  • Multiple vlan issue with procurve switch

    - by Chris-AZ
    I have a cisco asa5505 as my rtr/fw(10.1.3.254). I have vlan 1 and vlan 3. Vlan 1 is my default all access vlan. Vlan 3 is my Guest(dmz) vlan. I can't seem to get a dhcp ip address when my laptop is plugged into port 42 on my procurve. I have plugged my laptop directly into the firewall and it gets a dhcp ip fine(the firewall is dhcp server). the firewall is plugged into port 41. Only vlan3 needs to go over port 41. I'm sure I have a bonehead config problem however I'm about ready to pull out what little hair I have left. vlan 1 name "Computers" forbid 45 untagged 1-41,43-44 ip helper-address 10.1.1.16 ip address 10.1.1.1 255.255.255.0 tagged 46-48 no untagged 42,45 exit vlan 3 name "Guest Wireless" ip helper-address 10.1.3.254 ip address 10.1.3.1 255.255.255.0 tagged 41-42,44-48 exit

  • How do I connect two computers with a LAN cable?

    - by John
    I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable. On the Windows XP machine, I set the IP address to 192.168.0.10. On the Windows 7 laptop, I set the IP address to 192.168.0.20. The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this. The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window: I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success. Please explain in deep details how to solve my problem so I can connect to my Windows XP machine. EDIT: Maybe this can help: the Windows XP machine is named 'I' and '???????? III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.

  • Set iDRAC IP Address on Ubuntu 12.04 without Reboot?

    - by BT643
    We have a Dell PowerEdge R720XD server and want to setup iDRAC, but this is a production server so we need to do it without a reboot if possible. We just need to set the IP address on the iDRAC but the servers do not have a front LCD panel so we cannot use this. The iDRAC will currently have the default 192.168.0.120 IP address but we are not on this IP range so cannot use this. We need to change it to 192.168.5.x. I've seen racadm mentioned, but before I start messing around installing this on Ubuntu, is this what we need? and will we be able to set the IP address on the DRAC with this? Thanks

  • Changing subnet-mask of class-c network host to 255.255.0.0

    - by Prashant Mandhare
    We have a existing class-c network with IP address range 11.22.33.44/24 (just for example). My domain controller has been configured within this subnet. So all servers within this subnet have subnet mask configured to 255.255.255.0. Now we have got a new subnet with IP address 11.22.88.99/24 (note that only last 2 octets have changed). I want all new hosts in this new subnet to join my existing DC. For this we have configured firewall properly so allow this. (so there is no issue with firewall). But initially I was not able to join hosts in new subnet in existing domain. Later I doubted on subnet mask used in domain controller (255.255.255.0) and for testing purpose I changed it to 255.255.0.0, it worked like charm, i was able to join subnet-2 hosts in subnet-1 domain. Now i am wondering whether it will be good practice to change subnet mask of a class-c network to 255.255.0.0? Can any issues arise due to this? Experts please provide your opinion.

  • Cannot connect to local network shares when connected to VPN. Error: "the user name could not be found"

    - by Nick G
    I keep finding that on our small company LAN (7 users, 3 servers) that some servers keep becoming "not accessible" for the purposes of file sharing. They display the message "\SERVER is not accessible. You might not have permission to use this network resource. The user name could not be found". But I don't know why "the user name could not be found" as all the machines are on the same domain and the PDC and BDC seem to be behaving OK. EDIT: VPN seems to be the cause: It turns out I can see the server if I use the IP address (\\1.2.3.4\ etc) or the FQ active directory name (eg \server.domainname.local) but not if I use the server name on its own or a mapped network drive originally created from the "short" name. Oddly though, my machine has no issue resolving the server's DNS name as I can ping the machine name OK and it immediately comes back with the IP, however nslookup seems to fail. It seems to be a problem with how Windows looks up machine names when connected to VPNs. When I'm connected to a VPN, windows seems to use the DNS assocated with the VPN and not the one on the domain controller. This behavior to me, seems incorrect as surely that would mean connecting to any VPN would break any ability to lookup local machine names for servers and printers etc. So I guess the real question now is, how can I make my machine still search the local Active Directory DNS (the PDC) even when connected to a VPN? More info in my comments below.

  • Setting up a software access point on Gigabyte GN-WPKG x64

    - by Reckage
    I'm using a Gigabyte GN-WPKG card on Windows 7 64-bit and was thinking it would be good to turn it into a wireless AP (I have a wired internet connection). Connectify, which would normally be the solution, says it's not compatible. There are instructions for setting up an AP, but they seem to be for 32-bit. I found the equivalent drivers for 7 and they don't seem to do anything. Is there no SoftAP for Vista and later on a Gigabyte card?

