If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

Networking :: Microsoft Process Listening On Box?
Sep 4, 2010I run various manual checks on my system to see if there's anything I can't account for and just one such instance just got thrown up here. I reproduce the output from netstat below. I see there is something called "microsoft-ds" shown as listening. What on earth is this doing on my PCLinuxOS box? I have googled it and there does appear to be some security issues related to it for Windows users and all the advice relating to it that I could find is for Windows users, but I am just baffled as to what this is doing on my Linux system.

Networking :: Make P2p Work If No Ports Listening
Oct 18, 2010In emule p2p filesharing there's this thing called the id that is low if you do not configure your router for certain ports to be listening for incoming connections, forwarded by the router to ports on your pc. When the id is low, your downloads take longer or something like that. But if you have no listening port, how can a peer download from you?

Fedora Networking :: Tool To Create Multiple Listening Servers On TCP And UDP Ports
Jan 17, 2011Looking for a test tool where I can fire up any number of ports (TCP and / or UDP) to listen on.
I am currently getting my using nc but its only 1 port at a time (i know I can open up multiple sessions but thats cumbersome), it can't do UDP, and it closes at the end of the session.
A friend has suggested socat but it looks pretty much the same except it can do UDP, but also cumbersome, I have to manually output to a different file per port, etc.
Basically its so I can quickly test firewall and NAT rules.

Jan 11, 2011I am running Ubuntu10.04 as a Virtual Machine in virtualbox.I changed my Networking settings from NAT to Bridged Adapter and manually assigned IP addressing information for eth0 in /etc/network/interfaces. For some reason doing /etc/init.d/networking restart didn't bring up the network interface. So i replaced the new /etc/network/interfaces file with the original and rebooted. Now I have eth1 in place of eth0. Under System>Preferences>Network Connections I have Auto Ethernet and eth0. However running ifconfig shows lo and eth1.

View 2 Replies View RelatedNetworking :: Changing The Permissions Of Eth1
Sep 14, 2009I often run "gulp", a networking utility, to capture data from an instrument on "eth1". By default gulp must be run as root to have access to the ethernet port, and when I'm the only one running it, that's fine. But I need to let several other users to capture data and don't want to give them all sudo permissions for both gulp, and more importantly, 'chmod'. Is there anyway to change the permissions of eth1 to allow all users to open it and avoid sudo entirely? This is on a Red Hat/Fedora machine.

Fedora Networking :: 12 - Networking Eth0 And Eth1
Jan 12, 2010I am trying to setup linux box as router.
What i am trying to do is:
1. I am trying to setup NIC via network not NetworkManager
2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1
3. #Ifconfig shows my nic and ip
4. restart the service network .
5. #ifconfig shows nothing. NO NIC card
I dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)
I tried to configure the NIC with Network Manager
When ever i restart the network service i have no out put from ifconfig
I tried to configure the NIC with #setup command as well and select the dhcp option
I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/

Ubuntu Networking :: Don't Seem To Have All Variables For Eth1 Inet
Apr 28, 2011I'm having a strange problem. I'm using Ubuntu server 10.04 LTS and I want to setup a system with 2 network interfaces: eth0 and eth1. However eth1 does not come up at boot I have a screenshot of my /etc/network/interfaces file I don't see what is wrong. eth0 gets it's adress from DHCP eth1 gets a static adress. When i try to restart networking it quits with this message "don't seem to be have all the variables for eth1 inet" Can anyone point out what I'm doing wrong? if i do 'sudo ifconfig eth1 192.168.3.1 netmask 255.255.255.0 up' eth1 comes up

Networking :: Server (eth1-connecting To The Windows XP PC) = 192.168.4.3?

I can still ping the router (from the server) but I cannot ping the PC
if I try and add another route such as: route add -net 192.168.4.0 netmask 255.255.255.0 gw 192.168.4.4 it wont let me add the rule I have a feeling i am doing something really stupid here with the addressing scheme,

I want to change them so that the "Intel" become eth1 device and the "National" become the eth0 device.
I already tried these steps :
1. I disabled the Network Manager and enabled network
2. Edit the /etc/udev/rules.d/70-persistent-net.rules like this

3. Change the /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-eth1 MAC addresses.
4. Reboot
5. After it bootup the Fedora can't recognize the devices, if I do ifconfig -a it shows "eth0_rename with FF:FF:FF:FF:FF:FF mac address".
Fedora Networking :: Why Primary Interface Is Eth1 Instead Of Eth0?
Jan 31, 2010I have two network interfaces on my computer but only one of them is connected to an Ethernet cable. Until now on every Fedora release, the activated primary interface has been named as eth0 and everything has always worked well without any problem. Recently I switched to Fedora Core 12 and surprisingly I observed that for the first time, my primary interface has been considered by the system to be eth1 instead of eth0. I tried to replace the content of ifcfg-eth0 by ifcfg-eth1, yet system gave me an error that there was MAC address mismatching. I conserved their MAC addresses in their files and just replaced other connection parameters ( such as IP ADDR, NETWORK, NETMASK, etc.) but it did't work. When I do "server network restart", the command blocks.
As I try to install oracle on this system, regarding the fact that oracle requires static network configuration on the primary network interface, I don't know how to proceed in order to set eth0 as my primary interface (or rather set the current eth1 to eth0 because it is actually eth1 that refers to my activated primary network card).Just one more time, I would like to remark, that with previous versions of the Fedora Core, on the same computer (with the very same two network cards) I never had problem and I had installed oracle on the system with success, having the statically configured eth0 correctly detected by the system.

Ubuntu Networking :: Stop Internet Access From Eth1?
Aug 24, 2010I have a bit of a "unique" situation here. I have myself plugged into two networks - since we run two networks here at work (long story, we merged and never combined them due to two different companies) and want to block ALL internet access off eth1, and only have it off eth0. I only want traffic from 192.168.67.1-192.168.67.255 allowed on eth1, but everything allowed on eth0. Or is there a way for the internet/applications to be on eth0 instead of eth1? Would I use iptables or something?

Networking :: Cable Disconneciton Eth0 And Eth1 Behaviour
Mar 10, 2010I need to have the configuration showed on the attached file. I have two machines, one PC (ubuntu 9.10 ) and one embedded CPU with a tailored linux version starting from 2.4.31 linux kernel with Busybox running on PPC architecture.
PC address is 192.168.30.70.
On CPU board I have two ethernet interfaces with addresses :
eth0 192.168.30.30 netmask 255.255.255.0
eth1 192.168.30.40 netmask 255.255.255.0
PC sends messages alternatively to 192.168.30.40 and to 192.168.30.30 .Between two machines there is an ethernet switch to allow messages flowing.
I use ping (from two shells on PC I ping the two addresses on CPU) to simulate messages from PC to CPU and I see this behaviour:
Starting from a situation in which CPU responds to the pings I try to disconnect cable connected to eth0 on CPU. I cannot see any interruption on ping reply on the eth0 port. If i reconnect the cable on eth0 and I disconnect cable on eth1 there are no reply to the two pings (neither from eth0 nor from eth1). It seems that all data flows on one cable just because the addresses are on the same subnet. Is this right?
If this is the right behaviour how can i separate data from PC to CPU in order to force packets to flow on two cables and avoid this sort of internal routing beetween eth0 and eth1?
