• Is a Hyperthreaded CPU more powerful and more efficient than a Dual-core CPU? [closed]

  - by user1811864

  which computer to choose with Pentium processor hello they are getting rid of the old computer equipment in the office and i have to choose the computer to take home i get first choice to pick. -15 inch lcd screen 4 gb of ram core 2 duo dual Core E8400 3.00 GHz dvd writer windows vista/ linux -15 inch crt monitor with 2 gb ram and pentium 4 2 ghz single core HT technology windows xp hardisks both 250 GB my friend is telling me to choose the second one Pentium single core HT because he told me it runs faster becuase of HT technology and cooler and consumes less current electricity so it wont get overheated because it has HT technology so it's high definition for encoding and watching HD movies and HD sound and is like a gaming pc to play internet games. And also he said the dual core 8400 runs at 3 ghz compared to the 2 ghz so it heats very much because of the two extra cores so it takes more current raising electricty bills and is not good for gaming and watching HD movies and internet flash animations and games because of getting heated everytime. And he wants to choose and take the E8400 because he has air conditioning at home so it will be safe from heating. So which one computer should i take is it really faster because of the HT High definition technology and will i be able to play internet flash card games better and watch good HD movies Youtube etc and play all the music and songs.

• Migrate openldap users and groups

  - by user53864

  I have an OpenLDAP server running on one of my ubuntu 8.10 servers. I used command-line only for OpenLdap installation and some basic configurations, everything else I'll configure with the Webmin gui tool. I'm trying to migrate to ubuntu 10.04 and I was able to migrate all other servies, application and databases but not the ldap. I'm an ldap beginner: I have installed OpenLDAP server and client on ubuntu 10.04 server using the link and used the following command to export and import ldap users and groups To export from 8.10 server slapcat > ldap.ldif To import to 10.04 server Stop ldap and slapadd -l ldap.ldif and Start ldap Then I accessed Webmin and checked in Ldap users and groups and I could see all the users and groups of my old ldap server.Whenever I create an ldap user from the webmin(in 8.10 or 10.04) a unix user is also created with the home directory under /home. But the imported users in 10.04 from 8.10 are not present as a unix user(/etc/passwd). How could I make the ldap users available as a unix user, is there any perfect way to export and import?. I also wanted to check the ldap users from the terminal that if password is exported properly but I don't know how to access the ldap users which are not available as unix users. On 8.10, I just use su - ldapuser and it is not working in the 10.04 as unix users are not created for the exported ldap users. If every thing works fine then the CVS works as it is using ldap authentication. Anybody could help me?

• Slow Local Network, Windows 7, Snow Leopard, WiFi/Wired

  - by WerkkreW

  I am experiencing really poor local network performance in my home. I was recently using a Linksys WRT54G Router with DD-WRT on it, and a couple comparable Linksys-G PCI cards for connectivity but decided to upgrade hoping it would help with my performance issues. The computers in my house are connected as follows: Comcast Business Class Commercial 25mbps/10mbps (Verified) D-Link DGL-4500 Wireless N Router Windows 7x64 - D-Link DWA-552 Wireless-N Windows 7x64 - D-Link DWA-552 Wireless-N Mac Mini 10.6.2 - AirPort Extreme N Playstation 3, Hard Wired Xbox 360, Hard Wired Essentially the problem is very specific. Web browsing and uploading/downloading files from the internet is fine, more than fine. But if I want to say, Stream a video from one of my Windows 7 computers to my PS3, or copy a large video file between either of the PC's or the Mac, I get a consistent 500-900Kbps throughput at the high end. If I open my network browser, or try to browse my homegroup the response time is horrible. Both of my Windows computers are showing Strong wireless signals with a connection speed of 300Mbps. I know I can never expect to achieve anything near those speeds, but 500Kbps? Here is what I have tried so far: Enabled Single mode N-only and N/G Only on router WPA2 with AES Encrpytion Disabled "Remote Differential Compression" in Windows 7 Disabled TCP "Auto-Tuning" Used other software for file copies such as "Teracopy" I am at the end of my rope. Unfortunately I live in a 75 year old home with plaster walls, so hard-wiring my entire house isn't really an option I can handle right now. Any ideas to help me get decent speed when transferring files across my network would be greatly appreciated.

