So I am seeing the below error on all of our ubuntu client logs..This is being logged on an hourly basis Though everything is working fine, I am really curious to finding the root cause for this...

First of all,let me congratulate the Ubuntu Team,Canonical and all those who toiled hard on Lucid.Its a damn good release and in my opinion, one of the best till date.If I have to rate Lucid on its...

1) OSSEC - Host Based Intrusion Detection (HIDS)

2)Logwatch - For logs monitoring & reports

3)Tiger - For intrusion detection signatures,rootkits,vulnerabilities on host level

4)SPLUNK - For...

As the other poster suggested,try changing the nameserverdirective in /etc/resolv.conf to your actual configured dns server (or) use /etc/hosts if its just couple of hosts.I am attaching a setup doc...

1)It may be an issue with the /boot/grub/menu.lst entries.Check this in the recovery mode.
2)Grub may need to be re-installed (or) /boot restored.
3)Its possible that that RAM Disk image...

Running your machine on Ubuntu Server would be a real wise decision.I have been using Ubuntu 8.10/9.04 server versions over an year and its absolutely wonderful.Package mgmt using apt-get is a breeze...

I would suggest,go through the CLAMAV manuals/tutorials for performing the basic anti-virus scans/checks.It always good to learn the command line way as you learn the inner workings of the app/system...

That did it.Installing the backports and rebooting the machine seems to have fixed the issue.Didnt have a single wifi drop this time and it was at 100% signal strength all the time unlike before.The...

Yesterday,I performed an online upgrade of my 9.04 to 9.10 and started seeing this irritating wifi issue.In my case it drops atleast once in every 10minutes and only reboot fixes it.Looks like...

What is the logic behind this rationale of not trusting ClamAV ?Because its OpenSource? If that's the case,then I am sorry to tell you that its a flawed argument.Infact,its the other way round.

Try using SPLUNK...Its an awesome solution and have been using it since last 1year...and really easy checking syslogs for a particular server..it takes care of filtering and showing you the results...

NSA invented SELinux and it was incorporated into the linux kernel..Especially RHEL as other posters rightly pointed out..Using RHEL is the right thing to do in those Orgs...At the same time, IMHO...

Hmm!Strange...How would a OS boot itself?My best guess would be either a Wake on lan enabled lan card (or) a power fluctuation.Some machines when you plug the power cord into them,they power up.This...

Thanks for the correction.My bad!You are right.It will basically let the person initiate a connection,but then will go ahead and reject/refuse it.

This is how my setup is.As mentioned before,I configured my denyhosts to block any IP (user who enters more than twice wrong password) from even initiating connection to my server.And in parallel,I...

I think you should change the description of one of the features of samiux and not point to specific names.Else,some people who are really interested in this distro may get turned off.

"Web Filter...

I couldnt agree more!Denyhosts is a wonderful utility and it does the job perfectly.I have been using this since a long time and it never let me down.Configured it to block any IP from which any...

Ideally,if you see lot of cpu being used by hald daemon,that means its polling for some devices and on io wait.There have been instances where in killing hald or disabling some peripherals which are...

hald is hardly taking 4% cpu...this is not abnormal..at the same time we cannot conclude anything from one iteration of this output.Can you try killing the hald pid and see what happens.Make sure you...

Can you paste the output of the below commands:

top

iostat -d 10

sar 5 10

Do you see lot of cpu for the gui in top?

When you say external drive,how exactly is it connected to the system?Using firewire or usb or a usb-sata docking station?And does your main /boot and / partition reside on the external drive?
...

It may look good on the paper.But,in reality the scene maybe completely otherwise.My best guess is there maybe real latency due to IO limitations considering that it has a single sata drive assuming...

All I am trying to say is any OS needs time to evolve.Linux is at a crucial point in terms of its adaption in desktop market.Funnily,your analogy reminds me of Creationists comparing Evolution Theory...

Exactly!!!! This is what exactly I did with my older Dell Laptop after I got a new laptop.I installed Ubuntu 9.04 Desktop edition,installed all media codecs,installed crossover,IE7 & MS Office 2007...

You are completely missing the point.Give Linux some time to evolve and improve.ROME wasnt built in a day and neither did Windows 7 pop out of nothing.It took almost 6 iterations & 20 years to come...
