How to setup a static multicast ARP entry with Cisco SG300?

- by Fredrik Hedberg

We're running a Microsoft NLB cluster in multicast mode as a loadbalancer. Using our old Cisco IOS switches we propagate access to the cluster to our branches using a static ARP entry in the core router: arp 10.20.1.226 03bf.0a14.01e2 ARPA But how does one solve this using non-IOS based Cisco hardware such as the SG300 series? Adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.

If i understand right, the following core dump means that the cpu4 has crashed the Host if i read the next line it seem that at the time the CPU 4 was assigned to the NexentaStore Vm ... SO if im right i can say that NexentaStor Vm crash my esxi Am i right ?

Does "Noctua NH-U12-DX 1366" mount on Asus p6t 1366?

- by Andrea Ambu

On Noctua site they state: Caution: The NH-U12DX 1366 can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that don’t have such a backplate. How do I know if Asus p6t has it?

Mounting a share with spaces in FreeBSD fstab

- by Blake

I'm trying to mount a smb network share in fstab on FreeBSD, which works fine for a share without spaces, but fails if a space is in the name. I have replaced the space with \040 which is what everything on google has said, but that didn't help. Share name I'm trying to mount is "Data Backups". Share name as written in fstab that doesn't work: //USERNAME@COMPUTER/Data\040Backups Any suggestions?

Migrate from MySQL to PostgreSQL on Linux (Kubuntu)

- by Dave Jarvis

Storyline Trying to migrate a database from MySQL to PostgreSQL. All the documentation I have read covers, in great detail, how to migrate the structure. I have found very little documentation on migrating the data. The schema has 13 tables (which have been migrated successfully) and 9 GB of data. MySQL version: 5.1.x PostgreSQL version: 8.4.x I want to use the R programming language to analyze the data using SQL select statements; PostgreSQL has PL/R, but MySQL has nothing (as far as I can tell). A long time ago in a galaxy far, far away... Create the database location (/var has insufficient space; also dislike having the PostgreSQL version number everywhere -- upgrading would break scripts!): sudo mkdir -p /home/postgres/main sudo cp -Rp /var/lib/postgresql/8.4/main /home/postgres sudo chown -R postgres.postgres /home/postgres sudo chmod -R 700 /home/postgres sudo usermod -d /home/postgres/ postgres All good to here. Next, restart the server and configure the database using these installation instructions: sudo apt-get install postgresql pgadmin3 sudo /etc/init.d/postgresql-8.4 stop sudo vi /etc/postgresql/8.4/main/postgresql.conf Change data_directory to /home/postgres/main sudo /etc/init.d/postgresql-8.4 start sudo -u postgres psql postgres \password postgres sudo -u postgres createdb climate pgadmin3 Use pgadmin3 to configure the database and create a schema. A New Hope The episode began in a remote shell known as bash, with both databases running, and the installation of a command with a most unusual logo: SQL Fairy. perl Makefile.PL sudo make install sudo apt-get install perl-doc (strangely, it is not called perldoc) perldoc SQL::Translator::Manual Extract a PostgreSQL-friendly DDL and all the MySQL data: sqlt -f DBI --dsn dbi:mysql:climate --db-user user --db-password password -t PostgreSQL > climate-pg-ddl.sql mysqldump --skip-add-locks --complete-insert --no-create-db --no-create-info --quick --result-file="climate-my.sql" --databases climate --skip-comments -u root -p The Database Strikes Back Recreate the structure in PostgreSQL as follows: pgadmin3 (switch to it) Click the Execute arbitrary SQL queries icon Open climate-pg-ddl.sql Search for TABLE " replace with TABLE climate." (insert the schema name climate) Search for on " replace with on climate." (insert the schema name climate) Press F5 to execute This results in: Query returned successfully with no result in 122 ms. Replies of the Jedi At this point I am stumped. Where do I go from here (what are the steps) to convert climate-my.sql to climate-pg.sql so that they can be executed against PostgreSQL? How to I make sure the indexes are copied over correctly (to maintain referential integrity; I don't have constraints at the moment to ease the transition)? How do I ensure that adding new rows in PostgreSQL will start enumerating from the index of the last row inserted (and not conflict with an existing primary key from the sequence)? Resources A fair bit of information was needed to get this far: https://help.ubuntu.com/community/PostgreSQL http://articles.sitepoint.com/article/site-mysql-postgresql-1 http://wiki.postgresql.org/wiki/Converting_from_other_Databases_to_PostgreSQL#MySQL http://pgfoundry.org/frs/shownotes.php?release_id=810 http://sqlfairy.sourceforge.net/ Thank you!

