  • FluentValidation + s#arp

    - by csetzkorn
    Hi, Did someone implement something like this: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ in s#arp? Thanks. Christian PS: Hi, I have made a start in using FluentValidation in S#arp. I have implemented a Validator factory: public class ResolveType { private static IWindsorContainer _windsorContainer; public static void Initialize(IWindsorContainer windsorContainer) { _windsorContainer = windsorContainer; } public static object Of(Type type) { return _windsorContainer.Resolve(type); } } public class CastleWindsorValidatorFactory : ValidatorFactoryBase { public override IValidator CreateInstance(Type validatorType) { return ResolveType.Of(validatorType) as IValidator; } } I think I will use services which can be used by the controllers etc.: public class UserValidator : AbstractValidator { private readonly IUserRepository UserRepository; public UserValidator(IUserRepository UserRepository) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; RuleFor(user => user.Email).NotEmpty(); RuleFor(user => user.FirstName).NotEmpty(); RuleFor(user => user.LastName).NotEmpty(); } } public interface IUserService { User CreateUser(User User); } public class UserService : IUserService { private readonly IUserRepository UserRepository; private readonly UserValidator UserValidator; public UserService ( IUserRepository UserRepository ) { Check.Require(UserRepository != null, "UserRepository may not be null"); this.UserRepository = UserRepository; this.UserValidator = new UserValidator(UserRepository); } public User CreateUser(User User) { UserValidator.Validate(User); ... } } Instead of putting concrete validators in the service, I would like to use the above factory somehow. Where do I register it and how in s#arp (Global.asax)? I believe s#arp is geared towards the nhibernator validator. How do I deregister it? Thanks. Best wishes, Christian

  • Programmatic use of ARP

    - by sizzzzlerz
    I have a need for some C or C++ code, compilable under Linux, to be able to take a list of IP addresses of some arbitrary number of remote hosts machines and obtain a ethernet MAC address for each one. These host machines may be on the same subnet or they could be on a different subnet behind a router. Its OK if the MAC address of some or all of the remote hosts is the address of the interface on the router. Ultimately, I want to hand off the IP address and MAC address to an FPGA who will use these pieces of information to format and send UDP/IP packets over ethernet to the hosts. Obviously, the FPGA will also be given its own MAC address and IP address to fill in the source MAC and source IP addresses in the packets. Is there some code I can be pointed to that can create and broadcast ARP packets to these remote machines and receive back the ARP response packets such that the destination MAC addresses can be extracted?

  • How to setup a static multicast ARP entry with Cisco SG300?

    - by Fredrik Hedberg
    We're running a Microsoft NLB cluster in multicast mode as a loadbalancer. Using our old Cisco IOS switches we propagate access to the cluster to our branches using a static ARP entry in the core router: arp 10.20.1.226 03bf.0a14.01e2 ARPA But how does one solve this using non-IOS based Cisco hardware such as the SG300 series? Adding a static ARP entry results in an error message telling the user that the hardware address needs to be a valid unicast MAC address.

  • how can I stop my sonicwall TZ-210 (SonicOS Enhanced 5.5.1.0-5o) from responding to arp queries on the wan subnet?

    - by IsaacB
    My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway. How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately. What can I do? Any suggestions?

  • What happens when ARP Request comes from a different subnet?

    - by gsinha
    What will happen when an ARP Request packet is sent from router1 to router2 in the following two cases? Will an ARP Reply be generated or the ARP Request packet be dropped? [router1]Intf1(20.0.0.1/24) ======== (40.0.0.1/24)Intf2[router2] [router1]Intf1(20.0.0.1/24) ======== (20.0.0.2/8) Intf2[router2] The topology above have a port "Intf1" on router "router1" connected a port "Intf2" on another router "router2" via a direct link(eg, a 1 Gbps cable).

  • Is there a way to define a rule on a bridge that will return reply for ARP request

    - by user1495181
    client (IP = 1.1.1.1) - bridge (brctl) - server (IP = 2.2.2.2) (all machine are Ubuntu). The client block arp request. (there are multiple clients ) I need to define a rule on the bridge machine that will return the client MAC when it get ARP request for IP 1.1.1.1.

