  • Can't access DD-WRT set in DHCP forwarder

    - by Chris Marisic
    This might sound amazingly stupid but I have a DD-WRT (micro) router that I placed in my network to act as a switch and as a WAP while relying on my cable modem to be the DHCP server. In my attempts to get the configuration right I put the router into DHCP forwarder which then made everything work correctly. The problem is now I can't seem to connect to the router in any fashion to add mac addresses to the WAP access list. Is there something I'm missing or do I need to try a hard reset on it and reconfigure everything?

  • 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)

  • Adding a Printer to my Print Server Failing

    - by Rudi Kershaw
    So, on the Windows Server page I read the following. Step 4: Add Network Printers Automatically Print Management (Printmanagement.msc) can automatically detect all the printers that are located on the same subnet as the computer on which you are running Print Management, install the appropriate printer drivers, set up the queues, and share the printers. To automatically add network printers to a printer server Open the Administrative Tools folder, and then double-click Print Management. In the Printer Management tree, right-click the appropriate server, and then click Add Printer. On the Printer Installation page of the Network Printer Installation Wizard, click Search the network for printers, and then click Next. If prompted, specify which driver to install for the printer. So, I have got to this point, made sure the printer (Canon MP620) is on and correctly plugged into the network. However, when I click "Search the network for printers", the wizard doesn't find it. Now, I can't get any further. Is there anything I could be doing wrong? How should I proceed moving forwards?

  • How do I force specific permissions for new files/folders on Linux file server?

    - by humble_coder
    I'm having an issue with my install of Ubuntu 9.10 (file server) and its samba permissions. Logging in and reading works fine. However, creation of new directories by users restricts access for other users. For instance, if Bob (Windows user who maps the drive) creates a folder in the directory, Jane (Mac user that simply smb mounts) can read from it, but can't write to it -- and vice versa. I then must go CHMOD 777 the directory for everyone to be happy. I've tried editing the "create/directory mask", and "force" options in the smb.conf file but this doesn't seem to help. I'm about to resort to CRONTABing a recursive chmod routine, although I'm sure this isn't the fix. How do I get all new items to always be 777? Does anyone have any suggestions to fix this ever-occurring situation? Best

  • Configure TCP/IP to use DHCP and a Static IP Address at the Same Time

    - by Tiago
    My computer is configured to obtain a IP address automatically using DHCP. It only has one network adapter. How to configure an additional static IP address? I found a tutorial for Windows XP, but the procedure didn't work for Windows 7. Is it possible to configure two IP addresses on Windows 7, one being static e another being dynamic? How? The dynamic address I got now is 10.17.11.162. The static IP is 10.17.30.19. The network mask is the same: 255.255.224.0. Both work independently, but I don't know how to use both at the same time.

  • How to monitor the network traffic on a router?

    - by Adi
    Here's my current network set-up: we have 3 users connecting to a Thomson Gateway router (TG585 v8) provided by my ISP. We are connecting over an ADSL line. The problem is that we have a limited data allowance (60GB) and we always exceed it. I would like to monitor how much traffic each computer makes. The best solution would be to install a software on the router (like OpenWRT) which would monitor how much traffic each computer makes. But I couldn't find any replacement firmware that would support my router. The other solution would be to install a software on each machine and then collect all the data at the end of the mount. But that's not a very good think to do. Plus, the users can always shut down the application. Any suggestions?

  • "The connection to the server was reset while the page was loading"

    - by andygeers
    I've just taken over managing the network for a small charity, and am finding internet access very flaky - we keep getting "The connection to the server was reset while the page was loading." errors (HTTP Error 12031 according to the Windows network diagnostic tool). It doesn't seem to be anything to do with our ISP since it also affects internal traffic (even requests to an Apache instance on my localhost!) Adjusting the MTU setting in the Windows XP registry sometimes seems to help for a few minutes after rebooting, but the problem always returns.

  • Why times elapsed connecting to a server are different?

    - by user1634619
    I have a small program which connects to a server of my choice and measures the time elapsed to do so. Each time I run it it returns different result. My question is what does this time depend on ? Network congestion for one. If I choose a server that has multiple addresses e.g. google.com the length of physical link may differ from time to time ? Is it safe to assume that it also affects connection time ? Are there any other factors in place ?

  • Problem with network after malware attack

    - by Cruelio
    Im trying to help some friends with a Win XP machine. I got rid of the malware using Malware Bytes, and HiJackThis. But now they(I) have another problem. When the computer boot into Windows it seems fine. When I start Internet Explorer the browser window opens just fine, but nothing happens for at minute or two. After the two minutes of waiting, the network icon appears in the taskbar next to the clock, and then everything works. The computer is connected to the internet using a Ethernet adapter. I have looked at the Rvent Log and found an error from Perfnet with eventid 2004 <Provider Name="PerfNet" /> <EventID Qualifiers="49152">2004</EventID> <Level>2</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> What I have tried so far: In the device manager i have uninstalled the Ethernet adapter and installed it again. I have uninstalled and installed the Windows File and Printer Sharing service. I have verified that both server and workstation services are started. What should I do next?

