Ubuntu Servers :: How To Install Cetificate Authority
Aug 3, 2011
* Correct me if I am wrong.* In web browser, if I go to a SSL site, I need to install a CA from the SSL site, so the web browser trusts it.* I assume my ubuntu box is working the same way.* That is if I need to do ldap bind or search, I need to install the CA and put it in /etc/ldap/ldap.conf* It works well, if I only have 1 CA in ldap.conf. * If I put 2 CAs in ldap.conf, only the last one will work. e.g.
BASE dc=a,dc=b,dc=c,dc=d
URI ldaps://somesite.com
TLS_REQCERT demand

I just got a pop up that said that there is a Firefox Ubdate that I do not have the authority to install. It gives a link of www.firefox.com to go to for the latest firefox. I checked the Update manager. No update. All of Mozilla links in google say Mozilla. I feel sure this is an attempt to install malware. It came up when I went to cnet and I guess I shoule include a picture of it. Does anybody have any experience with this?
I went on to read cnet and the first article was about major add servers serving up adds that automaticly install malware. I guess this was a case of that. I had addblocker disabled at the time but noscript active. Looks to me like having noscript saved me an infection. Be careful out there.

I changed the user name using the User Properties window and rename the home directory with the new user name. Did not change the Group Name. The new name is ResearLab
When I restarted the system I received an error message:
Gnote Crash
gnote 0.7.3-4.fc14
Following are the messages:
(1) could not update ICE authority file/home/ResearLab/.ICE authority
There is a problem with the configuration server
(2) /usr/Libexec/gconf-Sanity-check-2 exited with status 256
(3) Nautilus could not create the following required folders: /home/ResearLab/Desktop, /home/ResearLab/.nautilus.
Before running nautilus, please create these folders or set permission such that natilus can create them.
A. What did I do wrong? Is it not possible to rename a user in Linux?
B. How can I correct this problem?
C. Should I have created a new user instead or renaming an existing one?
D. Can the primary group be renamed?

We have the same problem but tried his solution to no avail.
Doing a shh would give me an error..

When I change SElinux to permissive from enforcing I can login but turning back to enforcing, the problem comes back. I did the following...
Quote:

I've run into a problem and I don't know if it's apache or php or the combination of both. I can compile apache 2.2.15 just fine, but whenever I try to compile php 5.3.2 into my server, the first two steps work just fine but when I get to the make install part it shows the libphp5.so and it just stays there and I have to cancel the install because it won't finish.

I recently installed a Ubuntu Server 10.4 on a new machine. This I installed as a cloud node controller.
I wanted to use an existing machine running U 9.10 Desktop (which was a cloud controller, cluster controller, storage controller, and Walrus controller) in that same capacity under the newer UEC. The advertising was compelling with respect to the new 10.4 cloud auto registration based upon E 1.6.2 etc etc. My cloud stopped working.
To make a long story short... Would someone point me at a way to execute the preseed debconf scripts such that I can get the non-node controller configuration set up in the new environment or tell me how I can get a reinstall of the packages to asked the questions and do the config. I am stuck as of now.

