  • websites resolving in browser but not resolving in CLI. Can ping IP but not domain name (unknown host)

    - by tjkoding
    Hi guys I'm currently developing using rails and for some reason bundle install is returning the following output Error Bundler::HTTPError during request to dependency API Fetching full source index from https://rubygems.org/ Could not reach https://rubygems.org/ I've discovered that pinging by domain name keeps returning an unknown host. The browser is still resolving web pages just fine and I've managed to confirm that the problem is localized (i.e. the rubygems page isn't down). I'm completely lost so any help would be much appreciated. Thanks in advance!

  • cant access my local web server with the external IP

    - by TommyG
    I havent been able to find a solution to my particular problem. I have a MAC which I set up as a web server and configured my router to forward to the local IP. When trying to access my site from outside, it does say "It works!", however, when I call a simple Hello World PHP script that I have, I am getting an error that the page could not be opened. I did enable PHP on my machine so thats not the problem. I really have no idea how can I access - I followed so many tutorials and did everything correctly. My router is a Linksys WRT160N if it matters at all. In the port forwarding section, I selected to forward

  • Port forwarding stopped working in my Linksys WRT54G2 Linksys router.

    - by user23490
    How to do it again? I had simply forwarded needed ports (e.g. for counter strike, ftp, http etc)) but now with same system, same OS and same router and settings, it's not working. Tried setting router to "factory defaults" and do everything again. However other jobs are being done like it is connecting to my DSL ISP and I can access Internet easily. Still no success. PS. I tried on both Windows and Ubuntu. On Windows I use it for Counter Strike and others (e.g. host my local FTP server) on Ubuntu.

  • How can I retrieve "remembered"(stored) wi-fi password from a win. 7 device?

    - by user180880
    I have access to PC, and I am a standard user. Everything(incl. "show charecters" tickbox at wiriless menu) requires admin access. Now, that said machine is actually like a big tv with touch. Type-stuff is handled by virtual keyboard of windows. I can reach to c:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces and can see-open files there, which is I assume where passwords stored are. Now the problem is that these passwords is encypted. I'm ok with if there is a way with changing/resetting admin password as well. Considering this device has nothing but massive amounts of usb(yep, not even cd-dvd // rw) the only way is from inside or with usb without admin rights.

  • Is it possible to combine a list of torrents into one torrent with many files, keeping the seeds?

    - by Zequez
    Let's say you have all the episodes of FOO series that you downloaded as they were out, so you have like 20 torrents. Now let's say you want to make a bundle torrent with all the files, call it "FOO Season 1", and then send it to someone. One way would be to create a new torrent with all the episodes, but you would lose all the seeds from the current torrents, and you also couldn't seed people that want to download single episodes. Is this possible with the BitTorrent protocol?

  • How does Google manage to serve results so fast?

    - by Quintin Par
    I am building an autocomplete functionality for my site and the Google instant results are my benchmark. When I look at Google, the 50-60 ms response time baffle me. They look insane. In comparison here’s how mine looks like. To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare From a server side perspective I don’t think I can do anything more. Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance?

  • Can I use Server Monitor with a non-server Mac?

    - by Chris
    I have a computer I use as a simple file and web server. I am simply desiring to be able to monitor load, traffic, memory usage, etc via Server Monitor. I have also downloaded an app for my iPhone which does the same thing, but it uses the same protocol that Server Monitor does. Is it possible to get Server Monitor to recognize my non-server box as a server so I can monitor this information? For reference, I am running 10.4.11 on this PPC box. Thanks in advance!

  • Level 3 Communications Monitoring

    - by thursdasy
    Does level 3 Communications offer any type of map of current network status? It seems our connection here is getting high latency through their network. Also what is the experience asking them questions about if one of their appliances is malfunctioning or being overloaded because you are receiving bad latency in their network?

  • Can I wake up PC/laptop on remote printing request?

