Ubuntu Servers :: Adding NIC To Server?
Jan 15, 2010
This probably sounds like a stupid question, but I need to add a NIC to an existing server running Ubuntu Server edition 8.10. My question is what changes I need to make once the NIC is physically installed? I guess it will not be autoconfigured, so I will have to add it to the /etc/network/interfaces manually, which is ok as I need to set it up with a static interface anyway.Is there a good How-to or set of instructions on how to do this?

I installed and configured LDAP server and client on RHEL5 successfully. Problem is that when I add more than one user on server and clients, It shows error 'invalid user'.When I run the command:-#chown -R user:users /home/user, It shows error 'invalid user'. by step for adding and modifying more users in ldap servers.

When i try to join my Ubuntu server to Microsoft Active Directory domain, i get the error message below.
Kinit failed: Clock skew too great Failed to join domain: Time difference at domain controller I know the reason is because of the time difference between my domain controller and the Ubuntu server. But what i want to know is that possible to join a domain without time synchronisation? Because my domain controller is working for another time zone, for another Country, so i can not synchronise it with my Ubuntu server.

I'm trying to switch over my old server(9.10) data to a different server(10.04). My old server only had 2 drive bays, whereas my new one has 4. I already have my new server up and running(for the most part), and want to add the old hard drive to it. How would I do this without losing any information. I believe even my old drive is formatted to ext4. I was going to just throw it in there, but I'm afraid of losing information as I really don't want to lose a 1tb of info. I did try to search, but my title had too many common words in it.

I currently have an Ubuntu Server setup with a CF card that has / and /boot on their own partitions. I also have a single 1TB drive that is dedicated to the /home partition, however it's a drive that I have run out of space on.
I just purchased a 1.5TB drive to throw in the server, but I am not sure how to set this drive up so that it's seamlessly integrated with the 1TB drive. I would like it setup so that my /home partition is expanded from 1Tb to 2.5TB. I know what I am explaining is similar to raid 0, of which I am not opposed to, except that everything I have searched for online solely explains a raid setup during installation, and I don't have the time (due to school) to reinstall and reconfigure my system.
So in a nutshell, is there a way to setup raid 0 without doing a re-install or is there a way to setup 'fstab' to accomadate my request?

I need some help on this one. I added an second internal hard drive to my file server, a 500GB WD. I want to use this drive as the primary storage drive for my file server, and I want to format it with XFS. I've found some guides showing me how to add hard drives, but they didn't really fit what I want to do. When I run fdisk -l this is what I get
Code:
Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0001af4f
[code]....
Disk /dev/sdb doesn't contain a valid partition table

I'm testing a support ticketing system (osTicket), and am trying to set up the server so it can send and receive messages using an external email account so it will, you know, work.When you try to add an email account, it spits out the error "IMAP doesn't exist. PHP must be compiled with IMAP enabled." in the web interface.So apparently IMAP isn't enabled in PHP. And apparently I have to recompile PHP to add that particular function. Um... how i do that? i not so good with computer

I'm setting up a server on Ubuntu 10.04 for development. It all seems to work nicely, I just have one thing that's bugging me. I have a project in /var/www/portfolio, which is as you may guess my portfolio. Instead of the link http://localhost/portfolio I'd like to use http://portfolio.nl. So I set up a file 'portfolio.nl' under sites-available and a symlink on sites-enabled containing this: To get this to work on my local machine I set up this in /etc/hosts:

I want to setup my MySQL database and have MySQL up and running. I sill look for a good editor to add and configure my tables, it appears that MySQL Administrator is the only GUI client available.
But when I try to add a foreign key to one of my tables, there appears to be a problem. Both of my tables are InnoDB and both have a primary key.
-First I choose the tab "Foreign Keys" on my CLIENT table.
-Then I press the green + sign to add a foreign key, it is default named new_fk_constraint.
-I choose my table USER in the Refer.Table dropdownbox
-And then I should be able to match the FK field and the PK field in the box on the right... but this box is empty. Double clicking shows nothing. I only can drag the user_id of the USER table to it, but have no option to select the foreign column.
What the hell is wrong here??? This client is years old and should be really REALLY working IMHO! I was told by a friend that there is no good client available and therefore he is using some Windows program for this...

I have a little nice Ubuntu server with 6x 1TB drives assebmbled into a RAID5 array. Recently SATA cable of one of the drives failed. So I ordered a new cable and ran the server in degraded mode for a few days. Like this:
Code:
/dev/md0:
Version : 00.90
Creation Time : Sat Sep 19 10:39:11 2009
Raid Level : raid5
Array Size : 4883812480 (4657.57 GiB 5001.02 GB)
code....
I'd like the 6th drive to be active, not spare, like before. Should I just wait for rebuild to be finished (it can easily take over 1 day)? Or should I add it somehow differently to be active immediately?
I'm not sure, but I think as I simulated failures unplugging one of the disk, after plugging it in again, the "failed" drive was active again and rebuilding was started as well of course. But it was 2 years ago, so...
The array works just fine for now - I can access files, etc. But I suspect, that in this state if another cable or drive fails, it won't survive anymore. Even after rebuilding is finished, but the 6th drive stays is still marked as "spare". Right?

