Sending But Not Receiving Packets

Sep 26, 2011

Our computer is sending but not receiving packets. We've tried 3 different wi-fi adapters, and that wasn't the problem. We have no idea what's wrong? It won't pick up any wireless signals by the way, and it works fine while connected via Ethernet.

Computer Not Sending Packets But Receive Them

Sep 2, 2012

Alright, so we have about six computers on average all on at the same time, working just fine, last night one of the laptops just, stopped working, saying there is no internet access, With every attempt it doesn't send any information. When I disconnect it from the wireless, then reconnect it, it immediately receives packets but won't send any.

PC Sending Packets To Random IP's From A Range Of Ports?

Aug 27, 2012

So this is somewhat of a strange issue. I have a program called PeerGuardian 2 and it allows me to simplistically see the packets being sent to and from devices on my home network. It's showing that my computer is sending packets to random IP addresses, some of them reoccur, on a massive range of ports all going in order.

(example)
From 192.168.1.253:6812 - To 74.120.148.2:80
From 192.168.1.253:6813 - To 74.120.148.2:80
From 192.168.1.253:6814 - To 74.120.148.2:80
From 192.168.1.253:6815 - To 74.120.148.2:80
From 192.168.1.253:6816 - To 74.120.148.2:80
From 192.168.1.253:6817 - To 74.120.148.2:80

This happens in spurts and it usually sends 20-40 to varying IP addresses in a matter of a few seconds. I asked my ISP if they understood what this was and it stumped the technician I spoke with. I also have run multiple virus/malware scans and everything comes up clean.

Can't Connect To Internet But Local Area Network Is Sending Packets?

Mar 17, 2011

I can't connect to the internet. When I double click Local Area Network under Network connections it says it has both sent and received packets. It is set to automatically acquire an ip address. The computer is connected to a router. I can ping 192.168.1.1 but when I try to reach my router's settings it says page can't be loaded. I tried to hook the computer up directly to the modem and connect that way. It said it was connected and it was sending packets but I still couldn't do anything. I've turned off the windows firewall. The computer is Windows XP SP1

Cisco Switching/Routing :: 7200 - Netflow / Packets Not Sent?

Jul 23, 2012

router 7200 (12.2(33)SRE1)
 
two interfaces with traffic going through, placed in a Data-VRF
 
Another physical interface and loopback interface in the global routing-table.
 
ip flow ingress on all physical interfaces configured
 
It was running for at least a year: I was getting netflow packets on my analyzer from the box. Since a couple of weeks I get no netflow-packets anymore.debug ip flow export  tells me "IPFLOW: Sending export pak to ... port 2055"
 
But the packet is not leaving the box. By setting up an ip sla monitor udp-echo I simulated some traffic (udp/2055) which is leaving the box.

Cisco WAN :: 3750 And 4507 / 1Gbps Link / Sweep Ping Dropping Packets?

Dec 29, 2010

We are testing a new 1Gbps WAN circuit between 2 sites. We have cisco 3750 and 4507 on each end. Every time we run extended ping sweep ranging from 36 to 18024 bytes the packets are being dropped randomly once the size goes above 1500 bytes. Our ISP claims Demark to Demark test are clean and they don't want to acknowledge the problem, they blame our switches. To prove the problem is not on our end we've put different switches at each end, still facing the same issue. Ping success rate is around 98 to 99 percent.

I have a problem with the 6500 not exporting netflow data. They are not exported due to no fib.I have read somewhere that this has something to do with VRF.

Cisco Switching/Routing :: 3750X Netflow Packets Are Not Being Exported To Server After Update

Feb 5, 2012

Basically I have netflow which i'm trying to use to export to a netflow collector. I'm pretty sure that the 3750-X does support netflow. I've recently updated IOS on the 3750-X to support flexi netflow.For some reason the netflow packets are not being exported to the server. I'm using Opmanager which should present the netflow stats in the form of a graph. I'm using a universal IOS image. (C3750E-UNIVERSALK9-M), Version 12.2(58)SE2 3750-X WS-C3750X-24T-S

Packets Activity Stops But Still On The Network?

May 11, 2011

During the last month or so my internet connection keeps stalling and will not work until I repair the connection, however I am still connected to the network, I just can't send or receive packets. In particular when I am downloading things, it will stop after 2MB is downloaded or 300MB, it just random. After sending/receiving 7,000 packets or 700,00. This only happens to my computer with the wifi adapter. Prior to this I didn't have any issues for over two years. My phone and laptop still connect via wifi to the internet. And the xbox and blu ray player are connected via ethernet and have not had any problems. The log for my router states "deauthenticate reason 3", which I have found to mean "The access point went offline, deauthenticating the client". So, I figured that the issue could be the wifi adapter which I installed on the laptop and that too never had an issue. I used inSSIDer 2.0 to see the close by networks and changed channels to get away from the strongest ones. I tried switching to wireless n only instead of g and n, the problem still persists.

