• CentOS Installation on a Cisco MCS 7800

  - by William

  Hello, I'm having some problems installing CentOS 5.5 Final (i386) Onto my server, a Cisco MCS 7800. The problem comes very early into the installation. When the welcome screen comes up ans gives you the option on how to boot into the DVD, Ill press enter to go into the graphical installer. The Screen will then have a blinking cursor in the top left of the screen and will never go away (I thought that it just might need time but I let it sit for over 5 hours.) I then booted into it again and tried using Linux Text thinking it was a problem with graphical installer. That didn't work, same problem. Then I tried a DVD of RHEL 5 and got the same problem, both graphical and Linux text. At this point i think its a hardware problem. The Server has 2GB of ECC RAM, 1 Pentium 4 CPU @ 3.06GHZ and 2 WD Hard Drives (80GB) Configured for RAID 0. ( Also there is a option in the BIOS for what OS type and that is set to Linux.) If anyone has any idea what is going on, it would be helpful. ================Edit================== ooshro, typing "text" doesn't change a thing. still stuck at the blinking cursor. I looked it up and its really the same thing as typing "linux text", which as stated in the first part of my question, i've already done.

• Outlook signature distribution tools ?

  - by HannesFostie

  Hi We are soon changing our corporate identity, and as such we will need to change our outlook signatures. However, being some 125 people, my colleague sysadmin and I don't want to go around changing these manually, and are thus looking for a good way to do this fully automated. Most of our desktops are XP, with the exceptional few running Win7. Most run Outlook 2007, some run 2003. Our environment is AD-centered, and most of the information will come from AD (telephone number, title, ...). The biggest problem I can see so far is that because we are bilingual (Dutch and French), there will be 2 versions of the signature, depending on what the person has as main language. People currently do not have anything in AD to distinguish this, but we could create a group for it, or perhaps add some sort of attribute. A cheap if not free tool would be great. eMailSignature could probably do most, if not all, of this for us but it's a rather expensive tool costing some 1250 euro. We just want to distribute the signatures, actual "management" is less important as job titles don't change all that much. Any tips are welcome!

• Need to restore emails that Outlook deleted from the mail server

  - by Mugen

  I wanted to use POP mail for my Yahoo mail account. So I went to the Yahoo mail settings and enabled POP feature. I installed Microsoft Outlook 2007 and added the settings for my Yahoo mail account. Then I performed a sync. I successfully received all the emails from Yahoo account into my pc. But when I logged into my Yahoo mail online, to my horror all the mails were deleted. It seems someone in Microsoft for some reason decided to keep the default setting unchecked for "Leave copy of messages on the server". This has been a very old account and I need to have all the mails also present on the mail server so I can access it anytime and future purposes. Is there anyway I can restore these emails on the server again? Any ideas how I can get it back to the way it was? I have been googling this for quite sometime now but I'm not able to find it. Any helpful suggestions are welcome. Thanks.

• How to restart boot Windows 7 after upgrading to a SSHD on SONY VAIO with recovery discs?

  - by Boris Okun

  The original HDD on my Sony VAIO still works, but has a damaged sector 0 and I was constantly prompted to replace the HDD because of the imminent failure. I created recovery discs as instructed, used a USB external HDD for complete back up (including Windows image back up). After installing the SSHD and using recovery discs to upload Windows and boot, I am getting the Windows welcome screen. Right after that, I'm getting the following message: Windows couldn't complete the installation. To install Windows on this computer, restart the installation. I have tried repeating the process many times all kinds of different ways and I still receive the same message. Also, when I tried to change to partitioning as the other option offered, I get the message: Windows Setup could not configure Windows to run on this computer's hardware. All troubleshooting for hardware and PCU came out solid. I tried to load the image back up from the external drive, but can't load the driver. The computer doesn't see it. Does anyone have a clue or has encountered something similar?

