• Removing BIOS Post Messages

  - by Steve

  I am working on a project where a standard x86 desktop system will boot and run a single program until it is shut down. I would like to remove all the bios post messages so that it looks a little more "finished" and cleaner when it starts up. I was hoping that there might by a standard implementation/terms to know about so I can avoid having to dig through every manual to see if there are options, or get some advice on a standard set of tools I should be using. I was thinking about getting a board that has an image that covers up the post messages until you press a key and trying to customize it to all black, but it's not clear if this is a good direction. I started looking for OEM motherboards but my searches were filled with standard commercial stuff, or seemed to be way to big for my toy project. What is the best way to go about removing all the bios post messages and just having a blank screen or "loading" message until OS loads?

• Comparing outgoing mail options, self hosted VS google apps in my situation

  - by Hoofamon

  I am setting up a small site that has the need to be able to programmatically send mail from time to time. Password resets and things like that. I'm already using google apps to handle my domains email, so now i'm left with the decision between setting up basic SMTP services on my server to send "password reset mails and things like that" OR instead to have the software use google apps to send mail. I like the google apps option as it's less stuff to worry about and seems to fit my needs, i'm trying to figure out what the downsides would be? Thanks for any thoughts

• Can I lvreduce after lvextend without losing the ext4 partition inside it?

  - by DrSAR

  In a botched attempt to move my root partition from one disk to another I have done the following: added new disk partitioned it with parted (part #3 is now almost totally filling the disk) initialized a physical volume $ pvcreate /dev/sdb3 Physical volume "/dev/sdb3" successfully created extended the volume group to include this new physical disk $ vgextend myvg /dev/sdb3 Volume group "myvg" successfully extended extended the logical volume (I think this is where I ballsed it up: I think I should have pvmove'ed stuff to the new pv in that group - can someone confirm?) $ lvextend /dev/mapper/myvg-root /dev/sdb3 I would now like to undo the lvextend and then proceed with the original plan of moving the content of the old physical volume over to the new physical volume. Can I reduce the logical volume (I have not yet touched the ext4 partition that sits in /dev/mapper/myvg-root with something like resizefs) without fear of damaging the ext4 filesystem? If so, how do I tell it to reduce by exactly the right amount? $ lvreduce --by-exactly-the-amount-occupied-by-PV /ev/sdb3 /dev/mapper/myvg-root

• Java and Sendmail HELO requires domain address

  - by ealgestorm

  I am trying to set up emailing from a java web application hosted on a linux server (Cent OS) in apache. Sendmail is working fine from the command line as root on localhost but when trying to send emails from the java web app (also on the same server from localhost) the following java exception is thrown. 501 5.0.0 HELO requires domain address EDIT: I have read that some people have found this is due to an incorrect hosts entry currently the hosts file contains 127.0.0.1 Centos-VPS localhost.localdomain localhost and i'm not sure what the Centos-VPS bit at the start is for but this is a clients hosted server so don't really want to break stuff EDIT see the RFC is helpful ... 501 Syntax error in parameters or arguments Now I know what the problem is! (note the sarcasm people.)

• How feasible is it to setup a FreeNAS to be more like a full install of FreeBSD

  - by mmccoo

  So I've been playing with FreeNAS over the last week, finally trying to get my act together and store my important files properly. I'm finding myself wanting to install and compile additional packages. pkg_add has been great for some things, but it appears that my install is rather crippled. make is missing. I installed gmake and linked make to that. math.h is missing as is sys/cdefs.h I thought these are part of any core unix/linux system? cc is missing though I've installed gcc45. I'm used to having just gcc. Sure I can create a link, but I'm not sure this is the proper thing to do. perl installed fine, but I can't add stuff with cpan. This is how I discovered 1,2, and 3. So my question is this: do I just need to bite the bullet and install a full FreeBSD? The web interface to FreeNAS is kinda nice

• Most efficient hard drive configuration for multitasking system

  - by user99391

  I hope I didn’t screw up the tile. Currently I’m using for my system 2x500g Raid0 system. I’m thinking about an upgrade but I got hold up by few questions. I need at least 100-120 gb for my system and apps and looking for a technological upgrade also. I've end up with 3 choices. Single 120 ssd (sata 6 drive) 2x60 ssd drives, but I've heard it's not possible. PCI ssd drive (~120gb). They all have very similar read/write values and prices but I was wondering if anyone could give some tips on which way to go. I run win7x64 and do a lot of multitasking(especially adobe stuff).

