comando tracert

Problem Description:Recently replaced upgraded server, there has been a problem, is that many users can ping and tracert through our site, but when the landing is not normal, occasionally refresh can open, very abnormal.Catch packet found that the user came over the IP can to the server, but the server did not reply.Thanks to Huang's analysis!!!!Here is a summary of some of the solutions found online.===================================================

Function: tracert-parameter IP (or computer name) trace Route (packet) Usage: tracert-d www.baidu.com If you do not add the-D argument, the address will be resolved to host name, so it will be very slow, and then do not convert, the speed is much faster. The other parameters are as follows: Options:-D does not resolve addresses to host names.-h maximum_hops The maximum number of hops for the search tar

ARP (Address Resolution Protocol)View the appropriate MAC address for the IP address.How to use: Arp-a IP Displays the current ARP cache table for all interfaces.Arp attack is to realize ARP spoofing by fake IP address and MAC address, can generate a large amount of ARP traffic in the network to block the network, the attacker can change the IP-MAC entry in the target host ARP cache as long as the persistent ARP response packet is issued, causing network int

Question:I often use the ping command and tracert command to check the status of hosts on the network to see if they are running normally. However, recently, the company's network management has set a policy on routers and servers to completely disable icmp. As we all know, the ping and tracert commands use the icmp protocol. In this case, I cannot use the preceding two commands to check the host status on

. If we use the ping command to test and verify the connectivity from this computer to the host whose IP address is 10.0.0.99, the ARP cache displays the following items: Interface: 10.0.0.1 on interface 0x1 Internet address physical address type 10.0.0.99 00-e0-98-00-7c-dc dynamic In this example, the cache item indicates that the remote host located in 10.0.0.99 is resolved to the Media Access Control Address of 00-e0-98-00-7c-dc, which is allocated in the NIC hardware of the remote co

address of arp-s can be manually entered into the ARP cache. The project remains valid during the computer boot process, or when an error occurs, the manually configured physical address automatically updates the project. Arp-d IP can use this command to manually delete a static project. Now we can use the ipconfig and ping commands to view our network configurations and determine if they are correct. We can use netstat to view the connections established between others and us and find out the

options that can only work on a computer that rents its IP address to the DHCP server. If we enter ipconfig/release, the lease IP addresses of all interfaces will be re-delivered to the DHCP server (return the IP address ). If we enter ipconfig/renew, the local computer will try to contact the DHCP server and lease an IP address. Note that in most cases, the NIC will be assigned the same IP address as previously assigned. If we are using Windows 95/98, we should be more accustomed to using wini
