• Tecra A10 with wrong source IP address ping responses

  Hello!

  I have problems with my network connection.

  After installing Win7 pro answers tecra A10 ping on the lan with 192.168.0.239 port, but he 192.168.211.36 the DHCP server.
  In Wireshark on tecra A10 I don't see demand for IGMP but no answer.

  On the other PC the answer comes a false IP (and of course a wrong MAC).
  If I disconnect the lan cable a stop responses.
  If I boot in Linux, everything's fine.

  So what software changes IP address?
  I see no answer in wireshark, I think it might be something around the network card.
  Internet is OK, but I can't do any remote.

  Someone at - it an idea?

  If your problem is the remote control only, right?

  If I understand right you don t use original Toshiba recovery image so no one here Don t know exactly what have you installed and you do exactly.
  If your LAN/WLAN card working properly and you can connect to your router, this proves that there is no hardware problem.

  Have you tried the same thing with the original preinstalled recovery image?

• No Ping response from Site to Site connection between 876 of Cisco and CheckPoint Firewall

  Hello!

  We try to create a Site-to-Site - connection IPSec between a Cisco 876 (local site) and a control-firewall station (remote site). Cisco 876 is not directly connected to the internet, but it is behind a router ADSL with port-forwarding, redirection of ports 500 and 4500. The configuration of the Cisco 876 running is attached to this thread. Unfortunately, I get no results when debugging the connection with the command "debug crypto isakmp" and "debug crypto ipsec".

  From the point of view of Checkpoint firewall the connection seems to be implemented, but there is no response from ping.

  The server in the local site to be achieved since the network behind the firewall Checkpoint has a routing entry "PEI route add [inside the ip-net Remote] 255.255.255.0 [inside the premises of intellectual property]" (see also annex current config name ip addresses).

  Establishing a VPN Cisco Client connection to the same router Cisco 876 works very well.

  Any help would be much appreciated!

  Hi Jakob,

  Add my two cents here.

  You should always verify that the following ports and Protocol are open:

  1 - UDP port 500--> ISAKMP

  2 - UDP port 4500--> NAT - T

  3-protocol 50---> ESP

  A LAN-to-LAN tunnel will never establish a TCP session, but it could use NAT - T (if behind a NAT). Remember that a single translation isn't a port forwarding, a LAN-to-LAN tunnel is not good unless you have a one-to-one translation of the NATted device, which I think, in your case the router is working.

  HTH.

  Portu.

• Duplicated in NSX Ping responses

  Anyone who knows the resons of ping replies duplicated in the environment of the NSX. Please check the attached screenshot

  I guess you see this as part of hands-on Labs?

  Guests in the labs are virtual hosts actually it is to say it is a nested virtual environment.  Its a known issue, you can see an icmp answer duplicate in this environment.  Don't worry, it's not in a real environment of the NSX :-)

• Inconsistent response from ping...

  Hello:

  I have ESX 3.0.1 and recently built 3.5 after I moved my VM to new ESX host they are running very very slow (they run normal if I brought back them to old ESX 3.0.1).)  I noticed that they have a problem with network (when both my NIC does not 'connected' they run much faster). I checked all network settings and they seem to be correct.  Also, I noticed that I have my VM incompatible ping response (it's the evolution of the 3500ms and 50ms), however, when I ping service console (it's on the same vSwitch) I always 50ms (that's good enough for me, because I'm very far from my servers).

  Do you have a some see this issue before?

  Thank you

• Ping

  How do I detect if I have or now crazy, who and source a ping?

  Best regards

  Much depends on the configuration of your network.  If you use a router NAT Européene (or a combination of modem/router), then the ping (ICMP) packets probably stop the router and not pass on your computer.  Some routers have settings configuration as agglomerates, they will respond to a ping.  Therefore, any monitoring pings must be generated in your router.

  If you don't have a router and are directly connected to the modem or internet, then you probably need a firewall product controlling or record the pings.  The more information you will get will be the IP address that the ping response goes back to, so if you want a physical location of the IP address, you will need to do additional research.

  Hello

  ·        Were you able to make a connection between two computers before?

  ·        What is the exact error message that you encounter when you try to access the computer?

  Method 1:

  I suggest you check in SafeMode with network you are able to access computers. Follow the steps mentioned below.

  a. restart the computer and keep tapping F8 until you reach the start menu.

  b. Select safe mode with networking from the list and press ENTER.

  c. check to see if the problem persists.

  Method 2:

  I suggest to disable the security software installed on the system and check if the problem is resolved.

  Note: Once done the test, I suggest you to restart the system security software and check if the problem is resolved.

