• Best way to segment traffic, Vlan or subnet

  - by thebird

  We have a medium sized network of around 200 nodes and are currently in the process of replacing old daisy chained switches with stack-able or chassis style switches. Right now our network is broken up via subnet; production, management, IP, etc each on a separate subnet. Does anyone have an opinion on whether creating Vlan's instead of subnets would be more beneficial? Our general goal is to prevent bottlenecks, separate traffic for security, and to manage traffic with more ease.

• best app to stream movies over the web

  - by rashcroft

  Hi. I have an old box that I'd like to use as a private sever to stream movies off of. My upload speed is about 0.5/Mb/s, so I need something that compresses well. I'd like to be able to access these movies from anywhere, through the web, through some interface (maybe the divx web player? flash player? some other protocol?) Can anyone recommend anything good? (Using Windows XP) Thanks!

• Best Server Ghost-Like Tool For Windows

  - by John Dibling

  I'm looking for advice on which tool we should use to clone servers. In the short term, we will be cloning identical hardware but in the long run we may want to create one image and replicate that on a different class of machine. For example, as new servers are released from Dell, we will want to continue to use the same image we already made. Right now our servers are Windows (Server 2008 & Server 2008 R2), but moving forward we may need Linux support as well. Ghost Solution Suite 2.5 seems to be the canonical tool. Are there alternatives? Recommendations/reviews?

• What is the best vfat driver for FUSE?

  - by Vi

  FUSE filesystem list show some FuseFat and FatFuse. One is 404 not found, others is old, not buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself), but it looks too big for such task. Is there good vfat FUSE driver?

• The best way to hide data Encryption,Connection,Hardware

  - by Tico Raaphorst

  So to say, if i have a VPS which i own now, and i wanted to make the most secure and stable system that i can make. How would i do that? Just to try: I installed debian 7 with LVM Encryption via installation: You get the 2 partitions a /boot and a encrypted partition. When booting you will be prompted to fill in the password to unlock the encryption of the encrypted partition, Which then will have more partitions like /home /usr and swapspace which will automatically mount. Now, i do need to fill in the password over a VNC-SSL connection via the control panel website of the VPS hoster, so they can see my disk encryption password if they wanted to, they have the option if they wanted to look at what i have as data right? Data encryption on VPS , Is it possible to have a 100% secure virtual private server? So lets say i have my server and it is sitting well locked next to me, with the following examples covered bios (you have to replace bios) raid (you have to unlock raid-config) disk (you have to unlock disk encryption) filelike-zip-tar (files are stored in encrypted archives) which are in some other crypted file mounted as partition (archives mounted as partitions) all on the same system So it will be slow but it would be extremely difficult to crack the encryption. So to say if you stole the server. Then i only need to make the connection like ssh safer with single use passwords, block all incoming and outgoing connections but give one "exception" for myself. And maybe one for if i somehow lose my identity for the "exeption" What other overkill but realistic security options are available, i have heard about SElinux?

• Best practices for encrypting continuous/small UDP data

  - by temp

  Hello everyone, I am having an application where I have to send several small data per second through the network using UDP. The application need to send the data in real-time (no waiting). I want to encrypt these data and insure that what I am doing is as secure as possible. Since I am using UDP, there is no way to use SSL/TLS, so I have to encrypt each packet alone since the protocol is connectionless/unreliable/unregulated. Right now, I am using a 128-bit key derived from a passphrase from the user, and AES in CBC mode (PBE using AES-CBC). I decided to use a random salt with the passphrase to derive the 128-bit key (prevent dictionary attack on the passphrase), and of course use IVs (to prevent statistical analysis for packets). However I am concerned about few things: Each packet contains small amount of data (like a couple of integer values per packet) which will make the encrypted packets vulnerable to known-plaintext attacks (which will result in making it easier to crack the key). Also, since the encryption key is derived from a passphrase, this will make the key space way less (I know the salt will help, but I have to send the salt through the network once and anyone can get it). Given these two things, anyone can sniff and store the sent data, and try to crack the key. Although this process might take some time, once the key is cracked all the stored data will be decrypted, which will be a real problem for my application. So my question is, what is the best practices for sending/encrypting continuous small data using a connectionless protocol (UDP)? Is my way the best way to do it? ...flowed? ...Overkill? ... Please note that I am not asking for a 100% secure solution, as there is no such thing. Cheers

