  • Problem with authentication of users via IE when using "host header value"

    - by Richard
    Hi, I'm trying to set multiple web sites up in an IIS 6. I've got a working virtual site residing under the default web site, but if I create a new web site in the IIS and asign it a host header value, let it point to the very same file structure as in the prevoiusly mentioned site and finally asign windows integrated security only to the site - I still cannot log in to the new site using MSIE 6 or 8 but FF 3.5 works fine. In the web log I get these entries if I access the localhost site 2009-11-19 09:15:59 W3SVC1 127.0.0.1 GET /client/ - 80 - 127.0.0.1 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.2;+Trident/4.0;+.NET+CLR+2.0.50727) 401 2 2148074254 2009-11-19 09:15:59 W3SVC1 127.0.0.1 GET /client/ - 80 - 127.0.0.1 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.2;+Trident/4.0;+.NET+CLR+2.0.50727) 401 1 0 2009-11-19 09:15:59 W3SVC1 127.0.0.1 GET /client/Default.asp - 80 xxx\Administrator 127.0.0.1 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.2;+Trident/4.0;+.NET+CLR+2.0.50727) 200 0 0 If I however access via the host headre value site I get prompted to login but the login fail and I also get an error "401 1 2148074252" which not present when it succeeds.

For what reasoon is the IE so stubornly refusing to submit credentials to the "host header value" site? The site is in the Local intranet Zone and login is ticked for that zone. No teaming NIC's no FW, no nothing, I'm cluless :( /Richard

  • Enterprise Tape Backup solutions

    - by Tom O'Connor
    I'm currently attempting to re-architect a backup solution where I'm working. We've got 2 NAS devices, one in the office, one in the datacentre. The servers in the DC back up to the DC NAS, which is then replicated to the Office NAS. The office NAS exports shares as CIFS and NFS, this bit is fine. At some point, I'll have to expand our storage capacity, currently we've got about 1.4TB of storage space, which is about 96% full. Previously, the tape backup was a script that ran tar a few times and squirted data onto a tape. It worked, but was by no means a perfect solution. Restores are a bit of a pest, adding new data to the backup requires editing the script as root. It's just all a bit non-ideal. I've been evaluating a number of "enterprise" ready backup solutions, such as Yosemite Backup from Barracuda, Acronis Backup/Restore, and something from Arkeia. In the process of evaluating these, I've found 2 big problems. Not all of them allow backup of mounted devices (such as a NFS mounted NAS) Many of these applications don't like our tape device. For the most part, (1) is essential. Our NAS has a feeble processor and can't run applications like backup agents. I suspect that the biggest problem is the tape device, which is a HP C7438A DAT72 connected via USB. Questions: Has anyone else got an USB DAT72 device working with similar software? Is there a better way to back up data from an "appliance" NAS device on which you can't run an agent? Would I be totally out of my mind to specify a cheap HP or Dell server with a couple of 1TB hard disks, and a SAS card to then talk to an HP Ultrium (or similar) device? The biggest drawback to this would be cost (400ish for the server, 200 for the SAS connectivity and 1700 for a LTO4 device) Notes: I'd love to be able to say that I'd get rid of tapes entirely, and use some form of hard disk backup. In a previous job, we had LaCie USB drives, which were decidedly unreliable.

  • Looking for a fiber optic "switch" or "router" for home use

    - by Shrout1
    The gist of my question: What is a "fiber optic" switch called? I.E. a layer 2 ethernet switch that uses fiber TX and RX connections and sends layer 2 network traffic between the fiber strands that are connected. Can someone purchase a dedicated fiber switch that does not have copper ethernet ports? What is the current average price of a device like this? Not necessarily looking for product endorsements, just information Might not make sense to go this route if it is too cost prohibitive What type of fiber connector is used for terminating a fiber strand into a jack on the wall? Can fiber be "patched" using two jacks and a "patch" cable? Is signal loss a concern with the longest runs at 100-200ft, a patch cable and media converters? The full story: My parents had unterminated fiber optic cable and terminated Cat5e run throughout their home when it was built in 2004. 10 years later the Cat5e isn't providing the throughput that my father needs to accomplish multiple streams of HD and fast system backups throughout the house. He can't reach gigabit speeds across the distance of the Cat5e runs. We are both interested in terminating the fiber connections and using them as high speed "backbones" to copper switches in each room of the house. It would be easy to attain gigabit speeds (or better, eventually) using the fiber. I have searched and searched for a "fiber optic switch" or "fiber optic router" and cannot find the correct term to describe this piece of hardware. We can use fiber media converters at the end points of each connection, however it would be nice to have a "patch panel" set up in the network closet in the basement that has fiber connections on it and switches the ethernet streams between the connections/systems in the house. Each fiber media converter costs between $50-$100 a piece... After 10 or so terminated connections it might make sense to find a piece of hardware that does not require media converters. That would depend upon the cost of this hardware Somewhat unrelated, if we are able to route between these fiber strands successfully, what is the physical connector type used in a jack on the wall? Just like RJ45 has a wall outlet (depicted below): What is the fiber optic equivalent of this? In the interim could we "patch" a couple fiber strands together in the network closet? Would signal loss be of concern with a run length of 100-200 feet, a patch cable and two media converters? If that would work then it could be used until the funds are available for more.

