Strange network connection.
Greetings,
Recently I was checking out Hardinfo 0.5c and noticed that there were some ip connections listed as ESTABLISHED when I had no browser or other internet software active afaik.
I decided that since I knew not how to flush those connections to bring down eth0, my wired connection and only connection for this box. So I did:
then
My connection is static setup in /etc/network/interfaces. The interface took a short while to return to the prompt. I do an:
shows the system is up. However, when I ping my router, I get a 100% loss. I tried:
Code:
sudo /etc/init.d/networking restart/force-reload/stop/start
all the available of above to try and reset the connection and bring up the network. No go.
I then tried:
It returned my routers ip address and I noticed something funny no mac address. So I just rebooted the machine and normal operation returned. I ran arp again and this is what was returned:
Code:
[myuser@mydesktop ~]$arp
Address HWtype HWaddress Flags Mask Iface
192.168.1.1 ether 00:18:01:6c:03:5f C eth0
[myuser@mydesktop ~]$
This looks more like it. After all this my question is: What could I have done to flush a cache or reset the network to allow a simple reconnection w/o incident? I'm running Ubuntu 9.10, I removed network manager.