• Linux Best Practices

  - by Zac

  I'm a life-long Windows developer switching over to Linux for the first time, and I'm starting off with Ubuntu to ease the learning curve. My new laptop will primarily be a development machine: 6GB RAM, 320 GB HD. I'd like there to be 2 non-root users: (a) Development, which will always be me, and (b) Guest, for anyone else. I assume the root user is added by default, like System Administrator in Windows. (1) I'd like to mount /home to its own partition, but how does this work if I have two user accounts (Development and Guest)? Are there 2 separate /home directories, or do they get shared? Is it possible to allocate more space for Development and only a tiny bit of space for Guest in GRUB2? How?!?! (2) I'm assuming that its okay that all of my development tools (Eclipse & plugins, SVN, JUnit, ant, etc.) and Java will end up getting installed in non-/home directories such as /usr and /opt, but that my Eclipse/SVN workspace will live under my /home directory on a separate partition... any problems, issues, concerns with that? (3) As far as partitioning schemes, nothing too complicated, but not plain Jane either: Boot Partition, 512 MB, in case I want to install other OSes Ubuntu & non-/home file system, 187.5 GB Swap Partition, 12 GB = RAM x 2 /home Partition, 120 GB I don't have any bulky media data (I don't have music or video libraries, this is a lean and mean dev machine) so having 320 GB is like winning the lottery and not knowing what to do with all this space. I figured I'd give a little extra space to the OS/FS partition since I'll be running JEE containers locally and doing a lot of file IO, logging and other memory-instensive operations. Any issues, problems, concerns, suggestions? (4) I was thinking about using ext4; seems to have good filestamping without any space ceiling for me to hit. Any other suggestions for a dev machine? (5) I read somewhere that you need to be careful when you install software as the root user, but I can't remember why. What general caveats do I need to be aware of when doing things (installing packages, making system configurations, etc.) as root vs "Development" user? Thanks!

• Best way to use mod_rewrite to replace WordPress pages with static files

  - by David Moles

  Here's the situation: I've got an old WordPress installation that I'd like to archive as static files, but I'd also like to preserve old URLs. I've already created the static archive with wget and sorted out the filenames and links. Now I'd like to configure Apache to intercept requests for the old dynamic URL and replace them with the new static one, e.g.: http://www.example.org/log/?p=1234 or http://www.example.org/log/index.php?p=1234 should redirect to http://www.example.org/log/archives/1234.html I've tried adding the following to the VirtualHost config for example.org, but to no effect -- I just get the PHP page. RewriteCond %{REQUEST_URI} /log/ RewriteCond %{QUERY_STRING} p=([^&;]*) RewriteRule ^/$ http://%{SERVER_NAME}/log/archives/%1.html [R,L] I've enabled logging and I can see what look like other rules being applied, but not this one. None of my other guesses at match patterns for %{REQUEST_URI} seem to have any effect either (log, log/, log.*, even .*). I'm new to mod_rewrite and this is mostly cargo cult, so I'm pretty sure I've gotten it wrong. Anyone know what I should be doing here?

• Best VoIP VPS Location?

  - by ToiletOverflow

  Our office currently runs a few phones over a VoIP line. Through our VoIP provider, we have a virtual private server. We chose them as the VPS provider because the VPS came pre-loaded with all of the software that was necessary. However, I've discovered that I would rather manage the software myself and would prefer to work on a different platform. The primary reason that we have stayed with them is because as our VoIP provider, I presume that there is some advantage in call quality because they have "direct access to the PSTN", which I would presume is an advantage when it comes to call termination and overall call quality. My question boils down to: What is better from a call quality perspective? 1) A server located 20ms closer to us (60ms), offered by a different company. 2) The current server at the VoIP/SIP provider (80ms)

• Best server OS for running up-to date software

  - by rjstelling

  I need to configure a server (*nix) that runs our (bespoke) CMS and Applications. In the bast I have defaulted to using Cent OS 5, but I find this difficult to upgrade the software to the versions we require. For example, we need PHP 5.3, but CentOS 5 has 5.2. Updating is fine but breaks something else (normally MySQL support in PHP). Eventually it will get to a situation where I can't upgrade because of missing dependancies and incompatible versions. Error: Missing Dependency: httpd = 2.2.3-43.el5.centos.3 is needed by package httpd-devel-2.2.3-43.el5.centos.3.i386 (updates) Is there a better alternative OS for hassle free updates, I need: Apache 2.2.17 (the development version for apxs) MySQL 5.5.8 PHP 5.3.5