  • Amusing or Sad? Network Solutions

    - by dbasnett
    When I got sick my email ended up in every drug sellers email list. Some days I get over 200 emails selling everything from Viagra to Xanax. Either they don't know what my condition is or they are telling me you are a goner, might as well chill-ax and have a good time. In order to cut down on the mail being downloaded I thought I would add all of the Junk email senders from Outlook to my Network Solution mail server. Much to my amazement I could not find that import Spammers button, so I submitted a tech support request. Here is the response: Thank you for contacting Network Solutions Customer Service Department. We are committed to creating the best Customer experience possible. One of the first ways we can demonstrate our commitment to this goal is to quickly and efficiently handle your recent request. We apologize for any inconvenience this might have caused you. With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers. An alternative option is for you to create a Custom Filter that filters unwanted e-mails. To create a Custom Filter: Open a Web browser (e.g., Netscape, Microsoft Internet Explorer, etc.). Type mail.[domain name].[ext] in the address line. Login to your Network Solutions email account. Click on the Configuration left menu tab. Click on the Custom Filter link. Type the rule name. blah, blah, blah Basically add them one at a time. "We are committed to creating the best Customer experience possible." No you are not. You are trying to squeeze every nickle you can out of me. "With regard to your concern, please be advised that we cannot import blocked senders in to you e-mail servers." Maybe I should apply for a job to write those ten complicated lines of code... Maybe I should question my choice of vendors, because if they truly "cannot" then they are to stupid to have my business. It is both amusing and sad. I'll be posting this in every forum I am a member of.

  • User given a login prompt when closing Word documents after viewing them in IE7

    - by Martin Owen
    When using IE7 to view Word documents on our CRM system (an ASP.NET 2.0 application running on Windows Server 2003 and IIS 6 and using Windows authenticaton) I'm finding that a prompt appears when the user closes the document. The Word document is originally opened by clicking a link in the CRM system. Are there permissions that I can set on the folder containing the Word documents to prevent this prompt? I've already tried only allowing the Read permission for the Users group (I've left Administrators with Full Control.) If there's another solution to this without using permissions please let me know. UPDATE: I ran Fiddler as suggested by JD and here is the output from the two responses after the request for the document. The first seems to be a DAV response and the second is the authentication request. How do I prevent the DAV response and just return the .doc on the server? OPTIONS / HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 200 OK Date: Thu, 18 Feb 2010 13:37:36 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MS-Author-Via: DAV Content-Length: 0 Accept-Ranges: none DASL: <DAV:sql> DAV: 1, 2 Public: OPTIONS, TRACE, GET, HEAD, DELETE, PUT, POST, COPY, MOVE, MKCOL, PROPFIND, PROPPATCH, LOCK, UNLOCK, SEARCH Allow: OPTIONS, TRACE, GET, HEAD, COPY, PROPFIND, SEARCH, LOCK, UNLOCK Cache-Control: private ------------------------------------------------------------------ OPTIONS /docs/ZONE%20100-105.doc HTTP/1.1 Translate: f User-Agent: Microsoft Data Access Internet Publishing Provider Protocol Discovery Host: <REMOVED> Content-Length: 0 Connection: Keep-Alive Pragma: no-cache X-NovINet: v1.2 HTTP/1.1 401 Unauthorized Content-Length: 83 Content-Type: text/html Server: Microsoft-IIS/6.0 WWW-Authenticate: Basic realm="<REMOVED>" X-Powered-By: ASP.NET Date: Thu, 18 Feb 2010 13:37:36 GMT ------------------------------------------------------------------ UPDATE 2: I found a potential workaround for the problem via this post: http://forums.iis.net/p/1149091/1868317.aspx. I moved all of the documents that are being requested into a folder outside of the web root, and created a virtual directory for it (also outside of the web root). When I followed a link to one of the documents in IE and then closed the document I wasn't presented with a login prompt. I should point out that I'm not using FPSE, unlike the person in the forum post. Ideally I don't want to have to put the documents in a separate virtual directory, but this is the simplest solution I've found so far.