  • Best free (or cheap) ASP.NET based CMS for a club/association?

    - by marc_s
    I've been looking for a simple, intuitive ASP.NET based CMS to handle my club/association site. It should be based on ASP.NET so I can add some extra specific pages offer a membership system, e.g. I want to be able to define members which can e.g. comment posts, while anonymous users can only read (no active participation) have features like news, forums, blogs, picture gallery be simple and easy to use I've been looking at GraffitiCMS: so far my favorite, but it has no forum, and no membership system, and no future, it seems - no development whatsoever in over a year :-( Sitefinity: had extreme trouble even getting it installed, and when it's finally up and running, I find it overly complicated and not intuitive at all Umbraco: same problem - hard to install, hard to get up and running, the intro videos on their site are only available to paying subscribers (what's up with that deal???)..... DotNetNuke: seems like a major overkill Community Server: seems like a major overkill - and seems to be more and more commercial, only Any others I've missed that I should have definitely looked at ??

  • Wireless clients have no route to ethernet clients in OpenWrt router

    - by superjoe30
    I'm using OpenWrt Kamikaze 8.09 on a Linksys WRT54g v1.1 router. I just flashed it with default settings and got everything working, except my wireless laptop cannot ping my desktop which is wired to the router. What can I do to fix this?

  • Check packet vlan tag using Tap virtual interface

    - by ankit
    Hi all, I am trying to learn how to implement virtual interfaces using the Tap driver. So far my understanding is that using the tap driver I can create a virtual interface and then have a userspace program attach to this interface to analyse the data coming into this device. Now what if I attach a cisco switch to my LAN interface using a TRUNK link, forward all the packets coming into the LAN interface to the virtual tap interface and then in my program attached to this interface do some coding to analyze the vlan tag in the packet and only allow certain vlans to be forwarded to the WAN interface ? Does this sound plausible or is there is flaw in my basic understanding ? Thanks for the help! ankit

  • Reloading NAT configuration on a running VMWare Server 2.0.2

    - by Jonathan Clarke
    I have a server running VMWare Server 2.0.2. The host is Debian Lenny. I have 15-20 virtual machines running, all attached to a single NAT network (named vmnet8). I have configured VMWare's NAT (the vmnet-natd daemon) to forward some incoming to ports to one of the VMs, since it hosts some publicly accessible services. I did this via the file /etc/vmware/vmnet8/nat/nat.conf by adding lines like the following: 80 = 192.168.100.100:80 This works great, I can reach the web server on the VM at 192.168.100.100 by connecting to the host's IP address. Sometimes, I need to add port redirections to this NAT configuration. So, I add a line to the configuration file. Now for the question. How do I make the natd process take this new configuration into account? Clearly, restarting the host machine does take it into account, and the newly added port is forwarded. However, this is not an option on this server, so how should one do this without restarting the whole host? Thanks for any ideas!

  • iSCSI connection timing out on ESX 3.5 against a NetApp storage appliance

    - by Jesse1973
    I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts. The iSCSI network is segregated on a private network. Here is an export of vmkiscsid.log from last night: 2010-02-10-12:30:38: iscsid: an InitiatorAlias= is required, but was not found in /etc/vmware/vmkiscsid/initiatorname.iscsi 2010-02-10-12:30:38: iscsid: LogLevel = 0 2010-02-10-12:30:38: iscsid: LogSync = 0 2010-02-10-12:30:42: iscsid: Login Success: iqn.1992-08.com.netapp:sn.101197719,default,192.168.73.2,3260,2001, 0x1 2010-02-10-12:30:42: iscsid: connection1:0 is operational now 2010-02-16-02:03:35: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-02:03:39: iscsid: connection1:0 is operational after recovery (2 attempts) 2010-02-16-04:02:27: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-04:02:32: iscsid: connection1:0 is operational after recovery (2 attempts) Should i edit the timeout value on the ESX host for iSCSI? This may work around the problem but will not solve it.

  • Airport Extreme and Windows PC via regular LAN (not WIFI)

    - by Mr AJL
    So I got an airpoort extreme, and everything works beautifully on the mac, but my windows 7 PC which is connected via a regular ethernet cable can't see any network. The Win7 PC says there's no cable connected. Any ideas? Is there some kind of setting you have to enable with the Airport utility? I looked everywhere but can't find anything. Thanks!

