  • Blocking a specific URL by IP (a URL create by mod-rewrite)

    - by Alex
    We need to block a specific URL for anyone not on a local IP (anyone without a 192.168.. address) We however cannot use apache's <Directory /var/www/foo/bar> Order allow,deny Allow from 192.168 </Directory> <Files /var/www/foo/bar> Order allow,deny Allow from 192.168 <Files> Because these would block specific files or directories, we need to block a specific URL which is created by mod-rewrite and the page is dynamically created using PHP. Any ideas would be greatly appreciated

  • I have a perl script that is supposed to run indefinitely. It's being killed... how do I determine who or what kills it?

    - by John O
    I run the perl script in screen (I can log in and check debug output). Nothing in the logic of the script should be capable of killing it quite this dead. I'm one of only two people with access to the server, and the other guy swears that it isn't him (and we both have quite a bit of money riding on it continuing to run without a hitch). I have no reason to believe that some hacker has managed to get a shell or anything like that. I have very little reason to suspect the admins of the host operation (bandwidth/cpu-wise, this script is pretty lightweight). Screen continues to run, but at the end of the output of the perl script I see "Killed" and it has dropped back to a prompt. How do I go about testing what is whacking the damn thing? I've checked crontab, nothing in there that would kill random/non-random processes. Nothing in any of the log files gives any hint. It will run from 2 to 8 hours, it would seem (and on my mac at home, it will run well over 24 hours without a problem). The server is running Ubuntu version something or other, I can look that up if it matters.

  • VirtualBox cannot start a virtual machine on Windows 7

    - by Zan Lynx
    Note that this question is mostly so others can find this information. I ran into a problem recently with my Fedora-14 virtual machine running on a Windows-7 host with VirtualBox. VirtualBox could not start the Fedora virtual machine, but it could start a Ubuntu virtual server machine that was configured for 512 MB of RAM. The Fedora-14 machine was configured for 2 GB of RAM. The Fedora-14 machine had been working a week ago. What had I recently changed...? Answer to follow.

  • Barring connections if VPN is down.

    - by Majid
    I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

  • Tools to manage sql 2008 database mirroring?

    - by lemkepf
    We are going to be moving about 20 databases that live on a single instance of sql 2000 to a sql 2008 r2 environment with database mirroring. What I'm looking for is a tool or scripts that will help me manage the conversion and management of those 20db's onto this new mirrored environment easily. There are many steps in setting each DB up and I want to automate as much as possible. Edit: Here are the steps I've been doing manually: Create the same username/passwords from the old sql 2000 server onto new sql 2008 server. Then sync those users/passwords onto the other sql 2008 server with the same SSID's so when we do the db backup and restore they match up. Take a backup of each sql 2000 db's. Copy them to server A. Restore the backup to server A. Backup from server a, copy to server b, restore there. Run the mirror "configure security" wizard. Start mirroring. I've love to be able to script this out or have a tool that does it for me. Thanks! Paul

  • Setting nagios location in map

    - by Mech Software
    I have Nagios installed and I'm working on getting the network map correct. The problem I have is that "Nagios" appears to be in the "internet" when it should be located on the MechNAS server. What I want is Nagios Process to show up inside the local network. So it should show up at the same layer as MechNAS and development. Where exactly is that configured? I didnt see any place to set that up and it looks now like it's out there on it's own. Documentation and Googling didnt seem to turn up anything either.

  • Windows 7, network shares, and authentication via local group instead of local user

    - by Donovan
    I have been doing some troubleshooting of my home network lately and have come to an odd conclusion that I was hoping to get some clarification on. I'm used to managing share permissions in a domain environment via groups instead of individual user accounts. I have a box at home running windows 7 ultimate and I decided to share some directories on that machine. I set it up to disallow guest access and require specifically granted permissions. (password moe?). Anyway, after a whole bunch of time i figured out that even though the shares I created were allowed via a local group i could not access them until i gave specific allowance to the intended user. I just didn't think i would have to do that. So here is the breakdown. Network is windows workgroup, not homegroup or nt domain PC_1 - win 7 ultimate - sharing in classic mode - user BOB - groups Admins PC_2 - win 7 starter - client - user BOB - groups admins PC_3 - win xp pro - client - user BOB - groups admins the share on PC_1 granted permission to only the local group administrators. local user BOB on PC_1 was a member of administrators. Both PC_2 and PC_3 could not browse the intended share on PC_1 because they were denied access. Also, no challenge was presented. They were simply denied. After adding BOB specifically to the intended share everything works just fine. Remember, its not an nt domain just a workgroup. But still, shouldn't i be able to manage share permissions via groups instead of individual user accounts? D.

