• Configuring three monitors with two Radeon X1600/X1650 graphics cards under Ubuntu

  - by cpm

  I have three SyncMaster 932a monitors I want to use with two Radeon X1600/X1650 cards under Linux. I am running X.org X Server 1.6.0, as provided by Ubuntu's Wubi installer. After turning off mirroring, I ended up with this xorg.conf: Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 2560 1024 EndSubSection EndSection Section "Device" Identifier "Configured Video Device" EndSection The left monitor had a menu bar and a task bar, the center monitor was just desktop, and windows would maximize to the current monitor. The third monitor and second graphics card weren't being used at all. Then I changed my configuration to manually specify each card with their PCI bus: Section "ServerLayout" Identifier "TheLayout" Screen 0 "Radeon Screen 1" Screen 1 "Radeon Screen 2" RightOf "Radeon Screen 1" EndSection Section "Screen" Identifier "Radeon Screen 1" Monitor "Configured Monitor" Device "Radeon the First" SubSection "Display" Virtual 2560 1024 EndSubSection EndSection Section "Screen" Identifier "Radeon Screen 2" Monitor "Configured Monitor" Device "Radeon the Second" EndSection Section "Device" Identifier "Radeon the First" Driver "radeon" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "Radeon the Second" Driver "radeon" BusID "PCI:2:0:0" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Now both the left and right monitors have task bars and menu bars. Windows cannot be dragged from the first two monitors to the third monitor. Also, maximizing in the left or center window fills both monitors. I also tried adding Option "Xinerama" "true" to the ServerLayout section. X11 wasn't able to start up. I want to: Allow moving windows along all three monitors. Maximizing only fills the current monitor. Either have menu/task bars on only the left monitor or all three monitors How can I make this possible?

• Mac computers unable to connect to samba

  - by tan-ce

  I have a Ubuntu 9 server with samba 3.3 installed. This server has two network interfaces, one to a "public network" which I do not have any control over and another to a private LAN. On the private LAN, samba is the Domain Controller and nmbd is the WINS server on that network. On the "public network", I have configured a second instance of nmbd to run as a WINS client. The setup seems to work fine for Windows XP (on the domain or otherwise) as well as other Ubuntu machines. Finally, my question: Mac computers seem unable to connect to the samba server. As far as I can tell, it is as if samba is invisible to the MAC computer. Could my configuration of nmbd be causing this problem? Or is this simple a Mac oddity and is there anything I can do about it? New updates/info: We tried to connect through the Finder - Connect to Server, we entered smb://servername where servername is the netbios and DNS name. (There is also a DNS entry for the same name on the network) We also tried connecting by IP address Also, I just realized that there is at least one Mac which can connect. (Leopard 10.5.8) I will try to get the Mac OS versions of the computers which couldn't connect as soon as I can. The Mac which could not connect was running Mac OS X 10.4.11. Was there a change to samba on Mac OS between 10.4 and 10.5?

• Debian: What are these files in /sys/devices/pci0000:00/ for?

• How can I recover XFS partitions from a formatted HD?

  - by giuprivite

  I deleted the partition table of my HD. I wanted to format another one, but by mistake, I formatted the wrong one. Then I also created some new partition on it. Now I would like, if possible, to recover my old data. The old configuration was this: A primary NTFS partition with Windows, and a secondary partition with four logical partitions: a swap and three XFS partitions (two for Ubuntu and OpenSuSE, and one with the home for both systems). This is the output I get when I run gpart in a terminal: ubuntu@ubuntu:~$ sudo gpart /dev/sdb Begin scan... Possible partition(Windows NT/W2K FS), size(39997mb), offset(0mb) Possible extended partition at offset(39997mb) Possible partition(Linux swap), size(8189mb), offset(39997mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(48187mb) Possible partition(SGI XFS filesystem), size(40942mb), offset(89149mb) Possible partition(SGI XFS filesystem), size(175044mb), offset(130112mb) End scan. Checking partitions...

I have a free second HD of about 500 GB (the formatted one is 320 GB) that I can use for the recovery process.