• Web browsing through SSH tunnel gets stuck/clogged

  - by endolith

  I use tools like Tunnelier to log into my home Tomato router through SSH, and then use it as a proxy for web browsing, tunnel for Remote Desktop/VNC, etc. Most days it works great, but some days every page I try to view gets stuck, like the tunnel is clogged. I load a web page and it seems to be loading, then stops, with the little loading icon spinning and nothing happening. I refresh the page, I reboot the router, I reboot the other computers on my home network and turn off any bandwidth-hogging services on them, I've turned on QoS on the router to prioritize SSH. I don't understand what's getting stuck. Rebooting or disconnecting/reconnecting the SSH tunnel improves responsiveness for a minute, but then it gets clogged again. It also seems to help if I don't do anything on the tunnel for a few minutes, then it will be responsive for a bit and then get clogged again. Trying to open a terminal console from Tunnelier is also unresponsive, so it's not just a web browsing problem. Likewise, connecting to http://192.168.1.1 in the browser (to the router's web config through its own tunnel) is also slow/laggy/halting. The realtime bandwidth reported by the router is nowhere near my DSL connection's limits, though it does show big spikes during the laggy times, and the connection is responsive when it shows low bandwidths. How do I troubleshoot something like this?

• Freebsd jail for an small company - checklist - what shouldn't forget

  - by cajwine

  Looking for an checklist for an "small company freebsd/jail server". Having pretty common starting point: FreeBSD jail (remote/headless) for the company: public web, email, ftp server, and private (maybe in the future partially public) wiki (foswiki) 4 physical persons, (6 email addresses) + one admin - others will never use ssh) have already done usual hardening on the host side (like pf, sshguard etc). my major components are: dovecot, exim, apache22, proftpd, perl5.14. Looking for an checklist, what I shouldn't forget. My plan: openssl self-signed certificates for exim, dovecot and proftpd (wildcard keys) openssl self-signed certificate for apache (later will go for "trusted-signed" key) My questions are: is is an "good practice" having one pair of wildcard SSL-certificates for many programs? (exim, dovecot, proftpd) - or should I generate one key for each service? should I add all 4 persons as standard (unix) users, or I should go with virtual users? Asking because: have only small count of users, and it is more simple to configure everything (exim, dovecot) for local users ($HOME/Maildir), plus ability to set $HOME/.forward/vacation and etc. is here some (special) things what I should consider? (e.g. maybe, in the future we want setup our own webmail - will make this any difference?) any other recommendation? Thank you, hoping that this question fit into the http://serverfault.com/faq under the: Server and Business Workstation operating systems, hardware, software Operations, maintenance, and monitoring Looking for an checklist, but please explain why you're recommending it. See Good Subjective, Bad Subjective. related: What's your suggested mail server configuration for a FreeBSD server?

• mount multiple folders with nfs4 on centos

  - by microchasm

  I'm trying to get nfs4 working here. Machine 1 (server) I have a folder and in it 2 other folders I'm trying to share independently. /shared/folder1 /shared/folder2 Problem is, I can't seem to figure out how to mount the folders independently on the client. (Machine 1 - server) /etc/exports: /var/shared/folder1 192.168.200.101(rw,fsid=0,sync) /var/shared/folder2 192.168.200.101(rw,fsid=0,sync) ... exportfs -ra (Machine 2 - client) /etc/fstab: 192.168.200.201:/folder1/ /home/nfsmnt/folder1 nfs4 rw 0 0 ... mount /home/nfsmnt/folder1 mount.nfs4: 192.168.200.201:/folder1/ failed, reason given by server: No such file or directory The folder is there. I'm positive. I think there is something simple I'm missing, but I'm totally missing it. It seems like there should be a way in fstab to tell nfs which folder on the server I want to mount. But I can only find references to what looks like a root mount point (e.g. 192.168.1.1:/) which I assume is handled by exports on the server. But even with the folders set up in exports, there doesn't seem to be an apparent way to pich and choose which gets mounted. Is it not possible to mount separate folders from the same server to different mount points on the client? Any help appreciated.

