Ping stops after cable connect
 

Hello All,

When my system boots up the ethernet port which is connected to my PC pings fine.

When I remove and insert the cable on either end, the ping stops and doesnt restore.

Messages I see is below.
libphy: stmmac-1:03 - Link is Down
libphy: stmmac-1:03 - Link is Up - 100/Full

Now if I do, ifconfig eth0 down and ifconfig eth0 up, the ping starts back again. Whats different is I see the link ready message which I didnt see when I plugged the cable back in.

eth1: device MAC address 00:11:ca:99:00:b1
IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
/etc/netplug.d # libphy: stmmac-1:03 - Link is Up - 100/Full
IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready

What may I missing in my netplugd ?

"When I remove and insert the cable on either end, the ping stops and doesnt restore."

Not sure that is a fault. What exactly do you wish to prove by this test? Kind of a lot going on in this. What is this Long Range Systems Inc. 00:11:CA?

I'm not sure whether you are referring to let your system interfaces to automatically detect the connection when it gets disconnected.

If you're using static IP Addressing.

Try going to: /etc/network/interfaces

And set the settings of your NIC, to auto. see sample config below.

My problem is my system is pinging a host just fine, but after the cable is removed and replugged, the pinging stops. Until I do ifconfig eth1 down and ifconfig eth1 up. After doing that the pinging resumes.

^ isn't that the expected behaviour?

Expected behaviour would be to not do the ifconfig eth1 down and ifconfig eth1 up wouldn't it ? Plug the cable and the interface gets configured and its good to go without doing any manual commands.

Have you tried changing the config to: auto eth0

Edit, try this also:
set eth0 config to:
ONBOOT=yes
check network level, type this at the command line:
/sbin/chkconfig --level 2345 network on

actually you're right.

for me it raises the questions what actually manages your network connections.
on my system it's systemd, and nothing else:(*)
i could imagine networkmanager interfering, if you use it.

what distro, setup?

(*) on my distro, netplug isn't even in the repos anymore, i think systemd long since provides that functionality.
which systemd version?