• Apache taking up a lot of CPU while running request-tracker4

  - by bhowmik

  I am trying out a request-tracker installation on an EC2 micro instance. The specs for the micro instance are as follows 1) Ubuntu 12.04 64bit, 613MB RAM, 8GB Hard Drive 2) Running request-tracker 4.0.4 from the repository, perl 5.14.2, Apache2, MySQL5 3) Request-tracker4.0.4 running with mod_perl2 and Worker mpm 4) Apache configured with Worker MPM. Config snippet given below Timeout 150 KeepAlive On MaxKeepAliveRequests 60 KeepAliveTimeout 2 <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> Now when I start Apache2 it works fine for some time and after a while the CPU load shoots up to 99% or more. Usually it is one or more Apache processes doing this. I've tried a to modify the worker module configuration without any luck. The log files for both Apache2 and request-tracker4 are set to log debug messages and don't show anything to indicate what could be causing this. The system gets a maximum of 5 users at any given time and usually (90% of the time) it is just 2. I've just installed it and we only have 20 tickets in the database. I don't think its the memory thats causing the issue since the server isn't swapping or even close to it and I hardly see the memory usage go up. Would appreciate any pointers on how to go about troubleshooting this. In case it helps I've also tried this out a similar installation on a small instance (Identical settings except RAM bumped upto 1.7GB) and I still see the issue.

• Adding third disk as a single disk in a server with an existing RAID1

  - by slowhandsolo

  I've got a ProLiant DL360 G5 server (Fedora 13) with two SAS disks in a hardware RAID 1, working fine. Now I hot plugged another SAS disk. I'd like to configure this new hard disk out of my RAID, as a single non-RAID disk (ex. /dev/sdb). Even after rebooting the server, I can't see the new disk with "fdisk -l". It displays only my hardware RAID, but not the new disk. [root@myserver]# fdisk -l Disco /dev/cciss/c0d0: 300.0 GB, 299966445568 bytes Disposit.

If relevant, I want to create a new partition in my new disk, format it with mkfs and mount it, but as I can't see it with fdisk, I don't know how to do it. Thanks!

• Compiling PHP with GD and libjpeg support

  - by Robin Winslow

  I compile my own PHP, partly to learn more about how PHP is put together, and partly because I'm always finding I need modules that aren't available by default, and this way I have control over that. My problem is that I can't get JPEG support in PHP. Using CentOS 5.6. Here are my configuration options when compiling PHP 5.3.8: './configure' '--enable-fpm' '--enable-mbstring' '--with-mysql' '--with-mysqli' '--with-gd' '--with-curl' '--with-mcrypt' '--with-zlib' '--with-pear' '--with-gmp' '--with-xsl' '--enable-zip' '--disable-fileinfo' '--with-jpeg-dir=/usr/lib/' The ./configure output says: checking for GD support... yes checking for the location of libjpeg... no checking for the location of libpng... no checking for the location of libXpm... no And then we can see that GD is installed, but that JPEG support isn't there: # php -r 'print_r(gd_info());' Array ( [GD Version] => bundled (2.0.34 compatible) [FreeType Support] => [T1Lib Support] => [GIF Read Support] => 1 [GIF Create Support] => 1 [JPEG Support] => [PNG Support] => 1 [WBMP Support] => 1 [XPM Support] => [XBM Support] => 1 [JIS-mapped Japanese Font Support] => ) I know that PHP needs to be able to find libjpeg, and it obviously can't find a version it's happy with. I would have thought /usr/lib/libjpeg.so or /usr/lib/libjpeg.so.62 would be what it needs, but I supplied it with the correct lib directory (--with-jpeg-dir=/usr/lib/) and it doesn't pick them up so I guess they can't be the right versions. rpm says libjpeg is installed. Should I yum remove and reinstall it, and all it's dependent packages? Might that fix the problem? Here's a paste bin with a collection of hopefully useful system information: http://pastebin.com/ied0kPR6

• "Delivered-To" Header in Exchange

  - by Kaii

  In some SMTP server implementations (i.e. Postfix) you can enable Delivered-To and X-Original-To headers that will be added to your email. (or [X-]Envelope-To) This is very helpful with distribution lists to determine which e-mail address the mail has been redirected to. So, when the mail has been sent to [email protected], you can see in the Delivered-To or Envelope-To header that it has been redirected (distributed) to [email protected], which is one of many other e-mail addresses that are linked to a single mailbox. How do I find which address was used to deliver this mail to a specific mailbox on Microsoft Exchange 2010? Looking at the plain message (with all headers) i can not find any information that the mail arrived via address [email protected] I think I need the Delivered-To header (or a similar one) to be set on Microsoft Exchange when a mail is delivered via distribution lists. Is there any way to enable such header in Exchange 2010? I need it so that our Ticket system (OTRS) correctly recognizes where the ticket belongs to. Adding all the e-mail addresses of all distribution lists to the system configuration is not the right solution. And if there is a solution for Exchange 2010, is this possibly also applicable to Exchange 2007?