• Synchronize two directories on linux pc

  - by Gab

  I need a distributed filesystem (or a synchronization tool) that is capable of keeping a directory synchronized across 4 pc. My requirements are: offline access (data must be available offline on each pc) preserve execution rights: some files are marked executable on a linux partition. This flag should be replicated. efficient sync strategy: some of my files are 20GB, they are changed quite often, but in very little parts (Virtualbox images). Delta transmissions are welcome. efficient handling of space: no history for files, files shouldn't be copied to temp directories "just in case you break it". it must propagate deletions of files modification can happen in any of the 4 pcs, they should be propagated when other pc are connected. Other specs of my solution are: Sync is over a lan, the total amount of data to be synced is around 180GB, in some ten thousand files. Changes are small, but can happen in big files. At the moment i'm interested in a linux only solution. conflicts either don't happen or are solved with "last one wins" I haven't found any good solution. I've been trying: unison: it is the only one working at the moment, but during the hashing phase it hangs my pc for some minute, disk light steady on. Sparkleshare doesn't handle large files nicely. It keeps an history of all your changes that grows up indefinitely. They promise it will be fixed in next releases, but at the moment it still doesn't fit my needs. owncloud (keeps history of each file i change) coda ? (help! i couldn't set it up correctly!) git-annex assistant transforms all your files in symlinks and mark the original file as read only ("just in case you make a mistake while you modify it"!). Before you edit a file you have to issue a special command "git-annex unlock", that creates a local copy of the file, and you have to remember to lock it again if you want it synchronized. What to try next?

• Centos iptables configuration for Wordpress and Gmail smtp

  - by Fabrizio

  Let me start off by saying that I'm a Centos newby, so all info, links and suggestions are very welcome! I recently set up a hosted server with Centos 6 and configured it as a webserver. The websites running on it are nothing special, just some low traffic projects. I tried to configure the server as default as possible, but I like it to be secure as well (no ftp, custom ssh port). Getting my Wordpress to run as desired, I'm running into some connection problems. 2 things are not working: installing plugins and updates through ssh2 (failed to connect to localhost:sshportnumber) sending emails from my site using the Gmail smtp (Failed to connect to server: Permission denied (13)) I have the feeling that these are both related to the iptables configuration, because I've tried everything else (I think). I tried opening up the firewall to accept traffic for ports 465 (gmail smtp) and ssh port (lets say this port is 8000), but both the issues remain. Ssh connections from the terminal are working fine though. After each change I tried implementing I restarted the iptables service. This is my iptables configuration (using vim): # Generated by iptables-save v1.4.7 on Sun Jun 1 13:20:20 2014 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m tcp --dport 8000 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p tcp -m tcp --dport 465 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited -A OUTPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A OUTPUT -o lo -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 8000 -j ACCEPT -A OUTPUT -p tcp -m tcp --dport 465 -j ACCEPT COMMIT # Completed on Sun Jun 1 13:20:20 2014 Are there any (obvious) issues with my iptables setup considering the above mentioned issues? Saying that the firewall is doing exactly nothing in this state is also an answer... And again, if you have any other suggestions for me to increase security (considering the basic things I do with this box), I would love hear it, also the obvious ones! Thanks!

• Mac OS X in Virtualbox says "You need to restart your computer"

  - by humoeba

  I've been trying to figure out for the past week how to get Snow Leopard reliably running in a VM. Right now I am using VirtualBox, and it runs fine for a while, but every once in a while (happened 3 times in the last few hours) I get the "You need to restart your computer" message. Unfortunately, it hasn't even lasted long enough to finish installing the operating system yet. I first tried VMWare, which was a pain to set up. I got it running ok, operating system installed, with the guest tools. Every once in a while though, it just stops running. I click inside the VM, and there's no mouse. It doesn't respond to keyboard input either. I have to reset the VM to get a response. I'm wondering if this is the same error. This happens with both Workstation and Player. Here is the tutorial I used for VirtualBox: http://www.sysprobs.com/iboot-loader-virtualbox-install-snow-leopard Here's the tutorial I used for VMWare: http://bobhood.wordpress.com/2009/12/18/welcome-to-snow-leopard-mac-os-x-10-6-and-vmware-workstation-7/ I'm using an iso for Mac OS X 10.6.3. I have an HP Pavilion dm4 with an Intel Core i7 M640 running Windows 7; VT is turned on. Using VirtualBox 4.0.4 and VMWare Workstation 7.0.1 and VMWare Player 3.0.1 Does anyone know what might be causing this error or how I can fix it? Thanks.