    - by dzieciou
    I have an old Epson printer that does not have network adapter, only a USB socket. I have also a computer with network card. I could combine them to put this printer in my local network, but then I would need to keep the computer always up and running. That's definitely not economic. Is there a way to wake up computer when printing request arrives? Something like Wake-on-LAN? Or I am forced to use additional hardware?

  • Cannot open /dev/rfcomm1 : Host is down

    - by srj0408
    I am working on raspberry PI and on Bluetooth. I am using old raspberry pi kernel as the new one has got some bugs that were not resolved with respect to the bluez daemon. At present my kernel version is 3.6.11. I am using a USB bluetooth dongle and my sole purpose is to auto connect the bluetooth dongle when ever it is in range. For that i think i have to run a script in the backend on RPI that will keep on checking the existence of usb bluetooth dongle. I started from the very scratch. I installed bluez daemon using apt-get install bluetooth bluez utils blueman and then i used hciconfig which gives me that my bluetooth usb dongle is working fine. But when i did hcitool scan , it give me no device in range even though my Serial bluetooth Device was on. I wasn't able to find any device in vicinity. Also when i unplugged and plug the USB dongle again, i was able to scan the serial device , but when i repeat the process, i find the earlier condition of not finding any deice. I had find another useful link, but that need address of the bluetooth device that need to be connected. I want to automate this using hcitool scan, storing the output to the a file and then comparing it with already paired devices and their name. For that i need to figure out why hcitool scan is sometime working and sometime not. ? Can some one help me in figuring out why this is happening. Is there any problem on hardware side i.e Bluetooth dongle is buggy or i had some problem in bluez utils. Edit 1: While as of now, hcitool scan is giving me my remote device address but still i am getting the same issue of HOUST IS DOWN, '/dev/rfcomm1'. I am really not getting any idea of what to be done.

  • Colliding network addresses

    - by joepd
    A customer is using the same address space as the company network. I need to connect with Cisco VPN Client to the network of the customer, without affecting local connectivity. To keep all working, I connect from a VM to avoid network addressing collisions. This works, but I'm looking for a way to get rid of the VM. Is it possible to connect with Cisco VPN Client 4.8 from Windows 7, without changing the 'normal' routing? How to tell specific applications (most importantly: Putty, VNC, mstsc, psql) to resolve their routes to the VPN instead of the default network interface? Have been hearing about SOCKS-proxies, is that something that could be made to work? I fear that this is a a bit of a crude question, but I'd be happy to specify more details/context.

  • Randomly unusable wireless connection. Oddest issue ever...

    - by Hallucynogenyc
    I have two desktop computers a laptop and a smartphone. All of them connect perfectly to my router (WRT54GL with Tomato firmware), but randomly (once a week maybe) something odd happens: For over an hour or so one of the desktop computers (Windows 7 Pro x64) will just refuse to connect properly to the router. Only that computer and only to that network. I can connect all the other machines to the router perfectly and I can connect properly to other networks with that machine. What I mean by "not being able to connect properly" I mean that the OS will just tell me "not able to connect to.." or that it will connect but then say that it has no Internet access or it connects but will then take minutes to load any website, even the router web interface. I've tried to change from WPA2 to WEP and back to WPA2, I've tried different network adapters (one internal PCI card and one USB external card), removing networks from Windows and adding again... without making any difference. It works for some days but at the end, it ends happening at some time. I just have no clue on what the hell could be going on here. I first thought it was the network adapter, then the router, then Windows... Thanks in advance

  • How can I make the Windows VPN route selective traffic (by destination network)?

    - by Legooolas
    I want to use a windows VPN but only for a particular network, so that it doesn't take over my entire network connection. e.g., Instead of the VPN becoming the default route, make it only the route for 192.168.123.0/24 (I can see that there is a solution for this for Ubuntu in this question, but sometimes I have to do this on Windows too) Can this be automated so that whenever I connect to the VPN it does this?

  • Will a `wireless n` network adapter work `wireless g` router?

