I am working on a rather nasty issue with regards to networking on a Dell R220 in combination with Ubuntu 14.04 Server.
When the OS is loaded & I hot-plug the IP cable, the network link is not automatically re-established. I've gone through various options related to the OS (IP configuration/kernel version/distro version/etc) but I haven't found anything that could explain this.
Hence my attempt here, I hope someone found this issue before and knows the answer, or otherwise might have some helpful tips & tricks to help me find my answer.