• Exchange 2010 - Certificate error on internal Outlook 2013 connections

  - by Lorenz Meyer

  I have an Exchange 2010 and Outlook 2003. The exchange server has a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com. But there is a hindrance: the certificate provider (in my case Godaddy) requires that the domain is validated as being our property. Now it is not possible for an internal domain that is not accessible from the internet. So this turns out not to be an option. Create self-signed SAN certificate with an Enterprise CA is an other option that is barely viable: There would be certificate error with every access to webmail, and I had to install the certificate on all Outlook clients. What is a recommended viable solution ? Is it possible to disable certificate checking in Outlook ? Or how could I change the Exchange server configuration so that the public domain name is used for all connections ? Or is there another solution I'm not thinking of ? Any advice is welcome.

• Two screens hooked to one laptop

  - by mplacona

  Hi, I'm thinking of getting rid of my desktop, and using my (much better) laptop instead. I'm only wondering if I would be able to hook the two screens I have with it, so I'd end up with three screens. I've seen people doing it to desktops, but am not sure the same could be accomplished with a laptop. My laptop is a sony vaio, and it's got both a VGA output, and an HDMI output. It'd be great is I could simply hook two screens to it, and have three independent screens (not mirrored). on my desktop, I have pretty much the same thing, but with an extra DVI port. I connect the DVI to one screen, and the VGA to an older one. Trying to connect anything to the HDMI simply mirrors whatever is on the DVI (I've tried it a long time ago) So I was wondering if with the laptop I'd be able to do it, and end up with three independent screens. I don't know if there's anything else I could be using instead (i.e. any extra hardware), so recommendations are more than welcome. Thanks in advance, Marcos

• Offline productivity

  - by Frank Meulenaar

  On some days I'm commuting 2hs (oneway) in the train. I don't have any mobile internet nor is there always WiFi service in the train. Because of security reasons I can't do any work in the train so I'm trying to work on my geek time. I'm looking for general solutions on how to do this (I'm on FireFox/Windows but I don't think it matters) Email works perfectly with gmail offline. It syncs directly when online and remembers complicated stuff. So far I used the ScrapBook plugin to store an website. It works good, but I have to download my favorite news page every day again - I want it to sync as soon as possible. It would even be more awesome if I could click a page on my desktop and my laptop would sync as soon as it has the chance. (edit: maybe the autosave plugin for scrapbook can do this) Similarily, I use the Downloadhelper plugin to download youtube vids, but I'd like something that automatically downloads videos from a given channel. Any tips are welcome. So far my early morning schedule is: wake up, power on laptop, make coffee, power off laptop and leave within 10 minutes (enough time for GMail to sync) but I can imagine a system where my laptop stays on during the night (or boots before I wake (and makes me coffee :])).

• Dell Vostro Desktop error

  - by goldenmean

  Faced a strange situation at work today. We have people sitting at a table on opposite sides, with power cables underneath the table. This morning when the person sitting opposite to me banged his feet on ground, it disturbed the power cable to my PC and it turned-off. So when I turned it on, it says, "No boot device found" Press F1 to setup or F5 to perform test... There was no physical impact/crash/fall of the desktop cabinet, which could have crashed/damaged the hard disk physically. EDIT: The OS is Windows 7 So I tried to recognize it in the Bios setup, but even there it could not find the SATA disk that is connected to this machine. So then I opened the cabinet, removed the power supply and plugged it back again. Tried to reboot, same error, "Boot device not found" It is not recognizing the hard disk. Any ideas about what might be wrong? Hard-disk crash, OS Crash(But it doesn't even go to the point of loading the disk after the initial Bios execution, so doubt this...) Any pointers about how I should proceed to troubleshoot/solve this error are welcome.

• Basic connectivity issues between Win 7 and XP mixed wired/wireless network.

  - by Pulse

  Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either The Win 7 desktop or the VM's it alwats returns a destination host unreachable. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks

• Windows Explorer and UAC: run elevated

  - by syneticon-dj

  I am profoundly annoyed by UAC and switch it off for my admin user wherever I can. Yet, there are situations where I can't - especially if those are machines not under my continuous administration. In this case, I am always challenged with the task of traversing directories using my administrative user via the Windows Explorer where regular users do not have "read" permissions. The possible two approaches to this problem so far: change the ACLs to the directory in question to include my user (Windows conveniently offers the Continue button in the "You don't currently have permissions to access this folder" dialog. This obviously sucks since more often than not I do not want to change ACLs but just look into the folder's contents use an elevated cmd.exe prompt along with a bunch of command line utilities - this usually takes a lot of time when browsing through large and / or complex directory structures What I would love to see would be a way to run Windows Explorer in elevated mode. I have yet to find out how to do so. But other suggestions solving this problem in an unobtrusive way without changing the entire system's configuration (and preferably without the need for downloading / installing anything) are very welcome, too. I have seen this post with a suggestion for altering HKCR - interesting, but it changes the behavior for all users, which I am not allowed to do in most situations. Also, some folks have suggested using UNC paths to access the folders - unfortunately this does not work when accessing the same machine (i.e. \\localhost\c$\path) as the "Administrators" group membership is still stripped from the token and a re-authentication (and thus the creation of a new token) would not happen when accessing localhost.

