  • Why doesn't jquery validation plugin's remote attribute work for me?

    - by Pandiya Chendur
    I use jquery validation plugin and the remote attribute works with emailId but not with mobileNo? var validator = $("#addform").validate({ rules: { Name: "required", MobileNo: { required: true, minlength: 10, remote: '<%=Url.Action("getClientMobNo", "Clients") %>' }, Address: "required" }, messages: { Name: "please provide a client name", MobileNo: { required: "Please provide a mobile phone no", rangelength: jQuery.format("Enter at least {0} characters"), remote: jQuery.format("This MobileNo is already in use") }, Address: "please provide client address" }, A null value is passed to my controller action.. Any suggestion... public JsonResult getClientMobNo(string mobno) { JsonResult result = new JsonResult(); string status = clirep.getClientMobNo(Convert.ToInt64(mobno)); if (status == "Mobile No already exists") { result.Data = false; } else { result.Data = true; } return result; }

  • "Host usb device connections disabled" in VMware???

    - by ZlateWay
    I installed Linux, Windows XP and Chrome OS in VMware Workstation 7 and in every OS the USB host doesn't work. When I start some of the Operative Systems this message shows up: "host usb device connections disabled" and under that : "The connection to the VMware USB Arbitration Service was unsuccessful. Please check the status of this service in the Microsoft Management Console." So what to do? What do I need to install to make the usb host work? BTW I use Windows 7 as a host OS. Thanks

  • Cannot delete unknown (orphaned) vm from ESX host inventory

    - by Eire09
    Hi, I'm having problems delete an unknown (orphaned) VM from an ESX 3.5 host. When I attempt to right click the VM I get the following error "Object reference not set to an instance of an object". Steps taken so far. 1. Removed the host from the cluster 2. Removed the host from vCenter 3. Rebooted the host 4. Edited the file vmInventory.xml & cleared the file 5. Restarted services - mgmt-vmware restart Can anyone think of anything else that I can do to resolve this issue? Thanks guys.

  • VMWare server host agent service won't start

    - by Bimo Arioseno
    I'm using VMWare Server 2.0 on Windows Server 2003 R2. Sometimes after restarting the host machine, the VMWare host agent service won't start due to an error. This is the error messages from Event Viewer: [Service control manager] Timeout (30000 milliseconds) waiting for the VMware Host Agent service to connect. [Service control manager] The VMware Host Agent service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. I've set the service to automatically restart after subsequent failure using services.msc (using a 10 min. delay), but it still won't start. Only starting the service manually seems to work. Has anyone experienced this before? What workarounds or fixes are there?

  • Business Owners - What Remote Desktop Solution Do You Use To Service Your Clients PCs?

    - by Sootah
    Howdy fellow computer geeks, I am the owner of a local computer repair business that primarily services its clients on-site. On the occasions that we do service the machines in the office we generally have one of our techs pick the computer up while they are out and about and bring it back with them. Only rarely will we require the customer to bring us the computer themselves. In order to reduce costs, be much more efficient, and potentially expand our market far beyond what would be feasible with travel required; I am looking at ways that we can service our clients remotely whenever possible. What we're in need of is a solid remote desktop application that will be incredibly easy for our customers to connect to, as well as be robust enough that we don't need the client babysitting the computer during the entire repair. Ideally I would like to use a web-based solution so that we don't have to walk the customers through installing, connecting, and configuring it over the phone. This would be unacceptable because of the level of service they are used to. Effectively we'd want them to be able to just go to a URL, enter a PIN or something, and then they are connected and ready to rumble. (Obviously the option to just email them a link that'd do all this for them would be what we'd be aiming for) Along with the ease of use factor, we would need the product to not require any further intervention on the part of the client after we have connected. Nobody is going to be happy if we have to call them every 15 minutes so they can reconnect to us every time we reboot - so auto-reconnect is an absolute must. The only product I know of right now that does any of this is LogMeIn Rescue. It allows unattended access, the applet is lightweight and installs quickly, and the customer can either enter a PIN on the site or just click a link emailed to them in order to connect. The only real downside I see to LogMeIn Rescue is that it's $120.00/month per technician. While we'd ultimately end up saving far more than that per month just in fuel costs alone, I'd like to explore any other options out there that I may not have come across. So - Are there any equally good products out there? If so what are they, why do you recommend them, how have you been utilizing them yourself, and what do they cost? Thanks in advance for your help! -Sootah

  • How to setup Hadoop cluster so that it accepts mapreduce jobs from remote computers?