  • Overcoming maximum file path length restrictions in Windows

    - by Christopher Edwards
    One of our customers habitually use very long path names (several nested folders, with long names) and we routinely encounter "user education issues" in order to shorten the path to less than 260 characters. Is there a technical solution available, can we flick some sort of switch in Windows 7 and Windows 2008 R2 to say "yeah just ignore these historical problems, and make +260 character path name work". P.S. I have read and been totally unedified by Naming Files, Paths, and Namespaces

  • Disk names in Solaris 10 for ZFS: SAS WWN instead of c0t0d0

    - by notpeter
    I currently have a server running Solaris 10u9 with a SAS enclosure (Dell PowerVault MD1000) filled with SATA disks attached to an SAS card (LSI 3801E). It happily recognizes the 15 disks in the MD1000 and presents them each disk in the traditional solaris form (c1t12d0, c1t13d0, c1t15d0, etc). My home ZFS setup (Nexenta CP3 + LSI 9200-16E + directly cabled SATA disks) presents disks as their SAS WWN ID (ex: c3t600039300001EA56d0). Although this ID is longer, I've found it much easier to troubleshoot because the cabling/slot is irrelevant, ZFS just identifies the disk by ID, if it's connected it finds it. Most manufacturers print the WWN right on the disk's top label, can't get much easier than that. So how can I get Solaris to identify disks by SAS WWN instead of by the cXtXdX?

  • Terminal Server Logging Software

    - by Jacob
    I have recently been trying to find software to monitor users' activities on our terminal server. After a quick search, I found http://www.softactivity.com/tsm.aspx. Has anyone ever heard of or used this program? I just want to make sure this company is legit and the software runs efficiently. The server I would be installing it on has about 40-50 users on it. I am hoping the software has some type of setting to only monitor certain users, because i would hate to waste resources. If this is not good software, does anyone have any recommendations?

  • How can I get DVDs playing after a Vista to XP change? [closed]

    - by Liath
    I replaced my vista install on a Dell Inspiron 1525 with XP and have managed to get most things up and running again however I'm having trouble with playing DVDs. When I try and play a DVD I get the following message: Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card. I have ensured that my drive is configured to play Region 2 discs (I'm in the UK), I've installed the most up to date XP codec pack which makes me think it's a driver issue. In device manager I have got my DVD drivers up to date however under "Other Devices" I'm missing several which sound key: Audio Device on High Definition Audio Bus Modem Device on High Definition Audio Bus Video Controller Video Controller (VGA Compatible) However I've installed all the relevant drivers I can find on the Dell website. The drive itself is working - I've run software from the drive. I'm afraid I am far from a sys-admin so I'm struggling on this one. How can I get my DVDs playing again?

  • Apache: How to enable Directory Index browsing at the Doc Root level?

    - by Brian Lacy
    I have several web development projects running on Fedora 13. I generally setup Apache to serve my larger projects as Virtual Hosts, but I've got several small projects cycling through that I don't really care to setup a VirtualHost for each one. Instead I'd like them all under a subdirectory of the main VirtualHost entry. I just want Apache to serve me the directory index when I browse to the host name. For example, the hostname projects.mydomain.com refers to /var/www/projects, and that directory contains only subdirectories (no index file). Unfortunately when I browse to the host directly I get: Forbidden You don't have permission to access / on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. But my virtual host entry in my apache config looks like this: <VirtualHost *> ServerName projects.mydomain.com DocumentRoot /var/www/projects <Directory "/var/www/projects"> Options +FollowSymlinks +Indexes AllowOverride all </Directory> </VirtualHost> What am I missing here?

