  • Why is this static routing not working ?

    - by geeko
    Greeting gurus, I'm trying to develop a DHCP enforcement extension like Microsoft NAP. My trick to block dynamic-IP requesting machines (that don't meet certain policy) is to strip the default gateway (no default gateway) stated in the IP lease and set the lease subnet mask to 255.255.255.255. Now I need the blocked machines to be able to reach some specific locations (IPs) on the network. To allow for this, I'm including some static routes in the lease. For example, I'm including 10.10.10.11 via router 10.10.10.254 (the one to which the blocked machine that needs to access 10.10.10.11 is connected). Unfortunately, as soon as I set the default gateway to nothing, blocked machines cannot reach any of the added static routes. I also tried classless static routes. Any ideas ? any one knows how MS NAP actually do it ? Geeko

  • Why is it a bad idea to use multiple NAT layers or is it?

    - by iamrohitbanga
    The computer network of an organization has a NAT with 192.168/16 IP address range. There is a department with a server that has an IP address 192.168.x.y and this server handles hosts of this department with another NAT with the IP address range 172.16/16. Thus there are 2 layers of NAT. Why don't they have subnetting instead. This would allow easy routing. I feel multiple layers of NAT can cause performance losses. Could you please help me compare the two design strategies.

  • Smart subdomain routing via reverse proxy

    - by Trevor Hartman
    I have two servers on my home network: OSX Server and an Ubuntu Server. I'd love to have external subdomains osx.mydomain.com point to osx and ubuntu.mydomain.com point to ubuntu. I know the normal way to do this is to have a static external IP address for each, but that's not an option as this is just my home setup. My question is: is there a way to do this with some reverse proxy trickery? OSX is currently the default entry point for all traffic. I was able to setup a reverse proxy on OSX for ubuntu.mydomain.com on port 80, so web traffic was correctly being proxied to my ubuntu. I'd like to ssh and do a bunch of other stuff though!

  • Can I grant permissions on files in windows 7 using a security identifier from another machine

    - by Thomas
    I have an external hard drive, and I wish to grant permissions on some files to users from 2 different computers without having to hook it up to the 2 different computers. I know the SID of the user on the other computer, I'd like to know if and how I can grant permissions to files using the SID. I'm running Windows 7 Professional 64 bits, and "The Other" computer Win 7 Home Premium 64 bits, they are not in a domain, but separate computers on a home network (not even same homegroup). Note: Duplicated question with: Is there a way to give NTFS file permissions to users from other Windows installations?

  • Suggest Wireless AP

    - by sunny
    I'm doing a data and voice install for a client in the hotel industry. I'm done with voice and am looking for my options to provide a Wireless AP. The building's dimensions are 100ft X 50ft. There are a ton of options out there which have left me confused now. Please help me decide. I am not clear as to how I should ensure that the Wireless Network is visible throughout the premises. Personally I would love to setup a WDS on 3-4 linksys wrt54gl routers using OpenWRT. Is this advisable? If not please recommend some other AP's. If a more expensive appliance is absolutely necessary, then please suggest something that can be powered using IEEE 802.3af PoE. Thanks

  • Going on 15 months for me...

    - by Ratman21
    About 5 face to face interviews, 4 telephone ones and except for the two weeks Census Job. But, after 15 months looking for work, I am still with out a JOB. What is wrong here or with me? Let’s see, hard worker (check), self motivated to do well on a Job (Check), Certified CompTIA A+, Security+  and Network+ Technician (Check), 20 + years experience in “IT” (CHECK), in good health, in 20 years of work only 15 days off due to health issues (Check), 18 years experience as technical Help Desk support (Check), can still work better than younger personal (Check), Strong trouble shooting skills for software, computer hard ware and circuit issues (Check) and Multiple software languages (Hey I have done some programming) Check. Hmm I don’t see any problem with me (of course I could have missed something, please let me know if you see what I am missing).    Now as to what have I been up to since I last blogged. The same things of course, Job hunting, job hunting and study.   I have set up sim of my home LAN and will be adding a wireless print server to the sim and in real life, soon.  I was able to pull up and copy the examples of Cisco router commands that I had on my old lap top, to my newer PC. Every time I used a new command while working the NOC on my last job.   I would cut and past a copy of the command on the router (and what it did) I was working on.  Along with notes on the problem and commands use for same router. I used these to make documentation for on how to handle these types of issues, for the other Operation Techs. My old notes are helping me in studying for the CCENT test.    As to Love Dare, I think it will take more like 40 weeks, than the 40 days of the book. Yes I am making progress, slow but, it is progress. I will have more on that in my next blog.

  • How can I create profiles for the windows that are open on my Mac?

