Strange eth0 interface traffic

For almost a week now, I noticed that there is some traffic over the eth0 interface every 3 seconds (90 - 180 B/s). Even when I close all applications like Firefox and Kmail. I don't know what to google on because I don't know what this all about. So, any hints, suggestions are very welcome.

Oh yes, windows boxes are or used to be very chatty
I'm surprised you don't get more traffic from your windows box.
Oh and in this case as it is an incoming connection it is normal that netstat | grep doesn't output anything, I was mostly thinking about outgoing connections.
If you are using dhcp then things can be simple or tricky, if you can configure your router to always give a certain card the same ip then things are easy, just add the correct entries to both hosts files, if you can't then IPs may change and the annoyance may come back.
I guess you shouldn't worry too much about that though, it seems to be legitimate traffic and a few bytes every 3s is not something that will slow down your home network

Strange Exchange 2010 Traffic

Hi Guys,
I've a strange and mysterious Traffic dropping all the network caused by one of the HUB\CAS servers.
We have Exchange 2010 Environment 2 DAG Members and 2 HUB\CAS Servers we are using WNLB as a load-balancing Solution.
We have two physical hosts and we virtualized the all servers mailbox and HUB\CAS
MBX-01 -- HUB-CAS-01 on HV1
MBX-02 -- HUB-CAS-02 on HV2
When Both servers are up strange traffic begin and all telephony system "Avaia" go down.
I've disabled the replication on the MAPI network on both DAG members to ensure that the replication traffic goes throw the private network and changed the mode of NLB " Multicast and then Unicast" and nothing changed any ideas.
All servers running Exchange 2010 SP3.
Thanks
Best Regards
Mohamed Attia

Hi,
Based on the description, you used WNLB as a load-balancing Solution, however, it is recommended to use the HLB instead in the production environment.
From the "Network requirements" topic in the article
Planning for High Availability and Site Resilience, DAG must have a single MAPI network, which is used by a DAG member to communicate with other servers (for example, other Exchange 2013 servers or directory servers), and zero or more Replication networks,
which are networks dedicated to log shipping and seeding.
So nothing changed, even though you disabled the replication on the MAPI network on both DAG members. It is the expected behavior.
Do you connect the telephony system "Avaia" to an Unified Messaging server?
Best regards,
Belinda

Monitoring interface traffic

I'm using a solution to monitor the traffic passing through the interface
SWCORE connecting with my router.
The Linux machine (sniff) has two interfaces (eth0 and eth1)
Etho (manages the machine) connected to the interface to another interface g1/18
(Sniff) connected in g1/27.
Add the following command:
monitor session 2 source interface Gi1/48
monitor session 2 destination interface Gi1/27
But I don't capture nothing.
I show monitor out following:
Session 2
Type : Local Session
Source Ports :
Both : Gi1/48
Destination Ports : Gi1/27
Encapsulation : Native
Ingress : Disabled
Learning : Disabled
Do what doing wrong? Help me??

try this "monitor session 2 source interface Gi1/48 ?"
Doesn't if show an option to span ingoing, outgoing or both traffic directions?
I think you need both
Do you see traffic on the spanport Gi1/27 if you do a "show interface Gi1/27" ?
The counters should go up
The interface Eth0 should be in promiscuous mode to capture the traffic other then for its own mac address or broad/multicast
Cheers,
Michel

Issue in Sub-interface traffic on cisco 7609-s router

Hello please support,
I configured sub-interfaces and it is working properly, but some time sub-interface show traffic more then physical interface .
Like
int gi 3/32 0.13 Mbps 12:00 PM
int gi 3/32.11 855 Mbps 12:00 PM
as per my knowledge physical interface have cumulative traffic of all sub-interfaces.

I have not that graph so I am just guessing that you are noticing the difference between policing and shaping. It seems to me you are applying these techniques on each platform on a different way. Try to shape/police in the same order or only to shape.
Hope to help

UPDATE...
I have been in safe mode for a while... When I was login into safe mode the I suffered one of those graphical glitches... I took a photo. After that, when it finished to load the screen went black and nothing more happened... The computer was working... but not graphical interface at all... just a black screen.
Then, I decided to force to turn off.... and try again to login into safe mode. That time worked well and normal.
However, while I was in safe mode the mac behaved strange graphically, as you can see in this video. I really do not know if that is a normal behaviour in safe mode. Finally, while I was finishing the email to reply the apple support a heavy graphical glitch happened after the screen went black, as you can see in these photos ( 1, 2 and 3). I decided to turn of the computer and back to the normal mode.
I have collected another console log, it can be seen in the previous link to the error logs or in this link. The glitch occurred around 14.10 h today.
Thanks in advance for the help and your time!!! it is really appreciated!!!!