• Best idea dataserver serving small pictures 40 ko

  - by Nicolas Manzini

  I'm designing the server structure for my application in case things go well. I have one server DB connected to multiple server who process connections. All those with lots of RAM and fast processors. (still looking for a way to use the multithread because now it's dumb apache php... so loooots of ram needed). Upon an answer from those servers, the client can then connect to another server to retrieve pictures using the address he previously got from the db. Is it a good idea to have one database server with let's say nginx and ssd disk having to send all pictures to everybody? or should I have multiple server accessing to a shared ssd disk drive or multiple disk updating each other? Also should I put a lot of RAM on the database server? because probably there wont be a picture more popular than another.

• How should I join these 3 SQL queries in Oracle?

  - by Nazgulled

  I have these 3 queries: SELECT title, year, MovieGenres(m.mid) genres, MovieDirectors(m.mid) directors, MovieWriters(m.mid) writers, synopsis, poster_url FROM movies m WHERE m.mid = 1; SELECT AVG(rating) FROM movie_ratings WHERE mid = 1; SELECT COUNT(rating) FROM movie_ratings WHERE mid = 1; And I need to join them into a single query. I was able to do it like this: SELECT title, year, MovieGenres(m.mid) genres, MovieDirectors(m.mid) directors, MovieWriters(m.mid) writers, synopsis, poster_url, AVG(rating) average, COUNT(rating) count FROM movies m INNER JOIN movie_ratings mr ON m.mid = mr.mid WHERE m.mid = 1 GROUP BY title, year, MovieGenres(m.mid), MovieDirectors(m.mid), MovieWriters(m.mid), synopsis, poster_url; But I don't really like that "huge" GROUP BY, is there a simpler way to do it?

• best way to record local modifications to an application's configuration files

  - by Menelaos Perdikeas

  I often install applications in Linux which don't come in package form but rather one just downloads a tarball, unpacks it, and runs the app out of the exploded folder. To adjust the application to my environment I need to modify the default configuration files, perhaps add an odd script of my own and I would like to have a way to record all these modifications automatically so I can apply them to another environment. Clearly, the modifications can not be reproduced verbatim as things like IP addresses or username need to change from system to system; still an exhaustive record to what was changed and added would be useful. My solution is to use a pattern involving git. Basically after I explode the tarball I do a git init and an initial commit and then I can save to a file the output of git diff and a cat of all files appearing as new in the git status -s. But I am sure there are more efficient ways. ???

• Ubuntu on Oracle VirtualBox: Shared folders

  - by Rosarch

  I looked at this question, but it didn't help. I'm running Windows 7 as a host with Ubuntu 10.10 as a guest with VBox 4.0. I want to have a shared directory between the two. I have installed Guest Additions. I went to the VBox control panel in Windows, added a Shared Folder (sharename Shared_Folder), and chose "Auto Mount". A directory named "sf_Shared_Folder" appeared in /media on Ubuntu, but when I put files in that directory from an OS, I can't see them on the other one. I then tried to create a directory without automounting (sharename collectivefiles), and to run the following command: foo@foo-VirtualBox:~$ sudo mount -t vboxsf collectivefiles FileShare /sbin/mount.vboxsf: mounting failed with the error: No such device What is causing this error? I rebooted both the VM and VBox itself, but I'm still observing this.

  - by mattcodes

  Previous used Ubuntu Gnome with Compiz but for my basic spec intel macbook (4 years old) its a little too heavyweight. So for now Im back on my macbook with os x, but now considering going back to Linux. Im looking for a window manager that has the following properties: 1) Supports virtual desktop (need 4 minimum) 2) Works well with multi monitors - can move an app with shortcut from one monitor to the other (on same virtual desktop) 3) Can remember window position (i.e. open vim on 2 monitor) - however must coerce everything back to first window when 2nd screen is unplugged 4) Keyboard shortcut friendly 5) Not too hard to install 6) Works well with minimum hardware such as integrated graphics Please suggest and share your experiences