Then I figured the issue must be my computer and no malware, spyware, adware nor any virus was found. The same thing happened while in safe mode. I also tried the winsock fix to no avail, reinstalled the wifi adapter and made sure all firmware for the router and adapter were up to date as well as XP. I also tried with my firewall shutdown but I still loose the connection. So I then reluctantly did a clean install and even with the bare essentials it still stopped working. I also bought a 15ft USB extension to get a better signal but still, even though I have a good or excellent signal I still have problems. My latest thought was this was the only machine running firefox 4 so I went back to 3 and that didn't either. I checked my usage with my ISP and I am no where near the 250GB a month.

Linksys Wireless Router :: WRT400N Stops Routing Packets Randomly?

Aug 19, 2012

This happens intermittantly. This results in most connections (but not all) being dropped. I will be unable to connect to web servers. My connection to videogame servers will drop. However, AIM will stay connected. These were done simultaneously. The same thing happens with my Cisco AE1200 and a D-Link 802.11g adapter I have. Disconnecting my adapter and reconnecting it solves the problem. I have tried doing a factory reset on the router and installing the latest firmware. It seems to happen more frequently when I am doing a lot of throughput (downloading a game on Steam, for instance) but other times it will happen when all I am doing is playing a game (like Tribes Ascend) which uses very little data. This is extremely frustrating. When I pay more than $150 for a piece of networking equipment, I expect it to last more than 3 years.

Cisco Switching/Routing :: 4507 - CPU Going At 50 To 60 Percent

Nov 19, 2012

I am having a Cisco 4507 switch. The CPU on the switch is running between 50% to 60% constantly. To troubleshoot I collected some logs using debugs & show commands.
 
debug platform packet all receive buffer
show platform cpu packet buffered
 debug platform packet all count
show platform cpu packet statistics
 show processes cpu sorted | exc 0.00
show platform health
show platform cpu packet statistics
 
show platform health output shows the below process crossing the target value.
 
%CPU   %CPU    RunTimeMax   Priority  Average %CPU  Total
Target Actual Target Actual   Fg   Bg 5Sec Min Hour  CPU 
Stub-JobEventSchedul  10.00  13.41     10     47  100  500   13  13   10  5462:52

What I need to know is, though these process are running in Low Priority, will there be any issue if the CPU goes high due to these process.

Cisco :: 4507 - Filtering Outbound Sys Log Messages

Apr 10, 2013

How can I filter outbound sys log messages, so they include only configuration changes messages..
 
On Cisco 2900 I used:
 
logging discriminator CFG LOG msg- body includes "PARSER" | "CONFIG"
 
logging host x.x.x.x discriminator CFG LOG
 
logging x.x.x.x
 
How can I do the same on 4507? This feature on Cisco routers is called "Reliable Delivery and Filtering for Sys log" and is available for 12.4(11)T  and 12.2(33)SRB (7600) . I am running Version 12.2(25)EWA6 on my Catalyst, so it is not available.
 
The software I am using is a simple solar winds sys log server.

Cisco WAN :: 4507 Redirect Web Traffic Via Policy

Jul 12, 2011

We have W2K3 domain with Catalyst 4507 routers.Client (laptop, tablet etc) needs to redirect web traffic (port 80) to a proxy server that listens on port 8080.
 
Before you ask, this cannot be done using a PAC file distributed via Group Policy or the like because these devices are not controlled by us. These devices are client owned and could be non-Microsoft OS and/or non-IE browser. The theory is to have a WiFi network where clients can bring whatever they like - iPad, Android, Windows, whatever it may be but we do not control them and therefore cannot send a PAC file to it. In the case on Android it does not have a proxy setting even if we could force something.
 
I've looked at Policy Based Routing which appears to do half the job. I can route a web request that is on port 80 to a new location ie our proxy server. But the problem is that it arrives on the same port 80 when the proxy server only listens on port 8080.

Cisco :: LMS 3.2.1 Sending More Pings Than Thought Usual?

Aug 9, 2011

I'm looking for troubleshooting LMS 3.2.1 and the ping/ICMP traffic it transmits.A lot of my devices are receiving a lot more pings from LMS than I would have anticipated.I don't run PING sweeps in Device Discovery or CM-UT. I've even disabled DFM polling in a hope to trace the source of these PINGs. Any list of which modules use PINGs so I can turn them off and track down the offender.I really only want to manage the known devices I already have via SNMP alone. I don't require LMS to be PINGing for discovery or reachability purposes.

Cisco Firewall :: ASA 5550 Sending Reset With TTL Of 255

Oct 3, 2011

I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
 
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
 
The characateristics of the reset packet are the following:
 
- It is the only packet with a TTL of 255.

- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.

- It has a correct ack number.

-Before the reset is received, there are a couple of retransmissions of the last packet sent.

- We´re handling a VPN tunnel between both servers.

Cisco Security :: ASA 5520 No Longer Sending Log To FTP

Sep 22, 2011

We have a ASA 5520 which is configured to send log files to an ftp server.  It has been doing that until recently I found out that it stopped sending the logs on August 11.  I can't remember what I have changed in the ASA config to make the ftp stop.  I changed the ftp config to another server but it won't upload any log file.
 
What can I do to make the ASA save the log buffer to the ftp server again?