    - by drasto
    There is a computer I use for Hadoop map/reduce testing. This computer runs 4 Linux virtual machines (using Oracle virtual box). Each of them has Cloudera with Hadoop (distribution c3u4) installed and serves as a node of Hadoop cluster. One of those 4 nodes is master node running namenode and jobtracker, others are slave nodes. Normally I use this cluster from local network for testing. However when I try to access it from another network I cannot send any jobs to it. The computer running Hadoop cluster has public IP and can be reached over internet for another services. For example I am able to get HDFS (namenode) administration site and map/reduce (jobtracker) administration site (on ports 50070 and 50030 respectively) from remote network. Also it is possible to use Hue. Ports 8020 and 8021 are both allowed. What is blocking my map/reduce job submits from reaching the cluster? Is there some setting that I must change first in order to be able to submit map/reduce jobs remotely? Here is my mapred-site.xml file: <configuration> <property> <name>mapred.job.tracker</name> <value>master:8021</value> </property> <!-- Enable Hue plugins --> <property> <name>mapred.jobtracker.plugins</name> <value>org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin</value> <description>Comma-separated list of jobtracker plug-ins to be activated. </description> </property> <property> <name>jobtracker.thrift.address</name> <value>0.0.0.0:9290</value> </property> </configuration> And this is in /etc/hosts file: 192.168.1.15 master 192.168.1.14 slave1 192.168.1.13 slave2 192.168.1.9 slave3

  • lighttpd virtual host config

    - by muncherelli
    Trying to get these two vhosts set up correctly. I have two sites on this domain that i'm hosting: www.example.com/example.com and test.example.com. How do I get both of these to work in my vhost definitions? I have: $HTTP["host"] == "test.example.com" { and $HTTP["host"] =~ "(^|.)example.com$" { (I think this is for *.example.com) It always goes to the second one, even if I am trying to go to test.example.com. I need to be able to host www.example.com/example.com and test.example.com

  • bind9 "error sending response: host unreachable"

    - by wolfgangsz
    of course), I have a number of DNS servers, all running bind9 (9.5.1, to be specific) under fedora. 4 of them are slaves, fed by a common master for our public DNS. These are all located on the public gateways of our various offices. One of them has tons of messages in its log files similar to these: Jul 21 17:26:18 gateway named[3487]: client 10.171.3.8#52500: view internal: error sending response: host unreachable I wonder where that comes from. The firewall is open on port 53 between the two machines (10.171.3.8 is an internal DNS server located on a Windows Domain Controller). The internal domains do NOT list the gateway as a name server (so there should not be any attempts of replicating the domains), and the gateway does not handle any internal DNS. The clients in these messages vary between the two domain controllers on the internal network and a third internal name server (running bind9 on debian in a different segment of the network). Any pointers are highly welcome. In response to the first reply: The issue with this really is that tcpdump doesn't show any problems. Here is an extract from "tcpdump -i any port 53" 09:13:38.283308 IP valine.aminocom.com.61815 ns-pri.ripe.net.domain: 14075 PTR? 166.225.58.95.in-addr.arpa. (44) 09:13:42.007410 IP gateway-eng.aminocom.com.37047 alanine.aminocom.com.domain: 35410+ PTR? 12.3.172.10.in-addr.arpa. (42) At the same time, the DNS log shows: Jul 22 09:13:38 gateway named[3487]: client 10.171.3.6#61300: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.172.3.12#56230: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.171.3.8#55221: view internal: error sending response: host unreachable Jul 22 09:13:49 gateway named[3487]: client 10.171.3.8#51342: view internal: error sending response: host unreachable So clearly at 09:13:40 there were two unsuccessful attempts to connect to internal machines (10.172.3.12 and 10.171.3.8, both are DNS servers), but nothing in the tcpdump output.

  • Strict security and virtual host isolation with Nginx?

    - by Hach-Que
    I currently have an Apache web server set up under which each virtual host is isolated using HTTPD-ITK and the AppArmor module. Each virtual host's workers are setuid/setgid by the server and are then placed in an AppArmor profile. I'm looking to use Nginx but I can't find any documentation on setting it up so that rather than the worker processes being shared between all virtual hosts, worker processes are per virtual host (and thus can be setuid / setgid). Is there any way to do this under Nginx?

  • Guests can't access KVM host server by name although nslookup and dig returns correct record

    - by user190196
    So I have a KVM host that also runs an apache server with some yum repos. The VM guests are connected to the default virtual network, which is configured to offer DHCP and forwarding with NAT on virbr0 (192.168.12.1). The guests can successfully access the yum repos on the host by IP address, so for example curl 192.168.122.1/repo1 returns the content without problems. But I'd like to have the guests be able to reach the web server on the host by name rather IP address. I added the desired name record to the host's /etc/hosts file and libvirt's dnsmasq service seems to be serving that correctly to the guests since nslookup and dig successfully resolve the name on the guests: [root@localhost ~]# nslookup repo Server: 192.168.122.1 Address: 192.168.122.1#53 Name: repo Address: 192.168.122.1 [root@localhost ~]# dig repo ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.el6 <<>> repo ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55938 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;repo.

