eth link is not ready

M.S — Mon, 10 Aug 2009 13:13:49 GMT

Hi All,

I have two servers connected to each other with a cross cable. The connection was up and everything was Ok.
We had to change the NIC of one server, and after that the two servers are unable to connect again and we are getting the following in /var/log/messages:

Aug 10 12:31:49 system2 kernel: ADDRCONF(NETDEV_UP): eth2: link is not ready

eventhough that the cross cable is ok, but we are still unable to connect.

Can u please comment on this behavior if u face it before.

Thx in advance.

I suggest you to always use a swiched connection (in a separate VLAN if neccesary).

You can try setting the speed and duplex mode with ethtool (if not GB ethernet) on both sides.

even if there is a problem with the negotiation still the "link detected" should be "yes". post the o/p of ethotool ethx

which server you get the error log eth2: "link is not ready" ?
-you have to check kernel driver, may be need issue command to reclaim drivers :
#/dev/MAKEDEV

and also which flavor of Linux you use ?
-commands are different from version to version

and last thing to consider
- be sure of your ethernet card is good