• Custom Domain for Google App Engine and Google Apps

  - by Kevin

  I have set up and configured Google App Engine and Google Apps to use my custom domain with a cname 'www'. I have configured my DNS (via fasthosts.co.uk) with the cname and pointed it to ghs.google.com. I can access the website using the google app engine domain at capel-y-crwys.appspot.com but I can't access it via my custom domain www.capelycrwys.org.uk. I have allowed several days for propagation of the DNS etc. The really strange this is I can access the app via my custom domain when I use the web browser on my Android mobile phone. I can't access the app via my custom domain from my home internet connection, my work internet connection or a friends internet connection. I tried a few online web proxies and I can access the app via the custom domain. I posted this question on the google forums code.google.com/appengine/forum/?place=topic%2Fgoogle-appengine%2FfUP-G_0FKE4%2Fdiscussion and a commentor has said he could access the app via the custom domain. So why can't I access it direct via my home internet connection etc? I've tried loads of google searching and even found a similar sounding post here on serverfault serverfault.com/questions/208461/custom-domain-name-server-not-found-google-app-engine-and-google-apps but it doesn't have an answer that helps me.

• Why does my microwave kill the Wi-Fi?

  - by Ohlin

  Every time I start the microwave in the kitchen, our home Wi-Fi stops working and all devices lose connection with our router! The kitchen and the Wi-Fi router are in opposite ends of the apartment but devices are being used a little here and there. We've been annoyed by the instability of the Wi-Fi for some time and it wasn't until recently we realized it was correlated to microwave usage. After some testing with having the microwave on and off we could narrow down the problem to only occurring when the router is in b/g/n mode and uses a set channel. If I change to b/g mode or set channel to auto then there is no problem any more...but still! The router is a Zyxel P-661HNU ("802.11n Wireless ADSL2+ 4-port Security Gateway" with latest firmware) and the microwave is made by Neff with an effect of 1000W (if this information might be useful to anyone). There is an "internet connection" light on the router and it doesn't go out when the interruption occurs so I think this is only an internal Wi-Fi issue. Now to my questions: What parts of the Wi-Fi can possibly be affected by the microwave usage? Frequency? Disturbances in the electrical system? How can setting Auto on channels make a difference? I thought the different channels were just some kind of separation system within the same frequency spectrum? Could this be a sign that the microwave is malfunctioning and slowly roasting us all at home? Is there any need to be worried? Since we were able to find router settings that cooperate well with our microwave's demand for attention, this question is mainly out of curiosity. But as most people out there...I just can't help the fact that I need to know how it's possible :-)

• Can't access WordPress blog after host changed IP address of server

  - by John

  My host changed servers and all websites now have a new IP address. I have the same domain name and I assume the host runs the same nameservers, though my host and domain name provider are different. Notes: I never entered a Name or description under General/Settings for my blog. I left them both blank. That is when I could log into it. The wp-config file, has localhost entered rather than a specific IP. Again this has always been the case and my host never advised otherwise. I can get into cPanel by simply putting the newly advised IP in front of /Cpanel. However, I can not reach the admin panel of my WordPress blog (version 2.8.2). I had been loggin into it via http://xx.xx.xxx.xx/~example/blog/wp-login.php. My host suggested to simply insert the new IP in place of the old one. I still get the error message: 404 Not Found The server can not find the requested page: Apache/2.0.63 (Unix) mod_ssl/2.0.63 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.12 Server at 74.50.108.14 Port 80 I followed some tips on a question on Stack Overflow of a similar nature. I have logged into phpMyAdmin and found the wp-options table and searched for SELECT * FROM `wp_options` WHERE `option_name` IN ('siteurl', 'home') Only option ID 39 came up and the results are: Home has optionvalue http://example.org siteurl has optionvalue http://example.org/blog Both of which appear correct. Is there any part of the MySQL tables where I can change an actual IP address? Or is there something else you can advise?

