splash appears, the dots light up/turn off and then the booting hags. No key seems to work.I the do a hard reset and everything works just fine.As not to open another thread:- how can I see the Ubuntu splash screen? (currently I can see the Kubuntu one)- how can I turn the splash off and have it boot in text mode?
When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.