IIS on localhost is very slow

- by Nyla Pareska

I am using IIS7 on Windows Vista dual core cpu. The first time hit on a WCF service or an ASP.NET webform sometimes takes way longer than a minute which is not really acceptable for me. I configured the application to use the Classic .NET application pool and tried playing with the Maximum worker processes, first setting it to 4 but put it back to 1 as it did not have the expected result. Are there any other things that I can try?

I had Windows Vista on my computer and wanted to upgrade to Windows 7 and thought that I would format my computer since it had been awhile. When I installed Windows 7 it wouldnt let me it would go through all the installation and then when my computer rebooted it would just be black screen with my mouse, I have tried mulitpule times now, and have just gone backs to Windows Vista, this no longer works and does the same thing as when I tried to insta I have a Nvidia GTX 275 video card, ASUS m2N-E SLI mother board,and a AMD 5200 Dual core processor

Reality behind wireless security - the weakness of encrypting

- by Cawas

I welcome better key-wording here, both on tags and title, and I'll add more links as soon as possible. For some years I'm trying to conceive a wireless environment that I'd setup anywhere and advise for everyone, including from big enterprises to small home networks of 1 machine. I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even considering hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what walling (building walls) is for the cables. And giving pass-phrases is adding a door with a key. But the cabling without encryption is also insecure. Someone just need to plugin and get your data! And while I can see the use for encrypting data, I don't think it's a security measure in wireless networks. As I said elsewhere, I believe we should encrypt only sensitive data regardless of wires. And passwords should be added to the users, always, not to wifi. For securing files, truly, best solution is backup. Sure all that doesn't happen that often, but I won't consider the most situations where people just don't care. I think there are enough situations where people actually care on using passwords on their OS users, so let's go with that in mind. For being able to break the walls or the door someone will need proper equipment such as a hammer or a master key of some kind. Same is true for breaking the wireless walls in the analogy. But, I'd say true data security is at another place. I keep promoting the Fonera concept as an instance. It opens up a free wifi port, if you choose so, and anyone can connect to the internet through that, without having any access to your LAN. It also uses a QoS which will never let your bandwidth drop from that public usage. That's security, and it's open. And who doesn't want to be able to use internet freely anywhere you can find wifi spots? I have 3G myself, but that's beyond the point here. If I have a wifi at home I want to let people freely use it for internet as to not be an hypocrite and even guests can easily access my files, just for reading access, so I don't need to keep setting up encryption and pass-phrases that are not whole compatible. I'll probably be bashed for promoting the non-usage of WPA 2 with AES or whatever, but I wanted to know from more experienced (super) users out there: what do you think? Is there really a need for encryption to have true wireless security?

reset file permissions?

- by acidzombie24

In my /var/www folder i have permission 2750 with the owner being root (unless i change it by hand) and the group being www-data. I mv a folder into /var/www and i'd like to reset the permissions so everything is 2750 and for the group to be www-data, is it possible to do it in one command? or do i need to do multiple cmds? (its two commands, 3 if i want the same owner but it be nice to do it with one for this folder)

Windows Server 2008 R2 vs Windows 7 Ultimate

- by Techeretic

I have a Dual Core Intel CPU E7200, 4 GB RAM, and a NvIDIA 8600 GT for graphics and 500GB HDD. This configuration runs Windows 7 Ultimate very smoothly, but now I recently signed up to the MS WebSiteSpark programme and have downloaded the Windows Server 2008 R2. So my question is whether I can use the Server Edition for my day to day use, play games, etc etc?? I want to install the Server OS to monitor my Home Network and also for some web development I have been trying out lately.

Bad motherboard / controller / HDs?