• Linux Software RAID1: How to boot after (physically) removing /dev/sda? (LVM, mdadm, Grub2)

  - by flight

  A server set up with Debian 6.0/squeeze. During the squeeze installation, I configured the two 500GB SATA disks (/dev/sda and /dev/sdb) as a RAID1 (managed with mdadm). The RAID keeps a 500 GB LVM volume group (vg0). In the volume group, there's a single logical volume (lv0). vg0-lv0 is formatted with extfs3 and mounted as root partition (no dedicated /boot partition). The system boots using GRUB2. In normal use, the systems boots fine. Also, when I tried and removed the second SATA drive (/dev/sdb) after a shutdown, the system came up without problem, and after reconnecting the drive, I was able to --re-add /dev/sdb1 to the RAID array. But: After removing the first SATA drive (/dev/sda), the system won't boot any more! A GRUB welcome message shows up for a second, then the system reboots. I tried to install GRUB2 manually on /dev/sdb ("grub-install /dev/sdb"), but that doesn't help. Appearently squeeze fails to set up GRUB2 to launch from the second disk when the first disk is removed, which seems to be quite an essential feature when running this kind of Software RAID1, isn't it? At the moment, I'm lost whether this is a problem with GRUB2, with LVM or with the RAID setup. Any hints?

• How to implement a virtual server running Ubuntu inside a fileserver in windows?

  - by user541445

  I work in a company that has some limitations regarding their budget. They need client/server aplication. I can code the aplication, I've made mini tests on primordial applications that work. The thing is that they only have fileservers, and the application they need must be concurrent compliant, so the database must be in their local network (Fileserver is the only choice). So far, I have explored almost any option available, starting with: Desktop databases. Access (We have a license)(But concurreny is just not effective, besides it's a windows software, yuck). Sqlite (Nice, but since the information they manage is a lot, I've performed some concurrency tests with INSERTs and doing SELECTS at the same time). It fails, somehow it just stops inserting. Open office Base (I dismember a base office only to see that it was a file mode HSQLDB). I've tried, not concurrent at all. Etc (You name the Open source Desktop Database manager, and yes, I've tried that one.) Server databases Call me a stubborn person, but reading some server databases documentation say that their databases will work in a file mode. I've tried a lot of products. Postgres, MySQL, FireBird, H2, Derby, Oracle Express, IBM DB2 Express, etc. So, I really need a hand here, I've been doing this install/delete/depression thing with a lot of databases for 3 weeks, until I got with a crazy idea and I just came here to express it. So, my question comes down to this: Installing a light virtual OS software like Virtual PC and then installing in there a Server OS like an Ubuntu server inside that virtual software will work? Will it work 24/7 or when I close the virtual pc software? Will this work in a fileserver? Any suggestion, answer, critic to the place I work, crazy new concurrent database that will work in fileserver will be most than welcome.

• nginx proxying different servers for different subdomains

  - by The.Anti.9

  i just set up an nginx server. On the same computer as nginx, I have apache running on port 8000 (this was previously set up.) and I want no subdomain and the www. subdomain to go to the local apache instance. But i want the stuff. subdomain to link to my server where i keep all my miscellaneous files (pictures, documents, etc.), which is also listening on port 80 at the ip 192.168.1.102. I tried configuring it, but when i go to my domain, I just get the "Welcome to nginx!". Here's what I have: user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; include /etc/nginx/conf.d/*.conf; server { listen 80; server_name theanti9.com www.theanti9.com; access_log /var/log/nginx/access.log; location / { proxy_pass http://localhost:8000; } } server { listen 80; server_name stuff.theanti9.com; access_log /var/log/nginx/access.log; location / { proxy_pass http://192.168.1.102:80; } } } I'm not really sure what's wrong. Any suggestions?

