• master-slave-slave replication: master will become bottleneck for writes

  - by JMW

  hi, the mysql database has arround 2TB of data. i have a master-slave-slave replication running. the application that uses the database does read (SELECT) queries just on one of the 2 slaves and write (DELETE/INSERT/UPDATE) queries on the master. the application does way more reads, than writes. if we have a problem with the read (SELECT) queries, we can just add another slave database and tell the application, that there is another salve. so it scales well... Currently, the master is running arround 40% disk io due to the writes. So i'm thinking about how to scale the the database in the future. Because one day the master will be overloaded. What could be a solution there? maybe mysql cluster? if so, are there any pitfalls or limitations in switching the database to ndb? thanks a lot in advance... :)

• Will Software RAID And iSCSI Work For A SAN

  - by Justin

  I am looking for a SAN solution, but can't afford even entry level solutions. Basically, the SAN is for development and a proof of concept product. The performance doesn't have to be amazing, but needs to be functional. My buddy says we should just setup sotware RAID and software iSCSI in Linux. Essentially I have a spare server with dual Xeon processors, 4GB of memory, and (2) 500GB 7200RPM drives. It's a bit old but working. I am sure there is reason people don't do software RAID and iSCSI, but will performance be usable? Thinking of configuring the drives in RAID 0 (for performance).

• Motherboard max memory supported

  - by Ashfame

  I have an Intel DG965RY motherboard and its specification says it supports 8GB with 533 or 667Mhz RAM sticks and only 4GB with 800Mhz RAM sticks. I am running a 64bit OS. I earlier had 2 X 1GB sticks (800Mhz), so I bought 2 X 2GB sticks (800Mhz) and I underclocked them in the settings to run at 667Mhz. Shouldn't it support all 6GB RAM now? It would be a bummer if I will specifically need 667Mhz sticks thinking that at the worst they will underclock and then run at 667Mhz. I tried this because I saw someone posted at some forum that he put in 4GB+ of RAM in the same board @ 800Mhz and the system uses it all. In my case (On Ubuntu), it only shows 3.2GB as of now (link to Question) so needed to confirm if this is a hardware limitation.

• What would cause previously sent emails to be sent again from Exchange the first time someone logs i

  - by Ken Pespisa

  A few users testing our Citrix XenApp service found that several (seemingly random) previously sent emails were sent out immediately after they logged into Outlook via Citrix for the first time. The problem hasn't occurred for them since. After one user had this happen, and we scratched our heads about it thinking it was a fluke, our IT director had this same issue. I guess I'd rule out any PEBKAC issues. I really don't know where to begin troubleshooting this problem. If you have any ideas what could have caused this, I'd appreciate you sharing them, as strange or far-fetched as they may seem :)

• making cookies persistent in IE8

  - by Jamie Stevens

  There's a website I sign into frequently, and I'm getting sick of entering my username and password every time. The website can remember who I am so long as I don't close my browser (Internet Explorer 8), but when I do it forgets me, and asks me to login again. I'm guessing this is because it's using a cookie (and perhaps a session) that expires when I close my browser. Is there anyway to make this information persistent across each time I load my browser? (I tried exporting the cookies to a file, and then importing them as soon as the browser was reloaded, but that didn't work either... I'm thinking the cookie text file needs to be modified somehow.) (FYI The website is http://blackboard.unh.edu, but you won't have access unless you happen to be a student there :-) NOTE: I'm not interested in using any password remembering features in the browser. The only solution I'm open to is making the cookie / session persistent somehow!

• Is it possible to tunnel ICMP over TCP?

  - by Robert Atkins

  I don't want to tunnel TCP over ICMP (as ptunnel does), I want to go the other way around. I'm in the situation where I have TCP (HTTP) connectivity to a machine but an internal firewall over which I have no control is swallowing pings. The monitoring software I'm using appears to determine connectivity by attempting to send a ping before it tries to just connect to the web service on the target machine. It's failing this ping test and giving up. I believe if I could fool my monitoring software into thinking pings were getting through, it would then connect to the web service and be on its merry way. Anyone know how I can do this? I have SSH and root access on the destination machine.

• What is a good tool to scan a FTP directory and show disk usage visually ala KDirStat/WinDirStat?

  - by Wesley 'Nonapeptide'

  Is there a tool that can scan an FTP directory and build a visual representation of disk usage? I'm running on Windows so that platform is my preference for this tool, but a *NIX tool would also be useful. I'm thinking along the lines of WinDirStat, KDirStat and TreeSize. At first I thought WinDirStat might be able to scan an FTP directory, but it was not so. FOSS is a plus, but not a requirement (I'm not against paying for good software). I'd like to also have a simple report on how many of what types of files are present, largest files, etc. Much like the simple file type reporting in *DirStat.

• How to use an USB digitizer?