• Permissions in OS X for iTunes library with multiple users

  - by John

  I currently have a lot of music on an external drive and my iTunes set up from there. However, periodically, when the external drive isn't connected, iTunes will default back to the library location of my home directory user path. I don't want to mess with an external drive, as my Mac's HD is large enough to house the music collection. However, I have 4 family members – all with their own logins – using this same gob of music. I don't want four copies of the library, only one with all libraries referencing it. So, what I want to do is: Move all music files to a shared directory at /Macintosh HD/users/music. I created this directory and adjusted permissions, so all four users can read and write to this directory. Get all four accounts to reference this library instead of the external or local home locations I am hoping I can just check the box to keep library organized in my account, which is the admin and let iTunes move it all. Then delete current libraries for each account and re-add from the new shared location. Will the iTunes organization process cause permissions issues either by setting permissions to all the files access to my account only or write permissions or any other 'gotcha'? I am having a hard time coming up with a smooth solution that won't break everything and cause me to have mega duplicates or access issues. I would prefer not to do any XML library file editing if possible. Am I dreaming?

• Strange ssh key issue

  - by user55714

  Scenario 1. I am doing this from /home/deploy directory I am trying to set up ssh with github for capistrano deployment. this has been an absolute nightmare. when I do ssh [email protected] as the deploy account I get Permission denied (publickey). so may be the key is not being found, so If I do a ssh-add /home/deploy/.ssh/id_rsa Could not open a connection to your authentication agent. (i did verify that the ssh-agent was running) If I do exec ssh-agent bash and then repeat the ssh-add then the key does get added and I can ssh into github. Now I exit from the ssh connection to my server and ssh back in and I can't ssh into github anymore! Scenario 2 if I login to my remote server and then cd into my .ssh directory and ssh into github then it all works fine I guess there is a problem with locating the key and for some reason the agent isn't funcitoning correctly. Any ideas? Her is a pastie with more details..my .bashrc, permissions etc. http://pastie.org/pastes/1190557/

• IIS 7, FastCGI, PHP and custom php.ini files

  - by Marlon

  I'm running PHP 5.3, FastCGI, and IIS 7 on Windows Server 2008. I have a site which I would like to configure its own php.ini settings for but things aren't working as expected. I am following the tutorial located here. This is what I have done so far: 1) Configured a new website with it's own AppPool. 2) Selected PHP 5.3.6 from the PHP Manager available on the website home on IIS (not the web server home which sets the global version of PHP) 3) Added the following lines to the section of the applicationHost.config file located at system32/inetsrv/config <application fullPath="C:\Program Files (x86)\PHP\v5.3\php-cgi.exe" arguments="-d open_basedir=C:\inetpub\wwwroot\kickasswebsite.com" maxInstances="4" idleTimeout="300" activityTimeout="30" requestTimeout="90" instanceMaxRequests="200" protocol="NamedPipe" queueLength="1000" flushNamedPipe="false" rapidFailsPerMinute="10"> <environmentVariables> <environmentVariable name="PHPRC" value="c:\inetpub\wwwroot\kickasswebsite.com" /> </environmentVariables> </application> 4) I then create a php.ini file located in C:\inetpub\wwwroot\kickasswebsite.com (the location of the root of the website) register_globals = on 5) I then run test.php which simply outputs everything the method call to phpinfo() returns. At this point, I observe that the global setting for register_globals = off (as it should be), but the local setting for register_globals = off, even though I specified it differently in the php.ini file I created at the root of the site. Furthermore, I see these settings in the output of the php.ini Configuration File (php.ini) Path C:\Windows Loaded Configuration File C:\Program Files (x86)\PHP\v5.3\php.ini Scan this dir for additional .ini files (none) Additional .ini files parsed (none) What am I messing up on, or is there a different way to go about this?