  • Plesk 9 - Client panel access via client domain, not server host name

    - by Ben
    I've setup a Plesk 9 vps recently. The plesk admin is accessible at, say, http://superawesomedomain.com:8443. I'm setting up a couple of client domains on the server. I'd like clients to be able to access plesk via a similar url, but instead it would be something like http://inferiorclientdomain.com:8443. This works ok in a sense, but it always redirect the request for inferiorclientdomain.com:8443 to superawesomedomain.com:8443. I'd like the control panel access url to remain on inferiorclientdomain.com. Is that possible? EDIT: System Info. Plesk 9.5.2 on CentOS 5 (Build 95100504.12)

  • Script to mirror MS SQL Server databases between 2 servers

    - by David W
    Hi I have about 200 sites each of which have 2 servers running MSSQL (2k5 at some sites, 2k8 at others) One server is production and the other is primarily there as a backup. We're rebuilding all of these servers this year and as part of that we will have to set up mirroring for ... a lot ... of databases. Some of these sites have 45 databases so mirroring them manually is going to be a huge pain. I was going to write a batch script which uses SQLCMD to backup the database and log, copies to the secondary server, restores the backup and log with norecovery, creates the endpoints and sets the partner. This in itself isn't too complicated, but i'd love to see what other people have done as i'm not very confident in catching errors using the process i've outlined above. I've seen Tools to manage sql 2008 database mirroring? Which looks really good, but the formatting is jumbled and I can't get it to work. If anyone has any other scripts they've written and are willing to share I'd be eternally grateful. Ideally I'd love to be able to use a script to ensure there are matching endpoints (same ports) on both servers, backup the database, backup the log, copy the backups to second server, restore database and log with norecovery, set the partners on both servers, and somehow confirm that the databases are linked and synchronized. Well, thanks for reading :)

  • On linux, what does it mean when a directory has size 0 instead of 4096?

    - by kdt
    Here's a strange thing I haven't seen before -- a directory whose size is reported by ls as 0 instead of 4096, and I can't create any files within it. # ls -ld lib home drwxr-xr-x. 2 root root 0 Feb 7 03:10 home <-- it has zero size dr-xr-xr-x. 11 root root 4096 Feb 4 09:28 lib # touch home/foo touch: cannot touch `home/foo': No such file or directory <-- and I can't create files in it # rm home rm: cannot remove `home': Is a directory <-- look, it really is a dir So what does it mean for a directory to have size 0 instead of 4096? Filesystem is ext4 on fedora core 14. The output of mount is: /dev/mapper/vg_dev-lv_root on / type ext4 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0") /dev/vda1 on /boot type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) Output of du -s /home: 0 /home Output of stat /home: File: `/home' Size: 0 Blocks: 0 IO Block: 1024 directory Device: 15h/21d Inode: 34913 Links: 2 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2011-02-07 03:45:46.188995765 -0800 Modify: 2011-02-07 03:11:59.980995019 -0800 Change: 2011-02-06 07:58:45.874995002 -0800

  • How to use a local Leopard Server Mail server acting "like" an Exchange mail server

    - by Richard Chevre
    We have a local Exchange 2003 server (company .local) who is collecting POP3 mail accounts on a distant (company .com) mailserver. The mails are collected by the Exchange server every 5-10 minutes and stored locally (on company .local), so the users can read them without going on the "real" mail server (company.com) What was explaned to me is that the mail collection is made with POP Now we are migrating on Snow Leopard Server. We have chosen to use a new extension for our local domain: .leo So our mailserver's FQDN is mail.company.leo, and the users have a user [email protected] formated mail address. A) All works fine except that I can't find how to tell the mail.company.leo that he must retreive the mails from the "real" public server (mail.company.com) I'm hoping to use IMAP and not POP. I can send mail using SMTP relay from mail.company.leo but (I know it's trivial) answering is not possible, even if I specify the reply-to as [email protected] (this seems to be related to A) ) I don't know if it's very complicated (I suspect not, but...) to achieve what I want to do, and I'm not a genius. But as I'm a little bit lost, I hopesomebody can or will help me. Solving this will allow us to use iCal invitations too, so a lot of services depends of these mailserver settings Some of you discuss the fact thta we choose to use a "new" tld with the .leo extension. We have no problem for that, we could use .local. no problem ;) We used .leo instead of .local just to differentiate the two systems (Exchange and SnowLeopardServer). The question was not about that, it was just to know if we can set a SnowLeopard mail server to act like an Exchange Server. Again thank you for your advice and help Richard Thanks in advance Richard