- by quidpro

On a leased server, I am running into some timing issues with an application that requires precise timing. Server is a Dual Xeon E5410 running on a Supermicro X7DVL-3 motherboard under CentOs 5.5 x64. The application I am running is timer sensitive and keeps sensing drift whether under load or at idle, but especially under load. I did some investigating with atop and dd and found some mind-blowing numbers. Mind you, I am no Linux guru but something sure seems out of whack. I ran: dd bs=4096 if=/dev/zero of=/bigtestfile to generate disk activity. Regardless whether I wrote it to sda or sdb my DSK value in atop would go over 100%, at one time peaking at 1700%. Again it does not matter if I am writing to sda or sdb.

Problem virtualizing Ubuntu 10.04 32 bit on VirtualBox 3.1 on Windows Vista 64 bit

- by Adam Siddhi

Software & Hardware Setup Host System : Windows Vista Home Premium SP1 64 bit Guest : Ubuntu 10.04 (ubuntu-10.04-desktop-i386.iso) 32 bit VM : VirtualBox 3.1.8 Hardware : Intel Core 2 Duo T6400 4GB SDRAM What Happened I followed the tutorial called Installing Ubuntu inside Windows using VirtualBox located here: www.psychocats.net/ubuntu/virtualbox At first I downloaded ubuntu-10.04-desktop-amd64.iso because I figured that it would be a perfect fit with my Vista 64 OS. I was wrong because it turns out the my Intel Core 2 Duo T6400 CPU does not have Intel® Virtualization Technology. So I had to go with the ubuntu-10.04-desktop-i386.iso which is 32 bit. This got me to the point where I could actually create the Ubuntu VM. So I set up the VM in VirtualBox (according to the tutorial I was following) to prepare for the Ubuntu 10.04 virtualization. Please go to my Picassa web album to see the screen shots of my VM settings and Ubuntu boot process so you can see what I experienced (they appear in the order that I experienced them in). www.picasaweb.google.com/rubysiddhi/ProblemVirtualizingUbuntu100432BitOnVirtualBox31OnWindowsVista64# The first 17 images show the VM settings. The last 8 show my attempt at virtualizing Ubuntu 10.04. You can see booting up but ultimately failing. The Specifics The one error message I got was: (process:210): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) It appeared on a black screen that sort of looked like a Windows console screen but with out the c:\ or the ability to type. Then this error message got more complex when tons of text appeared in the screen. Pictures 23 - 25 in the album show this text. I should also mention that I found this post in the Ubuntu forums by zonination who seemed to have similar problems to mine even though they had a different set up. The main issue I think zonination and me may be having is the fact that we can not change the color mode to 32 bit while it is booting. I think the 16 bit color mode maybe making Ubuntu fail. Not certain though. Well I hope I explained my problem thoroughly and clearly. Thanks for the tutorial. It got me started but, now I hope to finish this process so I can start developing in Ubuntu. OH by the way if you want to actually see what happened play by play (with some classical in the background) check out the video I made over here: http://www.youtube.com/watch?v=XMbbm5E_0Xw Thanks!

Laptop Hard Drive Cable

- by Josh Pennington

I am about to have to dig into my wifes laptop to pull the hard drive out to pull the data off since the rest of it is close to dieing. I am curious what I should expect to have to deal with to get data off the hard drive. I am assuming its a SATA drive. Do I need a special cable to connect a laptop SATA hard drive to the computer or should I be able to connect it to my desktop computer without issue? Thanks Josh Pennington

What is the § ± key for on Mac keyboards?

- by Pat Wallace

Apple's keyboards have a new key, with § and ± symbols on it. Can somebody tell me what these keys are for, and where I should use them? I am aware the symbols have mathematical uses, but I assume they must do something important as well to be on the core keyboard. Or are they just the 'Scroll Lock' of the Apple world?

MariaDB doesn't upgrade, 2 versions are installed

- by zahorak

I have a server running on Debian wheezy with MaraiDB and OwnCloud. Few days ago, I wanted to update the packages because of the OwnCloud updates but something went wrong. Usually in this case I'd probably try to remove and again install the problematic packages, but on a server which is used by different people it doesn't seem like a valid solution anymore. Here you can see my console output: user@server:~$ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these.

Database Mirroring of SQL server

- by jbp117

I have two databases that are mirrored to another server using database mirroring. The mirror server has to be down for some reason for few days. Now the production server is having principal databases in (PRINCIPAL/DISCONNECTED) State. Clients can access those databases. So what happens when they keep on adding data to these databases?? Will the data get committed or waits till the mirror comes up?