I have Ubuntu 10.04.2 (Linux 2.6.32-33-server on x86_64) with OpenLDAP 2.4.21 and Webmin1.550. I converted my ldap database from another system with the older style schema (OpenLDAP 2.3.3 with slightly older Webmin version 1.480) and no longer use slapd.conf, but the newer slapd.d format.
It all works fine except for one thing. When I add a new user, it lets me type in the additional LDAP fields:
But when I click the Create button, all the fields get jumbled together in the Title/Position box with a diamond question mark delimiting the fields:
Modifying existing users (which have the Additional fields displaying correctly) also has the same result - it moves the fields all into the one Title/Position box with the diamond shapes with question marks inside between each entry. Is it a problem with my schema files? I tried reverting to the older shema files and slapd.conf and it still did the same thing on the new system. I am really at a loss.
Here is also the output of ldapsearch for that user (host and samba ids are sanitized):
Previously added users that show the fields properly have "description:" and then the field listed for each Additional LDAP field. Also shouldn't the "title" be visible in plain human readable text here? - it looks like it encrypted it somehow - similar to a password hash. The older system works fine and the fields are all readable and in their proper locations. But the new system just doesn't work right.

when changing /etc/network/interfaces and adding incorrect variables. next time you reboot the system it won't start. in the past with 9.10 & 9.04 ubuntu used to ignore these errors in the file and continue booting. allowing us to correct them later. is there anyway to skip these boot errors?

I rented a server to run CS 1.6 game servers. I had someone install Apache and configure my server to be able to use control panel for my game servers( i am running 4 gservers and have 5 ips = 1 ip is free). When i type my primary ip in the web browser it displays the Apache test page.
My question is can i add pages to the Apache without messing up anything with the control panel or my game servers. I am familiar with html. My primary ip is used for 1 of th egame servers but i can change that if necessary. And if possible to add pages how to add a site name, sth like [url] instead of entering the primary ip to display the content.

I have Ubuntu Server 9.10 up and running as my file server. However, it sits amongst other PCs running XP Pro and Network Printers (e.g. Xerox Docuprint C2535A) on the network. My question is whether there is a way of adding the Xerox printer to the Ubuntu Server so that other PCs will send print jobs through the server. I think the printer is windows-based printer. Is it possible to do this? or are there any other options that you may be able to share with me?

Afternoon all, we have an older box which hosts all our corporate mail, but he's a bit old, small hard drive, etc. We have a new app which sends a lot of mail and 2 weekends in a row has killed the box.So I want to play a bit with postfix, and have it installed and ready. The main question is can I have him 'send' all the mail out but keep the incoming since it's not much going to the primary? Naturally it's yes, but what do I need to look at record wise?I know there are new things like spf, spoofing, etc and when someone get's that message from admin@domain.com, there servers naturally reverse lookup, but he won't be the box that receives for that domain so will it simply not accept?

I have configured a CENTOS 5.5 server with DHCP + DNS. The network environment contains clients to obtain IP dynamically and some amy be configured manually. Until noe I have not used any GUIs for the configuration.
Now I want to manually add some hosts to my DNS. Can this be done by directly adding the host names to data files (pointed by the f/w and rev zones)? Or should this be done differently?
What are the good DNS GUI tools available for CentOS?

I'm an experienced PC technician running a slackware 13.1 distro on a server at home. I've currently got 2x 1TB drives in the box allocated as raid1 for the OS and everything I want to run on the machine. I'd like to think my question/needs are fairly straight forward, I am buying 2x 2TB drives to add to this machine as it serves as a NAS box for one of its roles. I'd like these in raid0 as the data that would be going on it is not that important to me. The question is, after adding the new drives to the system, once I boot up, what do I need to do to the system to get the drives added and working sucessfully as a single raid0 volume that I can then samba share out to my network. To clarify, I understand a little of mdadm as I've used it to raid1 my existing setup when I installed, and I'm fine with the samba bit after.

I currently have a home server, running Gentoo, with IPv4 connectivity through Qwest.I feel that it is important that this server also be available through IPv6 (I'm aware that, after exhaustion, my end still might not get an address through DHCP).I currently use dyndns.org to provide me with a DNS entry mapping jrvanwhy.homelinux.net to my IPv4 address.I do not have any sort of tunnel set up yet for IPv6 traffic yet. The new domain name does not necessarily have to be the same [URL].I do not wish to spend any money on this.Is there some free service I can register for that would do both the tunneling and the DNS entry? Is there a service that can supply me with an IPv6 DNS entry, if I get a static IPv6 address with another tunnel broker, like Hurricane Electric?

Code:
The authenticity of host 'myserver.com (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 9b:ee:a6:47:hb:92:ac:76:81:94:18:7d:ad:8c:3e:25.