  • Unknown Host Error, is this a registrar problem or a host problem?

    - by jerrygarciuh
    Hi guys, I am dealing with a barrel of weasels on this one. Ad agency registered the domain in mid-August with Network Solutions. 72 hours ago I updated the DNS to point to a host provided by an associate of the client whose credentials are dubious. The DNS servers are at NETSONIC.NET (NS1 and NS2) and respond to ping no problem. I can FTP to the server using its IP but the name is no go. The name is also no go for tracert and ping: tracert voodoobbqfranchise.com Unable to resolve target system name voodoobbqfranchise.com. ping voodoobbqfranchise.com ping: unknown host voodoobbqfranchise.com I called NetSol and of course their tier one guy swears it must be the host but I insist that an unknown host must be a NetSol issue. Otherwise we'd get somethng like an httpd_conf error after being routed to the Netsonic server. Am I right? Is this an issue at the registrar? TIA JG

  • Remote hosts accessing AD's registry

    - by smitty user
    I have a situation here. I have an intrusion detection system and it constantly alerts me that a remote host is accessing our AD's registry remotely. Our remote hosts are mainly Windows XP and our ADs are W2K8. The remote hosts access them over SMB port 445 Is it normal for Windows hosts to access AD's remote registry? My colleagues confirmed with me that both host and AD is clean from virus with endpoint protection enabled. Thanks.

  • KMS host setup: Windows 8 and Server 2012 support

    - by Chadddada
    As our client computer team is in the process of creating some Windows 8 images I have been charged with the setup of the KMS host to support this OS. I do currently run a 2003 KMS host that serves Office 2010, Server 2008, and Windows 7. However from looking at this Technet page it would seem that I cannot install Windows 8 or Server 2012 KMS host services on Server 2003. Am I reading that correctly?

  • How to configure cookieless virtual host in Apache2?

    - by xzyfer
    We run over a hundred web applications (growing daily) on a LAMP stack using Apache2 on Ubuntu 10.04. We've would like all requests to static content to be cookieless. We host applications on many different domains, a majority of which as SaSS applications. Many of the domains host instances of the applications on sub domains, ie. myapp.example.com, myapp2.example.com myapp.otherexample.com etc.. At the moment all static content is server relative to the (sub)domain requesting it. As far as I understand the process, I would need to setup a new domain, eg. staticexample.com. In this case is special configuration in the virtual host for this domain required to ensure no cookies are served? Also, would it be possible to instead use static.example.com? In this case what configurations would I need in my virtual host for this subdomain to ensure no cookies are served?

  • VMpalyer: host keyboard layout on guest?

    - by TheDeeno
    I use the dvorak keyboard layout on windows 7. Also, I have a bunch of custom keys mapped using autohotkey. I'm curious, is it possible to have the guest only receive the keyboard events produced by the host? I don't really know how the host communicates keyboard strokes to guests so I don't know how to enable this or if it's possible. Thoughts? Host OS: Win7 x64 Guest: Unbuntu 9.10 x64

  • Two Ubuntu Instances (Guest) networking with XP (Host) in virtual box v3.1.4

    - by EnthuCrazy
    So here is my current objective: I need to create two guest instances of Ubuntu Desktop 9.10 in VirtualBox on a WindowsXP host. (This is needed for communications later on.) (this step is almost done) I need to establish networking between all three OS's, the host and two guests (Guest1 - Host - Guest2). I know that generally, to establish networking between Windows host and Ubuntu guest, we set up a bridge connection. But here there are two guests, and primarily I need networking between the two guests (Ubuntu to Ubuntu). So will there need to be a change in tap0 and tap1 interfaces when we set up a bridge, or is there a better way to implement this? Please explain the procedure.