  • Routing RFC1918 addresses through dd-wrt via a switch

    - by espenfjo
    I am a bit stuck with an experiment of mine. I have a network looking somewhat like this. | Internet | | ---- |Switch| ---- | | Server w/pub IP | DD-WRT router 192.168.1.1 | | RFC1918 clients 192.168.1.0/24 What I want is for the RFC1918 clients to speak directly with each others. On the server with the public IP I have this route: 192.168.1.0/24 dev eth0 scope link and can see that packets are infact reaching the dd-wrt router for 192.168.1.1, even though if I get no answer. Trying to reach one of the RFC1918 clients from the public IP server will get no result, as the dd-wrt router is not announcing that network on to its external interface (arp who-has 192.168.1.107 tell xxx.xxx.xxx.xxx, but no answer). The router being an WLAN dd-wrt router has of course a load of routes, VLANs and interfaces: xxx.xxx.xxx.1 dev vlan2 scope link 192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.244 84.215.64.0/18 dev vlan2 proto kernel scope link src xxx.xxx.xxx.xxx 169.254.0.0/16 dev br0 proto kernel scope link src 169.254.255.1 127.0.0.0/8 dev lo scope link 0.0.0.0 via xxx.xxx.xxx.1 dev vlan2 xxx.xxx.xxx.xxx being the public IP, and xxx.xxx.xxx.1 being the default route for the public IP. I am not sure where to continue with this. I would recon that I both need routing on the dd-wrt router, as well as some iptables magic? Why do something this complex? Why not ;) Also, do not mind that "Internet" can get RFC1918 traffic, it wont go outside of the walls. EDIT 1: Following the tip from stew I do indeed get the correct ARP flowing. And adding an iptables rule for allowing traffic from that specific public IPd machine I get traffic between the systems! Oddly enough though, the speed I get from Server w/pub IP - RFC1918 clients are the same as if the traffic were routed out onto the Internet and back. Edit 2: Ok, disconnecting the external Internet connection will still give the same, crappy transfer speed. So it has to be something else. Edit 3: Ok, I guess there are other reasons for this crappy speed. Case closed. :)

  • How to connect cable internet on ubuntu

    - by NAVEED
    I was using my cable internet on windows and it was working. Now I moved to ubuntu for development work. But I am unable to connect this internet on ubuntu. I called their technical support and they ask me to install PTPPN (I have forgot the exact name) and then provide our server name, your username and passowrd. I download that software PTPPN(whatever) by using a debian file but I did not find it after installation. I tried to contact to technical support again but unable to connect. Can someone please tell the exact name of that software and how to install and then connect to internet on ubuntu? I have only the following information for now: Install "PTPN" on ubuntu. (forgot exact name of this package) servername: blue.connect.net.pk username: myusername password: mypassword Thanks

  • OpenWrt Backfire 10.03 Frequently Becoming Unresponsive (Bridged Client)

    - by Christopher Parker
    I have a Linksys WRT54G version 2 that I've flashed with OpenWrt Backfire 10.03. It's acting as a bridged client using the wl.o driver to give me network access in my home office, which is in a far corner of my house in a position that would make it exceedingly difficult to fish network cabling in through the walls. I have three network-ready devices attached to the device that don't currently support WiFi, including a networked printer. Ever since I migrated from WhiteRussian, which was also set up as a bridged client, to Backfire, the device has been becoming unresponsive, as though the OS itself has crashed or frozen. The WLAN light becomes completely solid and the LAN lights stay mostly solid, blipping off and then back on again maybe once a second or so. They all blink more or less in unison. Is there some way I can diagnose why this is happening so I can fix it? Right now, the only way to fix it is to unplug the device and plug it back in.