  • Force Finder to log in as Guest to a SMB share

    - by slhck
    I have a QNAP NAS that offers a few SMB shares. As I'm in a trusted environment, my shares are accessible as guest rather than with a combination of username and password. Problem Now, when I click the name of the device in Finder's sidebar, I get the black "Connection failed" bar, with the option "Connect as...". When I click that, I receive: I can however press ? + K and enter the server's name manually, which gets me to this window: Here, I have to select "guest". Now, I can select one of the shares to connect to, and I'm finally connected to the server. If I select it in the sidebar, I get a list of all shares available, because I'm connected as "guest", obviously: What I need Well, as soon as I unmount all shares, I have to go through the same procedure of manually logging in as "guest" again, which I find quite annoying. Is there any way I could get Finder (or the underlying SMB client) to know which credentials to use? Or should I look for the solution rather on the server side? (I know that other SMB shares seem to work fine in my network) Diagnostics The only thing I can get out of Console.app is: 5/15/11 7:36:40 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[200] SharePointBrowser::handleOpenCallBack returned 64 This message occurs when I click the name of the SMB server in the Finder sidebar.

  • Varnish, hide port number

    - by George Reith
    My set up is as follows: OS: CentOS 6.2 running on an OpenVZ virtual machine. Web server: Nginx listening on port 8080 Reverse proxy: Varnish listening on port 80 The problem is that Varnish redirects my requests to port 8080 and this appears in the address bar like so http://mysite.com:8080/directory/, causing relative links on the site to include the port number (8080) in the request and thus bypassing Varnish. The site is powered by WordPress. How do I allow Varnish to use Nginx as the backend on port 8080 without appending the port number to the address? Edit: Varnish is set up like so: I have told the Varnish daemon to listen to port 80 by default. VARNISH_VCL_CONF=/etc/varnish/default.vcl # # # Default address and port to bind to # # Blank address means all IPv4 and IPv6 interfaces, otherwise specify # # a host name, an IPv4 dotted quad, or an IPv6 address in brackets. # VARNISH_LISTEN_ADDRESS= VARNISH_LISTEN_PORT=80 # # # Telnet admin interface listen address and port VARNISH_ADMIN_LISTEN_ADDRESS=127.0.0.1 VARNISH_ADMIN_LISTEN_PORT=6082 # # # Shared secret file for admin interface VARNISH_SECRET_FILE=/etc/varnish/secret # # # The minimum number of worker threads to start VARNISH_MIN_THREADS=1 # # # The Maximum number of worker threads to start VARNISH_MAX_THREADS=1000 # # # Idle timeout for worker threads VARNISH_THREAD_TIMEOUT=120 # # # Cache file location VARNISH_STORAGE_FILE=/var/lib/varnish/varnish_storage.bin # # # Cache file size: in bytes, optionally using k / M / G / T suffix, # # or in percentage of available disk space using the % suffix.

  • Cannot access website from inside network

    - by musclez
    I have a website running from my internal network available at the example IP 192.168.1.5. When I type this in to the browser, it redirects to my domain name ie, "example.com", and gives me Error code: ERR_CONNECTION_REFUSED. Any other machine that is inside of the network can access the website. The website is also accessible outside of the network. Other services from the server, like file sharing or ftp, are available to all machines in the network including the one i'm having issues http issues with. The issue may be linked to a proxy service, but from my understanding the service has been completely disabled and any executable have been uninstalled from the machine. I am wondering if there is some residual proxy information remaining on the machine that limits the connection. I'm fairly positive that "example.com" is what is being blocked by the local machine, and not an IP address being blocked or a faulty connection. When I examine the hosts file, there are no redirects to the local machine for "example.com". There was a rule, as on my other machines within the network: 192.168.1.5 example.com But i have since removed that for troubleshooting purposes. What intrigued me is that when I use the actual IP, the IP address will redirect to the domain in the browser and THEN say ERR_CONNECTION_REFUSED. Server-Side Results The server logs are reporting this: example.com ::1 - - [Date & time] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2. 2.22 (Unix) (internal dummy connection)" However, this seems to be irrelevant as it is not triggered when I try to connect to the server with the specified machine. Fiddler results: Host: *example.com* Proxy-Connection: keep-alive Chrome-Side [Fiddler] The connection to 'example.com' failed. Error: ConnectionRefused (0x274d). System.Net.Sockets. SocketException No connection could be made because the target machine actively refused it 01.23.45.67:80 01.23.45.67:80 would be the external IP, which the server and the machine in question both share. I am doing so reading into 0x274d and its coming back with .NET web.config information. I am still at a loss to what to do with this information. I have WireShark running as well. Theres is a lot of sensitive information in the readout and I'm not sure what to extract from it. Either way, if it helps, I can access that information if anyone would like me to. Thanks for the help!