• Issues connecting VMWare VM to Windows 7 (host)

  - by MasterGberry

  I am on windows 7 trying to figure out why i cannot ping my computer or my VM from the other one, yet I am able to ping the router on both and other computers on the network. My desktop is running windows 7 64 bit and my vm is running CentOS 64 bit (which is what I use to test my web server stuff). At my school the VM has a dedicated IP and i don't have this issue, but I am home now and having issues trying to set this up behind my dumb router...I had already tried changing the VINC (i believe) to hide the vmnet1 and vmnet8 connections from the windows firewall and this seemed to have worked for like 5 minutes and then stopped... Any ideas? Thanks

• Are there any tutorials on web hosting at home? [closed]

  - by Arturs Lapins

  I want to host at home and I have done it before but I want to setup a server not just hosting on my windows 7. I know the risks and its better to just buy from hosting providers etc. I'm interested to host at home and I can't find any okay tutorial using unix, ubuntu server or whatever is the best. I want to see how you can install your mail server and make it work on your host and also ftp and all that interesting stuff. You people got any links or what?

• Books or other materials to overcome Linux learning curve?

  - by Marek Osvald

  I was born in 1989 and am an active Windows user since 1993. I've always struggled with Linux, not being able to configure the system the way I would like, snooping through blogs and forums for answers, never actually overcame the barrier. The books I've seen and read are either completely command line oriented (and don't get me wrong it's awesome to know this stuff when you're working on a server for example) but seems rather impractical to me on a desktop computer that's partially my development environment. The other kind are user manual describing step-by-step the controls of simplest applications like the Calculator, totally useless to me. What would you recommend for a programmer who needs to learn how to work with Linux but already knows the basics? What materials did you use to learn how to start with Linux?

• Alternative to Canned Response in Gmail

  - by Stuck

  I have a mailbox that i share with a colleague. We want a good way to store templates for e-mails that we send often like answers to common questions and so on. We have tried to use Canned Response to store this templates but that GUI really sucks and is kind of unusable for other things then signatures and stuff. Is anyone aware of a good alternative to this? We need to be able to share this templates. So it must be stored "in the cloud". We want "as easy access" as possible directly in gmail. A firefox plugin would be fine since we both use Firefox. We use both Mac and PC so the solution must be cross-platform. Anyone have any ideas on how to solve this?

• How to remove the pause during JBoss 5.1.0 GA boot between ProfileServiceBootstrap and AnnotationCreator?

  - by rrc7cz

  I've managed to strip down my JBoss profile enough that it boots in 1.5 minutes. I started with the web profile and started pulling out stuff I didn't need. The bulk of my boot time can be seen here: ... 15:21:51,890 INFO [ProfileServiceBootstrap] Loading profile: ProfileKey@86d597[domain=default, server=default, name=np] 15:22:55,406 WARN [AnnotationCreator] No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent 15:22:55,578 WARN [AnnotationCreator] No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent ... Does anyone have any idea what JBoss is doing here for 1 minute? If so, is there any way to speed it up or skip it entirely? This is for developer instances, so boot time is quite important.

• Debian - no sound output

  - by Gogeta70

  So I've been trying for the last few days to get sound output on my Linux desktop. The onboard audio is Intel HD Audio ICH9, but I couldn't get Alsa to even detect it, so I disabled it in BIOS and installed a PCI card - a Dynex DX-SC51. Searching around, I found that it needed the Alsa driver for ice1724, so I installed all the stuff for that. Now, the system detects my sound card, but I can't get any audio to play out of it. Here's some information: root@debian:~# lspci | grep audio 02:01.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01) root@debian:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ICE1724 [ICEnsemble ICE1724], device 0: ICE1724 [ICE1724] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: ICE1724 [ICEnsemble ICE1724], device 1: ICE1724 IEC958 [ICE1724 IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 I've been trying various solutions found on Google for a few days now and I'm getting nowhere. Hopefully someone here can point me in the right direction. Thanks.

• Moving the home directory to a new drive

  - by Mellowcandle

  I have no more space left on my hard-drive. So I bought a new one and I would like this hard-drive to be the home folder. I thought of copying all the stuff I have on the home folder to the hard-drive partition. and creating a symbolic-link from ~ to there. The problem I have is that I can't really delete the home folder while I'm logged in as the current user. Is there a way to log out, and log in as root in Linux Mint? I want to be able to do this without a live-CD solution.

• MongoDB PHP EC2 Setup Configuration

  - by nathansizemore

  I am new to web development and server set up. I am looking for some advice or a link to a tutorial on setting up a production system up. Right now, I have a server (Ubuntu, Apache, MongoDB, and PHP). It receives a request, PHP queries Mongo, and PHP sends out the requested data. How do I make that work with more servers? I've read that you can make a cluster of a primary and two slave nodes which work as separate servers running Mongo, but do those also run PHP? Or is the primary the only one running the PHP? I have read some docs on Mongo site and a video of someone from 10gen going through it, but they are geared towards people that seem to already understand this stuff, I have no idea and need to start from a beginning stage. If anyone can help me understand where PHP (Acting as my API) lives in these clusters, that would be greatly appreciated! Thanks in advance for any help!

• Hardware advice for bitmap / openGL image processing server?