• Setting up VPN with Snow Leopard Server and Linksys router

  - by SueP

  I'd like to get VPN going so I can log in to the office securely from home. I'm using Snow Leopard machines everywhere, and currently have Airport Extremes set up at home and at the office. I have a mac mini with Snow Leopard Server that I'm going to move to the office to act as my server. I just bought a Linksys 4-port router because it says it does VPN (model RVS4000). My problem is, I don't have a clue how to set this thing up, and the more reading I do, the more confused I get. Do I need two of these routers, one at each end? My laptop and iPad claim they can do VPN, so I was assuming I only needed one VPN router? At this point, I literally don't know what questions to ask, or where to plug this thing in. Presumably, between the modem and the airport, but...? If somebody can walk me thru some really basic setup, I'd be very grateful. Right now, I feel like going outside and screaming for a while. But that might attract the local cougar, and after the prints I saw on the arena this afternoon, I don't want to draw its attention. :-)

• Configure linux machine as bridge/switch and end device

  - by leemes

  At my home, I have two desktop PCs in two rooms. The router / DSL modem is in one of these rooms. Now I want to configure a home server (having 2 LAN ports, running 24/7) in the corridor between the two rooms, using only one LAN cable at each door. This gives me the following physical configuration: (door) (door) .----/-/----. .-----/-/----------._ FritzBox | | | .----´´ DSL Router PC1 Server | PC2 As just said, the server has 2 network interfaces and is running Ubuntu. What I need now is a network configuration which enables both the server and PC1 to connect to the router. I think the server needs to serve as a bridge or switch. Currently, all computers are configured having static IP addresses. If I'm understanding it correctly, a bridge / switch doesn't have its own IP address, but as the server needs to be configured as an own end device, it needs to have one. My first question is, do I have to configure both interfaces separately, giving both the same static IP address? My next question is, how do I bridge the two physical networks into one? I have basic understanding (but am always confused again and again) of bridges and switches, but I don't know how to configure it in software. I only know that it's possible to do so :) The third question is: Is it possible to configure this in a way that network packets from/to PC1 to/from the router only go through hardware or only consume low CPU in the server? Can you help me? Thanks in advance!

• Advice on Computer Specs for overall development/general use machine

  - by Ender

  At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.

• How can I make grub2 boot into Windows 7?

  - by Grzenio

  I had Windows 7 installed on my system, then I installed Debian testing with grub2 as its boot manager. Initially I couldn't see windows entry in grub at all, so I ran: aptitude install os-prober kcpuload update-grub Now I can see the entry, but when I select it I get only Win7 system restore, instead of the the real thing. Any ides how to make it work? EDIT: I tried the suggested approach to add a new file to /etc/grub.d, which generated an entry in grub.cfg, but it does not appear in the grub menu on boot :( I have this: grzes:/home/ga# cat /etc/grub.d/11_Windows #! /bin/sh -e echo Adding Windows >&2 cat << EOF menuentry “Windows 7? { set root=(hd0,2) chainloader +1 } And I have the following grub.cfg file: grzes:/home/ga# cat /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } insmod ext2 set root=(hd0,3) search --no-floppy --fs-uuid --set 6ce3ff31-0ef7-41df-a6f5-b6b886db3a94 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=640x480 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi set locale_dir=/boot/grub/locale set lang=en insmod gettext set timeout=5 ### END /etc/grub.d/00_header ###

• How do I share a complete XP disk so it can be seen from a Windows 7 system? (To move all files to a

  - by Ian Ringrose

  This should be easier! (both computers can see the internet etc so I know the network it’s self is working) I have a normal home network with a Windows XP machine on it and the new Windows 7 (64 bit) machine. So I can transfer the files to the new Windows 7 machine, I wish to share the complete disk (and all files) from the Windows XP machine and access them from the Windows 7 machine. Is there a step by step set of instructions for doing this anywhere? So fare I have: put both computers into the same workgroup put the windows 7 machine into work network mode so it can see the XP machine in the work group shared the XP disk as read only But when I try to access a lot of the folders on the XP disks, I am told I am not allowed to access them. (I was not asked for any passwords by the windows 7 machine when I accessed the XP machine. The XP machine just has its default account with no password set on it) The XP machine runs XP home and hence has "simple file shairing" turn on. So it seems that even if I create a admin account (with password) and connect with that account, it still comes in as "guest" on the XP machine. Chooseing to share the folder I want access to rather then the top of the disk drive seems to work, but is a pain as I need to share each user's folder with a different share name. If the new computer was not a laptop, I would just plug the hard disk from the old machine into it, but being a laptop I don't have that option.