• How to set up port forwarding on a dedicated server running CentOS 5.4 to use Ubuntu 9.0.4

  - by mairtinh

  The basic situation that I have is a dedicated server running CentOS 5.4 At the moment I have one VM running Ubuntu 9.0.4. Later on, I will want to add another VM running Windows Server 2003 but at the moment I am focusing on getting Ubuntu up and running. The Ubuntu installation is working fine but I'm seriously struggling to get port forwarding working so that I can access websites to be hosted on the Ubuntu VM. As a newbie to Linux, I am confused about the relationship between IPTables and VMWare's own port forwarding. Here's what I've tried so far. The IP of my server is xxx.xxx.xxx.xxx and the provider support have told me that the subnet mask is 255.255.255.0, the gateway address is xxx.xxx.xxx.1 and the network address is xxx.xxx.xxx.0. (Those latter two surprise me a bit, I expected private gateway/network address rather than public ones.) First of all I tried Bridged Networking but had no success at all in communicating with the machine other than through the VMware console. I tried pinging it from the host (using ssh into the host) but no joy; also no Inernet access from the VM. I changed the interfaces configuration from DHCP to Static, using a static address of 192.168.1.100 and setting the gateway to xxx.xxx.xxx.1 as advised by the provider. No real difference, still cannot ping the guest from the host or vice versa and no Internet access from the guest. Then I tried NAT. The host automatically set the IP address to 192.168.132.128 with a gateway of 192.168.132.2 Now the guest has Internet access out and when I do a VNC to the host and open Firefox with 192.168.132.128 I can see the hosted website okay but I still cannot get into it from outside. I mentioned that I'm a bit confused about IPtables and VMware port forwarding, what I meant is that I'm not sure whether IPtable forwarding should be set to the IP address of the guest interface (192.168.132.128 in this case) or the gateway address 192.168.132.2 . I have a feeling that I'm missing something very simple here, can anybody tell me what it is?

• JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

  - by mfarver

  I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

• Terrible noises from subwoofer of ACER Aspire 6930 with Realtek sound chip

  - by OneWorld

  After approximately 5-15 min of listening to music my subwoofer begins to make terrible noises. He's just "coughing". That began after 6 months I had this computer. Now I found out, that I can temporarily fix this problem by "restarting" the audio stream of the application that plays music. For example reloading last.fm page (reloads the flash file). Another way to reset the audio playback is switching the speaker configuration shown below in the screenshot. According to many posts on the internet like http://www.tomshardware.co.uk/forum/52918-20-acer-aspire-6935g-speaker-problem ACER support isn't any help Exchanging hardware doesn't fix the problem Even the later models have this problem Turning off the volume of the subwoofer is not an option to me. I still have warranty (I bought an extension of one year). I already tried about 15 versions of the Realtek driver with no success. I am not sure but MAYBE the problem did not occur on the original windows vista that was shipped with this computer. However, I removed the original windows for good reasons (english). What do you suggest me? Did anyone fix this problem? Maybe by writing a script which resets the audio streams every 5 minutes? Shall I take the effort to deal with the acer support until they give me another model? (I won't have a computer than for a longer time, will spend money on telephone hotlines (1,30 EUR / min)......) Here are additional infos, if they are any help: Windows 7 64 Bit (Original was Windows Vista Home Premium 32 Bit) All specs Audio driver version:

• mysql INNODB inserts very slow

  - by 133794m3r

  The database's schema is as follows. CREATE TABLE `items` ( `id` mediumint( 8 ) unsigned NOT NULL AUTO_INCREMENT , `name` varchar( 45 ) NOT NULL , `main_type` tinyint( 4 ) NOT NULL , `rarity` tinyint( 4 ) NOT NULL , `stack_size` smallint( 6 ) NOT NULL , `sub_type` tinyint( 4 ) NOT NULL , `cost` mediumint( 8 ) unsigned NOT NULL , `ilvl` smallint( 6 ) unsigned NOT NULL DEFAULT '0', `flavor_text` varchar( 250 ) NOT NULL , `rlvl` tinyint( 3 ) unsigned NOT NULL , `final` tinyint( 4 ) NOT NULL DEFAULT '0', PRIMARY KEY ( `id` ) ) ENGINE = InnoDB DEFAULT CHARSET = ascii; Now, doing an insert on this table takes 0.22 seconds. I don't know why it's taking so long to do a single row insert. Reads are really really fast something like 0.005 seconds. With using the example configuration from here dev mysql innodb it averages ~0.002 to ~0.005 seconds. Why it takes more than 100x more time to do a single insert makes no sense to me. My computer is as follows. OS:Debian Sid x86-x64, Mysql 5.1, RAM:4GB ddr2, cpu 2.0Ghz dual core, HDD 7200RPM 32MB cache 640GB. Why it's taking almost 100x as much time for a SELECT * FROM items; vs INSERT INTO items ...; will never make any sense to me. It's still a small table at only 70 rows, and took that long even when it had 0 rows.

