Network Diagnostics Pinged Remote Host But Did Not Receive Response
Feb 23, 2011
I can connect to the free wireless with no problem on my company laptop. Last night, I was using my personal laptop (as I have been for 2 weeks) on the wireless internet when I suddenly lost connection. In the Network and Sharing center of Windows Vista it shows a connection to the router but an 'X' between the router and the internet. When I run the diagnostic I get "Cannot communicate with primary DNS server (4.2.2.1)" The it says "Network diagnostics pinged the remote host but did not receive a response".

Windows association failed because Windows did not receive any response from the wireless router or access point. This is the message I have just got out of the blue from my laptop. it is showing that there is excellent strength... And I am also on my iPad connected to this connection.

I'm having trouble connecting using this new card i bought. i have installed the latest drivers and i can find networks and the signal strength is good too but when trying to connect after ive entered the passkey i get the message " no network found" or "did not receive response from router" or something along those lines. i can connect with my older card which is a wmp54g but that one shows less signal strength and my connection breaks from time to time (hence the upgrade to wmp600n) on a sidenote, my wmp600n card works perfectly fine under linux but i want it to run in windows (mainly for gaming) Im running windows vista 64 bit and the wmp600n has the latest drivers installed.

I replaced my old wireless router with a Cisco Linksys E4200, running firmware version 1.0.02 build 13 May 24, 2011. About once a minute the router sends an unsolicited DNS message to the IPV4 multicast address 01:00:5e:00:00:fb with a destination IP address of 224.0.0.251. The unsolicited message is a DNS response with source port 32784, transaction ID 0, flags 0x8400 (standard query response, no error), questions 0, answer RRs 2, authority RRs 0 and additional RRs 1. The two answers both relate to the router itself: one has Name Cisco18738.local, type A (host address), class 1 (IN), cache flush true, time to live 1 minute, data length 4, and the address of the router. The other is the reverse of the same address. The additional record is for Cisco18738.local, type NSEC, class IN, cache flush true, time to live 1 minute, data length 5, next domain name Cisco18738.local, RR type A (host address).
When my desktop computer receives these messages it logs an error, for example: "Jun 23 07:39:22 sauterws02 avahi-daemon[1067]: Received response from host 10.146.9.1 with invalid source port 32784 on interface 'eth0.0'" The 10.146.9.1 is the router's IP address. I also see these messages on the wireless link from my laptop.I suppose the E4200 is generating these DNS messages in a misguided attempt to make sure there is no old information about its name. Is there a way to turn them off? If not, is there a way to report this to Cisco as a bug?

I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.

I've been getting the BSOD randomly on the internet and just went through the Dell diagnostics - by component and symptom. Only error I got was for the Network card : Strength Signal test Tested and needs attention. What do I do to investigate this?
Network card: Dell 1525 WLAN Pcle Card (802.11n) with external antenna.
The computer is connected to the router via ethernet cable.
I've talked to Dell tech support and they're convinced it's a software problem but this implies otherwise.

The Lg840g is a tracfone with wifi capability. I get strong wifi signal and connection at home, but receive failure to connect to requested host message when I open the browser. This phone works at wayport wifi, so I assume it's a compatibility problem with the router. Is there a fix? (Router works great with our Acer and Kindle tablets though.)

I have setup an asa 5505 with multiple sub nets (plus license) and a vpn tunnel (ipsec) between this and an other asa on a second branch office (multiple vlans) . Now I need to route only two vlans from the first site to reach some of the second branch networks
let's call them: 1 branch
A-172.16.4.0/24
B-172.16.2.0/24
2 branch
C- 10.10.10.0/24
D- 10.20.10.0/24
E- 10.66.10.0/24
the tunnelis ok From A to CDE . but from B to CDE won't come up. pinging is unsuccessful as well as all other traffic. the connection profile is setup to have both A and B as local networks and A and B by the moment share the same access rules configuration.
logs show firewall 1 let pass and build connections, without denies, but remote firewall does not receive a single packet from the source ip from network B.

Not very familiar with ASA and NAT'ing in general so hopefully, this will make sense.
I've created a Site-to-Site IPSec VPN tunnel with one of our clients (who uses a PIX). The remote user can connect to our local, private LAN servers without a problem. However, when the remote user tries to connect to servers on our corporate network (which is linked over WAN routers from LA to Dallas) they cant get through.
When I run Packet Trace in ASDM on our ASA all is well until the packet attempts to traverse from the Inside interface back through the Outside interface (back to the remote client side of the VPN tunnel).
I see the following "error" within the Packet Trace tool;
-----------------------------------------------------------------------------------------
Type - NAT Subtype - rpf-check Action - DROP
Config
object network obj_any
nat (inside,outside) dynamic interface
-------------------------------------------------------------------------------------------
I've attached my ASA config. The remote client-side address is 74.8.221.195, its being PAT'd to 172.30.12.75 and the remote host/network its not able to reach is 172.30.101.20 ( /24 net mask). The local segment in my LA network is 172.30.12.0/22 and the servers in this network are all able to communicate with the remote client-side user at 74.8.221.195.

I have created a RA VPN with a 5505 using Anyconnect client. My VPN functions perfectly, but now I am trying to limit access so that only one single host on my network can connect. To do this I tried creating an ACL permiting the host and denying all other traffic, but it does not work it seems every one can connect. how I can limit the outside access to a single host?