  - by Magnetic_dud

  Hello, i am in China now, and when i saw an USB digitizer (resistive), i bought it, thinking that i could be used as a mouse. When i connect it to my windows 7 rc1 laptop, the system properties says "pen input available" But, nothing happens when i touch the panel... i installed the bundled drivers, in chinese only, and NOT in unicode (so the text is garbled) When i install the driver, i get access to a special key on the tablet, "switch from pen input to mouse", and the driver will move the pointer according to the position on the tablet. (but no click) If i use the "pen mode", the computer will use a special chinese IME that is very awkard, i want to use the microsoft ime, and be able to draw/take notes on the screen There are "generic" drivers? Or just a plain mouse driver that will click when i press on the surface The tablet name is "qiancai"

• Is it possible to restrict fileserver access to domain users using computers that are members of the domain?

  - by Chris Madden

  It seems domain isolation can be used to accomplish, but I'd like a solution that doesn't require IPsec, or more accurately, doesn't require IPsec on the fileserver. IPsec if done in software has a large CPU overhead and our NAS boxes don't support any kind of offload. The goal is to avoid authenticated users using non-managed machines to access network resources. Network Access Protection (NAP) and the various enforcement points looked promsiing but I couldn't find a bulletproof way to use them [which doesn't require IPsec on the fileserver]. I was thinking when a domain user accesses the NAS box it will first need a Kerberos ticket from AD, so if AD could somehow verify the computer that was requesting the ticket was in the domain I'd have a solution.

• Recommendation for PCI SATA addon card?

  - by edmicman

  I have a couple of dead PCs from my wife's office that have working SATA HDDs. Sorry, I don't know if they're SATA I or II, just that they're SATA. Unfortunately, all my spare hardware at home is pretty old; all I have is IDE support. I was thinking I could get a PCI addon card on the cheap that would support SATA and put together a budget server of sorts to play with and be able to use those drives. So I've got a couple questions: After some searching it looks like I can get an addon card for ~20 bucks, but it looks like they're all SATA I? Would that matter? It looks like going to SATAII bumps the price up to $40-$60 or so. Are there any recommendations on a card to get?

• Laptop VGA Out Stopped Working

  - by Jack7890

  I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

• Varnish and plesk

  - by Raphaël

  I have an e-commerce site with 300,000 products and 20,000 categories. It is slow and currently in production. I decided to install Varnish to speed up. The trouble is that during installation, I got a Guru Meditation. Since the site is in production, I am not allowed to leave this error more than a second, thinking to have made an enormous stupidity. I followed the following tutorial: http://www.euperia.com/linux/setting-up-varnish-with-apache-tutorial I'm sure I followed all without error. I say that there may be a specific configuration with plesk. Has anyone already installed Varnish on a ubuntu 10.04 server with plesk 10? Does anyone have a better resource? I know it is "very vague" as an error, but maybe some of you have had this problem. Sincerely,

• How to maximise performance in computers connected into LAN via Gigabit ethernet router?

  - by penyuan

  Our group is setting up a server (which might just be a NAS, but we're not sure yet), which shares files, so that it connects to all other computers in the room (about 10 of them). I am thinking just hooking all of them up via a gigabit router/switch. Is there anything I should watch out for, in terms of cables, connections, or the connection capabilities of each computer in the network? For instance, I don't want a slow computer in the LAN to slow down everyone else's connection, etc., etc. Thanks for the education.

• what are security implications of running Ubuntu inside Windows 7?

  - by EndangeringSpecies

  I am thinking of switching to Ubuntu as a way of making web browsing more secure. So, suppose I will go the easy route and run Ubuntu as an app inside Windows and then run Firefox inside of that. What will this do to the security given the current threat environment? E.g. do most online threats nowadays target the browser and flash (which presumably would be safely sandboxed inside easy to wipe Ubuntu environment) or do they target the Windows TCP-IP stack where Ubuntu would give no protection? Well, most likely the above question does not come near to covering all the security implications of this setup :-), so please do discuss whatever other issues that may be relevant here.

• IRC "proxy" for persistent connection between several computers

  - by Zeta Two

  I'm looking for a program that enables me to stay connected to one or more IRC networks and be able to view the log even though I connect from several different computers. I'm thinking about something like a proxy running on a server who always is connected to the servers/channels I want and to which I connect from whichever client I want to use. Does anyone know of a program like this? Edit: Apparently I could be running a IRC session in a shell on a server and connect to this but I would like something more GUI:ish.