  • HTTP Content-type header for cached files

    - by Brian
    Hello, Using Apache with mod_rewrite, when I load a .css or .js file and view the HTTP headers, the Content-type is only set correctly the first time I load it - subsequent refreshes are missing Content-type altogether and it's creating some problems for me. Specifically, gzip is not compressing these files. I can get around this by appending a random query string value to the end of each filename, eg. http://www.site.com/script.js?12345 However, I don't want to have to do that, since caching is good and all I want is for the Content-type to be present. I've tried using a RewriteRule to force the type but still didn't solve the problem. Any ideas? Thanks, Brian More Details: HTTP headers WITHOUT random query string value: http://localhost/script.js GET /script.js HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost/ Cookie: PHPSESSID=ke3p35v5qbus24che765p9jni5; If-Modified-Since: Thu, 29 Apr 2010 15:49:56 GMT If-None-Match: "3440e9-119ed-485621404f100" Cache-Control: max-age=0 HTTP/1.1 304 Not Modified Date: Thu, 29 Apr 2010 20:19:44 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 PHP/5.3.1 Connection: Keep-Alive Keep-Alive: timeout=5, max=100 Etag: "3440e9-119ed-485621404f100" Vary: Accept-Encoding X-Pad: avoid browser bug HTTP headers WITH random query string value: http://localhost/script.js?c947344de8278053f6edbb4365550b25 GET /script.js?c947344de8278053f6edbb4365550b25 HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: */* Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://localhost/ Cookie: PHPSESSID=ke3p35v5qbus24che765p9jni5; HTTP/1.1 200 OK Date: Thu, 29 Apr 2010 20:14:40 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 PHP/5.3.1 Last-Modified: Thu, 29 Apr 2010 15:49:56 GMT Etag: "3440e9-119ed-485621404f100" Accept-Ranges: bytes Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 24605 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: application/javascript

  • HAProxy causing delay

    - by user1221444
    I am trying to configure HAProxy to do load balancing for a custom webserver I created. Right now I am noticing an increasing delay with HAProxy as the size of the return message increases. For example, I ran four different tests, here are the results: Response 15kb through HAProxy: Avg. response time: .34 secs Transacation rate: 763 trans/sec Throughput: 11.08 MB/sec Response 2kb through HAProxy: Avg. response time: .08 secs Transaction rate: 1171 trans / sec Throughput: 2.51 MB/sec Response 15kb directly to server: Avg. response time: .11 sec Transaction rate: 1046 trans/sec throughput: 15.20 MB/sec Response 2kb directly to server: Avg. Response time: .05 secs Transaction rate: 1158 trans/sec Throughput: 2.48 MB/sec All transactions are HTTP requests. As you can see, there seems to be a much bigger difference between response times for when the response is bigger, than when it is smaller. I understand there will be a slight delay when using HAProxy. Not sure if it matters, but the test itself was run using siege. And during the test there was only one server behind the HAProxy(the same that was used in the direct to server tests). Here is my haproxy.config file: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 10000 user haproxy group haproxy daemon #debug defaults log global mode http option httplog option dontlognull retries 3 option redispatch option httpclose maxconn 10000 contimeout 10000 clitimeout 50000 srvtimeout 50000 balance roundrobin stats enable stats uri /stats listen lb1 10.1.10.26:80 maxconn 10000 server app1 10.1.10.200:8080 maxconn 5000 I couldn't find much in terms of options in this file that would help my problem. I have heard suggestions that I may have to adjust a few of my sysctl settings. I could not find a lot of information on this however, most documentation is for Linux 2.4 and 2.6 on the sysctl stuff, I am running 3.2(Ubuntu server 12.04), which seems to auto tuning, so I have no clue what I should or shouldn't be changing. Most settings changes I tried had no effect or a negative effect on performance. Just a notice, this is a very preliminary test, and my hope is that at deployment time, my HAProxy will be able to balance 10k-20k requests/sec to many servers, so if anyone could provide information to help me reach that goal, it would be much appreciated. Thank you very much for any information you can provide. And if you need anymore information from me please let me know, I will get you anything I can.