As reported on Launchpad as bug 574468, installation of 64-bit Ubuntu 10.04 fails on IBM Bladecenters because the installer fails to detect the CD, due to a bug that has yet to be tracked down. I've developed a workaround that will allow Ubuntu 10.04 Server to be installed on a Bladecenter blade by mounting an Ubuntu Server ISO image as a loopback device (and then further working around issues that arise from manually mounting the ISO image), and want to document it here. You will need:
1. an Ubuntu Server 10.04 CD.
2. a USB stick formatted as ext2 with the Ubuntu Server ISO image stored on it. Other file systems may work as well, however fat32 does not seem to work, as I was unable to mount a fat32 USB stick in the installer shell.
3. a Bladecenter with a CD drive and a USB port. Both devices should be "attached" to whichever blade you're trying to install Ubuntu on.
Installation Steps
1. boot your blade to the Ubuntu Server CD. Make sure the USB stick is plugged in as well.
2. proceed with the installer as normal, setting the keyboard layout, etc.
3. when the installer gets to the point where it fails to detect the CD, go back to the main menu and select "Execute Shell."
4. in the shell, mount the USB stick with commands like these:
Code:
mkdir /mnt/sdb1
mount /dev/sdb1 /mnt/sdb1
5. copy the Ubuntu Server ISO image to the /root directory of the live file system with a command like:
Code:
cp /mnt/sdb1/ubuntu-10.04-server-amd64.iso /root/ubuntu-10.04-server-amd64.iso
6. mount the Ubuntu Server ISO image as a loopback device with mountpoint /cdrom:
Code:
mount -o loop -t iso9660 /root/ubuntu-10.04-server-amd64.iso /cdrom
7. unmount the USB stick (but leave it plugged in):
Code:
umount /dev/sdb1
Unmounting the USB stick seemed to be necessary in order to work around the "Failed to determine codename" issue detailed below in steps 9 and 10.
8. type "exit" to exit the shell and go back to the main menu. From there, select the option to detect the CD ROM.
9. continue with the installation. It will go through networking and partitioning. After partitioning, however, it will fail again, complaining that it "Failed to determine codename for release."
10. at this point, go back to the main menu and choose the option to "Load installer components from CD." Then check the option that reads "Load Installer Components from an ISO Image" and press Continue.
After the packages for detecting and loading ISOs are installed, the installer should automatically search all available disk drives (mounted and unmounted) for ISO images.
It should find the ISO image stored on your USB key and mount it.the installation will continue as normal and you will not get the error message about failing to determine the codename for the release. If this process fails, go back to the command shell and unmount your USB key--for some reason I found that if the key was mounted, the installer wasn't able to auto-detect the ISO image stored on it.
The codename issue seems to be related to the installer not liking that the ISO image was mounted manually. Letting the installer find and mount the ISO image itself apparently allows it to perform whatever magic is required to allow the installation to proceed. I figured this out mostly thanks to the tip in post #3 of bug 122402. Here's hoping the real bug gets fixed soon so that all this hassle is not necessary in order to install an LTS release on popular server hardware.

I want to install Ubuntu Server on my server, but I can't move my monitor. What I have tried to do:
1. Install Ubuntu Server onto Computer A.
2. Move Computer A's hard disk into Computer B.
3. Boot Computer B without a monitor.
4. Use SSH to get a remote terminal. This is where my problem is.
Is this possible? I told the installer to install the OpenSSH Server, so it should work, right?

I'm trying to install Alternative PHP Cache on my web server and am running into an error with pecl.
Code:
checking whether apc needs to get compiler flags from apxs...I was not able to successfully run APXS. Possible reasons:
1. Perl is not installed;
2. Apache was not compiled with DSO support (--enable-module=so);
3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs
The output of /var/tmp/pear-build-root/APC-3.0.19/y follows

I have a computer with Windows XP and Xubuntu 10.10 on it. And I would also like to install Ubuntu Server on it, with all OS side by side (Win XP + Xubuntu + Ubuntu Server). Can I do this. Or is the dualboot technologie limited to 2 OS? So I actually want a "triple boot".

I have been following the guide atand it has all worked perfectly and as expected, except for when it says to run "telnet localhost 25". Instead of getting an ip address displayed as I have seen it is supposed to, it just out puts this."Trying 127.0.0.1...Connected to localhost.localdomain.Escape character is '^]'.Connection closed by foreign host."

I am trying to set up my 11.04 ubuntu install so that php can access ms-sql servers. I have done this twice before once with ver 9.10 and centos 5. So I figure I would follow the same steps again as I did last time. but its not working this time around. I get to building php and get the following error. I do not often build packages as I dont know much about it so I figure I have missed something some place. Can anyone tell me what this means and a clue to where I can find the fix.
