Ubuntu Servers :: Software RAID Doesn't Work?
Jul 2, 2011
I'm trying to put two identical disks in Raid 1 for a homeserver. I got Ubuntu 11.04 server 32 bits on a USB stick. Installated till partition menu. Now I get the question how I want to partition my disks. I choose manual, and two times entire disk, one for both. It looks like this:
(iPhone quality)
I go to configure software Raid, and select Raid 1, 2 active disks, 0 spare disks, and get this:
I can't choose the other 2TB partition. I think I have to configure Raid three times, one for each partition. Not?
I click the missing 2TB partition, and get this:
But I think there's no RAID device at all, I see this again when I go to Configure Software Raid, en try to delete a RAID device:
How do I get Disk 1 and Disk 2 together in Raid 1? [URL]

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

I can't connect to my ssh-server (on ubuntu 10.04) from any external address. The error in putty is "connection timed out". From my internal network, everything works fine, even if I select my external IP address and port in putty as the destination.
This is what I have done so far:
installed open ssh with the ubuntu server 10.04 cd
set up port forwarding (11041) in my router (seems to work ok, port is open according to "shields up")
configured ssh to use port 11041 in /etc/ssh/sshd_config
changed tcp and udp ssh port in /etc/services to 11041
enabled UFW and did sudo ufw allow ssh

I'm really new with Ubuntu and have the following problem:I installed successfully sun-java6-jdk using apt-get install sun-java6-jdk Then set up the JAVA_HOME environment variable to "/usr/lib/jvm/java-6-sun-1.6.0.20"
And then installed successfully tomcat6 using apt-get install tomcat6 apt-get install tomcat6-admin tomcat6-examples tomcat6-docs Everything seem to be right, when I try the browser with http://localhost:8080 return a webpage with "It works !" and other text
But, if I try http://localhost:8080/manager/html then returns 404 error, the error is something like "The required resource (manager/html) is not available" (that is my translation from the spanish text "El recurso requerido (/manager/html) no est disponible")

I recently installed vsftpd on my system and it was running fine for my system users. Now I wanted to add virtual users so I googled it, I found this tutorial: [URL]
I did what they've been saying over there but when I restarted the vsftpd I couldn't login with the virtual user and also not with the system user anymore. This is the error ( with the system user who could login before ):
Code:
Status:Verbinden met 109.230.234.21:21...
Status:Verbinding aangemaakt, welkomstbericht afwachten...
Antwoord:220 (vsFTPd 2.2.2)

Last night I was able to set up my server so that I can just connect vnc. I even was able to be connected at the log on screen so I could select which user I wanted to log in at. For some reason today, I have to have the monitor plugged in all the until the logon screen comes up before vnc will connect. Once the logon screen is up, I then can connect via vnc & select which user I want to logon as. It's odd because it worked last nigh, but today - Nope nada, it doesn't work & I can't explain why. I did clean up - Removing some applications I don't need on my server. (I'm hoping that isn't the problem) It's odd as well because I don't have to be logged on as a user to connect via vnc, I just have to wait until the logon screen is available...Then I can unplugged the monitor & logon.

I am developing/testing a PHP app on my netbook. For some reason apache/php are returning nothing but a "500 internal server error" response when there is a problem with my php script. For example, if there is a semicolon or closing brace missing, it should cause the script to die with a hint about which line caused the script to stop working. Instead it displays nothing but a "500 internal server error" message.

I installed apache on my local machine to test my sites. I have one problem:I created a new site configuration in /etc/apache2/sites-available and enabled it. The problem is that cgi is not working, it just prints the content of the files. (The default location for cgi, /usr/lib/cgi-bin works without problem.)Here is the content of the site configuration file:
Code:

I recently moved from Ubuntu Desktop to Ubuntu Server. I have a Dell D600 acting as a three prong firewall. I use a Netgear FA120 USB NIC for the third prong. After converting to Server, the NIC detects as Eth1. I'm able to configure an IP, but the NIC never sends or receives packets. The same NIC works great in Ubuntu Desktop. Dmesg never shows the NIC being ready.

I got ubuntu samba server on server 10.04 username:user1 , Home folder: /home/user1 This user connects from a macbook pro no problem. I followed the same steps to set up user2 username:user2 , Home folder: /home/user2 This user does not connect from windows vista. I have the correct ports open, 137-139 & 445, and can connect from the macintosh, but not vista. The error says that the username or password is in correct. If you need some log files or config files, just let me know where to go and they're all yours!