  • Unable to commit file through svn, server sent truncated HTTP response body

    - by Rocket3G
    I have my own VPS, on which I want to run a simple SVN + chiliproject setup. I have re-installed SVN, CHILI and the OS several times, and it always works for a couple of hours/days and then it just stops working. Well, everything works, except I can't upload any files. Committing directories seems to work just fine, but when I try to commit a file it breaks. I have an error log file, which gives me the following text when I try to commit something x.x.x.x - - [19/Oct/2013:00:01:46 +0200] "OPTIONS /project HTTP/1.1" 200 149 x.x.x.x - - [19/Oct/2013:00:01:46 +0200] "PROPFIND /project HTTP/1.1" 207 346 x.x.x.x - - [19/Oct/2013:00:01:46 +0200] "MKACTIVITY /project/!svn/act/c11d45ac-86b6-184a-ac5a-9a1105d64563 HTTP/1.1" 401 345 x.x.x.x - admin [19/Oct/2013:00:01:46 +0200] "MKACTIVITY /project/!svn/act/c11d45ac-86b6-184a-ac5a-9a1105d64563 HTTP/1.1" 201 262 x.x.x.x - - [19/Oct/2013:00:01:46 +0200] "PROPFIND /project HTTP/1.1" 207 236 x.x.x.x - admin [19/Oct/2013:00:01:46 +0200] "CHECKOUT /project/!svn/vcc/default HTTP/1.1" 201 271 x.x.x.x - admin [19/Oct/2013:00:01:46 +0200] "PROPPATCH /project/!svn/wbl/c11d45ac-86b6-184a-ac5a-9a1105d64563/1 HTTP/1.1" 207 267 x.x.x.x - admin [19/Oct/2013:00:01:46 +0200] "CHECKOUT /project/!svn/ver/1 HTTP/1.1" 201 271 x.x.x.x - - [19/Oct/2013:00:01:46 +0200] "HEAD /project/index.html HTTP/1.1" 404 - x.x.x.x - admin [19/Oct/2013:00:01:46 +0200] "PUT /project/!svn/wrk/c11d45ac-86b6-184a-ac5a-9a1105d64563/index.html HTTP/1.1" 201 269 x.x.x.x - admin [19/Oct/2013:00:02:04 +0200] "DELETE /project/!svn/act/c11d45ac-86b6-184a-ac5a-9a1105d64563 HTTP/1.1" 204 - So it seems that it PUTs the file (test.html) correctly, and somehow somewhere something is wrong (file permissions are alright, when I purposely stated that they are wrong, it gave me errors, which is expected, and they were about the file permissions being incorrect. The odd thing is that files won't get added, but directories are fine. I also have enough storage left on my machine. What I should note, perhaps, is that I use Ubuntu 12.04.3 with ruby 1.9.3, mysql 14.14 and I have it set up that Chiliproject handles the authentication and authorization for the project. It works, because I can commit directories and read it all correctly, though I can't upload files. Help would really be appreciated, as I don't know what on earth is going on with this 'truncated http response body'. I tried to read them with wireshark, but it basically gave me the same information. With regards, Ps. I have no clue what the delay between put and delete is, as it's a file of a mere 500 bytes, so it's uploaded in approximately a second. Pps. I copied this question from StackOverflow to this site, as I didn't know the existence of this site and another user suggested that I'd get more answers here, as it's basically a server fault.

  • Apache ProxyPass Missing Images

    - by EpicOfChaos
    I have a apache server that sits in front of my glassfish server. mydomain.com goes directly to my static files on apache, than if you hit the subdomain forum.mydomain.com it goes to the glassfish webapp forum/ at 127.0.0.1:8080/forum/.

  • How to enable caching on Apache / Ubuntu Linux?

    - by Jim Mischel
    I have a large (several megabytes) XML file that's updated rather frequently (every 10 minutes or less) and gets a lot of traffic. I'd like to implement some caching to reduce bandwidth and server load. Looking at the Apache documents, I see a dizzying array of configuration options that involve various combinations of mod_expires, mod_headers, and mod_cache (and variants). I end up running in circles and the results aren't what I expect. I'm comfortable editing the various configuration files if I have some idea what I'm supposed to change. But at the moment I'm poking around in the dark and that's never a comfortable feeling. So, perhaps if I describe what I want, somebody here can take me by the hand and say, "This is what you need to do." Periodically, this file, call it "stuff.xml" is updated and a new version copied to the directory. The external url would be, for example, http://example.com/stuff.xml. Understand, this part works. Whenever I request the file, I get the expected result. But the file is big and I want to save bandwidth, so first I'd like to implement conditional GET semantics with the If-Modified-Since header. How do I do this? I've enabled mod_headers and mod_expired and added the <FilesMatching> section in my httpd.conf as recommended in countless examples I've seen online, but that didn't change the behavior when made a conditional GET request. I always get a status 200 with the entire document. So how the heck do I implement this? That'll cut down on neeless transfers. I'd also like to limit the amount of data transferred. Seeing as this is XML, gzipping it should save me 50% or more. My next step would be to somehow gzip the file and, if it's not too difficult, store it in memory. That'll cut down on per-access data transfer, and also reduce disk transfers. So how do I implement this type of caching? Thanks in advance.

  • ISC DHCP - Force clients to get a new IP address, instead of the being re-issued their previous lease's IP