• Utilities for finding x/y screen coordinates

  - by slothbear

  I have an application that needs the user to enter the x and y location of a couple of items on the screen. [Yes, this is crap and I'll replace it, but for now...] On Mac OS X, I'm using Snapz Pro X. When I choose to take a snap of a selection, the interface displays the mouse cursor location. This is OK for my personal use, but I can't ask users to buy a $69 program for this function. I thought I had a solution with the built-in program "Grab", but it reports the coordinates from the bottom left, and I need it from the top left. I don't have access to Windows; not sure what to use there. I've not even been able to come up with good search terms since mouse and coordinates and x/y are so common. Ideas are welcome there. Extra credit: same x/y finder for Linux. A Java program would be OK too, since the main application is in Java.

• KVM Hosting: How to efficiently replicate guests

  - by javano

  I have three KVM servers each with 1 guest VM, running directly on it's local storage, (so they are essentially getting a dedicated box worth of computing power each). In the event of a host failure I would like the guests replicated to at least one of the other hosts so I can spin it up there, until the failing host is fixed. I am curious about KVM cloning. I can clone a VM live or when it's suspended/shutdown. Obivously suspended VMs will naturally be quicker to clone but these three VMs comprise three parts of a single solution, so I don't want to ever have any one of them shutdown. How can I efficiently clone these VMs between servers? I have had a couple of ideas, but are these insane or, is there a better method I have missed for my scenario? Set up a DRDB partition between box 1 and 2 where VM 1 runs from, and so is replicated between box1 and box 2, repeat between box 2 & 3, and box 3 & 1 (This could be insane, I have never used DRDB only read about it) Just use standard KVM CLI clone options to perform live clones (I'm dubious about this because I don't know how long it will take and what the performance impact will be during) Run a copy of each VM on at least one other host, and have the guest on one host export it's data to the matching guest on another host where it can import that data, scripting this on the guest) Some of other way? Ideas welcome! Side Note These servers have 4x15k SAS drives in a RAID 10 so they aren't rocketing fast, and as I mentioned, each VM runs from the host's local storage, no NAS or SAN etc. So that is why I am asking this question about guest replication. Also, this isn't about disaster recovery. Guests will be exporting their data to a NAS over a VPN, so I am looking at how I can have them quickly spun up in a host failure situation.

• I am starting to think that Prevx.com isnt a legit site...but heres my long-winded question

  - by cop1152

  I apologize in advance for the long-winded post. I posted it all because I believe its informative and may be useful. Also, I posted my question at the end. Moments ago I was RDC to a file server in my home (from inside my home). I had opened Firefox and Googled for a manufacturers website. Immediately after clicking the link, Firefox abruptly closed. This seemed odd to me to so I checked the running processes and discovered d.exe, e.exe, and f.exe running. I Googled these processes on a different machine and found them belonging to a key-logger/screen-capturer/trojan called defender.exe, which according to the Prevx lives in c:\documents and settings\user\local settings\temp. (Prevx link http://www.prevx.com/filenames/147352809685142526-X1/DEFENDER32.EXE.html) Simultaneously, an obviously-spoofed Windows Firewall popup appeared on the server asking me to click ‘yes’ to update Windows Firewall. At this time I ended all rogue processes, emptied the temp folder, removed defender.exe from startup, and checked my registry and a few other locations. Before deleting Defender.exe I noted that it was created moments ago, just before Firefox crashed. I believe that I was ‘almost’ infected with this malware. I believe that it needed me to click the phony popup in order to complete infection because it wasn’t allowed to execute processes from the temp folder. After cleaning the machine, I restarted it and have been monitoring it for over an hour. I am debating on whether or not to restore the Windows partition (a separate physical drive from the data) or to just watch it for awhle. I should mention that, because of the specs on this machine, I do not run antivirus software, but I know it well and inspect it regularly. It is a very old Compaq with a 400mhz processer and 512mb of ram. I have a static IP and the server is in the DMZ running an FTP client and some HTTP server software. All files transferred to and stored on this machine are scanned for malware before transferring. Usually the machine only runs 19 processes and performs pretty well for its intended purpose. I posted the story so that you could be aware of a possible new piece of malware and how it acts, but I also have a question or two. First, over the last few months I have noticed that PREVX is listed at the top of most of my Google searches when researching malware, especially for new or obscure malware…and they always want you to purchase something. I don’t think they are one of the top AV companies, so it seems odd that they are always the top Google result. Does anyone have any experience with any of their products? Also, what sites do you rely on for malware researching? Recently, I have found it difficult to find good info because of HijackThis-logs and other deadend info cluttering up my searches. And lastly, besides antivirus, third-party firewall, etc, what settings would you use to lock down a machine to make it more secure in instances where a stubborn admin like myself refuses to run AV? Thanks.