  • Windows 7 Administrator HomeUsers Account

    - by Charles Carrington
    I'm trying to login to my Windows 7 PC from another PC so that I can transfer files to the Windows 7 PC. I've just installed Visual Studio 2008 on my new PC, and I wan't to transfer all of my work from my old machine to my new one. When I first set up a user on the Windows 7 PC after a reformat, the account created had a Group field that read "HomeUsers; Administrators" when viewing it from the User Accounts screen. You get to this screen by typing "netplwiz" in the search field of the Start Menu. I changed the Group of this account to Administrators before I realized that it was assigned to two Groups -- "HomeUsers; Administrators" as I mentioned above. I was trying to make sure that it was an Administrator account so I didn't have to type in a password everytime I wanted to install software. I can use this computer normally without being asked for an administrator password all the time when I want to install new software, but I can't log in to this PC from another PC because I don't have an account that has a Group of "HomeUsers". I should have left the account alone; everything would've been fine. But there doesn't seem to be a way to assign it to two groups after the initial assignment that take place automatically when you are setting up your computer for the first time. If you assign "HomeUsers" to the account, the Group field on the User Accounts screen will just read "HomeUsers". If you assign "Administrators" to the account, the Group field on the User Accounts screen will just read "Administrators". There's no way to make it read "HomeUsers; Administrators" again. If you don't have at least one account that is a "HomeUsers" account, you cannot log in to the PC from another PC on the network. If you don't have an account that is an "Administrators" account, you cannot install software on your machine without being asked for an Administrator password all the time, which is very annoying. I want an account on my Windows 7 PC that I can use to install software without being asked for a password AND that I can log into from another PC on the network to transfer files. If I could make the Group field read "HomeUsers; Administrators" of my primary account on the Windows 7 PC when I go to the User Accounts screen by typing "netplwiz" in the search field of the Start Menu, my primary account would do what I want it to do. Does anybody know how to make an account in Windows 7 a "HomeUsers" account AND an "Administrators" account? As I said before, Windows 7 does this for you automatically when you first set up your computer. But if you change it inadvertently, there is no way to change it back. At least I don't know how to do it. If anybody has any ideas on how to fix this, I would greatly appreciate it. Thanks, Charles Carrington

  • Windows 7 Homegroups not working?

    - by Jonas
    I've got a homegroup set up, and only the accounts/machines where the user and password is identical can see/share files. I thought the setting to let homegroup control the accounts would make that requirement unnecessary....am I missing something? To be clear: I can see the other machines/user accounts in my homegroup listing, but I can't see any of the files in their shared libraries.

  • Do all the network cards use the same frequency to send signals to wire?

    - by smwikipedia
    I am comparing my cable TV wire to my network wire. In a TV cable wire, different frequencies are used by different TV channels. And since a certain channel use a fixed frequency, I think the only left way to represent different signal is with the carrier wave's amplitude. But what about the network wire? For all the network cards with the same type, do they also use different frequencies to send signals just like TV cable? I vaguely remember that they use frequency adjustment to represent signals. So the frequency should not be a fixed one. So how did all the network cards that sharing the same medium differentiate their own signal from others?

  • Multicast in private LAN with different subnets

    - by Gobliins
    after i read Multicast IP Addresses and Multicast accross the subnets I am confused. Configuration: I have two devices in the same network. They may not be in the same Subnet, but always in the same physical network (beyond the same router, switch etc.) I want to communicate across IP multicast either 224.x.x.x or 239.x.x.x may be more fitting because we want it local, not beyond of forward through the router. Can one machine be the receiver and the other machine sender of the same multicast address? and can the receiving machine send an answer to the sending machine?

  • Why would one of my servers stop being able to access other servers by FQDN?

    - by Newlyn Erratt
    I have a number of servers on our local network and our debian server has suddenly stopped being able to access the other servers via their FQDN. Initial symptom was inability to login with Active Directory accounts. On further inspection, this machine, porkbelly, was unable to access our other servers (e.g. bacon and albert) via their FQDN. That is, they can ping albert by running ping albert but not by running ping albert.domain.local though when running ping albert it will be expanded to albert.domain.local. The server is still accessible from other servers via both porkbelly and porkbelly.domain.local. Upon examination of hosts information and running hostname its hostname and FQDN are correct. The resolv.conf appears correct. It contains: domain domain.local search domain.local nameserver 192.168.0.xxx (the nameserver) The dns server is also our Windows AD server. I'm not even sure where to go from here or why dns seems to be partially working though I don't have much experience. Where should I go from here? What might be causing this issue where machines are visible via their hostname but not their FQDN?

  • Facebook doesn't work on computer, but work on mobile device, both use the same router

    - by sasa
    I have a very strange problem and I'm thinking that can be problem with dns or something similar, but not sure and don't know how to solve. My computer is connected to router and every site works fine except facebook (Chrome and Firefox). Chrome shows "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." But, on mobile device witch is connected to the same router facebook works fine (Fb application and Delphin browser). Pinging facebook works fine. Clearing cookies and cache didn't help. Also, I performed antivirus and antimalware scan and there is nothing. What can be a problem? Update: I'm also connect notebook on that wifi router, and on it works fine. nslookup facebook.com Server: UnKnown Address: 192.168.1.1 Non-authoritative answer: Name: facebook.com Addresses: 2a03:2880:2110:3f01:face:b00c:: 2a03:2880:10:1f02:face:b00c:0:25 2a03:2880:10:8f01:face:b00c:0:25 69.171.224.37 69.171.229.11 69.171.242.11 66.220.149.11 66.220.158.11