I have a small problem with lmsensors and snmp since I upgraded my small server from 9.10 to 10.04. I use cacti to monitor my servers usage, disk space as well as temps and fans.
This was running very fine before the upgrade, but now I don't get data anymore from lmsensors. It seems that SNMP doesn't give this information as before. (Cacti log says: "No sensor data was returned from SNMP")
sensors give the following output:
Code:
w83627dhg-isa-0290
Adapter: ISA adapter
Vcore: +1.12 V (min = +0.00 V, max = +1.74 V)
AVCC: +3.41 V (min = +2.98 V, max = +3.63 V)

I'm running a server with Ubuntu 10.04 and I have installed postfix and courier. The server can recieve mail and I can fetch them using POP, but when I try to send mail it doesn't work. Postfix itself can send email if i telnet from localhost and I am using my ISP as a relay because they block port 25. I'm using outlook 2007 on my client computer and it just says that the server rejects the login attempt and tells me to check my username and password. Postfix listens on port 12 as well because the client connection also has outgoing on port 25 blocked. I have tried to use telnet to connect to the server, and I can connect. This is what I get:
[Code]....
Now what? I've tried searching for the answer but all I can come up with is AUTH PLAIN or AUTH LOGIN, but I don't know what to type after that.

I recently installed Fedora 13 on VMware 7 environment without X window. sshd did work fine, but when I tried to put it into xinetd, it doesn't work any more. Here is what I have done so far :
I stopped sshd. #service sshd stop
and I configured xinetd.conf like below.
Quote:
#
# This is the master xinetd configuration file. Settings in the
# default section will be inherited by all service configurations
# unless explicitly overridden in the service configuration. See
# xinetd.conf in the man pages for a more detailed explanation of
# these attributes.
[Code]....
I don't know what I did wrong with them. I configured xinetd.conf, and I made service configuration file 'ssh' in /etc/xinetd.d, and I restarted xinetd.
What am I supposed to do to make a life on my sshd within xinetd ?

I created a new virtual host in Apache using Webmin and am having trouble getting it to work. When I created it, I opted to create the config file as a "New file under virtual servers directory /etc/apache2/sites-available". So now I have a default config file /etc/apache2/sites-available/default and a new one created by Webmin at /etc/apache2/sites-available/webmin.1412323.conf. It seems like the settings in that new Webmin config file aren't being picked up by Apache -- when I try and browse to mywebsite.com it shows my root /var/www folder, not the subdirectory /var/www/mywebsite.
Is there a way I can tell Apache to include the new Webmin config file for the virtual host or should I just copy the directives into the default file at /etc/apache2/sites-available/default? It seems like Webmin should automatically configure Apache to work with any newly generated config files.

I'm at a loss to why my reverse lookup zone doesn't work for me.I've got two views. One internal and one external. My domain is isp2.datornatverk.se. Public IP: 130.240.133.81.
dig -x @8.8.8.8 130.240.133.81
gives me:
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2917
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
I've set it up so that the internal subnets gets the domains resolved to the internal IP-addresses. When querying from external addresses I will get public IP.My named.conf.local file:
Code:
acl internals {
127.0.0.0/8;[code]..........
I don't know whether the views has messed something up. It worked before I added the views.

A week ago or so neither ssh nor scp were working when attempting to connect to my on-campus computer from home. ssh was complainig about the key not matching and I figured out I could just delete the config file it was reading the (now old) key from and let it create a new one with the updated key upon prompting me whether or not to trust the remote host.
However, even though ssh is now working, I can no longer use scp. I issued scp -v and discovered a bunch of errors. scp prompts me for the remote password and even prints the message of the day on the remote computer but then just hangs and doesn't seem to be copying any files. I'm sure the issue is with the whole key change issue but I can't quite figure out why ssh would be working just fine and scp would be failing.

When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:

I'm having trouble getting compiz to work on my Laptop. It worked for a while and then I turned on Shift Switcher and a message popped up saying..."The new value for the button binding for the action Terminate in plugin Shift Switcher conflicts with the action Zoom Window of the Scale Addons plugin. Do you wish to disable Zoom Window in the Scale Addons plugin?" I was given the option of Set Terminate anyway, Don't set Terminate, and Disable Zoom Window. I clicked Don't set Terminate and ever since the only thing that works in compiz are the bindings in the general options. I've used synaptic to completely remove and then reinstall compiz but the problem persist. Something else weird, all of the changes I made are still there, even after complete removal, but they don't work?

I just recently (about an hour ago) installed Ubuntu Netbook edition on my old laptop, and I was greeted with the message, that unity could not be run due to some sort of missing driver...fair enough, I was then greeted with the default Ubuntu desktop, I installed all my needed software (wine, google chrome) and installed the missing display drivers. I then rebooted the system, and once again I am stuck with the default desktop, and not the Unity interface. I checked the software center, and it says Unity IS in fact installed.. And yet I cannot make it appear. So now I ask you Ubuntu veterans. How do I make it work?
P.S. I wiped the system of windows, and the computer is an old HP Pavilion DV6000