  • How can I set up multiple dynamic users to update a single network's dynamic IP

    - by d3vid
    On my home network we are allocated a dynamic IP. I want to configure ddclient (or an equivalent) to send IP updates to DNS-O-Matic/OpenDNS only when I am on my home network. I do not want to send IP updates when I'm on my office network. Can this be done? I am prepared to use different FLOSS software or a different free DNS service. Additionally, there are multiple users who may be on the home network or away on other networks. How can we configure ddclient on each machine so that whoever is on the home network updates the IP (i.e. so we don't have to rely on a particular machine being on the network to update the IP). OpenDNS support have said we can't simply install updater software on each machine.

  • Why did MAC-Adress Cloning Fix My Router?

    - by FranticPedantic
    I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!

  • Cisco 837 not passing UDP traffic properly (was: DNS query problem)

    - by TessellatingHeckler
    We have a setup of ADSL line - Cisco 837 ADSL router - Zyxel ZyWall 35 firewall/NAT - Switch - LAN. It has been fine for years, suddenly DNS resolution stopped working from the LAN to public DNS servers. No changes that I know of, so I can't revert anything. Current behaviour: DNS requests from the LAN using TCP show up in the oubound firewall log, in the Cisco debug log, in the dns-server-firewall, in tcpdump on the DNS server, the answer comes back, it works fine. DNS requests from the LAN using UDP show up in the outbound firewall log, in the Cisco debug log, but does NOT show in the dns-server-firewall, not in tcpdump on the DNS server, times out. DNS requests from the Cisco using UDP show up in the dns-server-firewall and in tcpdump on the DNS server, answer received, works fine. netcat connections to port 53 or a random port by TCP show up in the dns-server-firewall netcat connections to port 53 or a random port by UDP do not show up in the dns-server-firewall Summary: TCP seems fine throughought. UDP works from the Cisco over the ADSL, and it works from the LAN to the Cisco, but it doesn't seem to cross the Cisco 837 properly. Update: confirmed with netcat that any UDP traffic from the LAN is affected, not just traffic to port 53. Update: If I change the firewall's external IP to any other IP in the subnet, this starts working. When I put it back, it stops working. I now suspect it's an ISP issue (does that sound plausible?), and am removing the Cisco config.

  • windows 7 no internet access

    - by Kyle
    Just did a fresh install of Windows 7, and the network and sharing center says no internet access. Disabling and enabling the adapter seems to fix the issue temporarily, but the internet stops working shortly after. I have installed the latest NIC drivers and have installed all Windows updates. I have also tried manually setting the ip/gateway/dns and running netsh int ip reset in an elevated command prompt. I am running Windows 7 Home Premium 64bit with a wired connection. I have searched for hours, but have found no working solutions. Does anyone have any ideas?

  • How does Subnetting Work?

    - by Kyle Brandt
    How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself. What is classless routing and why is class-based routing obsolete? If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? Not looking for links to other sites (unless maybe you have one post with a bunch of good ones). I already know how to subnet, I just thought it would be nice if Server Fault had a generic subnetting answer.

  • Permanently change IP address on SuSE 10

    - by Long Ngo
    I am trying to change IP address of a SuSE 10 machine that is running Tomcat. I need to create a shell script to do this so could not use YaST. As some sites suggested on my Google search, I edited the files in /etc/sysconfig/network/ifcfg-eth-* to change the IP address. After that, I restarted the network service by calling /etc/init.d/network restart. The network card restarting just fine. I, then, restarted tomcat web service. However, when I browsed the new IP address using browser, I got an "Request denied" message. Can anyone please tell me how I could do this? Thanks

  • Setting up Windows 2008 with VPN and NAT

    - by Benson
    I have a Windows 2008 box set up with VPN, and that works quite well. NPS is used to validate the VPN clients, who are able to access the private address of the server, once connected. I can't for the life of me get NAT working for the VPN clients, though. I've added NAT as a routing protocol, and set the one on in the VPN address pool as private, and the other as public - but it still won't NAT connections when I add a route through the VPN server's IP on the client side (route add SomeInternetIp IpOfPrivateInterfaceOnServer). I know I can reach the server's private interface (which happens to be 10.2.2.1) with remote desktop client, so I can't think of any issues with the VPN.

  • Setup Linksys 3200 remote access

    - by Greg
    I'm trying to setup remote access for my linksys 3200 so that I can configure it through the WAN port. I have turned on remote access, however when I try to connect I get a 404 error. The settings I have are: When I try to access xxx.xxx.xxx.xxx:9999 I just get a 404 error. I have allowed RDP access to a computer behind the router and this works fine on the same IP address. Any idea's on what else I have to do to allow remote management access? UPDATE: I tried changing the port to 80 and it works. Change it back to any other number and it doesn't work. Modem is setup with a DMZ to the router's IP. Why does it only work on port 80? BTW I can't use port 80 because there is a website hosted behind the router.