  • Redirect from folder containing website

    - by Sam
    I have a website reached from this url: http://www.mysite.com/cms/index.php being served from this directory: public_html/cms/index.php In public_html I have this .htaccess RewriteRule (.*) cms/$1 [L] Which lets me get to the site like this: http://www.mysite.com/index.php But now if I reference the 'old' address, I'd like to redirect to the rewritten address with a permanent redirect code. for example: http://www.mysite.com/cms/?q=node/1 is redirected to... http://www.mysite.com/?q=node/1 How can I make this happen? EDIT: Also in the .htaccess file supplied with Drupal(cms), this is written. I've tried enabling it, but it doesn't seem to have any effect. # Modify the RewriteBase if you are using Drupal in a subdirectory or in a # VirtualDocumentRoot and the rewrite rules are not working properly. # For example if your site is at http://example.com/drupal uncomment and # modify the following line: # RewriteBase /drupal EDIT: Including more of my .htaccess file - seems relevant. # Block access to "hidden" directories whose names begin with a period. RewriteRule "(^|/)\." - [F] #Strip cms folder from url RewriteRule (.*) cms/$1 RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^ index.php [L] # Rules to correctly serve gzip compressed CSS and JS files. # Requires both mod_rewrite and mod_headers to be enabled. <IfModule mod_headers.c> # Serve gzip compressed CSS files if they exist and the client accepts gzip. RewriteCond %{HTTP:Accept-encoding} gzip RewriteCond %{REQUEST_FILENAME}\.gz -s RewriteRule ^(.*)\.css $1\.css\.gz [QSA] # Serve gzip compressed JS files if they exist and the client accepts gzip. RewriteCond %{HTTP:Accept-encoding} gzip RewriteCond %{REQUEST_FILENAME}\.gz -s RewriteRule ^(.*)\.js $1\.js\.gz [QSA] # Serve correct content types, and prevent mod_deflate double gzip. RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1] RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1] <FilesMatch "(\.js\.gz|\.css\.gz)$"> # Serve correct encoding type. Header append Content-Encoding gzip # Force proxies to cache gzipped & non-gzipped css/js files separately. Header append Vary Accept-Encoding </FilesMatch>

  • How to enable 'playback follows cursor' / 'skip silence' in itunes?

    - by xor_eq
    foobar has got two pretty simple, yet very useful features (at least for me) that iTunes seems to be lacking: Playback follows cursor - Playback continues at the selected track Skip silence - Those 25 minute songs, containing 20 minutes of silence and then some final brainfart that's called "hidden track"... this feature just skips the silence, plays the final bit and continues with the next song Is it possible somehow to enable those features in iTunes?

  • Will you install software on the same partition as Windows system?

    - by Tim
    I was wondering if you always install software on the same partition as Windows 7 system? What kinds of software do you install on the same partition as Windows system? What kinds of software you install on another partition? If you install software on another partition, do you install them on a dedicated partition to these software? Or do you install them on the same partition as data (personal data)? How do you plan the sizes for the partition(s) in either case? What are to consider when making plans about the above questions? The software I am installing include: Matlab, Mathematica, IDEs, compilers or Interpreters for C++, C, Java, R, Python, Perl, Lisp, Latex, and database. Mainly for programming and typesetting kinds of studies and projects.

  • How to add tags to emails in Gmail

    I want a way to tag emails in Gmail so that I can remember their sources and context. I'm not talking about labels, imagine this scenario; I sent an email to more than 8 recipients, and then they answered me, each recipient is teaching a different course, and I want to tag each received email with its specific course. All the emails are under one label as you see in the following picture: Is there any way to tag email in Gmail, the same way we can tag posts on Google reader? Thank you

  • Firefox Wordwrap

    - by AtlantaBill
    The text displayed in several, forum sites that I frequently visit does not automatically word wrap in Firefox's window. Rather, it just "runs off" the right end of the window. I can cause the text to properly word-wrap by maximizing the window and then immediately returning it to its normal size. This lasts until I move to another page and then I have to repeat this "work-around" to display word-wrapped text properly again. Anyone have any ideas on what I can do to make Firefox always automatically word-wrap text? TIA. Bill

  • Pin the Dock to the top

    - by Chris Buchholz
    I wonder if it is possible to pin the Mac OS X Dock to the top in Snow Leopard? I see lets of ideas on how to do this when I google for it, and Secrets (the tweaking app) also provide it as an option, but I don't see any of the ways working for me. I guess it must have worked at some point, since people said it did, but I believe this feature might have been removed from Snow Leopard, and therefore does not work for me. Is this so? Is there really no way to pin the Dock to the top of screen? If not, what ways of "getting rid of the dock" can you guys recommend? I have tried with auto-hiding, but my problem is that this will leave a 4px line at the edge of where the Dock is pinned to, that applications wont cover. Thats not ideal for me. As far as I have understood from googling, this line will not appear if the Dock is pinned to the top, hence my question. What other ways do you guys use to get rid of it?