    - by Kyle Hayes
    As a semi-dual monitor user on my MacBook, I run into a particular issue that drives me nuts. The scenario is at work I run my MacBook Pro's display as the secondary monitor to a dual-monitor setup. I primarily use the secondary view for my social network windows (Adium, Tweetie, Gabbble, and IRC). I position exactly as I want them to see all at the same time. However, when I disconnect my MBP to go home and reconnect to my other monitor at home, all the applications were shifted onto the main screen (since that is where they went when I disconnected the monitor before I left). With this, I have to go through the whole process again to move and position them on the secondary screen again. Is there a utility or application that will allow me to create screen/window profiles that will basically memorize the current position of all the windows and persist it to be re-instantiated later?

  • GF 3.0.1 + Virtual Server: www.myhost.com:8080/projectname-war => www.myhost.com. How?

    - by Harry Pham
    I need to change www.myhost.com:8080/myproject-war to www.myhost.com. This is what I try. In admin console in Glassfish 3.0.1, I create a http-listener-3 with port 9090 and address 0.0.0.0 (I want to have port 80, but got access-denied or some sort). I then create a virtual server call scholar, with Id=scholar, Hosts=${com.sun.aas.hostName}, Network Listeners: http-listener-3, Default Web Module=project#project-war.war(it is the only option from the drop down list since I only deploy 1 app). Then under Applications, I set the virtual server of the application to be scholar. Save and restart. I try localhost:9090, and expecting that it will load my project like as if I type localhost:9090/project-war. But it does not. I already set the Default Web Module, to be the project, why doesnt it load the project by default?

  • Program to see, which programs use the internet-connection?

    - by Martti Laine
    Hello Few days ago I opened my computer as I always do after school, and got pretty amazed about my 1.27kb/s download-speed. It has continued for few days already. We have a wireless network, which is used by 3 computers. Normally I've gotten 200kb/s (I think we have a 2mb-connection) but now it just suddenly slowed down. My friends have the same service-provider, but no problem. So, is there any kind of program, which would show me all the programs using connection and how much. It must be a program open which just takes all speed off. Any help is appreciated, Martti Laine

  • Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

    - by user12611315
    The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

  • replacing 3 Cisco Catalyst 4500

    - by hoberion
    Our network supplier recommends replacing our 3 cisco catalyst 4500's because they are EOL and dont speak OSPF (which we really want) Its not my area of expertise so I cant say for sure if we really need to replace these units but for my company the estimated costs of 250K euro is a huge problem. Is there any way to cut down on costs (without moving from cisco devices), I heard the 4500´s can speak ospf but would need an upgrade of sorts? edit: version: IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(20)EW, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1) supervisor: WS-X4013+ Cisco Catalyst 4500 Series Supervisor Engine II-Plus density: WS-X4306-GB Cisco Catalyst 4500 Gigabit Ethernet Module, 6 Ports (GBIC) WS-X4306-GB Cisco Catalyst 4500 Gigabit Ethernet Module, 6 Ports (GBIC) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45) WS-X4548-GB-RJ45 Cisco Catalyst 4500 Enhanced 48-Port 10/100/1000 Module (RJ-45)

  • Connection string during installation

    - by anon2009
    Hi, I've been convinced to use windows setup files(msi) for the installation of my new windows forms application after I asked a question here and got some excellent answers (thank you all): http://serverfault.com/questions/97039/net-application-deployment Now i have a different question: My application will need to access a SQL Server to provide users with data, which means that the connection string must be stored in the client's app.config file. How should I handle this? During installation, the user enters the connection string to that database? How they get the connection string? In an email from the admin? What if the admin wants to use SQL authentication and need to put the user info at the connection string? So you know, the app will be sold via the internet, so I don't have any access to the admins or the network. Any suggestions? Thanks in advanced.

  • How can I migrate websites between two identical servers?

    - by edude05
    I have two servers that have a nearly identical (software) configuration. We are upgrading the web servers to run windows server 2008 R2, one already is however the main one (that currently has sites) is on WS2008. Now, the old server is ns.mydomain.com and the new server is ns1.mydomain.com. Since dns automatically fails over to ns1.mydomain.com I'd like a way to move all the vhosts to the new server. Is there an automatic way to move / recreate all the vhosts on the new server? I have figured out how to migrate the DNS records already DNS Migration and since both servers are on the same private network migrating the website data isn't a large issue. Every site is running PHP & MySQL and the MySQL server is external so the records won't have to be moved. Thanks

  • Wordpress multisite and redirect

    - by Dr I
    I come to you because I'm facing a really strange effect on my hosting. I currently manage a server contening a NGINX/PHP-CGI and a wordpress multisite in it. My sites are created using subsite.domaine.tld, for now, my three subsites are correctly accessibles through the url: subsite.domain.tld. My goal is to allow my subsite on the host domain to be access through their respective unique domain. For exemple: www.domainA.com would redirect to subsite1.host.domain.tld. If I do that using the following setting on the domainA Public DNS: www 10800 IN CNAME subsite1.host.domain.tld. When I try to access www.domainA.com I don't go to subsite1.host.domain.tld but instead I'm redirect to the Wordpress ROOT site where I create my Network (host.domain.tld). Is there a trick to deal with?