• Hiera datatypes wont load in Puppet

  I am trying to get mongrel cluster working on my Ubuntu Server Karmic box in preparation to setup Capistrano. I've been trying to get the two to work all day and finally decided to completely remove Capistrano and see if I can just get Mongrel Cluster to work. I ran this to install mongrel cluster: gem install mongrel mongrel_cluster Everything installed fine, when I change into my app's directory... # mongrel_rails -bash: mongrel_rails: command not found I can run it from its install location: # /var/lib/gems/1.8/bin/mongrel_rails Usage: mongrel_rails <command> [options] Available commands are: ... It lets me build the cluster configuration file fine, but when I run the clister:start command: # /var/lib/gems/1.8/bin/mongrel_rails cluster::start starting port 8000 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8000 -P tmp/pids/mongrel.8000.pid -l log/mongrel.8000.log starting port 8001 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8001 -P tmp/pids/mongrel.8001.pid -l log/mongrel.8001.log starting port 8002 /usr/lib/ruby/1.8/rubygems/custom_require.rb:31: command not found: mongrel_rails start -d -e production -p 8002 -P tmp/pids/mongrel.8002.pid -l log/mongrel.8002.log It seems it isnt calling it from the right directory after that command, what can I do to fix this? I tried setting the path previously when trying to set up Capistrano, but the path didnt stay set when Capistrano used ssh to run the commands.

• No sound through headset - only mic is working

  - by Kristis

  I noticed that no sound is being played to my headphones. The laptop has a conexant sound card together with the sounds apps provided. But the thing is that I also noticed that now instead of one playback device - 2 are presented: speakers and headphones. And while speakers do play sound nicely - even test sound are not played through headphone output. Also, headphone output does not have a jack assigned to it, while speakers have L R Rear panel Analog Jack(my laptop does not have a jack on the back - only on the right). Also - my headphones have a mic as well - and when I plug it in - the mic is working(using top panel digital jack),but the headphones themselves are not. And laptop is recognizing when audio device is plugged in. And I checked the headset on other devices - the headphones are working. I have tried updating drivers, rolling back drivers and completely uninstalling drivers and then restarting - nothing helped. I imagine that I somehow need to reconfigure the jack configuration just have no idea how and where. Any suggestions? Thanks

• Force Juniper-network client to use split routing

  - by craibuc

  I'm using the Juniper client for OSX ('Network Connect') to access a client's VPN. It appears that the client is configured to not use split-routing. The client's VPN host is not willing to enable split-routing. Is there a way for me to over-ride this configuration or do sometime on my workstation to get the non-client network traffic to by-pass the VPN? This wouldn't be a big deal, but none of my streaming radio stations (e.g. XM) work will connected to their VPN. Apologies for any inaccuracies in the terminology. ** edit ** The Juniper client changes my system's resolve.conf file from: nameserver 192.168.0.1 to: search XXX.com [redacted] nameserver 10.30.16.140 nameserver 10.30.8.140 I've attempted to restore my preferred DNS entry to the file $ sudo echo "nameserver 192.168.0.1" >> /etc/resolv.conf but this results in the following error: -bash: /etc/resolv.conf: Permission denied How does the super-user account not have access to this file? Is there a way to prevent the Juniper client from making changes to this file?

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by indyvoyage

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• MD RAID 1 with external bitmap doesn't fully resync

  - by user64744

  I have an interesting configuration: dual boot system with a RAID 1 that needs to be visible in both Windows and Linux. The Windows install is Win 7 Enterprise, and the Linux install is Kubuntu 10.04. To get the RAID to work, I set it up using Windows's "Dynamic Disks" RAID 1, and brought it up in Linux using MD with no persistent superblock, and a write-intent bitmap on another partition. (Without this bitmap, MD had no way of knowing that the array was in sync, and would do a complete resync every time the array started.) The array is assembled like so: mdadm --build /dev/md1 -l 1 -n 2 -b /var/local/md1.bitmap /dev/sdb2 /dev/sdc2 I expected that the first time I ran this command, it would resync the array, write out a bitmap with no dirty chunks, and all would be good. This wasn't the case: after completing the resync, the bitmap was mostly clean, but about 5% dirty blocks remained, as revealed by mdadm -X /var/local/md1.bitmap I didn't mount the filesystem on /dev/md1 or touch it in any other way. I then found that stopping and restarting the array: mdadm --stop /dev/md1 mdadm --build /dev/md1 -l 1 -n 2 -b /var/local/md1.bitmap /dev/sdb2 /dev/sdc2 did indeed read in the bitmap, with an ensuing resync that went quickly because most of the blocks were marked clean. The confusing part is that this resync further reduced the number of dirty blocks, but still did not remove all of them. By repeatedly stopping and restarting I could slowly bring the dirty block count down to around 0.6%, where it seemed to level out. Any ideas what could be causing this? It smells to me of a race condition somewhere that leads to blocks either being skipped over during synchronization or not properly cleared from the bitmap, but I really have no evidence to prove this. It doesn't look like hardware issues since both drives are new and have zero read errors and reallocated sectors reported by smartctl -a.