Intra-Interface-Traffic fails at first try - second try works

Hi,
we are running two ASA5550 as fail-over.
Everything works fine. But there is still a little "bug".
same-security-traffic permit intra-interface

Now, let's open an PostgreSQL-Connection from 10.10.1.22 to 10.10.1.8 (same subnet, same interface "IT").
First try (using psql for a connection), I get

in the ASA log.
psql now runs into a time out.
Starting the second try, the ASA doesn't report any packets and the connection is established.

Phillip,
Based on the syslogs the reset packet is coming from another device "Reset-O". The best way to troubleshoot this issue will be applying captures on the IT interface in order to track the source MAC of the reset and to have a better picture of the traffic flow.

Monitoring tunnel interface traffic

We've integrated WLSM with IDSM-2 and want to monitor wireless traffic terminating on tunnel interfaces. Can't find a way to configure SPAN or VACL on IOS 6500 to capture traffic. Any suggestions?

Disable eth0 interface on boot

Hi, I have both wired and wireless eth0 and wlan0 interfaces
I want only to use only wireless, but on boot if I have the eth0 cable disconnected it does not continuing boot until cable connected.
But if I have cable connected it boot normaly.
Can I disable eth0 on boot to avoid lock on boot process if cable not connected?
Regards

You might try:
ewaller@odin:~ 1001 %pacman -Ss cable
extra/ifplugd 0.28-11
A daemon which brings up/down network interfaces upon cable insertion/removal.
ewaller@odin:~ 1002 %
Put it in the DAEMONS array before network.
How are you configuring the Wireless? Wicd and Networkmanger should both handle this

IDS-4210 picks up what IPS-4240 misses, strange duplex/interface problems

I just installed a IPS-4240 inline on our primary internet inbound connection. I decided to leave the 4210 in place for a week or two while I tuned the signatures. It is receiving a span of the same traffic that the 4240 is receiving.
I noticed today that the 4210 is picking up sig 3250 and the 4240 is no. The first thing I checked to make sure that the 4240 has this signature enabled, and it is. Anyone have any thoughts? BTW, All sensors are on the same version 5.1.1 and running s211 and managed through VMS.
I would also like to mention that I had issues on the 4240 and its interfaces. Management only runs at half duplex and the interfaces that connect to our PIX. I ended up having to put a switch between the 4240 and the Pix 515e to solve the duplex issues.
Anyone have any thoughts on this part

I had the same duplex problem with my 4240 sensor connecting to my PIX. The only way I could get it to work without errors is to set both the sensor and the PIX interfaces to auto/auto. I worked with Cisco on this problem. No resolution, just the workaround. As far as sig 3250, IPS and IDS signatures may be a little different. I assume you span from the inside and run your in-line outside your firewall? If this is the case, then the 4240 sensor may see different traffic than the 4210.

VIPCA showing only eth0 interface

Hi all,
I'm installing Oracle 10g R2 2 node RAC on RHEL4 U4 for R&D purpose. And i'm following the steps given in http://www.oracle.com/technology/pub/articles/hunter_rac10gr2.html article.
While installing clusterware software asked me to run orainstRoot.sh and root.sh script on both nodes. On node1 both the scripts ran succesfully and on node2 root.sh script gave the following error..
The given interface(s), "eth0" is not public. Public interfaces should be used to configure virtual IPs.
It is given in the doc that, the above error can be resolved by running the VIPCA GUI utility on the node where this error is occurred.. when i ran VIPCA utility on Node2..in Network Interfaces section, it is showing only eth0 (public) and it is not showing eth1. But in the above given link, it is mentioned that we need to select both eth0 and eth1.
Can anybody tell me what might be the problem?
Thanks,
Praveen

Hi,
Please upload/review your ifconfig -a output on both nodes. you should see 3 IPs on each node, one for the interconnect, one for the public and one for the virtual. These should be persistent after a reboot, and match. eth0 on one node should be eth0 on the second, etc.
If this is done, you should not have an issue with VIPCA.
Thanks,
Idan.