• All network devices freezing when Airport Extreme Base Station is connected. Any ideas?

  - by Jon

  I've been troubleshooting this issue for a while, and through a series of events have it narrowed down to my airport extreme base station. I like this router, since I'm able to connect to IPV6 sites without any insane configuration (my alternate router is too old and doesn't support v6). My question is: Has anyone else had this issue, if so how is it resolved? If not, can you recommend a good IPv6 router? Here is how I came to the conclusion that it is the router: Devices: XBOX 360, HTC Incredible, Home-Built machine running FreeBSD, Home-Built machine running Ubuntu 10.04. 1.) Noticed freezing on Ubuntu Box. 2.) Noticed freezing on XBOX360 3.) Noticed freezing on HTC Incredible (only when connected to my network wirelessly). The above all happened at random times throughout the past few weeks. Over the last few days, I was playing XBOX and noticed that the XBOX and Ubuntu machines both froze. I picked up my phone, and it was also frozen. I reset all devices, power-cycled my router, and all was fine again. About two hours later, it happened again (I was playing Forza III, the XBOX froze; I went to the Ubuntu box and it was frozen; unfortunately, the HTC phone was not connected wirelessly, and the FreeBSD box was turned off). I can't even begin to imaging what a router could be doing to freeze devices with such differing hardware/software/OS, and I feel absurd for coming to this conclusion, but I have nothing else. I hooked up my archaic Netgear router, and have had no problems since. :(

• Weblogic WLST classpath

  When I run the WLST script .sh script to set the env as follows why can't I see the updated path when I do echo?

• Are SATA II and SATA 3.0 Gbps compatible?

  - by Johnny Maelstrom

  I am trying to check that if I buy a new internal HDD it will work in the NAS I am buying. Currently I'm confused about naming schemes and once that is resolved whether there is compatibility. I will gladly author this question to be more general if there is not already an article helping with the confusion of SATA naming and standards. I see similar, but not identical questions and will accept this as a duplicate if thought as such. The specifications on the eCommerce site for the NAS says, "Controller Interface Type Serial ATA-150", the product home page for the manufacturer says, "Compatible with SATA and SATA II HDD". The specifications on the eCommerce site for the hard drives say, "Interface Type Serial ATA-300", the product home page for the manufacturer says, "Interface SATA 3.0 Gbps" Wikipedia says many things about different naming conventions, the closest being, "SATA II 3.0 Gbit/s, which was colloquially referred to as "SATA 3G" [bps] or "SATA 300" [MB/s] since 1.5 Gbit/s SATA I and 1.5 Gbit/s SATA II were referred to as both "SATA 1.5G" [b/s] or "SATA 150" [MB/s]). Therefore, they will operate with negligible differences between them." Are SATA II and SATA 3.0 Gbps the same? I feel I'm tantalisingly close to getting a definitive answer here before I purchase, but really want to clear up these naming schemes.

• Apache vhosts config: Host Name instead of IP Address

  - by Johe Green

  I have a domain (example.com) hosted at an external provider. I directed the subdomain sub.example.com to my ubuntu server (12.04 with apache2). On my ubuntu server I have a vhost setup like this. The rest of the config is basically apache 2 standard: <VirtualHost *:80> ServerName sub.example.com ServerAlias sub.example.com ServerAdmin [email protected] DocumentRoot /var/www/sub.example.com ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined WSGIScriptAlias / /home/application/sub.example.com/wsgi.py <Directory /home/application/sub.example.com> <Files wsgi.py> Order allow,deny Allow from all </Files> </Directory> </VirtualHost> When I enter http://sub.example.com in my browser my application shows up fine. But the domain is replaced by the IP address of my server. Do I have to configure my server somewhere else to deliver all its content under my domain sub.example.com?