• Router startup problems

  - by gfmoz

  I have problems with my Tilgin Vood Router. As I try to start my router by turning the power on (captain obvious), it generally doesn't work the first 3-4 times. This is getting very annoying. Five minutes after turning the power on the router's signal LEDs don't blink in the way they should do in a connected state. I can connect to my routers web configuration interface through my PC connected to it via LAN though I can't access the internet. It usually takes the router five minutes to get to the point where it should be connected to the internet but as it doesn't work the first times. So I turn on my router 3-5 times, let him work 5 minutes and then suddenly, after turning the power off and on again it all works. I also have to restart my PC too in order for everything to work. How can I solve this problem? Just leave the router turned on all time? I prefer a daily IP switch, though. May the problem have something to do with my PC? There is another one connected to the router too and it doesn't work there either.

• Netbook (Samsung N220) on Ubuntu 10.04 slows down WiFi for other computers

  - by Joachim

  I encountered a really odd problem with my new netbook. I am running Ubuntu 10.04 on a Samsung N220 Mito. So far everything worked fine. Now I tried the machine for the first time in our work group where we have a wifi (with internet access) for all laptops. The wifi is controlled by a computer running Suse 9.3 which provides a DHCP server and imposes a firewall. At the moment there is only a macbook in the wifi, where no problems with the internet or wifi connection are encountered. Now coming to my actual problem: In addition to the macbook i connect the Samsung N220 to the Wifi. Problem: My download speed is for some reason limited to 70KB/s max. This is neither a limitation of the server/website i browse on, nor a configuration of the netbook: at home i have 500KB/s download speeds. Furthermore, it is not a default limitation for "untrusted" or "new machines" in the wifi, as for instance other new laptops get full speed internet with our wifi. Problem: Once the Samsung N220 is generating traffic in the wifi, the wifi is slowed down dramatically for all other machines: I run a ping to the router from the macbook. The ping times with the N220 ideling are 2-6ms. When I start downloading or browsing in the web with the N220 the ping speed drops to 800ms. Vice versa, when the macbook is generating the traffic the ping of the N220 to the rooter stays constant at around 2-6ms. So clearly, it is some problem originating from my netbook or maybe its treatment in the wifi. Thanks for any help

• Installing and running a guest OS on KVM-qemu with only serial console access

  - by nixnotwin

  I am trying to installing a bsd distro with virt-installer. With a Linux distro I used this: virt-install -n debian -r 1024 --vcpus=1 --accelerate -v --disk /var/kvm/installation-disks/debian.img,size=6--nographics --network=bridge:br0,model=ne2k_pci,mac=52:54:00:66:68:09 -l http://ftp.de.debian.org/debian/dists/squeeze/main/installer-amd64/current/images/ -x console=ttyS0,115200 This loads the installer directly from the online mirror. With Fedora I used this mirror: http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/releases/16/Fedora/x86_64/os/ Are there such mirrors for freebsd or openbsd? The reason I want direct installable ftp/http mirrors is because I can access my physical server only via ssh, and it doesn't have a X server or a window manager to give me a VNC GUI. When I tried installing centos 6 with an online mirror I was able to finish the installation via serial console, but after I rebooted it, the serial console never worked for me. I tried everything possible---editing menu.lst, inttab and securtty files. Fedora 16 booted fine from serial console, but got stuck when it loaded anaconda installer. I tried editing freebsd iso installation media by adding serial console option to boot option. And installation was successful. But couldn't boot into it becuase it wasn't giving console acess. I couldn't edit any files as ufs partition cannot be loaded with write access on my Ubuntu server 10.04. Only debian squeeze worked well, it worked for me even without editing a single configuration file. I want to have CLI versions of fedora/centos and freebsd/openbsd. But, looks like there isn't any hope for me to have them, as I have to depend on a serial console to do everything.