    - by ShoeLace1291
    I have verizon fios internet service. I believe they use a Wireless G router, but I just have one question. I currently am using a 54mbps wireless pci adapter in my Windows 7 custom build. It drops the internet connection all the time and is starting to get very irritating. I'm thinking about buying a new one, but all the 300mbps cards on newegg are wireless n. So my question is, will a wireless n network adapter make a difference with a wireless g router?

  • SAN for Medium Business - Where to start? [closed]

    - by Henson
    I've always run Linux on my home computers, and done PC repair for years, but this is my first experience with needing to buy a SAN. I thought I was knowledgeable, but I feel a bit lost. I need to be able to support 25 VMs, which are currently managed through vSphere. The company I'm at is growing quickly though, so I'd like to plan for the future. Ideally, I want a solution that I can just tack arrays onto and manage as one large, iSCSI drive. Suggestions? Good resources? If I can find something that appears to software as one large drive, am I better off going with a solution like FreeNAS or Starwind, or an all-in-one proprietary solution like NetApp? Cost, is (of course, and always I'm sure) an issue.

  • Network configuration for several LANs and a shared server

    - by Grodriguez
    I want to setup a network on a building to provide shared services to all homes within the building. This should work as follows: Each home has a private LAN (e.g. 192.168.0.x) and an ADSL router for Internet access. Private LANs from each home should not "see" each other. There will be a shared server on the building which must be accessible from every home. I am not sure what is the best way to achieve this. Can someone point in the right direction? Thanks.

  • Migrating Split Access Database from one domain to another (not working, details in Q)

    - by Expo_Rob
    Some background: I'm a programmer, not a network administrator, who has been asked to migrate some accounting software (Integrated Office Accounting version 3.2) from an existing domain (OLD_NETWORK) to a new domain (NEW_NETWORK). No-body at the office knows how it works under the hood. It is a split Access 2000 database with the back-end shared and on a file server (which is also the DC) using mapped drives. The DC is NT Server 4 SP 6. The new server is server 2003. The two networks are running independently (ie: two computers on each desk). I have been able to get new computers set up on NEW_NETWORK and working with the IOA software just perfectly but for one problem: The company here uses other entirely separate databases which access the tables IOA maintains (specifically the 'customers' table) via links. To switch between these systems, you press F11 then File-Open the appropriate database and away you go (this is necessary to maintain the permissions that the IOA system uses to protect the customers table). The entire database is Access 2000, the links go to other Access databases, SQL-Server is not involved in any way, nor is a migration to SQL server likely. If I can't migrate anything over, everything will stay as it is, and the NEW_NETWORK computers will not be used. The problem: When I try and update these seperate databases (I shall call one "BANK_ACCOUNT", but the name does not matter), it says "this recordset cannot be updated". It also will sometimes not pull information out of the 'customers' table (ie: date_entered) when looking at a report of everyone who opened a bank account on a certain day (ie: today). I have tried: Giving 'everyone' full control via. shared directory permissions Giving 'everyone' full control on a file system level Checking the permissions within Access (everyone has full read/write on all tables) Copying the entire server contents from one file server to another (ie: xcopy everything) Copying the entire local client files from one computer to another, putting them in the exact same position in the file system, with the same permissons (or full control to 'everyone'). Running as an Administrator Taking one of the NEW_NETWORK computers, having it join OLD_NETWORK and run the software (direct copy from a working system with identical drive mappings), this did not work Weeping openly My Question: Is there anything else I can try? (sorry for this being so long)

  • unable to ping machine on WLAN

    - by N.M.
    I've started accepting remote desktop connections on one of my machines. If i connect the machine to my router using an Ethernet cable i am able to ping it and connect to it remotely (using RDP). However, if i connect the machine using wireless network i am unable to ping it (or access it using RDP). Although i can live with connecting that machine using an Ethernet cable i just wanted to know the reason why it doesn't work using wireless. Is the router not able to forward packets to that host if its connected using wireless? If yes, any solutions?