  • Using netlink to obtain arp entries only returns stale entries

    - by Ben
    I'm currently trying to retrieve reachable neighbors from the arp table in a user space program written in c. I've looked through the source code to the "ip neigh" command (ipneigh.c) and it appears that I should use the flag NUD_REACHABLE. struct { struct nlmsghdr n; struct ndmsg r; } req; memset(&req, 0, sizeof(req)); req.n.nlmsg_len = NLMSG_LENGTH(sizeof(struct ndmsg)); req.n.nlmsg_flags = NLM_F_REQUEST | NLM_F_ROOT; req.n.nlmsg_type = RTM_GETNEIGH; req.r.ndm_state = NUD_REACHABLE; However, when I look at the data returned from the kernel, I only have stale entries. In fact, no matter what I put for req.r.ndm_state it seems to return only entries marked as stale by ip neigh. The remainder of my code is modeled after this example: http://linux-hacks.blogspot.com/2009/01/sample-code-to-learn-netlink.html

  • Solaris 10 invalid ARP requests from 0.0.0.0?

    - by JWD
    The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). xxxx:xxxx:xxxx/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else?

  • Solaris 10 invalid ARP requests from 0.0.0.0? Link up/down every hour or 2

    - by JWD
    The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). [mymacaddress]/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) It's being logged every hour. I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. There are some tunable SCTP parameters but it's not something I'm familiar with. Do I have to add changes to /etc/system? Looks like sctp_heartbeat_interval might be what I need to change? If it makes any difference, I have a few solaris zones running on this server, each with their own IP address on a virtual interface. eth0:0, eth0:1, etc. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else? Update: This was happening more frequently but now it seems to be happening roughly every hour or every two hours. It's not consistent. I tried setting setting the link speed and duplex to match the switch port and that seemed to make it stop happening for a few hours but then it started again.

  • Is there any way to ARP ping on Windows?

    - by e-t172
    On Linux and other systems, there is an utility called arping which can be used to send ARP requests ("pings") and show the answers, much like the "ping" utility but using ARP instead of ICMP. Is there any way to do the same on Windows? (I use Windows 7)

  • How to stop my VPS from picking up ARP reqs it is not supposed to?

    - by Charles Stewart
    Machine: Xen-3.0 image running stable Debian Linux 2.6.18, pretty vanilla. My VPS provider asks me to deal with some trouble my image is causing, namely handling IP addresses it is not supposed to: The problem is that your server seems to be configured to use IPs that have not been appointed to you. Your server responds to ARP requests for the IPs 81.171.111.219 and 81.171.111.218. But you are not allowed to use those. Not explicitly, as far as I can tell! At least, nothing under /etc or /var/tmp mentions these IP addresses. But arp -v says something I can't make sense of: Address HWtype HWaddress Flags Mask Iface 81.171.111.1 ether 00:0C:DB:E3:80:00 C eth0 Entries: 1 Skipped: 0 Found: 1 What is it listening to? The possibilities seem to be: It's not my fault: my VPS providers have overlooked something. What might that be? 81.171.111.1 means I'm happy listening in on ARP requests that I shouldn't be: how do I change this? In any case, what does this mean? I'm looking in completely the wrong place for information on what my image is doing. Where should I be looking?

  • Failure to obtain IP with ARP over Wi-Fi with personal Wi-Fi router in client mode

    - by axk
    I'm trying to connect a Samsung TV to the Internet using a TL-MR3020 personal wireless router in client mode. The TV fails to connect to the network. It sees the ethernet cable connected though. Here's my network topology: Here's what I've captured with Wireshark filtering for ARP (eth.type == 0x0806): It appears the TV fails to get the IP of the gateway (DSL modem/router) for some reason. One thing I've noticed is that the source MAC for the ARP requests coming from the TV is the MAC of the Portable wireless router (that is cd:89:00), not the TV itself and the modem sends the responses to that MAC (I'm not an expert and don't know if its okay or it may make the TV fail to get the requested IP). Also I'm able to ping the TV from the DSL router (through the telnet interface) and the router has an entry in its MAC table for the TV's IP with the Portable wireless router's MAC (that is cd:89:00). If I'm able to ping the TV I suppose it should know the router's MAC to respond to the ping, but then why these continuous ARP requests... I've also tried to connect my desktop trough this Portable wireless router the same way I'm trying to connect the TV and it works fine, I can set the DSL Modem's IP as the default gateway on the desktop's NIC and connect to the Internet. The TV can connect to the Internet when connected to the DSL Router with a wired connection. Any suggestions on what may be the cause of the problem / how to further debug it are welcome. Thanks!