  I have a user who edits technical materials. She uses MS Word's Custom Dictionary all the time for spelling; it has grown very large, and is now making spell check very slow. All of the advice I've read online says to disable the custom dictionary. This is an easy solution, but is not workable for the user, because she actually needs this dictionary. So, is there any way to optimize the custom dictionary and/or Word itself, so that a large dictionary file doesn't slow things down quite so badly? Many thanks. Update after suggestions: I ran contig on the file, and it reports just 1 frag, so that's not the issue I think. The file is 9.95KB -- 1,117 lines, each consisting of just a single word. I viewed the file using Notepad and none of the lines seems corrupted, strange, or overly long (no line seems to be over 10 chars or so). Both of your suggestions were helpful so I will upvote both; any further tips would be most welcome.

• Multiple Rails apps on same subdomain?

  - by Derek

  I recently decided to try out Rails. When working with PHP, I simply had all of my PHP projects in the same directory. For example, I may have http://ubuntu/app1, http://ubuntu/app2, etc. I created a subdomain for Rails (http://ruby.ubuntu), installed Rails and Passenger and everything is working. However, I may be wrong, but it looks like I can only have one Rails app per subdomain? My VirtualHost is as follows: <VirtualHost *:80> ServerName ruby.ubuntu ServerAdmin webmaster@localhost DocumentRoot /var/www/ruby/blog/public <Directory /var/www/ruby/blog/public> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all RailsEnv development </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> 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 </VirtualHost> All of my PHP and misc. files are stored in /var/www/main. I want to be able to store all of my Rails apps in /var/www/ruby. I tried changing DocumentRoot to /var/www/ruby, but I don't think it's as simple as that. When I browse to a Rails app's Welcome Aboard page and click on "About my application's environment," I get a 404 page, but when the DocumentRoot is set to the public directory, I get the expected result. I don't want to have to create a new subdomain every time I create a new project. Is there any way I can make it so I can store all of my apps in /var/www/ruby, and browsing to http://ruby.ubuntu will let me access all of my Rails apps there? That way if I want to create a new app, all I have to do is rails new app, no Apache .htaccess or VirtualHost configuration required.

• Gigabyte H55N-USB3: No video on HDMI

  - by newt

  I built a new PC with a Gigabyte H55N-USB3 / Intel Core i5 650. With a monitor plugged in the DVI port, everything works fine. I installed Windows 7 32-bit and enabled remote desktop connection. After that, I unplugged the monitor, plugged it into network and installed everything else (drivers, programs, etc) via RDP. However, when I try to use the HDMI port on my TV nothing appears. Neither during the boot, neither after Windows starts. The TV says there's "no signal" (if I remove the cable the message changes to "check cable"). The cable is new, and it is working fine with my home theater on same TV (by the way, it is the cable which came bundled with the home theater). Video driver is the latest from Intel site. Anyway, this shouldn't be the problem since there is no image during the boot. Any ideas or tips would be welcome. I'm googling around but found nothing useful, yet.

• I want to replace a number with successive numbers, starting at 1 and going up.

  - by Pär-Magnus Green

  I'm aware that this is something people can easily program, but I'm not familiar with those things, so I was hoping there was an easier solution. I've edited a large database of questions, including sorting, and ended up getting all the question ID's mixed up. I'm trying to do this in Notepad++, but any other suggestions are welcome. I'm wondering if there's a way to search for a string (ex. "Question[any number]") and replace the numbers with first 1, then 2, et.c. For clarification, this is how one question looks like: TriviaBot_Questions[3]['Question'][63] = "Acronyms: What does WTT stand for?"; TriviaBot_Questions[3]['Answers'][63] = {"Want To Trade"}; TriviaBot_Questions[3]['Category'][63] = 7; TriviaBot_Questions[3]['Points'][63] = 1; TriviaBot_Questions[3]['Hints'][63] = {}; and the next question, as is now, is not followed by 64. It might be 245 or 1029, and regardless of which number it is, I want it replaced with "previous number + 1", basically.