    - by kce
    We are in the middle of a migration of our DHCP and DNS services from a Debian-based server to a Windows Server 2008 R2 implementation. The Debian server is running isc-dhcpd-V3.1.1. All of workstations are configured to have fixed-addresses between .3 and .40 (the motivation behind that choice is mostly management/political much like here). DHCP leases are given out in the range of .100 to .175. Statically configured servers live in the .200 block and above (which is mostly empty). When we move to the Windows platform, management/political considerations require me to move the IP ranges around again. We would like to keep .1 - .10 reserved for network appliances, switches, and other infrastructure. .200 will remain designated for servers. The addressing space in between should be available to clients and IPs should be dynamically allocated (Edit: instead of automatic as originally mentioned) by the server. My Address Pool on the Windows Server looks like this: 192.168.0.1 192.168.0.254 (Address range for distribution) 192.168.0.1 192.168.0.10 (IP addresses excluded from distribution) 192.168.0.200 192.168.0.254 (IP addresses excluded from distribution) Currently, we have all of our clients still on the .3 - .40 range, and a few machines still active in the .100 - .175 (although there are lots devices that are powered off that still have expired leases with IPs from that range). Since the lease "database" isn't shared between the old and new DHCP server how can I prevent clients from receiving a lease with an IP address that is currently being held by client with a non-expired lease from the old DHCP server? If I just expand the range on the Debian DHCP server to be 192.168.0.10 - 192.168.0.199 is there a way to force clients to not re-use their old IP address when they send their DHCPDISCOVER? Can I make the Windows DHCP server be authoritiative like the ISC implementation? The dhcpd.conf from the Debian server: ddns-update-style none; authoritative; default-lease-time 43200; #12 hours max-lease-time 86400; #24 hours subnet 192.168.0.0 netmask 255.255.255.0 { option routers 192.168.0.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.0.255; range 192.168.0.100 192.168.0.175; } host workstation-1 { hardware ethernet 00:11:22:33:44:55; fixed-address 192.168.0.3; } ... and so on until 192.168.0.40

  • Problems when trying to connect to a router wirelessly

    - by Ruud Lenders
    The situation - At my girlfriend's parents' place there are six Windows 7 devices that are wired or wireless connected to a router: 3 dekstops and 3 laptops. There are also several smartphones using the router. The router is secured with WPA2 (AES). The problem - We never had any problems with the router for over a year. But recently - about 3 weeks ago - my girlfriend's laptop (HP) and my laptop (ASUS) started to develop problems while trying to connect to the router. The router has stopped showing up from the network list. Sometimes it comes back and shows up, but then it keeps saying something along the lines of "Could not connect", and not long after that it dissapears again. The range of the router is not the problem here, because we experience the same when we sit next to the router. Sometimes, if we are lucky, and waited a long time (10-15 minutes) without using the laptop for anything, the laptop will eventually succesful connect to the router. The attempts - Of course, the Window 7 troubleshooter. We tried troubleshooting the connection problems and the wireless network adapter, but no luck. We also reset the router enough times to know that's not helping either. Here's the full list of things we tried, but did not help: Running the Windows 7 troubleshooter Resetting the router (more than once) Setting the router settings to factory defaults Disconnecting all other devices except one laptop Applying a system restore Trying static/dynamic IP/DNS - Dynamic is better, right? Enabling/disabling IPv6 - Should I keep IPv6 disabled? Running the command: netsh wlan stop hostednetwork Running the command: netsh wlan set hostednetwork mode=disallow Updating/reïnstalling wireless adapter drivers The tests - To help finding the core of the problem, we tested the following: Plugging an ethernet cable in the router and in our laptops - worked fine Connecting someone else's laptop to the router (wireless) - worked fine Connecting our laptops to someone else's router - worked fine The router - This information might be relevant: Router model: Sitecom 300N Wireless Router Router hardware: version 01 The DCHP Server's IPs range from 192.168.0.100 to 192.168.0.200. Router settings: Wireless channel: 12 Channel bandwidth: 20/40 MHz Extension channel: 8 Preamble type: Long 802.11g protection: Disabled UPnP: Enabled The laptops - If you are wondering about our laptops: My laptop model: ASUS Pro64JQ Girlfriend's laptop: HP Pavillion G6 OS: Both Windows 7 Professional x64 - with Service Pack 1 My wireless adapter: Atheros AR9285 AdHoc 11n: Enabled The question - Does anyone have experienced the same problems as I do? Or does someone know how to solve this? Are there more tricks I can try, or settings I should change? Note - Our laptops are not slow or old. My laptop is 1.5 years old, and the other laptop is just 5 months old. I know how to keep laptops clean and I'm pretty sure both laptops are not bloated with useless software.

  • ASA and cisco vs NSA sonic firewall

    - by Lbaker101
    Currently I’m trying to structure our network to fully support and be redundant with BGP/Multi homing. Our current company size is 40 employees but the major part of that is our Development department. We are a software company and continued connection to the internet is a requirement as 90% of work stops when the net goes down. The only thing hosted on site (that needs to remain up) is our exchange server. Right now i'm faced with 2 different directions and was wondering if I could get your opinions on this. We will have 2 ISPs that are both 20meg up/down and dedicated fiber (so 40megs combined). This is handed off as an Ethernet cable into our server room. ISP#1 first digital ISP#2 CenturyLink we currently have 2x ASA5505s but the 2nd one is not in use. It was there to be a failover and it just needs the security+ license to be matched with the primary device. But this depends on the network structure. I have been looking into the hardware that would be required to be fully redundant and I found that we will either of the following. 2x Cisco 2921+ series routers with failover licenses. They will go in front of the ASAs and either connects in a failover state or 1 ISP into each of the 2921 series routers and then 1 line into each of the ASAs (thus all 4 hardware components will be used actively). So 2x Cisco 2921+ series routers 2x Cisco ASA5505 firewalls The other route 2x SonicWalls NSA2400MX series. 1 primary and the secondary will be in a failover state. This will remove the ASAs from the network and be about 2k cheaper than the cisco route. This also brings down the points of failure because it’s just the 2x sonicwalls It will also allow us to scale all the way up to 200-400 users (depending on their configuration). This also makes so the Sonic walls. So the real question is with the added functionality ect of the sonicwall is there a point in paying so much more to stay the cisco route? Thanks!