  - by pdizz

  I am trying to work out a build for a processing server to handle bitmap processing as well as openGL rendering for chroma-keying images and Photoshop automation. My searches here and on Google have turned up surprisingly few results, and seeing that there aren't tags for bitmap or image processing I take it this is a specialized application. The bitmap processing is very cpu-intensive while the chroma-keying and Photoshop stuff is gpu-intensive. I doubt this is a case of over-optimization as our company batches thousands of images a day (currently on individual workstations) and any saving in processing time and workstation down-time would be beneficial. Does anyone have any experience with this type of processing server? Any special considerations that would go into a build like this or am I over-thinking it?

• How do I image my hard drive for backup? Or do I just need to backup the files?

  - by NoCatharsis

  I have never imaged a hard drive, so I don't know what software to use or how to prepare my system for imaging. Is this the best way to backup? In the past, I've always just kept a copy of my important files on an external drive and in Gmail or DropBox for smaller stuff, but it would be nice to just take one image and restore from that if something ever goes wrong. Thanks for the help. EDIT: I'm sorry, I forgot to mention the OS. I would like to do this for my home and work computers, which are Vista and XP respectively. And actually I'm about to upgrade to Windows 7 at home, so details on that would be appreciated too.

• dell E6500 laptop will not hibernate/standby

  - by Mark Schultheiss

  I am using a Dell E6500 laptop with windows XP on it, it was originally tagged/installed with Windows Vista. My issue is, when I close the lid, it will not either Hibernate or Standby. If I close the lid with either of these options, I then have to startup from scratch, and anything I had open is not open. I just want to close the lid, have it keep what I have running, not use power util I open the lid again and start it up (with the stuff still open I had open of course). Suggestions?

• Web-Server directory permissions

  - by MLS

  Hello All, I would like some help understanding web-server directory permissions. Apache, CentOS, PHP, Mysql Example, I have multiple sites in /var/www/html They are in paths like: /var/www/html/www_domainname_com inside each site I might have a path like /lib/mysql/ like PHP connect stuff, database config, etc. What should me permissions be so that someone cannot just browse to that directory? Should I just .htaccess them? I have apache:apache as the owner of all my web directories. Can I prevent someone from crawling certain directories of my web-server? I have a robots.txt, but what is to say the crawler obeys it? So to sum up: 1. What is the best owner/permission set for my sensitive files that the web-server or php or mysql needs, but I dont want people browsing to? Can I prevent straight out crawling of portions?

• Logins with only HTTP - are they as insecure as I'm thinking?

  - by JoeCool1986

  Recently I was thinking about how websites like gmail and amazon use HTTPS during the login process when accessing your account. This makes sense, obviously, since you're typing in your account username and password and you would want that to be secure. However, on Facebook, among countless other websites, their logins are done with simple HTTP. Doesn't that mean that my login name and password are completely unencrypted? Which, even worse, means that all those people who login to their facebooks (or similar sites) at a wifi hotspot in public are susceptible to anyone getting their credentials using a simple packet sniffer (or something similar)? Is it really that easy? Or am I misunderstanding internet security? I'm a software engineer working on some web related stuff, and although at the current time I'm not too involved with the security aspect of our software, I knew I should probably know the answer to this question, since it's extremely fundamental to website security. Thanks!

• Roaming Profile to act as a redirected folder? Dropbox in roaming profile is also causing slow login/logou

  - by user147069

  As title, what I'm wondering to know is .. if the roaming profile with Windows 2008 R2 Server (I'm talking about V2 profile - Windows7/Windows8) can work as a redirected folder (it can be done with the Desktop, Contacts, Download, AppData, My Documents). The roaming profile is copied at each login (server - client) and at each logout (client - server). This is causing slow login and logout for huge roaming profile. I can't stop the usage of roaming profile since the environment is a School with 1000 users. But I have big issues with users who populate the profile path (which is mapped on "User's File" under Windows7/8) with other stuff than the already redirected Desktop and My Document. A typical problem is given by the Dropbox folder... Any solution?

• How do I enable subfolders in Dovecot?

  - by yarun can

  In the past I was able to drag and drop my folder with subfolders (local emails) into my imap accounts inside Thunderbird. Now I moved to my own vps and its running Dovecot. So far so good with emails. Today I wanted to copy some folders with messages again but I realized that it does not let me copy to folders. I can drag and drop individual emails into some folders in Imap however folders stuff does not work. I am not sure what this feature is called. The previous email servers might be using some other imap server so I am really not sure what it might be even called. Is this a Dovecot or Thundenbird thing? If it is a Dovecot feature how I enable it on my server? Dovecot is running on Debian Wheezy 64 bit vps thanks

  - by Arsheep

  I have a old computer, and I want to buy a big LCD. The best I've found so far is Viewsonic's 24" LCD TFT monitor. So will it run without any problems, or do I need to upgrade the video cards or something as well? The computer is not too old: it has P4 board and celeron processor, with 128 graphics memory. And in display properties, it says that the maxium that I can use is 1280 x 1024 resolution. I am noob hardware-wise, so need help on this stuff. Thanks
