Why does the sysctl command no longer accept a group/parent as an argument on RHEL6?

Solution Unverified - Updated -

Issue

  • On RHEL5, the sysctl tool let you specify a group/parent as the argument and all items below that would be printed.  For example:

    [root@rhel5.6 ~]# sysctl net.core
net.core.netdev_budget = 300
net.core.somaxconn = 128
net.core.xfrm_larval_drop = 0
net.core.xfrm_acq_expires = 30
...

  • On RHEL6, this no longer works:

    [root@rhel6.0 ~]# sysctl net.core
error: "Invalid argument" reading key "net.core"