• Vista do not you answer ping - file sharing also stopped working

  Greetings!
  I have problems with my windows vista computer. It can access the internet, load the pages and other servers, ping, but he stopped answering the ping requests and file sharing has stopped working (other computers cannot access its actions).
  -J' have already disabled the two firewalls (both windows and f-secure).
  -If I run wireshark, I can see the Ping ICMP requests (as they arrive at the machine), but ignores them (no ICMP response).
  -When I try to browse the computer from another windows (windows 7), he sees the computer (they are on the same workgroup), but it is impossible to browse. Try to access it from a mac also fails.
  -J' tried to use direct ip address instead of the netbios name, with no luck (access to \\192.168.1.101, for example).
  -Of course, I tried already reboot my router, computers, etc.
  -sfc/scannow detected a few corrupted files (but says he fixed them). But it did not help.
  -J' thought that it might be a problem with windows system files, so I uninstalled SP2 and then reinstalled with no luck at all.
  -J' already tried to reset the tcp ip (netsh int ip reset) stack but also had no success.
  -I'm clean of viruses; already run 3 different AVs (including boot from rescue CD to detect rootkits) and nothing came.
  I'm almost reinstall my whole windows, but I'm afraid even if it cannot solve the problem and having to install from scratch and reinstall * all * my new aplications will be a last operation of the station. Clues as to what I could do? Is there a way manually reset/reinstall only the sectors/services windows network?
  Thank you for your time,
  Gustavo

  Greetings!

  Just the answer I finally had myself on this issue.
  The problem was a malware removal tool called Combofix. I had an infection and several tools to clean, one of which was this tool. I ignored the warning to leave unattended a guru of malware removal, and I just let it do its job (I know, I was wrong... but desperate times require desperate measures). Apparently, he finished and my system was working fine... but not the file share and ping responses.
  Finally, there is a way to reverse the changes made by the latter:
  • Go to C:\WINDOWS\ERDNT\subs\erdnt.exe, double-click erdnt.exe , and then restart the machine.
  • If this does not work, then navigate to C:\WINDOWS\ERDNT\Hiv-backup\erdnt.exe, double-click erdnt.exe and restart the machine.
  By doing this, the reverse tool changes to the system registry and these two services that weren't previously returned to work normally.
  The Trojan horse itself not worried anymore, because I ran Combofix all as precautionary measure, since I had already deleted the Trojan horse itself (ZeroAccess, by the way).
  That being said, I would think twice before getting a Dell computer next time... The version of Vista that comes with it only allows a 'Clean Install' and not 'upgrade install', which seriously complicates to reinstall the system failure (since I have to reinstall * everything *). I wonder if other versions of windows to PC manufacturers have the same limitations...

• SG200 - 26 [FW - 1.1.2.0]-very high response time: > 1000 ms!

  Hello

  Problem: New SG - 200 26 Smart Switch with the latest Firmware - very high response time 500-800 ms

  We have a router of EdgeMarc 4500 with 10 VPN tunnels at 10 locations of brach. SG-200 26 Smart Switch is connected to 7 servers (Terminal 2, SQL and others), all locations have 50 MB download and download 20 MB of Verizon FiOS Internet service speed.

  Depending on the tool Kulvik, the response time of this switch is around 500ms. At the same time, the response time of the EdgeMarc 4500 router is around 40ms and less.

  We have 60 remote desktop computers connected to our SQL Server database and 40 users of RDP via Remote Desktop. The configuration is the same for 3 years. But we change the switch HP 1800 - 24G of Cisco because of some failures of connection. For connection failures, we first think the old switch from HP, but it looks like problem with router EdgeMarc.

  This response time is normal? I have attached two screenshots of Switch Cisco and response time for the past 24 hours EdgeMarc router according to the tool Kulvik. Any other advice would be greatly appreciated. Thank you.

  Hello Srinath,

  Thank you for your participation in the community of support to small businesses. My name is Nico Muselle of Cisco Sofia HWC.

  The response time of the switch can be considered quite normal. Reason for this is that the switch gives CPU priority to its actual tasks that would be sure to pass, lists of access, VLANs, QoS, multicast, and DHCP snooping etc etc. As a result, the switch itself ping response time does not show in any way the good operation of the switch.

  I invite to try the rattling customers connected to the switch, you should be able to notice that the response time to customers are much lower than the response time of the switch itself.

  I hope that answers your question!

  Best regards

• OEM services for the monitoring of the TNS ping.

  Hello

  I want to create the 12 c OEM service to test ping response TNS. While creating a service we need to specify some parameters of Test in step 3 test of Service.

  and I can't understand what value should be specified for the connection string.

  Please help me on this.

  You can enter the connection string in this format:

  (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST =)(PORT=))) (CONNECT_DATA = (SID =)))

  where:

  : the host where the database

  : the database listening port

  : the SID of the database

  Ex:

  (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST=alpha.oracle.com) (PORT = 1521))) (CONNECT_DATA = (SID = ORCL)))

  Alternatively, you can leave blank the connection string field and enter the appropriate values for the following areas:

  -Host

  -Port

  -SID

• Create array of IP addresses that do not respond to ping

  I am an intermediate Powershell user, but having a little trouble wrapping my head around how to do it.

  I have a powerCLI script that creates a number of virtual machines based on a variable, and I need to take it to the next level of intelligence:

  }

  but the last piece I am trying to understand is the IP address table.  Here's what I want to do with it, see if anyone can help with thoughts on that.