  • Need help using a super scope

    - by Vdub
    I have a windows server 2008 r2 standard running our DCHP, DNS, and AD. also I have (3) HP Pro Curve 2510-G switches (J9280A). Right now our LAN is set up 192.168.50.2-192.168.50.254 on our sub-net (A) and another scope with 192.168.51.2-192.168.51.254 sub-net (B) both have sub-net mask of 255.255.255.0. The same server is our DNS which is 192.168.50.242 and our firewall (watchguard) is the gateway at 192.168.50.1. Right now the sub-net (B) does not have DHCP active so only sub-net (A) is giving a pool. My problem is that we are trying to have open WiFi on our network and i am assuming that i can use the sub-net (B) for that if i activate it and use sub-net (A) for our staff only. I have noticed that when i set up a static on a client pc and set it to 192.168.51.x i cannot use the DNS of 192.168.50.242 however i can use 8.8.8.8 and it works fine, i am guessing that because it is on a different sub-net? Forgive me as i am very new at this and dont know a lot. Is there easy way with the equipment i have to a accommodate wifi for hundreds of people without causing problems for our staff? (multiple same IP address assigns) I appreciate any and all info!

  • UAE and the mysteries of unreachable websites

    - by 0plus1
    I write here because I'm really lost, please stay with me because it's not easy to explain. A company asked me to set-up a private server, now I'm a programmer so I got a solution with technical support and cpanel which helped me to setup everything and it's working smoothless. I'm by no means a professional sysadmin, but I have a fair knowledge of server configurations, but this problem is way over my knowledge, and apparently way over the knowledge of most sysadmins, I really hope that here I'll find someone with enough experience to help me or at least give me more insight. Now this company for which I'm consulting operates in the UAE (United Arab Emirates) and from there the server is almost unreachable. It started with ns not registering in the UAE, after a week that sorted itself out and now the site is indeed reachable, but it takes almost 2 minutes to load a webpage with one line of text. Emails go in timeout. The domain currently parked there has been bought appositely for tests, the main one that was supposed to go there, after a catastrophic week has been transferred to a shared hosting solution in the UK, and from there it works like a charme. Now after doing some research I discovered that I'm not alone in this, there are several reports of webmasters discovering that their website is not reachable inside the UAE, and mind this has nothing to do with the state-wide block of questionable sites, because in that case an error message appears, this seems to be related to the infrastructure of the UAE, which apparently reroutes everything through their own "fake" internet. Apparently new servers with their own IP are not recognized (yet?) by the UAE infrastructure, while shared hosting solutions seeing that they operates tons of other websites are more likely to be part of the UAE network. Now my questions are: 1) Has someone a real explanation for this? The only thing I can think of is that the server is on a new IP that is not yet recognized by the UAE, but that doesn't explain why it loads (even if after 2 minutes). I don't have any help from within the UAE as the only people that are "experts" are questionable companies that simply try to sell their own services. 2) If there is really some kind of block of new servers, is it possible to know before if a server is reachable from within the UAE, currently this is not a ns problem as even accessing the server with its IP result in a 2 minute wait. 3) Can it be that the problem lies somewhere else? There are some tests that I can perform? I'm not physically in the UAE, but I can ask the people there, or use teamviewer. Could it be some misconfiguration on the server (mind that the site works EVERYWHERE else in the world). Thank you for ANY kind of help

  • What kind of router do I need to handle multiple external I.P addresses?

    - by user1308743
    I have 3 dedicated I.P addresses going to a location with a few servers, and 1 RVS4000 router. Right now, only one I.P is being used. I would like a router that can use all 3 I.P addresses and I can make rules like this: IP1:80 goes to ServerA IP2:80 goes to ServerB What kind of router/device with what features do I need to handle this? I will need to set 30-40 rules to forward certain ports to certain servers. Only a couple ports will need to go to IP2 or IP3. Thanks

  • How to connect to IIS and SQL Server Express on Windows 7 host from XP Mode

    - by SpatialBridge
    Hello, I am running IIS and SQL Server 2008 Express on my Windows 7 host, and I'd like to be able to connect to them in XP Mode. My host machine is not a part of a domain, only a workgroup. So far, I've tried these instructions on connecting to SQL Server, but I'm not able to telnet to port 1433 on the host from XP Mode. I'm also not able to connect using a SQL client. I'm not able to connect to IIS on the host from XP Mode. Advice from those who have had success doing this would be appreciated. Thanks, Jon.