  • How do I configure a site in IIS 7 for SSL with a wildcard certificate?

    - by michielvoo
    We have an Windows 2008 server with IIS 7 to test sites we develop for our clients. Each site has a binding on a subdomain: clienta.example.com clientb.example.com clientc.example.com (* Using example.com to protect the innocent) For one of these sites we now have to test if it works over https. So I have created a wildcard certificate request with *.example.com as the common name. I have received the certificate (issued by PositiveSSL SA) and completed the request. The certificate is now installed in IIS. Now I have added an https binding to the second site with the following settings: type: https IP address: All Unassigned Port: 443 Host name: clientb.example.com SSL certificate: *.example.com Browsing the site over regular http works fine. When I try to browse the site over https I get the following errors (depending on the browser used): Chrome This webpage is not available Error 102 (net::ERR_CONNECTION_REFUSED): Unknown error. Firefox Unable to connect Firefox can't establish a connection to the server at clientb.example.com Firebug says Status: Aborted Internet Explorer Internet Explorer cannot display the webpage I have checked Failed Request Tracing, and according to the log the request was completed with status 200. I have run the SSL Diagnostics Tool with the following result: System time: Fri, 04 Mar 2011 14:04:35 GMT Connecting to 192.168.2.95:443 Connected Handshake: 115 bytes sent Handshake: 3877 bytes received Handshake: 326 bytes sent Handshake: 59 bytes received Handshake succeeded Verifying server certificate, it might take a while...

  • How do I permanently delete e-mail messages in the sendmail queue and keep them from coming back?

    - by Steven Oxley
    I have a pretty annoying problem here. I have been testing an application and have created some test e-mails to bogus e-mail addresses (not to mention that my server isn't really set up to send e-mail anyway). Of course, sendmail is not able to send these messages and they have been getting stuck in the sendmail queue. I want to manually delete the messages that have been building up in the queue instead of waiting the 5 days that sendmail usually takes to stop retrying. I am using Ubuntu 10.04 and /var/spool/mqueue/ is the directory in which every how-to I have read says the e-mails that are queued up are kept. When I delete the files in this directory, sendmail stops trying to process the e-mails until what appears to be a cron script runs and re-populates this directory with the messages I don't want sent. Here are some lines from my syslog: Jun 2 17:35:19 sajo-laptop sm-mta[9367]: o530SlbK009365: to=, ctladdr= (33/33), delay=00:06:27, xdelay=00:06:22, mailer=esmtp, pri=120418, relay=e.mx.mail.yahoo.com.

As a side note, I'd also like to know if there is a way to set up sendmail to "fake" sending e-mail. Is there?

  • What presentation software suits my needs?

    - by claws
    Background: I'm teaching biology to 12th grade students. The syllabus I'm teaching is huge. I mean literally, very huge. There is a lot for students to remember. There are no less than 1000 facts (weird names, dates etc) for students to remember. They'll have to remember all of them, they don't have a choice. The notes I compiled for their learning itself is upto 80 printed pages(Just the bullet outline & facts). That's just one chapter. We have 34 chapters. Also my students are very hardworking, they study upto 8-10hrs per day (Yeah! we are from India :). So, I want to ensure maximum retaining by the students at each and every stage (Teaching & Learning). I'm trying to as many memory training techniques as possible. I'm trying to incorporate, mnemonics, strong visual aids (pictures, 3D-animations, real videos etc.), spaced repetition etc. I think MS powerpoint is not suitable for my needs: There are about 200 slides per chapter. Its very easy for students to get lost while teaching. Because the problem with powerpoint is that it gives facts (as bullets) but it doesn't exploit the association & organization (Concept Map) of the content, which helps students learn quickly. I found an amazing software called XMind. You can see the screenshot here. Problem is that it is not as powerpoint in terms of powerpoint. This software can be used for just for concept maps. In the above screenshot, each topic occupies a single slide. I have an Image/picture(Detailed huge picture) and about 5-10 bullet points and probably a video or an animation of somethings. And this XMind is not good at presenting, in terms that it doesn't allow me to set what to present after what. I want to present a top down view, with a slide for each topic. PS: I Don't like prezi.com. I tried but it simply is too confusing for my students. It zooms here and there. I didn't tried it but I've seen few presentations.

