Ubuntu Servers :: Get Notices That There Are Updates For The Server Software From Time To Time?

Mar 29, 2010

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.

Ubuntu Servers :: System Time Runs Slow Hareware Time Run Right?

Apr 11, 2011

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:

hwclock --hctosys

I want to run a crontab to have that command run every minute. But it don't seem to run.

Ubuntu Servers :: Setup Real-time (or Near Real-time) Folder Synchronization Among 2+ Servers

Mar 23, 2010

what the recommended way to set up real-time (or near real-time) folder synchronization among 2+ servers. I looked a rsync but that doesn't sound real-time and it looks like its something that you might put in a cron once an hour.

CentOS 5 Server :: Time On Xen VM's Drifting Ahead Of Real Time?

Aug 4, 2009

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

Ubuntu Servers :: Server Time Off By An Hour

Aug 31, 2010

Recently moved into amazon's ec2 cloud and noticed our server time was in UTC where we use EST. I did some looking around, and changed using the following;

Followed up setting the correct time using the date command with the correct time, then date showed;

Now, that is correct, but if I do an ntpdate pool.time.org or any other time server, the offset is huge and the date moves back one hour. Is this a daylight settings or something I am just missing?

Ubuntu Servers :: Web Server Time Freeze And Weird Load Avg Data?

Aug 23, 2010

I am completely stumped. Found my web server (lighttpd) unresponsive this morning and had to hard cycle it. After some cleaning up, all was happy. However, after about an hour of handling a decent amount of web traffic, time freezes as far as the web server is concerned. I've got an hour of access.log data with the following date: [23/Aug/2010:20:42:58 -0500]

It never changes. The load average now reads 0.00 0.00 0.00 (which is totally inaccurate). And I am not able to successfully log in remotely. I have taken the server down 3 or 4 times today and after an hour or so of functioning normally, this is what happens. Additionally, the local time is now off by 30 minutes.Trying to force with ntpdate does nothing (or, at the very least, sets it to the same incorrect time)

Servers :: Ubuntu 10.4 Server Stops Accepting Connections After A Period Of Time / Fix It?

Apr 24, 2011

I'm not sure if this belongs in the Server or Networking section of the forums. Anyway, last month I upgraded my server to Ubuntu 10.04 LTS. Since then, I've had a recurring problem wherein after a certain period of time, the server stops accepting network connections. Ubuntu 10 will continue to reject network connections until someone logs into the server locally, after which time network connectivity is restored and the cycle begins anew. Essentially, the server goes into a "half sleep mode". I say half because the computer is still on and the fans are running.

I've done some searching around various forms and initially figured this issue was related to problems with the Network Manager service (https://bugs.launchpad.net/ubuntu/lu...er/+bug/524454), so I removed the service altogether. However, this problem is still occurring.

I've poured over /var/log/messages and /var/log/syslog, but have noticed no irregular behavior. Has anyone else experienced this issues? I'd rather not resort to downgrading back to Gusty Gibbon if I can help it.

I am happy to provide more information if its needed

Server :: Ntpd - Time Server - Not Time Source ?

Jul 14, 2011

I have a set of machines on a disconnected network. Periodically, one of the machines connects to the internet and synchronizes its time with a time server that is not known until the connection is established. (The machine queries a central command server for the address of the time server it should synchronize to.)

I then use a custom tool to do some calculations to call adjtimex() and adjust the clock so that it runs fairly accurately.

I know ntpd is supposed to be able to handle disconnected networks but I thought you had to preconfigure the servers in the configuration file.

My intent is to run ntpd on this machine (without configured "server"s) so that it can serve time to the internal network. (Periodic synchronization using ntpdate from the internal machine to the bridge machine.)

The problem: ntpd wants to fuss with the values I set using adjtimex(). I want it to quit thinking it needs to adjust the clock and just serve time to the internal network. (Maybe I have a GPS time source hooked directly to the machine!)

Ubuntu Installation :: Schedule Updates For A Certain Time Of Day?

Sep 1, 2011

My Internet service provider here in South Africa is Vodacom (Vodafone) and I pay a huge amount of cash for 2.5Gigs per month. They do, however, give me the same amount of data for free that I can make use of between midnight and 5.00am.For this reason, I would like to be able to schedule my update manager to download all updates at, say, 10 past midnight.Can any of you guys out there offer any suggestions or is there a way that we can make a request for the Ubuntu developers to include this in "Update Manager"?

Ubuntu Installation :: GDM Taking Long Time To Come Up After Updates?

Mar 26, 2010

I have just made a clean install of Ubuntu 9.10 and after installing all updates, GDM is taking a long time (about one minute) to come up after a clean boot, resulting in a regular console prompt.

If I issue "sudo service gdm start" it does come up promptly.

What can I do? Where can I see startup logs to try and identify any problems?

Ubuntu :: Schedule Unattended Updates To Install At A Specific Time?

Dec 8, 2010

I've been quite puzzled by the behavior of unattended updates - it seems it runs the updates at or before 7am (on all the server installs I've got). They are only set to do security updates unattended, but what I am wondering is if there is a way to change the time that they install? I want the updates to install early in the morning, at like 3am or such, so I can reboot the machine when I get up if needs a reboot.I found a few mentions about it, but nothing specifically talking about the time.[URL]..

General :: Install Guest Additions Over Again Every Time Kernel Updates

Aug 19, 2010

I have Ubuntu running as a Virtualbox, and every time it upgrades the kernel, the Guest Additions stop working.The install process in Linux requires using a virtual CD, running scripts from the command line, etc.Is there any way to keep the guest additions constantly working even when the kernel is upgraded? Can they be installed as Ubuntu packages instead of installing off the virtual CD?

Debian :: Apt-get Updates Waste Time Requiring Re-scanning Dvds

Mar 6, 2011

I have the eight Debian dvds listed in my sources.list, along with security, nonfree, and multimedia repositories. It does this for all eight dvds, re-scanning them for the update.These dvds have already been scanned (from the apt-cdrom add command). New updates are NOT going to suddenly appear on these already scanned dvds, so this is a completely unnecessary endeavour.Is there a way to stop this?It didn't happen with Lenny, and I'd like to stop it with Squeeze.

Ubuntu :: After Log In Takes Long Time To Show Desktop, Monitor Events At Log In Time?

May 24, 2011

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 want to have a terminal open and have something like a "repeating cat" command running in it for a certain text file (in particular /var/log/system.log). So my terminal will scan or cat the text file every so often or whenever the text file system.log gets written to by the system, it will display whatever it wrote to the file in my terminal that is open.

Ubuntu :: Screen / Everything Freezes From Time To Time For No Reason In Natty?

May 4, 2011

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.

Mar 2, 2011

I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?