I am in a test environment using an ASA 55005 and a Cisoc 2611xm router. ASA is running version 8.4 and router is running is ios12.4. My VPN tunnel comes up but I am unable to ping between remote hosts. I used the ASDM and SDM for the configuration. Attached is a copy of both configs.

I found a bug in Embedded Event Manager, on Catalyst 4500-E platform with supervisor V-10GE, on various IOS releases (in particular 12.2-50-SG IP BASE w/o crypto, 12.2-54-SG1 IP BASE w/o crypto, but also other releases included latest 15.0-2-SG1 ENTERPRISE SERVICES SSH).The problem is that when you set up a EEM applet that monitors syslog pattern matching, and you also configure remote host logging *with* the option "sequence-num-session", when the match occurs, the switch reboots with message:
Sw (sometimes prints a number instead)
VECTOR D00
and in some cases performs a second reboot with message:
VECTOR 0
DOUBLE FAULT
The reload reason message is:
System returned to ROM by abort at PC 0x0
The problem does *not* occur if remote logging has not the option "sequence-num-session". I verified this behavior on various configurations (included our production 130K long *and* factory defaults after erase startup-config).The configuration statements that cause reload are, for expample:
event manager applet prova
event syslog pattern %SYS-5-CONFIG_I
action 1.0 puts "configurazione modificata"
!
logging host 172.30.10.1 sequence-num-session

what's the meaning of the output:
Interface Speed Local pair Pair length Remote pair Pair status
--------- ----- ---------- ------------------ ----------- --------------------
Gi0/40 100M Pair A 2 +/- 4 meters Pair A Normal
Pair B 2 +/- 4 meters Pair B Normal
Pair C 2 +/- 4 meters Pair C Short
Pair D 2 +/- 4 meters Pair D Short
From the command
test cable-diagnostics tdr int gi 0/40
It's normal?If not, then. the problem is on the cable or on one of the interfaces?The interface is connected between a fastethenert on a 2811 router and a 3560-48 switch.The cable is a straight through cat 5e cable. (I have changed several cables with same result).

When I'm pinging my mail server, it gave me different IP's at different times. As the mail server is actually owned by us, I would like to know if that is possible without the IP actually being changed by someone. This is really critical for me. I didn't mean to cross post so providing the URL of the other place where I posted..
If you'd like I may attach the screenshots for the same, but don't think that will server any purpose.

Windows 2003 R2 Server machine cannot be pinged, not XP? I'm running a highly modified version of Windows 2003 R2 to make use of an old PC. It connects beautifully to a Verizon router (I can browse the Internet), but I can't figure out how to share folders on my network. I have a Macbook and Win7 machine and both cannot see this old PC on the network. I have tried to ping the old PC from my Win7 machine, and it will only timeout. Below is some relevant output from the old PC

We have a 2960 switch (switch2), whose Management IP cannot be reached/Ping'd. Could not Ping . We have checked the following, but still no clue on the root cause. Haven't tried a reboot yet.
Topology.
All switches are cascaded through trunk and allows all v lan's.
L3switch1 <-> switch1 <-> switch2 <-> switch3 <-> L3switch2
Switch 2 has correct ARP entries for the other switches that we try to ping.Mac address table is fine.Switches other than Switch 2 has proper ARP and Mac entries.This Mgmt v lan is not pruned across any trunks. (we are able to ping switch3 crossing switch2 when tried from switch1)Switches are running PVST and convergence is fine.No access list to deny the traffic.Tried sut/no shut on the V lan interface.
But still switch 2 could not be reached.

I just got my dad's old notebook (VAIO VPC F223FB) which is better than my older one. So, I did a backup and then managed to clean install a Windows 7 Professional x64.At first I had a problem with the drivers, because the internet wasn't connecting and the USB ports weren't detecting my External Drive. So, I tested other USB port and got it. Installed the drivers and I could connect to the wireless network. But it doesn't detect the ethernet cable! And I want it detecting because then it's faster. I already tried downloading the Ethernet Controller driver. At first, I downloaded through Sony's support site but it didn't recognize the driver. Now, it recognizes but still doesn't connect it. And when I tried Solving Connection Problems, it said the network gateway was accessible but Windows can't receive Internet network traffic.

I am in the process of switching firewalls. Currently I have a Sonic Firewall inplace. I have been tasked to switch the firewall out with a cisco asa firewall 5510. The sonic firewall currently allows email traffic, web traffic, and dns traffic. When I use the current config below on the asa I am unable to receive email from the outside network. I can send and browse websites but I cannot receive email.

I have a problem with siemens industrial profinet apparatous and my Cat2960.
Siemens host can be pinged without any problem but they are not able to do any other kind of traffic. If i look at the interface I can find that all ingress packet are UNKNOWN DROPPED.
I found a document where si explained that "probably" siemens host are using packet with 802.1p header and vlan 0.
I tried the following tests:
1) port in access mode - failed
2) port in trunk mode with native vlan - failed
3) port in access mode with voice vlan - failed
4) port in acess-mode with voice vlan dot1p - failed

There is a device which is connected to the PC via Lan. I have an exe file which is supposed to get connected to that device and perform some operations. However, the problem is, the exe file tries to connect to the local host ip address 127.0.0.1 and i cant change the ip since it's been coded.So, I'm wondering if i can use the device connection (which already has a different ip like 169....) as a local host connection. So whenever it tries to connect to the loopback 127... it automatically connects to the external device.
