Due to its non-standard nature, WDS is often implemented differently in wireless drivers and vendor firmwares making them incompatible with each other.
Do I need to restart the server after a kernel update?
To actually use the new kernel you will have to reboot. Do you have to reboot immediately after installing the update ?
It supports all new drivers that have been added to the kernel recently.
The old tool iwconfig, which uses Wireless Extensions interface, is deprecated and it's strongly recommended to switch to iw and nl80211.
Some of your existing packages may need a new version after the kernel update. Ksplice takes care of all security updates but it depends on the updates and it's not free. You also have the option of using kexec which will require a reboot but will skip the hardware part of the boot.
iw is a new nl80211 based CLI configuration utility for wireless devices.A monitor interface with no additional monitor flags can be created as follows: The nice thing about these type of alternative monitor interfaces is you can further extend radiotap even with vendor extensions to add more data to radiotap to help debug device specific features.Keep in mind this requires drivers to honor mac80211's flag requests strictly, so drivers like ath5k and ath9k which still enable flags based on operation mode need to be fixed to take advantage of this.After installation, Linux requires configuration and systems administration.Corporate systems need monitoring, backups, updates, as well as system and user management.Do note that even if your admin is trying to install an excluded package from your RHN Satellite server via the normal process, it will still fail due to the local configuration.