  • Windows Vista DHCP bug, arp authorize, isc dhcp, workaround

    - by jinanwow
    I am trying to find a workaround for the Windows Vista Force Broadcast bug with ISC DHCP and a Cisco Router. The problem is not windows vista trying to obtain an IP address from us that works fine (with or without the flag enabled). THe problem is we are using a cisco router and the command 'arp authorized' to prevent users from using static IP addresses on the network. The problem is, if Windows Vista sets the boot flag to true the command 'arp authorized' will not work, as it looks for the IP address and destination MAC address in the DHCP Offer Packet to add it to its arp table. The machine will DHCP just fine, but since the ARP table is not aware of the machine, it is unable to access the internet. If I disable the broadcast flag in vista, the next time it DHCPs an arp entry gets created since the DHCP Offer is unicast instead of broadcast. The thing is, we can not tell 500 to 1000 people to edit their registry, so we need a workaround for this issue. I have not had much success in finding a workaround. The question is, is there a way to force or trick ISC DHCP into unicasting a responce back to the user. Either on the Cisco Side, ISC DHCP side or intercepting and rewriting the DHCP Discover UDP packet to turn off the flag before it reaches ISC DHCP?

  • Cannot ping host stale ARP cache?

    - by gkchicago
    I am having a strange issue with a Debian (Lenny/Linux 2.6.26-2-amd64) that has been driving me nuts. On some machines within my network I can ping the host in question just fine, other times I have to manually hard-code the ARP ethernet address for the IP in order to establish connectivity. I've finally worked it down to somehow involving ARP. I just found how to fix it in a way that made it work but I'm looking for help explaining this issue and also I don't trust my fix to be permanent.. My thought process has been the following but I just can't make any sense out of it: Could it be the card? (Intel 82555 rev 4) Could it be because there are two network cards? (Default route is eth0) Could it be because of the network aliases? Lenny? AMD x86_64? Argh..

  • Arp tries on various *nix based systems.

    - by salparadise
    Does anyone know what determines the amount of arp tries a router will make? I have different behaviors with two devices, if I try to traceroute to a non-existent host on a subnet that belongs to an interface on the router, a Linux box will try to arp 3 times and then return a host un-reacheable icmp message. Junos will continuosly try to arp and not return anything. Is there a sysctl value that determines this or anything at all.

  • Why host and vmware guests fail to get MAC of each other?

    - by Georgiy Nemtsov
    I have Windows 7 64bit host running VmWare Workstation 8 with two CentOS 6.3 guests. All guests adaptors are bridged with statically assigned ip's. Connectivity bitween host and guests was fine for many days running this setup. And today while I was working suddenly host and guests became unreachable for each other. While both host and guests could connect to internet and connect to other mashines in my networks. On guests arp -a showed for host ip address: ? (192.168.1.3) <incomlete> on eth0 On host arp -a showed for guests ip 192.168.1.19 00-00-00-00-00-00 192.168.1.20 00-00-00-00-00-00 All other arp records was OK. Deleting arp-caches didn't help neither on guests nor on host. After that I disabled and reenabled network adaptor on my Windows 7 host. And the problem was gone. arp -a now shows correct MACs on all instances. As I suppose the issue was about expiry of arp cache. For some reason host and guests couldn't get their MACs. Hope somebody knows what it is all about? I am preparing guests to work in production and don't want to face such problems in future! Also I was supprised while investigating this issue from another mashine that could connect both on guests and host. On that mashine arp -a showed same MAC for host and two guests.