  • Lag spikes at full CPU usage, maybe video card

    - by Roberts
    I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

  • Backing up data stored on Amazon S3

    - by Fiver
    I have an EC2 instance running a web server that stores users' uploaded files to S3. The files are written once and never change, but are retrieved occasionally by the users. We will likely accumulate somewhere around 200-500GB of data per year. We would like to ensure this data is safe, particularly from accidental deletions and would like to be able to restore files that were deleted regardless of the reason. I have read about the versioning feature for S3 buckets, but I cannot seem to find if recovery is possible for files with no modification history. See the AWS docs here on versioning: http://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectVersioning.html In those examples, they don't show the scenario where data is uploaded, but never modified, and then deleted. Are files deleted in this scenario recoverable? Then, we thought we may just backup the S3 files to Glacier using object lifecycle management: http://docs.aws.amazon.com/AmazonS3/latest/dev/object-lifecycle-mgmt.html But, it seems this will not work for us, as the file object is not copied to Glacier but moved to Glacier (more accurately it seems it is an object attribute that is changed, but anyway...). So it seems there is no direct way to backup S3 data, and transferring the data from S3 to local servers may be time-consuming and may incur significant transfer costs over time. Finally, we thought we would create a new bucket every month to serve as a monthly full backup, and copy the original bucket's data to the new one on Day 1. Then using something like duplicity (http://duplicity.nongnu.org/) we would synchronize the backup bucket every night. At the end of the month we would put the backup bucket's contents in Glacier storage, and create a new backup bucket using a new, current copy of the original bucket...and repeat this process. This seems like it would work and minimize the storage / transfer costs, but I'm not sure if duplicity allows bucket-to-bucket transfers directly without bringing data down to the controlling client first. So, I guess there are a couple questions here. First, does S3 versioning allow recovery of files that were never modified? Is there some way to "copy" files from S3 to Glacier that I have missed? Can duplicity or any other tool transfer files between S3 buckets directly to avoid transfer costs? Finally, am I way off the mark in my approach to backing up S3 data? Thanks in advance for any insight you could provide!

  • What is good usage scenario for Rackspace Cloud Files CDN (powered by AKAMAI) [closed]

    - by Andrew Smith
    I have just setup my website as static page via Rackspace CDN / Akamai. www.example.co.uk is an alias for d9771e6f24423091aebc-345678991111238fabcdef6114258d0e1.r61.cf3.rackcdn.com. d9771e6f24423091aebc-345678991111238fabcdef6114258d0e1.r61.cf3.rackcdn.com is an alias for a61.rackcdn.com. a61.rackcdn.com is an alias for a61.rackcdn.com.mdc.edgesuite.net. a61.rackcdn.com.mdc.edgesuite.net is an alias for a63.dscg10.akamai.net. a63.dscg10.akamai.net has address 63.166.98.41 a63.dscg10.akamai.net has address 63.166.98.40 a63.dscg10.akamai.net has IPv6 address 2001:428:4c02::cda8:ecb9 a63.dscg10.akamai.net has IPv6 address 2001:428:4c02::cda8:ed09 The HTTP header: HTTP/1.0 200 OK Last-Modified: Fri, 19 Oct 2012 23:27:41 GMT ETag: fdf9e14b77def799e09e8ce815a521da X-Timestamp: 1350689261.23382 Content-Type: text/html X-Trans-Id: tx457979be3bd746c2b4e5403a1189cdbc Cache-Control: public, max-age=900 Expires: Sat, 27 Oct 2012 22:18:56 GMT Date: Sat, 27 Oct 2012 22:03:56 GMT Content-Length: 7124 Connection: keep-alive I am wondering, if it's really the fastest solution to power the website? By investigating it thru http://www.just-ping.com/ it seems, that from many places the ping is very high, and during quick investigation I found that they use GeoIP to resolve addresses based on WHOIS, which is not accurate and because of that from many places the ping is above 300ms (for example, if ISP is in balgladore and request is routed to bangladore even if it's 300ms, for period of 1 month), while by just using Amazon Web Services and Route 53 Anycast DNS servers and only 4 EC2 instances it seems that for example India is always below 100ms, while using Akamai it goes above 300ms in some cases, and this is because Route 53 is using BGP. By quickly checking the Akamai, it seems that they are not getting feedback from the traffic - the high ping stays constant even if I keep downloading large files and videos, which is opposite to what they say on their website. They state, that they optimize the performance by taking feedback from the requests, while it seems they just use GeoIP with per City resolution (which are mostly big cities). Because of this, AWS with Route 53 / Anycast DNS seems to be much more reliable, as well EdgeCast which is using BGP, but I dont know how much does it cost to deploy static website. Actually, I dont know if EdgeCast is not a lie, because from isolated places there are many errors - so their performance is at the cost of quality of delivery, because of BGP switching the routes during transfer of large files. So I was wondering, what is really Akamai good for, because they dont seem to pose any strength in any field in what I do understand now, except they offer some software based WAF on their website, but what I really care about is the core distribiution, so the question is? Is really Akamai good for Videos? For static websites? ??? I found so far AWS most usable with most consistent ping and stable transfers.