  • Ping (or connect remotely) a range of IP addresses, in this case 10.11.150.10 - 10.11.150.250 and released those who fail a connection to a range of IP.  The goal is to use this to fill in the information of IP address for servers that are being created.

  As a little more description here, maybe this contributes to possible scripting, I'm creating servers with the 3 last even as long as the last octet of the IP address.  Thus, the script will run, find IPS that are open (not ping response) and deploy servers model based on IP addresses.  For example, if 10.11.150.55 is crazy, does not, the script will deploy the server of server055 with the IP address of 10.11.150.55.

  Thanks in advance for the help

  Something like this will provide a table with IP addresses that do not respond.

  $array = 1.20 | % {'$192.168.1 _"}

  $freeIP = $array | %{

  If (!) () Test-Connection - ComputerName $_-count 1 - quiet - ErrorAction SilentlyContinue)) {}

  $_

  }

  }

• VM management host cannot ping gateway or switch

  Hello

  
  We have a server Esx 5.0 with 3 vm on it. When I try to ping the management network of vm for my pc that I do not get an answer too trying to ping from the vmn console I can not ping to the gateway, but I can ping dns. However, I can rdp in vm servers and the ping to the gateway of each server, as well as newspapers in vsphere. We have a system with 2 voip VLAN, the other data and another for voice. Hosts and servers are all on the same cisco switch.

  VM management network

  IP - 192.168.1.6

  Sub - 255.255.255.0

  GW - 192.168.1.1

  DNS - 192.168.1.10

  Cisco switch - 192.168.1.3

  Data Vlan - 192.168.1.1

  Firewall - 192.168.1.2

  PC

  -cannot ping 192.168.1.6

  -can ping everything else

  From the console network management

  -cannot ping 192.168.1.1 a.3 or any pc

  -can ping 192.168.1.10

  It sounds like a switch problem but do not know how to fix it. The switch is a switch of cisco small business pro 8 ports

  Make sure that your routing has L3 to a defined network to get traffic to your host (192.168.1.0/24) network to any network it seeks to achieve. You did not show what the subnet for the PCs are so I'm not sure that the network is.

  Regarding the gateway ping, make sure that the echo ICMP message is enabled by the firewall so that ping responses can go to the host. If you still cannot ping the gateway with that on, there may be a larger problem with your connectivity.

• Cannot ping my virtual machines!

  Hello

  I have install a machine running Windows 2008 R2 server that has 4 network cards. The server is also my domain controller and dns server.

  NIC 1:

  IP = 192.168.0.27

  Subnet = 255.255.255.0

  Gateway = 192.168.0.10 (IP address of my router)

  DNS = 127.0.0.1

  2 NETWORK CARD:

  People with disabilities

  3 NETWORK ADAPTER:

  IP = 192.168.0.28

  Subnet = 255.255.255.0

  Gateway = 192.168.0.10

  DNS = 127.0.0.1

  NETWORK 4 CARD:

  IP = 192.168.0.25

  Subnet = 255.255.255.0

  Gateway = 192.168.0.10

  DNS = 127.0.0.1

  I installed WM player on the server and created 2 VM, also the two Windows 2008 R2 running.

  I want each of my 3 servers (host + 2 vm) to use a separate NETWORK card, so I used vmnetcfg to create 2 virtual networks.

  VMnet3 is filled to NIC 3

  VMnet4 is filled to NIC 4

  Edit vmx file VM1 saying to use VMnet3

  Have edited the VM2 vmx file to say things to use VMnet4 (see below)

  ethernet0. Present = 'TRUE '.
  ethernet0. ConnectionType = "custom".
  ethernet0.VNET = "VMnet4.
  ethernet0.virtualDev = "e1000".
  ethernet0.wakeOnPcktRcv = "FALSE".
  ethernet0. AddressType = 'generated '.
  ethernet0.generatedAddress = "00: 0C: 29:5 C: 85:EA."
  ethernet0.generatedAddressOffset = '0 '.

  When I connect to VM1, I see that it has an IP of 192.168.0.29.

  It can connect to the internet and it can ping the host 192.168.0.27, BUT any other computer (including the host) can ping VM1

  Even when I have connection to VM2, I see that it has an IP of 192.168.0.31.

  It can connect to the internet and it can ping the host 192.168.0.27, BUT any other computer (including the host) can ping VM2

  Any ideas where I'm wrong?

  Concerning
  Martin

  Welcome to the community,

  Did you only allow ICMP in the firewall of the customer. By default, the ping responses are disabled in Windows 2008 R2.

  With regard to your configuration. I suggest you disable TCP/IP on NIC3 and NIC4 and don't leave the active "VMware Bridge Protocol".

• WiFi works not once I close the lid

  Whenever I close the lid of my macbook, and when I open it again the internet connection no longer works. It shows the wifi is connected but I can't access any site or get a ping response. To resolve this problem, I have to turn off wifi and turn it back on. Why is this happening?

  What happens to me all the time, but I thought it was because I have an old router and Macbook ' 09. I'll be interested to hear other answers