Issue with eth0 interface

Have a rh9 system, with /etc/sysconfig/network-scripts/ifcfg-eth0 contents :
DEVICE=eth0
IPADDR=140....
NETMASK=255.255.254.0
BROADCAST=140...
GATEWAY=140....
BOOTPROTO=static
ONBOOT=yes
During system bootup, eth0 never comes up automatically. "service network status" shows eth0 in "configured devices" only, not in "currently active devices".
"chkconfig --list network" shows :
network 0:off 1:off 2:on 3:on 4:on 5:on 6:off
After bootup, typing "service network reload" from command line activates eth0. Not sure what else could be stopping eth0 from coming up automatically upon reboot.
Any suggestions ? Thanks.

hi
Try "dmesg|more" look for you dev(eth0 ) see if the is any errors anound it

Statically assign xenbr0 (eth0) interface to one specific NIC

Hi,
I have multiple NICs on my Oracle VM server. Everytime it reboots, xenbr0 (eth0) will be dynamically assigned to one of the NICs card, depending on which one comes up first. My xenbr0 is assigned a public address. That means that I will not be able to connect to the server remotely if it is assigned to a different NIC. Can someone tell me how I can assign xenbr0 to one specific NIC statically?
Regards,
Ming

In Oracle VM 2.2, it automatically creates xenbrX bridges for each ethX device it finds. If this is changing, it means your NICs are changing on boot. You need to ensure that your ifcfg-ethX device configurations have HWADDR fields to fix them to a particular NIC.
In Oracle VM 3.0, we do not create xenbrX bridges by default and this is all handled by the Manager.

Bringing up interface eth0: e1000 device eth0 does not seem to be present, delaying initialization.

I performed a software reboot on the MSE3310. After the reboot the MSE was no longer visible on the network. I went and consoled into the device and it was operational. I ran the msed stop and msed start commands. I got this message when it tried to load eth0

Earlier in the day I had updgraded the firmware from 6.0 to 7.0.230.0.
Can I recover the eth0? Is this related to the firmware upgrade?
Thanks.
Jason

Tarik,
This procedure worked great! After adding the HWADDR parameter to the eth0 config file and rebooting the server, we are now able to access the server on the network again. Thank you very much for the quick reply!
Here is the procedure if others need this.
ifconfig -a showed the eth0 interface was renamed to _tmp462132856
[root@MSE-CPW-01 ~]# ifconfig -a
__tmp462132856 Link encap:Ethernet HWaddr 00:15:17:F1:4D:C7

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
          Interrupt:169 Memory:e8180000-e81a0000

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Then issued
vi /etc/sysconfig/network-scripts/ifcfg-eth0
to edit the file and add the HWADDR=xx:xx:xx:xx:xx:xx
Then issued a 'shutdown -r now' to reboot the server
After a reboot, network connectivity was restored!
Thanks!

Can wicd simultaneously connect two networks via different interfaces

hi, recently, I installed wicd. I am tired for figuring out of NetworkManager stuff.
however, for same reasons, I could not configure my ethernet and wireless interface at the same time.
for example, in my case, I have enp0s25 and wlp3s0 interfaces. however, wicd only allow me to connect one at a time. especially when I connected enp0s25 via wicd-curses, it actually disabled the wlp3s0. (the interface is set down by wicd, but I still can see the available network, very strange)
is there a way to deal with that ?

Wicd is kinda strange, it usually picks the wired over the wireless (and there is an option for that). You can get it, by allowing wicd to connect wirelessly, and manually dhclient the eth0 interface. Netctl can help in this allowing both interfaces to go without manual intervention. The only difference is you won't be roaming like you can in wicd.

[SOLVED] Issue with eth0 (eth0: timed out)

Hi there people, just installed Arch on my PC (again). The first time I had no problems with this, but now it is really bothering me. Well, my PC only access the net via wireless, so I have no wired connection for it. Here's my /etc/rc.conf:
# /etc/rc.conf
eth0="dhcp"
wlan0="dhcp"
wlan_wlan0="wlan0 essid MySpot key ABCDEFABCDEF1234567ABCDEFC"
INTERFACES=(eth0 wlan0)
Well, everything is working fine, I can get access to the internet on bootup. My only concern is that my system is taking awfully long to boot. It takes about 1-2 minutes on "::Starting Network", then it shows me "eth0: timed out". Then it takes about 10 secs to start my wlan0 interface and the system finishes booting. I had previously installed Arch 2008.12, and the Starting Network only took about 10 secs to start my wlan0. I have already tried commenting out the eth0 line and putting a ! in front of eth0 on INTERFACES, but doing that only shows me an error message for my wlan0 and render my internet unusable on system bootup. So, my questions are:
1) Do I really need the eth0 interface for my connection (since I'm using wlan0 for wireless connection) ? Why can't I comment it out?
2) If I really need eth0, how can I make my boot time go faster, or how can I make it not time out?
Thanks in advance for any help given...
EDIT: problem solved, see Post 8 below for answers...

Thanks for answering. Well, I think eth0 is being detected correctly. Here is the output for ifconfig:

Well, I hope that can help. Searched the net and the forums, and every problem related to this is with people who are actually trying to use the eth0 interface for connection. In my case, I don't think I need it, I only need the wlan0. What I'm trying to do is get rid of eth0 while letting wlan0 work.