  • What's so bad about pointers in C++?

    - by Martin Beckett
    To continue the discussion in Why are pointers not recommended when coding with C++ Suppose you have a class that encapsulates objects which need some initialisation to be valid - like a network socket. // Blah manages some data and transmits it over a socket class socket; // forward declaration, so nice weak linkage. class blah { ... stuff TcpSocket *socket; } ~blah { // TcpSocket dtor handles disconnect delete socket; // or better, wrap it in a smart pointer } The ctor ensures that socket is marked NULL, then later in the code when I have the information to initialise the object. // initialising blah if ( !socket ) { // I know socket hasn't been created/connected // create it in a known initialised state and handle any errors // RAII is a good thing ! socket = new TcpSocket(ip,port); } // and when i actually need to use it if (socket) { // if socket exists then it must be connected and valid } This seems better than having the socket on the stack, having it created in some 'pending' state at program start and then having to continually check some isOK() or isConnected() function before every use. Additionally if TcpSocket ctor throws an exception it's a lot easier to handle at the point a Tcp connection is made rather than at program start. Obviously the socket is just an example, but I'm having a hard time thinking of when an encapsulated object with any sort of internal state shouldn't be created and initialised with new.

  • How Do I Change the Windows7 LAN Proxy Config from the Command Line

    - by david.barkhuizen
    In Windows7, Is it possible to define/change the proxy config from the command line ? So, using the gui, I would go: Start Control Panel Network and Internet Internet Options Connections LAN Settings and then - enable/disable the proxy - define IP:port of proxy server But I would like to rather do this from the command line (so that I can run the command from a batch-file with a shortcut key - enabling me to switch proxy configs using a short-cut, rather than having to wade through the MS wizard). I've looked at using netsh.exe to change the settings for WinHTTP, but this seems to be thr wrong thing to do, as the WinHTTP setting do not appear to be related to the LAN settings. Much appreciated folks.

  • tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

    - by Ajit George
    I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues?

  • Cannot connect to a VPN server - authentication failed with error code 691

    When trying to connect to a VPN server, I get the 691 error code on the client, which say: Error Description: 691: The remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remote access server. Now, I validated that the username and password are correct, and tried to login with domain name and without. I also installed a certification to use with the IKEv2 security type. I also validated that the VPN server support security method. But I cannot login. In the server log I get this log: Network Policy Server denied access to a user. The user DomainName\UserName connected from IP address but failed an authentication attempt due to the following reason: The remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remote access server.

  • Modded Portal Gun Levitates a Companion Cube [Video]

    - by Jason Fitzpatrick
    This cleverly designed Portal gun prop levitates a model Companion Cube; the whole setup just begs to be paired with a Halloween costume. Courtesy of Caleb over at Hack A Day: I was out to lunch with a couple friends, brainstorming ideas for fun projects when one of them says “Wouldn’t it be cool if we could build a working gravity gun?”. We all immediately concurred that while it would in fact be cool, it is also a silly proposition. However, only a few seconds later, I realized we could do a display piece that emulated this concept very easily. Floating magnetic globes have been around for quite some time. I determined I would tear the guts out of a stock floating globe and mount it on a portal gun, since they’re easier to find than a gravity gun. I would also build a custom companion cube to be the correct size and weight necessary. Watch the video above and then check out the link below for more information on the build.

    I am looking to write a batch or vbs script to gather all users (local to the server. ie. administrators or a local account(not ad users)) on a collection of servers inside my network. I assume I could do this by subnet. Could even put the server names into a csv text file for the script to read from and report back to. Lots to ask. I would use net user however I run into local access only. Ideas? Or too many security walls to work?

  • How is"cloud computing"different from "client-server"?

    - by BellevueBob
    Watching a CEO for a new "cloud computing" company describe his company on a finance TV program today, he said something like "Cloud computing is superior to old-fashioned client-server computing". Now I'm confused. Can someone please explain what "cloud computing" means in contrast to client-server? As far as I understand it, cloud computing is more of a network services model, such that I do not own or maintain the physical hardware. The "cloud" is all the back-end stuff. But I still might have an application that communicates with that "cloud" environment. And if I run a web site presents a form that a user fills out, pushes a button on the page, and returns some report that was generated by the web server, isn't that the same as "cloud" computing? And would you not consider my web browser as the "client"? Please note my question is specific to the concept of "cloud computing" with respect to "client-server". Sorry if this is an inappropriate question for this site; it's the one closest in the Stack universe and this is my first time here. I'm an old timer, programming since mainframe days in the late 70's.