  • VirtualBox: Can't get Bridged Networking to work (Win7 host)

    - by MikeTheTall
    I'm trying to set up a virtual LAMP server, including sharing files between the guest OS (Ubuntu Server) and the host OS (Windows 7) using samba. I think my problem is that I can't get Bridged (or Host-Only) networking to work in VirtualBox. I can boot the Linux VM just fine with NAT, but then can't access any services on it directly (except after port-forwarding port 80)(my understanding is that port-forwarding works because I'm not running a web server on the host OS, and therefore it can forward traffic to the unused port 80). I don't think that port-forwarding samba traffic (from the host to the guest) will work since I think that the host OS is using those ports. When I turn off NAT and turn bridged networking on I get an error. The VM fails to boot, with a dialog popping up (title: VirtualBox - Error) that says "Failed to open a session for the virtual machine UbuntuServer. Configuration error: Failed to get MAC address (VERR_CFGM_VALUE_NOT_FOUND). I'm hoping that once this is resolved then samba will work ok :) Any advice on this would be great (how to fix it would be wonderful, next steps for troubleshooting would be great, too :) )

  • "No route to host" with ssl but not with telnet

    - by Clemens Bergmann
    I have a strange problem with connecting to a https site from one of my servers. When I type: telnet puppet 8140 I am presented with a standard telnet console and can talk to the Server as always: Connected to athena.hidden.tld. Escape character is '^]'. GET / HTTP/1.1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>400 Bad Request</title> </head><body> <h1>Bad Request</h1> <p>Your browser sent a request that this server could not understand.<br /> Reason: You're speaking plain HTTP to an SSL-enabled server port.<br /> Instead use the HTTPS scheme to access this URL, please.<br /> <blockquote>Hint: <a href="https://athena.hidden.tld:8140/"><b>https://athena.hidden.tld:8140/</b></a></blockquote></p> <hr> <address>Apache/2.2.16 (Debian) Server at athena.hidden.tld Port 8140</address> </body></html> Connection closed by foreign host. But when I try to connect to the same host and port with ssl: openssl s_client -connect puppet:8140 It is not working connect: No route to host connect:errno=113 I am confused. At first it sounded like a firewall problem but this could not be, could it? Because this would also prevent the telnet connection. As Firewall I am using ferm on both servers. The systems are debian squeeze vm-boxes. [edit 1] Even when I try to connect directly with the IP address: openssl s_client -connect 198.51.100.1:8140 #address exchanged connect: No route to host connect:errno=113 Bringing down the firewalls on both hosts with service ferm stop is also not helping. But when I do openssl s_client -connect localhost:8140 on the server machine it is connecting fine. [edit 2] if I connect to the IP with telnet it also is not working. telnet 198.51.100.1 8140 Trying 198.51.100.1... telnet: Unable to connect to remote host: No route to host The confusion might come from IPv6. I have IPv6 on all my hosts. It seems that telnet uses IPv6 by default and this works. For example: telnet -6 puppet 8140 works but telnet -4 puppet 8140 does not work. So there seems to be a problem with the IPv4 route. openssl seems to only (or by default) use IPv4 and therefore fails but telnet uses IPv6 and succeeds.

  • Network Misconfiguration when adding first host to new vSphere cluster

    - by dunxd
    I am building a new vSphere cluster from scratch. I have installed ESXi on the first host, and built a vCenter server on a VM residing on that host (storage is on the local hard drive, although we have iSCSI targets which I can reach from the host). The cluster is configured for HA. When I try and add the host to the cluster, I get an error at the point where HA is configured - Cannot complete the . I have stripped the network configuration of the host down to the most basic - a single NIC attached to a single vSwitch - this is running the VMKernel Port on VLAN 8 - that is our Management VLAN. The vCenter server will have a network address on this VLAN, so I also set the initial Virtual Machine Port Group to this VLAN, and connected the vCenter server NIC to this port group. I understand I can't connect the vCenter server to the VMkernel port group, but shouldn't I be able to connect the vCenter server to a Port Group in the same VLAN? If not, do I need to create a VLAN specifically for VMKernel Port Group? I plan to set up another port group for vMotion with a dedicated and isolated VLAN (i.e. VLAN isn't routed) so this wouldn't allow vCenter to communicate. Does anyone have any suggestions, or other ideas for what might be causing the problem. I've read through the documentation, but it isn't giving me any pointers, and the error message isn't helping me beyond telling me something is wrong with my network config.

  • Access Bind9 DNS in Virtualbox on Host

    - by Philipp Melab
    I've set up a Ubuntu 10.04 Virtual Box with a Bind9 DNS server. The Box has a NAT Network connection for internet access and a host-only adapter for static ip connections from the host (OSX Lion). Thats the only way i managed to get internet and static ip inside the box, guess there is a better one ... The DNS works fine from inside the virtualbox, but not from the host. The http and ftp on the guest system is accessible via both addresses, so connection between host and guest are fine i guess. I tried to add both IP's as name servers. I'm completely new to Bind9 and DNS configuration. Anybody has a hint for me whats wrong? Or how i have to configure the DNS server?