• Which Revision Control Software to use for Personal Dropbox?

  - by wag2639

  I want to set up a sync repositiory that would be similar to Dropbox. Goals/Requirements: Free (Open Source very preferable) Linux host (probably Ubuntu) Windows/Mac/Linux clients Potential for multiple users with limited access (optional) Preferable easy, doesn't necessarily need to be automatic Revision control very preferable Basically, I want to be able to use multiple computers, possible with different OS's, and be able to access, use, and sync files across all of them. I also want to have a local copy of the repository for when I'm not connected to the network (as if I'm working on a laptop, I want to keep a local repository to keep revision and merge later with "master" repository). For example, I'm editing a few pictures on my laptop during the day outside of my network, but when I get home, I would like to sync the changes, including incremental changes, with my desktop at home. I would also like my roommates to be able to access and use this repository too but limit access to certain files. For example, I may want to use this to backup financial records but wouldn't want them to have access to those files. I'm a programmer and familiar with SVN but I know that wouldn't be the most appropriate since it doesn't handle binaries well and doesn't keep a local repository. I know better choices exist but I don't really know them well enough to choose the best one.

• XP VM not detecting USB keyboard or mouse from Windows 7 host

  - by Ian Kemp

  I've been using a Windows XP Pro VM (32-bit, SP3) for months on my work PC (Windows 7 64-bit) with no problems, with a PS/2 keyboard and a standard optical USB mouse. Today I copied this VM onto my home PC, which is also Windows 7 64-bit but with a G15 USB keyboard and MX518 USB mouse. For some reason the VM does not accept input from the keyboard or mouse, which makes it almost impossible to use. (Unity works but is not an option). Both my home and work PC are running VMware player 3.1.0. My keyboard and mouse show up as USB devices in the bottom-right of the VMware Player window, and if I click them I have the standard option to "Connect (Disconnect from host)". I have selected this option for the keyboard, and then the VM happily accepts keyboard input, but of course my host PC no longer does. It seems like VMware is seeing my keyboard and mouse as USB devices and not input devices. I've tried sending the keyboard input to the guest and reinstalling VMware Tools, but that achieved nothing. I'm certain it's a problem with the VM, and not the XP install, as I also can't use F12 to enter the VMware BIOS when the VM is powering up.

• Changing the prompt in telnet

  - by wim

  With some help from people on here, I was able to set a custom prompt in an ssh session (thanks!). Now I need to do the same in telnet, but I'm not sure of what syntax I could use for that. Basically the telnet prompt is just a > character, I need to modify it to something I can more reliably detect in automation jobs. Hope this makes sense. From inside telnet, trying to escape that command with a bang like !PS1=spam and !PS2=eggs did not change it. wim@wim-acer:~$ ssh [email protected] -i ~/.ssh/guest_nopassphrase -t "export PS1='Sending a custom prompt \w \$ '; exec sh" Sending a custom prompt ~ $ set HOME='/var/tmp' IFS=' ' LOGNAME='guest' PATH='/sbin:/usr/sbin:/bin:/usr/bin' PPID='1128' PS1='Sending a custom prompt \w $ ' PS2='> ' PS4='+ ' PWD='' SHELL='/bin/sh' TERM='xterm' USER='guest' Sending a custom prompt ~ $ telnet localhost <snip> Entering character mode Escape character is '^]'. > !set CONSOLE='/dev/ttyp0' HOME='/var/tmp' IFS=' ' LOGNAME='root' PATH='/sbin:/bin:/usr/sbin:/usr/bin' PPID='546' PREVLEVEL='N' PS1='\w \$ ' PS2='> ' PS4='+ ' PWD='/var/tmp' RESPAWN_COUNT='1' RESPAWN_LAST='0' RESPAWN_MAX='5' RESPAWN_TIME='5' ROOTDEV='/dev/sla1' RUNLEVEL='5' SHELL='/bin/false' TERM='linux' USER='root' > > Connection closed by foreign host Sending a custom prompt ~ $ Connection to 192.168.1.124 closed. wim@wim-acer:~$