• How to rename everything matching a certain string in a folder

  - by lostiniceland

  Hello Everyone I am running Linux and I have some basic console knowledge but my current problem is quite difficult and I dont know how to achieve this. I want/need to rename everything within a folder that matches a given string. By everything I mean folders/files content within a file content in hidden files Basically I want to refactor a Java-project. Sure, I could use Eclipse to handle the replacing, but this leaves out the folders or resources outside of my workspace. I was thinking of a script that could do the job for me but this seems rather tricky. For instance when it comes to folder-/file-rename I want to replace only the part of the name that matches my string, the rest should remain untouched. Maybe someone already has something like this in his/her script-collection :-) Thanks in advance Marc

• What happens when you add a Graphics card to a i7 with build in graphics (e.g. HD 4000)

  - by Matt

  I'm thinking of upgrading my computer from an AMD Phenom II X4 955BE with a AMD Radeon HD 6800 Graphics card (not integrated) to using a Intel Core i7 3770. As I have no knowledge of integrated graphics, my question is, what happens to the computing power when not using the HD4000 integrated graphics of the CPU (does it mean the CPU will run faster then it would if I relied on it?) Also what is better the CPUs inbuilt HD4000 or my Radeon Graphics card? I am mostly interested in terms of content creation: Using Adobe After Effects, 3D Rendering etc. Not too bothered about gaming performance. I will be using the spare parts of this build and older systems to make a second computer for network renders so what will be the advantages of keeping the Radeon with the current system for that?

• If i make a mail server can i send bulk email?

  - by Jake Smith

  I work for a small company and we have fallen into the fad of "email campains" a.k.a Junk mail. So far the company has gotten a subscriber list from our website, and paid a good chunk of change for a emailer program. The problem is, Our list has close to 4,000 people on it and growing. with gmail only allowing 100 emails per account through on SMTP and I am on a tight budget so I cant hire anyone else. I was thinking of doing a dedicated mail server off of the website server we have running in the office. Is it possible? to make emails on your own server, and then send it through your own SMTP? if it is, what software would I need and is if free or low cost at least. We run a WAMP server, i set it up just for information, but i could switch it to lamp or whatever if need be. Thank you for your time and youre answers

• Streaming video in Virtualbox jumpy

  - by Kevin

  I am trying to get Netflix to work on my Ubuntu netbook. I know it will not run in Linux so I am trying it in my Win XP virtual machine. It streams the video but the sound and video are out of sync and the video often freezes and jumps. I have tried Firefox, Chrome, and even IE. I am thinking my Atom N455 processor does not work well with virtualization. All other apps in the VM work fine. The only issue is streaming [YouTube is jumpy too].Does anyone know of Virtualbox settings I can try to possibly fix this issue or am I out of luck?

• update terminal title from standard output of long running command?

  - by Sam Hasler

  I'd like to change the title of a terminal window during a long running command (for example: git svn fetch) with values greped from the output, whilst still writing to standard output. Is this possible using named pipes or tee and xargs? I'm thinking something like git svn fetch | sed "s/^\(r\d*\).*$/ \"\\\033]0;\"\1\"\\\007\"/" | xargs -l1 echo -ne based on: http://tldp.org/HOWTO/Xterm-Title-3.html Update: getting this to work would be enough: (echo "r9" ; echo "r10") | sed "s/^\(r\d*\).*$/ \"\\\033]0;\"\1\"\\\007\"/" | xargs -l1 echo -ne Update 2: This almost does what I want. I see r10, but not r9: (echo "r9" ; sleep 1 ; echo "r10") | sed "s/^\(r[0-9]*\)\.*$/\\\033]0;\1\\\007/" | xargs -0 echo -ne

• ext4: error loading journal

  - by cloudyOutside

  I have an external hard drive with two partitions: A small FAT32 which is mostly empty and works fine and a large ext4 with tons of data, most of which isn't backed up. The ext4 is visible, but can't be mounted. I get an "error loading journal" error. The drive is a Western Digital Caviar Blue 500GB. Roughly 30GB of that is FAT32 and the rest is the ext4. The light on the enclosure turns red when reading from the bad partition. It was made by Cavalry. There wasn't any warning, but coincidentally, I've been thinking lately that I should get two large capacity drives for real backups. Is there anything that can be done? I'm not even sure I have enough storage to backup everything even if it is redeemable.

• What you'd need to setup BBS?

  - by raspi

  What I need to setup BBS nowadays? I'm thinking of BBBS or PCBoard (no telnet! too new technology). What I've thinked so far, I'd need: virtual machine which runs DOS and hook that virtual COM-port to somekind of virtual VoIP modem software somehow (is there any?). How you can call to it across internet? Can you use HyperTerminal straight with that virtual/real modem? Or will VoIP just garble the modem data and nothing will work?

• FTP error when doing file transfer

  - by Ernie

  I'm running vsftpd version 3.0.2 over FTPeS, and I'm having a bit of trouble with file transfers. It seems to work fine when I'm on the LAN, but not from an external IP address. I have the control port and data ports open on my server's software firewall and my router's firewall. When I'm using the service from an external IP address, it seems like sometimes a file transfer will complete, but it times out and I always get the client error: "426 Failure writing network stream". I've tried several clients. I'm thinking there is some sort of data sabotage either at the router or some server policy; maybe because I'm using passive ftp? Suggestions?

• external HDD with SATA & USB interface?

  - by Greg

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model. Preferably one of the name brands so I have a better change of finding it here or locally if possible. Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.
